                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 1997
                                   (unaudited)

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The Company The consolidated  financial information in this report includes
the  accounts  of Key  Energy  Group,  Inc.  (the  "Company"  or "Key")  and its
wholly-owned  subsidiaries  and  was  prepared  in  conformity  with  accounting
policies  used in the Annual  Report on Form 10-K  furnished  for the  preceding
fiscal  year.  

     As of November 14, 1997, the Company operated a fleet of approximately  775
well service  rigs,  608 fluid  hauling and other  trucks,  and 27 drilling rigs
(including 17 workover rigs, 14 trucks, and six drilling rigs in Argentina). The
Company  believes that, as of November 14, 1997, Key's well service and workover
rig fleet and fluid hauling and other truck fleet were the largest active fleets
onshore  in the  continental  United  States  and the  second  largest  fleet in
Argentina.  The Company  operates in most onshore oil and natural gas  producing
regions  of  the  continental  United  States  and  provides  a  full  range  of
maintenance and workover services to major and independent oil and gas companies
in all its operating regions.  In addition to maintenance and workover services,
Key also provides  services which include the completion of newly drilled wells,
the re-completion of existing wells (including horizontal recompletions) and the
plugging  and  abandonment  of  wells at the end of their  useful  lives.  Other
services include oil field fluid transportation,  storage and disposal services,
frac tank rentals,  fishing and rental tools,  wire-line services,  air drilling
and hot oiling. In addition, the Company is engaged in contract drilling in West
Texas and  Argentina  and owns and  produces  oil and natural gas in the Permian
Basin. 

     The  Company  conducts  its  domestic  operations   primarily  through  six
wholly-owned subsidiaries:  Yale E. Key, Inc. ("Yale E. Key"); WellTech Eastern,
Inc.  ("WellTech  Eastern");  Key Four Corners,  Inc. ("Key Four Corners");  Key
Rocky Mountain,  Inc. ("Key Rocky Mountain");  Odessa  Exploration  Incorporated
("Odessa  Exploration");  and Key Energy Drilling, Inc. ("Key Energy Drilling").
In  addition,  Key  operates  in  Argentina  through its  indirect  wholly-owned
subsidiaries,   Servicios  WellTech  S.A.  ("Servicios")  and  Kenting  Drilling
(Argentina) S.A. ("Kenting"). WellTech Eastern operates through three divisions:
WellTech  Mid-Continent  Division,  WellTech  Eastern  Division  and Brooks Well
Servicing Division.  Yale E. Key, WellTech Eastern,  Key Four Corners, Key Rocky
Mountain,  Servicios  and  Kenting  provide  oil and gas well  services.  Odessa
Exploration  is  engaged  in the  production  of oil and  gas,  and  Key  Energy
Drilling,  Servicious,  Kenting,  Brooks Well  Servicing  Division  and Key Four
Corners provide contract oil and gas well drilling services.

     Odessa Exploration utilizes the successful efforts method of accounting for
its oil and gas  properties.  Under  this  method,  all  costs  associated  with
productive wells and  nonproductive  development  wells are  capitalized,  while
nonproductive  exploration  costs and geological and geophysical costs (if any),
are expensed. Capitalized costs relating to proved properties are depleted using
the  unit-of-production  method  based  on  proved  reserves  expressed  as  net
equivalent barrels as reviewed by independent petroleum engineers.  The carrying
amounts of properties  sold or otherwise  disposed of and the related  allowance
for depletion are eliminated  from the accounts and any gain/loss is included in
results of operations. Odessa Exploration's aggregate oil and gas properties are
stated at cost,  not in excess of total  estimated  future net  revenues  net of
related income tax effects.

3.  LONG-TERM DEBT

     As of  September  30,  1997,  the  Company had three  major  components  of
long-term debt which are more fully described below.

7% Convertible Subordinated Debentures

     In July 1996,  the Company  completed  the  offering of  $52,000,000  of 7%
Convertible Subordinated Debentures due 2003 (the"7% Debentures"). The offering
was a private  offering  pursuant to Rule 144A under the Securities  Act. As the
result of the conversion of a significant  portion of the 7% Debentures into the
Company's common stock as more fully described  below,  the remaining  principal
balance at September 30, 1997 was $4,600,000. The remaining 7% Debentures mature
on July 1, 2003 and  remain  convertible  at any time  before  maturity,  unless
previously  redeemed,  into shares of the Company's common stock at a conversion
price of $9 3/4 per share, subject to adjustment in certain events. In addition,
the remaining  holders of the  Debentures who convert prior to July 1, 1999 will
be entitled to receive,  in addition to the Company's  common  stock,  a payment
equal to 50% of the interest otherwise payable on the converted  Debentures from
the date of conversion through July 1, 1999, payable in cash or common stock, at
the  Company's  option.  Interest  on the  remaining  7%  Debentures  is payable
semi-annually  on  January  1 and  July 1 of each  year.  The  Company  has made
interest payments on the 7% Debentures on January 1, 1996 and July 1, 1997.

     As of  September  30,  1997,  $47,400,000  in  principal  amount  of the 7%
Debentures had been converted  into the Company's  common stock.  The conversion
was at the option of the holders. The Debentures converted into 5,062,369 shares
of the Company's common stock. The conversion  included 200,831 shares in excess
of the number of shares  issuable  at the  conversion  price of $9.75 per share.
Such  additional  consideration  will be  accounted  for as an  increase  to the
Company's  equity. In addition,  the proportional  amount of debt issuance costs
associated with the converted  Debentures will be accounted for as a decrease to
the Company's equity.

PNC Credit Agreement

     On June 6, 1997,  the Company  entered into an  agreement  (the"PNC Credit
Agreement") with PNC Bank, N.A., as  administrative  agent,  Norwest Bank Texas,
N.A. , as collateral agent, Lehman Commercial Paper, Inc., as advisor,  arranger
and  syndication  agent and the  lenders  named  therein  pursuant  to which the
lenders  provided a $255 million credit  facility,  consisting of a $120 million
seven-year term loan and a $135 million five-year revolver. The interest rate on
the term loan was LIBOR plus 2.75  percent.  The  interest  rate on the revolver
varied  based on the LIBOR and the level of the  Company's  indebtedness  and at
September 30, 1997 was LIBOR plus 2.25 percent.  The credit  facility  contained
certain  restrictive  covenants  and  requires  the Company to maintain  certain
financial ratios. At September 30, 1997, the principal balance of the PNC Credit
Agreement  revolver was $57 million and there was  approximately  $78 million in
unused credit line facilities.

     On September  25, 1997,  the Company  repaid the term loan and a portion of
the amount then  outstanding  under the  revolver  using the  proceeds  from the
initial closing of the Company's private  placement of the 5% Notes,  (discussed
below).  On October 7, 1997,  the Company  again prepaid a portion of the amount
then  outstanding  under the revolver using the proceeds from the second closing
of the Company's private placement of the 5% Notes (discussed below).  Effective
as of November 6, 1997, the Company completed the re-negotiation of the

     PNC Credit  Agreement  by entering  into an amended and restated PNC Credit
Agreement   providing  for,  among  other  things,   an  increase  in  borrowing
availability under the revolver from $135 million to $200 million and a decrease
in the revolver's  interest rate from LIBOR plus 2.25 percent to LIBOR plus 1.25
percent.

5% Subordinated Notes

     On September  25,  1997,  the Company  completed an initial  closing of its
private placement of $200 million of 5% Convertible  Subordinated Notes due 2004
(the "5% Notes").  On October 7, 1997, the Company completed a second closing of
its private  placement of an additional  $16 million of the 5% Notes pursuant to
the exercise of the remaining portion of an over-allotment option granted to the
initial  purchasers  of the 5%  Notes.  The  placement  was a  private  offering
pursuant to Rule 144A under the Securities  Act. The 5% Notes bear interest at a
5% coupon rate and are convertible  into shares of the Company's common stock at
a conversion  price of $38.50 per share at the holder's option on the earlier of
(i) the date that the  registration  statement  on Form S-3 required to be filed
with the Securities and Exchange Commission (the "Commission")  covering resales
of the 5% Notes  and the  underlying  common  stock by the  holders  thereof  is
declared  effective  by the  Commission  and  (ii)  270  days  from  the date of
issuance. Interest is payable on March 15 and September 15, commencing March 15,
1998. The 5% Notes are redeemable at the Company's  option on or after September
15, 2000, in whole or part, together with accrued and unpaid interest.  Proceeds
from the private  placement  of the 5% Notes were used to repay the  outstanding
balances under the Company's  revolving  credit  facility and term loan facility
(see above).

4.  RECENTLY ISSUED ACCOUNTING STANDARDS

Statement of Financial Accounting Standards No. 128 - Earnings per Share

     Statement of Financial Accounting Standards No. 128 ("SFAS 128") - Earnings
per Share,  is effective for periods ending on or after December 15, 1997.  SFAS
128 replaces the  presentation  of primary  earnings per share  ("EPS") with the
presentation  of basic EPS, which excludes  dilution and is computed by dividing
income available to common shareholders by the weighted-average number of common
shares  outstanding for the period.  SFAS 128 also requires dual presentation of
basic EPS and diluted  EPS on the face of the income  statement  and  requires a
reconciliation  of the numerators and denominators of basic EPS and diluted EPS.
Management  believes the adoption of SFAS 128 will not have a material effect on
its financial position or results of operations of the Company.

Statement  of   Financial   Accounting   Standards   No.  130  -  Reporting
Comprehensive Income

     Statement  of  Financial  Accounting  Standards  No.  130  ("SFAS  130")  -
Reporting  Comprehensive  Income,  is effective for fiscal years beginning after
December 15, 1997.  Reclassification of financial statements for earlier periods
provided for comparative  purposes is required.  The Company will adopt SFAS 130
for the fiscal year ended June 30,  1999.  Management  believes  the adoption of
SFAS 130 will not have a material effect on its financial position or results of
operations of the Company.

Statement of Financial  Accounting  Standards No. 131 -  Disclosures  about
Segments of an Enterprise and Related Information

     Statement  of  Financial  Accounting  Standards  No.  131  ("SFAS  131")  -
Disclosures  about  Segments  of  an  Enterprise  and  Related  Information,  is
effective for financial  statements  for periods  beginning  after  December 15,
1997.  SFAS 131 need not be  applied  to  interim  financial  statements  in the
initial year of its application.  However,  comparative  information for interim
periods in the initial year of  application  is to be reported in the  financial
statements for interim  periods in the second year of  application.  The Company
will adopt SFAS 131 for the fiscal year ended June 30, 1999. Management believes
the  adoption  of SFAS  131 will not have a  material  effect  on its  financial
position or results of operations of the Company.

5.  COMMITMENTS AND CONTINGENCIES

     Various  suits and claims  arising in the  ordinary  course of business are
pending against the Company. Management does not believe that the disposition of
any of these items will result in a material  adverse impact to the consolidated
financial position of the Company.

         OPERATIONS AND FINANCIAL CONDITION.


     The following  discussion and analysis  should be read in conjunction  with
the Company's audited Form 10-K for the year ended June 30, 1997.

September  30,  1997,  the  Company  purchased  the  remaining  37%  interest in
Servicios WellTech Argentina and completed the acquisition of six well servicing
and trucking companies: Patrick Well Service, Kenting Holdings (Argentina) S.A.,
Mosley Well Service,  Ram/Rowland Oil Well Service,  Landmark Fishing and Rental
and Waco Oil and Gas.  These  acquisitions,  (which are more fully  described in
Note 2), collectively operate 97 well service rigs (including six in Argentina),
108 fluid  hauling and other trucks and six drilling  rigs,  including  three in
Argentina.

     Subsequent  to September  30, 1997,  the Company has announced or completed
the  acquisition  of six  well  service  companies  and  two  contract  drilling
companies which,  collectively,  operate 164 well service rigs, 17 drilling rigs
and 118 fluid  hauling and other  trucks.  These eight  announced  or  completed
acquisitions,  (which are more fully  described  in Note 2),  have  allowed  the
Company to expand its  operating  presence  into markets it  previously  did not
serve,  including  the  Rocky  Mountains  and the Four  Corners  area.  Assuming
completion of the pending  acquisitions,  Key's operations will include 790 well
service and workover rigs, 623 fluid hauling and other trucks,  33 drilling rigs
and numerous ancillary operations.  Based upon the number of active well service
rigs and fluid hauling and other trucks that the Company would operate  assuming
the  completion of all  announced  acquisitions,  the Company  believes that Key
Energy Group,  Inc. will be the largest onshore well service provider within the
continental  United  States and the second  largest  well  service  provider  in
Argentina.

Future Growth Strategy

     Historically, the domestic well service rig and production service industry
has been highly fragmented, characterized by a large number of smaller companies
which have  competed  effectively  on a local  basis in terms of pricing and the
quality  of  services  offered.  In  recent  years,   however,  many  major  and
independent oil and gas companies have placed increasing  emphasis upon not only
pricing,  but also on safety records and quality  management systems of, and the
breadth  of  services  offered  by,  their  vendors,  including  well  servicing
contractors. This market environment, which requires significant expenditures by
smaller companies to meet these increasingly rigorous standards, has forced many
smaller well servicing companies to sell their operations to larger competitors.
As a result,  the  industry  has seen high  levels  of  consolidation  among the
competing contractors.

     Over the past eighteen  months,  Key has been the leading  consolidator  of
this industry,  completing twenty-six  acquisitions of well servicing operations
(32,  including pending transactions and transaction completed subsequent
to September 30, 1997). This  consolidation has led to reduced  fragmentation in
the market and has led to more  predictable  demand  for well  services  for the
Company and its competitors. Key's management structure is decentralized,  which
allows for rapid  integration of acquisitions  and the retention of strong local
identities  of many of the acquired  businesses.  As a result of these and other
factors, the Company has developed a growth strategy to: (i) identify, negotiate
and  consummate   additional   acquisitions  of  complementary   well  servicing
operations, including rigs, trucking and

                                 - 13 -

other  ancillary  services;  (ii)  fully-integrate  acquisitions  into  the
Company's decentralized organizational structure and thereby attempt to maximize
operating  margins;  (iii) expand  business  lines and  services  offered by the
Company in existing  areas of operations;  and (iv) extend the geographic  scope
and operating environments for the Company's operations.

RESULTS OF OPERATIONS

QUARTER ENDED SEPTEMBER 30, 1997 VERSUS QUARTER ENDED SEPTEMBER 30, 1996

     The   following   discussion   provides   information   to  assist  in  the
understanding of the Company's financial condition and results of operations. It
should be read in  conjunction  with the financial  statements and related notes
appearing elsewhere in this report.

Operating Income

The Company

     Revenues of the Company for the quarter ended  September 30, 1997 increased
$44,094,000,  or 140%, from $31,462,000 for the quarter ended September 30, 1996
to  $75,556,000  for the  current  quarter.  Net  income for the  quarter  ended
increased  $3,384,000,  or 218%, from $1,554,000 for the quarter ended September
30, 1996 to $4,938,000 for the current quarter. The increase in revenues and net
income  was  primarily  due  to  the  completed  acquisitions  of  well  service
operations (see Note 2), increased oil and gas revenues from Odessa Exploration,
and a general increase in oil-well service equipment utilization.

Oilfield Services

     Oilfield service revenues increased $42,187,000,  or 154%, from $27,311,000
for the  quarter  ended  September  30,  1996,  to  $69,498,000  for the current
quarter.  The increase in revenues is primarily  attributable to acquisitions as
well as higher  equipment use and pricing  resulting  from an increase in demand
for oilfield services.

Oil and Natural Gas Exploration and Production

     Revenues  from oil and gas  activities  increased  $629,000,  or 41%,  from
$1,525,000  for the quarter ended  September  30, 1996,  to  $2,154,000  for the
current quarter.  The increase in revenues was primarily the result of increased
production  of oil and natural  gas as several oil and natural gas wells,  which
were drilled during fiscal 1997 began  production and higher oil and natural gas
prices for the current  period.  Of the total  $2,154,000  of  revenues  for the
quarter ended September 30, 1997,  approximately $1,852,000 was from the sale of
oil and  natural  gas with the  remainder  of  $302,000  representing  primarily
administrative fee income.

Oil and Natural Gas Well Drilling

     Oil and natural gas well drilling revenues increased $499,000, or 22%, from
$2,324,000  for the  quarter  ended  September  30, 1996 to  $2,823,000  for the
current  quarter.  The increase in revenues is primarily  attributable to higher
equipment utilization and an increase in pricing.

Operating Expenses
 
Oilfield Services

     Oilfield service expenses increased $28,539,000,  or 145%, from $19,700,000
for the quarter ended September 30, 1996 to $48,239,000 for the current quarter.
The increase was due  primarily to  acquisitions  and the  increased  demand for
oilfield  services.  In  addition,  the  Company  has  continued  to expand  its
services,  offering ancillary services and equipment such as well fishing tools,
blow-out preventers and well frac tanks.

Oil and natural Gas Exploration and Production

     Expenses related to oil and gas activities increased $424,000, or 83%, from
$513,000  for the quarter  ended  September  30,  1996 to  $937,000  for current
quarter.  The  increase  in  expenses  was  primarily  the  result of  increased
production  of oil and natural  gas as several oil and natural gas wells,  which
were drilled during fiscal 1997, began production during the quarter.

Oil and Natural Gas Well Drilling

     Expenses related to oil and natural gas well drilling activities  increased
$382,000,  or 20%,  from  $1,881,000  for the quarter  ended  September 30, 1996
$2,263,000  for current  quarter.  The increase in expenses is  attributable  to
higher equipment utilization and increased revenues.

Depreciation, Depletion and Amortization Expense

     Depreciation,  depletion and amortization expense increased $3,052,000,  or
146%, from $2,095,000 for the quarter ended September 30, 1996 to $5,147,000 for
the  current  quarter.  The  increase  is  primarily  due  to  oilfield  service
depreciation expense,  which is the result of increased oilfield service capital
expenditures for the current period versus the prior period and the acquisitions
of oilfield service assets.

General and Administrative Expenses

     General and  administrative  expenses increased  $4,174,000,  or 118%, from
$3,527,000  for the  quarter  ended  September  30, 1996 to  $7,701,000  for the
current quarter. The increase was primarily attributable to the Company's recent
acquisitions and expanded services.

Interest Expense

     Interest  expense  increased  $2,088,000,  or 155%, from $1,350,000 for the
quarter  ended  September 30, 1996 to $3,438,000  for the current  quarter.  The
increase was primarily the result of increased  indebtedness  as a result of the
Company's acquisition program.

Income Taxes

     Income tax expense  increased  $2,109,000,  or 269%,  from $784,000 for the
quarter ended  September 30, 1996, to $2,893,000  for the current  quarter.  The
increase in income taxes is primarily due to the  increases in operating  income
and a higher  effective  tax rate.  However,  the Company  does not expect to be
required to remit the total amount of the $2,893,000 in total federal income tax
expense for the quarter ended September 30, 1997, because of the availability of
net operating  loss  carryforwards,  accelerated  tax  depreciation  and oil and
natural gas drilling tax attributes.

                                 - 15 -

Cash Flow

     Net cash provided by operating  activities  increased  $1,044,000,  or 35%,
from  $3,016,000  during the quarter ended September 30, 1996, to $4,060,000 for
the current quarter. The increase is attributable  primarily to increases in net
income and depreciation, depletion and amortization which was largely off-set by
a decrease in accounts receivable.

     Net cash used in investing activities increased $128,309,000, or 362%, from
$3,545,000  during the quarter ended  September 30, 1996,  $131,854,000  for the
current  quarter.  The  increase is primarily  the result of  increased  capital
expenditures  for  well  service  operations  as  well as the  Company's  recent
acquisitions.

     Net cash provided by financing activities increased $120,241,000,  or 795%,
from  $15,125,000  during the quarter ended  September 30, 1996, to $135,366,000
for the current  quarter.  The increase is primarily  the result of the proceeds
from long-term  commercial  paper and borrowings under  line-of-credit,  and the
issuance of the Company's 5% Notes (see Note 2) which are  partially  off-set by
the repayment of long-term debt.

LIQUIDITY AND CAPITAL RESOURCES

     The  Company's  cash  increased  by  $7.6  million  for the  quarter  ended
September 30, 1997 from $41.7 as of June 30, 1997 to $49.3 million.

     The Company has projected $40 million for capital  expenditures  for fiscal
1998, as compared to $24.8  million for fiscal 1997.  Oilfield  service  capital
expenditures  for the three  months ended  September  30, 1997 were $6.7 million
compared to $2.9 million  during the same quarter last year.  Of the total $40.0
million in capital  expenditures  the  Company is  projecting  for fiscal  1998,
approximately  $30 million is expected to be  attributable  to oilfield  service
operations.  Capital  expenditures  are  expected  to be  primarily  capitalized
improvement  costs to existing  equipment and machinery.  The Company expects to
finance these  capital  expenditures  utilizing the operating  cash flows of the
Company.

     The Company's oil and natural gas exploration  and  development  operations
are forecasting  outlays of approximately  $8.0 million in development costs for
fiscal 1998,  as compared to $8.2 million  during  fiscal 1997.  For the quarter
ended September 30, 1997, these outlays totaled $2.1 million as compared to none
for the quarter  ended  September  30, 1996.  Financing is expected to come from
operations and available credit facilities.

     The Company's oil and natural gas well  drilling  operations  have forecast
approximately $2.0 million in oil and natural gas drilling capital  expenditures
for fiscal  1998,  as compared  to $1.5  million  during  fiscal  1997.  Capital
expenditures are primarily for improvements to existing equipment and machinery.
For the quarter ended September 30, 1997, capital  expenditures totaled $339,000
as compared to $323,000 for the quarter ended  September 30, 1996.  Financing is
expected to come from existing cash flow.

Debt

7% Convertible Subordinated Debentures

     In July 1996,  the Company  completed  the  offering of  $52,000,000  of 7%
Convertible Subordinated Debentures due 2003 (the "7% Debentures"). The offering
was a private  offering  pursuant to Rule 144A under the Securities  Act. As the
result of the conversion of a significant  portion of the 7% Debentures into the
Company's common stock as more fully described  below,  the remaining  principal
balance at September 30,

                                   (unaudited)

1997 was $4,600,000. The remaining 7% Debentures mature on July 1, 2003 and
remain convertible at any time before maturity, unless previously redeemed, into
shares of the Company's  common stock at a conversion price of $9 3/4 per share,
subject to adjustment in certain events.  In addition,  the remaining holders of
the Debentures who convert prior to July 1, 1999 will be entitled to receive, in
addition to the Company's  common stock,  a payment equal to 50% of the interest
otherwise  payable  on the  converted  Debentures  from the  date of  conversion
through July 1, 1999,  payable in cash or common stock, at the Company's option.
Interest on the remaining 7% Debentures  is payable  semi-annually  on January 1
and July 1 of each  year.  The  Company  has made  interest  payments  on the 7%
Debentures on January 1, 1996 and July 1, 1997.

     As of  September  30,  1997,  $47,400,000  in  principal  amount  of the 7%
Debentures had been converted  into the Company's  common stock.  The conversion
was at the option of the holders. The Debentures converted into 5,062,369 shares
of the Company's common stock. The conversion  included 200,831 shares in excess
of the number of shares  issuable  at the  conversion  price of $9.75 per share.
Such  additional  consideration  will be  accounted  for as an  increase  to the
Company's  equity. In addition,  the proportional  amount of debt issuance costs
associated with the converted  Debentures will be accounted for as a decrease to
the Company's equity.

PNC Credit Agreement

     On June 6, 1997,  the Company  entered into an  agreement  (the "PNC Credit
Agreement") with PNC Bank, N.A., as  administrative  agent,  Norwest Bank Texas,
N.A. , as collateral agent, Lehman Commercial Paper, Inc., as advisor,  arranger
and  syndication  agent and the  lenders  named  therein  pursuant  to which the
lenders  provided a $255 million credit  facility,  consisting of a $120 million
seven-year term loan and a $135 million five-year revolver. The interest rate on
the term loan was LIBOR plus 2.75  percent.  The  interest  rate on the revolver
varied  based on the LIBOR and the level of the  Company's  indebtedness  and at
September 30, 1997 was LIBOR plus 2.25 percent.  The credit  facility  contained
certain  restrictive  covenants  and  requires  the Company to maintain  certain
financial ratios. At September 30, 1997, the principal balance of the PNC Credit
Agreement  revolver was $57 million and there was  approximately  $78 million in
unused credit line facilities.

     On September  25, 1997,  the Company  repaid the term loan and a portion of
the amount then  outstanding  under the  revolver  using the  proceeds  from the
initial closing of the Company's private  placement of the 5% Notes,  (discussed
below).  On October 7, 1997,  the Company  again prepaid a portion of the amount
then  outstanding  under the revolver using the proceeds from the second closing
of the Company's private placement of the 5% Notes (discussed below).  Effective
as of November 6, 1997,  the Company  completed  the  re-negotiation  of the PNC
Credit  Agreement by entering into an amended and restated PNC Credit  Agreement
providing for, among other things, an increase in borrowing  availability  under
the revolver from $135 million to $200 million and a decrease in the  revolver's
interest rate from LIBOR plus 2.25 percent to LIBOR plus 1.25 percent.

5% Subordinated Notes

     On September  25,  1997,  the Company  completed an initial  closing of its
private placement of $200 million of 5% Convertible  Subordinated Notes due 2004
(the "5% Notes").  On October 7, 1997, the Company completed a second closing of
its private  placement of an additional  $16 million of the 5% Notes pursuant to
the exercise of the remaining portion of an over-allotment option granted to the
initial  purchasers  of the 5%  Notes.  The  placement  was a  private  offering
pursuant to Rule 144A under the Securities Act. The 5% Notes bear interest

at a 5% coupon rate and are convertible into shares of the Company's common
stock at a conversion  price of $38.50 per share at the  holder's  option on the
earlier of (i) the date that the registration  statement on Form S-3 required to
be filed with the Securities and Exchange Commission (the "Commission") covering
resales of the 5% Notes and the underlying  common stock by the holders  thereof
is  declared  effective  by the  Commission  and (ii) 270 days  from the date of
issuance. Interest is payable on March 15 and September 15, commencing March 15,
1998. The 5% Notes are redeemable at the Company's  option on or after September
15, 2000, in whole or part, together with accrued and unpaid interest.  Proceeds
from the private  placement  of the 5% Notes were used to repay the  outstanding
balances under the Company's  revolving  credit  facility and term loan facility
(see above).

Impact of Recently Issued Accounting Standards

Statement of Financial Accounting Standards No. 128 - Earnings per Share

     Statement of Financial Accounting Standards No. 128 ("SFAS 128") - Earnings
per Share,  is effective for periods ending on or after December 15, 1997.  SFAS
128 replaces the  presentation  of primary  earnings per share  ("EPS") with the
presentation  of basic EPS, which excludes  dilution and is computed by dividing
income available to common shareholders by the weighted-average number of common
shares  outstanding for the period.  SFAS 128 also requires dual presentation of
basic EPS and diluted  EPS on the face of the income  statement  and  requires a
reconciliation  of the numerators and denominators of basic EPS and diluted EPS.
Management  believes the adoption of SFAS 128 will not have a material effect on
its financial position or results of operations of the Company.

Statement  of   Financial   Accounting   Standards   No.  130  -  Reporting
Comprehensive Income

     Statement  of  Financial  Accounting  Standards  No.  130  ("SFAS  130")  -
Reporting  Comprehensive  Income,  is effective for fiscal years beginning after
December 15, 1997.  Reclassification of financial statements for earlier periods
provided for comparative  purposes is required.  The Company will adopt SFAS 130
for the fiscal year ended June 30,  1999.  Management  believes  the adoption of
SFAS 130 will not have a material effect on its financial position or results of
operations of the Company

     Statement of Financial  Accounting  Standards No. 131 -  Disclosures  about
Segments of an Enterprise and Related Information

     Statement  of  Financial  Accounting  Standards  No.  131  ("SFAS  131")  -
Disclosures  about  Segments  of  an  Enterprise  and  Related  Information,  is
effective for financial  statements  for periods  beginning  after  December 15,
1997.  SFAS 131 need not be  applied  to  interim  financial  statements  in the
initial year of its application.  However,  comparative  information for interim
periods in the initial year of  application  is to be reported in the  financial
statements for interim  periods in the second year of  application.  The Company
will adopt SFAS 131 for the fiscal year ended June 30, 1999. Management believes
the  adoption  of SFAS  131 will not have a  material  effect  on its  financial
position  or  results  of  operations  of the  Company  Impact of  Inflation  on
Operations

     Although in our complex  environment  it is extremely  difficult to make an
accurate  assessment  of the impact of  inflation on the  Company's  operations,
management is of the opinion that inflation has not had a significant  impact on
its business.

restrictive in any court  proceeding,  the court may reduce such restrictions to
those  which  it deems  reasonable  under  the  circumstances.  The  obligations
expressed in this Section 3.1 are in addition to any other  obligations that the
Shareholder  may have  under the laws of the  states  in which he does  business

Company,  Buyer or any affiliate of Buyer may, in addition to the other remedies
which may be  available  to it  hereunder,  file a suit in equity to enjoin such
Shareholder  from such breach or threatened  breach.  If any  provisions of this
Section  3.1 are held to be invalid  or against  public  policy,  the  remaining

covenants set forth in this Section 3.1 are being executed and delivered by such
Shareholder  in  consideration  of the  covenants  of  Buyer  contained  in this
Agreement,  and for other good and valuable  consideration,  receipt of which is
hereby acknowledged.

party hereto,  any other party hereto shall execute and deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to

obligations,  liabilities, recoveries, suits, causes of action and deficiencies,

consultants and experts  (collectively,  the ADamages@) in excess of $150,000 in

arise, result from or relate to any breach by the Shareholder of (or the failure
of the  Shareholder  to perform)  his  respective  representations,  warranties,
covenants  or  agreements  in this  Agreement or in any  schedule,  certificate,
exhibit or other  instrument  furnished or delivered to Buyer by the Shareholder
under this Agreement or provided,  however,  that the  Shareholder  shall not be
required to so indemnify,  defend and hold harmless  Buyer  Indemnified  Parties
against and with respect to any Damages  incurred as a result of a breach by the
Shareholder  of his  representations  and warranties in this Agreement or in any
schedule,  certificate,  exhibit or other  instrument  furnished or delivered to
Buyer by the  Shareholder  under this Agreement for which Buyer fails to provide
written  notice of a claim for such Damages to the  Shareholder on or before the
expiration  of the survival  period (as  specified in Section 5.1 hereof) of the

administrators  (collectively  the AShareholder  Indemnified  Parties@) from any
Damages that the Shareholder  Indemnified  Parties shall incur or suffer,  which
arise, result from or relate to (i) any breach of or failure by Buyer to perform
any  of  its  representations,  warranties,  covenants  or  agreements  in  this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to the Shareholder by or on behalf of Buyer under this Agreement or
(ii)  the  conduct  of the  Company=s  business  on or after  the  date  hereof,
provided,  however, that Buyer shall not be required to so indemnify, defend and

Buyer of any of its  representations  and warranties in this Agreement or in any
schedule, certificate, exhibit or other instrument furnished or delivered to the
Shareholder  by Buyer under this  Agreement for which the  Shareholder  fails to
provide  written  notice of the claim for such damages to Buyer on or before the
expiration  of the survival  period (as  specified in Section 5.1 hereof) of the
specific representation or warranty alleged to have been breached.

     4.2.  Indemnification  Procedure.  In  the  event  that  any  party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 4.1 or 4.2 of this Agreement,  such indemnified party shall give written
notice to the  indemnifying  party,  specifying  such claim,  and may thereafter
exercise any remedies  available to such party under this  Agreement;  provided,
however,  that the failure of any  indemnified  party to give notice as provided
herein shall not relieve the indemnifying party of any obligations hereunder, to
the extent the indemnifying party is not materially prejudiced thereby. Further,
promptly  after receipt by an indemnified  party  hereunder of written notice of
the  commencement  of any action or proceeding with respect to which a claim for
indemnification  may be  made  pursuant  to  Section  4.1 or  4.2  hereof,  such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying  party,  give written notice to the latter of the  commencement  of
such action;  provided,  however,  that the failure of any indemnified  party to
give notice as provided herein shall not relieve the  indemnifying  party of any
obligations  hereunder,  to the extent the indemnifying  party is not materially
prejudiced  thereby.  In case any such action is brought  against an indemnified
party, the indemnifying  party shall be entitled to participate in and to assume
the  defense  thereof,  jointly  with any  other  indemnifying  party  similarly
notified,  to the extent that it may wish, with counsel reasonably  satisfactory
to such indemnified  party, and after such notice from the indemnifying party to
such  indemnified  party of its election so to assume the defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in  the  same  jurisdiction   arising  out  of  the  same  general  allegations.
Notwithstanding any of the foregoing to the contrary, the indemnified party will
be  entitled  to select its own  counsel  and  assume the  defense of any action
brought against it if the indemnifying  party fails to select counsel reasonably
satisfactory to the indemnified  party,  the expenses of such defense to be paid
by the indemnifying  party. No indemnifying  party shall consent to entry of any
judgment  or enter  into any  settlement  with  respect to a claim  without  the
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld,  or unless such  judgment or settlement  includes as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability with respect to such claim. No indemnified party
shall consent to entry of any judgment or enter into any  settlement of any such
action, the defense of which has been assumed by an indemnifying party,  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld or delayed.

representations and warranties  contained in Section 2.1.11 hereof shall survive
until the expiration of the applicable  statute of limitations  associated  with

follows:



C:\DOCUMENT\KENTSTAG.07
                                        i

                                    ARTICLE 1

                                Purchase and Sale

     1.1.  Purchase  and Sale of the  Company  Shares.  Subject to the terms and
conditions of this Agreement, on the date hereof, the Shareholder agrees to sell
and  convey to Buyer,  free and clear of all  Encumbrances  (defined  below) and
Buyer  agrees to purchase  and accept from the  Shareholder,  all of the Company
Shares and all of the  Shareholder-Owned  Subsidiary Shares. In consideration of
the sale of the  Company  Shares and the  Shareholder-Owned  Subsidiary  Shares,
Buyer  shall  pay to the  Shareholder  $9,575,000  in cash by wire  transfer  of
immediately  available  funds,  and the Cash  Adjustment  Payment (as defined in
Section 1.3 hereof), if any, in accordance with Section 1.3 hereof. In addition,
on the date hereof Buyer shall pay to the  Shareholder  $525,000 in satisfaction
of all debts  remaining  due to the  Shareholder  or irs  affiliates on the date
hereof. The term "Encumbrances"  means all liens,  security interests,  pledges,
mortgages,  deed of trust, claims,  rights of first refusal,  options,  charges,
restrictions or conditions to transfer or assignment, liabilities,  obligations,
privileges,  equities,  easements,  rights-of-way,   limitations,  reservations,
restrictions and other encumbrances of any kind or nature.

     1.2.  Recording the Transfer of Shares. The parties hereto acknowledge that
the Company  Shares are currently held of record as follows:  15,299,988  shares
(the  "KID  Company  Shares")  by  Kenting  Drilling   International,   Inc.,  a
predecessor  (by  amalgamation)  to the  Shareholder  ("KID") and 12 shares (the
"KESL  Company  Shares")  by Kenting  Energy  Services  Ltd, a  predecessor  (by
amalgamation) to the Shareholder  ("KESL").  The parties hereto acknowledge that
the Shareholder-  Owned  Subsidiary  Shares are currently held of record by KID.

the KID  Company  Shares,  the KESL  Company  Shares  and the  Shareholder-Owned
Subsidiary  Shares by means of an amalgamation of various  affiliated  corporate
entities and a subsequent  liquidation  of the resulting  entity  without having
such acquisitions (the "Shareholder  Stock  Acquisitions")  formally recorded in
the appropriate stock records of the Company and the Company Subsidiary.  On the
date hereof,  the Shareholder  shall caused to be filed in the appropriate stock
records of the Company  and the  Company  Subsidiary  those  transfer  documents
necessary to properly  record the Shareholder  Stock  Acquisitions in accordance
with  Argentina  law (the  "Delinquent  Filings") and those  transfer  documents
necessary  to  properly  record  the  transfer  of the  Company  Shares  and the
Shareholder-Owned  Shares  hereunder in accordance with Argentina law such that,
as a result of such  filings,  the Buyer  (and its  designees)  will  become the
record and  beneficial  owners of the Company  Shares and the  Shareholder-Owned
Subsidiary Shares.
 
     1.3  Adjustment  of Purchase  Price.  Buyer shall cause to be prepared  and
delivered to the  Shareholder a consolidated  balance sheet of the Company as of
the date hereof (the "Final  Balance  Sheet")  within  sixty (60) days after the
date hereof,  which balance  sheet will be prepared in accordance  with Canadian
generally accepted accounting  principles,  consistently applied in all respects
(which  shall not  include  any reserve or  accruals  for  employee  termination
costs).  Buyer and the Shareholder shall jointly review the Final Balance Sheet,
and endeavor in good faith to resolve all  disagreements  regarding  the entries
thereon and reach a final determination thereof within 90 days

                                        2

     from the date  hereof.  In the event that the parties  cannot  agree on the
entries to be placed on the Final Balance Sheet, the dispute will be resolved by
an independent  accounting  firm mutually agreed to by the Shareholder and Buyer
(such  agreement not to be  unreasonably  withheld or delayed) whose  resolution
shall be binding on and enforceable  against the parties hereto.  Within 10 days
of reaching such final determination,  the following adjusting payments shall be
made:

     (1) If the sum of (A) the Final Net Current  Value of the Company  (defined
below) plus (B) $100,056 (the"Capital Expenditure Amount") exceeds the 4/30 Net
Current Value of the Company (defined below), Buyer shall pay to the Shareholder
the amount of such excess (the "Cash Adjustment Payment").

     (2) If the sum of (A) the Final Net Current  Value of the Company  plus the
Capital  Expenditure  Amount  is less  than the 4/30  Net  Current  Value of the
Company, the Shareholder shall pay to Buyer the amount of such difference.

company  of  the  Shareholder  in  anticipation  of  the   consummation  of  the
transactions   contemplated   hereby  but   including  the  book  value  of  any
"Inventories" included in the Excluded Assets) plus the "Other Assets" minus the
"Due from Kenting Group" as recorded on the Final Balance Sheet exceeds (ii) the
'Total  Current  Liabilities"  plus the " Term Debt" plus the  "Deferred  Income
Taxes" minus the "Due to Kenting  Group" as recorded on the Final Balance Sheet.
The term"4/30 Net Current  Value of the Company"  means the dollar value of the
amount by which (i) the "Total Current Assets"  (excluding any prepaid job costs

Agreement is a valid and binding  obligation  of Buyer  enforceable  (subject to
normal   equitable   principles)  in  accordance  with  its  terms,   except  as
enforceability may be limited by bankruptcy, insolvency,  reorganization, debtor
relief or  similar  laws  affecting  the  rights  of  creditors  generally.  The
execution, delivery and performance of this Agreement by Buyer will not conflict
with or  result  in a  violation  or  breach  of any term or  provision  of,  or
constitute a default under (a) the  Certificate  of  Incorporation  or Bylaws of
Buyer or (b) any obligation, indenture, mortgage, deed of trust, lease, contract
or other agreement to which Buyer or any of its property is bound.

     2.2.3. Consents and Approvals. No consent, approval or authorization of, or
filing of a registration with, any governmental or regulatory authority,  or any
other person or entity is required to be made or obtained by Buyer in connection
with  the   execution,   delivery  or  performance  of  this  Agreement  or  the
consummation of the transactions contemplated hereby.

     2.2.4.  Finder's Fee. All  negotiations  relative to this Agreement and the
transactions  contemplated  hereby have been carried on by Buyer and its counsel
directly with the Company,  the Company  Subsidiary and the  Shareholder and its
counsel,  without the  intervention by any other person as the result of any act
of Buyer in such a manner as to give rise to any valid claim  against any of the
parties  hereto  for  any  brokerage  commission,  finder's  fee or any  similar
payments.

                              Additional Agreements

     3.1.  Noncompetition.  Except as  otherwise  consented  to or  approved  in
writing by Buyer, the Shareholder agrees that for a period of 42 months from the
date hereof,  it will not (and will cause its  affiliates  not to),  directly or
indirectly,  acting  alone or as a member  of a  partnership  or as an  officer,
director,  employee,  consultant,  representative,  holder of, or investor in as
much as 5% of any  security of any class of any  corporation  or other  business
entity (i) engage in any  businesses  involved in  providing  well  servicing or
shallow/moderate  depth drilling services within the country of Argentina;  (ii)
request  any  present  customers  or  suppliers  of the  Company or the  Company
Subsidiary  to curtail or cancel their  business  with the Company,  the Company
Subsidiary, Buyer or

C:\DOCUMENT\KENTSTAG.07
                                        7

     any affiliate of Buyer;  (iii) disclose to any person,  firm or corporation
any trade,  technical  or  technological  secrets of the  Company,  the  Company
Subsidiary, Buyer or any affiliate of Buyer or any details of their organization
or business affairs or (iv) induce or actively attempt to influence any employee
of the  Company,  the Company  Subsidiary,  Buyer or any  affiliate  of Buyer to
terminate his employment.  The  Shareholder  agrees that if either the length of
time  or  geographical  area  set  forth  in  this  Section  3.1 is  deemed  too
restrictive in any court  proceeding,  the court may reduce such restrictions to
those  which  it deems  reasonable  under  the  circumstances.  The  obligations
expressed in this Section 3.1 are in addition to any other  obligations that the
Shareholder  may have  under  the  laws of any  jurisdiction  in  which  they do
business  requiring  an employee of a business  or a  shareholder  who sells his
stock in a  corporation  (including  a  disposition  in a  merger)  to limit his
activities  so that the goodwill  and business  relations of his employer and of
the corporation whose stock he has sold (and any successor corporation) will not
be materially impaired.  Each of the Shareholder further agrees and acknowledges
that the Company,  the Company Subsidiary,  Buyer and its affiliates do not have
any  adequate  remedy  at  law  for  the  breach  or  threatened  breach  by the
Shareholder  of  this  covenant,   and  agree  that  the  Company,  the  Company
Subsidiary,  Buyer or any  affiliate  of Buyer  may,  in  addition  to the other
remedies which may be available to it hereunder, file a suit in equity to enjoin
the Shareholder from such breach or threatened breach. If any provisions of this
Section  3.1 are held to be invalid  or against  public  policy,  the  remaining
provisions shall not be affected thereby. The Shareholder  acknowledges that the
covenants set forth in this Section 3.1 are being executed and delivered by such
Shareholder  in  consideration  of the  covenants  of  Buyer  contained  in this
Agreement,  and for other good and valuable  consideration,  receipt of which is
hereby acknowledged.

     3.2.  Employee Matters.  From the date hereof,  the Company and the Company
Subsidiary   shall  remain   responsible  for  all  costs  associated  with  the
termination  of any  of  their  employees  terminated  after  the  date  hereof;
provided,  however, that the Shareholder shall be solely responsible for any and
all  liabilities,  costs and expenses  associated  with the  termination of Gary
Meier by either the Company or the Company Subsidiary,  regardless of whether he
is terminated before, on or after the date hereof (the "Meier Termination").

     3.3.  Further  Assurances.  From time to time, as and when requested by any
party hereto,  any other party hereto shall execute and deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to
effectuate the transactions contemplated hereby. Without limiting the generality
of the foregoing,  the Shareholder shall take those actions reasonably requested
by Buyer to (i)  properly  record the  transfer  of the  Company  Shares and the
Shareholder-Owned  Subsidiary  Shares in accordance  with Section 1.2 hereof and
(ii) resolve the title exceptions described in Schedule 2.1.9 hereto.

                                    ARTICLE 4

                                 Indemnification

     4.1. Indemnification by the Shareholder.  In addition to any other remedies
available to Buyer under this Agreement, or at law or in equity, the Shareholder
shall indemnify,  defend and hold harmless the Company,  the Company Subsidiary,
Buyer and their affiliates and their respective officers, directors,  employees,
agents and stockholders (collectively, the "Buyer Indemnified Parties"), against
and with respect to any and all claims, costs, damages, losses, expenses, obliga
tions,  liabilities,  recoveries,  suits,  causes  of action  and  deficiencies,
including  interest,  penalties and  reasonable  fees and expenses of attorneys,
consultants and experts (collectively, the "Damages") that the Buyer Indemnified
Parties  shall incur or suffer,  which  arise,  result from or relate to (i) any
breach by the  Shareholder of (or the failure of the Shareholder to perform) its
respective  representations,   warranties,   covenants  or  agreements  in  this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to Buyer by the Shareholder  under this Agreement or (ii) the Meier
Termination.

     4.2.  Indemnification by Buyer. In addition to any other remedies available
to the  Shareholder  under this Agreement,  or at law or in equity,  Buyer shall
indemnify,  defend and hold harmless the Shareholder against and with respect to
any and all Damages that such  indemnitees  shall incur or suffer,  which arise,
result from or relate to any breach of, or failure by Buyer to  perform,  any of
its representations, warranties, covenants or agreements in this Agreement or in
any schedule, certificate, exhibit or other instrument furnished or delivered to
the Shareholder by or on behalf of Buyer under this Agreement.

     4.3.  Indemnification  Procedure.  In  the  event  that  any  party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 4.1 or 4.2 of this Agreement,  such indemnified party shall give written
notice to the  indemnifying  party,  specifying  such claim,  and may thereafter
exercise any remedies  available to such party under this  Agreement;  provided,
however,  that the failure of any  indemnified  party to give notice as provided
herein shall not relieve the indemnifying party of any obligations hereunder, to
the extent the indemnifying party is not materially prejudiced thereby. Further,
promptly  after receipt by an indemnified  party  hereunder of written notice of
the  commencement  of any action or proceeding with respect to which a claim for
indemnification  may be  made  pursuant  to  Section  4.1 or  4.2  hereof,  such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying  party,  give written notice to the latter of the  commencement  of
such action;  provided,  however,  that the failure of any indemnified  party to
give notice as provided herein shall not relieve the  indemnifying  party of any
obligations  hereunder,  to the extent the indemnifying  party is not materially
prejudiced  thereby.  In case any such action is brought  against an indemnified
party, the indemnifying  party shall be entitled to participate in and to assume
the  defense  thereof,  jointly  with any  other  indemnifying  party  similarly
notified,  to the extent that it may wish, with counsel reasonably  satisfactory
to such indemnified  party, and after such notice from the indemnifying party to
such  indemnified  party of its election so to assume the defense  thereof,  the
indemnifying party shall not be liable to such indemnified party

C:\DOCUMENT\KENTSTAG.07
                                        9

     for any legal or other  expenses  subsequently  incurred  by the  latter in
connection with the defense thereof unless the indemnifying  party has failed to
assume the defense of such claim and to employ counsel  reasonably  satisfactory
to such indemnified  person. An indemnifying  party who elects not to assume the
defense of a claim  shall not be liable for the fees and  expenses  of more than
one  counsel in any single  jurisdiction  for all  parties  indemnified  by such
indemnifying party with respect to such claim or with respect to claims separate
but similar or related in the same jurisdiction  arising out of the same general
allegations.   Notwithstanding  any  of  the  foregoing  to  the  contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld or delayed.

                                  Miscellaneous

     5.1.   Survival  of   Representations,   Warranties  and   Covenants.   All
representations, warranties, covenants and agreements made by the parties hereto
shall survive indefinitely without limitation, notwithstanding any investigation
made by or on behalf of any of the parties hereto.  All statements  contained in
any certificate,  schedule,  exhibit or other instrument  delivered  pursuant to
this Agreement  shall be deemed to have been  representations  and warranties by
the  respective  party or  parties,  as the case may be, and shall also  survive
indefinitely  despite  any  investigation  made by any  party  hereto  or on its
behalf.

     5.2.  Entirety.  This  Agreement  embodies the entire  agreement  among the
parties  with respect to the subject  matter  hereof,  and all prior  agreements
between  the  parties  with  respect  thereto  are  hereby  superseded  in their
entirety.

     5.3.  Counterparts.  Any number of  counterparts  of this  Agreement may be
executed and each such counterpart shall be deemed to be an original instrument,
but all such counterparts together shall constitute but one instrument.

     5.4.  Notices  and  Waivers.  Any notice or waiver to be given to any party
hereto shall be in writing and shall be delivered by courier,  sent by facsimile
transmission  or first class  registered  or certified  mail,  postage  prepaid,

                        Schedule 2.1.9 - Title Exceptions


     1. The  Argentina  real  property  records do not  currently  show that the
Company  Subsidiary is the owner of the parcel of real  property  located in Las
Heres,  Argentina  and the two  parcels of real  property  located  in  Comodoro
Rivadavia,  Argentina (the "Company  Property") that valid purchase documents in
the possession of the Company Subsidiary  indicate it as owning. The Shareholder
represents  and  warrants  that (i) the Company  Subsidiary  is the owner in fee
simple of the Company Property (with no material Encumbrances thereon),  (ii) no
other party has claimed or can validly claim title to any portion of the Company
Property  and  (iii)  it has (or  will  cause  to be)  delivered  all  documents
necessary to file in the appropriate  real property  records to reflect that the
Company  Subsidiary  owns the  Company  Property  in fee  simple,  free from any
material Encumbrances.

     2.  Some of the  certificates  of  title  covering  the  thirty-seven  (37)
automobiles  and  light  pickup  trucks  owned by the  Company  Subsidiary  (the
"Company Vehicles") either do not properly reflect the Company Subsidiary as the
owner thereof or indicate that such  automobile is subject to a third part lien.
The Shareholder represents and warrants that Company Vehicles are owned outright
by the Company  Subsidiary  subject to no Encumbrances,  (ii) no other party has
claimed or can validly  claim title to any of the Company  Vehicles and (iii) it
has (or will cause to be)  delivered  to Buyer all  documents  necessary to file
with the  appropriate  governmental  agency to enable the Company  Subsidiary to
obtain a clear certificate of title to each Company Vehicle.

     (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

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

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.

entering  into the  Guarantee,  (b) the  Seller,  the Buyer and Key  Energy  are

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.

request  (including  any  request as may be required to be made by the Seller on
behalf of Oxy pursuant to the Oxy Purchase Agreement),  all at the sole cost and
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
(including as may be required under the Oxy Purchase Agreement), the Buyer shall

in the Oxy Purchase  Agreement) access at reasonable times during business hours
to the records of the Company.

claim or demand in connection with (a) any transaction  contemplated  under this
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,
stamp, documentary,  filing, recording, permit, license,  authorization or other
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.

REPRESENTATIONS,  WARRANTIES  AND  COVENANTS  OF  THE  SELLER  AND  THE  COMPANY
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

consolidation  or other  business  combination  involving the Company or for the
acquisition or purchase of any equity interest in, or a material  portion of the
assets of, the Company,  from any Person (other than the  transactions  with the
Buyer and Key Energy  contemplated by this Agreement) or (ii) participate in any
discussions or negotiations  regarding, or furnish to any Person, other than the

combination  or sale of equity  interests or assets  involving the Seller or any
Affiliate  (other than the Company)  shall not be prohibited  hereby nor require
notice  to the  Buyer  or Key  Energy  so  long  as such  proposals  permit  the
consummation of the transactions contemplated by this Agreement.

statement  pursuant to Rule 415 of the Securities  Act (the "Shelf  Registration
Statement") covering the offer and resale by the Seller of (i) the shares of Key
Energy Common Stock delivered to the Seller pursuant to Section 2.2(a)(ii),  and

initial filing thereof.


     (b)  Effectiveness of Shelf  Registration  Statement.  Key Energy agrees to
maintain  the Shelf  Registration  Statement  in effect for the  maximum  period
allowable under the regulations promulgated by the Commission;  provided that if
such  maximum  period is less than two years from the Closing  Date and if as of
the end of such maximum period not all of the Registered  Securities  registered
under the Shelf  Registration  Statement  have been sold or are capable of being
sold under Rule 144 of the  Securities  Act without  application  of the volume,
manner of sale or notice restrictions, then within 10 days after the end of such
maximum  period Key Energy shall file either a  post-effective  amendment to the
existing  Shelf  Registration  Statement or a new Shelf  Registration  Statement
covering  the offer and resale by the Seller of all  Registered  Securities  not
previously  sold,  and Key Energy will use its best efforts to cause the same to

compliance with any other governmental requirements.


     (d) Registration  Expenses. All expenses (except for any legal fees for the
Seller's  counsel)  relating to the  registration  of the Registered  Securities

with  governmental  requirements  of  preparing  and filing  any  post-effective
amendments or prospectus supplements required for the lawful distribution of the
Registered  Securities to the public in connection with such  registration) will
be paid by Key Energy.


     (e) Preparation;  Reasonable Investigation. Key Energy will give the Seller
the  opportunity  to participate  in the  preparation of the Shelf  Registration

access to its books and records and such  opportunities  to discuss the business
of Key Energy with its officers and the independent  public accountants who have
certified its financial  statements  as shall be  reasonably  necessary,  in the
Seller's judgment,  to conduct a reasonable  investigation within the meaning of
the Securities Act.


     (f) Transfer of Registration  Rights.  The registration  rights provided by
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

regulations of the Commission  thereunder,  as amended from time to time. If the
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

statement of a material  fact or omit to state any material  fact required to be
stated therein or necessary to make the statements therein not misleading,  and,
as promptly as practicable thereafter,  prepare and file with the Commission and
furnish a supplement  or amendment to such  prospectus  so that,  as  thereafter

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.

mutual written consent at any time prior to the Closing;


     (b) the Buyer or Key Energy may terminate  this Agreement by giving written
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
business days of such written notice (and provided further that the failure does
not result primarily from the Buyer or Key Energy breaching any  representation,
warranty or covenant applicable to them contained in this Agreement);


     (c) the Seller may terminate this Agreement by giving written notice to the
Buyer  and Key  Energy  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 6.2;  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
days of such  written  notice (and  provided  further  that the failure does not
result  primarily  from the Seller  breaching  any  representation,  warranty or
covenant applicable to it contained in this Agreement); or


     (d) the Buyer and Key Energy may elect to terminate  this  Agreement at any
time within two days  following the occurrence of an Industry  Material  Adverse
Event; provided,  however that irrevocable instructions are issued to the escrow
agent under the Escrow Agreement to transfer $5,000,000 in immediately available
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
damages,  and not as a penalty,  and shall be the Seller's  exclusive remedy for
such termination, notwithstanding the provisions of Section 7.2.


     7.2 Effect of Termination.  In the event of a termination of this Agreement
as a result  Section  7.1(b) or (c), at the sole  election  of the  nonbreaching

in cash from the breaching party or parties;  or (ii) the nonbreaching party may
exercise  any other right or remedy it may have at law, in equity or pursuant to
this  Agreement,  including  rights  to sue for  damages  or  required  specific
performance.  If the  nonbreaching  party elects the former remedy,  such remedy
shall be exclusive,  and shall constitute liquidated damages (and not a penalty)
for all claims the nonbreaching party may have with respect to such breach.


               ARTICLE 8. REMEDIES FOR BREACHES OF THIS AGREEMENT.


     8.1 Investigations; Survival of Representations,  Warranties and Covenants.
Each and every  representation,  warranty and covenant in this Agreement,  other
than the  representations  and  warranties  in  Section  3.13 and the  covenants
contained  in Sections  5.8,  5.9,  5.10,  5.11 and 5.14 and in Article 8, shall
expire,  and shall be terminated and extinguished,  by the second anniversary of
the Closing  Date and  thereafter  neither the Seller,  the Buyer nor Key Energy
shall be under any liability whatsoever with respect to any such representation,
warranty or covenant. The representations and warranties in Section 3.13 and the
covenants in Sections 5.8,  5.9,  5.10 and 5.11 shall expire upon  expiration of
the  applicable  statute of  limitation  periods  therefor and the  covenants in
Section 5.14 and Article 8 shall  continue  indefinitely  (unless any  provision
thereof is sooner terminated by its terms).

     8.2  Indemnification  Provisions for Benefit of the Buyer. In the event the
Seller breaches any of its  representations,  warranties and covenants contained
in this Agreement, if there is an applicable survival period pursuant to Section
8.1,  and  provided  that the Buyer  makes a written  claim for  indemnification
against the Seller pursuant to Section 9.7 within such survival period, then the
Seller agrees to indemnify,  defend and hold harmless the Buyer from and against
any Adverse  Consequences the Buyer may suffer through and after the date of the
claim for  indemnification  (including  any Adverse  Consequences  the Buyer may
suffer after the end of any applicable  survival period) resulting from, arising
out of,  relating  to, in the nature of or caused by the breach;  upon the terms
and conditions set forth herein.

8.3      Indemnification Provisions for Benefit of the Seller.

     (a)  In  the  event  the  Buyer  or  Key   Energy   breaches   any  of  its
representations,  warranties or covenants contained in this Agreement,  if there
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
and  after  the date of the claim for  indemnification  (including  any  Adverse
Consequences  the  Seller may suffer  after the end of any  applicable  survival
period) resulting from,  arising out of, relating to, in the nature of or caused
by the breach, upon the terms and subject to the conditions set forth herein.


     (b) Each of the Buyer and Key Energy agrees to  indemnify,  defend and hold
harmless  the Seller from and against the  entirety of any Adverse  Consequences
the Seller may suffer resulting from, arising out of, relating to, in the nature
of or caused by the  business,  operations,  assets,  properties,  employees  or
Employee Benefit Plans of the Company and that occurs after the Closing.


8.4      Matters Involving Third Parties.

     (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.


     (b) Any Indemnifying Party will have the right to assume the defense of the
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
given notice of the Third Party Claim; provided,  however, that the Indemnifying
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

                                 DRAFT:  11/11/97

                    AMENDMENT ONE TO STOCK PURCHASE AGREEMENT


     This  Amendment One to Stock  Purchase  Agreement,  dated as of October 10,
1997, amends the Stock Purchase Agreement (the "Stock Purchase Agreement") dated
as of July 31, 1997 among Nabors Acquisition Corp. IV (the "Seller"),  Key Rocky
Mountain,  Inc.  (the "Buyer") and Key Energy Group,  Inc.  ("Key  Energy") with
respect to Seller's sale of all the issued and outstanding capital stock of J.W.
Gibson Well Service  Company  (the  "Company").  Capitalized  terms used but not
defined herein are used as defined in the Stock Purchase Agreement.


     WHEREAS, the parties desire to amend the Stock Purchase Agreement to change
the Closing Date, to make certain other changes  related  thereto and to clarify
certain other conditions and provisions thereof; and


     WHEREAS, the parties are concurrently  amending the Operating Agreement and
Escrow  Agreement  to give effect to the  changes  made hereby and to enter into
certain other agreements;


     NOW,  THEREFORE,  in consideration of the above recitals and other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged,  the  Seller,  the  Buyer  and Key  Energy  agree to make  certain
amendments to the Stock Purchase Agreement as follows:

     1. From and after effectiveness of this Amendment and the amendments to the
Operating Agreement and the Escrow Agreement, the terms "Agreement",  "Operating
Agreement" and "Escrow  Agreement" used in the Stock Purchase Agreement shall be
deemed to refer to each such  agreement  as amended on the date hereof or as may
be amended from time to time.  2.  Section 2.3 is hereby  amended to read in its
entirety as follows:

     2.3 Additional Purchase Price Adjustments and Procedures.ts and Procedures


     (a) On the date  hereof,  the Buyer has  delivered  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 have included 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 from the date hereof,  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) (i) 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.  If the Final  Determination  Date  occurs  at least  three
business  days prior to the Closing  Date,  and the Seller is required to make a
payment  to the Buyer in  accordance  with the first  sentence  of this  Section
2.3(b)(i),  the  additional  amount due shall be disbursed to the Buyer from the
funds deposited with the escrow agent under the Escrow Agreement.


     (ii) 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.  If the Final  Determination  Date  occurs  at least  three
business  days prior to the  Closing  Date,  and the Buyer is required to make a
payment to the Seller in  accordance  with the third  sentence  of this  Section
2.3(b),  the Buyer shall deposit the additional amount due with the escrow agent
under the Escrow Agreement.


     (iii) Each of the Seller,  the Buyer and Key Energy  agrees to provide such
notices as may be required under the Escrow  Agreement to carry out the purposes
and intents of this Section 2.3(b).


     (c) The July 31 Balance Sheet shall have been  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.  Each party agrees to use reasonable
efforts to arrive at a final  determination  of the Purchase Price adjustment on
or before the Closing Date.


     (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."

     3.  Section  2.4,  clause  (a) of the Stock  Purchase  Agreement  is hereby
amended to read in its entirety as follows:  "(a) a date between January 2, 1998
and  January 15, 1998 or".  4.  Sections  7.1 (b) and (c) are hereby  amended by
changing the date therein from "December 31, 1997" to "January 31, 1998". 5. The
Loan  Agreement  referenced  in  Schedule  3.6 to the  Disclosure  Schedule  was
terminated on September 10, 1997,  and UCC-3  termination  statements  have been
filed with respect thereto,  all as evidenced on Attachment 1 hereto. The Seller
represents  and  warrants  to  the  Buyer  and  Key  Energy  that  there  are no
encumbrances arising under such Loan Agreement on the Company or its property at
the date hereof and agrees that it will perform all acts reasonably requested by
the  Buyer  to  remove  any  such   encumbrances  in  the  event  the  foregoing
representation  is not  true.  The  execution  and  delivery  of this  Amendment
satisfies  the  closing  condition  set  forth in  Section  6.1(i)  of the Stock
Purchase Agreement. 6. The parties hereby agree that, notwithstanding footnote 2
to Schedule 3.14 of the Disclosure  Schedule,  as promptly as practicable  after
the date hereof an  affiliate  of the Seller will convey to the Company the yard
in Gillette,  Wyoming  referenced  in such Schedule  3.14,  and the Company will
convey  to an  affiliate  of the  Seller  the  yard  in  Rock  Springs,  Wyoming
referenced in such Schedule 3.14. Such conveyances will be in substantially  the
forms attached hereto as Attachment 2.



     IN WITNESS WHEREOF,  the undersigned have executed this Amendment as of the
date first written above.

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."

     3.  Section  2.4,  clause  (a) of the Stock  Purchase  Agreement  is hereby
amended to read in its entirety as follows:  "(a) a date between January 2, 1998
and  January 15, 1998 or".  4.  Sections  7.1 (b) and (c) are hereby  amended by
changing the date therein from "December 31, 1997" to "January 31, 1998". 5. The
Loan  Agreement  referenced  in  Schedule  3.6 to the  Disclosure  Schedule  was
terminated on September 10, 1997,  and UCC-3  termination  statements  have been
filed with respect thereto,  all as evidenced on Attachment 1 hereto. The Seller
represents  and  warrants  to  the  Buyer  and  Key  Energy  that  there  are no
encumbrances arising under such Loan Agreement on the Company or its property at
the date hereof and agrees that it will perform all acts reasonably requested by
the  Buyer  to  remove  any  such   encumbrances  in  the  event  the  foregoing
representation  is not  true.  The  execution  and  delivery  of this  Amendment
satisfies  the  closing  condition  set  forth in  Section  6.1(i)  of the Stock
Purchase Agreement. 6. The parties hereby agree that, notwithstanding footnote 2
to Schedule 3.14 of the Disclosure  Schedule,  as promptly as practicable  after
the date hereof an  affiliate  of the Seller will convey to the Company the yard
in Gillette,  Wyoming  referenced  in such Schedule  3.14,  and the Company will
convey  to an  affiliate  of the  Seller  the  yard  in  Rock  Springs,  Wyoming
referenced in such Schedule 3.14. Such conveyances will be in substantially  the
forms attached hereto as Attachment 2.



     IN WITNESS WHEREOF,  the undersigned have executed this Amendment as of the
date first written above.

Shareholder agree that for a period of 60 months following the date hereof, such
party  will  not (and  will  cause  Douglas  S.  Morris  not  to),  directly  or

investor  in as much as 5% of any  security of any class of any  corporation  or

restrictive in any court  proceeding,  the court may reduce such restrictions to
those  which  it deems  reasonable  under  the  circumstances.  The  obligations
expressed in this Section 3.1 are in addition to any other  obligations that the
Seller  and the  Shareholder  may have under the laws of any state  requiring  a

certificate,  exhibit or other instrument furnished or delivered to Buyer by the

     IV.3 Indemnification  Procedure. If any party hereto discovers or otherwise
becomes  aware of an  indemnification  claim arising under Section 4.1 or 4.2 of
this  Agreement,  such  indemnified  party  shall  give  written  notice  to the
indemnifying  party,  specifying  such claim,  and may  thereafter  exercise any
remedies available to such party under this Agreement;  provided,  however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified  party hereunder of written notice of the commencement
of any action or  proceeding  with respect to which a claim for  indemnification
may be made pursuant to this Article 4, such indemnified party shall, if a claim
in respect thereof is to be made against any  indemnifying  party,  give written
notice to the latter of the commencement of such action; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is  brought  against an  indemnified  party,  the  indemnifying  party  shall be
entitled to participate in and to assume the defense  thereof,  jointly with any
other  indemnifying  party similarly  notified,  to the extent that it may wish,
with counsel  reasonably  satisfactory to such indemnified party, and after such
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense  thereof,  the  indemnifying  party shall not be liable to
such indemnified party for any legal or other expenses  subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying  party
has failed to assume the defense of such claim and to employ counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld or delayed.

business  and is in good  standing  as a foreign  corporation  authorized  to do
business in all  jurisdictions in which the character of the properties owned or
the nature of the  business  conducted  by it would make such  qualification  or
licensing  necessary,  except  where the failure to be so  qualified or licensed

manner as to give rise to any valid claim against any of the parties  hereto for
any brokerage commission, finder=s fee or any similar payments.

     2.2.5. Buyer=s Assumption of Company  Liabilities.  Buyer hereby agrees and
promises to assume any and all obligations and liabilities that are reflected on

     4.1. Indemnification by the Shareholder.  In addition to any other remedies
available to Buyer under this Agreement, or at law or in equity, the Shareholder
shall  indemnify,  defend  and  hold  harmless  the  Company,  Buyer  and  their
affiliates  and their  respective  officers,  directors,  employees,  agents and
stockholders (collectively,  the ABuyer Indemnified Parties@),  against and with
respect to any and all claims, costs, damages,  losses,  expenses,  obligations,
liabilities,  recoveries,  suits,  causes of action and deficiencies,  including
interest,  penalties and reasonable fees and expenses of attorneys,  consultants
and experts  (collectively,  the ADamages@) that the Buyer  Indemnified  Parties
shall incur or suffer,  which arise,  result from or relate to any breach by the
Shareholder   of  (or  the  failure  of  the   Shareholder   to   perform)   his
representations, warranties, covenants or agreements in this Agreement or in any
schedule,  certificate,  exhibit or other  instrument  furnished or delivered to
Buyer by the Shareholder under this Agreement.

     4.2.  Indemnification by Buyer. In addition to any other remedies available
to the  Shareholder  under this Agreement,  or at law or in equity,  Buyer shall
indemnify,  defend and hold harmless the Shareholder against and with respect to
any and all Damages that Shareholder shall incur or suffer,  which arise, result
from or relate to any  breach of, or  failure  by Buyer to  perform,  any of its
representations, warranties, covenants or agreements in this Agreement or in any
schedule, certificate, exhibit or other instrument furnished or delivered to the
Shareholder by or on behalf of Buyer under this Agreement.

     4.3.  Indemnification  Procedure.  In  the  event  that  any  party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 4.1 or 4.2 of this Agreement,  such indemnified party shall give written
notice to the  indemnifying  party,  specifying  such claim,  and may thereafter
exercise any remedies  available to such party under this  Agreement;  provided,
however,  that the failure of any  indemnified  party to give notice as provided
herein shall not relieve the indemnifying party of any obligations hereunder, to
the extent the indemnifying party is not materially prejudiced thereby. Further,
promptly  after receipt by an indemnified  party  hereunder of written notice of
the  commencement  of any action or proceeding with respect to which a claim for
indemnification  may be  made  pursuant  to  Section  4.1 or  4.2  hereof,  such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying  party,  give written notice to the latter of the  commencement  of
such action;  provided,  however,  that the failure of any indemnified  party to
give notice as provided herein shall not relieve the  indemnifying  party of any
obligations  hereunder,  to the extent the indemnifying  party is not materially
prejudiced  thereby.  In case any such action is brought  against an indemnified
party, the indemnifying  party shall be entitled to participate in and to assume
the  defense  thereof,  jointly  with any  other  indemnifying  party  similarly
notified,  to the extent that it may wish, with counsel reasonably  satisfactory
to such indemnified  party, and after such notice from the indemnifying party to
such  indemnified  party of its election so to assume the defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in the same jurisdiction arising out of the same general allegations. Subject to
the following,  the indemnified party will be entitled to select its own counsel
and assume the  defense of any  action  brought  against it if the  indemnifying
party fails to select counsel reasonably  satisfactory to the indemnified party,
the  expenses  of  such  defense  to be  paid  by the  indemnifying  party.  The
indemnified  party is obligated to specify the basis of any  determination  that
counsel  selected  by  the  indemnifying  party  is  unsatisfactory  before  the
indemnifying  party shall be liable for attorney fees of counsel selected by the
indemnified  party.  The basis must be reasonable  and well grounded  before the
indemnifying  party shall be liable for the expenses of counsel  selected by the
indemnifying party. No indemnifying party shall consent to entry of any judgment
or enter into any settlement  with respect to a claim without the consent of the
indemnified party, which consent shall not be unreasonably  withheld,  or unless
such judgment or settlement includes as an unconditional term thereof the giving
by the  claimant or plaintiff  to such  indemnified  party of a release from all
liability  with respect to such claim.  No  indemnified  party shall  consent to
entry of any judgment or enter into any  settlement  of any such action  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld  or  delayed,  unless the  indemnifying  party has refused to provide a
defense  against  such claim or action.  Likewise,  no  indemnified  party shall
consent to entry of  judgment or enter into any  settlement  of such claim where
the  indemnifying  party has refused to provide a defense  against such claim or
action until the indemnified  party has given the  indemnifying  party notice of
the terms of the judgment or settlement  and an  opportunity  to continue with a
defense if the judgment or settlement is unsatisfactory.

     1 ARTICLE

                         Representations and Warranties

     1.1.  Representations  and  Warranties  of the  Shareholders.  Each  of the
Shareholders jointly and severally represents and warrants to Buyer as follows:

     1.1.1.  Organization  and  Standing.  The  Company  is a  corporation  duly
organized,  validly existing and in good standing under the laws of the state of
Texas, has full requisite corporate power and authority to carry on its business
as it is currently  conducted,  and to own and operate the properties  currently
owned and  operated by it, and is duly  qualified or licensed to do business and
is in good  standing as a foreign  corporation  authorized to do business in all
jurisdictions  in which the character of the  properties  owned or the nature of
the  business  conducted  by it  would  make  such  qualification  or  licensing
necessary,  except where the failure to be so  qualified  or licensed  would not
have a  material  adverse  effect  on its  financial  condition,  properties  or
business.

     1.1.1.  Agreement  Authorized and its Effect on Other Obligations.  Each of
the  Shareholders  is a resident of Hockley County,  Texas,  above the age of 18
years,  and has the legal  capacity and  requisite  power and authority to enter
into, and perform his or her obligations under this Agreement. This Agreement is
a valid and binding obligation of each of the Shareholders  enforceable  against
each of the Shareholders  (subject to normal equitable principles) in accordance
with  its  terms,  except  as  enforceability  may  be  limited  by  bankruptcy,
insolvency,  reorganization,  debtor relief or similar laws affecting the rights
of  creditors  generally.  The  execution,  delivery  and  performance  of  this
Agreement by the Shareholders will not conflict with or result in a violation or
breach of any term or  provision  of,  nor  constitute  a default  under (i) the
Articles  of  Incorporation  or Bylaws of the  Company  or (ii) any  obligation,
indenture,  mortgage, deed of trust, lease, contract or other agreement to which
the Company or any of the Shareholders is a party or by which the Company or any
of the Shareholders or their respective properties are bound.

     1.1.1.  Capitalization.   The  authorized  capitalization  of  the  Company
consists of 100,000  shares of Company  Common Stock,  of which,  as of the date
hereof,  100,000 shares were issued and outstanding and held beneficially and of
record by the  Shareholders.  On the date hereof,  the Company does not have any
outstanding options, warrants, calls or commitments of any character relating to
any of its  authorized  but  unissued  shares of capital  stock.  All issued and
outstanding  shares of Company Common Stock are validly  issued,  fully paid and
non-assessable and are not subject to preemptive rights. None of the outstanding
shares of Company Common Stock is subject to any voting trusts, voting agreement
or other agreement or understanding  with respect to the voting thereof,  nor is
any proxy in existence with respect thereto.

     1.1.1.  Ownership of the Company  Shares.  The  Shareholders  hold good and
valid title to all of the Company  Shares,  free and clear of all  Encumbrances.
The  Shareholders  possess full authority and legal right to sell,  transfer and
assign to Buyer the Company  Shares,  free and clear of all  Encumbrances.  Upon
transfer to Buyer by the Shareholders of the Company Shares,  Buyer will own the
Company Shares free and clear of all  Encumbrances.  There are no claims pending
or, to the knowledge of any of the Shareholders, threatened, against the Company
or any of the  Shareholders  that concern or affect title to the Company Shares,
or that seek to compel the issuance of capital stock or other  securities of the
Company.

     1.1.1.  No  Subsidiaries.  There  is  no  corporation,  partnership,  joint
venture,  business  trust or other  legal  entity in which the  Company,  either
directly  or  indirectly  through  one or more  intermediaries,  owns  or  holds
beneficial or record ownership of at least a majority of the outstanding  voting
securities.

     1.1.1.  Financial Statements.  The Company has delivered to Buyer copies of
the Company's  unaudited  balance  sheet (the "7/31 Balance  Sheet") and related
statements  of income,  copies of which are  attached  hereto as Schedule  2.1.6
(collectively, the "7/31 Financial Statements"), as, at and for the seven months
ended July 31, 1997 (the "Balance Sheet Date").  The 7/31  Financial  Statements
are  complete in all material  respects  except that the  Company's  accrual for
Federal  income taxes has been based solely on  quarterly  income tax  estimates
which are based on the  Company's  total income tax paid for the  calendar  year
1996. The Shareholders  estimate that according to Generally Accepted Accounting
Principles (GAAP), the income tax accrual should reflect an additional $390,000.
With the exception of the income taxes which have not been properly accrued, the
7/31 Financial Statements presents fairly the financial condition of the Company
as and at the dates and for the  periods  indicated.  Except for the  inadequate
accrual for income taxes (as noted above),  the 7/31 Financial  Statements  have
been  prepared  in  accordance  with GAAP  applied on a  consistent  basis.  The
accounts  receivable  reflected  in the 7/31 Balance  Sheet,  or which have been
thereafter  acquired by the Company,  have been collected or are  collectible at
the aggregate recorded amounts thereof. The inventories of the Company reflected
in the 7/31 Balance Sheet, or which have thereafter been acquired by it, consist
of items of a quality  usable and salable in the normal  course of the Company's

directly with the Company and the  Shareholders  and their counsel,  without the

manner as to give rise to any valid claim against any of the parties  hereto for
any brokerage commission, finder's fee or any similar payments.

                              Additional Agreements

     1.1.  Noncompetition.  Except as  otherwise  consented  to or  approved  in
writing by Buyer, each of the Shareholders agrees that for a period of 60 months
from the date hereof, such Shareholder will not, directly or indirectly,  acting
alone or as a member of a  partnership  or as an  officer,  director,  employee,
consultant,  representative,  holder  of,  or  investor  in as much as 5% of any
security of any class of any  corporation or other business entity (i) engage in
competition with the business or businesses  conducted by the Company,  Buyer or
any  affiliate  of Buyer on the date  hereof,  or in any  service  business  the
services  of which  are  provided  and  marketed  by the  Company,  Buyer or any
affiliate of Buyer on the date hereof in any state of the United States,  or any
foreign country in which the Company,  Buyer or any affiliate of Buyer transacts
business on the date  hereof  (provided,  however,  the  foregoing  shall not be
construed as preventing  Shareholder  Lynn E. Waters from performing any type of
activity in the oil and gas industry, including being an employee, consultant or
other  representative  of any other  entity,  regardless  of whether said entity
competes  against the Company,  Buyer or any affiliate of Buyer, so long as Lynn
E.  Waters  does not own,  vote or control as much as five  percent  (5%) of any
security  of any  class of said  business  entity);  (ii)  request  any  present
customers  or  suppliers  of the  Company,  Buyer or any  affiliate  of Buyer to
curtail or cancel their  business  with the Company,  Buyer or any  affiliate of
Buyer; (iii) disclose to any person, firm or corporation any trade, technical or
technological  secrets of the  Company,  Buyer or any  affiliate of Buyer or any
details of their  organization  or  business  affairs or (iv) induce or actively
attempt to  influence  any employee of the  Company,  Buyer or any  affiliate of
Buyer to  terminate  his  employment.  Each of the  Shareholders  agrees that if
either the length of time or geographical  area set forth in this Section 3.1 is
deemed  too  restrictive  in any court  proceeding,  the court may  reduce  such
restrictions to those which it deems  reasonable  under the  circumstances.  The
obligations  expressed  in  this  Section  3.1  are in  addition  to  any  other
obligations that the Shareholders may have under the laws of the states in which
they do business  requiring an employee of a business or a shareholder who sells
his stock in a corporation  (including a  disposition  in a merger) to limit his
activities  so that the goodwill  and business  relations of his employer and of
the corporation whose stock he has sold (and any successor corporation) will not
be materially impaired. Each of the Shareholders further agrees and acknowledges
that the Company,  Buyer and its  affiliates do not have any adequate  remedy at
law for the breach or threatened  breach by such  Shareholder  of this covenant,
and agree that the Company,  Buyer or any affiliate of Buyer may, in addition to
the other remedies which may be available to it hereunder, file a suit in equity
to enjoin  such  Shareholder  from  such  breach or  threatened  breach.  If any
provisions of this Section 3.1 are held to be invalid or against  public policy,
the remaining provisions shall not be affected thereby. Each of the Shareholders
acknowledges that the covenants set forth in this Section 3.1 are being executed
and delivered by such  Shareholder  in  consideration  of the covenants of Buyer
contained  in this  Agreement,  and for other good and  valuable  consideration,
receipt of which is hereby acknowledged.

     1.1. Employment Agreement. The parties hereto acknowledge the execution and
delivery  of an  employment  agreement  between  Joe Dee Brooks and the  Company
concurrently herewith.

     1.1.  Further  Assurances.  From time to time, as and when requested by any
party hereto,  any other party hereto shall execute and deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to
effectuate the transactions contemplated hereby.

     3.4.  Company's  Stock Not  Registered.  The  Company is a  privately  held
corporation  and  Buyer  acknowledges  such.  The  Company's  stock has not been
registered under the Securities Act of 1933, as Amended (the "Act") or under any
applicable state securities  laws, and the stock,  therefore,  cannot be offered
for  sale,  sold,  transferred,  pledged  or  otherwise  hypothecated  except in
accordance  with the  registration  requirements of the Act and other such state
laws as may be applicable.  Buyer acknowledges that Seller has made available to
it  such  information  and  documents,  and  that  Buyer  understands  the  risk
associated  with  ownership of the capital  stock of the  Company,  and Buyer is
capable of bearing the financial risk associated therewith. The Company's shares
and the  dealings  with Buyer are  proceeding  in  reliance on  exceptions  from
registration or qualification requirements pursuant to state law.

     3.5.  Opinion  of  Shareholders'  Counsel.  Buyer  shall  have  received  a
favorable opinion, dated as of the Closing Date, from Bradford L. Moore, counsel
to the Shareholders,  in form and substance satisfactory to Buyer, to the effect
that (i) the Company  has been duly  incorporated  and is validly  existing as a
corporation and is in good standing under the laws of the State of Texas;  (ii),
the Company has fully  requisite  corporate  power and authority to carry on its
business as it is  currently  conducted  and to own and  operate the  properties
currently  used and operated by it, and is duly  qualified to do business and is
in good standing as a foreign  corporation  and authorized to do business in the
State of New Mexico;  (iii) all outstanding shares of the Company's common stock
have  been  validly  issued  and are  fully  paid and  non-assessable;  (iv) the
Shareholders  hold good and valid  title to all of the  Company  shares free and
clear of all  Encumbrances;  and (v) this  Agreement  has been duly executed and
delivered  by,  and  is  the  legal,   valid  and  binding   obligation  of  the
Shareholders, and is enforceable against the Shareholders in accordance with its
terms,  except as the enforceability may be limited by (a) equitable  principles
of  general  applicability  or  (b)  bankruptcy,   insolvency,   reorganization,
fraudulent  conveyance  or  similar  laws  affecting  the  rights  of  creditors
generally. In rendering such opinion, such counsel may rely upon certificates of
public  officials and of officers of Seller or the Shareholders as to matters of
fact.

     3.6.  Opinion  of  Buyer's  Counsel.  Shareholders  shall  have  received a
favorable opinion,  dated as of the Closing Date, from Lynch,  Chappell & Alsup,
counsel for Buyer, in form and substance  satisfactory to the  Shareholders,  to
the effect that (i) Buyer has been duly  incorporated and is validly existing as
a corporation  in good standing  under the laws of the State of Delaware and has
full requisite  corporate  power and authority to carry on its business as it is
currently  conducted and to own and operate the properties  currently  owned and
operated by it and is duly  qualified  or licensed to do business and is in good
standing  as a foreign  corporation  authorized  to do  business in the State of
Texas; (ii) all corporate  proceedings required to be taken by or on the part of
Buyer to authorize the execution of this Agreement and the implementation of the
transactions  contemplated hereby have been taken; (iii) this Agreement has been
duly executed and delivered by, and is the legal,  valid and binding  obligation
of Buyer and is enforceable  against Buyer in accordance with its terms,  except
as the  enforceability  may be limited by (a)  equitable  principles  of general
applicability  or  (b)  bankruptcy,   insolvency,   reorganization,   fraudulent
conveyance  or similar  laws  affecting  the rights of creditors  generally.  In
rendering  such  opinion,  such  counsel  may rely upon  certificates  of public
officials and of officers of Buyer as to matters of fact.

     3.7.  Fees and  Expenses.  Except as otherwise  expressly  provided in this
Agreement,  all fees and  expenses,  including  fees and  expenses  of  counsel,
financial  advisors and  accountants  incurred in connection with this Agreement
and the  transactions  contemplated  hereby shall be paid by the party incurring
such fee or expense by or on the date hereof.

                                 Indemnification

     1.1. Indemnification by the Shareholders. In addition to any other remedies
available  to Buyer under this  Agreement,  or at law or in equity,  each of the
Shareholders shall jointly and severally indemnify, defend and hold harmless the
Company,  Buyer and their affiliates and their respective  officers,  directors,
employees,  agents  and  stockholders  (collectively,   the  "Buyer  Indemnified
Parties"),  against  and with  respect to any and all  claims,  costs,  damages,
losses, expenses, obligations,  liabilities, recoveries, suits, causes of action
and deficiencies, including interest, penalties and reasonable fees and expenses
of attorneys, consultants and experts (collectively, the "Damages") in excess of
$150,000 in the  aggregate  that the Buyer  Indemnified  Parties  shall incur or
suffer,  which  arise,  result  from or relate  to (i) any  breach by any of the
Shareholders  of (or the failure of any of the  Shareholders  to perform)  their
respective  representations,   warranties,   covenants  or  agreements  in  this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to Buyer by any of the Shareholders under this Agreement,  (ii) the
Company's  ownership  and/or  operation of those  properties  distributed to the
Shareholders  prior to the date hereof  referred to in Schedule  2.1.10  hereto,
(iii) the promissory  note  represented by the "Notes Payable - SKROS" line item
on the 7/31 Balance Sheet assumed by the Shareholders  prior to the date hereof;
provided,   however,  that  (iv)  the  Shareholders'  aggregate  obligations  to
indemnify  Buyer and the other parties  identified  above shall never exceed the
aggregate sum of  $15,000,000.00;  (v) the Shareholders shall not be required to
so  indemnify,  defend  and hold  harmless  Buyer and its  officers,  directors,
employees,  agents and  stockholders,  against  and with  respect to any damages
incurred  as a  result  of a  breach  by  either  of the  Shareholders  of their
respective representations and warranties of this Agreement, or in any schedule,
certificate,  exhibit or other instrument furnished or delivered to Buyer by any
of the  Shareholders  under  this  Agreement  for which  Buyer  fails to provide
written notice of a claim for such damages to the  Shareholders on or before the
expiration  of the survival  period (as  specified in Section 5.1 hereof) of the
specific  representation or warranty alleged to have been breached;  (vi) to the
extent  the  Buyer has  actually  recovered  damages  from a  collateral  source
including,  but not limited to, a third party or insurance  coverage,  for which
Buyer is  indemnified  by the  Shareholders  pursuant to this Section 4.1,  then
Buyer agrees not to enforce its right to indemnification  under this Section 4.1
(and the  Buyer  agrees  that it  will,  to the  extent  it can  legally  do so,
subrogate its right to collect any such damages from a collateral  source to the
Shareholders to the extent the Shareholders  have paid such  indemnification  to
the Buyer); and (vii) Buyer agrees it will not seek  indemnification  under this
Section  4.1  for  any  environmental  remedial  work  on any  of the  Company's
properties  unless the Company (or Buyer) is required to perform  such work by a
third party or by a governmental entity or agency.

     1.1.  Indemnification by Buyer. In addition to any other remedies available
to the Shareholders  under this Agreement,  or at law or in equity,  Buyer shall
indemnify,  defend and hold harmless each of the  Shareholders  against and with
respect to any and all Damages in excess of $150,000 in the aggregate, that such
indemnitees  shall incur or suffer,  which  arise,  result from or relate to any
breach  of,  or  failure  by  Buyer  to  perform,  any of  its  representations,
warranties,  covenants  or  agreements  in this  Agreement  or in any  schedule,
certificate,  exhibit or other  instrument  furnished or delivered to any of the
Shareholders by or on behalf of Buyer under this Agreement;  provided,  however,
that (i) Buyer's aggregate  obligation to indemnify the Shareholders shall never
exceed  the sum of  $15,000,000.00;  (ii)  Buyer  shall  not be  required  to so
indemnify,  defend and hold harmless the  Shareholders  and their  employees and
agents against and with respect to any damages  incurred as a result of a breach
by Buyer of any of its representations  and warranties in this Agreement,  or in
any schedule, certificate, exhibit or other instrument furnished or delivered to
the Shareholders by Buyer under this Agreement for which the  Shareholders  fail
to provide  written notice of a claim for such damages to Buyer on or before the
expiration of the survival period (as is specified in Section 5.1 hereof) of the
specific representations or warranty alleged to have been breached; and (iii) to
the extent the Shareholders  have actually  recovered  damages from a collateral
source,  including,  but not limited to a third party or insurance  coverage for
which the  Shareholders  are  indemnified by Buyer pursuant to this Section 4.2,
then the Shareholders agree not to enforce their right to indemnification  under
this Section 4.2 (and the Shareholders  agree that they will, to the extent they
can legally do so,  subrogate  their  rights to collect any such  damages from a
collateral  source  to  the  Buyer  to  the  extent  the  Buyer  has  paid  such
indemnification to the Shareholders.

     1.1.  Indemnification  Procedure.  In  the  event  that  any  party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Article 4 of this Agreement, such indemnified party shall give written notice to
the indemnifying  party,  specifying such claim, and may thereafter exercise any
remedies available to such party under this Agreement;  provided,  however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified  party hereunder of written notice of the commencement
of any action or  proceeding  with respect to which a claim for  indemnification
may be made  pursuant to  Sections  4.1 or 4.2 hereof,  such  indemnified  party
shall,  if a claim in respect  thereof is to be made  against  any  indemnifying
party,  give written  notice to the latter of the  commencement  of such action;
provided,  however,  that the failure of any indemnified party to give notice as
provided  herein  shall not relieve the  indemnifying  party of any  obligations
hereunder,  to the extent the  indemnifying  party is not materially  prejudiced
thereby.  In case any such action is brought against an indemnified  party,  the
indemnifying party shall be entitled to participate in and to assume the defense
thereof,  jointly with any other indemnifying party similarly  notified,  to the
extent  that  it  may  wish,  with  counsel  reasonably   satisfactory  to  such
indemnified  party,  and after such notice from the  indemnifying  party to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in  the  same  jurisdiction   arising  out  of  the  same  general  allegations.
Notwithstanding any of the foregoing to the contrary, the indemnified party will
be  entitled  to select its own  counsel  and  assume the  defense of any action
brought against it if the indemnifying  party fails to select counsel reasonably
satisfactory to the indemnified  party,  the expenses of such defense to be paid
by the indemnifying  party. No indemnifying  party shall consent to entry of any
judgment  or enter  into any  settlement  with  respect to a claim  without  the
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld,  or unless such  judgment or settlement  includes as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability with respect to such claim. No indemnified party
shall consent to entry of any judgment or enter into any  settlement of any such
action, the defense of which has been assumed by an indemnifying party,  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld or delayed.

exercise of a conversion right under Article 10, or for the payment of principal
or interest on the Securities, and will notify the Trustee of any default by the

Transfer Restricted Security; and

     (B) any such Transfer Restricted Security  represented by a Global Security

transfer  being  subject  only to the  provisions  of  Section  2.6(c)  hereof);
provided,  however,  that with  respect  to any  request  for an  exchange  of a
Transfer  Restricted  Security that is  represented  by a Global  Security for a
Definitive  Security  that  does not bear a  legend,  which  request  is made in
reliance  upon Rule 144 or 145, the Holder  thereof  shall certify in writing to
the  Registrar or  co-Registrar  and shall  provide an Opinion of Counsel to the
Registrar or  co-Registrar  that such request is being made pursuant to Rule 144
or 145.

     (f)  Cancellation  or  Adjustment of Global  Security.  At such time as all
beneficial  interests  in a Global  Security  have  either  been  exchanged  for
Definitive Securities,  redeemed,  repurchased or canceled, such Global Security
shall be returned to or retained and canceled by the Trustee. At any time before
such cancellation,  if any beneficial interest in a Global Security is exchanged
for Definitive  Securities,  redeemed,  repurchased  or canceled,  the principal
amount of Securities represented by such Global Security shall be reduced and an
adjustment shall be made on the books and records of, or an endorsement shall be
made on such Global Security by, the Trustee or the Securities Custodian, at the
direction of the Trustee,  to reflect the reduction,  all in accordance with the
standing  instructions  and procedures  existing  between the Depository and the
Securities Custodian.

     (g)  Obligations  with respect to  Transfers  and  Exchanges of  Definitive
Securities.

     (i) To permit  registrations of transfers and exchanges,  the Company shall
execute and the Trustee  shall  authenticate  Definitive  Securities  and Global
Securities at the Registrar's or co-Registrar's request.

     (ii) No service  charge shall be made to a Holder for any  registration  of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any  transfer tax or similar  governmental  charge  payable in  connection
therewith  (other than any such transfer  taxes or similar  governmental  charge
payable  upon  exchanges  or transfers  pursuant to Sections  2.10,  3.6 and 9.5
hereof).

     (iii) The Registrar or  co-Registrar  shall not be required to register the
transfer or exchange of any Definitive Security selected for redemption in whole
or in part,  except the  unredeemed  portion of any  Definitive  Security  being
redeemed in part.

     (iv) All  Definitive  Securities  and  Global  Securities  issued  upon any
registration  of  transfer  or  exchange  of  Definitive  Securities  or  Global
Securities  shall be the valid  obligations of the Company,  evidencing the same
debt,  and entitled to the same benefits  under this Indenture as the Definitive
Securities or Global  Securities  surrendered upon such registration of transfer
or exchange.

                                       18




     (v) The Company shall not be required:

     (A) to issue,  register  the  transfer of or exchange  Securities  during a
period  beginning  at the  opening  of  business  15 days  before the day of any
selection of Securities for redemption under Section 3.2 and ending at the close
of business of the day of selection, or

     (B) to register  the  transfer or exchange of any  Security so selected for
redemption in whole or in part,  except the  unredeemed  portion of any Security
being redeemed in part.

     (vi) Before due presentment  for  registration of transfer of any Security,
the  Trustee,  any Agent and the  Company may deem and treat the Person in whose
name any Security is registered  as the absolute  owner of such Security for the
purpose of receiving  payment of principal of and interest and premium,  if any,
on such  Security  and for all other  purposes  whatsoever,  whether or not such
Security is overdue,  and neither the Trustee,  any Agent, nor the Company shall
be affected by notice to the contrary.

     Section 2.7 Replacement Securities.

     If any mutilated Security is surrendered to the Trustee or the Company,  or
the Trustee receives  evidence to its  satisfaction of the destruction,  loss or
theft of any Security, the Company shall issue and the Trustee, upon the written
order of the Company signed by two Officers of the Company, shall authenticate a
replacement   Security  if  the  Trustee's   requirements  for  replacements  of
Securities are met. If required by the Trustee or the Company, an indemnity bond
must be supplied by the Holder that is sufficient in the judgment of the Trustee
and  the  Company  to  protect  the  Company,  the  Trustee,  any  Agent  or any
authenticating  agent from any loss that any of them may suffer if a Security is
replaced. The Company and the Trustee may charge for their expenses in replacing
a Security.

     Every replacement Security is an additional obligation of the Company.

     Section 2.8 Outstanding Securities.

     The Securities outstanding at any time are all the Securities authenticated
by the  Trustee  except for those  canceled  by it,  those  delivered  to it for
cancellation,  and  those  reductions  in the  interests  in a  Global  Security
effected by the Trustee  hereunder,  and those described in this  Section 2.8 as
not outstanding.

     If a Security is replaced  pursuant to Section 2.7 hereof,  it ceases to be
outstanding  unless  the  Trustee  receives  proof  satisfactory  to it that the
replaced Security is held by a bona fide purchaser.

     If the principal  amount of any Security is  considered  paid under Section
4.1 hereof, it ceases to be outstanding, and interest on it ceases to accrue.


053113\1008\02764\979QGT85.OTH
                                       19



     Except as set forth in Section 2.9 hereof,  a Security does not cease to be
outstanding  because  the  Company  or an  Affiliate  of the  Company  holds the
Security.

     Section 2.9 Treasury Securities.

     In  determining  whether the Holders of the  required  principal  amount of
Securities have concurred in any direction,  waiver or consent, Securities owned
by the  Company or any  Affiliate  of the  Company  (whether  directly  or by or
through the Depository)  shall be considered as though not  outstanding,  except
that for  purposes of  determining  whether the Trustee  shall be  protected  in
relying  on any such  direction,  waiver  or  consent,  only  Securities  that a
Responsible Officer knows to be so owned shall be so considered.

     Section 2.10 Temporary Securities.

     Until Definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate  temporary  Securities.  Temporary Securities
shall  be  substantially  in the  form of  Definitive  Securities  but may  have
variations that the Company and the Trustee  consider  appropriate for temporary
Securities.  Without  unreasonable  delay,  the  Company  shall  prepare and the
Trustee, upon receipt of an Officers' Certificate of the Company directing it to
do so,  shall  authenticate  Definitive  Securities  in exchange  for  temporary
Securities.  Until such exchange,  temporary Securities shall be entitled to the
same rights, benefits and privileges as Definitive Securities.

     Section 2.11 Cancellation.

     The  Company  at  any  time  may  deliver  Securities  to the  Trustee  for
cancellation.  The  Registrar  and Paying Agent shall forward to the Trustee any
Securities  surrendered  to them  for  registration  of  transfer,  exchange  or
payment. The Trustee shall cancel all Securities surrendered for registration of
transfer, exchange, payment,  conversion,  replacement or cancellation and shall
destroy  canceled  Securities and  certification of their  destruction  shall be
delivered to the Company  (subject to the record  retention  requirement  of the
Exchange Act) unless by a written order,  signed by two Officers of the Company,
the Company shall direct that canceled Securities be returned to it. The Company
may not issue new Securities to replace Securities that it has redeemed or paid,
converted or that have been delivered to the Trustee for cancellation.

     Section 2.12 Defaulted Interest.

     If the Company  defaults in a payment of  interest  on the  Securities,  it
shall pay the  defaulted  interest  in any  lawful  manner  plus,  to the extent
lawful,  interest  payable on the  defaulted  interest,  to the  persons who are
Holders on a subsequent special record date, which date shall be at the earliest
practicable  date but in all  events at least  five  Business  Days  before  the
payment date, in each case at the rate provided in the Securities and in Section
4.1 hereof. The Company shall, with the consent of the Trustee,  fix or cause to
be fixed each such special record date and payment date. At least 15 days before
the special record date, the Company (or the Trustee,  in the name of and at the
expense of the Company) shall mail

053113\1008\02764\979QGT85.OTH
                                       20



     to Holders a notice  that  states the  special  record  date,  the  related
payment date, and the amount of such interest to be paid.

                                   ARTICLE III
                                   REDEMPTION

     Section 3.1 Notices to Trustee.

     If the  Company  elects  to  redeem  Securities  pursuant  to the  optional
redemption provisions of Section 3.7 hereof, it shall furnish to the Trustee, at
least 60 days but not more than 90 days before a redemption  date,  an Officers'
Certificate  setting forth the Section of this  Indenture  pursuant to which the
redemption  shall occur, the redemption date, the principal amount of Securities
to be redeemed, and the redemption price.

     If the Company is required to make an offer to redeem  Securities  pursuant
to a Change in Control, it shall furnish to the Trustee,  within 60 days after a
Change in Control,  an Officers'  Certificate  setting  forth (a) the Section of
this Indenture pursuant to which the redemption shall occur, (b) the date of the
Change in Control,  (c) the Change in Control  Payment  Date,  (d) the principal
amount of the Securities  offered to be redeemed,  (e) a statement that a Change
in Control has occurred and a description  thereof, and (f) a description of the
procedures  to be  followed  by  Holders  in  order  to  have  their  Securities
repurchased.

     If the Company is required to increase the interest rate on the  Securities
pursuant to the Registration  Rights Agreement,  it shall furnish to the Trustee
not  more  than 15 days  before  the  date  such  interest  is due to be paid an
Officers' Certificate setting forth the rate at which interest on the Securities
is to be paid. The Company, or the Trustee, at the expense of the Company, shall
notify the Holders of the change in interest  rate by notice sent in  accordance
with Section 10.10(e) of this Indenture. Notwithstanding any other provisions of
this  Indenture,  the  Trustee  shall have no duty to inquire as to whether  the
interest  rate on the  Securities  has  increased  and shall not be bound by the
terms  and  conditions  of  the  Registration  Rights  Agreement  or  any  other
agreements or documents between the Holders and the Company.

     Section 3.2 Selection of Securities to be Redeemed.

     If less than all of the  Securities  are to be redeemed,  the Trustee shall
select the  Securities to be redeemed  among the Holders in accordance  with any
method  the  Trustee  considers  fair and  appropriate  (and in such  manner  as
complies with applicable legal and stock exchange requirements,  if any). In the
event of partial  redemption  by lot, the  particular  Securities to be redeemed
shall be selected,  unless otherwise  provided herein, not less than 15 nor more
than 60 days  before the  redemption  date by the Trustee  from the  outstanding
Securities not previously called for redemption.

     The Trustee shall promptly  notify the Company in writing of the Securities
selected for  redemption  and, in the case of any Security  selected for partial
redemption, the

053113\1008\02764\979QGT85.OTH
                                       21



     principal  amount  thereof to be redeemed.  Securities and portions of them
selected shall be in amounts of $1,000 or whole multiples thereof. Provisions of
this  Indenture  that apply to Securities  called for  redemption  also apply to
portions of Securities called for redemption.

     Section 3.3 Notice of Redemption.

     Subject to the  provisions  of Sections  4.10 and 4.11 hereof,  at least 15
days but not more than 60 days before a redemption  date, the Company shall mail
a notice of redemption to each Holder whose Securities are to be redeemed at its
registered address.  The notice shall identify the Securities to be redeemed and
shall state:

     (a) the  redemption  date and that the  right to  convert  such  Securities
pursuant to Article 10 hereof shall be terminated on such date;

     (b) the redemption price;

     (c) if any Security is being redeemed in part, the portion of the principal
amount of such Security to be redeemed and that,  after the redemption date upon
surrender of such  Security,  a new Security of the same series of Securities in
principal amount equal to the unredeemed portion will be issued;

     (d) the name and address of the Paying Agent;

     (e) that Securities called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

     (f) that,  unless the Company  defaults in making such redemption  payment,
interest on Securities  called for redemption  ceases to accrue on and after the
redemption date;

     (g) the paragraph of the Securities and Section of this Indenture  pursuant
to which the Securities called for redemption are being redeemed; and

     (h) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Securities.

     At the Company's  request,  the Trustee shall give the notice of redemption
in the Company's name and at its expense;  provided,  however,  that the Company
shall have  delivered to the Trustee,  at least 60 days prior to the  redemption
date, an Officers' Certificate  requesting that the Trustee give such notice and
setting  forth the  information  to be stated in such  notice as provided in the
preceding paragraph.

     Section 3.4 Effect of Notice of Redemption.

     Once notice of redemption is mailed in accordance  with Section 3.3 hereof,
Securities  called for redemption  become due and payable on the redemption date
at the redemption  price. On and after the redemption  date,  unless the Company
defaults in the payment of the redemption price,  interest shall cease to accrue
on the  Securities or portions of them called for  redemption  and all rights of
Holders of such Securities shall  terminate,  including  without  limitation the
right to convert such Securities, except for the right to receive the redemption
price.  Upon  surrender  to the Paying  Agent,  such  Holders  shall be paid the
redemption  price plus accrued  interest,  if any, to the  redemption  date, but
interest  installments  whose maturity is on or before the redemption date shall
be  payable  to the Holder of record at the close of  business  on the  relevant
record dates referred to in the Securities.

     Section 3.5 Deposit of Redemption Price.

     One Business Day before the redemption date, the Company shall deposit with
the Trustee or with the Paying  Agent  money  sufficient  to pay the  redemption
price of and accrued interest on all Securities to be redeemed on that date. The
Trustee or the Paying Agent shall return to the Company any money deposited with
the  Trustee  or the  Paying  Agent by the  Company  in  excess  of the  amounts
necessary  to pay  the  redemption  price  of,  and  accrued  interest  on,  all
Securities to be redeemed.

     Interest  on the  Securities  to be  redeemed  shall cease to accrue on the
applicable  redemption  date,  whether or not such  Securities are presented for
payment, if the Company provides money sufficient to pay the redemption price of
and accrued  interest  on all  Securities  to be  redeemed on such date.  If any
Security  called  for  redemption  shall  not  be so  paid  upon  surrender  for
redemption  because of the failure of the  Company to comply with the  preceding
paragraph,  interest shall be paid on the unpaid principal,  from the redemption
date until such  principal is paid, and to the extent lawful on any interest not
paid  on such  unpaid  principal,  in each  case  at the  rate  provided  in the
Securities and in Section 4.1 hereof.

     Section 3.6 Securities Redeemed in Part.

     Upon  surrender  of a  Definitive  Security  that is redeemed in part,  the
Company  shall issue and the Trustee  shall  authenticate  for the Holder at the
expense of the  Company a new  Security of the same  series  equal in  principal
amount to the unredeemed portion of the Definitive Security surrendered.

     Section 3.7 Optional Redemption.

     The Company may redeem at any time on or after  September 15,  2000, all or
any portion of the  Securities  outstanding at the following  redemption  prices
expressed as a percentage of the principal amount thereof, if the Securities are

                                    COVENANTS

     Section 4.1 Payment of Securities.

     The Company  shall pay the  principal of and interest on the  Securities on
the dates and in the manner provided in the  Securities.  Principal and interest
shall be considered  paid on the date due if the Paying Agent, if other than the
Company or a Subsidiary  of the Company,  holds at least one Business Day before
that date money  deposited  by the Company in  immediately  available  funds and
designated  for and  sufficient to pay all principal and interest then due. Such
Paying Agent shall return to the Company,  no later than five days following the
date of payment, any money (including accrued interest) that exceeds such amount
of principal and interest paid on the Securities.

     The Company  shall pay interest  (including  post-petition  interest in any
proceeding  under any Bankruptcy Law) on overdue  principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Securities to
the extent  lawful.  The Company  shall pay  interest  (including  post-petition
interest in any proceeding under any Bankruptcy Law) on overdue  installments of
interest (without regard to any applicable grace period) at the same rate to the
extent lawful.

     Section 4.2 Maintenance of Office or Agency.

     The Company shall maintain in the Borough of Manhattan, New York, New York,
an office or  agency  (which  may be an  office  of the  Trustee,  Registrar  or
co-Registrar)  where  Securities may be surrendered for registration of transfer
or exchange  and where  notices and demands to or upon the Company in respect of
the Securities  and this Indenture may be served.  The Company shall give prompt
written  notice to the Trustee of the location,  and any change in the location,
of such office or agency.  If at any time the Company  shall fail to furnish the
Trustee with the address thereof,  such presentations,  surrenders,  notices and
demands may be made or served at the Corporate Trust Office of the Trustee.

                                       24



     The Company also may from time to time  designate one or more other offices
or agencies where the Securities may be presented or surrendered  for any or all
such  purposes and may from time to time rescind  such  designations;  provided,
however,  that no such designation or rescission shall in any manner relieve the
Company of its  obligation  to  maintain  an office or agency in the  Borough of
Manhattan,  New York, New York for such  purposes.  The Company will give prompt
written  notice to the Trustee of any such  designation or rescission and of any
change in the location of any such other office or agency.

     The Company hereby  designates the Corporate Trust Office of the Trustee as
one such office or agency of the Company in accordance with Section 2.3.

     Section 4.3 SEC Reports.

     (a) So long as any of the Securities remain  outstanding and the Company is
subject to the  reporting  requirements  of the Exchange  Act, the Company shall
file with the SEC and  distribute  to the Trustee for delivery to the Holders of
the Securities  copies of the quarterly and annual reports  required to be filed
with the SEC,  and if the  Company  ceases to become  subject  to the  reporting
requirements  of the Exchange Act, the Company  shall  distribute to the Trustee
for delivery to the Holders of the Securities copies of the quarterly and annual
financial  information  that would have been  required  to be filed with the SEC
pursuant to the  Exchange  Act had the  Company  been  subject to the  reporting
requirements  of Section 13 or 15(d) of the  Exchange  Act.  All such  financial
information  shall  include   consolidated   financial   statements   (including
footnotes)  prepared in accordance with GAAP. Such annual financial  information
shall also include an opinion  thereon  expressed by an  independent  accounting
firm  of  established  national  reputation.  All  such  consolidated  financial
statements  shall be accompanied by a  "Management's  Discussion and Analysis of
Financial Condition and Results of Operations."

     (b) The financial  information  to be  distributed to Holders of Securities
shall be filed  with the  Trustee  and  shall be mailed  by the  Trustee  to the
Holders at their addresses appearing in the register of Securities maintained by
the Registrar,  within 15 days after receipt of such financial information.  The
Company shall file such  financial  information  with the Trustee within 15 days
after it is filed with the SEC, if required, but in no event later than 105 days
after the end of the  Company's  fiscal year or later than 60 days after the end
of each of the first three  quarters of each such  fiscal  year,  in the case of
quarterly reports;  provided,  however, that the Trustee's only obligation is to

and not to obtain such information from the Company.

     (c) The Company shall make such financial  information described in Section
4.3 (a) available to prospective purchasers of the Notes.

     (d) The  Company  shall  provide the Trustee  with a  sufficient  number of
copies of all reports and other documents and  information  that the Trustee may

of each fiscal  year,  an  Officers'  Certificate  stating  that a review of the
activities of the Company  during the preceding  fiscal year has been made under
the supervision of the signing  Officers with a view to determining  whether the

Payment Date.  If the Change in Control  Payment Date is on or after an interest

other  securities  laws and  regulations  thereunder to the extent such laws and
regulations are applicable, in the event that a Change in Control occurs and the
Company is required to repurchase the Securities pursuant to this Section 4.10.

     Section 6.2 Acceleration.

     If an Event of Default (other than an Event of Default  specified in clause
(f) or (g) of Section  6.1) occurs and is  continuing,  the Trustee by notice to
the  Company,  or the  Holders of at least 25% in  principal  amount of the then
outstanding Securities by notice to the Company and the Trustee, may declare the
unpaid principal of and any accrued interest on all the Securities to be due and
payable.  Upon such  declaration  the  principal  and interest  shall be due and
payable  immediately.  If an Event of Default  specified in clause (f) or (g) of
Section 6.1 occurs,  such an amount shall ipso facto  become and be  immediately
due and payable  without any declaration or other act on the part of the Trustee
or any  Holder.  The  Holders  of a  majority  in  principal  amount of the then
outstanding  Securities  by  written  notice  to  the  Trustee  may  rescind  an
acceleration  and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default  (except  nonpayment of
principal or interest  that has become due solely  because of the  acceleration)
have been cured or waived.

     Section 6.3 Other Remedies.

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available  remedy to  collect  the  payment  of  principal  or  interest  on the
Securities or to enforce the  performance  of any provision of the Securities or
this Indenture.

     The Trustee may  maintain a  proceeding  even if it does not possess any of
the  Securities  or does not produce any of them in the  proceeding.  A delay or
omission  by the  Trustee  or any  Holder  in  exercising  any  right or  remedy
occurring  upon an Event of  Default  shall  not  impair  the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

     Section 6.4 Waiver of Past Defaults.

     Holders  of  a  majority  in  principal  amount  of  the  then  outstanding
Securities  by notice to the Trustee  may waive an existing  Default or Event of
Default and its consequences, except a continuing Default or Event of Default in
the  payment  of  the   principal  or  interest  on  any  Security   held  by  a
non-consenting  Holder. Upon any such waiver, such Default shall cease to exist,
and any Event of Default  arising  therefrom  shall be deemed to have been cured
for  every  purpose  of this  Indenture.  No such  waiver  shall  extend  to any
subsequent or other Default or impair any right  consequent on any subsequent or
other Default.

     Section 6.5 Control by Majority.

     The Holders of a majority in principal amount of the outstanding Securities
shall have the right to direct  the time,  method  and place of  conducting  any
proceeding  for any remedy  available to the Trustee or exercising  any trust or
power  conferred on such  Trustee;  provided  that (a) such  direction is not in
conflict with any rule of law or with this  Indenture,  (b) the Trustee may take
any other action it deems proper that is not  inconsistent  with such  direction
and (c) such  Holders  have  offered to the  Trustee  indemnity  as  provided in
Section 7.1(e).

     Section 6.6 Limitation on Suits.

     No Holder of any of the  Securities  shall have any right to institute  any
proceeding,  judicial or otherwise,  with respect to this Indenture,  or for the
appointment  of a  receiver  or  trustee  or for any  other  remedy  under  this
Indenture, unless:

     (a) such Holder has previously  given notice to the Trustee of a continuing
Event of Default;

     (b) the Holders of not less than 25% in principal amount of the outstanding
Securities have made written request to the Trustee to institute  proceedings in
respect  of such  Event  of  Default  in its  own  name as  Trustee  under  this
Indenture;

     (c) such Holder or Holders have offered to the Trustee reasonable indemnity
against the costs,  expenses and  liabilities to be incurred in compliance  with
such request;

     (d) the Trustee for 30 days after its receipt of such  notice,  request and
offer of indemnity has failed to institute any such proceeding; and

     (e) no direction  inconsistent  with such written request has been given to
the Trustee  during such 30-day period by the Holders of a majority in principal
amount of the outstanding Securities.

     A Holder  may not use this  Indenture  to  prejudice  the rights of another
Holder or to obtain a preference or priority over another Holder.

     Section 6.7 Rights of Holders to Receive Payment.

     Notwithstanding  any other  provision of this  Indenture,  the right of any
Holder of a  Security  to receive  payment  of  principal  and  interest  on the
Security,  on or after the respective due dates expressed in the Security, or to
bring suit for the  enforcement of any such payment on or after such  respective
dates, shall not be impaired or affected without the consent of the Holder.

     Section 6.8 Collection Suit by Trustee.

     If an Event of Default  specified  in  Section  6.1(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express  trust  against the  Company or any other  obligor for the
whole amount of principal and interest  remaining  unpaid on the  Securities and
interest on overdue  principal  and,  to the extent  lawful,  interest  and such
further  amount  as shall be  sufficient  to cover the  costs  and  expenses  of
collection,  including the reasonable compensation,  expenses, disbursements and
advances of the Trustee, its agents and counsel.

     Section 6.9 Trustee May File Proofs of Claim.

     The Trustee is  authorized to file such proofs of claim and other papers or
documents  as may be  necessary  or advisable in order to have the claims of the
Trustee  (including  any  claim  for  the  reasonable  compensation,   expenses,
disbursements  and  advances of the  Trustee,  its agents and  counsel)  and the
Holders  allowed in any  judicial  proceedings  relative  to the Company (or any
other obligor upon the  Securities),  its creditors or its property and shall be
entitled and  empowered to collect,  receive and  distribute  any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee,  and if the Trustee  shall  consent to the making of such  payments
directly  to the  Holders,  to pay to the  Trustee  any amount due to it for the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel,  and any other amounts due the Trustee under Section 7.7
hereof.  To the  extent  that the  payment of any such  compensation,  expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee  under  Section 7.7 hereof out of the estate in any such
proceeding, shall be denied for any reason, payment of the same shall be secured
by a Lien on,  and shall be paid out of, any and all  distributions,  dividends,
money, securities and other properties that the Holders of the Securities may be
entitled to receive in such proceeding  whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any  Holder any plan of  reorganization,  arrangement,  adjustment  or
composition  affecting the Securities or the rights of any Holder thereof, or to
authorize  the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

     Section 6.10 Priorities.

     If the Trustee collects any money pursuant to this Article 6,  it shall pay
out the money in the following order:

     First:  to the  Trustee,  its agents and  attorneys  for  amounts due under
Section 7.7,  including  payment of all  compensation,  expense and  liabilities
incurred,  and all advances  made,  by the Trustee and the costs and expenses of
collection.

     Second:  to  Holders  for  amounts  due and  unpaid on the  Securities  for
principal and  interest,  ratably,  without  preference or priority of any kind,
according to the amounts due and payable on the  Securities  for  principal  and

     Third: to the Company or to such party as a court of competent jurisdiction
shall direct.

     The  Trustee  may fix a record  date and  payment  date for any  payment to
Holders.

     Section 6.11 Undertaking for Costs.

or in any suit  against the  Trustee for any action  taken or omitted by it as a
Trustee,  a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs,  including  reasonable  attorney' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses  made by the party  litigant.  This Section does

     (a) If an Event of Default  has  occurred  and is  continuing,  the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same  degree of care and skill in their  exercise,  as a prudent  person
would exercise or use under the circumstances in the conduct of his own affairs.

     (b) Except during the continuance of an Event of Default:

     (i) the duties of the  Trustee  shall be  determined  solely by the express
provisions of this Indenture,  and the Trustee  undertakes to perform only those
duties that are specifically  set forth in this Indenture and no others,  and no
implied  covenants or obligations  shall be read into this Indenture against the
Trustee.

     (ii) In the absence of bad faith on its part, the Trustee may  conclusively
rely,  as to the truth of the  statements  and the  correctness  of the opinions
expressed  therein,  upon certificates or opinions  furnished to the Trustee and
conforming to the requirements of this Indenture;  provided,  however,  that the
Trustee shall examine the certificates and opinions to determine  whether or not
they conform to the requirements of this Indenture.

                                       35




     (c) The Trustee may not be relieved from  liabilities for its own negligent
action, its own negligent failure to act, or its own willful misconduct,  except
that:

     (i) this  paragraph  does not limit the  effect  of  paragraph  (b) of this
Section 7.1;

     (ii) the Trustee shall not be liable for any error of judgment made in good
faith by a  Responsible  Officer,  unless  it is  proved  that the  Trustee  was
negligent in ascertaining the pertinent facts; and

     (iii) the Trustee  shall not be liable with  respect to any action it takes
or omits to take in good faith in  accordance  with a  direction  received by it
pursuant to Section 6.5.

     (d) Whether or not therein  expressly so provided,  every provision of this
Indenture that in any way relates to the Trustee is subject to the provisions of
this Section 7.1.

     (e) No provision of this  Indenture  shall require the Trustee to expend or
risk its own funds or incur any liability. The Trustee may refuse to perform any
duty or exercise any right or power unless it receives indemnity satisfactory to
it against any loss, liability or expense.

     (f) The Trustee  shall not be liable for interest on any money  received by
it except as the Trustee may agree in writing  with the  Company.  Money held in
trust by the  Trustee  need not be  segregated  from other  funds  except to the
extent required by law.

     (g) The Trustee shall have no  responsibility  for making any  calculations
hereunder,  including,  without limitation,  the amount of interest owing on the
Securities under any of the provisions of the Registration Rights Agreement. The
Company shall  deliver to the Trustee an Officers'  Certificate  specifying  any
additional interest due under the Registration Rights Agreement on or before the
15th day prior to an interest payment date.

     Section 7.2 Rights of Trustee.

     (a) The Trustee may rely and shall be fully  protected  in relying upon any
document  believed by it to be genuine and to have been signed or  presented  by
the proper Person. The Trustee need not investigate any fact or matter stated in
the document.

     (b) Before the Trustee  acts or  refrains  from  acting,  it may require an
Officers'  Certificate or an Opinion of Counsel,  or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in  reliance on
such Officers'  Certificate or Opinion of Counsel.  The Trustee may consult with
counsel and the written  advice of such counsel or any Opinion of Counsel  shall
be full and complete  authorization  and protection from liability in respect of
any action  taken,  suffered  or omitted  by it  hereunder  in good faith and in
reliance thereon.

                                       36




     (c) The Trustee may act through agents and shall not be responsible for the
misconduct or negligence of any agent appointed and monitored with due care.

     (d) The  Trustee  shall not be liable  for any  action it takes or omits to
take in good faith which it believes  to be  authorized  or within its rights or
powers conferred upon it by this Indenture.

     (e) Unless otherwise  specifically provided in this Indenture,  any demand,
request,  direction or notice from the Company  shall be sufficient if signed by
an Officer of the Company.

     Section 7.3 Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities  and may otherwise  deal with the Company or any Affiliate
of the Company  with the same rights it would have if it were not  Trustee.  Any
Agent  may do the same with like  rights;  provided,  however,  the  Trustee  is
subject to Sections 7.10 and 7.11.

     Section 7.4 Trustee's Disclaimer.

     The Trustee makes no  representation as to the validity or adequacy of this
Indenture, the Securities or any documents relating to the Securities.  It shall
not be accountable  for the Company's use of the proceeds from the Securities or
any  money  paid to the  Company  or upon the  Company's  discretion  under  any
provision  hereof. It shall not be responsible for the use or application of any
money  received  by any Paying  Agent other than the Trustee and it shall not be
responsible  for  any  statement  or  recital  herein  or any  statement  in the
Securities or any other  document in connection  with the sale of the Securities
or pursuant to this Indenture, other than its certificate of authentication.

     Section 7.5 Notice of Defaults.

     If a Default or Event of  Default  occurs  and is  continuing  and if it is
known to the Trustee,  the Trustee shall mail to Holders a notice of the Default
or Event of Default  within 90 days  after it  occurs.  A Default or an Event of
Default shall not be considered  known to the Trustee  unless it is a Default or
Event of Default under Section  6.1(a) or (b) or the Trustee shall have received
notice thereof, in accordance with this Indenture,  from the Company or from the
Holders of a majority in principal amount of the outstanding Securities,  and in
the  absence of such  notice the Trustee  may  conclusively  assume  there is no
Default or Event of Default. Except in the case of a Default or Event of Default
in payment of principal or interest on any  Security  (including  the failure to
make a mandatory  redemption  pursuant  hereto),  the Trustee may  withhold  the
notice if and so long as a committee of its  Responsible  Officers in good faith
determines that withholding the notice is in the interests of Holders.

     Section 7.6 Reports by Trustee to Holders.

     Within 60 days after each  August 1  beginning  with the August 1 following
the date  hereof,  the Trustee  shall mail to Holders a brief report dated as of
such reporting  date that complies with TIA S 313(a) (but if no event  described
in TIA S 313(a) has occurred within the 12 months  preceding the reporting date,
no report need be transmitted). The Trustee also shall comply with TIA S 313(n).
The Trustee shall also transmit by mail all reports as required by TIA S 313(c).

     At the  time of its  mailing  to  Holders,  a copy of each  report  sent to
Holders  shall  be  filed  with the SEC and each  stock  exchange  on which  the
Securities are listed.  The Company shall  promptly  notify the Trustee when the
Securities are listed on any stock exchange.

     Section 7.7 Compensation and Indemnity.

     The  Company  shall  pay  to the  Trustee  from  time  to  time  reasonable
compensation  for its acceptance of this Indenture and services  hereunder.  The
Trustee's  compensation  shall not be  limited by any law on  compensation  of a
trustee of an express  trust.  The Company  shall  reimburse  the  Trustee  upon
request for all reasonable disbursements, advances and expenses incurred or made
by it. Such expenses  shall include the reasonable  compensation,  disbursements
and expenses of the Trustee's agents and counsel.

     The  Company  shall  indemnify  the  Trustee  against  any and all  losses,
liabilities or expenses  incurred by it arising out of or in connection with the
acceptance or administration  of its duties under this Indenture,  except as set
forth in the next  paragraph.  The Trustee shall notify the Company  promptly of
any claim for which it may seek  indemnity.  The Company shall defend the claim,
and the Trustee  shall  cooperate in the defense.  The Trustee may have separate
counsel,  and the Company  shall pay the  reasonable  fees and  expenses of such
counsel.  The Company need not pay for any settlement  made without its consent,
which consent shall not be unreasonably withheld.

     The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through its own negligence or bad faith.

     To secure the Company's  payment  obligations in this Section,  the Trustee
shall have a Lien with  priority  over the  Securities  on all money or property
held or collected by the Trustee, except that held in trust to pay principal and
interest on particular Securities.  Such Lien shall survive the satisfaction and
discharge of this Indenture.

     When the  Trustee  incurs  expenses or renders  services  after an Event of
Default  specified  in  Section  6.1(f)  or (g)  occurs,  the  expenses  and the
compensation   for  the  services  are  intended  to   constitute   expenses  of
administration under any Bankruptcy Law.

     Section 7.8 Replacement of Trustee.

     A  resignation  or removal of the  Trustee and  appointment  of a successor
Trustee shall become effective only upon the successor  Truste's  acceptance of
appointment as provided in this Section 7.8.

     The Trustee may resign at any time and be discharged  from the trust hereby
created by so  notifying  the  Company.  The Holders of a majority in  principal
amount of the then outstanding Securities may remove the Trustee by so notifying
the Trustee and the Company. The Company may remove the Trustee if:

     (a) the Trustee fails to comply with Section 7.10;

     (b) the  Trustee is  adjudged a bankrupt  or an  insolvent  or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

     (c) a  Custodian  or public  officer  takes  charge of the  Trustee  or its
property; or

     (d) the Trustee becomes incapable of acting.

     If the Trustee  resigns or is removed or if a vacancy  exists in the office
of Trustee  for any  reason,  the  Company  shall  promptly  appoint a successor
Trustee.  Within one year after the successor Trustee takes office,  the Holders
of a majority in principal amount of the then outstanding Securities may appoint
a successor Trustee to replace the successor Trustee appointed by the Company.

     If a  successor  Trustee  does not take  office  within  60 days  after the
retiring Trustee resigns or is removed,  the retiring Trustee,  the Company,  or
the  Holders  of at  least  10% in  principal  amount  of the  then  outstanding
Securities may petition any court of competent  jurisdiction for the appointment
of a successor Trustee.

     If the Trustee  after  written  request by any Holder who had been a Holder
for at least six months  fails to comply  with  Section  7.10,  such  Holder may
petition any court of competent  jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

     A successor  Trustee shall deliver a written  acceptance of its appointment
to the retiring Trustee and to the Company. Thereupon the resignation or removal
of the retiring Trustee shall become effective,  and the successor Trustee shall
have all of the rights,  powers and duties of the Trustee under this  Indenture.
The successor Trustee shall mail a notice of its succession to the Holders.  The
retiring  Trustee shall promptly  transfer all property held by it as Trustee to
the successor  Trustee,  provided all sums owing to the Trustee  hereunder  have
been paid and subject to the Lien  provided for in Section 7.7.  Notwithstanding
replacement  of  the  Trustee  pursuant  to  this  Section  7.8,  the  Company's
obligations  under  Section  7.7 hereof  shall  continue  for the benefit of the
retiring Trustee.

     Section 7.9 Successor Trustee by Merger, etc.

     If the Trustee  consolidates,  merges or converts into, or transfers all or
substantially all of its corporate trust business to, another  corporation,  the
successor corporation without any further act shall be the successor Trustee.

     Section 7.10 Eligibility; Disqualification.

     There shall at all times be a Trustee hereunder that shall be a corporation
organized and doing  business  under the laws of the United States of America or
of any state thereof  authorized under such laws to exercise  corporate  trustee
power,  shall be  subject  to  supervision  or  examination  by federal or state
authority and shall have a combined  capital and surplus of at least $10 million
as set forth in its most recent published annual report of condition.

     This Indenture  shall always have a Trustee who satisfies the  requirements
of TIA S  310(a)(1).  The  Trustee  is subject  to TIA S 310(b),  including  the
optional provision permitted by the second sentence of TIA S 310(b)(9).

     Section 7.11 Preferential Collection of Claims Against Company.

     The Trustee is subject to TIA S 311(a), excluding any creditor relationship
listed in TIA S 311(b).  A Trustee who has resigned or has been removed shall be
subject to TIA S 311(a) to the extent indicated therein.

     Section 7.12 No Obligation of the Trustee.

     (a)  The  Trustee  shall  have  no  responsibility  or  obligation  to  any
beneficial  owner of a Global  Security or a  participant  in the  Depository or
other Person with respect to the  accuracy of the records of the  Depository  or
its nominee or of any participant, with respect to any ownership interest in the
Securities  or  with  respect  to  the  delivery  to  any  participant,  member,
beneficial  owner or other  Person  (other  than the  Depository)  of any notice
(including any notice of redemption) or the payment of any amount, under or with
respect to such Securities.  All notices and  communications  to be given to the
Holder and all  payments  to be made to Holders  under the  Securities  shall be
given or made only to or upon the order of the  registered  Holders (which shall
be the Depository or its nominee in the case of a Global  Security).  The rights
of beneficial  owners in any Global  Security may only be exercised  through the
Depository subject to the Applicable Procedures.  The Trustee may rely and shall
be fully protected in relying upon information  furnished by the Depository with
respect to its members, participants and any beneficial owners.

     (b) The Trustee shall have no  obligation or duty to monitor,  determine or
inquire as to compliance  with any  restrictions  on transfer  imposed under the
Indenture or under  applicable  law with respect to any transfer of any interest
in  any  security   (including  any  transfers   between  or  among   Depository
participants, members or beneficial owners in any Global Security) other than to
require delivery of such certificates and other documentation or

     evidence as are expressly  required by, and to do so if and when  expressly
required  by, the terms of the  Indenture,  and to examine the same to determine
substantial compliance as to form with the express requirements hereof.


                                  ARTICLE VIII
                             DISCHARGE OF INDENTURE

     Section 8.1 Termination of Company's Obligation.

     This  Indenture  shall  cease  to be of  further  effect  (except  that the
Company's  obligations  under Section 7.7 and 8.4, and the Company's,  Trustee's
and  Paying  Agent's  obligations  under  Section  8.3 shall  survive)  when all
outstanding Securities theretofore  authenticated and issued have been delivered
(other than  destroyed,  lost or stolen  Securities  that have been  replaced or
paid) to the Trustee for  cancellation and the Company has paid all sums payable
by the Company  under this  Indenture.  In addition,  subject to the  conditions
described below, at the Company's option,  either (a) the Company will be deemed
to have been discharged from their obligations with respect to the Securities on
the 31st day after the applicable conditions set forth below have been satisfied
or (b) the Company shall cease to be under any obligation to comply with Article
4 of this Indenture,  at any time after the conditions set forth below have been
satisfied:

     (i) the Company has  deposited or caused to be deposited  irrevocably  with
the Trustee as trust funds in trust,  specifically  pledged as security for, and
dedicated  solely to, the benefit of the  Holders  (A) money or (B)  noncallable
U.S. Government Obligations, which through the payment of interest and principal
in respect  thereof in  accordance  with their terms,  will  provide  either (i)
payment  in full  of  principal,  premium  on,  if any,  and  interest  on,  the
outstanding  Securities  as of the date of such  payment,  or (II)  (without any
reinvestment  of such interest or principal),  not later than one day before the
due date of any payment, money or (C) a combination of (A) and (B), in an amount
sufficient,  in the  opinion  (with  respect  to (B) and  (C))  of a  nationally
recognized  firm  of  independent  public  accountants  expressed  in a  written
certification  thereof  delivered  to the  Trustee at or before the time of such
deposit,  to pay and discharge each  installment of principal of, premium on, if
any, and interest on, the outstanding  Securities on the dates such installments
are due;

     (ii) no Default or Event of Default has occurred and is  continuing  on the
date of such  deposit  or  shall  occur as a result  of such  deposit,  and such
deposit  shall not result in a breach or violation  of, or  constitute a Default
under,  any other  instrument to which the Company is a party to or is bound, as
evidenced  to the Trustee in an Officers'  Certificate  delivered to the Trustee
concurrently with such deposit;

     (iii) the Company has paid or duly provided for payment of all amounts then
due or to become due to the Trustee  pursuant  to Section 7.7 of the  Indenture;
and

                                       41



     (iv) the Company has  delivered  to the Trustee an  Officers'  Certificate,
stating that there has been  compliance with all conditions  precedent  provided
for in the  Indenture  relating  to  the  satisfaction  and  discharge  of  this
Indenture.

     If the Company  selects option (a) above,  this Indenture shall cease to be
of further effect on the 31st day after the conditions set forth above have been
satisfied (except as provided in this paragraph),  and the Trustee, on demand of
the Company, shall execute proper instruments acknowledging  confirmation of and
discharge  under this  Indenture  and the  Securities;  provided,  however,  the
Company's  obligations  in Sections  2.3, 2.4, 2.5, 2.6, 4.1, 4.6, 7.7, 7.8, 8.3
and 8.4, and the Trustee's and Paying  Agent's  obligations in Section 8.3 shall
survive until the Securities  are no longer  outstanding.  Thereafter,  only the
Company's  obligations under Sections 7.7 and 8.4 and the Company's,  Trustee's,
and Paying Agent's  obligations under Section 8.3 shall survive.  If the Company
elects  option (b) above,  the Company's  obligations  under Article 4 hereunder
shall  terminate  upon  the  satisfaction  of  the  conditions,  and  all  other
obligations  shall  survive  until the  Securities  are no  longer  outstanding.
Thereafter,  only the Company's  obligations  under Sections 7.7 and 8.4 and the
Company's,  Trustee's  and Paying  Agent's  obligations  under Section 8.3 above
shall survive.

     After such  irrevocable  deposit is made  pursuant to this  Section 8.1 and
satisfaction  of the  other  conditions  set forth  herein,  the  Trustee,  upon
request, shall acknowledge in writing the discharge of the Company's obligations
under this Indenture except for those surviving obligations specified above.

     In order to have money  available on a payment date to pay  principal of or
interest on the Securities,  the U.S. Government Obligations shall be payable as
to  principal  or interest at least one Business Day before such payment date in
such amounts as will provide the necessary money.  U.S.  Government  Obligations
shall not be callable at the issuer's option.

     Section 8.2 Application of Trust Money.

     The Trustee or a trustee  satisfactory to the Trustee and the Company shall
hold in trust money or U.S. Government Obligations deposited with it pursuant to
Section  8.1.  It shall  apply  the  deposited  money  and the  money  from U.S.
Government  Obligations  through the Paying  Agent and in  accordance  with this
Indenture to the payment of principal and interest on the Securities.

     Section 8.3 Repayment to Company.

     To the extent permitted by applicable law, the Trustee and the Paying Agent
shall  promptly  pay to the Company  upon  written  request any excess  money or
securities  held by them  at any  time in  excess  of  amounts  required  to pay
principal of or interest on the Securities.

     The Trustee and the Paying  Agent  shall pay to the  Company  upon  written
request any money held by them for the  payment of  principal  or interest  that
remains

053113\1008\02764\979QGT85.OTH
                                       42



     unclaimed  for one year after the date upon which such  payment  shall have
become due; provided,  however, that the Company shall have either caused notice
of such  payment to be mailed to each  Holder  entitled  thereto no less than 30
days before such  repayment  or within such  period  shall have  published  such
notice in a financial newspaper of widespread circulation published in New York,
New York. After payment to the Company,  Holders entitled to the money must look
to the Company for payment as general  creditors unless an applicable  abandoned
property law  designates  another  person,  and all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

     Section 8.4 Reinstatement.

     If the  Trustee  or  Paying  Agent is  unable  to apply  any  money or U.S.
Government  Obligations  in  accordance  with Section 8.2 by reason of any legal
proceeding  or by reason of any order or judgment  of any court or  governmental
authority enjoining,  restraining or otherwise prohibiting such application, the
Company's  obligations  under this Indenture and the Securities shall be revived
and  reinstated as though no deposit had occurred  pursuant to Section 8.1 until
such time as the Trustee or Paying Agent is permitted to apply all such money or
U.S. Government  Obligations in accordance with Section 8.2; provided,  however,
that if the Company has made any  payment of  interest  on or  principal  of any
Securities because of the reinstatement of its obligations, the Company shall be
subrogated  to the rights of the  Holders  of such  Securities  to receive  such
payment  from the money or U.S.  Government  Obligations  held by the Trustee or
Paying Agent.


                                   ARTICLE IX
                                   AMENDMENTS

     Section 9.1 Without Consent of Holders.

     The Company and the Trustee  may amend this  Indenture  and the  Securities
without the consent of any Holder:

     (a) to cure any ambiguity, defect or inconsistency;

     (b) to comply with Section 5.1;

     (c) to provide for  uncertificated  Securities in addition to  certificated
Securities;

     (d) to make any change  that does not  adversely  affect  the legal  rights
hereunder of any Holder; and

     (e) to comply with  requirements  of the SEC in order to effect or maintain
the qualification of this Indenture under the TIA.

     Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such Supplemental  Indenture and upon
receipt by

053113\1008\02764\979QGT85.OTH
                                       43



     the Trustee of the documents  described in Section 9.6 hereof,  the Trustee
shall  join with the  Company in the  execution  of any  Supplemental  Indenture
authorized  or permitted by the terms of this  Indenture and to make any further
appropriate agreements and stipulations which may be therein contained,  but the
Trustee shall not be obligated to enter into such  Supplemental  Indenture which
affects its own rights, duties or immunities under this Indenture or otherwise.

     Section 9.2 With Consent of Holders.

     Except as provided  below in this  Section 9.2, the Company and the Trustee
may amend this  Indenture  or the  Securities  with the  written  consent of the
Holders  of at least a  majority  in  principal  amount of the then  outstanding
Securities. The Holders of a majority in principal amount of the Securities then
outstanding  may, or the Trustee  with the written  consent of the Holders of at
least a majority in principal  amount of the then  outstanding  Securities  may,
waive  compliance in a particular  instance by the Company with any provision of
this Indenture or the Securities.

     Upon the request of the Company,  accompanied  by a resolution of its Board
of Directors authorizing the execution of any such Supplemental  Indenture,  and
upon the filing with the Trustee of evidence  satisfactory to the Trustee of the
consent of the  Holders as  aforesaid,  and upon  receipt by the  Trustee of the
documents  described  in Section  9.6 hereof,  the  Trustee  shall join with the
Company in the execution of such Supplemental Indenture unless such Supplemental
Indenture  affects the  Trustee's own rights,  duties or  immunities  under this
Indenture or  otherwise,  in which case the Trustee may in its  discretion,  but
shall not be obligated to, enter into such Supplemental Indenture.

     It shall not be necessary for the consent of the Holders under this Section
to approve the particular form of any proposed amendment or waiver, but it shall
be sufficient if such consent approves the substance thereof.

     After an  amendment or waiver under this  Section  becomes  effective,  the
Company  shall mail to the Holders of each  Security  affected  thereby a notice
briefly  describing the amendment or waiver.  Any failure of the Company to mail
such notice,  or any defect therein,  shall not,  however,  in any way impair or
affect the validity of any such  Supplemental  Indenture  or waiver.  Subject to
Sections 6.4 and 6.7 hereof,  the Holders of a majority in  principal  amount of
the Securities then outstanding may waive compliance in a particular instance by
the Company with any provision of this  Indenture or the  Securities,  provided,
however,  that  without the consent of each Holder  affected,  an  amendment  or
waiver  under this  Section may not (with  respect to any  Securities  held by a
non-consenting Holder):

     (a) reduce the principal amount of Securities whose Holders must consent to
an amendment or waiver;

     (b)  reduce  the  rate of or  change  the  time for  payment  of  interest,
including default interest, on any Security;


053113\1008\02764\979QGT85.OTH

     (c) reduce the principal of or change the fixed maturity of any Security or
alter the optional or mandatory redemption  provisions or the price at which the
Company  shall offer to purchase  such  Securities  pursuant to Sections 3.7 and
4.10 hereof;

     (d) make any  Security  payable  in money  other  than  that  stated in the
Security;


     (e) make any change in Section  6.4 or 6.7  hereof or in this  sentence  of
this Section 9.2; or

     (f) waive a Default in the payment of principal of, premium or interest on,
or redemption payment with respect to, any Security.

     Section 9.3 Compliance with Trust Indenture Act.

     Every amendment to this Indenture or the Securities shall be set forth in a
Supplemental Indenture that complies with the TIA as then in effect.

     Section 9.4 Revocation and Effect of Consents.

     Until an amendment or waiver becomes effective, a consent to it by a Holder
of a Security is a continuing  consent by the Holder and every subsequent Holder
of a  Security  or portion of a  Security  that  evidences  the same debt as the
consenting Holder's Security, even if notation of the consent is not made on any
Security;  provided,  however,  that any such  Holder or  subsequent  Holder may
revoke the consent as to his or her  security if the  Trustee  receives  written
notice of revocation before the date the waiver or amendment becomes  effective.
An  amendment  or waiver  becomes  effective  in  accordance  with its terms and
thereafter binds every Holder.

     The  Company  may fix a record  date for  determining  which  Holders  must
consent to such  amendment or waiver.  If the Company  fixes a record date,  the
record  date  shall be  fixed  at (a) the  later  of 30 days  before  the  first
solicitation  of such  consent  or the date of the most  recent  list of Holders
furnished to the Trustee before such  solicitation  pursuant to Section 2.05, or
(b) such other date as the Company shall designate.

     Section 9.5 Notation on or Exchange of Securities.

     The Trustee may place an appropriate  notation about an amendment or waiver
on any  Security  thereafter  authenticated.  The  Company in  exchange  for all
Securities  may issue and the Trustee shall  authenticate  new Securities of the
same series that reflect the amendment or waiver.

     Failure to make the  appropriate  notation  or issue a new  Security of the
same  series  shall not affect the  validity  and  effect of such  amendment  or
waiver.

     Section 9.6 Trustee to Sign Amendments, etc.

     The Trustee shall sign any amendment or Supplemental  Indenture  authorized
pursuant  to this  Article 9 if the  amendment  does not  adversely  affect  the
rights,  duties,  liabilities  or  immunities  of the Trustee.  If it does,  the
Trustee  may,  but need  not,  sign it.  In  signing  or  refusing  to sign such
amendment or Supplemental  Indenture,  the Trustee shall be entitled to receive,
and,  subject to Section  7.1,  shall be fully  protected  in relying  upon,  an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that such
amendment  or  Supplemental   Indenture  is  authorized  or  permitted  by  this
Indenture,  that it is not inconsistent  herewith, and that it will be valid and
binding upon the Company in accordance with its terms.  The Company may not sign
an amendment or Supplemental Indenture until the Board of Directors approves it.

                                   CONVERSION

     Section 10.1 Right to Convert.

     (a) Subject to and upon  compliance  with the provisions of this Indenture,
at any time on or after 270 days after the Issue Date and on or before maturity,
each Holder shall have the right, at its option, to convert the principal amount
of any Security,  or any portion of such  principal  amount which is $1,000 or a
whole multiple thereof,  into, at the Company's option, either (i) cash, payable
by the  Company to the Paying  Agent for the benefit of such Holder in an amount
equal to the Current  Market  Price,  as of the  conversion  date, of the Common
Stock to which the Securities would otherwise be converted,  or (ii) that number
of fully paid and  nonassessable  shares of Common  Stock (as such shares  shall
then be constituted)  obtained by dividing the principal  amount of the Security
or portion thereof  surrendered for conversion by the conversion price in effect
at such time,  or (iii) a  combination  of cash and Common Stock in  proportions
determined by the Company in its sole discretion;  provided,  however,  that the
Company's  option to convert  Securities into cash under  Section 10.1(a)(i)  or
into a combination  of cash and Common Stock under  Section 10.1(a)(iii),  shall
terminate at the close of business on the date the Company's  charter is amended
to increase  the number of shares of  authorized  Common  Stock to at least that
number of shares sufficient to reserve for the conversion of all the Notes.

     (b)  Notwithstanding  anything in this  Section 10.1 to the  contrary,  the
right to convert  with  respect to any  Security  or portion of a Security  that
shall be called for redemption or delivered for  repurchase,  shall terminate at
the close of  business  on the date fixed for  redemption  of such  Security  or
portion of a Security on the second  trading  day  preceding a Change in Control
Payment  Date,  as the case may be,  unless the Company shall default in payment
due upon redemption or repurchase thereof.

     (c) A holder of  Securities  is not  entitled  to any rights of a holder of
Common Stock until such holder has converted his Securities to Common Stock, and
only to the extent such  Securities  are deemed to have been converted to Common
Stock under this Article 10.

     Section 10.2 Exercise of Conversion Privilege;  Issuance of Common Stock on
Conversion; No Adjustment for Interest or Dividends.

     In order to exercise the conversion  privilege,  the Holder of any Security
to be  converted  in  whole  or in part  shall  surrender  such  Security,  duly
endorsed,  at an office or agency  maintained by the Company pursuant to Section
2.3,  accompanied by the funds,  if any,  required by the last paragraph of this
Section 10.2,  and shall give written  notice of conversion in the form provided
on the  Securities  (or such other notice that is  acceptable to the Company) to
the  Company at such  office or agency  that the Holder  elects to convert  such
Security or the portion  thereof  specified in such notice,  stating the name or
names (with  address) in which the  certificate  or  certificates  for shares of
Common Stock, if any, that shall be issuable on such conversion shall be issued.
So long as the Company's option to convert Securities into cash or a combination
of cash and Common Stock exists, then within five business days after receipt of
such Holder's notice of conversion,  the Company shall notify such Holder of the
Company's  election to convert the  Securities to cash or,  Common  Stock,  or a
combination  of cash and Common Stock.  Holder shall then deliver to the Company
any transfer taxes required pursuant to Section 10.7.  Each Security surrendered
for conversion shall,  unless the shares issuable on conversion are to be issued
in the same name as the registration  under such Security,  be duly endorsed by,
or be accompanied by instruments of transfer in form satisfactory to the Company
duly  executed by, the Holder or his duly  authorized  attorney.  Holder may not
withdraw its  conversion  notice after  receipt of the  Company's  notice of its
election regarding conversion.

     As promptly as  practicable  after the  surrender of such  Security and the
receipt of such notice and funds, if any, as aforesaid, (a) if the conversion is
for Common  Stock,  the Company  shall issue and shall deliver at such office or
agency  to  such  Holder,  or  on  his  written  order,  (i)  a  certificate  or
certificates  for the number of full shares issuable upon the conversion of such
Security or portion  thereof in accordance  with the provisions of this Article,
and (ii) a check or cash in respect of any  fractional  interest in respect of a
share of Common Stock arising upon such  conversion as provided in Section 10.3,
or (b) if the  conversion is for cash or a combination of cash and Common Stock,
the Company shall,  one business day after its notice to Holder of the Company's
election regarding conversion, deposit with Paying Agent money sufficient to pay
the  conversion  price for, and all accrued  interest on, the  Securities  being
converted to cash.  In case any Security of a  denomination  greater than $1,000
shall be  surrendered  for partial  conversion,  and subject to  Article 2,  the
Company shall execute and the Trustee shall  authenticate and deliver to or upon
the written order of the holder of the Note so  surrendered,  without  charge to
him, a new Security or Securities in  authorized  denominations  in an aggregate
principal amount equal to the unconverted portion of the surrendered Security.

     Each conversion  shall be deemed to have been effected on the date on which
such Security shall have been  surrendered  (accompanied  by the funds,  if any,
required by the last paragraph of this  Section 10.2) and such notice shall have
been received by the Company, as aforesaid, and, if the conversion is for Common
Stock,  the person in whose name any certificate or  certificates  for shares of
Common  Stock shall be  issuable  upon such  conversion  shall be deemed to have
become on said date the  holder of  record of the  shares  represented  thereby;
provided,  however,  that any such surrender on any date when the stock transfer
books of the Company shall be closed shall  constitute  the person in whose name
the certificates are to be

053113\1008\02764\979QGT85.OTH
                                       47



     issued as the record  holder  thereof  for all  purposes on the next day on
which such stock transfer books are open,  but such  conversion  shall be at the
conversion  price in effect on the date upon which such Security shall have been
surrendered.

     Any  Security or portion  thereof  surrendered  for  conversion  during the
period from the close of business  on the record date for any  interest  payment
date to the opening of business on such interest payment date shall (unless such
Security  or  portion  thereof  being  converted  shall  have  been  called  for
redemption  on a date in such  period)  be  accompanied  by  payment,  in  funds
acceptable to the Company,  of an amount equal to the interest otherwise payable
on such interest payment date on the principal amount being converted; provided,
however,  that no such  payment need be made if there shall exist at the time of
conversion  a default in the payment of interest  on the  Securities.  An amount
equal to such payment shall be paid by the Company on such interest payment date
to the holder of such  Security at the close of  business  on such record  date;
provided,  however, that if the Company shall default in the payment of interest
on such interest  payment date, such amount shall be paid to the person who made
such  required  payment.  Except  as  provided  above in this  Section 10.2,  no
adjustment shall be made for interest  accrued on any Security  converted or for
dividends on any shares issued upon the  conversion of such Security as provided
in this Article 10. If any Security or portion thereof which has been called for
redemption  on a date during the period from the close of business on the record
date for any interest  payment date to the opening of business on such  interest
payment date is surrendered for conversion during such period, no interest shall
be payable to the holder of such Security on account of such Security or portion
thereof.

     Section 10.3 Cash Payments in Lieu of Fractional Shares.

     No  fractional  shares of  Common  Stock or scrip  representing  fractional
shares shall be issued upon conversion of Securities.  If more than one Security
shall be surrendered  for conversion at one time by the same holder,  the number
of full shares which shall be issuable upon conversion  shall be computed on the
basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered.  If any fractional share
of Common  Stock  would be  issuable  upon the  conversion  of any  Security  or
Securities, the Company shall make an adjustment therefor in cash at the current
market value thereof.  The current market value of a share of Common Stock shall
be the  Closing  Price on the day (that is not a Legal  Holiday  as  defined  in
Section  12.8) before the day on which the  Securities  (or  specified  portions
thereof)  are deemed to have been  converted  and such  Closing  Price  shall be
determined as provided in subsection (f) of Section 10.5.

     Section 10.4 Conversion Price.

     The  conversion  price  shall  be as  specified  in the  form  of  Security
hereinabove set forth, subject to adjustment as provided in this Article.


053113\1008\02764\979QGT85.OTH

     Section 10.5 Adjustment of Conversion Price.

     (a) In case the Company shall (i) pay a dividend,  or make a  distribution,
in  shares  of its  Common  Stock  on  its  Common  Stock,  (ii)  subdivide  its
outstanding  Common Stock into a greater number of shares,  or (iii) combine its
outstanding  Common Stock into a smaller number of shares,  the conversion price
in effect  immediately prior thereto shall be adjusted so that the holder of any
Security thereafter  surrendered for conversion shall be entitled to receive the
number of shares of Common Stock of the Company that he would have owned or have
been  entitled to receive  after the  happening  of any of the events  described
above had such Security been converted  immediately before the happening of such
event. An adjustment made pursuant to this subsection (a) shall become effective
immediately  after the record  date in the case of a dividend  and shall  become
effective  immediately  after the effective  date in the case of  subdivision or
combination.

     (b) In case the Company  shall  issue  rights or warrants to all holders of
its Common Stock  entitling them (for a period expiring within 45 days after the
record date  mentioned  below) to  subscribe  for or purchase  Common Stock at a
price per share less than the Current  Market Price per share of Common Stock at
the record date for the  determination of stockholders  entitled to receive such
rights or warrants,  except as provided in subsection (f) below,  the conversion
price in effect  immediately  prior  thereto  shall be adjusted so that the same
shall equal the price  determined by multiplying the conversion  price in effect
immediately before the date of issuance of such rights or warrants by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
on the date of issuance  of such  rights or  warrants  plus the number of shares
which the  aggregate  offering  price of the total  number of shares so  offered
would purchase at such Current Market Price (determined by multiplying the total
number of shares by the  exercise  price of such rights or warrants and dividing
the  product  so  obtained  by the  Current  Market  Price),  and of  which  the
denominator  shall be the number of shares of Common  Stock  outstanding  on the
date of issuance of such rights or warrants plus the number of additional shares
of Common Stock offered for  subscription or purchase.  Such adjustment shall be
made  successively  whenever any such rights or warrants  are issued,  and shall
become  effective  immediately  after such  record  date.  Except as provided in
subsection (f) below, in determining  whether any rights or warrants entitle the
holders to  subscribe  for or purchase  shares of Common Stock at less than such
Current Market Price,  and in determining  the aggregate  offering price of such
shares of Common  stock,  there shall be taken into  account  any  consideration
received  by the  Company  for  such  rights  or  warrants,  the  value  of such
consideration, if other than cash, to be determined by the Board of Directors of
the  Company  whose  determination  shall  be  conclusive  and  described  in  a
certificate filed with the Trustee.  Upon the expiration of any right or warrant
to purchase  Common Stock the issuance of which resulted in an adjustment in the
conversion  price pursuant to this  subsection (b), if any such right or warrant
shall  expire and shall not have been  exercised,  the  conversion  price  shall
immediately  upon such  expiration be recomputed to the  conversion  price which
would have been in effect had the adjustment of the  conversion  price made upon
the  issuance of such rights or warrants  been made on the basis of offering for
subscription  or purchase  only that number of shares of Common  Stock  actually
purchased upon the exercise of such rights or warrants actually exercised.

                                       49



     (c) In case the Company shall distribute to all holders of its Common Stock
any  shares  of  Capital  Stock of the  Company  (other  than  Common  Stock) or
evidences  of its  indebtedness  or assets  (excluding  cash  dividends or other
distributions  to the extent  paid from  retained  earnings  of the  Company) or
rights or warrants to subscribe for or purchase any of its securities (excluding
those  referred  to in  subsection  (b)  above),  then,  except as  provided  in
subsection (f) below,  in each such case the conversion  price shall be adjusted
so that the same shall equal the price  determined by multiplying the conversion
price in effect  immediately  before the date of such distribution by a fraction
of which the numerator  shall be the Current  Market Price per share (as defined
in subsection (f) below) of the Common Stock on the record date mentioned  below
less the fair market  value on such record date (as  determined  by the Board of
Directors of the Company, whose determination shall be conclusive, and described
in a certificate  filed with the Trustee) of the portion of the Capital Stock or
assets or evidences of indebtedness so distributed or of such rights or warrants
applicable to one share of Common Stock, and the denominator shall be the market
price per share (as defined in subsection (f) below) of the Common Stock on such
record date. Such adjustment shall become effective immediately after the record
date  for  the   determination   of  stockholders   entitled  to  received  such
distribution, except as provided in subsection (f) below.

     (d) In case the Company shall, by dividend or otherwise,  distribute to all
holders of its Common Stock cash in an aggregate amount that,  combined together
with (1) the aggregate  amount of any other  distributions to all holders of its
Common Stock made exclusively in cash within the 12 months preceding the date of
payment of such  distribution and in respect of which no adjustment  pursuant to
this paragraph (d) has been made and (2) the aggregate of any cash plus the fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive and described in a Board  Resolution) of consideration  payable in
respect of any tender offer by the Company or any of its Subsidiaries for all or
any portion of the Common Stock  concluded  within the 12 months  preceding  the
date of payment  of such  distribution  and in  respect  of which no  adjustment
pursuant to  paragraph  (e) of this  Section  has been made,  exceeds 10% of the
product of the Current  Market  Price per share of the Common  Stock on the date
for the  determination  of holders of shares of Common Stock entitled to receive
such distribution times the number of shares of Common Stock outstanding on such
date,  then, and in each such case,  immediately  after the close of business on
such date for  determination,  the conversion price shall be reduced so that the
same shall equal the price  determined by multiplying  the  conversion  price in
effect  immediately  before  the  close  of  business  on  the  date  fixed  for
determination  of the  stockholders  entitled to receive such  distribution by a
fraction (i) the  numerator of which shall be equal to the Current  Market Price
per share of the Common Stock on the date fixed for such  determination  less an
amount equal to the quotient of (x) the excess of such combined amount over such
10% and (y) the number of shares of Common  Stock  outstanding  on such date for
determination  and (ii) the  denominator  of which shall be equal to the Current
Market Price per share of the Common Stock on such date for determination.

     (e) In case a tender offer made by the Company or any Subsidiary for all or
any portion of the Common  Stock shall  expire and such tender offer (as amended
at the time of the expiration thereof) shall require the payment to stockholders
(based on the acceptance (up to any maximum specified in the terms of the tender
offer) of  Purchase  Shares (as  defined  below) of an  aggregate  consideration
having a fair market value (as determined by the Board of Directors,

053113\1008\02764\979QGT85.OTH
                                       50



     whose   determination   shall  be  conclusive  and  described  in  a  Board
Resolution)  that combined  together with (1) the aggregate of the cash plus the
fair market value (as determined by the Board of Directors,  whose determination
shall be conclusive and described in a Board Resolution) as of the expiration of
such  tender  offer,  of  consideration  payable in respect of any other  tender
offer,  by the  Company or any  Subsidiary  for all or any portion of the Common
Stock  expiring  within the 12 months  preceding  the  expiration of such tender
offer and in respect of which no adjustment  pursuant to this  paragraph (e) has
been made and (2) the  aggregate  amount of any  distributions to all holders of
the Company's  Common Stock made  exclusively in cash within 12 months preceding
the  expiration  of such  tender  offer and in  respect  of which no  adjustment
pursuant to  paragraph  (d) of this  Section  has been made,  exceeds 10% of the
product of the Current Market Price per share of the Common Stock as of the last
time (the  "Expiration  Time")  tenders  could have been made  pursuant  to such
tender  offer (as it may be amended)  times the number of shares of Common Stock
outstanding (including any tendered shares) on the Expiration Time, then, and in
each such case,  immediately before the opening of business on the day after the
date of the Expiration  Time, the conversion price shall be adjusted so that the
same shall equal the price  determined by multiplying  the  conversion  price in
effect  immediately  before close of business on the date of the Expiration Time
by a fraction  (i) the  numerator  of which shall be equal to (A) the product of
(1) the Current  Market  Price per share of the Common  Stock on the date of the
Expiration  Time and  (2) the  number  of shares  of  Common  Stock  outstanding
(including any tendered  shares) on the Expiration  Time, less (B) the amount of
cash plus the fair market  value  (determined  as  aforesaid)  of the  aggregate
consideration payable to stockholders based on the acceptance (up to any maximum
specified in the terms of the tender  offer) of Purchased  Shares,  and (ii) the
denominator  of which shall be equal to the  product of (A) the  Current  Market
Price per share of the Common Stock as of the Expiration Time and (B) the number
of shares of Common Stock outstanding  (including any tendered shares) as of the
Expiration Time less the number of all shares validly tendered and not withdrawn
as of the Expiration Time (the shares deemed so accepted up to any such maximum,
being referred to as the "Purchased Shares").

     (f) No adjustment  in the  conversion  price shall be required  unless such
adjustment  would  require an increase or decrease of at least 1% in such price;
provided,  however,  that any adjustments which by reason of this subsection (f)
are not  required to be made shall be carried  forward and taken into account in
any subsequent adjustment.  All calculations under this Article 10 shall be made
by the  Company  and shall be made to the  nearest  cent or to the  nearest  one
hundredth of a share, as the case may be.  Anything in this  Section 10.5 to the
contrary notwithstanding,  the Company shall be entitled to make such reductions
in the conversion price, in addition to those required by this Section 10.5,  as
it in its  discretion  shall  determine  to be advisable in order that any stock
dividends,  subdivision of shares,  distribution  of rights to purchase stock or
securities, or a distribution of securities convertible into or exchangeable for
stock hereafter made by the Company to its stockholders shall not be taxable.

     (g)  Whenever  the  conversion  price is adjusted as herein  provided,  the
Company shall promptly file with the Trustee and any conversion agent other than
the Trustee an Officers'  Certificate  setting forth the conversion  price after
such  adjustment and setting forth a brief statement of the facts requiring such
adjustment.  Promptly  after  delivery of such  certificate,  the Company  shall
prepare a notice of such adjustment of the conversion price setting forth the

053113\1008\02764\979QGT85.OTH
                                       51



     adjusted  conversion  price and the date on which such  adjustment  becomes
effective and shall mail or cause to be mailed such notice of such adjustment of
the  conversion  price  to the  Holder  of each  Security  at his  last  address
appearing  on  the  Security  register  provided  for  in  Section 2.3  of  this
Indenture.

     (h) In any case in which  this  Section 10.5  provides  that an  adjustment
shall become effective immediately after a record date for an event, the Company
may defer  until the  occurrence  of such event (i) issuing to the Holder of any
Security  converted  after such  record date and before the  occurrence  of such
event the  additional  shares of Common Stock  issuable upon such  conversion by
reason of the adjustment  required by such event over and above the Common Stock
issuable upon such  conversion  before giving effect to such adjustment and (ii)
paying to such  Holder any amount in cash in lieu of any  fraction  pursuant  to
Section 10.3.

     Section 10.6 Effect of Reclassification, Consolidation, Merger or Sale.

     If any of the following events occur,  namely (i) any  reclassification  or
change of outstanding  shares of Common Stock (other than a change in par value,
or from par value to no par value,  or from no par value to par  value,  or as a
result of a  subdivision  or  combination),  (ii) any  consolidation,  merger or
combination of the Company with another corporation as a result of which holders
of Common Stock shall be entitled to receive stock, securities or other property
or assets (including cash) with respect to or in exchange for such Common Stock,
or (iii) any sale or conveyance of the  properties and assets of the Company as,
or substantially  as, an entirety to any other  corporation as a result of which
holders of Common Stock shall be entitled to receive stock,  securities or other
property or assets  (including  cash) with  respect to or in  exchange  for such
Common  Stock shall  occur,  then the  Company or the  successor  or  purchasing
corporation,  as the case may be, shall execute with the Trustee a  supplemental
indenture  (which shall  conform to the TIA as in force at the date of execution
of  such  supplemental   indenture)   providing  that  each  Security  shall  be
convertible  into the kind and amount of shares of stock and other securities or
property  or assets  (including  cash)  receivable  upon such  reclassification,
change, consolidation,  merger, combination, sale or conveyance by a holder of a
number of shares of Common Stock  issuable upon  conversion  of such  Securities
immediately  before  such  reclassification,   change,  consolidation,   merger,
combination,  sale or conveyance.  Such supplemental indenture shall provide for
adjustments  which shall be as nearly  equivalent as may be  practicable  to the
adjustments provided for in this Article.

     The  Company  shall  cause  notice of the  execution  of such  supplemental
indenture to be mailed to each Holder of Securities, at his address appearing on
the Security register provided for in Section 2.3 of this Indenture.

     The  above  provisions  of  this  Section 10.6  shall  similarly  apply  to
successive reclassifications,  changes,  consolidations,  mergers, combinations,
sales and conveyances.

     Section 10.7 Taxes on Shares Issued.

     The issue of stock  certificates on conversions of Securities shall be made
without charge to the converting  Holder of Securities for any tax in respect of
the issue thereof. The

053113\1008\02764\979QGT85.OTH
                                       52



     Company shall not, however, be required to pay any tax which may be payable
in respect of any  transfer  involved in the issue and  delivery of stock in any
name other than that of the Holder of any  Security  converted,  and the Company
shall not be required to issue or deliver any such stock certificate  unless and
until the person or persons  requesting the issue thereof shall have paid to the
Company the amount of such tax or shall have  established to the satisfaction of
the Company that such tax has been paid.

     Section 10.8  Reservation  of Shares;  Shares to be Fully Paid;  Compliance
with Governmental Requirements; Listing of Common Stock.

     The Company shall use its best efforts,  including  asking its stockholders
to authorize  additional Common Stock to provide,  free from preemptive  rights,
out of its authorized but unissued shares or shares held in treasury, sufficient
shares of Common Stock to provide for the conversion of the Securities from time
to time as such Securities are presented for conversion.

     Before  taking any action  which would  cause an  adjustment  reducing  the
conversion price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Securities,  the Company will take all corporate
action which may, in the opinion of its counsel,  be necessary in order that the
Company  may  validly and  legally  issue  shares of such  Common  Stock at such
adjusted conversion price.

     The Company  covenants  that all shares of Common Stock which may be issued
upon conversion of Securities will upon issue be fully paid and nonassessable by
the Company and free from all taxes, liens and charges with respect to the issue
thereof.

     The Company covenants that if any shares of Common Stock to be provided for
the purpose of conversion of Securities  hereunder require  registration with or
approval  of any  governmental  authority  under any Federal or State law before
such shares may be validly  issued  upon  conversion,  the Company  will in good
faith and as expeditiously as possible  endeavor to secure such  registration or
approval, as the case may be.

     The Company  further  covenants  that if at any time Common  Stock shall be
listed on the American Stock Exchange or any other national  securities exchange
the Company  will,  if  permitted by the rules of such  exchange,  list and keep
listed so long as the  Common  Stock  shall be so listed on such  exchange,  all
Common Stock issuable upon conversion of the Securities.

     Section 10.9 Responsibility of Trustee.

     The Trustee and any other  conversion  agent shall not at any time be under
any duty or  responsibility to any Holder of Securities to determine whether any
facts exist which may require any  adjustment of the  conversion  price or other
adjustment  or with respect to the nature or extent or  calculation  of any such
adjustment when made, or with respect to the method  employed,  herein or in any
supplemental  indenture provided to be employed, in making the same. The Trustee
and any other  conversion  agent shall not be  accountable  with  respect to the
validity or value (or the kind or amount) of any shares of Common  Stock,  or of
any securities or

053113\1008\02764\979QGT85.OTH
                                       53



     property,  which may at any time be issued or delivered upon the conversion
of any  Security;  and  the  Trustee  and any  other  conversion  agent  make no
representations with respect thereto.  Subject to the provisions of Section 7.1,
neither the  Trustee  nor any  conversion  agent  shall be  responsible  for any
failure of the Company to issue,  transfer or deliver any shares of Common Stock
or stock certificates or other securities or property or cash upon the surrender
of any  Security  for the  purpose of  conversion  or to comply  with any of the
duties,   responsibilities  or  covenants  of  the  Company  contained  in  this
Article 10.  Without  limiting  the  generality  of the  foregoing,  neither the
Trustee nor any conversion agent shall be under any  responsibility to determine
the  correctness  of any  provisions  contained  in any  supplemental  indenture
entered into pursuant to  Section 10.6  relating either to the kind or amount of
shares of stock or securities or property (including cash) receivable by Holders
of Securities upon the conversion of their  Securities  after any event referred
to in  Section 10.6 or to any adjustment to be made with respect  thereto,  but,
subject to the  provisions of Section 7.1, may accept as conclusive  evidence of
the correctness of any such provisions,  and shall be protected in relying upon,
the Officers' Certificate (which the Company shall be obligated to file with the
Trustee before the execution of any such  supplemental  indenture)  with respect
thereto.

     Section 10.10 Notice to Holders Before Certain Actions.

                  In case:

     (a) the Company shall declare a dividend (or any other distribution) on its
Common Stock (other than in cash out of retained earnings); or

     (b) the Company  shall  authorize the granting to the holders of its Common
Stock of rights or warrants to subscribe  for or purchase any share of any class
or any other rights or warrants; or

     (c) of any  reclassification of the Common Stock of the Company (other than
a subdivision or combination of its outstanding Common Stock, or a change in par
value, or from par value to no par value, or from no par value to par value), or
of any  consolidation  or merger to which the  Company  is a party and for which
approval  of any  shareholders  of the  Company is  required,  or of the sale or
transfer of all or substantially all of the assets of the Company; or

     (d) of the voluntary or involuntary dissolution,  liquidation or winding-up
of the Company; or

     (e) of an increase in the interest rate on the  Securities  pursuant to the
Registration Rights Agreement,

     the  Company  shall  cause to be filed with the Trustee and to be mailed to
each Holder of Securities at his address  appearing on the  Securities  Register
provided for in  Section 2.3 of this  Indenture,  as promptly as possible but in
any  event  at  least  fifteen  days  before  the  applicable  date  hereinafter
specified,  a notice  stating  (x) the date on which a record is to be taken for
the purpose of such dividend,  distribution or rights, or, if a record is not to
be taken, the date as of which the

                                       54



     holders  of  Common  Stock  of  record  to be  entitled  to such  dividend,
distribution  or  rights  are to be  determined,  or (y) the date on which  such
reclassification,    consolidation,   merger,   sale,   transfer,   dissolution,
liquidation  or winding-up is expected to become  effective or occurring and the
date as of which it is expected  that holders of Common Stock of record shall be
entitled  to  exchange  their  Common  Stock for  securities  or other  property
deliverable upon such reclassification,  consolidation,  merger, sale, transfer,
dissolution,  liquidation  or  winding-up.  Failure to give such notice,  or any
defect  therein,  shall not affect the  legality or  validity of such  dividend,
distribution,   reclassification,   consolidation,   merger,   sale,   transfer,
dissolution, liquidation or winding-up.


                                   ARTICLE XI
                                  SUBORDINATION

     Section 11.1 Agreement to Subordinate.

     The Company agrees,  and each Holder by accepting a Security  agrees,  that
the  indebtedness  evidenced  by the  Securities,  and  any  guarantee  of  that
indebtedness,  is  subordinated  in right of  payment,  to the extent and in the
manner  provided  in this  Article,  to the prior  payment in full of all Senior
Indebtedness,  and that the  subordination  is for the benefit of the holders of
Senior Indebtedness.

     Section 11.2 Certain Definitions.

     "Senior Indebtedness" means:

     (a) the  principal  of,  interest  (including,  to the extent  permitted by

                                       55



     (b)  any   refundings,   refinancings,   renewals  or   extensions  of  any

     Notwithstanding  the  foregoing  (i) if,  by the  terms  of the  instrument
creating or evidencing any indebtedness or obligation referred to in clauses (a)
or (b) above, it is expressly  provided that such  indebtedness or obligation is
not  senior  in  right  of  payment  to the  Securities,  such  indebtedness  or
obligation  shall not be  included  as Senior  Indebtedness,  and (ii) the Notes
shall be, pari passu, in right of payment with the Existing  Debentures,  except
that the Existing  Debentures  have the benefit of  guarantees  by the Company's
Subsidiaries.

     "Representative"  means the indenture  trustee or other  trustee,  agent or
representative for an issue of Senior Indebtedness.

     Section 11.3 Liquidation; Dissolution; Bankruptcy.

     Upon  any  distribution  to  creditors  of the  Company  in a  liquidation,
dissolution  or winding up of the  Company or in a  bankruptcy,  reorganization,
insolvency,  receivership or similar  proceeding  relating to the Company or its
property:

     (1) holders of Senior  Indebtedness shall be entitled to receive payment in
full,  in  cash or in a  manner  satisfactory  to the  holders  of  such  Senior
Indebtedness,  of all Senior  Indebtedness  before  Holders shall be entitled to
receive,  from the Company or from any guarantor of the  Obligations  under this
Indenture  and the Notes,  any payments of  principal of or premium,  if any, or
interest on Securities; and

     (2) until the  Senior  Indebtedness  is paid in full in cash or in a manner
satisfactory  to the holders of such Senior  Indebtedness,  any  distribution to
which Holders would be entitled but for this Article shall be made to holders of
Senior  Indebtedness  as their  interest  may appear,  except  that  Holders may
receive securities that are subordinated to Senior  Indebtedness to at least the
same extent as the Securities.

     A distribution may consist of cash, securities or other property.

     Section 11.4 Company Not to Make  Payments  with Respect to  Securities  in
Certain Circumstances.

     (a)  Upon  the  maturity  of any  Senior  Indebtedness  by  lapse  of time,

thereon and any other  amounts  owing in respect  thereof shall first be paid in
full, or such payment duly provided for in cash or in a manner  satisfactory  to
the holders of such Senior  Indebtedness,  before any payment is made on account
of the  principal  of or premium,  if any, or interest on the  Securities  or to
acquire any of the Securities.


053113\1008\02764\979QGT85.OTH
                                       56



     (b) Upon the  happening  of an event of default (or if any event of default
would  result  upon any payment  upon or with  respect to the  Securities)  with
respect to any Senior  Indebtedness  as such event of default is defined therein
or in the  instrument  under  which it is  outstanding,  permitting  holders  to
accelerate  the maturity  thereof,  and, if the default is other than default in
payment of the principal of, premium, if any, or interest on or any other amount
owing in respect of such Senior Indebtedness,  upon written notice thereof given
to the Company and the  Trustee by the holders of Senior  Indebtedness  or their
Representative,  then,  unless such an event of default shall have been cured or
waived or shall have ceased to exist, no payment shall be made by the Company or
any guarantor  with respect to the principal of or premium,  if any, or interest
on the Securities or to acquire any of the Securities.

     Section 11.5 Acceleration of Securities.

     If payment of the Securities is accelerated because of an Event of Default,
the  Company  shall  promptly  notify  holders  of  Senior  Indebtedness  of the
acceleration.

     Section 11.6 When Distribution Must Be Paid Over.

     If a  distribution  is made to Holders  that,  because of this  Article 11,
should not have been made to them,  the Holders  who  receive  the  distribution
shall  hold it in trust for  holders of Senior  Indebtedness  and pay it over to
them as their interests may appear.

     Section 11.7 Notice by Company.

     The Company shall  promptly  notify the Trustee and the Paying Agent of any
facts  known to the  Company  that  would  cause a payment  of  principal  of or
premium, if any, or interest on the Securities to violate this Article 11.

     Section 11.8 Subrogation.

     After all Senior  Indebtedness is paid in full and until the Securities are
paid in full,  Holders  shall be  subrogated  to the rights of holders of Senior
Indebtedness to receive  distributions  applicable to Senior Indebtedness to the
extent that distributions  otherwise payable to the Holders have been applied to
the payment of Senior Indebtedness. A distribution made under this Article 11 to
holders of Senior  Indebtedness  which otherwise would have been made to Holders
is not, as between the Company and  Holders,  a payment by the Company on Senior
Indebtedness.

     Section 11.9 Relative Rights.

     This  Article 11  defines  the  relative  rights of Holders  and holders of
Senior Indebtedness. Nothing in this Indenture shall:

     (1)  impair,  as between the Company and  Holders,  the  obligation  of the
Company,  which is absolute and unconditional,  to pay principal of and premium,
if any, and interest on the Securities in accordance with their terms;

053113\1008\02764\979QGT85.OTH
                                       57




     (2) affect the  relative  rights of Holders and  creditors  of the Company,
other than holders of Senior  Indebtedness  and any guarantors of the Obligation
under this Indenture and the Notes; or

     (3)  prevent  the  Trustee  or any Holder  from  exercising  its  available
remedies upon a Default, subject to the rights of holders of Senior Indebtedness
to receive distributions otherwise payable to Holders.

     If the Company  fails  because of this  Article 11  to pay  principal of or
premium,  if any, or interest on a Security on the due date,  such failure shall
nevertheless be deemed a Default.

     Section 11.10 Subordination May Not Be Impaired by Company.

     No right of any holder of Senior  Indebtedness to enforce the subordination
of the indebtedness  evidenced by the Securities shall be impaired by any act or
failure to act by the Company or by its failure to comply with the terms of this
Indenture.

     Section 11.11 Distribution or Notice to Representative.

     Whenever  a  distribution  is to be made or a notice  given to  holders  of
Senior Indebtedness,  the distribution may be made and the notice given to their
Representative.

     Section 11.12 Rights of Trustee and Paying Agent.

     Notwithstanding  any  provisions  of this  Indenture to the  contrary,  the
Trustee and any Paying Agent may continue to make payments on the Securities and
shall not at any time be charged with  knowledge  of the  existence of any facts
which would  prohibit  the making of such  payments  until it  receives  written
notice  (received  by a  Responsible  Officer,  in  the  case  of  the  Trustee)
reasonably  satisfactory  to it  that  payments  may  not  be  made  under  this
Article 11 and, before the receipt of any such notice,  the Trustee,  subject to
the  provisions  of  Article  7, and any  agent  shall  be  entitled  to  assume
conclusively  that no such facts exist. The Company,  an Agent, a Representative
or a holder of Senior  Indebtedness  may give the notice.  If an issue of Senior
Indebtedness   has  a   Representative,   only   the   Representative   (or  any
Representative,  if more  than one) may give the  notice  with  respect  to such
Senior Indebtedness.

     The Trustee  shall be  entitled to rely on the  delivery to it of a written
notice by a Person  representing  himself to be a holder of Senior  Indebtedness
(or a  Representative)  to establish that such notice has been given by a holder
of Senior  Indebtedness (or a Representative),  and shall be entitled to rely on
any  written  notice by a Person  representing  himself to be a holder of Senior
Indebtedness  to the  effect  that  such  issue of  Senior  Indebtedness  has no
Representative.

     Any deposit of moneys by the Company  with the Trustee or any Paying  Agent
(whether or not in trust) for the  payment of the  principal  of or premium,  if
any, or interest on, or payment on account of Change in Control, if any, of, any
Securities shall be subject to the

053113\1008\02764\979QGT85.OTH
                                       58



     provisions of this Article 11, except that if, at least three business days
before  the date on which by the terms of this  Indenture  any such  moneys  may
become payable for any purpose (including,  without  limitation,  the payment of
principal of or premium, if any, or interest on any Security), the Trustee shall
not have  received  with respect to such moneys the notice  provided for in this
Section  11.12,  then the Trustee shall have full power and authority to receive
such moneys and to apply the same to the  purpose  for which they were  received
and shall not be affected by any notice to the contrary which may be received by
it  within  three  business  days  before  or  on  or  after  such  date.   This
Section 11.12  shall be  construed  solely for the  benefit of the  Trustee  and
Paying  Agent and shall not  otherwise  affect  the  rights of holders of Senior
Indebtedness.  If the Trustee  determines in good faith that further evidence is
required  with  respect  to  the  right  of  any  Person  as  holder  of  Senior
Indebtedness  to  participate  in any payment or  distribution  pursuant to this
Article 11,  the  Trustee may  request  such  Person to furnish  evidence to the
reasonable  satisfaction  of  the  Trustee  as  to  the  amount  of  the  Senior
Indebtedness held by such Person, the extent to which such person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such  Person  under this  Article  11,  and,  if such  evidence is not
furnished,  the Trustee may defer any  payment to such Person  pending  judicial
determination as to the right of such Person to receive payment.

     The  Trustee  shall not be deemed to owe any  fiduciary  duty to holders of
Senior  Indebtedness  by  virtue  of the  provisions  of  this  Article 11.  The
Trustee's  responsibilities to the holders of Senior Indebtedness are limited to
those set forth in this  Article 11,  and no implied  covenants  or  obligations
shall be read into this  Indenture.  The Trustee  shall not become liable to the
holders  of  Senior  Indebtedness  if it  makes  a  payment  prohibited  by this
Article 11 in good faith.

     The  Trustee  in its  individual  or any  other  capacity  may hold  Senior
Indebtedness  with the same  rights it would  have if it were not  Trustee.  Any
agent may do the same with like rights.

     Section 11.13 Effectuation of Subordination by Trustee.

     Each Holder of Securities,  by acceptance  thereof,  authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effect the subordination provided in this Article 11 and appoints the Trustee
his attorney-in-fact for any and all such purposes.

     Section 1. Interest.  Key Energy Group,  Inc., a Maryland  corporation (the
"Company"),  promises  to pay  interest  on the  principal  amount  of  this  5%
Convertible  Subordinated  Note due  2004  (the  "Note")  at the rate and in the
manner specified below.

     The Company will pay interest semi-annually on September 15 and March 15 of
each year  commencing  March 15, 1998, or if any such day is not a Business Day,
on the next Business Day (each an "Interest  Payment Date") to record holders of
Notes ("Holders") at the close of business on September 1 or March 1 immediately
preceding the applicable Interest Payment Date. A copy of the Indenture (defined
below),  the Registration  Rights  Agreement and all other agreements  affecting
this Note or the Holders may be obtained from the Company upon request.

     Interest  shall be computed on the basis of a 360-day  year  consisting  of
twelve 30-day  months.  Interest shall accrue from the most recent date to which
interest  has been paid or, if no interest  has been paid,  from the date of the
original  issuance of this Note.  To the extent  lawful,  the Company  shall pay
interest on overdue  principal at the rate of 1% per annum in excess of the then
applicable  interest  rate on this  Note;  it  shall  pay  interest  on  overdue
installments of interest (without regard to any applicable grace periods) at the
same rate to the extent lawful.

053113\1008\02764\979QGT85.OTH


     Section 2. Method of Payment.  The Company  shall pay interest on the Notes
(except  defaulted  interest)  to Holders at the close of business on the record
date next preceding the Interest  Payment Date,  even if such Notes are canceled
after such record date and on or before such Interest  Payment Date.  The Holder
hereof must  surrender this Note to a Paying Agent (as defined in the Indenture)
to collect principal  payments.  The Company shall pay principal and interest in
money of the  United  States  that at the time of  payment  is legal  tender for
payment of public and private debts. The Company, however, may pay principal and
interest  by check  payable in such money.  It may mail an  interest  check to a
Holder's registered address.

     Section 3. Paying Agent and Registrar.  Initially, the Trustee shall act as
Paying Agent and Registrar.  The Company may change any Paying Agent,  Registrar
or co-  Registrar  without  notice to any  Holder.  The  Company  and any of its
Subsidiaries may act in any such capacity.

     Section 4.  Indenture.  The Company  issued the Notes  under an  Indenture,
dated as of September 25, 1997 (the "Indenture"), among the Company and American
Stock Transfer & Trust Company, as Trustee. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust  Indenture Act of 1939 (15 U.S. Code  SS 77aaa-77bbbb),  as amended by the
Trust  Indenture  Reform  Act of  1990,  and as in  effect  on the  date  of the
Indenture.  The Notes are subject to all such terms, and Holders are referred to
the  Indenture  and such Act for a  statement  of such  terms.  The terms of the
Indenture shall govern any inconsistencies  between the Indenture and the Notes.
Capitalized  terms used herein that are not  specifically  defined  herein shall
have the meanings set forth in the  Indenture.  The Notes are unsecured  general
obligations  of the  Company  limited to  $216,000,000  in  aggregate  principal
amount.

     Section 5.  Optional  Redemption.  The Company may redeem at any time on or
after  September 15, 2000, all or any portion of the  Securities  outstanding at
the  following  redemption  prices  expressed as a percentage  of the  principal
amount  thereof,  if the  Securities  are redeemed  during the  12-month  period
beginning September 15, of the following years:


Year                                                       Percentage

2000................................................          102.86%

2001................................................          102.14%

2002................................................          101.43%

2003................................................          100.71%

2004................................................           100%



     Section 6.  Redemption  or  Repurchase  at Option of Holder.  If there is a
Change in Control (as defined in the Indenture), the Company will be required to
offer to

                                      A1-4
053113\1008\02764\979QGT85.OTH

     purchase  on  the  Change  in  Control  Payment  Date  (as  defined  in the
Indenture) all outstanding  Notes at 100% of the principal amount thereof,  plus
accrued and unpaid  interest to the date of  purchase.  Holders  whose Notes are
subject  to an offer to  purchase  will  receive an offer to  purchase  from the
Company  prior to any related  Change in Control  Payment  Date and may elect to
have their Notes purchased by completing the form entitled  "Option of Holder to
Elect Purchase" appearing below.

     Section 7. Notice of  Redemption.  Notice of  redemption  will be mailed at
least 30 days but not  more  than 45 days  before  the  redemption  date to each
Holder to be redeemed at its registered  address.  Notes may be redeemed in part
but only in whole multiples of $1,000,  unless all of the Notes held by a Holder
are to be redeemed.  On and after the redemption date, interest ceases to accrue
on Notes or portions of them called for redemption.

     Section 8.  Conversion.  Subject to the  provisions of the  Indenture,  the
Holder  hereof has the right,  at its  option,  at any time on or after 270 days
after the Issue Date and on or before the  maturity,  to convert  the  principal
hereof or any portion of such  principal  that is $1,000 or a multiple  thereof,
into, at the Company's option, (a) cash in an amount equal to the Current Market
Price,  as of the  conversion  date,  of the Common Stock to which the principal
would  otherwise  be  converted,  or (b) that number of shares of the  Company's
Common Stock (as such shares shall then be constituted) obtained by dividing the
principal  amount  of this  Note  or  portion  thereof  to be  converted  by the
conversion  price of $38.50,  or such conversion  price as adjusted from time to
time as provided in the Indenture or (c) a combination  of cash and Common Stock
in  proportions  determined  by the  Company in its sole  discretion;  provided,
however,  that the Company's option to convert the principal into cash or into a
combination of cash and Common Stock,  shall  terminate at the close of business
on the date the Company's charter is amended to increase the number of shares of
authorized  Common Stock to at least that number of shares sufficient to reserve
for the conversion of all the Notes.

     The right to convert  with respect to any Security or portion of a Security
that shall be called for redemption or delivered for repurchase, shall terminate
at the close of business on the date fixed for  redemption  of such  Security or
portion of a Security or the second  trading  day  preceding a Change in Control
Payment  Date,  as the case may be,  unless the Company shall default in payment
due upon redemption or repurchase thereof.

     No  adjustments  in respect of interest or dividends  will be made upon any
conversion;  provided,  however,  that if the  Note  shall  be  surrendered  for
conversion  during the period  from the close of business on any record date for
the payment of interest  to the  opening of business on the  following  interest
payment  date,  this Note (unless it or the portion being  converted  shall have
been called for  redemption on a date in such period) must be  accompanied by an
amount,  in funds  acceptable to the Company,  equal to the interest  payable on
such  interest  payment  date  on  the  principal  amount  being  converted.  No
fractional shares will be issued upon any conversion,  but an adjustment in cash
shall be made,  as provided in the  Indenture,  in respect of any  fraction of a
share which would  otherwise be issuable upon the surrender of any Note or Notes
for  conversion.  A holder of Notes is not entitled to any rights of a holder of
Common Stock until such holder has converted his Notes to Common

                                      A1-5
053113\1008\02764\979QGT85.OTH

     Stock,  and only to the  extent  such Notes are to have been  converted  to
Common Stock under the Indenture.

     The  conversion  price is subject to adjustment in accordance  with Section
10.5 of the Indenture.

     Section  9.  Subordination.  The  Securities  are  subordinated  to  Senior
Indebtedness  (as  defined  in the  Indenture).  To the extent  provided  in the
Indenture,  Senior  Indebtedness  must be paid before the Securities may be paid
either by the Company or any guarantor of  Obligations  under this Indenture and
the Note. The Company agrees, and each Holder by accepting a Security agrees, to
the  subordination  provisions  contained in the  Indenture and  authorizes  the
Trustee to give effect to such provisions,  and each Holder appoints the Trustee
his  attorney-in-fact  for any and all such  purposes.  This Note  shall be pari
passu,  in all  respects,  with  the  Existing  Debentures  (as  defined  in the
Indenture),  except that the Existing  Debentures have the benefit of guarantees
by the Company's Subsidiaries.

     Section 10.  Denominations,  Transfer,  Exchange.  The Notes are  initially
issued in global  form.  The  global  Note  represents  such of the  outstanding
Securities as shall be specified  therein or endorsed thereon in accordance with
the Indenture.  The definitive Securities are in registered form without coupons
in denominations of $1,000 and whole multiples of $1,000.  The transfer of Notes
may be registered and Notes may be exchanged as provided in the  Indenture.  The
Registrar and the Trustee may require a Holder,  among other things,  to furnish
appropriate  endorsements  and transfer  documents and to pay any taxes and fees
required by law or permitted by the  Indenture.  The Registrar need not exchange
or  register  the  transfer  of any  Note or  portion  of an Note  selected  for
redemption. Also, it need not exchange or register the transfer of any Notes for
a period of 15 days before a selection of Notes to be redeemed.

     Section 11. Persons Deemed  Owners.  Before due  presentment to the Trustee
for  registration  of the transfer of this Note, the Trustee,  any Agent and the
Company may deem and treat the person in whose name this Note is  registered  as
its  absolute  owner for the purpose of  receiving  payment of  principal of and
interest on this Note and for all other purposes whatsoever, whether or not this
Note is overdue,  and neither the  Trustee,  any Agent nor the Company  shall be
affected by notice to the contrary.  The  registered  holder of an Note shall be
treated as its owner for all purposes.

     Section 12.  Amendments  and Waivers.  Subject to certain  exceptions,  the
Indenture or the Securities may be amended with the consent of the Holders of at
least a majority in principal amount of the then outstanding Securities, and any
existing  default  (except a payment  default) may be waived with the consent of
the  holders  of  a  majority  in  principal  amount  of  the  then  outstanding
Securities.  Without the consent of any Holder,  the Indenture or the Securities
may be amended to cure any ambiguity,  defect or  inconsistency,  to provide for
assumption of Company  obligations to Holders,  to make any change that does not
adversely  affect the rights of any Holder,  to provide  for any  uncertificated
Notes in addition to certificated  Notes, or to comply with  requirements of the
Commission  in order to effect or maintain the  qualification  of the  Indenture
under the TIA.

053113\1008\02764\979QGT85.OTH

     Section 13. Defaults and Remedies.  Events of default  include:  default in
payment  of  interest  on the  Securities  for 30 days;  default  in  payment of
principal of or premium on the Securities  when due;  failure by the Company for
60 days after notice to it to comply with its agreements in the Indenture or the
Securities;  defaults under and acceleration  before express maturity of certain
other Indebtedness that aggregates  $25,000,000 or more; certain final judgments
which  remain  undischarged  if the  aggregate  of all  such  judgments  exceeds
$25,000,000 or more;  certain final judgments  which remain  undischarged if the
aggregate  of all such  judgments  exceeds  $25,000,000;  and certain  events of
bankruptcy or insolvency.  If an Event of Default occurs and is continuing,  the
Trustee  or  the  Holders  of at  least  25% in  principal  amount  of the  then
outstanding  Securities  may  declare all the  Securities  to be due and payable
immediately, except that in the case of an Event of Default arising from certain
events of bankruptcy or insolvency,  all outstanding  Securities  become due and
payable  immediately  without  further  action  or  notice  and all  outstanding
Securities,  and  all  Obligations  and  Claims  with  respect  thereto,  become
immediately  due and  payable.  Holders  may not enforce  the  Indenture  or the
Securities  except  as  provided  in the  Indenture.  The  Trustee  may  require
indemnity satisfactory to it before it enforces the Indenture or the Securities.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding  Securities may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders notice of any continuing default
(except a default in payment of principal or  interest)  if it  determines  that
withholding  notice is in their  interests.  The Company  must furnish an annual
compliance certificate to the Trustee.

     Section 14. Trustee Dealings with Company. The Trustee under the Indenture,
in its  individual or any other  capacity,  may make loans to,  accept  deposits
from, and perform services for the Company or its Affiliates,  and may otherwise
deal with the Company or its  Affiliates,  as if it were not Trustee;  provided,
however,  that if the Trustee acquires any conflicting  interest as described in
the Trust Indenture Act, it must eliminate such conflict or resign.

     Section 15. No Recourse  Against Others.  No director,  officer,  employee,
agent,  manager,  stockholder or other  Affiliates of the Company shall have any
liability  for  any  obligations  of  the  Company  under  the  Securities,  the
Indenture,  or for any  claim  based  on,  in  respect  of or by  reason of such
obligations  or their  creation.  Each  Holder by  accepting  a Note  waives and

     Section 20. Interest.  Key Energy Group, Inc., a Maryland  corporation (the
"Company"),  promises  to pay  interest  on the  principal  amount  of  this  5%
Convertible  Subordinated  Note due  2004  (the  "Note")  at the rate and in the
manner specified below.

     The Company will pay interest semi-annually on September 15 and March 15 of
each year  commencing  March 15, 1998, or if any such day is not a Business Day,
on the next Business Day (each an "Interest  Payment Date") to record holders of
Notes ("Holders") at the close of business on September 1 or March 1 immediately
preceding the applicable Interest Payment Date. A copy of the Indenture (defined
below),  the Registration  Rights  Agreement and all other agreements  affecting
this Note or the Holders may be obtained from the Company upon request.

     Interest  shall be computed on the basis of a 360-day  year  consisting  of
twelve 30-day  months.  Interest shall accrue from the most recent date to which
interest  has been paid or, if no interest  has been paid,  from the date of the
original  issuance of this Note.  To the extent  lawful,  the Company  shall pay
interest on overdue  principal at the rate of 1% per annum in excess of the then
applicable  interest  rate on this  Note;  it  shall  pay  interest  on  overdue
installments of interest (without regard to any applicable grace periods) at the
same rate to the extent lawful.

     Section 1. Method of Payment.  The Company  shall pay interest on the Notes
(except  defaulted  interest)  to Holders at the close of business on the record
date next preceding the Interest  Payment Date,  even if such Notes are canceled
after such record date and on or before such Interest  Payment Date.  The Holder
hereof must  surrender this Note to a Paying Agent (as defined in the Indenture)
to collect principal  payments.  The Company shall pay principal and interest in
money of the  United  States  that at the time of  payment  is legal  tender for
payment of public and private debts. The Company, however, may pay principal and
interest  by check  payable in such money.  It may mail an  interest  check to a
Holder's registered address.

     Section 2. Paying Agent and Registrar.  Initially, the Trustee shall act as
Paying Agent and Registrar.  The Company may change any Paying Agent,  Registrar
or co-  Registrar  without  notice to any  Holder.  The  Company  and any of its
Subsidiaries may act in any such capacity.

     Section 3.  Indenture.  The Company  issued the Notes  under an  Indenture,
dated as of September 25, 1997 (the "Indenture"), among the Company and American
Stock Transfer & Trust Company, as Trustee. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust  Indenture Act of 1939 (15 U.S. Code  SS 77aaa-77bbbb),  as amended by the
Trust  Indenture  Reform  Act of  1990,  and as in  effect  on the  date  of the
Indenture.  The Notes are subject to all such terms, and Holders are referred to
the  Indenture  and such Act for a  statement  of such  terms.  The terms of the
Indenture shall govern any inconsistencies  between the Indenture and the Notes.
Capitalized  terms used herein that are not  specifically  defined  herein shall
have the meanings set forth in the  Indenture.  The Notes are unsecured  general
obligations  of the  Company  limited to  $216,000,000  in  aggregate  principal
amount.

after  September 15, 2000, all or any portion of the  Securities  outstanding at
the  following  redemption  prices  expressed as a percentage  of the  principal
amount  thereof,  if the  Securities  are redeemed  during the  12-month  period
beginning September 15, of the following years:


Year                                                            Percentage

2003.....................................................          100.71%

2004.....................................................           100%



     Section 5.  Redemption  or  Repurchase  at Option of Holder.  If there is a
Change in Control (as defined in the Indenture), the Company will be required to
offer to  purchase  on the Change in  Control  Payment  Date (as  defined in the
Indenture) all outstanding  Notes at 100% of the principal amount thereof,  plus
accrued and unpaid  interest to the date of  purchase.  Holders  whose Notes are
subject  to an offer to  purchase  will  receive an offer to  purchase  from the
Company  prior to any related  Change in Control  Payment  Date and may elect to
have their Notes purchased by completing the form entitled  "Option of Holder to
Elect Purchase" appearing below.

     Section 6. Notice of  Redemption.  Notice of  redemption  will be mailed at
least 30 days but not  more  than 45 days  before  the  redemption  date to each
Holder to be redeemed at its registered  address.  Notes may be redeemed in part
but only in whole multiples of $1,000,  unless all of the Notes held by a Holder
are to be redeemed.  On and after the redemption date, interest ceases to accrue
on Notes or portions of them called for redemption.

     Section 7.  Conversion.  Subject to the  provisions of the  Indenture,  the
Holder  hereof has the right,  at its  option,  at any time on or after 270 days
after the Issue Date and on or before the  maturity,  to convert  the  principal
hereof or any portion of such  principal  that is $1,000 or a multiple  thereof,
into, at the Company's option, (a) cash in an amount equal to the Current Market
Price,  as of the  conversion  date,  of the Common Stock to which the principal
would  otherwise  be  converted,  or (b) that number of shares of the  Company's
Common Stock (as such shares shall then be constituted) obtained by dividing the
principal  amount  of this  Note  or  portion  thereof  to be  converted  by the
conversion  price of $38.50,  or such conversion  price as adjusted from time to
time as provided in the Indenture or (c) a combination  of cash and Common Stock
in  proportions  determined  by the  Company in its sole  discretion;  provided,
however,  that the Company's option to convert the principal into cash or into a
combination of cash and Common Stock,  shall  terminate at the close of business
on the date the Company's charter is amended to increase the number of shares of

 
053113\1008\02764\979QGT85.OTH
                                      A2-5

     authorized  Common  Stock to at least that number of shares  sufficient  to
reserve for the conversion of all the Notes.

     The right to convert  with respect to any Security or portion of a Security
that shall be called for redemption or delivered for repurchase, shall terminate
at the close of business on the date fixed for  redemption  of such  Security or
portion of a Security or the second  trading  day  preceding a Change in Control
Payment  Date,  as the case may be,  unless the Company shall default in payment
due upon redemption or repurchase thereof.

     No  adjustments  in respect of interest or dividends  will be made upon any
conversion;  provided,  however,  that if the  Note  shall  be  surrendered  for
conversion  during the period  from the close of business on any record date for
the payment of interest  to the  opening of business on the  following  interest
payment  date,  this Note (unless it or the portion being  converted  shall have
been called for  redemption on a date in such period) must be  accompanied by an
amount,  in funds  acceptable to the Company,  equal to the interest  payable on
such  interest  payment  date  on  the  principal  amount  being  converted.  No
fractional shares will be issued upon any conversion,  but an adjustment in cash
shall be made,  as provided in the  Indenture,  in respect of any  fraction of a
share which would  otherwise be issuable upon the surrender of any Note or Notes
for  conversion.  A holder of Notes is not entitled to any rights of a holder of
Common Stock until such holder has converted his Notes to Common Stock, and only
to the extent such Notes are to have been  converted  to Common  Stock under the
Indenture.

     The  conversion  price is subject to adjustment in accordance  with Section
10.5 of the Indenture.

     Section  8.  Subordination.  The  Securities  are  subordinated  to  Senior
Indebtedness  (as  defined  in the  Indenture).  To the extent  provided  in the
Indenture,  Senior  Indebtedness  must be paid before the Securities may be paid
either by the Company or any guarantor of  Obligations  under this Indenture and
the Note. The Company agrees, and each Holder by accepting a Security agrees, to
the  subordination  provisions  contained in the  Indenture and  authorizes  the
Trustee to give effect to such provisions,  and each Holder appoints the Trustee
his  attorney-in-fact  for any and all such  purposes.  This Note  shall be pari
passu,  in all  respects,  with  the  Existing  Debentures  (as  defined  in the
Indenture),  except that the Existing  Debentures have the benefit of guarantees
by the Company's Subsidiaries.

     Section  9.  Denominations,  Transfer,  Exchange.  The Notes are  initially
issued in global  form.  The  global  Note  represents  such of the  outstanding
Securities as shall be specified  therein or endorsed thereon in accordance with
the Indenture.  The definitive Securities are in registered form without coupons
in denominations of $1,000 and whole multiples of $1,000.  The transfer of Notes
may be registered and Notes may be exchanged as provided in the  Indenture.  The
Registrar and the Trustee may require a Holder,  among other things,  to furnish
appropriate  endorsements  and transfer  documents and to pay any taxes and fees
required by law or permitted by the  Indenture.  The Registrar need not exchange
or  register  the  transfer  of any  Note or  portion  of an Note  selected  for
redemption. Also, it need not exchange or register the transfer of any Notes for
a period of 15 days before a selection of Notes to be redeemed.

     Section 10. Persons Deemed  Owners.  Before due  presentment to the Trustee
for  registration  of the transfer of this Note, the Trustee,  any Agent and the
Company may deem and treat the person in whose name this Note is  registered  as
its  absolute  owner for the purpose of  receiving  payment of  principal of and
interest on this Note and for all other purposes whatsoever, whether or not this
Note is overdue,  and neither the  Trustee,  any Agent nor the Company  shall be
affected by notice to the contrary.  The  registered  holder of an Note shall be
treated as its owner for all purposes.

     Section 11.  Amendments  and Waivers.  Subject to certain  exceptions,  the
Indenture or the Securities may be amended with the consent of the Holders of at
least a majority in principal amount of the then outstanding Securities, and any
existing  default  (except a payment  default) may be waived with the consent of
the  holders  of  a  majority  in  principal  amount  of  the  then  outstanding
Securities.  Without the consent of any Holder,  the Indenture or the Securities
may be amended to cure any ambiguity,  defect or  inconsistency,  to provide for
assumption of Company  obligations to Holders,  to make any change that does not
adversely  affect the rights of any Holder,  to provide  for any  uncertificated
Notes in addition to certificated  Notes, or to comply with  requirements of the
Commission  in order to effect or maintain the  qualification  of the  Indenture
under the TIA.

     Section 12. Defaults and Remedies.  Events of default  include:  default in
payment  of  interest  on the  Securities  for 30 days;  default  in  payment of
principal of or premium on the Securities  when due;  failure by the Company for
60 days after notice to it to comply with its agreements in the Indenture or the
Securities;  defaults under and acceleration  before express maturity of certain
other Indebtedness that aggregates  $25,000,000 or more; certain final judgments
which  remain  undischarged  if the  aggregate  of all  such  judgments  exceeds
$25,000,000 or more;  certain final judgments  which remain  undischarged if the
aggregate  of all such  judgments  exceeds  $25,000,000;  and certain  events of
bankruptcy or insolvency.  If an Event of Default occurs and is continuing,  the
Trustee  or  the  Holders  of at  least  25% in  principal  amount  of the  then
outstanding  Securities  may  declare all the  Securities  to be due and payable
immediately, except that in the case of an Event of Default arising from certain
events of bankruptcy or insolvency,  all outstanding  Securities  become due and
payable  immediately  without  further  action  or  notice  and all  outstanding
Securities,  and  all  Obligations  and  Claims  with  respect  thereto,  become
immediately  due and  payable.  Holders  may not enforce  the  Indenture  or the
Securities  except  as  provided  in the  Indenture.  The  Trustee  may  require
indemnity satisfactory to it before it enforces the Indenture or the Securities.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding  Securities may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders notice of any continuing default
(except a default in payment of principal or  interest)  if it  determines  that
withholding  notice is in their  interests.  The Company  must furnish an annual
compliance certificate to the Trustee.

     Section 13. Trustee Dealings with Company. The Trustee under the Indenture,
in its  individual or any other  capacity,  may make loans to,  accept  deposits
from, and perform services for the Company or its Affiliates,  and may otherwise
deal with the Company or its  Affiliates,  as if it were not Trustee;  provided,
however,  that if the Trustee acquires any conflicting  interest as described in
the Trust Indenture Act, it must eliminate such conflict or resign.

     Section 14. No Recourse  Against Others.  No director,  officer,  employee,
agent,  manager,  stockholder or other  Affiliates of the Company shall have any
liability  for  any  obligations  of  the  Company  under  the  Securities,  the
Indenture,  or for any  claim  based  on,  in  respect  of or by  reason of such
obligations  or their  creation.  Each  Holder by  accepting  a Note  waives and
releases  all  such   liability.   The  waiver  and  release  are  part  of  the
consideration for the issuance of the Notes.

     Section   15.   Authentication.   This  Note  shall  not  be  valid   until
authenticated by the manual signature of the Trustee or an authenticating agent.

     Section 16. Abbreviations.  Customary abbreviations may be used in the name
of a Holder or an assignee,  such as: TEN COM (= tenants in common),  TEN ENT (=
tenants by the  entireties),  JT TEN (= joint tenants with right of survivorship
and not as tenants in common),  CUST = Custodian),  and U/G/M/A (= Uniform Gifts
to Minors Act).

     Section 17. CUSIP Numbers. Pursuant to a recommendation  promulgated by the
Committee on Uniform Security Identification  Procedures, the Company has caused
CUSIP  numbers to be printed on the Notes and has  directed  the  Trustee to use
CUSIP  numbers  in  notices  of  redemption  as a  convenience  to  Holders.  No
representation  is made as to the accuracy of such numbers  either as printed on
the Notes or as contained in any notice of redemption and reliance may be placed
only on the other identification number placed thereon.

     Section 18. Additional Rights of Holders of Transfer Restricted Securities.
In addition to the rights provided to Holders of Securities under the Indenture,
Holders of Transferred Restricted Securities shall have all the rights set forth
in the Registration  Rights  Agreement  referred to in the Indenture and certain
other agreements executed and delivered in connection therewith.

     The Company  will  furnish to any Holder upon  written  request and without
charge a copy of the Indenture. Request may be made to:

and expenses of attorneys, consultants and experts (collectively, the ADamages@)

from or relate to any breach by either of the Shareholders of (or the failure of
either  of  the  Shareholders  to  perform)  their  respective  representations,
warranties,  covenants  or  agreements  in this  Agreement  or in any  schedule,
certificate,  exhibit or other  instrument  delivered  to Buyer by either of the
Shareholders under this Agreement.

     4.2  Indemnification  by Buyer4.2  Indemnification by Buyer. In addition to
any other remedies available to the Shareholders under this Agreement, or at law

     4.3. Indemnification Procedure4.3.  Indemnification Procedure. In the event
that any party hereto discovers or otherwise becomes aware of an indemnification
claim arising under Section 4.1 of this Agreement,  such indemnified party shall
give written notice to the  indemnifying  party,  specifying such claim, and may
thereafter  exercise any remedies  available to such party under this Agreement;
provided,  however,  that the failure of any indemnified party to give notice as
provided  herein  shall not relieve the  indemnifying  party of any  obligations
hereunder,  to the extent the  indemnifying  party is not materially  prejudiced
thereby.  Further,  promptly after receipt by an indemnified  party hereunder of
written notice of the  commencement  of any action or proceeding with respect to
which a claim for  indemnification  may be made  pursuant to Section 4.1 hereof,
such  indemnified  party  shall,  if a claim in  respect  thereof  is to be made
against  any  indemnifying  party,  give  written  notice  to the  latter of the
commencement  of  such  action;  provided,  however,  that  the  failure  of any
indemnified  party to give  notice as  provided  herein  shall not  relieve  the
indemnifying party of any obligations hereunder,  to the extent the indemnifying
party is not materially  prejudiced  thereby. In case any such action is brought
against an  indemnified  party,  the  indemnifying  party  shall be  entitled to
participate  in and to  assume  the  defense  thereof,  jointly  with any  other
indemnifying  party  similarly  notified,  to the extent that it may wish,  with
counsel reasonably satisfactory to such indemnified party, and after such notice
from the  indemnifying  party to such  indemnified  party of its  election so to
assume the defense thereof,  the indemnifying  party shall not be liable to such
indemnified party for any legal or other expenses  subsequently  incurred by the
latter in connection with the defense thereof unless the indemnifying  party has
failed to assume  the  defense of such  claim and to employ  counsel  reasonably
satisfactory to such indemnified person. As indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld or delayed.

or in  equity,  Buyer  shall  indemnify,  defend and hold  harmless  each of the
Shareholders  against  and  with  respect  to any  and  all  Damages  that  such
indemnitees  shall incur or suffer,  which  arise,  result from or relate to any
breach  of,  or  failure  by  Buyer  to  perform,  any of  its  representations,
warranties,  covenants  or  agreements  in this  Agreement  or in any  schedule,
certificate, exhibit or other instrument furnished or delivered to either of the
Shareholders by or on behalf of Buyer under this Agreement.

     4.3. Indemnification Procedure4.3.  Indemnification Procedure. In the event
that any party hereto discovers or otherwise becomes aware of an indemnification
claim arising under this Article ?,  such  indemnified  party shall give written
notice to the  indemnifying  party,  specifying  such claim,  and may thereafter
exercise any remedies  available to such party under this  Agreement;  provided,
however,  that the failure of any  indemnified  party to give notice as provided
herein shall not relieve the indemnifying party of any obligations hereunder, to
the extent the indemnifying party is not materially prejudiced thereby. Further,
promptly  after receipt by an indemnified  party  hereunder of written notice of
the  commencement  of any action or proceeding with respect to which a claim for
indemnification  may be made pursuant to this Article ?,  such indemnified party
shall,  if a claim in respect  thereof is to be made  against  any  indemnifying
party,  give written  notice to the latter of the  commencement  of such action;
provided,  however,  that the failure of any indemnified party to give notice as
provided  herein  shall not relieve the  indemnifying  party of any  obligations
hereunder,  to the extent the  indemnifying  party is not materially  prejudiced
thereby.  In case any such action is brought against an indemnified  party,  the
indemnifying party shall be entitled to participate in and to assume the defense
thereof,  jointly with any other indemnifying party similarly  notified,  to the
extent  that  it  may  wish,  with  counsel  reasonably   satisfactory  to  such
indemnified  party,  and after such notice from the  indemnifying  party to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in  the  same  jurisdiction   arising  out  of  the  same  general  allegations.
Notwithstanding any of the foregoing to the contrary, the indemnified party will
be  entitled  to select its own  counsel  and  assume the  defense of any action
brought against it if the indemnifying  party fails to select counsel reasonably
satisfactory to the indemnified  party,  the expenses of such defense to be paid
by the indemnifying  party. No indemnifying  party shall consent to entry of any
judgment  or enter  into any  settlement  with  respect to a claim  without  the
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld,  or unless such  judgment or settlement  includes as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability with respect to such claim. No indemnified party
shall consent to entry of any judgment or enter into any  settlement of any such
action, the defense of which has been assumed by an indemnifying party,  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld or delayed.
