            WEATHERFORD INTERNATIONAL INCORPORATED AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) The consolidated financial statements of Weatherford International
Incorporated and its subsidiaries (the "Company" or "Weatherford") included
herein have been prepared by the Company, without audit, pursuant to the rules
and regulations of the Securities and Exchange Commission. In the opinion of
management, the information furnished reflects all adjustments, consisting only
of normal recurring adjustments, which are necessary for a fair presentation of
the results of the interim periods. Certain information and footnote disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to such
rules and regulations. However, the Company believes that the disclosures are
adequate to make the information presented not misleading.

    Certain reclassifications were made to previously reported amounts in the
consolidated financial statements and notes to make them consistent with the
current presentation format.

    It is suggested that these financial statements be read in conjunction with
the financial statements and the notes thereto included in the Company's Annual
Report on Form 10-K for the year ended December 31, 1994.  No significant
accounting changes have occurred during the nine months ended September 30,
1995. Subsequent to September 30, 1995, the Company completed a significant 
merger accounted for as a pooling of interests. See Note 5.

(2) INCOME PER COMMON AND COMMON EQUIVALENT SHARE. Income per common and common
equivalent share is computed on the basis of the weighted average number of
shares of common stock and common stock equivalents (if dilutive) outstanding
during the respective periods. Fully diluted earnings per share are equal to
primary earnings per share in all periods presented.

(3)  INVENTORIES.  Consolidated net inventories consist of the following (in
thousands):

(5) SUBSEQUENT EVENTS. On October 5, 1995, the Company completed a merger (the
"Enterra Merger") with Enterra Corporation ("Enterra") and changed its name to
"Weatherford Enterra, Inc." Enterra was a worldwide provider of specialized
services and products to the oil and gas industry through its oilfield, pipeline
and compression services and equipment businesses. After giving effect to a
contemporaneous one-for-two reverse stock split, the Company issued
approximately 23,500,000 shares of Common Stock in exchange for all the
outstanding shares of Enterra common stock based on an exchange ratio of 0.845
of a share of Weatherford Common Stock for each share of Enterra common stock
outstanding. The consolidated financial statements contained herein have been
restated for all periods presented to reflect the impact of the reverse stock
split, but not for the Enterra Merger.

    The Enterra Merger will be accounted for as a pooling of interests.
Accordingly, future consolidated financial statements will be restated to
include the accounts and results of operations of Enterra with those of the
Company, as if the two companies had been combined since inception.  See
supplemental condensed consolidated financial statements of Weatherford Enterra,
Inc. contained elsewhere herein.

    In connection with the Enterra Merger, the Company entered into new bank
credit facilities (the "Facilities") consisting of a $200,000,000 term loan (the
"Term Loan") and a $200,000,000 revolving credit facility (the "Revolving Credit
Facility"). The Facilities replaced the primary bank credit facilities that
Weatherford and Enterra previously had in place. The Term Loan is repayable in
23 equal quarterly installments commencing March 31, 1996. The Revolving Credit
Facility matures on September 30, 2000. Amounts outstanding under the Facilities
accrue interest at a variable rate, depending on the Company's total debt-to-
total capitalization ratio. The applicable interest rate on amounts outstanding
at October 31, 1995 was 6.4%. A commitment fee ranging from 0.15% to 0.225% per
annum is payable quarterly on the unused portion of the Revolving Credit
Facility. The Company is required under the Facilities agreement to maintain
certain financial ratios and is limited thereby in its ability to incur
indebtedness, make investments and dispose of assets. The balances outstanding
at October 31, 1995 under the Term Loan and Revolving Credit Facility were
$200,000,000 and $15,000,000, respectively, and the Company had $185,000,000
available to borrow under the Revolving Credit Facility.

    On September 20, 1995, Enterra entered into a definitive agreement with 
Zapata Corporation ("Zapata") to acquire Zapata's natural gas compression 
businesses ("Zapata Energy Industries") for cash of $130,000,000 and the 
assumption of certain liabilities. The Company succeeded to Enterra's rights and
obligations under the Zapata Energy Industries agreement as a result of the 
Enterra Merger. Zapata Energy Industries is engaged in the business of 
fabricating, selling, installing, renting and servicing natural gas compressor 
packages used in the oil and gas industry. The Zapata Energy Industries 
acquisition, which is subject to the approval of Zapata shareholders, is 
expected to close in December 1995. The Company expects to finance this 
acquisition with proceeds from new borrowings under the Revolving Credit 
Facility.

                   WEATHERFORD ENTERRA, INC. AND SUBSIDIARIES
       NOTES TO SUPPLEMENTAL CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

   (1) The supplemental condensed consolidated financial statements represent
the combined results of Weatherford and Enterra on a "pooling of interests"
basis as if the two companies had been combined since inception. No adjustments 
have been made to reflect the pending acquisition of Zapata Energy Industries.

   Certain reclassifications have been made to historical amounts to conform the
financial presentation of the two companies.  Specifically, net proceeds from
involuntary sales of Enterra oilfield equipment totaling $1,734,000 and
$1,296,000 for the three-month periods ended September 30, 1995 and 1994,
respectively, and $4,651,000 and $3,882,000 for the nine-month periods ended
September 30, 1995 and 1994, respectively, have been reclassified from Revenues
to Other (income) expense, net.  In addition, with respect to Weatherford,
depreciation and amortization charges of $10,973,000 and $9,468,000 for the
three-month periods ended September 30, 1995 and 1994, respectively, and
$32,804,000 and $26,180,000 for the nine-month periods ended September 30, 1995
and 1994, respectively, have been reclassified from Cost of sales and services,
Selling, general and administrative expenses and Other (income) expense, net, to
Depreciation and amortization.

   (2) INCOME PER COMMON AND COMMON EQUIVALENT SHARE.  Income per common and
common equivalent share is computed on the basis of the combined weighted
average number of shares of common stock and common stock equivalents of
Weatherford and Enterra for each period presented based upon the conversion rate
of 0.845 of a share of Weatherford Common Stock for each share of Enterra common
stock, after giving effect to a one-for-two reverse stock split of Weatherford
Common Stock.  Fully diluted earnings per share are equal to primary earnings
per share in all periods presented.

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


                                BUSINESS REVIEW

   Weatherford is a diversified international energy service and manufacturing
company that provides a variety of services and equipment to the oil and gas
industry.  Weatherford's principal businesses consist of providing tubular
running services, renting specialized oilfield equipment and providing fishing
services and related tools, and manufacturing and selling cementation products
and other equipment.  Weatherford operates in virtually every oil and gas
exploration and production region in the world.

   Weatherford has grown significantly through acquisition in recent years,
having acquired 21 businesses since November 1991.  As a result of these
acquisitions, the Company is an industry leader in each of its principal
businesses and has expanded its product and service lines, improved its U.S.
market position and realized significant consolidation cost savings.

   On October 5, 1995, the Company completed the Enterra Merger, which
represents Weatherford's most significant business combination to date.  The
Enterra Merger strengthens the Company's position as the worldwide leader in the
rental tools and fishing tool services business and adds gas compression,
pipeline construction services and several manufacturing businesses to the
Company. In connection with the Enterra Merger, the Company effected a one-for-
two reverse stock split and changed its name to "Weatherford Enterra, Inc." The
Company issued approximately 23,500,000 shares of Common Stock in exchange for
all the outstanding shares of Enterra common stock based on an exchange ratio of
0.845 of a share of Weatherford Common Stock (reflecting the reverse stock
split) for each share of Enterra common stock outstanding. The Enterra Merger
will be accounted for as a pooling of interests. Accordingly, future
consolidated financial statements will be restated to include the accounts and
results of operations of Enterra with those of the Company, as if the two
companies had been combined since inception.

   The following table sets forth Weatherford's revenues attributable to each of
its principal businesses (in thousands):

   Demand for the Company's services and products depends primarily upon the
number of oil and gas wells being drilled, the depth and drilling conditions of
such wells, the volume of production, the number of well completions and the
level of workover activity.  Drilling activity is largely dependent on the level
and volatility of oil and natural gas prices.  The following table sets forth

                              FINANCIAL CONDITION

     The Company's operations provided cash of $ 23,651,000 during the first
nine months of 1995 compared to $26,801,000 during the first nine months of
1994.  Net income before depreciation and amortization of $62,177,000 in the
first nine months of 1995 increased $14,773,000 when compared to the same period
in 1994.  Changes in working capital and other operating accounts used cash of
$33,306,000 during the first nine months of 1995 compared to $15,089,000 in the
same period of 1994, primarily as a result of increased payments in 1995 related
to capital assets and inventories purchased in the fourth quarter of 1994 and
increased receivable balances caused by higher revenues.

   Capital expenditures increased to $36,910,000 during the nine months ended
September 30, 1995 compared to $29,103,000 for the same period in 1994.  The
increase was primarily attributable to the international segment, where the
Company expanded its operations during 1994 with acquisitions in the North Sea,
the Asia-Pacific Region and South America.

   The Company's consolidated indebtedness increased slightly from $72,076,000
at December 31, 1994 to $75,912,000  at September 30, 1995.  The Company's total
debt-to-total capitalization ratio improved to 19% at September 30, 1995
compared to 20% at December 31, 1994.

   In connection with the Enterra Merger, the Company entered into new bank
credit facilities consisting of a $200,000,000 Term Loan and a $200,000,000
Revolving Credit Facility.  The Facilities replaced the primary bank credit
facilities that Weatherford and Enterra previously had in place.  The Term Loan
is repayable in 23 equal quarterly installments commencing March 31, 1996.  The
Revolving Credit Facility matures on September 30, 2000.  Amounts outstanding
under the Facilities accrue interest at a variable rate, depending on the
Company's total debt-to-total capitalization ratio.  The applicable interest
rate on amounts outstanding at October 31, 1995 was 6.4%.  A commitment fee
ranging from 0.15% to 0.225% per annum is payable quarterly on the unused
portion of the Revolving Credit Facility. The Company is required under the
Facilities agreement to maintain certain financial ratios and is limited thereby
in its ability to incur indebtedness, make investments and dispose of assets. At
October 31, 1995, the balances outstanding under the Term Loan and the Revolving

                                       13
<PAGE>
 
Credit Facility were $200,000,000 and $15,000,000, respectively, and the Company
had $185,000,000 available to borrow under the Revolving Credit Facility. In
addition, at September 30, 1995, the Company had $9,478,000 available for
borrowing under working capital facilities of certain of its international
subsidiaries.

   On September 20, 1995, Enterra entered into a definitive agreeement with
Zapata to acquire Zapata Energy Industries for cash of $130,000,000 and the
assumption of certain liabilities. The Company succeeded to Enterra's rights and
obligations under the Zapata Energy Industries agreement as a result of the
Enterra Merger. Zapata Energy Industries is engaged in the business of
fabricating, selling, installing, renting and servicing natural gas compressor
packages used in the oil and gas industry. The Zapata Energy Industries
acquisition, which is subject to the approval of Zapata shareholders, is
expected to close in December 1995. The Company expects to finance this
acquisition with proceeds from new borrowings under the Revolving Credit
Facility.

   The Company has entered into forward exchange contracts as a hedge against
certain existing economic exposures.  The market value gains and losses
recognized on the hedges offset foreign currency transaction gains and losses
recognized on the related exposures.  Settlement of forward exchange contracts
resulted in net cash outflows totaling $3,107,000 during the first nine months
of 1995.

   Management believes the combination of working capital, the unused portion of
existing credit facilities and cash flows from operations provide the Company
with sufficient capital resources and liquidity to manage its routine
operations.  The Company continues to seek opportunities to enhance its
competitiveness through strategic acquisitions. Management believes that any
borrowings made in connection with any such acquisitions will not have a
materially adverse impact on the Company's liquidity.

   Like most multinational oilfield service companies, the Company has
operations in certain international areas, including parts of the Middle East,
North and West Africa, Latin America, the Asia-Pacific Region and the
Commonwealth of Independent States (the "CIS"), that are inherently subject to
risks of civil disturbance and political activities that may disrupt oil and
gas exploration and production activities, restrict the movement of funds or
limit access to markets for periods of time.  Historically, the economic impact
of such disruptions has been temporary and oil and gas exploration and
production activities have eventually resumed in relation to market forces.
Certain areas, including the CIS, Algeria and Nigeria, have been subjected to
political disruption or social unrest in the past twelve months.  Generally,
business interruptions resulting from civil or political disruptions negatively
impact near-term results of operations; however, in the opinion of management,
it is unlikely that any specific business disruption caused by existing or
foreseen civil or political instability will have a materially adverse impact on
the financial condition or liquidity of the Company.

   The Company has not declared dividends on Common Stock since December
1982 and management does not anticipate paying dividends on Common Stock at
any time in the foreseeable future.

                             RESULTS OF OPERATIONS

   THIRD QUARTER 1995 COMPARED TO THIRD QUARTER 1994.   Revenues increased 11%
from $94,603,000 in the third quarter of 1994 to $105,119,000 in the third
quarter of 1995, which represented the highest quarterly revenue figure in the
Company's history.  International revenues increased $8,048,000, or 17%, to
$56,625,000 compared to $48,577,000 during the third quarter of 1994, primarily
due to increased service activity in the North Sea, Africa, the Middle East and
Latin America.  During the third quarter of 1995, the average international rig
count (excluding Canada) was 6% higher than in the same period of 1994.  United
States revenues increased $2,468,000, or 5%, to $48,494,000 in the third quarter
of 1995 compared to $46,026,000 for the same period of 1994, primarily as a
result of increased service activity in certain regions.  The average U.S.
drilling rig count was 5% lower in the third quarter of 1995 than in the third
quarter of 1994.

   Gross profit increased $4,267,000, or 17%, to $29,821,000 from $25,554,000
when comparing the third quarter of 1995 to the third quarter of 1994.  As a
percentage of revenues, gross profit improved from 27.0% to 28.4%, primarily
reflecting increased rental activity in the United States and cost savings
achieved in consolidating the operations of H & H Oil Tool Co., Inc. ("H & H")
into Weatherford.  H & H was a U. S. rental and fishing tool company acquired by
merger in September 1994 in a transaction accounted for as a pooling of
interests.  International gross margins were lower in the third quarter of 1995
compared to the third quarter of 1994, primarily as a result of a difference in
the revenue mix geographically and with respect to the services and products
provided, increased costs in certain markets and lower activity levels in the
Asia-Pacific Region.

   Selling, general and administrative expenses were virtually unchanged despite
the increased revenues, decreasing $46,000 to $14,841,000 in the third quarter
of 1995 compared to $14,887,000 in the third quarter of 1994.  As a percentage
of revenues, selling, general and administrative expenses improved from 15.7% to
14.1%, primarily as a result of the revenue growth and cost savings achieved in
consolidating the operations of H & H.

   Research and development costs increased 38% from $748,000 in the third
quarter of 1994 to $1,032,000 in the third quarter of 1995, primarily reflecting
the expansion of the Company's development activities to support its three
principal businesses.

   The Company owns a 49% interest in each of two Saudi Arabian companies and an
Abu Dhabi joint venture.  The Company owned a 50% interest in a U.S. partnership
that was dissolved in 1994.  The Company's equity in the earnings of these
affiliates increased $345,000 to $381,000 in the third quarter of 1995,
primarily as a result of losses incurred by the U.S. partnership during the
third quarter of 1994.

   As a result of the fluctuation of the U.S. dollar against the major foreign
currencies in which the Company conducts business, the Company recorded net
exchange transaction gains of $137,000 in the third quarter of 1995 compared to
net exchange transaction gains of $1,400,000 in the third quarter of 1994.  A
substantial portion of the 1994 gain represented an unrealized currency gain
related to certain intercompany loans.

   Other (income) expense improved from a net expense of $390,000 in the third
quarter of 1994 to income of $393,000 in the same period of 1995, primarily as a
result of increased gains on sales of used rental equipment in the normal course
of business.

                                       15
<PAGE>
 
   The Company recorded acquisition-related costs totaling $2,500,000 in the
third quarter of 1994 related to the H & H merger, primarily representing
transaction fees and employee termination and facility closure costs to
consolidate the H & H operations into Weatherford.

   Operating income increased 76% to $14,859,000 in the third quarter of 1995
compared to $8,465,000 in the same period in 1994, primarily as a result of
higher gross profit in 1995 and the acquisition-related costs in 1994.

   Net interest expense increased by $238,000 to $1,640,000 in the third quarter
of 1995 compared to $1,402,000 in the third quarter of 1994, primarily as a
result of higher market interest rates in 1995.

   The income tax provision consists of taxes on foreign earnings, foreign taxes
withheld on certain remittances from international subsidiaries, U.S.
alternative minimum taxes and U.S. state income taxes.  The income tax provision
does not include U.S. regular federal income tax due to the availability of U.S.
net operating loss carryforwards.  The consolidated income tax provision
increased to $3,342,000 during the third quarter of 1995 compared to $2,064,000
in the third quarter of 1994, primarily reflecting higher pretax earnings. The
Company's overall effective tax rate decreased from 29% to 25%, primarily
reflecting higher earnings in the United States, where net operating loss
carryforwards are available.

   The Company conducts a portion of its business in currencies other than the
U.S. dollar, including the German mark, the U.K. pound sterling, the Norwegian
krone and the Canadian dollar.  As a result of a weaker U.S. dollar, the
weighted average currency exchange rates used to translate the statements of
income of the Company's international subsidiaries were generally lower during
the third quarter of 1995 compared to the same period in 1994, thereby
increasing the amount of U.S. dollars reflected on the Company's 1995
consolidated statements of income.  Had the third quarter 1995 average exchange
rates been the same as in the third quarter of 1994, revenues for the third
quarter of 1995 would have been approximately $1,938,000 lower.  The impact on
net income would not have been material.


   NINE MONTHS 1995 COMPARED TO NINE MONTHS 1994.  Revenues increased 11% from
$275,000,000  in the first nine months of 1994 to $304,206,000 in the first nine
months of 1995.  International revenues increased $24,178,000, or 18%, to
$159,250,000 compared to $135,072,000 during the first nine months of 1994,
primarily as a result of the inclusion of the Odfjell Rental operations acquired
in April 1994, several smaller 1994 acquisitions and increased service activity
in certain markets, including the North Sea, Latin America and Africa.  During
the first nine months of 1995, the average international rig count (excluding
Canada) was 2% higher than during the same period of 1994.  United States
revenues increased 4% to $144,956,000 from $139,928,000 during the first nine
months of 1994, primarily due to a large export sale of products during the
first quarter of 1995 totaling $5,867,000, offset by the impact of lower U.S.
drilling activity.  The average U.S. drilling rig count was 6% lower during the
first nine months of 1995 compared to the same period in 1994.

   Gross profit increased $7,117,000, or 9%, to $84,662,000 from $77,545,000
when comparing the first nine months of 1995 to the same period in 1994.  The
consolidated gross profit percentage decreased from 28.2% to 27.8%, reflecting
differences in the revenue mix geographically and with respect to the services
and products provided and increased costs in certain international markets.

   Selling, general and administrative expenses decreased $772,000, or 2%, to
$43,206,000 in the first nine months of 1995 compared to $43,978,000 in the
first nine months of 1994, primarily as a result of the cost savings achieved in
consolidating the operations of H & H.  As a percentage of revenues, selling,
general and administrative expenses improved from 16.0% to 14.2%, reflecting the
impact of revenue growth and the consolidation cost savings.

                                       16
<PAGE>
 
   Research and development costs increased $671,000, or 31%, to $2,803,000 in
the first nine months of 1995 compared to $2,132,000 in the first nine months of
1994, primarily reflecting the expansion of the Company's development activities
to support its three principal businesses.

   The Company owns a 49% interest in each of two Saudi Arabian companies and an
Abu Dhabi joint venture.  The company owned a 50% interest in a U.S. partnership
that was dissolved in 1994.  The Company's equity in the earnings of these
affiliates increased $473,000, or 59%, to $1,280,000 in the first nine months of
1995, primarily as a result of improved 1995 operating results in Saudi Arabia.

   As a result of the fluctuation of the U.S. dollar against the major foreign
currencies in which the Company conducts business, the Company recorded net
exchange transaction gains of $406,000 in the first nine months of 1995 compared
to net exchange transaction gains of $3,427,000 in the same period in 1994.  A
substantial portion of the 1994 gain represented an unrealized currency gain
related to certain intercompany loans.

   Other (income) expense improved from net expense of $294,000 in the first
nine months of 1994 to income of $2,219,000 in the same period of 1995,
primarily as a result of increased gains on sales of used rental equipment in
the normal course of business.

   The Company recorded acquisition-related costs totaling $2,500,000 in the
third quarter of 1994 related to the H & H merger, primarily representing
transaction fees and employee termination and facility closure costs to
consolidate the H & H operations into Weatherford.

   Operating income increased $9,683,000, or 29%, to $42,558,000 through the
first nine months of 1995 compared to $32,875,000 in the same period in 1994,
primarily as a result of the improved gross profit and other income and the
acquisition-related costs in 1994, partially offset by the large currency gain
in 1994.

   Net interest expense increased by $1,797,000, or 59%, to $4,866,000 in the
first nine months of 1995 compared to $3,069,000 in the first nine months of
1994, primarily as a result of higher average debt balances outstanding in 1995
and higher market interest rates.

   The income tax provision consists of taxes on foreign earnings, foreign taxes
withheld on certain remittances from international subsidiaries, U.S.
alternative minimum taxes and U.S. state income taxes.  The income tax provision
does not include U.S. regular federal income tax due to the availability of U.S.
net operating loss carryforwards.  The consolidated income tax provision
increased to $9,433,000 during the first nine months of 1995 compared to
$7,904,000 in the first nine months of 1994, primarily reflecting higher pretax
earnings.  The Company's overall effective tax rate decreased from 27% for the
first nine months of 1994 to 25% for the first nine months of 1995, primarily 
reflecting higher earnings in the United States where net operating loss 
carryforwards were available.

   The Company conducts a portion of its business in currencies other than the
U.S. dollar, including the German mark, the U.K. pound sterling, the Norwegian
krone and the Canadian dollar.  As a result of a weaker U.S. dollar, the
weighted average currency exchange rates used to translate the statements of
income of the Company's international subsidiaries were generally lower during
the first nine months of 1995 compared to the same period in 1994, thereby
increasing the amount of U.S. dollars reflected on the Company's 1995
consolidated statements of income.  Had the average exchange rates in the first
nine months of 1995 been the same as in the first nine months of 1994, revenues
for the first nine months of 1995 would have been approximately $7,515,000
lower.  The impact on net income would not have been material.

     respectively.

     During the second quarter of 1995, as a result of a review of its operating
strategies and the carrying values of its assets, Enterra recognized unusual 
charges of $28,282,000.  The charge included $10,041,000 related to the 
writedown to expected net realizable values of certain oilfield equipment 
businesses to be disposed and $12,367,000 of writedowns related to rental tools,
properties and certain inventories that were considered excess or obsolete. Also
included in the unusual charges were costs pursuant to formal restructuring 
plans of $4,562,000 related to the closure and associated write-off of assets of
certain pipeline businesses and $1,312,000 to close certain oilfield service 
administrative and operating locations.

     OILFIELD SERVICES AND EQUIPMENT.  Revenues increased 20% from $148,887,000 
in the third quarter of 1994 to $178,011,000 in the third quarter of 1995, 
primarily due to the inclusion of the Total Energy Services ("Total Energy") 
operations, which were acquired by Enterra on August 12, 1994.  For the nine 
months ended September 30, 1995, revenues increased 31% to $515,582,000. 
Compared to the same periods in 1994, U.S. services revenues increased 
$3,013,000, or 5%, in the third quarter of 1995, and $12,358,000, or 8%, for the
nine months ended September 30, 1995, primarily as a result of increased service
activity in certain regions.  International service revenues increased 
$13,497,000, or 27%, in the third quarter of 1995, and $37,303,000, or 26%, for 
the nine months ended September 30, 1995, primarily due to increased drilling 
and service activity in the North Sea, Africa and Latin America.  Oilfield 
equipment revenues increased $12,614,000, or 31%, in the third quarter of 1995, 
and $73,118,000, or 87%, for the nine months ended September 30,1 995, primarily
as a result of the Total energy acquisition in August 1994.

     After considering Enterra's unusual charges in 1995 and Weatherford's 
acquisition-related costs in 1994, operating income in the oilfield services and
equipment segment increased in the three-month and nine-month periods ended 
September 30, 1995 compared to the same periods in 1994, primarily as a result 
of the increased service revenues and cost savings from consolidating the 
operations of H & H and Total Energy.

     PIPELINE SERVICES.  Pipeline services and equipment revenues increased 
$5,079,000, or 36% in the third quarter of 1995 compared to the third quarter of
1994, due to increased worldwide demand for the pipe joint coating services
provided by the Company's U.K.-based operation and continued high demand for
rental of Autoweld equipment, primarily related to the Transmaghreb project in
Algeria. Operating income increased $2,427,000 in the third quarter of 1995
compared to the third quarter of 1994 due to the higher revenues and the effect
of a $1,000,000 charge recognized in the third quarter of 1994 related to the
Allseas project.

     For the nine months ended September 30, 1995, revenues increased 
$13,870,000, or 35%, due to an $8,270,000 increase in the Autoweld division's 
international sales and rentals and a $6,030,000 increase in service revenues by
the Company's pipe joint coating business. Operating income increased to 
$3,385,000 for the 1995 nine-month period as compared to a loss of $222,000 in 
the same period in 1994. Exclusive of the restructuring and asset impairment 
charges in the second quarter of 1995, and the Allseas charges recorded in the 
second and third quarters of 1994, operating income was $7,947,000 in the 1995 
period versus $1,778,000 in 1994. The increase is attributable to the increased 
revenues, especially those associated with the higher margin Autoweld revenues.

     GAS COMPRESSION.  The gas compression segment was acquired as part of the 
Total Energy acquisition in August 1994. Revenues from compressor rentals have 
remained constant at approximately $9,000,000 per quarter since the acquisition 
of this segment.  Operating comparisons to specific periods ended September 30, 
1994 are not meaningful due to the short period of ownership in 1994. While both
the average rental rate and average utilization have fallen slightly
since August 1994, additional higher horsepower units have been added to the
compressor fleet to offset the decline. This segment has experienced a
substantial decline in compressor sales in the third quarter of 1995, as many
customers have deferred the acquisition of units due to the relatively low
demand for natural gas. No significant improvement in compressor sales is
expected for the balance of 1995.

                                  THE CREDITS

     2.01 Amounts and Terms of Commitments.

          (a) The Term Loan Facility.  Each Bank severally agrees, on the terms
and conditions set forth herein, to make loans to the Term Loan Borrower (each
such loan, a "Term Loan") from time to time on any Business Day during the
period from the Closing Date to the Term Loan Commitment Termination Date, in an
aggregate amount not to exceed such Bank's Pro Rata Share of the Term Loan
Commitment.  Amounts borrowed as Term Loans which are repaid or prepaid by the
Term Loan Borrower may not be reborrowed.

          (b) The Revolving Credit Facility.  Each Bank severally agrees
further, on the terms and conditions set forth herein, to make loans to one or
more of the Revolving Loan Borrowers (each such loan, a "Revolving Loan") from
time to time on any Business Day during the period from the Closing Date to the
Revolving Credit Termination Date, in an aggregate amount not to exceed at any
time outstanding such Bank's Pro Rata Share of the Revolving Credit Commitment
(such amount, together with the Bank's Pro Rata Share of the Term Loan
Commitment, as the same may be reduced under Section 2.05 or Section 2.07 or
modified as a result of one or more assignments under Section 10.08, the Bank's
"Commitment").  Within the limits of each Bank's Commitment, and subject to the
other terms and conditions hereof, the Revolving Loan Borrowers may borrow under
this subsection 2.01(b), prepay under Section 2.06 and Section 2.07 and reborrow
under this subsection 2.01(b).

          (c) The initial Pro Rata Share and initial Commitment of each of the
Banks signatories hereto are set forth on Schedule 2.01 attached hereto.

     2.02 Certain Pricing Terms.

          (a) Pricing Based on Capitalization Ratio.  The Applicable Margins and
the Commitment Fee shall be equal to the specified percent per annum set forth
in Schedule 2.02, in each case based upon the Capitalization Ratio as measured
at the end of the preceding fiscal quarter of the Company.

                                       17
<PAGE>
 
          (b) Procedure for Adjustments.  During the period from the Closing
Date through and including the first date on which financial statements and the
related Compliance Certificate are delivered pursuant to Sections 6.01(a) and
6.02 hereof, for purposes of the pricing chart set forth in Schedule 2.02, the
Capitalization Ratio shall be assumed to be an amount classified as "Level III"
therein.  Thereafter, the Applicable Margins(s) and the Commitment Fee shall be
calculated in reliance on the most recent financial statements and Compliance
Certificate delivered pursuant to Sections 6.01 and 6.02 hereof.  Each
adjustment of the Applicable Margin and the Commitment Fee shall be made by the
Administrative Agent as of the first day following the date of delivery of the
financial statements and Compliance Certificate pursuant to Sections 6.01 and
6.02 (the "Adjustment Date").  Such adjusted Applicable Margin and Commitment
Fee shall be effective as of the Adjustment Date, except that with respect to
all Eurodollar Loans outstanding on the Adjustment Date, the adjusted Applicable
Margin shall apply as of the first day of the Interest Period next following the
Adjustment Date.  Notwithstanding the foregoing, in the event the Company shall
fail for any reason to deliver any of the requisite financial statements or
related Compliance Certificate by the applicable date specified in Sections 6.01
and 6.02, the Applicable Margin and Commitment Fee shall be determined, from the
first day after the date such financial statements and Compliance Certificate
were required to have been delivered pursuant to Sections 6.01 and 6.02 (without
regard to any grace or cure period applicable thereto pursuant to Article 8
hereof) until the same are delivered in accordance therewith, on the assumption
that the Capitalization Ratio is an amount classified in Schedule 2.02 as "Level
IV."

     2.03 Procedure for Borrowing.

          (a) Each Borrowing of Revolving Loans or Term Loans shall be made upon
the applicable Borrower's irrevocable written notice delivered to the
Administrative Agent in the form of a Notice of Borrowing (which notice must be
received by the Administrative Agent prior to 9:00 a.m. (Houston, Texas time)
(i) three (3) Business Days prior to the requested Borrowing Date, in the case
of Eurodollar Rate Loans, and (ii) one (1) Business Day prior to the requested
Borrowing Date, in the case of Base Rate Loans), specifying:

          (A)  the amount of the Borrowing, which shall be in an aggregate
     minimum amount of $5,000,000 or any multiple of $1,000,000 in excess
     thereof;

          (B) the applicable Borrower or Borrowers;

          (C) the requested Borrowing Date, which shall be a Business Day;

          (D) the Interest Rate Type of Loans comprising the Borrowing, and
     whether such Loans are to be Term Loans or Revolving Loans; and

          (E) in the case of Eurodollar Rate Loans, the duration of the Interest
     Period applicable to such Loans included in such notice.  If the Notice of
     Borrowing fails to specify the duration of the Interest Period for any

                                       18
<PAGE>
 
     Borrowing comprised of Eurodollar Rate Loans, such Interest Period shall be
     three months.

          (b) The Administrative Agent will promptly notify each Bank of its
receipt of any Notice of Borrowing and of the amount of such Bank's Pro Rata
Share of that Borrowing.

          (c) Each Bank will make the amount of its Pro Rata Share of each
Borrowing available to the Administrative Agent for the account of the
applicable Borrower(s) at the Administrative Agent's Payment Office by 11:00
a.m. (Houston, Texas time) on the Borrowing Date requested by the applicable
Borrower(s) in funds immediately available to the Administrative Agent.  The
proceeds of all such Loans will then be made available to the applicable
Borrower(s) by the Administrative Agent at such office by crediting the account
of the applicable Borrower(s) on the books of the Administrative Agent with the
aggregate of the amounts made available to the Administrative Agent by the Banks
and in  like funds as received by the Administrative Agent.

          (d) After giving effect to any Borrowing, there may not be more than
eight (8) different Interest Periods in effect.

     2.04 Conversion and Continuation Elections.

          (a) The Borrowers may, upon irrevocable written notice to the
Administrative Agent in accordance with subsection 2.04(b):  (i)  elect, as of
any Business Day, in the case of Base Rate Loans, or as of the last day of the
applicable Interest Period, in the case of Eurodollar Rate Loans, to convert any
such Loans (or any part thereof in an amount not less than $5,000,000, or that
is in an integral multiple of $1,000,000 in excess thereof) into Loans of any
other Interest Rate Type; or (ii) elect as of the last day of the applicable
Interest Period, to continue as Eurodollar Rate Loans any Revolving Loans or
Term Loans having Interest Periods expiring on such day (or any part thereof in
an amount not less than $5,000,000, or that is in an integral multiple of
$1,000,000 in excess thereof); provided, that if at any time the aggregate
amount of Eurodollar Rate Loans in respect of any Borrowing is reduced, by
payment, prepayment, or conversion of part thereof to be less than $1,000,000,
such Eurodollar Rate Loans shall automatically convert into Base Rate Loans, and
on and after such date the right of the applicable Borrowers to continue such
Loans as, and convert such Loans into, Eurodollar Rate Loans shall terminate.

          (b) The applicable Borrowers shall deliver a Notice of Conversion/
Continuation to be received by the Administrative Agent not later than 9:00 a.m.
(Houston, Texas time) at least (i) three (3) Business Days in advance of the
Conversion/Continuation Date, if the Loans are to be converted into or continued
as Eurodollar Rate Loans; and (ii) one (1) Business Day in advance of the
Conversion/Continuation Date, if the Loans are to be converted into Base Rate
Loans, specifying:  (A) the proposed Conversion/Continuation Date; (B) the
identity of the applicable Borrower or Borrowers, the Interest Rate Type of
Loans to be converted or continued and whether such Loans are Revolving Loans or
Term Loans; (C) the aggregate amount of Loans to be converted or continued; (D)
the Interest Rate Type of Loans resulting from the proposed conversion or
continuation; and (E) other than in the case of conversions into Base Rate
Loans, the duration of the requested Interest

                                       19
<PAGE>
 
Period(s).  If the Notice of Conversion/Continuation fails to specify the
duration of the Interest Period for any Borrowing comprised of Eurodollar Rate
Loans, such Interest Period shall be three (3) months.

          (c) If upon the expiration of any Interest Period applicable to
Eurodollar Rate Loans, the Company has failed to select timely a new Interest
Period to be applicable to such Eurodollar Rate Loans, or if any Default or
Event of Default then exists, the applicable Borrowers shall be deemed to have
elected to convert such Eurodollar Rate Loans into Base Rate Loans effective as
of the expiration date of such Interest Period.

          (d) The Administrative Agent will promptly notify each Bank of its
receipt of a Notice of Conversion/Continuation, or, if no timely notice is
provided by the applicable Borrowers, the Administrative Agent will promptly
notify each Bank of the details of any automatic conversion.  All conversions
and continuations shall be made ratably according to the respective outstanding
principal amounts of the Loans with respect to which the notice was given held
by each Bank.

          (e) Unless the Majority Banks otherwise agree, during the existence of
a Default or Event of Default, the applicable Borrowers may not elect to have a
Loan converted into or continued as a Eurodollar Rate Loan.

          (f) After giving effect to any conversion or continuation of Loans,
there may not be more than eight (8) different Interest Periods in effect.

     2.05 Voluntary Termination or Reduction of Commitments.  The Company may,
upon not less than five (5) Business Days' prior notice to the Administrative
Agent, terminate the Commitments, or permanently reduce the Commitments by an
aggregate minimum amount of $5,000,000 or any multiple of $1,000,000 in excess
thereof; unless, after giving effect thereto and to any prepayments of Loans
made on the effective date thereof, the Effective Amount of all Revolving Loans
and Term Loans together would exceed the amount of the combined Commitments then
in effect.  Once reduced in accordance with this Section, the Commitments may
not be increased.  Any reduction of the Commitments shall be applied to each
Bank according to its Pro Rata Share.  All accrued Commitment Fees to, but not
including, the effective date of any reduction or termination of Commitments,
shall be paid on the effective date of such reduction or termination.  In the
event of any optional prepayment of Term Loans pursuant to Section 2.06 of this
Agreement, or any mandatory prepayment of Term Loans pursuant to Section 2.07 of
this Agreement, the Term Loan Commitment (and, correspondingly, the total
Commitments) automatically shall reduce by the amount of such prepayment.

     2.06 Optional Prepayments.  Subject to Section 3.04, the Borrowers may, at
any time or from time to time, upon not less than three (3) Business Days'
irrevocable notice to the Administrative Agent, prepay Base Rate Loans and/or
Eurodollar Rate Loans in whole or in part, in each such case in minimum amounts
of $5,000,000 or any multiple of $1,000,000 in excess thereof.  Such notice of
prepayment shall specify the date and amount of each such prepayment, the
Interest Rate Type(s) of the Loans to be prepaid, the identity of the applicable
Borrower or Borrowers and whether such Loans are Revolving Loans or Term Loans.
The Administrative Agent will promptly notify each Bank of its receipt of any

                                       20
<PAGE>
 
such notice, and of such Bank's Pro Rata Share of such prepayment.  If such
notice is given by the applicable Borrower(s), the applicable Borrower(s) shall
make such prepayment and the payment amount specified in such notice shall be
due and payable on the date specified therein, together with accrued interest to
each such date on the amount prepaid and any amounts required pursuant to
Section 3.04.  Optional prepayments of the Term Loans shall be applied to the
then remaining installments payable in respect of the Term Loans on a pro rata
basis (based upon the scheduled principal amount of each such installment after
giving effect to all prior reductions thereto).

     2.07 Mandatory Prepayments; Mandatory Commitment Reductions.

          (a)  If the Company or any of its Consolidated Subsidiaries issues
capital stock or other equity interests for cash proceeds after the Closing Date
(other than capital stock issued pursuant to the Company's employee or director
stock based plans), 100% of the Net Proceeds of such issuance shall be applied
in prepayment of the outstanding Loans, such amount to be applied 50% to the
outstanding Term Loans and 50% to the outstanding Revolving Loans.  Such
prepayment shall be made on or before that date which is ten (10) days after the
date of such issuance.

          (b) In addition to the foregoing, if the Company for any reason does
not consummate the EI Acquisition on or before the Term Loan Commitment
Termination Date, (i) the Revolving Credit Commitment of the Banks hereunder
automatically shall reduce by the amount of $65,000,000 (such that, for example,
absent any other reduction therein, the amount thereof would reduce
automatically to $135,000,000), (ii) the Term Loan Commitment of the Banks
hereunder automatically shall reduce by the amount of $65,000,000, (iii) the
Revolving Loan Borrowers shall prepay the Revolving Loans by an amount
sufficient to reduce the aggregate principal amount of indebtedness and
liabilities of the Revolving Loan Borrowers under the Revolving Notes to an
amount that is less than or equal to the then Revolving Credit Commitment (after
giving effect to the reduction thereof pursuant to this subsection 2.07(b)), and
(iv) the Term Loan Borrower shall prepay the Term Loans by an amount sufficient
to reduce the aggregate principal amount of indebtedness and liabilities of the
Term Loan Borrower under the Term Notes to an amount that is less than or equal
to the then Term Loan Commitment (after giving effect to the reduction thereof
pursuant to this subsection 2.07(b)).

          (c)  Any prepayment of the Term Loans pursuant to this Section 2.07
shall be applied pro rata to the then remaining installments payable in respect
of the Term Loans, and shall be applied, unless otherwise directed by the Term
Loan Borrower to the Administrative Agent in writing, first to any Base Rate
Loans then outstanding and then, to the extent available, to the Eurodollar
Loans then outstanding with the shortest Interest Periods remaining, and, in the
event of any such prepayment of the Term Loans, the Term Loan Commitment (and,
correspondingly, the total Commitments) automatically shall reduce by the amount
of such prepayment.

          (d)  Any prepayment of the Revolving Loans pursuant to this Section
2.07 shall be applied first to any Base Rate Loans then outstanding and then, to
the extent available, to any Eurodollar Rate Loans then outstanding with the
shortest Interest Periods remaining; provided, however, that, except as provided
in subsection (b) of this Section 2.07,

                                       21
<PAGE>
 
such prepayment shall not have the effect of reducing the Revolving Credit
Commitment of the Banks hereunder.

          (e)  The Borrowers shall pay, together with each prepayment under this
Section 2.07, accrued interest on the amount prepaid and any amounts required
pursuant to Section 3.04.

     2.08 Repayment.

          (a) The Term Credit.  The Term Loan Borrower shall repay the Term
Loans in twenty-three (23) installments, all of such installments, except for
the last, being in the amount, rounded to the nearest one-hundredth of a dollar,
equal to one twenty-third (1/23) of the aggregate principal balance of the Term
Loans outstanding on January 1, 1996, and the last and final installment being
in the amount of the then remaining unpaid principal balance thereof, the first
such installment of principal being due and payable on March 31, 1996, and a
subsequent installment of principal being due and payable on the last day of
each succeeding calendar quarter thereafter until the Term Loan Maturity Date,
when the then remaining unpaid balance of principal of the Term Loans, and all
accrued unpaid interest in respect thereof, shall be due and payable in full.

          (b) The Revolving Credit.  The Revolving Loan Borrowers shall repay to
the Banks on the Revolving Credit Termination Date the aggregate principal
amount of Revolving Loans outstanding on such date.

          (c)      Interest.

               (i) Each Revolving Loan and each Term Loan shall bear interest on
     the outstanding principal amount thereof from the applicable Borrowing Date
     at a rate per annum equal to the Eurodollar Rate or the Base Rate, as the
     case may be (and subject to the Borrowers' right to convert to other
     Interest Rate Types of Loans under Section 2.04), plus the Applicable
     Margin.

               (ii) Interest on each Revolving Loan and Term Loan shall be paid
     in arrears on each Interest Payment Date.  Interest shall also be paid on
     the date of any prepayment of Loans under Section 2.06 or 2.07 for the
     portion of the Loans so prepaid and upon payment (including prepayment) in
     full thereof and, during the existence of any Event of Default, interest
     shall be paid on demand of the Administrative Agent at the request or with
     the consent of the Majority Banks.

               (iii)  Notwithstanding subsection (i) of this subsection 2.08(c),
     while any Event of Default exists or after acceleration, the Borrowers
     shall pay interest (after as well as before entry of judgment thereon to
     the extent permitted by law) on the principal amount of all outstanding
     Obligations, at a rate per annum equal to the Base Rate plus two percent
     (2%).

                                       22
<PAGE>
 
          (d) Anything herein to the contrary notwithstanding, the obligations
of the Borrowers to any Bank hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder, to the extent (but only to the extent) that contracting for,
collecting, charging, taking, reserving or receiving such payment by such Bank
would be contrary to the provisions of any law applicable to such Bank limiting
the highest rate of interest that may be lawfully contracted for, collected,
charged, taken, reserved or received by such Bank, and in such event the
Borrowers shall pay such Bank interest as provided in Section 10.16.

     2.09 Fees.

          (a) Arrangement, Agency and Participation Fees.  The Company shall (i)
pay an arrangement fee to the Arrangers for the Arrangers' own accounts, as
required by the fee letter (the "Fee Letter") among the Agents, the Arrangers
and Weatherford, dated August 28, 1995, (ii) pay an agency fee to the
Administrative Agent for the Administrative Agent's own account, as required by
the letter agreement (the "Administrative Agent's Letter") between Weatherford
and the Administrative Agent dated August 28, 1995, and (iii) pay participation
fees to the Administrative Agent, for the account of each of the Banks, as
provided in the invitation letters (the "Invitation Letters") from Weatherford
to the respective Banks.

          (b) Commitment Fees.  The Company also shall pay to the Administrative
Agent for the account of each Bank a fee (the "Commitment Fee") on the average
daily unused portion of such Bank's Commitment, computed on a quarterly basis in
arrears on the last Business Day of each calendar quarter based upon the daily
utilization for that quarter as calculated by the Administrative Agent, equal to
the applicable percent per annum denominated "Commitment Fee," determined from
time to time with reference to the relevant Capitalization Ratio, as set forth
on Schedule 2.02 attached hereto.  For purposes of calculating utilization under
this subsection, the Commitments shall be deemed used to the extent of the
Effective Amount of Revolving Loans and Term Loans then outstanding.  Such
commitment fee shall accrue from the Closing Date to the Revolving Credit
Termination Date and shall be due and payable quarterly in arrears on the last
Business Day of each calendar quarter commencing on December 31, 1995, with the
final payment to be made on the Revolving Credit Termination Date; provided
that, in connection with any reduction or termination of Commitments under
Section 2.05 or Section 2.07, the accrued Commitment Fee calculated for the
period ending on such date shall also be paid on the date of such reduction or
termination, with the following quarterly payment being calculated on the basis
of the period from such reduction or termination date to such quarterly payment
date.  The Commitment Fee provided in this subsection shall accrue at all times
from and after the date of this Agreement.

<PAGE>
 
     2.10 Computation of Fees and Interest.

          (a) All computations of interest for Base Rate Loans shall be made on
the basis of a year of 365 or 366 days, as the case may be, and actual days
elapsed.  All other computations of fees and interest shall be made on the basis
of a 360-day year and actual days elapsed (which results in more interest being
paid than if computed on the basis of a 365-day year).  Interest and fees shall
accrue during each period during which interest or such fees are computed from
the first day thereof to the last day thereof.

          (b) Each determination of an interest rate by the Administrative Agent
shall be conclusive and binding on the Company, the Borrowers and the Banks in
the absence of manifest error.  The Administrative Agent will, at the request of
the Company, the Borrowers or any Bank, deliver to the Company, the Borrowers or
the Bank, as the case may be, a statement showing the quotations used by the
Administrative Agent in determining any interest rate and the resulting interest
rate.

     2.11 Payments by the Company and/or the Borrowers.

          (a) All payments to be made by the Company and/or the Borrowers shall
be made without set-off, recoupment or counterclaim.  Except as otherwise
expressly provided herein, all payments by the Company and/or the Borrowers
shall be made to the Administrative Agent for the account of the Banks at the
Administrative Agent's Payment Office, and shall be made in dollars and in
immediately available funds, no later than 10:00 a.m. (Houston, Texas time) on
the date specified herein.  The Administrative Agent will promptly distribute to
each Bank its Pro Rata Share (or other applicable share as expressly provided
herein) of such payment in like funds as received.  Any payment received by the
Administrative Agent later than 10:00 a.m. (Houston, Texas time) shall be deemed
to have been received on the following Business Day and any applicable interest
or fee shall continue to accrue.

          (b) Subject to the provisions set forth in the definition of "Interest
Period" herein, whenever any payment is due on a day other than a Business Day,
such payment shall be made on the following Business Day, and such extension of
time shall in such case be included in the computation of interest or fees, as
the case may be.

          (c) Unless the Administrative Agent receives notice from the Company
and/or the Borrowers prior to the date on which any payment is due to the Banks
that the Company and/or the Borrowers will not make such payment in full as and
when required, the Administrative Agent may assume that the Company and/or the
Borrowers have made such payment in full to the Administrative Agent on such
date in immediately available funds and the Administrative Agent may (but shall
not be so required), in reliance upon such assumption, distribute to each Bank
on such due date an amount equal to the amount then due such Bank.  If and to
the extent the Company and/or the Borrowers have not made such payment in full
to the Administrative Agent, each Bank shall repay to the Administrative Agent
on demand such amount distributed to such Bank, together with interest thereon
at the Federal Funds Rate for each day from the date such amount is distributed
to such Bank until the date repaid.

     2.12 Payments by the Banks to the Administrative Agent.

          (a) Unless the Administrative Agent receives notice from a Bank on or
prior to the Closing Date or, with respect to any Borrowing after the Closing
Date, at least one Business Day prior to the date of such Borrowing, that such
Bank will not make available as and when required hereunder to the
Administrative Agent for the account of the Borrowers the amount of that Bank's
Pro Rata Share of the Borrowing, the Administrative Agent may assume that each
Bank has made such amount available to the Administrative Agent in immediately
available funds on the Borrowing Date and the Administrative Agent may (but
shall not be so required), in reliance upon such assumption, make available to
the Borrowers on such date a corresponding amount.  If and to the extent any
Bank shall not have made its full amount available to the Administrative Agent
in immediately available funds and the Administrative Agent in such
circumstances has made available to the Borrowers such amount, that Bank shall
on the Business Day following such Borrowing Date make such amount available to
the Administrative Agent, together with interest at the Federal Funds Rate for
each day during such period.  A notice of the Administrative Agent submitted to
any Bank with respect to amounts owing under this subsection (a) shall be
conclusive, absent manifest error.  If such amount is so made available, such
payment to the Administrative Agent shall constitute such Bank's Loan on the
date of Borrowing for all purposes of this Agreement.  If such amount is not
made available to the Administrative Agent on the Business Day following the
Borrowing Date, the Administrative Agent will notify the Borrowers of such
failure to fund and, upon demand by the Administrative Agent, the Borrowers
shall pay such amount to the Administrative Agent for the Administrative Agent's
account, together with interest thereon for each day elapsed since the date of
such Borrowing, at a rate per annum equal to the interest rate applicable at the
time to the Loans comprising such Borrowing.

          (b) The failure of any Bank to make any Loan on any Borrowing Date
shall not relieve any other Bank of any obligation hereunder to make a Loan on
such Borrowing Date, but no Bank shall be responsible for the failure of any
other Bank to make the Loan to be made by such other Bank on any Borrowing Date.

     2.13 Sharing of Payments, Etc.  If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its Pro Rata Share, such Bank shall
immediately (a) notify the Administrative Agent of such fact, and (b) purchase
from the other Banks such participations in the Loans made by them as shall be
necessary to cause such purchasing Bank to share the excess payment pro rata
with each of them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from the purchasing Bank, such purchase shall to
that extent be rescinded and each other Bank shall repay to the purchasing Bank
the purchase price paid therefor, together with an amount equal to such paying
Bank's ratable share (according to the proportion of (i) the amount of such
paying Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered.  The Company and
the Borrowers agree that any Bank so purchasing a participation from another
Bank may, to the fullest extent permitted by law, exercise all its rights of
payment (including the right of set-off, but subject to Section 10.09) with
respect to such participation as fully as if

                                       25
<PAGE>
 
such Bank were the direct creditor of the Company and/or the Borrowers in the
amount of such participation.  The Administrative Agent will keep records (which
shall be conclusive and binding in the absence of manifest error) of
participations purchased under this Section and will in each case notify the
Banks following any such purchases or repayments.


                                  ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01 Taxes.

          (a) Any and all payments by the Company and/or the Borrowers to the
Banks or the Agents under this Agreement and any other Loan Document shall be
made free and clear of, and without deduction or withholding for, any Taxes.  In
addition, the Company and/or the Borrowers shall pay all Other Taxes.

          (b) The Company and each of the Borrowers agrees to indemnify and hold
harmless each Bank and the Administrative Agent for the full amount of Taxes or
Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on
amounts payable under this Section) paid by the Bank or the Administrative Agent
and any liability (including penalties, interest, additions to tax and expenses)
arising therefrom or with respect thereto, whether or not such Taxes or Other
Taxes were correctly or legally asserted.  Payment under this indemnification
shall be made within 30 days after the date the Bank or the Administrative Agent
makes written demand therefor, accompanied by the certificate described in
Section 3.07 of this Agreement.

          (c) If the Company and/or the Borrowers shall be required by law to
deduct or withhold any Taxes or Other Taxes from or in respect of any sum
payable hereunder to any Bank or the Administrative Agent, then:

               (i) the sum payable shall be increased as necessary so that after
     making all required deductions and withholdings (including deductions and
     withholdings applicable to additional sums payable under this Section) such
     Bank or the Administrative Agent, as the case may be, receives an amount
     equal to the sum it would have received had no such deductions or
     withholdings been made;

               (ii) the Company and/or the Borrowers, as applicable, shall make
     such deductions and withholdings;

               (iii)  the Company and/or the Borrowers, as applicable, shall pay
     the full amount deducted or withheld to the relevant taxing authority or
     other authority in accordance with applicable law; and

               (iv) the Company and/or the Borrowers, as applicable, shall also
     pay to each Bank or the Administrative Agent for the account of such Bank,
     at the time interest is paid, all additional amounts which the respective

                                       26
<PAGE>
 
     Bank specifies as necessary to preserve the after-tax yield the Bank would
     have received if such Taxes or Other Taxes had not been imposed.

          (d) Within 30 days after the date of any payment by the Company and,
or, the Borrowers, as applicable, of Taxes or Other Taxes, the Company and/or
the Borrowers, as applicable, shall furnish the Administrative Agent the
original or a certified copy of a receipt evidencing payment thereof, or other
evidence of payment reasonably satisfactory to the Administrative Agent.

          (e) If the Company and/or the Borrowers, as applicable, is required to
pay additional amounts to any Bank or the Administrative Agent pursuant to
subsection (c) of this Section, then such Bank shall use reasonable efforts
(consistent with legal and regulatory restrictions) to change the jurisdiction
of its Lending Office so as to eliminate any such additional payment by the
Company and/or the Borrowers, as applicable, which may thereafter accrue, if
such change in the judgment of such Bank is not otherwise disadvantageous to
such Bank.

     3.02 Illegality.

          (a) If any Bank determines that the introduction of any Requirement of
Law, or any change in any Requirement of Law, or in the interpretation or
administration of any Requirement of Law, has made it unlawful, or that any
central bank or other Governmental Authority has asserted that it is unlawful,
for any Bank or its applicable Lending Office to make Eurodollar Rate Loans,
then, on notice thereof by the Bank to the Company through the Administrative
Agent, any obligation of that Bank to make Eurodollar Rate Loans shall be
suspended until the Bank notifies the Administrative Agent and the Company that
the circumstances giving rise to such determination no longer exist.

          (b) If a Bank determines that it is unlawful to maintain any
Eurodollar Rate Loan, the applicable Borrower(s) shall, upon receipt of notice
of such fact and demand from such Bank (with a copy to the Administrative
Agent), prepay in full such Eurodollar Rate Loans of that Bank then outstanding,
together with interest accrued thereon and amounts required under Section 3.04,
either on the last day of the Interest Period thereof, if the Bank may lawfully
continue to maintain such Eurodollar Rate Loans to such day, or immediately, if
the Bank may not lawfully continue to maintain such Eurodollar Rate Loan.  If a
Borrower is required to so prepay any Eurodollar Rate Loan, then concurrently
with such prepayment (unless the Borrower simultaneously prepays the
corresponding Eurodollar Rate Loans of every other Bank), such Borrower shall
borrow from the affected Bank, in the amount of such repayment, a Base Rate
Loan.

          (c) If the obligation of any Bank to make or maintain Eurodollar Rate
Loans has been so terminated or suspended, all Loans which would otherwise be
made by the Bank as Eurodollar Rate Loans shall be instead Base Rate Loans.

          (d) Before giving any notice to the Administrative Agent under this
Section, the affected Bank shall designate a different Lending Office with
respect to its Eurodollar Rate Loans if such designation will avoid the need for
giving such notice or making such

                                       27
<PAGE>
 
demand and will not, in the judgment of the Bank, be illegal or otherwise
disadvantageous to the Bank.

     3.03 Increased Costs and Reduction of Return.

          (a) If any Bank determines that, due to either (i) the introduction of
or any change in or in the interpretation of any law or regulation or (ii) the
compliance by that Bank with any guideline or request from any central bank or
other Governmental Authority (whether or not having the force of law), there
shall be any increase in the cost to such Bank of agreeing to make or making,
funding or maintaining any Eurodollar Rate Loans, then the Company and the
Borrowers shall be liable for, and shall from time to time, upon written demand,
accompanied by the certificate described in Section 3.07 of this Agreement (with
a copy of such demand and certificate to be sent to the Administrative Agent),
pay to the Administrative Agent for the account of such Bank, additional amounts
as are sufficient to compensate such Bank for such increased costs.

          (b) If any Bank shall have determined that (i) the introduction of any
Capital Adequacy Regulation, (ii) any change in any Capital Adequacy Regulation,
(iii) any change in the interpretation or administration of any Capital Adequacy
Regulation by any central bank or other Governmental Authority charged with the
interpretation or administration thereof, or (iv) compliance by the Bank (or its
Lending Office) or any corporation controlling the Bank with any Capital
Adequacy Regulation, affects or would affect the amount of capital required or
expected to be maintained by the Bank or any corporation controlling the Bank
and (taking into consideration such Bank's or such corporation's policies with
respect to capital adequacy and such Bank's desired return on capital)
determines that the amount of such capital is increased as a consequence of its
Commitments, loans, credits or obligations under this Agreement, then, upon
written demand of such Bank to the Company, accompanied by the certificate
described in Section 3.07 of this Agreement (with a copy of such demand and
certificate to be sent to the Administrative Agent), the Company and/or the
Borrowers, as applicable, shall pay to the Bank, from time to time as specified
by the Bank, additional amounts sufficient to compensate the Bank for such
increase.

     3.04 Funding Losses.  The Company and the Borrowers shall reimburse each
Bank and hold each Bank harmless from any loss or expense which the Bank may
sustain or incur as a consequence of:

          (a) the failure of the Borrowers to make on a timely basis any payment
of principal of any Eurodollar Rate Loan;

          (b) the failure of the Borrowers to borrow, continue or convert a Loan
after the Company has given (or is deemed to have given) a Notice of Borrowing
or a Notice of Conversion/Continuation;

          (c) the failure of the Borrowers to make any prepayment in accordance
with any notice delivered under Section 2.06;

                                       28
<PAGE>
 
          (d) the prepayment (including pursuant to Section 2.06 or Section
2.07) or other payment (including after acceleration thereof) of a Eurodollar
Rate Loan on a day that is not the last day of the relevant Interest Period; or

          (e) the automatic conversion under Section 2.04 of any Eurodollar Rate
Loan to a Base Rate Loan on a day that is not the last day of the relevant
Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Eurodollar Rate Loans or from fees
payable to terminate the deposits from which such funds were obtained.  For
purposes of calculating amounts payable by the Company and/or the Borrowers to
the Banks under this Section and under subsection 3.03(a), each Eurodollar Rate
Loan made by a Bank (and each related reserve, special deposit or similar
requirement) shall be conclusively deemed to have been funded at the reference
rate used in determining the Eurodollar Rate for such Eurodollar Rate Loan by a
matching deposit or other borrowing in the interbank eurodollar market for a
comparable amount and for a comparable period, whether or not such Eurodollar
Rate Loan is in fact so funded.

     3.05 Inability to Determine Rates.  If the Administrative Agent determines
that for any reason adequate and reasonable means do not exist for determining
the Eurodollar Rate for any requested Interest Period with respect to a proposed
Eurodollar Rate Loan, or that the Eurodollar Rate applicable for any requested
Interest Period with respect to a proposed Eurodollar Rate Loan does not
adequately and fairly reflect the cost to the Banks of funding such Loan, the
Administrative Agent will promptly so notify the Company and each Bank.
Thereafter, the obligation of the Banks to make or maintain Eurodollar Rate
Loans hereunder shall be suspended until the Administrative Agent upon the
instruction of the Majority Banks revokes such notice in writing.  Upon receipt
of such notice, the Company may revoke any Notice of Borrowing or Notice of
Conversion/Continuation then submitted by it.  If the Company does not revoke
such notice, the Banks shall make, convert or continue the Loans, as proposed by
the Company, in the amount specified in the applicable notice submitted by the
Company, but such Loans shall be made, converted or continued as Base Rate Loans
instead of Eurodollar Rate Loans.

     3.06 Reserves on Eurodollar Rate Loans.  The Company and/or the Borrowers
shall pay to each Bank, as long as such Bank shall be required under regulations
of the FRB to maintain reserves with respect to liabilities or assets consisting
of or including Eurocurrency funds or deposits (currently known as "Eurocurrency
liabilities"), additional costs on the unpaid principal amount of each
Eurodollar Rate Loan equal to the actual costs of such reserves allocated to
such Loan by the Bank (as determined by the Bank in good faith, which
determination shall be conclusive absent manifest error), payable on each date
on which interest is payable on such Loan, provided the Company shall have
received at least 15 days' prior written notice (with a copy to the
Administrative Agent) of such additional interest from the Bank.  If a Bank
fails to give notice 15 days prior to the relevant Interest Payment Date, such
additional interest shall be payable 15 days from receipt of such notice.  Any
such notice shall be accompanied by the certificate described in Section 3.07 of
this Agreement.

                                       29
<PAGE>
 
     3.07 Certificates of Banks.  Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the Company (with a copy to
the Administrative Agent) a certificate setting forth in reasonable detail the
amount payable to the Bank hereunder and such certificate shall be conclusive
and binding on the Company and the Borrowers in the absence of manifest error.
All determinations by a Bank of a right to reimbursement or compensation under
this Article III shall be made in good faith and on a reasonable basis.

     3.08 Substitution of Banks.  Upon the receipt by the Company from any Bank
(an "Affected Bank") of a claim for compensation under Section 3.03, the Company
may:  (i) request the Affected Bank to use its best efforts to obtain a
replacement bank or financial institution satisfactory to the Company to acquire
and assume all or a ratable part of all of such Affected Bank's Loans and
Commitment (a "Replacement Bank"); (ii) request one or more of the other Banks
to acquire and assume all or part of such Affected Bank's Loans and Commitment;
or (iii) designate a Replacement Bank.  Any such designation of a Replacement
Bank under clause (i) or (iii) shall be subject to the prior written consent of
the Administrative Agent (which consent shall not be unreasonably withheld).

     3.09 Survival.  The agreements and obligations of the Company in this
Article III shall survive the payment of all other Obligations.

     3.10 Tax Forms.  Each Bank that is not incorporated under the laws of
the United States of America or a state thereof hereby certifies, as of the date
such Bank became a "Bank" hereunder, that, to its knowledge, it is entitled to
receive payments under this Agreement without deduction or withholding of any
United States federal income taxes.  In the event that any such Bank fails to
deliver any forms required under Section 9.10(a), each of the Company's and the
Borrowers' obligations to pay additional amounts to such Bank under this Article
III shall be reduced to the amount that they would have been obligated to pay
had such forms been provided.


                                   ARTICLE IV

property or the conduct of its business requires such qualification or license;
and (d) is in compliance with all Requirements of Law; except, in each case
referred to in clause (c) or clause (d), to the extent that the failure to do so
could not reasonably be expected to have a Material Adverse Effect.

     5.02 Corporate Authorization; No Contravention.  The execution, delivery
and performance by the Company and its Subsidiaries of this Agreement and each
other Loan Document to which such Person is party, have been duly authorized by
all necessary corporate action, and do not and will not: (a) contravene the

result in any breach or contravention of, in any material respect, any document
evidencing any material Contractual Obligation to which such Person is a party

properties which: (i) purport to affect or pertain to this Agreement or any
other Loan Document, or any of the transactions contemplated hereby or thereby;
or (ii) if determined adversely to the Company or its Subsidiaries, would
reasonably be expected to have a Material Adverse Effect.

     (b) No injunction, writ, temporary restraining order or any order of any
nature has been issued by any court or other Governmental Authority purporting
to enjoin or restrain the execution, delivery or performance of the Merger, the
Oil Field Merger, the EI Acquisition, this Agreement or any other Loan Document,
or directing that the transactions provided for herein or therein not be
consummated as herein or therein provided.

     5.06 No Default.  No Default or Event of Default exists or would result
from the incurring of any Obligations by the Company, the Borrowers or any of
the Guarantors.  As of the Closing Date, neither the Company nor any Subsidiary
is in default under or with respect to any Contractual Obligation in any respect
which, individually or together with all such defaults, could reasonably be
expected to have a Material Adverse Effect, or that would, if such default had
occurred after the Closing Date, create an Event of Default under subsection
8.01(e).

     5.07 ERISA Compliance.  Except as specifically disclosed in Schedule 5.07:

          (a) Each Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code and other federal or state law, except
where the failure to be in compliance would not, either individually or in the
aggregate, have a Material Adverse Effect.  The Company's Foreign Subsidiaries
and any benefit plans maintained by any of them for the benefit of their
directors, officers, employees or former employees (or any of their
beneficiaries) are in compliance with applicable laws pertaining to such plans
in the jurisdictions of such subsidiaries, except where such failure to be in
compliance would not, either individually or in the aggregate, have a Material
Adverse Effect.  Each Pension Plan which is intended to qualify under Section
401(a) of the Code has received a favorable determination letter from the IRS,
or filed with the IRS a request for (or is still within the applicable remedial
amendment period for filing) a favorable determination letter, and to the best
knowledge of the Company, nothing has occurred which would cause the loss of
such qualification.  The Company and each ERISA Affiliate has made all required
contributions to any Pension Plan subject to Section 412 of the Code, and no
application for a funding waiver or an extension of any amortization period
pursuant to Section 412 of the Code has been made with respect to any Pension
Plan.  Each Plan that is intended to be a voluntary employee benefit association
has been submitted to and approved by the IRS as exempt from federal income tax
under Section 501(c)(9) of the Code or the applicable submission period relating
to any such Plan will not have ended prior to the Closing Date.

          (b) There are no pending or, to the best knowledge of Company,
threatened claims, actions or lawsuits (other than routine claims for benefits),
or action by any Governmental Authority, with respect to any Plan which has
resulted or could reasonably be expected to result in a Material Adverse Effect.
There has been no prohibited transaction (unless the Plan received or is
entitled to an exemption under Section 408 of ERISA or Section 4975 of the Code,
as applicable, or unless such transaction has been corrected and all applicable
excise taxes paid or waived), or violation of the fiduciary

                                       35
<PAGE>
 
responsibility rules with respect to any Plan which has resulted or could
reasonably be expected to result in a Material Adverse Effect.

          (c) (i) No ERISA Event has occurred or is reasonably expected to
occur; (ii) as of the Closing Date, no Pension Plan has any Unfunded Pension
Liability; (iii) neither the Company nor any ERISA Affiliate has incurred, or
reasonably expects to incur, any liability (and no event has occurred which,
with the giving of notice under Section 4219 of ERISA, would result in such
liability) under Section 4201 or 4243 of ERISA with respect to a Multiemployer
Plan; and (iv) neither the Company nor any ERISA Affiliate has engaged in a
transaction that could be subject to Section 4069 or 4212(c) or ERISA.

     5.08 Use of Proceeds; Margin Regulations.  The proceeds of the Loans are to
be used solely for the purposes set forth in and permitted by Section 6.12 and
Section 7.05.  Neither the Company nor any Subsidiary is generally engaged in
the business of purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock.

     5.09 Title to Properties.  The Company and each of its Subsidiaries has
indefeasible title in fee simple to, or valid leasehold interests in, all real
property necessary or used in the ordinary conduct of their respective
businesses, except for such defects in title as could not, individually or in
the aggregate, have a Material Adverse Effect.  As of the Closing Date, the
property of the Company and its Subsidiaries is subject to no Liens, other than
Permitted Liens.

     5.10 Taxes.  The Company and its Subsidiaries have filed all Federal and
other material tax returns and reports required to be filed, and have paid all
Federal and other material taxes, assessments, fees and other governmental
charges levied or imposed upon them or their properties, income or assets
otherwise due and payable, except those which are being contested in good faith
by appropriate proceedings and for which adequate reserves have been provided in
accordance with GAAP. There is no proposed tax assessment against the Company or
any Subsidiary that would, if made, have a Material Adverse Effect.

     5.11 Financial Condition.  (a) The audited consolidated financial
statements of Weatherford and its Consolidated Subsidiaries dated December 31,
1994, and the related consolidated and consolidating statements of income,
shareholders' equity and cash flows for the fiscal year ended on that date: (i)
were prepared in accordance with GAAP consistently applied throughout the period
covered thereby, except as otherwise expressly noted therein; (ii) fairly
present the financial condition of Weatherford and its Consolidated Subsidiaries
as of the date thereof and results of operations for the period covered thereby;
and (iii)  except as specifically disclosed in Schedule 5.11, show all material
indebtedness and other liabilities, direct or contingent, of Weatherford and its
Consolidated Subsidiaries as of the date thereof, including liabilities for
taxes, material commitments and Contingent Obligations.

          (b) The audited consolidated financial statements of Enterra and its
Consolidated Subsidiaries dated December 31, 1994, and the related consolidated
and consolidating statements of income, shareholders' equity and cash flows for
the fiscal year

                                       36
<PAGE>
 
ended on that date: (i) were prepared in accordance with GAAP consistently
applied throughout the period covered thereby, except as otherwise expressly
noted therein; (ii) fairly present the financial condition of Enterra and its
Consolidated Subsidiaries as of the date thereof and the results of operation
for the period covered thereby; and (iii) except as specifically disclosed in
Schedule 5.11, show all material indebtedness and other liabilities, direct or
contingent, of Enterra and its Consolidated Subsidiaries as of the date thereof,
including liabilities for taxes, material commitments and Contingent
Obligations.

          (c) Since December 31, 1994, there has been no Material Adverse
Effect.

              (d)  The unaudited pro forma financial information contained in
the Joint Proxy Statement/Prospectus of Weatherford and Enterra on Form S-4
(Reg. No. 33-62195), based on the historical consolidated financial statements
identified therein, was prepared based upon assumptions deemed reasonable and
appropriate by Weatherford and Enterra when made; such assumptions continue to
be reasonable and appropriate as of the date of this Agreement; and nothing has
come to the attention of the Company on or before the Closing Date which has
caused, or could reasonably be expected to cause, the unaudited adjusted pro
forma balance sheet contained therein to be misleading in any material respect.

     5.12 Environmental Matters.  The Company and each of its Subsidiaries
monitors in the ordinary course of business the effect of existing Environmental
Laws and existing Environmental Claims on its business, operations and
properties, and as a result thereof the Company has reasonably concluded that,
except as specifically disclosed in Schedule 5.12, such Environmental Laws and
Environmental Claims could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

     5.13 Regulated Entities.  None of the Company, any Person controlling the
Company, or any Subsidiary, is an "Investment Company" within the meaning of the
Investment Company Act of 1940.  Neither the Company nor any of its Subsidiaries
is subject to regulation under the Public Utility Holding Company Act of 1935,
the Federal Power Act, the Interstate Commerce Act, any state public utilities
code, or any other Federal or state statute or regulation limiting, in any such
case, its ability to incur Indebtedness.

     5.14 No Burdensome Restrictions.  Neither the Company nor any Subsidiary is
a party to or bound by any Contractual Obligation, or subject to any restriction
in any Organization Document, or any Requirement of Law, which could reasonably
be expected to have a Material Adverse Effect.

     5.15 Copyrights, Patents, Trademarks and Licenses, etc. The Company and its
Subsidiaries own or are licensed or otherwise have the right to use all of the
patents, trademarks, service marks, trade names, copyrights, contractual
franchises, authorizations and other rights that are reasonably necessary for
the operation of their respective businesses, without conflict with the rights
of any other Person (except for any such conflict which could not reasonably be
expected to have a Material Adverse Effect).  To the best knowledge of the
Company, no slogan or other advertising device, product, process, method,
substance, part or other material now employed, or now contemplated to be
employed, by the Company or any Subsidiary infringes upon any rights held by any
other Person where

                                       37
<PAGE>
 
such infringement could reasonably be expected to have a Material Adverse
Effect.  Except as specifically disclosed in Schedule 5.05, no claim or
litigation regarding any of the foregoing is pending or threatened, and no
patent, invention, device, application, principle or any statute, law, rule,
regulation, standard or code is pending or, to the knowledge of the Company,
proposed, which, in either case, could reasonably be expected to have a Material
Adverse Effect.

     5.16 Subsidiaries.  As of the Closing Date (after giving effect to the
Merger), the Company has no Subsidiaries other than those specifically disclosed
in part (a) of Schedule 5.16 hereto and has no equity investments in any other
corporation or entity other than those specifically disclosed in part (b) of
Schedule 5.16.

     5.17 Insurance.  The properties of the Company and each of its Subsidiaries
are insured with financially sound and reputable insurance companies not
Affiliates of the Company, in such amounts, with such deductibles and covering
such risks as are customarily carried by companies engaged in similar businesses
and owning similar properties in localities where the Company or such Subsidiary
operates.

     5.18 Full Disclosure.  None of the representations or warranties made by
the Company or any Subsidiary in the Loan Documents as of the date such
representations and warranties are made or deemed made, and none of the
statements contained in any exhibit, report, statement or certificate furnished
by or on behalf of the Company or any Subsidiary in connection with the Loan
Documents (including the offering and disclosure materials delivered by or on
behalf of the Company to the Banks prior to the Closing Date), contains any
untrue statement of a material fact or omits any material fact required to be
stated therein or necessary to make the statements made therein, in light of the
circumstances under which they are made, not misleading as of the time when made
or delivered.

     5.19 Solvency.  Each of the Company and its Subsidiaries, taken as a whole,
and the Company, individually, each of the other Borrowers and each of the
Guarantors individually, is Solvent.  Each of the Borrowers and each of the
Guarantors has received at least a reasonably equivalent value in exchange for
incurring the obligations to be incurred by it.


                                   ARTICLE VI

                             AFFIRMATIVE COVENANTS

related consolidated and consolidating statements of income, shareholders'
equity and cash flows for such year, setting forth in each case in comparative

a nationally-recognized independent public accounting firm ("Independent
Auditor") which report shall state that such consolidated financial statements
present fairly the financial position and results of operations for the periods

          (c) of the occurrence of any of the following events affecting the
Company or any ERISA Affiliate (but in no event more than 10 days after the
Company obtains knowledge of such event), and deliver to the Administrative
Agent and each Bank a copy of any notice with respect to such event that is
filed with a Governmental Authority and any notice delivered by a Governmental
Authority to the Company or any ERISA Affiliate with respect to such event: (i)
an ERISA Event; (ii) a material increase in the Unfunded Pension Liability of
any Pension Plan; (iii) the adoption of, or the commencement of contributions

          (d) of any material change in accounting policies or financial

          (b) The Company and the other Borrowers shall cause each of their
respective Subsidiaries to preserve and maintain in full force and effect its
corporate existence and good standing under the laws of its state or
jurisdiction of incorporation, except where failure to do so could not
reasonably be expected to have a Material Adverse Effect.

          (c) The Company and the other Borrowers shall, and shall cause each of
their respective Subsidiaries to, preserve and maintain in full force and effect
all governmental rights, privileges, qualifications, permits, licenses and
franchises necessary or desirable in the normal conduct of their business except
in connection with transactions permitted by Section 7.03 and sales of assets
permitted by Section 7.02, except where failure to do so could not reasonably be
expected to have a Material Adverse Effect.

     6.05 Maintenance of Property.  The Company and the other Borrowers shall
maintain, and shall cause each of their respective Subsidiaries to maintain, and
preserve all their property which is used or useful in their business in good
working order and condition, ordinary wear and tear excepted and make all
necessary repairs thereto and renewals and replacements thereof except where the

Borrowers and each of their respective Subsidiaries shall use the standard of
care typical in the industry in the operation and maintenance of their
facilities.

     6.06 Insurance.  The Company and the other Borrowers shall maintain, and

such amounts as are customarily carried under similar circumstances by such
other Persons.

     6.07 Payment of Certain Obligations.  The Company and the other Borrowers
shall, and shall cause each of their respective Subsidiaries to, pay and
discharge as the same shall become due and payable (or, in the case of tax
liabilities, before they become delinquent), all their respective obligations
and liabilities, including: (a) all tax liabilities, assessments and
governmental charges or levies upon them or their properties or assets, unless
the same are being contested in good faith by appropriate proceedings and
adequate reserves in accordance with GAAP are being maintained by the Company,
the other Borrowers or such Subsidiaries; and (b) all lawful claims which, if
unpaid, would by law become a Lien upon their property.

     6.08 Compliance with Laws.  The Company and the other Borrowers shall
comply, and shall cause each of their respective Subsidiaries to comply, in all
material respects with all Requirements of Law of any Governmental Authority
having jurisdiction over them or their business (including the Federal Fair

the Company and the applicable other Borrower(s) and at such reasonable times
during normal business hours and as often as may be reasonably desired, upon
reasonable advance notice to the Company and the applicable other Borrower(s);
provided, however, when an Event of Default exists the Administrative Agent or
any Bank may do any of the foregoing at the expense of the Company and the
applicable other Borrower(s) at any time during normal business hours and
without advance notice.

     6.11 Environmental Laws.  The Company and the other Borrowers shall, and

Agreement, there exists any Subsidiary incorporated in the United States of
America with total assets with a book value of $10,000,000 or more, then the
Company shall cause each such Subsidiary to do the following within 30 days

$10,000,000 or more:  (i) execute and deliver a Guaranty to the Administrative
Agent substantially in the form of Exhibit B-2 hereto and (ii) furnish the
Administrative Agent with a written opinion of counsel for each such Subsidiary

     So long as any Bank shall have any Commitment hereunder, or any Loan or
other Obligation shall remain unpaid or unsatisfied, unless the Majority Banks
consent in writing:

indirectly, make, create, incur, assume or suffer to exist any Lien upon or with
respect to any part of their property, whether now owned or hereafter acquired,

intended by the Company, the other Borrowers or any of their respective
Subsidiaries to provide collateral to the depository institution;

<PAGE>
 
          (a) declare the commitment of each Bank to make Loans to be
terminated, whereupon such commitments and obligation shall be terminated;

          (b) declare the unpaid principal amount of all outstanding Loans, all
interest accrued and unpaid thereon, and all other amounts owing or payable

acceleration or other notice of any kind, all of which are hereby expressly
waived by the Company; and

          (c) exercise on behalf of itself and the Banks all rights and remedies

Sections 7.10, 7.11 or 7.12, as of such fiscal period end date, such Event of
Default shall be deemed to arise upon the earlier of (a) the date after such
fiscal period end date on which the Company announces publicly it will take, is

                            THE ADMINISTRATIVE AGENT

     9.01 Appointment and Authorization.  Each Bank hereby irrevocably (subject
to Section 9.09) appoints, designates and authorizes the Administrative Agent to
take such action on its behalf under the provisions of this Agreement and each
other Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it, by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Administrative Agent shall

                                       50
<PAGE>
 
not have any duties or responsibilities, except those expressly set forth
herein, nor shall the Administrative Agent have or be deemed to have any
fiduciary relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent.

     9.02 Delegation of Duties.  The Administrative Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel

attorney-in-fact that it selects with reasonable care, and the Administrative
Agent shall not be responsible in any event for the negligence or misconduct of
any agent or attorney-in-fact selected by any other agent.

     9.03 Liability of Agent-Related Person.  None of the Agent-Related Persons

misconduct), or (ii) be responsible in any manner to any of the Banks for any
recital, statement, representation or warranty made by the Company or any
Subsidiary or Affiliate of the Company, or any officer thereof, contained in
this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or any other
Loan Document, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
the Company or any other party to any Loan Document to perform its obligations
hereunder or thereunder.  No Agent-Related Person shall be under any obligation
to any Bank to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the properties, books or records of the
Company or any of the Company's Subsidiaries or Affiliates.

     9.04 Reliance by Administrative Agent.

          (a) The Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel, independent accountants and
other experts selected by the Administrative Agent.  The Administrative Agent
shall be fully justified in failing or refusing to take any action under this
Agreement or any other Loan Document unless it shall first receive such advice
or concurrence of the Majority Banks as it deems appropriate and, if it so
requests, it shall first be indemnified to its satisfaction by the Banks against
any and all liability and expense which may be incurred by it by reason of
taking or continuing to take any such action.  The Administrative Agent shall in
all cases be fully protected in acting, or in refraining from acting, under this
Agreement or any other Loan Document in accordance with a request or consent of
the Majority Banks (or otherwise as required pursuant to Section 10.01) and such

                                       51
<PAGE>
 
request and any action taken or failure to act pursuant thereto shall be binding
upon all of the Banks.

          (b) For purposes of determining compliance with the conditions
specified in Section 4.01, each Bank that has executed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Administrative Agent to such Bank
for consent, approval, acceptance or satisfaction, or required thereunder to be
consented to or approved by or acceptable or satisfactory to the Bank.

     9.05 Notice of Default.  The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Banks,
unless the Administrative Agent shall have received written notice from a Bank
or the Company referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default".  The
Administrative Agent will notify the Banks of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be requested by the Majority Banks in accordance with
Article IX; provided, however, that unless and until the Administrative Agent
has received any such request, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Banks.

     9.06 Credit Decision.  Each Bank acknowledges that none of the Agent-
Related Persons has made any representation or warranty to it, and that no act
by any Agent hereinafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Bank.  Each Bank represents to
the Agents that it has, independently and without reliance upon any Agent-
Related Person and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Company and its Subsidiaries, and all applicable bank
regulatory laws relating to the transactions contemplated hereby, and made its
own decision to enter into this Agreement and to extend credit to the Company
and its Subsidiaries hereunder.  Each Bank also represents that it will,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Company, the Borrower, the Guarantors and all other
parties to the Loan Documents.  Except for notices, reports and other documents
expressly herein required to be furnished to the Banks by the Administrative
Agent, the Administrative Agent shall not have any duty or responsibility to
provide any Bank with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or
creditworthiness of the Company or its Subsidiaries which may come into the
possession of any of the Agent-Related Persons.

                                       52
<PAGE>
 
     9.07 Indemnification.  Whether or not the transactions contemplated hereby
are consummated, the Banks shall indemnify upon demand the Agent-Related Persons
(to the extent not reimbursed by or on behalf of the Company and without
limiting the obligation of the Company to do so), pro rata, from and against any
and all Indemnified Liabilities; provided, however, that no Bank shall be liable
for the payment to the Agent-Related Persons of any portion of such Indemnified
Liabilities resulting solely from such Person's gross negligence or willful
misconduct.  Without limitation of the foregoing, each Bank shall reimburse the
Agents upon demand for its ratable share of any costs or out-of-pocket expenses
(including Attorney Costs) incurred by such Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement,
any other Loan Document, or any document contemplated by or referred to herein,
to the extent that such Agent is not reimbursed for such expenses by or on
behalf of the Company.  The undertaking in this Section shall survive the
payment of all Obligations hereunder and the resignation or replacement of any
Agent.

     9.08 Agents in Individual Capacities.  TCB, BofA and their respective
Affiliates may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory, underwriting or other business with the
Company and its Subsidiaries and Affiliates as though TCB were not the
Administrative Agent and as if BofA were not the Documentation Agent and without
notice to or consent of the Banks.  The Banks acknowledge that, pursuant to such
activities, TCB, BofA and their respective Affiliates may receive information
regarding the Company or its Affiliates (including information that may be
subject to confidentiality obligations in favor of the Company or such
Subsidiary) and acknowledge that the Agents shall be under no obligation to
provide such information to them.  With respect to its Loans, each of TCB and
BofA shall have the same rights and powers under this Agreement as any other
Bank and may exercise the same as though it were not an Agent hereunder.

     9.09 Successor Agent.  The Administrative Agent may, and at the request of
the Majority Banks shall, resign as Administrative Agent upon 30 days' notice to
the Banks, with a copy of such notice to the Company.  If the Administrative
Agent resigns under this Agreement, the Majority Banks shall appoint from among
the Banks a successor agent for the Banks.  If no successor agent is appointed
prior to the effective date of the resignation of the Administrative Agent, the
Administrative Agent may appoint, after consulting with the Banks and the
Company, a successor agent from among the Banks.  Upon the acceptance of its
appointment as successor agent hereunder, such successor agent shall succeed to
all the rights, powers and duties of the retiring Administrative Agent and the
term "Administrative Agent" shall mean such successor agent and the retiring
Administrative Agent's appointment, powers and duties as Administrative Agent
shall be terminated. After any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the provisions of this Article IX and
Sections 10.04 and 10.05 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this
Agreement.  If no successor agent has accepted appointment as Administrative
Agent by the date which is 30 days following a retiring Administrative Agent's
notice of resignation, the retiring Administrative Agent's resignation shall
nevertheless thereupon become effective

                                       53
<PAGE>
 
and the Banks shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Majority Banks appoint a successor
agent as provided for above.

     9.10 Withholding Tax.

          (a) If any Bank is a "foreign corporation, partnership or trust"
within the meaning of the Code and such Bank claims exemption from, or a
reduction of, U.S. withholding tax under Sections 1441 or 1442 of the Code, such
Bank agrees with and in favor of the Administrative Agent, to deliver to the
Administrative Agent (with a copy to the Company):

               (i) if such Bank claims an exemption from, or a reduction of,
     withholding tax under a United States tax treaty, properly completed IRS
     Forms 1001 and W-8 before the payment of any interest in the first calendar
     year and before the payment of any interest in each third succeeding
     calendar year during which interest may be paid under this Agreement;

               (ii) if such Bank claims that interest paid under this Agreement
     is exempt from United States withholding tax because it is effectively
     connected with a United States trade or business of such Bank, two properly
     completed and executed copies of IRS Form 4224 before the payment of any
     interest is due in the first taxable year of such Bank and in each
     succeeding taxable year of such Bank during which interest may be paid
     under this Agreement, and IRS Form W-9; and

               (iii)  such other form or forms as may be required under the Code
     or other laws of the United States as a condition to exemption from, or
     reduction of, United States withholding tax.

Such Bank agrees to promptly notify the Administrative Agent of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction.
          (b) If any Bank claims exemption from, or reduction of, withholding
tax under a United States tax treaty by providing IRS Form 1001 and such Bank
sells, assigns, grants a participation in, or otherwise transfers all or part of
the Obligations to such Bank, such Bank agrees to notify the Administrative
Agent of the percentage amount in which it is no longer the beneficial owner of
Obligations to such Bank.  To the extent of such percentage amount, the
Administrative Agent will treat such Bank's IRS Form 1001 as no longer valid.

          (c) If any Bank claiming exemption from United States withholding tax
by filing IRS Form 4224 with the Administrative Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations to such
Bank, such Bank agrees to undertake sole responsibility for complying with the
withholding tax requirements imposed by Sections 1441 and 1442 of the Code.

          (d) If any Bank is entitled to a reduction in the applicable
withholding tax, the Administrative Agent may withhold from any interest payment
to such Bank an amount

                                       54
<PAGE>
 
equivalent to the applicable withholding tax after taking into account such
reduction.  If the forms or other documentation required by subsection (a) of
this Section are not delivered to the Administrative Agent, then the
Administrative Agent may withhold from any interest payment to such Bank not
providing such forms or other documentation an amount equivalent to the
applicable withholding tax.

          (e) If the IRS or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that the Administrative Agent did
not properly withhold tax from amounts paid to or for the account of any Bank
(because the appropriate form was not delivered, was not properly executed, or
because such Bank failed to notify the Administrative Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason) such Bank shall indemnify the
Administrative Agent fully for all amounts paid, directly or indirectly, by the
Administrative Agent as tax or otherwise, including penalties and interest, and
including any taxes imposed by any jurisdiction on the amounts payable to the
Administrative Agent under this Section, together with all costs and expenses
(including Attorney Costs).  The obligation of the Banks under this subsection
shall survive the payment of all Obligations and the resignation or replacement
of the Administrative Agent.

     9.11 Documentation Agent; Senior Co-Agent; Co-Agents; Arrangers.  None of
the Banks identified on the facing page, signature pages or otherwise herein of
this Agreement as "Documentation Agent," "Senior Co-Agent," "Co-Agent" or
"Arranger" shall have any right, power, obligation, liability, responsibility or
duty under this Agreement other than those applicable to all Banks.  Without
limiting the foregoing, none of the Banks so identified as a "Documentation
Agent," "Senior Co-Agent," "Co-Agent" or "Arranger" shall have or be deemed to
have any fiduciary relationship with any Bank.  Each Bank acknowledges that it
has not relied, and will not rely, on any of the Banks so identified in deciding
to enter into this Agreement or in taking or not taking action hereunder.

amendment, waiver or consent shall, unless in writing and signed by the

Majority Banks or all of the Banks, as the case may be, affect the rights and
duties of the Documentation Agent or affected Arranger, as applicable, under
this Agreement or any other Loan Document, and (iii) the Administrative Agent's
Letter, the Fee Letter and the Invitation Letters, respectively, may be amended,
or rights or privileges thereunder waived, in a writing executed by the parties
thereto.

     10.02  Notices.

          (a) All notices, requests and other communications shall be in writing
(including, unless the context expressly otherwise provides, by facsimile
transmission, provided that any matter transmitted by the Company, any Borrower,
any Guarantor or any of their respective Subsidiaries by facsimile (i) shall be
immediately confirmed by a telephone call to the recipient at the number
specified on Schedule 10.02, and (ii) shall be followed promptly by delivery of
a hard copy original thereof) and mailed, faxed or delivered, to the address or
facsimile number specified for notices on Schedule 10.02; or, as directed to the
Company or the Administrative Agent, to such other address as shall be
designated by such party in a written notice to the other parties, and as

                                       56
<PAGE>
 
          (c) Any agreement of the Administrative Agent and the Banks herein to
receive certain notices by telephone or facsimile is solely for the convenience
and at the request of the Company.  The Administrative Agent and the Banks shall
be entitled to rely on the authority of any Person purporting to be a Person
authorized by the Company or any Borrower to give such notice and the
Administrative Agent and the Banks shall not have any liability to the Company
or any Borrower or other Person on account of any action taken or not taken by
the Administrative Agent or the Banks in reliance upon such telephonic or
facsimile notice.  The obligation of the Company or any Borrower to repay the
Loans shall not be affected in any way or to any extent by any failure by the
Administrative Agent and the Banks to receive written confirmation of any
telephonic or facsimile notice or the receipt by the Administrative Agent and
the Banks of a confirmation which is at variance with the terms understood by
the Administrative Agent and the Banks to be contained in the telephonic or
facsimile notice.

     10.03  No Waiver; Cumulative Remedies.  No failure to exercise and no delay
in exercising, on the part of the Administrative Agent or any Bank, any right,
remedy, power or privilege hereunder, shall operate as a waiver thereof;  nor
shall any single or partial exercise of any right, remedy, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege.

     10.04  Costs and Expenses.  The Company and the Borrowers jointly and
severally agree that they shall:

          (a) whether or not the transactions contemplated hereby are
consummated, pay or reimburse BofA (including in its capacity as Documentation
Agent) and TCB (including in its capacity as Administrative Agent) within five
(5) Business Days after demand (subject to subsection 4.01(g)) for all
reasonable costs and expenses incurred by BofA and/or TCB, as applicable, in
connection with the development, preparation, delivery, administration and
execution of, and any amendment, supplement, waiver or modification to (in each
case, whether or not consummated), this Agreement, any Loan Document and any
other documents prepared in connection herewith or therewith, and the
consummation of the transactions contemplated hereby and thereby, including
reasonable Attorney Costs incurred by BofA and/or TCB, as applicable, with
respect thereto; and

          (b) pay or reimburse the Agents, the Arranger and each Bank within
five (5) Business Days after demand (subject to subsection 4.01(g)) for all
costs and expenses (including Attorney Costs) incurred by them in connection
with the enforcement, attempted enforcement, or preservation of any rights or
remedies under this Agreement or any other Loan Document during the existence of
an Event of Default or after acceleration of the Loans (including in connection
with any "workout" or restructuring regarding the Loans, and including in any
Insolvency Proceeding or appellate proceeding).

     10.05  Indemnity.  Whether or not the transactions contemplated hereby are
consummated, the Company and each of the Borrowers, jointly and severally, shall
indemnify and hold the Agent-Related Persons, and each Bank and each of its
respective officers, directors, employees, counsel, agents and attorneys-in-fact
(each, an "Indemnified Person") harmless from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, charges, expenses and disbursements (including

                                       57
<PAGE>
 
Attorney Costs) of any kind or nature whatsoever which may at any time
(including at any time following repayment of the Loans and the termination,
resignation or replacement of the Administrative Agent or replacement of any
Bank)  be imposed on, incurred by or asserted against any such Person in any way
relating to or arising out of this Agreement or any document contemplated by or
referred to herein, or the transactions contemplated hereby, or any action taken
or omitted by any such Person under or in connection with any of the foregoing,
including with respect to any investigation, litigation or proceeding (including
any Insolvency Proceeding or appellate proceeding) related to or arising out of
this Agreement or the Loans or the use of the proceeds thereof, whether or not
any Indemnified Person is a party thereto (all the foregoing, collectively, the
"Indemnified Liabilities"); provided, that the Company and the Borrowers shall
have no obligation hereunder to any Indemnified Person with respect to
Indemnified Liabilities resulting solely from the gross negligence or willful
misconduct of such Indemnified Person. The agreements in this Section shall
survive payment of all other Obligations.

     10.06  Payments Set Aside.  To the extent that the Company, any Borrower or
any Guarantor makes a payment to the Administrative Agent or the Banks, or the
Administrative Agent or the Banks exercise their right of set-off, and such
payment or the proceeds of such set-off or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Administrative Agent
or such Bank in its discretion) to be repaid to a trustee, receiver or any other
party, in connection with any Insolvency Proceeding or otherwise, then (a) to
the extent of such recovery the obligation or part thereof originally intended
to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such set-off had not occurred, and (b) each
Bank severally agrees to pay to the Administrative Agent upon demand its Pro
Rata Share of any amount so recovered from or repaid by the Administrative
Agent.

     10.07  Successors and Assigns.  The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that neither the Company nor any Borrower may
assign or transfer any of its rights or obligations under this Agreement without
the prior written consent of the Administrative Agent and each Bank.

     10.08  Assignments, Participations, etc.

          (a) Any Bank may, with the written consent of the Company at all times
other than during the existence of an Event of Default and the Administrative
Agent, which consents of the Company and the Administrative Agent shall not be
unreasonably withheld, at any time assign and delegate to one or more Eligible
Assignees (provided that no written consent of the Company or the Administrative
Agent shall be required in connection with any assignment and delegation by a
Bank to an Eligible Assignee that is an Affiliate of such Bank) (each an
"Assignee") all, or any ratable part of all, of the Loans, the Commitments, and
the other rights and obligations of such Bank hereunder, in a minimum amount of
$10,000,000; provided, however, that the Company, the Borrowers and the
Administrative Agent may continue to deal solely and directly with such Bank in
connection with the interest so assigned to an Assignee until (i) written notice
of such assignment, together with payment instructions, addresses and related
information with respect to the Assignee, shall

                                       58
<PAGE>
 
have been given to the Company and the Administrative Agent by such Bank and the
Assignee; (ii) such Bank and its Assignee shall have delivered to the Company
and the Administrative Agent an Assignment and Acceptance in the form of Exhibit
H ("Assignment and Acceptance") together with any Note or Notes subject to such
assignment and (iii) the assignor Bank or Assignee has paid to the
Administrative Agent a processing fee in the amount of $2,500; provided,
further, that in the event a Bank assigns less than all of its interests
hereunder, it shall retain a Commitment of not less than $10,000,000 after the
consummation of the assignment.

          (b) From and after the date that the Administrative Agent notifies the
assignor Bank that it has received (and provided its consent with respect to) an
executed Assignment and Acceptance and payment of the above-referenced
processing fee, (i) the Assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, shall have the rights and obligations of a
Bank under the Loan Documents, and (ii) the assignor Bank shall, to the extent
that rights and obligations hereunder and under the other Loan Documents have
been assigned by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under the Loan Documents.

          (c) Within five (5) Business Days after its receipt of notice by the
Administrative Agent that it has received an executed Assignment and Acceptance
and payment of the processing fee, (and provided that it consents to such
assignment in accordance with subsection 10.08(a)), the Borrowers shall execute
and deliver to the Administrative Agent, new Notes evidencing such Assignee's
assigned Loans and Commitment and, if the assignor Bank has retained a portion
of its Loans and its Commitment, replacement Notes in the principal amount of
the Loans retained by the assignor Bank (such Notes to be in exchange for, but
not in payment of, the Notes held by such Bank).  Immediately upon each
Assignee's making its processing fee payment under the Assignment and
Acceptance, this Agreement shall be deemed to be amended to the extent, but only
to the extent, necessary to reflect the addition of the Assignee and the
resulting adjustment of the Commitments arising therefrom. The Commitment
allocated to each Assignee shall reduce such Commitments of the assigning Bank
pro tanto.

          (d) Any Bank may at any time sell to one or more commercial banks or
other Persons not Affiliates of the Company (a "Participant") participating
interests in any Loans, the Commitment of that Bank and the other interests of
that Bank (the "originating Bank") hereunder and under the other Loan Documents;
provided, however, that (i) the originating Bank's obligations under this
Agreement shall remain unchanged, (ii) the originating Bank shall remain solely
responsible for the performance of such obligations, (iii) the Company, the
Borrowers and the Administrative Agent shall continue to deal solely and
directly with the originating Bank in connection with the originating Bank's
rights and obligations under this Agreement and the other Loan Documents, and
(iv) no Bank shall transfer or grant any participating interest under which the
Participant has rights to approve any amendment to, or any consent or waiver
with respect to, this Agreement or any other Loan Document, except to the extent
such amendment, consent or waiver would require unanimous consent of the Banks
as described in the first proviso to Section 10.01. In the case of any such
participation, the Participant shall be entitled to the benefit of Article III
and Section 10.05 as though it were also a Bank hereunder, and if amounts
outstanding

                                       59
<PAGE>
 
under this Agreement are due and unpaid, or shall have been declared or shall
have become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of set-off in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Bank under this Agreement.

          (e) Each Bank agrees to take normal and reasonable precautions and
exercise due care to maintain the confidentiality of all information identified
as "confidential" or "secret"  by the Company and provided to it by the Company
or any Subsidiary, or by the Administrative Agent on such Company's or
Subsidiary's behalf, under this Agreement or any other Loan Document, and
neither it nor any of its Affiliates shall use any such information other than
in connection with or in enforcement of this Agreement and the other Loan
Documents; except to the extent such information (i) was or becomes generally
available to the public other than as a result of disclosure by the Bank, or
(ii) was or becomes available on a  non-confidential basis from a source other
than the Company, provided that such source is not bound by a confidentiality
agreement with the Company known to the Bank; provided, however, that any Bank
may disclose such information (A) at the request or pursuant to any requirement
of any Governmental Authority to which the Bank is subject or in connection with
an examination of such Bank by any such authority; (B) pursuant to subpoena or
other court process; (C) when required to do so in accordance with the
provisions of any applicable Requirement of Law; (D) to the extent reasonably
required in connection with any litigation or proceeding to which any Agent, any
Bank or their respective Affiliates may be party; (E) to the extent reasonably
required in connection with the exercise of any remedy hereunder or under any
other Loan Document; (F) to such Bank's independent auditors and other
professional advisors; (G) to any Affiliate of such Bank, or to any Participant
or Assignee, actual or potential, provided that such Affiliate, Participant or
Assignee agrees to keep such information confidential to the same extent
required of the Banks hereunder, and (H) as to any Bank, as expressly permitted
under the terms of any other document or agreement regarding confidentiality to
which the Company is party or is deemed party with such Bank.

          (f) Notwithstanding any other provision in this Agreement, any Bank
may at any time create a security interest in, or pledge, all or any portion of
its rights under and interest in this Agreement and the Notes held by it in
favor of any Federal Reserve Bank in accordance with Regulation A of the FRB or
U.S. Treasury Regulation 31 CFR (S)203.14, and such Federal Reserve Bank may
enforce such pledge or security interest in any manner permitted under
applicable law.

     10.09  Set-off.  In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Company or the Borrowers or the Guarantors, any such notice
being waived by the Company and the Borrowers and the Guarantors to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held by, and other
indebtedness at any time owing by, such Bank to or for the credit or the account
of the Company or any Borrower or Guarantor against any and all Obligations
owing to such Bank, now or hereafter existing, irrespective of whether or not
the Administrative Agent or such Bank shall have made demand under this
Agreement or any Loan Document and

                                       60
<PAGE>
 
although such Obligations may be contingent or unmatured.  Each Bank agrees
promptly to notify the Company and the Administrative Agent after any such set-
off and application made by such Bank; provided, however, that the failure to
give such notice shall not affect the validity of such set-off and application.

     10.10  Notification of Addresses, Lending Offices, Etc.  Each Bank shall
notify the Administrative Agent in writing of any changes in the address to
which notices to the Bank should be directed, of addresses of any Lending
Office, of payment instructions in respect of all payments to be made to it
hereunder and of such other administrative information as the Administrative
Agent shall reasonably request.

     10.11  Counterparts.  This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

     10.12  Severability.  The illegality or unenforceability of any provision
of this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

     10.13  No Third Parties Benefitted.  This Agreement is made and entered
into for the sole protection and legal benefit of the Company, the Borrowers,
the Banks, the Agents, the Senior Co-Agent, the Co-Agents and the Agent-Related
Persons, and their permitted successors and assigns, and no other Person shall
be a direct or indirect legal beneficiary of, or have any direct or indirect
cause of action or claim in connection with, this Agreement or any of the other
Loan Documents.

     10.14  GOVERNING LAW AND JURISDICTION.

          (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICT

RIGHTS ARISING UNDER FEDERAL LAW.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR

AND ALL LEGAL PROCESS, SUMMONS, NOTICES AND DOCUMENTS WHICH MAY BE SERVED IN ANY
SUCH ACTION OR PROCEEDING.  IF FOR ANY REASON SUCH DESIGNEE, APPOINTEE AND AGENT
SHALL CEASE TO BE AVAILABLE TO ACT AS SUCH, THE BORROWERS AGREE TO DESIGNATE A
NEW DESIGNEE, APPOINTEE AND AGENT IN NEW YORK ON THE TERMS AND FOR THE PURPOSES
OF THIS PROVISION SATISFACTORY TO THE ADMINISTRATIVE AGENT.  TO THE EXTENT

THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR

     10.16  Interest.  It is the intention of the parties hereto to comply with
applicable usury laws; accordingly, notwithstanding any provision to the
contrary in this Agreement, the Notes or in any of the other Loan Documents
securing the payment hereof or otherwise relating hereto, in no event shall this
Agreement, the Notes or such other Loan Documents require the payment or permit
the payment, taking, reserving, receiving, collection or charging of any sums
constituting interest under applicable laws, if any, which exceed the maximum
amount permitted by such laws.  If any such excess interest is called for,
contracted for, charged, taken, reserved, or received in connection with the
Loans evidenced by the Notes or in any of the Loan Documents securing the
payment thereof or otherwise relating thereto, or in any communication by the
Agents or the Banks or any other person to any Borrower or any other person, or
in the event all or part of the principal or interest thereof shall be prepaid
or accelerated, so that under any of such circumstances or under any other
circumstance whatsoever the amount of interest contracted for, charged, taken,
reserved, or received on the amount of principal actually outstanding from time
to time under the Notes shall exceed the maximum amount of interest permitted by
applicable usury laws, then in any such event it is agreed as follows:  (i) the
provisions of this paragraph shall govern and control, (ii) neither any Borrower
nor any other person or entity now or hereafter liable for the payment of the
Notes shall be obligated to pay the amount of such interest to the extent such
interest is in excess of the maximum amount of interest permitted by applicable
usury laws, (iii) any such excess which is or has been received notwithstanding
this paragraph shall be credited against the then unpaid principal balance of
the Notes or, if the Notes have been or would be paid in full, refunded to the
applicable Borrower, and (iv) the provisions of this Agreement, the Notes and
the other Loan Documents securing the payment hereof and otherwise relating
hereto, and any communication to any Borrower, shall immediately be deemed
reformed and such excess interest reduced, without the necessity of executing
any other document, to the maximum lawful rate allowed under applicable laws as
now or hereafter construed by courts having jurisdiction hereof or thereof.
Without limiting the foregoing, all calculations of the rate of interest
contracted for, charged, taken, reserved, or received in connection with the
Notes or this Agreement which are made for the purpose of determining whether
such rate exceeds the maximum lawful rate shall be made to the extent permitted
by applicable laws by amortizing, prorating, allocating and spreading during the
period of the full term of the Loans, including all prior and subsequent
renewals and extensions, all interest at any time contracted for, charged,
taken, reserved, or received.  The terms of this paragraph shall be deemed to be
incorporated in every document and communication relating to the Notes, the
Loans or any other Loan Document.

     10.17  Company as Subsidiary Borrower Representative.  Each Subsidiary
Borrower hereby irrevocably designates and appoints the Company as the agent of
such Subsidiary Borrower under this Agreement and the other Loan Documents for
the purpose of giving notices and taking other actions delegated to the Company
pursuant to the terms of this Agreement and the other Loan Documents.  In
furtherance of the foregoing, each Subsidiary Borrower hereby irrevocably grants
to the Company such Subsidiary Borrower's power-of-attorney, and hereby
authorizes the Company, to act in place of such Subsidiary Borrower with respect
to matters delegated to the Company pursuant to the terms of this Agreement and
the other Loan Documents and to take such other actions as are reasonably
incidental thereto.  The Company hereby agrees to provide prompt notice to the
relevant Subsidiary Borrower of any action taken by the Company under this
Agreement and the other Loan

                                       63
<PAGE>
 
Documents in place of such Subsidiary Borrower; provided, that the failure to so
provide such notice shall not affect the obligations of such Subsidiary Borrower
hereunder.  The Agent is hereby authorized to direct to the Company all invoices
and similar statements showing amounts due by the Borrowers hereunder and under
the Notes.

     10.18  Indemnity and Subrogation.  In addition to all such rights of
indemnity and subrogation as the Guarantors may have under applicable law, each
Borrower agrees that in the event a payment shall be made by any Guarantor under
a Guaranty in respect of a Loan to such Borrower, such Borrower shall indemnify
such Guarantor for the full amount of such payment and such Guarantor shall be
subrogated to the rights of the person to whom such payment shall have been made
to the extent of such payment subject to the provisions of the Guaranty executed
by such Guarantor.  Notwithstanding any provision of this Agreement to the
contrary, all rights of the Guarantors under this Section 10.18 and all other
rights of indemnity, contribution or subrogation under applicable law or
otherwise shall be fully subordinated to the indefeasible payment in full of the
Obligations.  No failure on the part of a Borrower to make the payments required
by this Section (or any other payments required under applicable law or
otherwise) shall in any respect limit the obligations and liabilities of any
Guarantor with respect to any Guaranty, and each Guarantor shall remain liable
for the full amount of the obligations of such Guarantor under each such
Guaranty in accordance therewith.

     10.19  Entire Agreement.  This Agreement supersedes in its entirety, the
commitment letter dated August 28, 1995, among Weatherford, BofA, TCB and the
Arrangers, which letter is hereby terminated.  The Fee Letter, the
Administrative Agent's Letter and the Invitation Letters remain in full force
and effect in accordance with their terms.  This Agreement, together with the
other Loan Documents, embodies the entire agreement and understanding among the
Company, the Banks and the Agents, and supersedes all prior or contemporaneous
agreements and understandings of such Persons, verbal or written, relating to
the subject matter hereof and thereof.

     THIS WRITTEN LOAN AGREEMENT, TOGETHER WITH THE OTHER WRITTEN LOAN DOCUMENTS
EXECUTED IN CONNECTION HEREWITH, REPRESENTS THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

     THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed and delivered by their proper and duly authorized officers as of
the day and year first above written.

                          CHANGE OF CONTROL AGREEMENT

     This Change of Control Agreement by and between Weatherford Enterra, Inc.,
a Delaware corporation (the "Company"), and M. Timothy Carey (the "Executive"),
dated as of October 5, 1995.

                                   RECITALS:

     A.   The Board of Directors of the Company (the "Board") has previously
determined that it is in the best interests of the Company and its stockholders
to assure that the Company will have the continued dedication of the Executive,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Company.  The Board believes it is imperative to diminish
the inevitable distraction of the Executive by virtue of the personal
uncertainties and risks created by a pending or threatened Change of Control and
to encourage the Executive's full attention and dedication to the Company
currently and in the event of any threatened or pending Change of Control, and
to provide the Executive with compensation and benefits arrangements upon a
Change of Control which ensure that the compensation and benefits expectations
of the Executive, which are competitive with those of executives at other
corporations, will be satisfied.

     B.   To accomplish these objectives, the Board has caused the Company to
enter into this Agreement.

     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.   Certain Definitions.

          (a) The "Effective Date" shall mean the first date during the Change
of Control Period (as defined in Section 1(b)) on which a Change of Control (as
defined in Section 2) occurs.  Anything in this Agreement to the contrary
notwithstanding, if a Change of Control occurs and if the Executive's employment
with the Company is terminated prior to the date on which the Change of Control
occurs, and if it is reasonably demonstrated by the Executive that such
termination of employment (i) was at the request of a third party who has taken
steps reasonably calculated to effect a Change of Control or (ii) otherwise
arose in connection with or anticipation of a Change of Control, then for all
purposes of this Agreement the "Effective Date" shall mean the date immediately
prior to the date of such termination of employment.

          (b) The "Change of Control Period" shall mean the period commencing on
the date hereof and ending on the second anniversary of the date hereof;
provided, 

                                       1
<PAGE>
 
however, that commencing on the date one year after the date hereof,
and on each annual anniversary of such date (such date and each annual
anniversary thereof shall be hereinafter referred to as the "Renewal Date"),
unless previously terminated, the Change of Control Period shall be
automatically extended so as to terminate two year(s) after such Renewal Date,
unless at least 60 days prior to the Renewal Date the Company shall give notice
to the Executive that the Change of Control Period shall not be so extended.

     2.   Change of Control.  For the purpose of this Agreement, a "Change of
Control" shall mean:

          (a) The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however that for purposes of this subsection (a), the following
acquisitions shall not constitute a Change of Control:

          (i) any acquisition directly from the Company,

          (ii) any acquisition by the Company,

          (iii) any acquisition by any employee benefit plan (or related trust)
sponsored or maintained by the Company or any corporation controlled by the
Company, or

          (iv) any acquisition by any corporation pursuant to a transaction
which complies with clauses (i), (ii) and (iii) of subsection (c) of this
Section 2; or

          (b) Individuals, who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual was a member of the Incumbent Board, but excluding, for this purpose,
any such individual whose initial assumption of office occurs as a result of an
actual or threatened election contest with respect to the election or removal of
directors or other actual or threatened solicitation of proxies or consents by
or on behalf of a Person other than the Board; or

                                       2
<PAGE>
 
          (c) Consummation of a reorganization, merger or consolidation or sale
or other disposition of all or substantially all of the assets of the Company (a
"Corporate Transaction") in each case, unless, following such Corporate
Transaction, (i) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities immediately prior to such
Corporate  Transaction beneficially own, directly or indirectly, more than 60
percent of, respectively, the then outstanding shares of common stock and the
combined voting power of the then outstanding voting securities entitled to vote
generally in the election of directors, as the case may be, of the corporation
resulting from such Corporate Transaction (including, without limitation, a
corporation which as a result of such transaction owns the Company or all or
substantially all of the Company's assets either directly or through one or more
subsidiaries) in substantially the same proportions as their ownership,
immediately prior to such Corporate Transaction, of the Outstanding Company
Common Stock and the Outstanding Company Voting Securities, as the case may be,
(ii) no Person (excluding any corporation resulting from such Corporate
Transaction or any employee benefit plan (or related trust) of the Company or
such corporation resulting from such Corporate Transaction) beneficially owns,
directly or indirectly, 20 percent or more of, respectively, the then
outstanding shares of common stock of the corporation resulting from such
Corporate Transaction or the combined voting power of the then outstanding
voting securities of such corporation except to the extent that such ownership
existed prior to the Corporate Transaction and (iii) at least a majority of the
members of the board of directors of the corporation resulting from such
Corporate Transaction were members of the Incumbent Board at the time of the
execution of the initial agreement, or of the action of the Board, providing for
such Corporate Transaction; or

          (d) Approval by the stockholders of the Company of a complete
liquidation or dissolution of the Company.

     3.   Employment Period.  The Company hereby agrees to continue the
Executive in its employ, and the Executive hereby agrees to remain in the employ
of the Company subject to the terms and conditions of this Agreement, for the
period commencing on the Effective Date and ending on the second anniversary of
such date (the "Employment Period").

     4.   Terms of Employment.

          (a)  Position and Duties.

          (i) During the Employment Period, (A) the Executive's position
(including status, offices, titles and reporting requirements, authority, duties
and responsibilities) shall be at least commensurate in all material respects
with the most 

                                       3
<PAGE>
 
significant of those held, exercised and assigned at any time during the 120-day
period immediately preceding the Effective Date and (B) the Executive's services
shall be performed at the location where the Executive was employed immediately
preceding the Effective Date or any office or location less than 35 miles from
such location.

          (ii) During the Employment Period, and excluding any periods of
vacation and sick leave to which the Executive is entitled, the Executive agrees
to devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable best efforts to perform faithfully and efficiently such
responsibilities.  During the Employment Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements or
teach at educational institutions and (C) manage personal investments, so long
as such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement.  It is expressly understood and agreed that to the extent that
any such activities have been conducted by the Executive prior to the Effective
Date, the continued conduct of such activities (or the conduct of activities
similar in nature and scope thereto) subsequent to the Effective Date shall not
thereafter be deemed to interfere with the performance of the Executive's
responsibilities to the Company.

          (b)  Compensation.

          (i) Base Salary.  During the Employment Period, the Executive shall
receive an annual base salary ("Annual Base Salary"), which shall be paid at a
monthly rate, at least equal to 12 times the highest monthly base salary paid or
payable, including any base salary which has been earned but deferred, to the
Executive by the Company and/or its affiliated companies in respect of the 60-
month period immediately preceding the month in which the Effective Date occurs.
During the Employment Period, the Annual Base Salary shall be reviewed no more
than 12 months after the last salary increase awarded to the Executive prior to
the Effective Date and thereafter at least annually.  Any increase in Annual
Base Salary shall not serve to limit or reduce any other obligation to the
Executive under this Agreement.  Annual Base Salary shall not be reduced after
any such increase and the term Annual Base Salary as utilized in this Agreement
shall refer to Annual Base Salary as so increased.  As used in this Agreement,
the term "affiliated companies" shall include any company controlled by,
controlling or under common control with the Company.

          (ii) Annual Bonus.  In addition to Annual Base Salary, the Executive
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus (the "Annual Bonus") in cash at least equal to the Executive's
highest 

                                       4
<PAGE>
 
bonus (whether in cash or Common Stock of the Company) under the Company's
annual incentive program for the last three full fiscal years prior to the
Effective Date (annualized in the event that the Executive was not employed by
the Company for the whole of such fiscal year) (the "Recent Annual Bonus"). Each
such Annual Bonus shall be paid no later than the end of the third month of the
fiscal year next following the fiscal year for which the Annual Bonus is
awarded, unless the Executive shall elect to defer the receipt of such Annual
Bonus.

          (iii) Incentive, Savings and Retirement Plans. During the Employment
Period, the Executive shall be entitled to participate in all incentive
(including any stock option or related plans, restricted stock plans or similar
plans), savings and retirement plans, practices, policies and programs
applicable generally to other peer executives of the Company and its affiliated
companies, but in no event shall such plans, practices, policies and programs
provide the Executive with incentive opportunities (measured with respect to
both regular and special incentive opportunities, to the extent, if any, that
such distinction is applicable), savings opportunities and retirement benefit
opportunities, in each case, less favorable, in the aggregate, than the most
favorable of those provided by the Company and its affiliated companies for the
Executive under such plans, practices, policies and programs as in effect at any
time during the 120-day period immediately preceding the Effective Date, or if
more favorable to the Executive, those provided generally at any time after the
Effective Date to other peer executives of the Company and its affiliated
companies.

          (iv) Welfare Benefit Plans.  During the Employment Period, the
Executive and/or the Executive's family, as the case may be, shall be eligible
to participate in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company and its affiliated
companies (including, without limitation, medical, prescription, dental,
disability, salary continuance, employee life, group life, accidental death and
travel accident insurance plans and programs) to the extent applicable generally
to other peer executives of the Company and its affiliated companies, but in no
event shall such plans, practices, policies and programs provide the Executive
with benefits which are less favorable, in the aggregate, than the most
favorable of such plans, practices, policies and programs in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, those provided generally
at any time after the Effective Date to other peer executives of the Company and
its affiliated companies.

          (v) Expenses.  During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the most favorable policies, practices and
procedures of the Company and its affiliated companies in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the 

                                       5
<PAGE>
 
Executive, as in effect generally at any time thereafter with respect to other
peer executives of the Company and its affiliated companies.

          (vi) Fringe Benefits.  During the Employment Period, the Executive
shall be entitled to fringe benefits (including without limitation, financial
planning services, payment of club dues, a car allowance or use of an automobile
and payment of related expenses, as appropriate) in accordance with the most
favorable plans, practices, programs and policies of the Company and its
affiliated companies in effect for the Executive at any time during the 120-day
period immediately preceding the Effective Date or, if more favorable to the
Executive, as in effect generally at any time thereafter with respect to other
peer executives of the Company and its affiliated companies.

          (vii)     Office and Support Staff.  During the Employment Period, the
Executive shall be entitled to an office or offices of a size and with
furnishings and other appointments, and to personal secretarial and other
assistance, at least equal to the most favorable of the foregoing provided to
the Executive by the Company and its affiliated companies at any time during the
120-day period immediately preceding the Effective Date or, if more favorable to
the Executive, as provided generally at any time thereafter with respect to
other peer executives of the Company and its affiliated companies.

          (viii) Vacation. During the Employment Period, the Executive shall be
entitled to paid vacation in accordance with the most favorable plans, policies,
programs and practices of the Company and its affiliated companies in effect for
the Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, as in effect generally at
any time thereafter with respect to other peer executives of the Company and its
affiliated companies.

          (ix) Options/SARs.  Upon the occurrence of a Change of Control
pursuant to which the Company is not the survivor (or survives only as a
subsidiary of another entity), the surviving corporation shall issue to the
Executive options and tandem stock appreciation rights ("SARs"), if applicable,
in substitution or replacement of all outstanding options or SARs previously
issued pursuant to a Company stock option plan or the Company's Stock
Appreciation Rights Plan, respectively, any such options and SARs to have terms
and conditions similar to the terms of any such original options and SARs.

     5.   Termination of Employment.

          (a) Death or Disability. The Executive's employment shall terminate
automatically upon the Executive's death during the Employment Period.  If the
Company determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition of Disability
set forth below), 

                                       6
<PAGE>
 
it may give to the Executive written notice in accordance with Section 12(b) of
this Agreement of its intention to terminate the Executive's employment. In such
event, the Executive's employment with the Company shall terminate effective 30
days after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that within the 30-day period after such receipt, the Executive
shall not have returned to full-time performance of the Executive's duties. For
purposes of this Agreement, "Disability" shall mean the absence of the Executive
from the Executive's duties with the Company on a full-time basis for 360
consecutive business days as a result of incapacity due to mental or physical
illness which is determined to be total and permanent by a physician selected by
the Company or its insurers and acceptable to the Executive or the Executive's
legal representative.

          (b) Cause.  The Company may terminate the Executive's employment
during the Employment Period for Cause.  For purposes of this Agreement, "Cause"
shall mean:

          (i) the willful and continued failure of the Executive to perform
substantially the Executive's duties with the Company or one of its affiliates
(other than any such failure resulting from incapacity due to physical or mental
illness), after a written demand for substantial performance is delivered to the
Executive by the Board or the Chief Executive Officer of the Company which
specifically identifies the manner in which the Board of Chief Executive Officer
believes that the Executive has not substantially performed the Executive's
duties, or

          (ii) the willful engaging by the Executive in illegal conduct or gross
misconduct which is materially and demonstrably injurious to the Company.

          For purposes of this provision, no act, or failure to act, on the part
of the Executive shall be considered "willful" unless it is done, or omitted to
be done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company.  Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the Chief Executive Officer or
of a senior officer of the Company or based upon the advice of counsel for the
Company shall be conclusively presumed to be done, or omitted to be done, by the
Executive in good faith and in the best interests of the Company.  The cessation
of employment of the Executive shall not be deemed to be for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Board at a meeting of the Board called and held for
such purpose (after reasonable notice is provided to the Executive and the
Executive is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the 

                                       7
<PAGE>
 
good faith opinion of the Board, the Executive is guilty of the conduct
described in subparagraph (i) or (ii) above, and specifying the particulars
thereof in detail.

          (c) Good Reason.  The Executive's employment may be terminated by the
Executive for Good Reason.  For purposes of this Agreement, "Good Reason" shall
mean:

          (i) the assignment to the Executive of any duties inconsistent in any
respect with the Executive's position (including status, offices, titles and
reporting requirements), authority, duties or responsibilities as contemplated
by Section 4(a) of this Agreement, or any other action by the Company which
results in a diminution in such position, authority, duties or responsibilities,
excluding for this purpose an isolated, insubstantial and inadvertent action not
taken in bad faith and which is remedied by the Company promptly after receipt
of notice thereof given by the Executive;

          (ii) any failure by the Company to comply with any of the provisions
of Section 4(b) of this Agreement, other than an isolated, insubstantial and
inadvertent failure not occurring in bad faith and which is remedied by the
Company promptly after receipt of notice thereof given by the Executive;

          (iii)     the Company's requiring the Executive to be based at any
office or location other than as provided in Section 4(a)(i)(B) hereof or the
Company's requiring the Executive to travel on Company business to a
substantially greater extent than required immediately prior to the Effective
Date;

          (iv) any purported termination by the Company of the Executive's
employment otherwise than as expressly permitted by this Agreement; or

          (v) any failure by the Company to comply with and satisfy Section
11(c) of this Agreement.

          For purposes of this Section 5(c), any good faith determination of
"Good Reason" made by the Executive shall be conclusive.

          (d) Notice of Termination.  Any termination by the Company for Cause,
or by the Executive for Good Reason, shall be communicated by Notice of
Termination to the other party hereto given in accordance with Section 12(b) of
the Agreement.  For purposes of this Agreement, a "Notice of Termination" means
a written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of 

                                       8
<PAGE>
 
receipt of such notice, specifies the termination date (which date shall be not
more than 30 days after the giving of such notice). The failure by the Executive
or the Company to set forth in the Notice of Termination any fact or
circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company, respectively, from asserting
such fact or circumstance in enforcing the Executive's or the Company's rights
hereunder.

          (e) Date of Termination.  "Date of Termination" shall mean:

          (i) if the Executive's employment is terminated by the Company for
Cause, or by the Executive for Good Reason, the date of receipt of the Notice of
Termination or any later date specified therein, as the case may be;

          (ii) if the Executive's employment is terminated by the Company other
than for Cause or Disability, the Date of Termination shall be the date on which
the Company notifies the Executive of such termination; and

          (iii)     if the Executive's employment is terminated by reason of
death or Disability, the Date of Termination shall be the date of death of the
Executive or the Disability Effective Date, as the case may be.

     6.   Obligations of the Company upon Termination.

          (a) Good Reason; Other than for Cause, Death or Disability.  If during
the Employment Period, the Company shall terminate the Executive's employment
other than for Cause or Disability, or the Executive shall terminate employment
for Good Reason:

          (i) The Company shall pay to the Executive in a lump sum in cash
within 30 days after the Date of Termination the aggregate of the following
amounts:

          A. the sum of (1) the Executive's Annual Base Salary through the Date
of Termination to the extent not theretofore paid, (2) the product of (x) the
higher of (I) the Recent Annual Bonus and (II) the Annual Bonus paid or payable,
including any bonus or portion thereof which has been earned but deferred (and
annualized for any fiscal year consisting of less than 12 full months or during
which the Executive was employed for less than 12 full months), for the most
recently completed fiscal year during the Employment Period, if any (such higher
amount being referred to as the "Highest Annual Bonus") and (y) a fraction, the
numerator of which is the number of days in the current fiscal year through the
Date of Termination, and the denominator of which is 365 and (3) any
compensation previously deferred by the Executive (together with any accrued
interest or earnings thereon) and any accrued vacation pay, in each case 

                                       9
<PAGE>
 
to the extent not theretofore paid (the sum of the amounts described in clauses
(1), (2) and (3) shall be hereinafter referred to as the "Accrued Obligations"),
and

          B. the amount equal to the product of (1) two and (2) the sum of (x)
the Executive's Annual Base Salary and (y) the Highest Annual Bonus, and

          C. an amount equal to the excess of (a) the actuarial equivalent of
the benefit under the Company's qualified defined benefit retirement plan (the
"Retirement Plan") (utilizing actuarial assumptions no less favorable to the
Executive than those in effect under the Company's Retirement Plan immediately
prior to the Effective Date), and any excess or supplemental retirement plan
related to the Retirement Plan in which the Executive participates (together,
the "SERP"), which the Executive would receive if the Executive's employment
continued for two year(s) after the Date of Termination assuming for this
purpose that all accrued benefits are fully vested, and assuming that the
Executive's compensation in each of the two year(s) is that required by Sections
4(b)(i) and 4(b)(ii), over (b) the actuarial equivalent of the Executive's
actual benefit (paid or payable), if any, under the Retirement Plan and the SERP
as of the Date of Termination, and

          D. an amount equal to two times the total of the Employer Matching
Contribution credited to the Executive under the Company's 401(k) Savings Plan
(the "401(k) Plan") and the Supplemental Matching Accrual credited under the
Company's Supplemental Savings Plan (the "Excess Plan") during the 12-month
period immediately preceding the month of the Executive's Date of Termination,
such amount to be grossed up so that the amount the Executive actually receives
after payment of any federal or state taxes payable thereon equals the amount
first described above;

          (ii) For two year(s) after the Executive's Date of Termination, or
such longer period as may be provided by the terms of the appropriate plan,
program, practice or policy, the Company shall continue benefits to the
Executive and/or the Executive's family equal to those which would have been
provided to them in accordance with the plans, programs, practices and policies
described in Section 4(b)(iv) of this Agreement if the Executive's employment
had not been terminated; provided, however, that with respect to any of such
plans, programs, practices or policies requiring an employee contribution, the
Executive shall continue to pay the monthly employee contribution for same, and
provided further, that if the Executive becomes reemployed by another employer
and is eligible to receive medical or other welfare benefits under another
employer provided plan, the medical and other welfare benefits described herein
shall be secondary to those provided under such other plan during such
applicable period of eligibility;

                                       10
<PAGE>
 
          (iii) The Company shall, at its sole expense as incurred, provide the
Executive with outplacement services, the scope and provider of which shall be
selected by the Executive in his sole discretion;

          (iv) With respect to all options to purchase Common Stock held by the
Executive pursuant to a Company stock option plan on or prior to the Date of
Termination, irrespective of whether such options are then exercisable, the
Executive shall have the right, during the 60-day period after the Date of
Termination, to elect to surrender all or part of such options in exchange for a
cash payment by the Company to the Executive in an amount equal the number of
shares of Common Stock subject to the Executive's option multiplied by the
difference between (x) and (y) where (y) equals the purchase price per share
covered by the option and (x) equals the highest reported sale price of a share
of Common Stock in any transaction reported on the New York Stock Exchange
during the 60-day period prior to and including the Executive's Date of
Termination; and with respect to all SARs held by the Executive granted under
the Company's Stock Appreciation Rights Plan on or prior to the Date of
Termination, irrespective of whether such SARs are then exercisable, the
Executive shall have the right, during the 60-day period after the Date of
Termination, to elect to surrender all or part of such SARs in exchange for a
cash payment by the Company to the Executive in an amount equal to an amount
equal to the number of SARs held by the Executive multiplied by the difference
between (x) and (y) where (y) equals the fair market value of such SARs the date
on which awarded and (x) equals the price set forth above.  Such cash payments
shall be made within 30 days after the date of the Executive's election;
provided, however, that if the Executive's Date of Termination is within six
months after the date of grant of a particular option or SAR held by the
Executive and the Executive is subject to Section 16(b) of the Securities
Exchange Act of 1934, any cash payments related thereto shall be made on the
date which is six months and one day after the date of grant of such option or
SAR.  Notwithstanding the foregoing, if any right granted pursuant to the
foregoing would make a Change of Control transaction ineligible for pooling of
interests accounting treatment under APB No. 16 that but for this Section
6(a)(iv) would otherwise be eligible for such accounting treatment, the
Executive shall receive shares of Common Stock with a Fair Market Value equal to
the cash that would otherwise be payable hereunder in substitution for the cash,
provided that any such shares of Common Stock so granted to the Executive shall
be registered under the Securities Act of 1933; any options or SARs outstanding
as of the Date of Termination and not then exercisable shall become fully
exercisable as of the Executive's Date of Termination, and to the extent the
Executive does not elect to surrender same for a cash payment (or the equivalent
number of shares of Common Stock) as provided above, such options and SARs shall
remain exercisable for seven months after the Executive's Date of Termination or
until the stated expiration of the stated term thereof, whichever is shorter;
restrictions applicable to any shares of Common Stock granted to the Executive
under the 

                                       11
<PAGE>
 
Company's Restricted Stock Incentive Plan shall lapse, as of the date of the
Executive's Date of Termination;

          (v) All country club memberships, luncheon clubs and other memberships
which the Company was providing for the Executive's use at the time of Notice of
Termination is given shall, to the extent possible, be transferred and assigned
to the Executive at no cost to the Executive (other than income taxes owed), the
cost of transfer, if any, to be borne by the Company;

          (vi) The Company shall either transfer to the Executive ownership and
title to the Executive's Company car at no cost to the Executive (other than
income taxes owed) or, if the Executive receives a monthly car allowance in lieu
of a Company car, pay the Executive a lump sum in cash within 30 days after the
Executive's Date of Termination an amount equal to two times the Executive's
annual car allowance;

          (vii) All benefits under the Company's Retirement Plan, the SERP, and
the 401(k) Plan and the Excess Plan, and any other similar plans, not already
vested shall be 100% vested, to the extent such vesting is permitted under the
Code (as defined below); and

          (viii) To the extent not theretofore paid or provided, the Company
shall timely pay or provide to the Executive any other amounts or benefits
required to be paid or provided or which the Executive is eligible to receive
under any plan, program, policy or practice or contract or agreement of the
Company and its affiliated companies (such other amounts and benefits shall be
hereinafter referred to as the "Other Benefits").

          (b) Death.  If the Executive's employment is terminated by reason of
the Executive's death during the Employment Period, this Agreement shall
terminate without further obligations to the Executive's legal representatives
under this Agreement, other than for payment of Accrued Obligations and the
timely payment or provision of Other Benefits.  Accrued Obligations shall be
paid to the Executive's estate or beneficiaries, as applicable, in a lump sum in
cash within 30 days after the Date of Termination.  With respect to the
provision of Other Benefits, the term Other Benefits as utilized in this Section
6(b) shall include, without limitation, and the Executive's estate and/or
beneficiaries shall be entitled to receive, benefits equal to the benefits
provided by the Company and affiliated companies to the estates and
beneficiaries of peer executives of the Company and such affiliated companies
under such plans, programs, practices and policies relating to death benefits,
if any, in effect on the date of the Executive's death.

          (c) Disability.  If the Executive's employment is terminated by reason
of the Executive's Disability during the Employment Period, this Agreement shall

                                       12
<PAGE>
 
terminate without further obligations to the Executive, other than for payment
of Accrued Obligations and the timely payment or provision of Other Benefits.
Accrued Obligations shall be paid to the Executive in a lump sum in cash within
30 days after the Date of Termination.  With respect to the provision of Other
Benefits, the term Other Benefits as utilized in this Section 6(c) shall
include, without limitation, and the Executive shall be entitled after the
Disability Effective Date to receive, disability and other benefits equal to
those generally provided by the Company and its affiliated companies to disabled
peer executives and/or their families in accordance with such plans programs,
practices and policies relating to disability, if any, in effect generally with
respect to other peer executives and their families at any time of the
Disability.

          (d) Cause; Other than for Good Reason.  If the Executive's employment
shall be terminated for Cause during the Employment Period, this Agreement shall
terminate without further obligations to the Executive other than the obligation
to pay to the Executive (x) his Annual Base Salary through the Date of
Termination, (y) the amount of any compensation previously deferred by the
Executive, and (z) Other Benefits, in each case to the extent theretofore
unpaid.  If the Executive voluntarily terminates employment during the
Employment Period, excluding a termination for Good Reason, this Agreement shall
terminate without further obligations to the Executive, other than for Accrued
Obligations and the timely payment or provision of Other Benefits.  In such
case, all Accrued Obligations shall be paid to the Executive in a lump sum in
cash within 30 days after the Date of Termination.

     7.   Non-exclusivity of Rights.  Nothing in this Agreement shall prevent or
limit the Executive's continuing or future participation in any plan, program,
policy or practice provided by the Company or any of its affiliated companies
and for which the Executive may qualify, nor, subject to Section 12(f), shall
anything herein limit or otherwise affect such rights as the Executive may have
under any contract or agreement with the Company or any of its affiliated
companies.  Amounts which are vested benefits or which the Executive is
otherwise entitled to receive under any plan, policy, practice or program of or
any contract or agreement with the Company or any of its affiliated companies at
or subsequent to the Date of Termination shall be payable in accordance with
such plan, policy, practice or program or contract or agreement except as
explicitly modified by this Agreement.

     8.   Full Settlement.  The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others.  In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and such amounts
shall not be reduced whether or not the Executive obtains 

                                       13
<PAGE>
 
other employment. The Company agrees to pay as incurred, to the full extent
permitted by law, all legal fees and expense which the Executive may reasonably
incur as a result of any contest (regardless of the outcome thereof) by the
Company, the Executive or others of the validity or enforceability of, or
liability under, any provision of this Agreement or any guarantee of performance
thereto (including as a result of any contest by the Executive about the amount
of any payment pursuant to this Agreement), plus in each case interest on any
delayed payment at the applicable Federal rate provided for in Section
7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended (the "Code").

     9.   Certain Additional Payments by the Company.

          (a) Anything in this Agreement to the contrary notwithstanding and
except as set forth below, in the event it shall be determined that any payment
or distribution by the Company to or for the benefit of the Executive (whether
paid or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise, but determined without regard to any additional payments
required under this Section 9) (a "Payment") would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Executive with respect to such excise tax (such excise tax, together with
any such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including without limitation, any income taxes (and any interest
and penalties imposed with respect thereto) and Excise Tax imposed upon the
Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal
to the Excise Tax imposed upon the Payments.  Notwithstanding the foregoing
provisions of this Section 9(a), if it shall be determined that the Executive is
entitled to a Gross-Up Payment, but that the Executive, after taking into
account the Payments and the Gross-Up Payment, would not receive a net after-tax
benefit of at least $50,000 (taking into account both income taxes and any
Excise Tax) as compared to the net after-tax proceeds to the Executive resulting
from an elimination of the Gross-Up Payment and a reduction of the Payments, in
the aggregate, to an amount (the "Reduced Amount") such that the receipt of
Payments would not give rise to any Excise Tax, then no Gross-Up Payment shall
be made to the Executive and the Payments, in the aggregate, shall be reduced to
the Reduced Amount.

          (b) Subject to the provisions of Section 9(c), all determinations
required to be made under this Section 9, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination shall be made by Arthur
Andersen LLP or, as provided below, such other certified public accounting firm
as may be designated by the Executive (the "Accounting Firm") which shall
provide detailed supporting calculations both to the 

                                       14
<PAGE>
 
Company and the Executive within 15 business days after the receipt of notice
from the Executive that there has been a Payment, or such earlier time as is
requested by the Company. In the event that the Accounting Firm is serving as
accountant or auditor for the individual, entity or group effecting the Change
of Control, the Executive shall appoint another nationally recognized accounting
firm to make the determinations required hereunder (which accounting firm shall
then be referred to as the Accounting Firm hereunder). All fees and expenses of
the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment,
as determined pursuant to this Section 9, shall be paid by the Company to the
Executive within five days after the receipt of the Accounting Firm's
determination. Any determination by the Accounting Firm shall be binding upon
the Company and the Executive. As a result of the uncertainty in the application
of Section 4999 of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Gross-Up Payments which will not
have been made by the Company should have been made ("Underpayment"), consistent
with the calculations required to be made hereunder. In the event that the
Company exhausts its remedies pursuant to Section 9(c) and the Executive
thereafter is required to make a payment of any Excise Tax, the Accounting Firm
shall determine the amount of the Underpayment that has occurred and any such
Underpayment shall be promptly paid by the Company to or for the benefit of the
Executive.

          (c) The Executive shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the payment by
the Company of the Gross-Up Payment.  Such notification shall be given as soon
as practicable, but no later than ten business days after the Executive is
informed in writing of such claim, and shall apprise the Company of the nature
of such claim and the date on which such claim is requested to be paid.  The
Executive shall not pay such claim prior to the expiration of the 30-day period
following the date on which he gives such notice to the Company (or such shorter
period ending on the date that any payment of taxes with respect to such claim
is due).  If the Company notifies the Executive in writing prior to the
expiration of such period that it desires to contest such claim the Executive
shall:

          (i) give the Company any information reasonably requested by the
Company relating to such claim,

          (ii) take such action in connection with contesting such claim as the
Company shall reasonably request in writing from time to time, including without
limitation, accepting legal representation with respect to such claim by an
attorney reasonably selected by the Company,

          (iii) cooperate with the Company in good faith in order effectively to
contest such claim, and

                                       15
<PAGE>
 
          (iv) permit the Company to participate in any proceedings relating to
such claims; provided, however, that the Company shall bear and pay directly all
costs and expenses (including additional interest and penalties) incurred in
connection with such costs and shall indemnify and hold the Executive harmless,
on an after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses.  Without limitation on the foregoing provisions
of this Section 9(c), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct the Executive to pay the tax claimed and sue for a refund or contest the
claim in any permissible manner, and the Executive agrees to prosecute such
contest to determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further provided that any extension of the statute of limitations relating
to payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount.  Furthermore, the Company's control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issues raised by the Internal Revenue Service or any other taxing
authority.

          (d) If, after the receipt by the Executive of an amount advanced by
the Company pursuant to Section 9(c), the Executive becomes entitled to receive
any refund with respect to such claim, the Executive shall (subject to the
Company's complying with the requirements of Section 9(c)) promptly pay to the
Company the amount of such refund (together with any interest paid or credited
thereon after taxes applicable thereto).  If, after the receipt by the Executive
of an amount advanced by the Company pursuant to Section 9(c), a determination
is made that the Executive shall not be entitled to any refund with respect to
such claim and the Company does not notify the Executive in writing of its
intent to contest such denial of refund prior to the expiration of 30 days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the amount of such advance shall offset, to the extent
thereof, the amount of Gross-Up Payment required to be paid.

     10.  Confidential Information.  The Executive shall hold in a fiduciary
capacity for the benefit of the Company all secret or confidential information,
knowledge or data 

                                       16
<PAGE>
 
relating to the Company or any of its affiliated companies, and their respective
businesses, which shall have been obtained by the Executive during the
Executive's employment by the Company or any of its affiliated companies,
provided that it shall not apply to information which is or shall become public
knowledge (other than by acts by the Executive or representatives of the
Executive in violation of this Agreement), information that is developed by the
Executive independently of such information, or knowledge or data or information
that is disclosed to the Executive by a third party under no obligation of
confidentiality to the Company. After termination of the Executive's employment
with the Company, the Executive shall not, without the prior written consent of
the Company or as may otherwise be required by law or legal process, communicate
or divulge any such information, knowledge or data to anyone other than the
Company and those designated by it. In no event shall an asserted violation of
the provisions of this Section 10 constitute a basis for deferring or
withholding any amounts otherwise payable to the Executive under this Agreement.

     11.  Successors.

          (a) This Agreement is personal to the Executive and without the prior
written consent of the Company shall not be assignable by the Executive
otherwise than by will or the laws of descent and distribution.  This Agreement
shall inure to the benefit of and be enforceable by the Executive's legal
representatives.

          (b) This Agreement shall inure to the benefit of and be binding upon
the Company and its successors and assigns.

          (c) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

     12.  Miscellaneous.

          (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Texas, without reference to principles of conflict
of laws.  The captions of this Agreement are not part of the provisions hereof
and shall have no force or effect.  This Agreement may not be amended or
modified otherwise than by a written agreement executed by the parties hereto or
their respective successors and legal representatives.

compliance with any provision of this Agreement or the failure to assert any

the Effective Date this Agreement shall supersede any other agreement between
the parties with respect to the subject matter hereof.

                          CHANGE OF CONTROL AGREEMENT

     This Change of Control Agreement by and between Weatherford Enterra, Inc.,
a Delaware corporation (the "Company"), and Steven C. Grant (the "Executive"),
dated as of October 5, 1995.

                                   RECITALS:

     A. The Board of Directors of the Company (the "Board") has previously
determined that it is in the best interests of the Company and its stockholders
to assure that the Company will have the continued dedication of the Executive,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Company. The Board believes it is imperative to diminish
the inevitable distraction of the Executive by virtue of the personal
uncertainties and risks created by a pending or threatened Change of Control and
to encourage the Executive's full attention and dedication to the Company
currently and in the event of any threatened or pending Change of Control, and
to provide the Executive with compensation and benefits arrangements upon a
Change of Control which ensure that the compensation and benefits expectations
of the Executive, which are competitive with those of executives at other
corporations, will be satisfied.

     B. To accomplish these objectives, the Board has caused the Company to
enter into this Agreement.

     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1. Certain Definitions.

          (a) The "Effective Date" shall mean the first date during the Change
of Control Period (as defined in Section 1(b)) on which a Change of Control (as
defined in Section 2) occurs.  Anything in this Agreement to the contrary
notwithstanding, if a Change of Control occurs and if the Executive's employment
with the Company is terminated prior to the date on which the Change of Control
occurs, and if it is reasonably demonstrated by the Executive that such
termination of employment (i) was at the request of a third party who has taken
steps reasonably calculated to effect a Change of Control or (ii) otherwise
arose in connection with or anticipation of a Change of Control, then for all
purposes of this Agreement the "Effective Date" shall mean the date immediately
prior to the date of such termination of employment.

          (b) The "Change of Control Period" shall mean the period commencing on
the date hereof and ending on the first anniversary of the date hereof;
provided, 

                                       2
<PAGE>
 
however, that commencing on the date one year after the date hereof, and on each
annual anniversary of such date (such date and each annual anniversary thereof
shall be hereinafter referred to as the "Renewal Date"), unless previously
terminated, the Change of Control Period shall be automatically extended so as
to terminate one year(s) after such Renewal Date, unless at least 60 days prior
to the Renewal Date the Company shall give notice to the Executive that the
Change of Control Period shall not be so extended.

     2. Change of Control. For the purpose of this Agreement, a "Change of
Control" shall mean:

          (a) The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however that for purposes of this subsection (a), the following
acquisitions shall not constitute a Change of Control:

          (i) any acquisition directly from the Company,

          (ii) any acquisition by the Company,

          (iii) any acquisition by any employee benefit plan (or related
trust) sponsored or maintained by the Company or any corporation controlled by
the Company, or

          (iv) any acquisition by any corporation pursuant to a transaction
which complies with clauses (i), (ii) and (iii) of subsection (c) of this
Section 2; or

         (b) Individuals, who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual was a member of the Incumbent Board, but excluding, for this purpose,
any such individual whose initial assumption of office occurs as a result of an
actual or threatened election contest with respect to the election or removal of
directors or other actual or threatened solicitation of proxies or consents by
or on behalf of a Person other than the Board; or

                                       2
<PAGE>
 
         (c) Consummation of a reorganization, merger or consolidation or sale
or other disposition of all or substantially all of the assets of the Company (a
"Corporate Transaction") in each case, unless, following such Corporate
Transaction, (i) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities immediately prior to such
Corporate Transaction beneficially own, directly or indirectly, more than 60
percent of, respectively, the then outstanding shares of common stock and the
combined voting power of the then outstanding voting securities entitled to vote
generally in the election of directors, as the case may be, of the corporation
resulting from such Corporate Transaction (including, without limitation, a
corporation which as a result of such transaction owns the Company or all or
substantially all of the Company's assets either directly or through one or more
subsidiaries) in substantially the same proportions as their ownership,
immediately prior to such Corporate Transaction, of the Outstanding Company
Common Stock and the Outstanding Company Voting Securities, as the case may be,
(ii) no Person (excluding any corporation resulting from such Corporate
Transaction or any employee benefit plan (or related trust) of the Company or
such corporation resulting from such Corporate Transaction) beneficially owns,
directly or indirectly, 20 percent or more of, respectively, the then
outstanding shares of common stock of the corporation resulting from such
Corporate Transaction or the combined voting power of the then outstanding
voting securities of such corporation except to the extent that such ownership
existed prior to the Corporate Transaction and (iii) at least a majority of the
members of the board of directors of the corporation resulting from such
Corporate Transaction were members of the Incumbent Board at the time of the
execution of the initial agreement, or of the action of the Board, providing for
such Corporate Transaction; or

         (d) Approval by the stockholders of the Company of a complete
liquidation or dissolution of the Company.

     3.  Employment Period.  The Company hereby agrees to continue the Executive
in its employ, and the Executive hereby agrees to remain in the employ of the
Company subject to the terms and conditions of this Agreement, for the period
commencing on the Effective Date and ending on the first anniversary of such
date (the "Employment Period").

     4.  Terms of Employment.

         (a)   Position and Duties.

          (i) During the Employment Period, (A) the Executive's position
(including status, offices, titles and reporting requirements, authority, duties
and responsibilities) shall be at least commensurate in all material respects
with the most

                                       3
<PAGE>
 
significant of those held, exercised and assigned at any time during the 120-day
period immediately preceding the Effective Date and (B) the Executive's services
shall be performed at the location where the Executive was employed immediately
preceding the Effective Date or any office or location less than 35 miles from
such location.

          (ii) During the Employment Period, and excluding any periods of
vacation and sick leave to which the Executive is entitled, the Executive agrees
to devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable best efforts to perform faithfully and efficiently such
responsibilities.  During the Employment Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements or
teach at educational institutions and (C) manage personal investments, so long
as such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement.  It is expressly understood and agreed that to the extent that
any such activities have been conducted by the Executive prior to the Effective
Date, the continued conduct of such activities (or the conduct of activities
similar in nature and scope thereto) subsequent to the Effective Date shall not
thereafter be deemed to interfere with the performance of the Executive's
responsibilities to the Company.

         (b)   Compensation.

          (i) Base Salary.  During the Employment Period, the Executive shall
receive an annual base salary ("Annual Base Salary"), which shall be paid at a
monthly rate, at least equal to 12 times the highest monthly base salary paid or
payable, including any base salary which has been earned but deferred, to the
Executive by the Company and/or its affiliated companies in respect of the 60-
month period immediately preceding the month in which the Effective Date occurs.
During the Employment Period, the Annual Base Salary shall be reviewed no more
than 12 months after the last salary increase awarded to the Executive prior to
the Effective Date and thereafter at least annually.  Any increase in Annual
Base Salary shall not serve to limit or reduce any other obligation to the
Executive under this Agreement.  Annual Base Salary shall not be reduced after
any such increase and the term Annual Base Salary as utilized in this Agreement
shall refer to Annual Base Salary as so increased.  As used in this Agreement,
the term "affiliated companies" shall include any company controlled by,
controlling or under common control with the Company.

          (ii) Annual Bonus.  In addition to Annual Base Salary, the Executive
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus (the "Annual Bonus") in cash at least equal to the Executive's
highest

                                       4
<PAGE>
 
bonus (whether in cash or Common Stock of the Company) under the Company's
annual incentive program for the last three full fiscal years prior to the
Effective Date (annualized in the event that the Executive was not employed by
the Company for the whole of such fiscal year) (the "Recent Annual Bonus").
Each such Annual Bonus shall be paid no later than the end of the third month of
the fiscal year next following the fiscal year for which the Annual Bonus is
awarded, unless the Executive shall elect to defer the receipt of such Annual
Bonus.

          (iii) Incentive, Savings and Retirement Plans.  During the
Employment Period, the Executive shall be entitled to participate in all
incentive (including any stock option or related plans, restricted stock plans
or similar plans), savings and retirement plans, practices, policies and
programs applicable generally to other peer executives of the Company and its
affiliated companies, but in no event shall such plans, practices, policies and
programs provide the Executive with incentive opportunities (measured with
respect to both regular and special incentive opportunities, to the extent, if
any, that such distinction is applicable), savings opportunities and retirement
benefit opportunities, in each case, less favorable, in the aggregate, than the
most favorable of those provided by the Company and its affiliated companies for
the Executive under such plans, practices, policies and programs as in effect at
any time during the 120-day period immediately preceding the Effective Date, or
if more favorable to the Executive, those provided generally at any time after
the Effective Date to other peer executives of the Company and its affiliated
companies.

          (iv) Welfare Benefit Plans.  During the Employment Period, the
Executive and/or the Executive's family, as the case may be, shall be eligible
to participate in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company and its affiliated
companies (including, without limitation, medical, prescription, dental,
disability, salary continuance, employee life, group life, accidental death and
travel accident insurance plans and programs) to the extent applicable generally
to other peer executives of the Company and its affiliated companies, but in no
event shall such plans, practices, policies and programs provide the Executive
with benefits which are less favorable, in the aggregate, than the most
favorable of such plans, practices, policies and programs in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, those provided generally
at any time after the Effective Date to other peer executives of the Company and
its affiliated companies.

          (v) Expenses.  During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the most favorable policies, practices and
procedures of the Company and its affiliated companies in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the

                                       5
<PAGE>
 
Executive, as in effect generally at any time thereafter with respect to other
peer executives of the Company and its affiliated companies.

          (vi) Fringe Benefits.  During the Employment Period, the Executive
shall be entitled to fringe benefits (including without limitation, financial
planning services, payment of club dues, a car allowance or use of an automobile
and payment of related expenses, as appropriate) in accordance with the most
favorable plans, practices, programs and policies of the Company and its
affiliated companies in effect for the Executive at any time during the 120-day
period immediately preceding the Effective Date or, if more favorable to the
Executive, as in effect generally at any time thereafter with respect to other
peer executives of the Company and its affiliated companies.

          (vii) Office and Support Staff.  During the Employment Period, the
Executive shall be entitled to an office or offices of a size and with
furnishings and other appointments, and to personal secretarial and other
assistance, at least equal to the most favorable of the foregoing provided to
the Executive by the Company and its affiliated companies at any time during the
120-day period immediately preceding the Effective Date or, if more favorable to
the Executive, as provided generally at any time thereafter with respect to
other peer executives of the Company and its affiliated companies.

          (viii) Vacation. During the Employment Period, the Executive shall be
entitled to paid vacation in accordance with the most favorable plans, policies,
programs and practices of the Company and its affiliated companies in effect for
the Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, as in effect generally at
any time thereafter with respect to other peer executives of the Company and its
affiliated companies.

          (ix) Options/SARs.  Upon the occurrence of a Change of Control
pursuant to which the Company is not the survivor (or survives only as a
subsidiary of another entity), the surviving corporation shall issue to the
Executive options and tandem stock appreciation rights ("SARs"), if applicable,
in substitution or replacement of all outstanding options or SARs previously
issued pursuant to a Company stock option plan or the Company's Stock
Appreciation Rights Plan, respectively, any such options and SARs to have terms
and conditions similar to the terms of any such original options and SARs.

     5.  Termination of Employment.

         (a) Death or Disability. The Executive's employment shall terminate
automatically upon the Executive's death during the Employment Period.  If the
Company determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition of Disability
set forth below),

                                       6
<PAGE>
 
it may give to the Executive written notice in accordance with Section 12(b) of
this Agreement of its intention to terminate the Executive's employment.  In
such event, the Executive's employment with the Company shall terminate
effective 30 days after receipt of such notice by the Executive (the "Disability
Effective Date"), provided that within the 30-day period after such receipt, the
Executive shall not have returned to full-time performance of the Executive's
duties.  For purposes of this Agreement, "Disability" shall mean the absence of
the Executive from the Executive's duties with the Company on a full-time basis
for 360 consecutive business days as a result of incapacity due to mental or
physical illness which is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the Executive or the
Executive's legal representative.

         (b) Cause.  The Company may terminate the Executive's employment during
the Employment Period for Cause.  For purposes of this Agreement, "Cause" shall
mean:

          (i) the willful and continued failure of the Executive to perform
substantially the Executive's duties with the Company or one of its affiliates
(other than any such failure resulting from incapacity due to physical or mental
illness), after a written demand for substantial performance is delivered to the
Executive by the Board or the Chief Executive Officer of the Company which
specifically identifies the manner in which the Board of Chief Executive Officer
believes that the Executive has not substantially performed the Executive's
duties, or

          (ii) the willful engaging by the Executive in illegal conduct or gross
misconduct which is materially and demonstrably injurious to the Company.

          For purposes of this provision, no act, or failure to act, on the part
of the Executive shall be considered "willful" unless it is done, or omitted to
be done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company.  Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the Chief Executive Officer or
of a senior officer of the Company or based upon the advice of counsel for the
Company shall be conclusively presumed to be done, or omitted to be done, by the
Executive in good faith and in the best interests of the Company.  The cessation
of employment of the Executive shall not be deemed to be for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Board at a meeting of the Board called and held for
such purpose (after reasonable notice is provided to the Executive and the
Executive is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the

                                       7
<PAGE>
 
good faith opinion of the Board, the Executive is guilty of the conduct
described in subparagraph (i) or (ii) above, and specifying the particulars
thereof in detail.

         (c) Good Reason.  The Executive's employment may be terminated by the
Executive for Good Reason.  For purposes of this Agreement, "Good Reason" shall
mean:

          (i) the assignment to the Executive of any duties inconsistent in any
respect with the Executive's position (including status, offices, titles and
reporting requirements), authority, duties or responsibilities as contemplated
by Section 4(a) of this Agreement, or any other action by the Company which
results in a diminution in such position, authority, duties or responsibilities,
excluding for this purpose an isolated, insubstantial and inadvertent action not
taken in bad faith and which is remedied by the Company promptly after receipt
of notice thereof given by the Executive;

          (ii) any failure by the Company to comply with any of the provisions
of Section 4(b) of this Agreement, other than an isolated, insubstantial and
inadvertent failure not occurring in bad faith and which is remedied by the
Company promptly after receipt of notice thereof given by the Executive;

          (iii) the Company's requiring the Executive to be based at any
office or location other than as provided in Section 4(a)(i)(B) hereof or the
Company's requiring the Executive to travel on Company business to a
substantially greater extent than required immediately prior to the Effective
Date;

          (iv) any purported termination by the Company of the Executive's
employment otherwise than as expressly permitted by this Agreement; or

          (v) any failure by the Company to comply with and satisfy Section
11(c) of this Agreement.

          For purposes of this Section 5(c), any good faith determination of
"Good Reason" made by the Executive shall be conclusive.

         (d) Notice of Termination.  Any termination by the Company for Cause,
or by the Executive for Good Reason, shall be communicated by Notice of
Termination to the other party hereto given in accordance with Section 12(b) of
the Agreement.  For purposes of this Agreement, a "Notice of Termination" means
a written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of

                                       8
<PAGE>
 
receipt of such notice, specifies the termination date (which date shall be not
more than 30 days after the giving of such notice).  The failure by the
Executive or the Company to set forth in the Notice of Termination any fact or
circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company, respectively, from asserting
such fact or circumstance in enforcing the Executive's or the Company's rights
hereunder.

         (e) Date of Termination.  "Date of Termination" shall mean:

          (i) if the Executive's employment is terminated by the Company for
Cause, or by the Executive for Good Reason, the date of receipt of the Notice of
Termination or any later date specified therein, as the case may be;

          (ii) if the Executive's employment is terminated by the Company other
than for Cause or Disability, the Date of Termination shall be the date on which
the Company notifies the Executive of such termination; and

          (iii) if the Executive's employment is terminated by reason of death
or Disability, the Date of Termination shall be the date of death of the
Executive or the Disability Effective Date, as the case may be.

     6.  Obligations of the Company upon Termination.

         (a) Good Reason; Other than for Cause, Death or Disability.  If during
the Employment Period, the Company shall terminate the Executive's employment
other than for Cause or Disability, or the Executive shall terminate employment
for Good Reason:

          (i) The Company shall pay to the Executive in a lump sum in cash
within 30 days after the Date of Termination the aggregate of the following
amounts:

          A. the sum of (1) the Executive's Annual Base Salary through the Date
of Termination to the extent not theretofore paid, (2) the product of (x) the
higher of (I) the Recent Annual Bonus and (II) the Annual Bonus paid or payable,
including any bonus or portion thereof which has been earned but deferred (and
annualized for any fiscal year consisting of less than 12 full months or during
which the Executive was employed for less than 12 full months), for the most
recently completed fiscal year during the Employment Period, if any (such higher
amount being referred to as the "Highest Annual Bonus") and (y) a fraction, the
numerator of which is the number of days in the current fiscal year through the
Date of Termination, and the denominator of which is 365 and (3) any
compensation previously deferred by the Executive (together with any accrued
interest or earnings thereon) and any accrued vacation pay, in each case

                                       9
<PAGE>
 
to the extent not theretofore paid (the sum of the amounts described in clauses
(1), (2) and (3) shall be hereinafter referred to as the "Accrued Obligations"),
and

          B. the amount equal to the product of (1) one and (2) the sum of (x)
the Executive's Annual Base Salary and (y) the Highest Annual Bonus, and

          C. an amount equal to the excess of (a) the actuarial equivalent of
the benefit under the Company's qualified defined benefit retirement plan (the
"Retirement Plan") (utilizing actuarial assumptions no less favorable to the
Executive than those in effect under the Company's Retirement Plan immediately
prior to the Effective Date), and any excess or supplemental retirement plan
related to the Retirement Plan in which the Executive participates (together,
the "SERP"), which the Executive would receive if the Executive's employment
continued for one year(s) after the Date of Termination assuming for this
purpose that all accrued benefits are fully vested, and assuming that the
Executive's compensation in each of the one year(s) is that required by Sections
4(b)(i) and 4(b)(ii), over (b) the actuarial equivalent of the Executive's
actual benefit (paid or payable), if any, under the Retirement Plan and the SERP
as of the Date of Termination, and

          D. an amount equal to one times the total of the Employer Matching
Contribution credited to the Executive under the Company's 401(k) Savings Plan
(the "401(k) Plan") and the Supplemental Matching Accrual credited under the
Company's Supplemental Savings Plan (the "Excess Plan") during the 12-month
period immediately preceding the month of the Executive's Date of Termination,
such amount to be grossed up so that the amount the Executive actually receives
after payment of any federal or state taxes payable thereon equals the amount
first described above;

          (ii) For ____ year(s) after the Executive's Date of Termination, or
such longer period as may be provided by the terms of the appropriate plan,
program, practice or policy, the Company shall continue benefits to the
Executive and/or the Executive's family equal to those which would have been
provided to them in accordance with the plans, programs, practices and policies
described in Section 4(b)(iv) of this Agreement if the Executive's employment
had not been terminated; provided, however, that with respect to any of such
plans, programs, practices or policies requiring an employee contribution, the
Executive shall continue to pay the monthly employee contribution for same, and
provided further, that if the Executive becomes reemployed by another employer
and is eligible to receive medical or other welfare benefits under another
employer provided plan, the medical and other welfare benefits described herein
shall be secondary to those provided under such other plan during such
applicable period of eligibility;

                                      10
<PAGE>
 
          (iii) The Company shall, at its sole expense as incurred, provide the
Executive with outplacement services, the scope and provider of which shall be
selected by the Executive in his sole discretion;

          (iv) With respect to all options to purchase Common Stock held by the
Executive pursuant to a Company stock option plan on or prior to the Date of
Termination, irrespective of whether such options are then exercisable, the
Executive shall have the right, during the 60-day period after the Date of
Termination, to elect to surrender all or part of such options in exchange for a
cash payment by the Company to the Executive in an amount equal the number of
shares of Common Stock subject to the Executive's option multiplied by the
difference between (x) and (y) where (y) equals the purchase price per share
covered by the option and (x) equals the highest reported sale price of a share
of Common Stock in any transaction reported on the New York Stock Exchange
during the 60-day period prior to and including the Executive's Date of
Termination; and with respect to all SARs held by the Executive granted under
the Company's Stock Appreciation Rights Plan on or prior to the Date of
Termination, irrespective of whether such SARs are then exercisable, the
Executive shall have the right, during the 60-day period after the Date of
Termination, to elect to surrender all or part of such SARs in exchange for a
cash payment by the Company to the Executive in an amount equal to an amount
equal to the number of SARs held by the Executive multiplied by the difference
between (x) and (y) where (y) equals the fair market value of such SARs the date
on which awarded and (x) equals the price set forth above.  Such cash payments
shall be made within 30 days after the date of the Executive's election;
provided, however, that if the Executive's Date of Termination is within six
months after the date of grant of a particular option or SAR held by the
Executive and the Executive is subject to Section 16(b) of the Securities
Exchange Act of 1934, any cash payments related thereto shall be made on the
date which is six months and one day after the date of grant of such option or
SAR.  Notwithstanding the foregoing, if any right granted pursuant to the
foregoing would make a Change of Control transaction ineligible for pooling of
interests accounting treatment under APB No. 16 that but for this Section
6(a)(iv) would otherwise be eligible for such accounting treatment, the
Executive shall receive shares of Common Stock with a Fair Market Value equal to
the cash that would otherwise be payable hereunder in substitution for the cash,
provided that any such shares of Common Stock so granted to the Executive shall
be registered under the Securities Act of 1933; any options or SARs outstanding
as of the Date of Termination and not then exercisable shall become fully
exercisable as of the Executive's Date of Termination, and to the extent the
Executive does not elect to surrender same for a cash payment (or the equivalent
number of shares of Common Stock) as provided above, such options and SARs shall
remain exercisable for seven months after the Executive's Date of Termination or
until the stated expiration of the stated term thereof, whichever is shorter;
restrictions applicable to any shares of Common Stock granted to the Executive
under the

                                      11
<PAGE>
 
Company's Restricted Stock Incentive Plan shall lapse, as of the date of the
Executive's Date of Termination;

          (v) All country club memberships, luncheon clubs and other memberships
which the Company was providing for the Executive's use at the time of Notice of
Termination is given shall, to the extent possible, be transferred and assigned
to the Executive at no cost to the Executive (other than income taxes owed), the
cost of transfer, if any, to be borne by the Company;

          (vi) The Company shall either transfer to the Executive ownership and
title to the Executive's Company car at no cost to the Executive (other than
income taxes owed) or, if the Executive receives a monthly car allowance in lieu
of a Company car, pay the Executive a lump sum in cash within 30 days after the
Executive's Date of Termination an amount equal to one times the Executive's
annual car allowance;

          (vii) All benefits under the Company's Retirement Plan, the SERP, and
the 401(k) Plan and the Excess Plan, and any other similar plans, not already
vested shall be 100% vested, to the extent such vesting is permitted under the
Code (as defined below); and

          (viii) To the extent not theretofore paid or provided, the Company
shall timely pay or provide to the Executive any other amounts or benefits
required to be paid or provided or which the Executive is eligible to receive
under any plan, program, policy or practice or contract or agreement of the
Company and its affiliated companies (such other amounts and benefits shall be
hereinafter referred to as the "Other Benefits").

         (b) Death.  If the Executive's employment is terminated by reason of
the Executive's death during the Employment Period, this Agreement shall
terminate without further obligations to the Executive's legal representatives
under this Agreement, other than for payment of Accrued Obligations and the
timely payment or provision of Other Benefits.  Accrued Obligations shall be
paid to the Executive's estate or beneficiaries, as applicable, in a lump sum in
cash within 30 days after the Date of Termination.  With respect to the
provision of Other Benefits, the term Other Benefits as utilized in this Section
6(b) shall include, without limitation, and the Executive's estate and/or
beneficiaries shall be entitled to receive, benefits equal to the benefits
provided by the Company and affiliated companies to the estates and
beneficiaries of peer executives of the Company and such affiliated companies
under such plans, programs, practices and policies relating to death benefits,
if any, in effect on the date of the Executive's death.

         (c) Disability.  If the Executive's employment is terminated by reason
of the Executive's Disability during the Employment Period, this Agreement shall

                                      12
<PAGE>
 
terminate without further obligations to the Executive, other than for payment
of Accrued Obligations and the timely payment or provision of Other Benefits.
Accrued Obligations shall be paid to the Executive in a lump sum in cash within
30 days after the Date of Termination.  With respect to the provision of Other
Benefits, the term Other Benefits as utilized in this Section 6(c) shall
include, without limitation, and the Executive shall be entitled after the
Disability Effective Date to receive, disability and other benefits equal to
those generally provided by the Company and its affiliated companies to disabled
peer executives and/or their families in accordance with such plans programs,
practices and policies relating to disability, if any, in effect generally with
respect to other peer executives and their families at any time of the
Disability.

         (d) Cause; Other than for Good Reason.  If the Executive's employment
shall be terminated for Cause during the Employment Period, this Agreement shall
terminate without further obligations to the Executive other than the obligation
to pay to the Executive (x) his Annual Base Salary through the Date of
Termination, (y) the amount of any compensation previously deferred by the
Executive, and (z) Other Benefits, in each case to the extent theretofore
unpaid.  If the Executive voluntarily terminates employment during the
Employment Period, excluding a termination for Good Reason, this Agreement shall
terminate without further obligations to the Executive, other than for Accrued
Obligations and the timely payment or provision of Other Benefits.  In such
case, all Accrued Obligations shall be paid to the Executive in a lump sum in
cash within 30 days after the Date of Termination.

     7.  Non-exclusivity of Rights.  Nothing in this Agreement shall prevent or
limit the Executive's continuing or future participation in any plan, program,
policy or practice provided by the Company or any of its affiliated companies
and for which the Executive may qualify, nor, subject to Section 12(f), shall
anything herein limit or otherwise affect such rights as the Executive may have
under any contract or agreement with the Company or any of its affiliated
companies.  Amounts which are vested benefits or which the Executive is
otherwise entitled to receive under any plan, policy, practice or program of or
any contract or agreement with the Company or any of its affiliated companies at
or subsequent to the Date of Termination shall be payable in accordance with
such plan, policy, practice or program or contract or agreement except as
explicitly modified by this Agreement.

     8.  Full Settlement.  The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others.  In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and such amounts
shall not be reduced whether or not the Executive obtains

                                      13
<PAGE>
 
other employment.  The Company agrees to pay as incurred, to the full extent
permitted by law, all legal fees and expense which the Executive may reasonably
incur as a result of any contest (regardless of the outcome thereof) by the
Company, the Executive or others of the validity or enforceability of, or
liability under, any provision of this Agreement or any guarantee of performance
thereto (including as a result of any contest by the Executive about the amount
of any payment pursuant to this Agreement), plus in each case interest on any
delayed payment at the applicable Federal rate provided for in Section
7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended (the "Code").

     9.  Certain Additional Payments by the Company.

         (a) Anything in this Agreement to the contrary notwithstanding and
except as set forth below, in the event it shall be determined that any payment
or distribution by the Company to or for the benefit of the Executive (whether
paid or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise, but determined without regard to any additional payments
required under this Section 9) (a "Payment") would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Executive with respect to such excise tax (such excise tax, together with
any such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including without limitation, any income taxes (and any interest
and penalties imposed with respect thereto) and Excise Tax imposed upon the
Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal
to the Excise Tax imposed upon the Payments.  Notwithstanding the foregoing
provisions of this Section 9(a), if it shall be determined that the Executive is
entitled to a Gross-Up Payment, but that the Executive, after taking into
account the Payments and the Gross-Up Payment, would not receive a net after-tax
benefit of at least $50,000 (taking into account both income taxes and any
Excise Tax) as compared to the net after-tax proceeds to the Executive resulting
from an elimination of the Gross-Up Payment and a reduction of the Payments, in
the aggregate, to an amount (the "Reduced Amount") such that the receipt of
Payments would not give rise to any Excise Tax, then no Gross-Up Payment shall
be made to the Executive and the Payments, in the aggregate, shall be reduced to
the Reduced Amount.

         (b) Subject to the provisions of Section 9(c), all determinations
required to be made under this Section 9, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination shall be made by Arthur
Andersen LLP or, as provided below, such other certified public accounting firm
as may be designated by the Executive (the "Accounting Firm") which shall
provide detailed supporting calculations both to the

                                      14
<PAGE>
 
Company and the Executive within 15 business days after the receipt of notice
from the Executive that there has been a Payment, or such earlier time as is
requested by the Company.  In the event that the Accounting Firm is serving as
accountant or auditor for the individual, entity or group effecting the Change
of Control, the Executive shall appoint another nationally recognized accounting
firm to make the determinations required hereunder (which accounting firm shall
then be referred to as the Accounting Firm hereunder).  All fees and expenses of
the Accounting Firm shall be borne solely by the Company.  Any Gross-Up Payment,
as determined pursuant to this Section 9, shall be paid by the Company to the
Executive within five days after the receipt of the Accounting Firm's
determination.  Any determination by the Accounting Firm shall be binding upon
the Company and the Executive.  As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Gross-Up Payments which
will not have been made by the Company should have been made ("Underpayment"),
consistent with the calculations required to be made hereunder.  In the event
that the Company exhausts its remedies pursuant to Section 9(c) and the
Executive thereafter is required to make a payment of any Excise Tax, the
Accounting Firm shall determine the amount of the Underpayment that has occurred
and any such Underpayment shall be promptly paid by the Company to or for the
benefit of the Executive.

         (c) The Executive shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the payment by
the Company of the Gross-Up Payment.  Such notification shall be given as soon
as practicable, but no later than ten business days after the Executive is
informed in writing of such claim, and shall apprise the Company of the nature
of such claim and the date on which such claim is requested to be paid.  The
Executive shall not pay such claim prior to the expiration of the 30-day period
following the date on which he gives such notice to the Company (or such shorter
period ending on the date that any payment of taxes with respect to such claim
is due).  If the Company notifies the Executive in writing prior to the
expiration of such period that it desires to contest such claim the Executive
shall:

          (i) give the Company any information reasonably requested by the
Company relating to such claim,

          (ii) take such action in connection with contesting such claim as the
Company shall reasonably request in writing from time to time, including without
limitation, accepting legal representation with respect to such claim by an
attorney reasonably selected by the Company,

          (iii) cooperate with the Company in good faith in order effectively to
contest such claim, and

                                      15
<PAGE>
 
          (iv) permit the Company to participate in any proceedings relating to
such claims; provided, however, that the Company shall bear and pay directly all
costs and expenses (including additional interest and penalties) incurred in
connection with such costs and shall indemnify and hold the Executive harmless,
on an after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses.  Without limitation on the foregoing provisions
of this Section 9(c), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forego any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct the Executive to pay the tax claimed and sue for a refund or contest the
claim in any permissible manner, and the Executive agrees to prosecute such
contest to determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further provided that any extension of the statute of limitations relating
to payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount. Furthermore, the Company's control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issues raised by the Internal Revenue Service or any other taxing
authority.

         (d) If, after the receipt by the Executive of an amount advanced by the
Company pursuant to Section 9(c), the Executive becomes entitled to receive any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 9(c)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
taxes applicable thereto). If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 9(c), a determination is made that
the Executive shall not be entitled to any refund with respect to such claim and
the Company does not notify the Executive in writing of its intent to contest
such denial of refund prior to the expiration of 30 days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance shall offset, to the extent thereof,
the amount of Gross-Up Payment required to be paid.

     10. Confidential Information.  The Executive shall hold in a fiduciary
capacity for the benefit of the Company all secret or confidential information,
knowledge or data

                                      16
<PAGE>
 
relating to the Company or any of its affiliated companies, and their respective
businesses, which shall have been obtained by the Executive during the
Executive's employment by the Company or any of its affiliated companies,
provided that it shall not apply to information which is or shall become public
knowledge (other than by acts by the Executive or representatives of the
Executive in violation of this Agreement), information that is developed by the
Executive independently of such information, or knowledge or data or information
that is disclosed to the Executive by a third party under no obligation of
confidentiality to the Company.  After termination of the Executive's employment
with the Company, the Executive shall not, without the prior written consent of
the Company or as may otherwise be required by law or legal process, communicate
or divulge any such information, knowledge or data to anyone other than the
Company and those designated by it.  In no event shall an asserted violation of
the provisions of this Section 10 constitute a basis for deferring or
withholding any amounts otherwise payable to the Executive under this Agreement.

     11. Successors.

         (a) This Agreement is personal to the Executive and without the prior
written consent of the Company shall not be assignable by the Executive
otherwise than by will or the laws of descent and distribution.  This Agreement
shall inure to the benefit of and be enforceable by the Executive's legal
representatives.

         (b) This Agreement shall inure to the benefit of and be binding upon
the Company and its successors and assigns.

         (c) The Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company to assume expressly and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor to its business and/or assets as aforesaid which
assumes and agrees to perform this Agreement by operation of law, or otherwise.

     12. Miscellaneous.

         (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Texas, without reference to principles of conflict
of laws. The captions of this Agreement are not part of the provisions hereof
and shall have no force or effect.  This Agreement may not be amended or
modified otherwise than by a written agreement executed by the parties hereto or
their respective successors and legal representatives.

                           INDEMNIFICATION AGREEMENT



  This AGREEMENT, effective as of October 5, 1995 is between Weatherford
Enterra, Inc., a Delaware corporation (the "Company"), and John A. Hill (the
"Director"), a director of the Company;

          WHEREAS, in recognition of Director's need for substantial protection
     against personal liability in order to enhance Director's continued service
     to the Company in an effective manner and of Director's reliance on the
     provisions of the Company's By-Laws requiring indemnification of the
     Director under certain circumstances, and in part to provide Director with
     specific contractual assurance that the protection promised by such By-Laws
     will be available to Director (regardless of, among other things, any
     amendment to or revocation of such By-Laws, any change in the composition
     of the Company's board of Directors or any acquisition transaction relating
     to the Company), the Company wishes to provide in this Agreement for the
     indemnification of, and the advancing of expenses to, Director to the
     fullest extent (whether partial or complete) permitted by law and as set
     forth in this Agreement, and, to the extent insurance is maintained, for
     the continued coverage of Director under the Company's directors' and
     officers' liability insurance policies.

          NOW THEREFORE, in consideration of the premises and of Director
     agreeing to serve or continuing to serve the Company directly or, at its
     request, with another enterprise, and intending to be legally bound hereby,
     the parties hereto agree as follows:

          1. BASIC INDEMNIFICATION ARRANGEMENT

          (a) In the event Director was, is or becomes a party to or witness or
          other participant in, or is threatened to be made a party to or
          witness or other participant in, a Claim (as defined hereinafter) by
          reason of (or arising in part out of) an Indemnifiable Event (as
          defined hereinafter), the Company shall indemnify Director to the
          fullest extent permitted by law as soon as practicable, but in any
          event no later than 30 days after written demand is presented to the
          Company, against any and all Expenses (as defined hereinafter),
          judgments, fines, penalties and amounts paid in settlement of such
          Claim.  If so requested by Director, the Company shall advance (within
          ten business days after such written request) any and all Expenses to
          Director an "Expense Advance".  Notwithstanding anything in this
          Agreement to the contrary, and except as provided in Section 3 hereof,
          prior to a Change in Control (as defined hereinafter), Director shall
          not be entitled to indemnification pursuant to this Agreement in
          connection with any Claim initiated by Director against the Company or
          any director or officer of the Company, unless the Company has joined
          in or consented to the initiation of such Claim.


          (b) Notwithstanding the foregoing, (i) the obligations of the Company
          under Section 1(a) 
<PAGE>
 
          shall be subject to the condition that the Reviewing Party (as defined
          hereinafter) shall not have determined (in a written opinion, in any
          case in which the special independent counsel referred to in Section 2
          hereof is involved) that Director would not be permitted to be
          indemnified under applicable law, and (ii) the obligation of the
          Company to make an Expense Advance pursuant to Section 1(a) shall be
          subject to the condition that, if when and to the extent that the
          Reviewing Party determines that Director would not be permitted to be
          so indemnified under applicable law, the Company shall be entitled to
          be reimbursed by Director (who hereby agrees to reimburse the Company)
          for all such amounts theretofore paid; provided, however, that if
          Director has commenced legal proceedings in a court of competent
          jurisdiction to secure a determination that Director should be
          indemnified under applicable law, any determination made by the
          Reviewing Party that Director would not be permitted to be indemnified
          under applicable law shall not be binding and Director shall not be
          required to reimburse the Company for any Expense Advance until a
          final judicial determination is made with respect thereto (as to which
          all rights of appeal therefrom have been exhausted or lapsed). If
          there has not been a Change in Control, the Reviewing Party shall be
          selected by the Board of Directors, and if there has been such a
          Change in Control, the Reviewing Party shall be the special
          independent counsel referred to in Section 2 hereof. If there has been
          no determination by the Reviewing Party or if the Reviewing Party
          determines that Director substantively would not be permitted to be
          indemnified in whole or in part under applicable law, Director shall
          have the right to commence litigation in any court in the states of
          Texas or Delaware having subject matter jurisdiction thereof and in
          which venue is proper, seeking an initial determination by the court
          or challenging any such determination by the Reviewing Party or any
          aspect thereof, and the Company hereby consents to service of process
          and to appear in any such proceeding. Any determination by the
          Reviewing Party otherwise shall be conclusive and binding on the
          Company and Director.

          2. CHANGE IN CONTROL.   The Company agrees that if there is a Change
          in Control of the Company (other than a Change in Control which has
          been approved by a majority of the Company's Board of Directors who
          were directors immediately prior to such Change in Control), then with
          respect to all matters thereafter arising concerning the rights of
          Director to indemnity payments and Expense Advances under this
          Agreement or any other agreement or Company By-Law now or hereafter in
          effect relating to Claims for Indemnifiable Events, the Company shall
          seek legal advice only from special independent counsel selected by
          Director and approved by the Company (which approval shall not be
          unreasonably withheld), and who has not otherwise performed services
          for the Company or Director within the last five years (other than in
          connection with such matters).  Such counsel, among other things,
          shall render its written opinion to the Company and Director as to
          whether and to what extent Director would be permitted to be
          indemnified under applicable law.  The Company agrees to pay the
          reasonable fees of the special, independent counsel referred to above

                                       2
<PAGE>
 
          and to fully indemnify such counsel against any and all expenses
          (including attorneys' fees), claims, liabilities and damages arising
          out of or relating to this Agreement or its engagement pursuant
          hereto.

          3. INDEMNIFICATION FOR ADDITIONAL EXPENSES.   The Company shall
          indemnify Director against any and all expenses (including attorneys'
          fees) and, if requested by Director, shall (within ten business days
          after such written request) advance such expenses to Director, which
          are incurred by Director in connection with any claim asserted against
          or action brought by Director for  (i) indemnification or advance
          payment of Expenses by the Company under this Agreement or any other
          agreement or Company By-Law now or hereafter in effect relating to
          Claims for Idemnifiable Events and/or  (ii) recovery under any
          directors' and officers' liability insurance policies maintained by
          the Company, regardless of whether Director ultimately is determined
          to be entitled to such indemnification, advance expense payment or
          insurance recovery, as the case may be.

          4. PARTIAL INDEMNITY, ETC.   If Director is  entitled under any
          provision of this Agreement to indemnification by the Company of some
          or a portion of the Expenses, judgments, fines, penalties and amounts
          paid in settlement of a Claim  but not, however, for all of the total
          amount thereof, the Company shall nevertheless indemnify Director for
          the portion thereof to which Director is entitled.  Moreover,
          notwithstanding any other provision of this Agreement, to the extent
          that Director has been successful on the merits or otherwise in
          defense of any or all Claims relating in whole or in part to an
          Indemnifiable Event or in defense of any issue or matter therein,
          including dismissal without prejudice, Director shall be indemnified
          against all Expenses incurred in connection therewith.  In connection
          with any determination by the Reviewing Party or otherwise as to
          whether Director is entitled to be indemnified hereunder, the burden
          of proof shall be on the Company to establish that Director is not so
          entitled.

          5. NO PRESUMPTION.  For purposes of this Agreement, the termination of
          any action, suit or proceeding by judgment, order, settlement (whether
          with or without court approval), conviction, or plea of nolo
          contendere, or its equivalent, shall not create a presumption that
          director did not meet any particular standard of conduct or have any
          particular belief or that a court has determined that indemnification
          is not permitted by applicable law.

          6. NON-EXCLUSIVITY, ETC.   The rights of Director hereunder shall be
          in addition to any other rights Director may have under the Company's
          By-Laws or the Delaware General Corporation Law or otherwise.  To the
          extent that a change in the Delaware General Corporation Law (whether
          by statute or judicial decision) or the Company's By-Laws permits
          greater indemnification by agreement than would be afforded currently
          under the Company's By-Laws and this Agreement, it is the intent of
          the 

                                       3
<PAGE>
 
          parties hereto that Director shall enjoy by this Agreement the greater
          benefits so afforded by such change.

          7. LIABILITY INSURANCE.   To the extent the Company maintains an
          insurance policy or policies providing directors' and officers'
          liability insurance, Director shall be covered by such policy or
          policies, in accordance with its or their terms, to the maximum extent
          of the coverage available for any Company director.

          8. CERTAIN DEFINITIONS.

          other fiduciary holding securities under an employee benefit plan of

          least two- thirds (2/3) of the directors then still in office who
          either were directors at the beginning of the period or whose election
          or nomination for election was previously so approved, cease for any
          reason to constitute a majority thereof, or  (iii) the stockholders of
          the Company approve a merger or consolidation of the Company with any
          other corporation, other than a merger or consolidation which would
          result in the Voting Securities of the Company outstanding immediately
          prior thereto continuing to represent (either by remaining outstanding

          Securities of the Company or such surviving entity outstanding
          immediately after such merger or consolidation or the stockholders of
          the Company approve a plan of complete liquidation of the Company or
          an agreement for the sale or disposition by the Company of all or
          substantially all the Company's assets.

          (b) CLAIM:  any threatened, pending or completed action, suit or

          (d) INDEMNIFIABLE EVENT:   any event or occurrence related to the fact
          that Director is or was a director, officer, employee, agent or
          fiduciary of the Company, or is or was serving at the request of the
          Company as a director, officer, employee, trustee, agent or fiduciary
          of another corporation, partnership, joint venture, employee benefit

          constitute a continuing waiver.

          10. SUBROGATION.  In the event of payment under this Agreement, the
          Company shall be subrogated to the extent of such payment to all of
          the rights of recovery of Director, who shall execute all papers

          12. BINDING EFFECT, ETC.  This Agreement shall be binding upon and
          inure to the benefit of and be enforceable by the parties hereto and
          their respective successors, assigns, including any direct or indirect
          successor by purchase, merger, consolidation or otherwise to all or
          substantially all of the business and/or assets of the Company,
          spouses, heirs, and personal and legal representatives.  This
          Agreement shall continue in effect regardless of whether Director
          continues to serve as a director (or in one of the capacities
          enumerated in Section 8(d) hereof) of the Company or of any other
          enterprise at the Company's request.

<PAGE>
 
          13. SEVERABILITY.  The provisions of this Agreement shall be severable
          in the event that any of the provisions hereof (including any
          provision within a single section, paragraph or sentence) are held by
          a court of competent jurisdiction to be invalid, void or otherwise
          unenforceable, and the remaining provisions shall remain enforceable
          to the fullest extent permitted by law.

          14. GOVERNING LAW.  This Agreement shall be governed by and construed
          and enforced in accordance with the laws of the State of Delaware
          applicable to contracts made and to be performed in such state without
          giving effect to the principles of conflicts of laws.

                           INDEMNIFICATION AGREEMENT


  This AGREEMENT, effective as of October 5, 1995 is between Weatherford
Enterra, Inc., a Delaware corporation (the "Company"), and William E. Macaulay
(the "Director"), a director of the Company;

     WHEREAS, in recognition of Director's need for substantial protection
     against personal liability in order to enhance Director's continued service
     to the Company in an effective manner and of Director's reliance on the
     provisions of the Company's By-Laws requiring indemnification of the
     Director under certain circumstances, and in part to provide Director with
     specific contractual assurance that the protection promised by such By-Laws
     will be available to Director (regardless of, among other things, any
     amendment to or revocation of such By-Laws, any change in the composition
     of the Company's board of Directors or any acquisition transaction relating
     to the Company), the Company wishes to provide in this Agreement for the
     indemnification of, and the advancing of expenses to, Director to the
     fullest extent (whether partial or complete) permitted by law and as set
     forth in this Agreement, and, to the extent insurance is maintained, for
     the continued coverage of Director under the Company's directors' and
     officers' liability insurance policies.

     NOW THEREFORE, in consideration of the premises and of Director agreeing to
     serve or continuing to serve the Company directly or, at its request, with
     another enterprise, and intending to be legally bound hereby, the parties
     hereto agree as follows:

          1. BASIC INDEMNIFICATION ARRANGEMENT

          (a) In the event Director was, is or becomes a party to or witness or
          other participant in, or is threatened to be made a party to or
          witness or other participant in, a Claim (as defined hereinafter) by
          reason of (or arising in part out of) an Indemnifiable Event (as
          defined hereinafter), the Company shall indemnify Director to the
          fullest extent permitted by law as soon as practicable, but in any
          event no later than 30 days after written demand is presented to the
          Company, against any and all Expenses (as defined hereinafter),
          judgments, fines, penalties and amounts paid in settlement of such
          Claim.  If so requested by Director, the Company shall advance (within
          ten business days after such written request) any and all Expenses to
          Director an "Expense Advance".  Notwithstanding anything in this
          Agreement to the contrary, and except as provided in Section 3 hereof,
          prior to a Change in Control (as defined hereinafter), Director shall
          not be entitled to indemnification pursuant to this Agreement in
          connection with any Claim initiated by Director against the Company or
          any director or officer of the Company, unless the Company has joined
          in or consented to the initiation of such Claim.
<PAGE>
 
          (b) Notwithstanding the foregoing, (i) the obligations of the Company
          under Section 1(a) shall be subject to the condition that the
          Reviewing Party (as defined hereinafter) shall not have determined (in
          a written opinion, in any case in which the special independent
          counsel referred to in Section 2 hereof is involved) that Director
          would not be permitted to be indemnified under applicable law, and
          (ii) the obligation of the Company to make an Expense Advance pursuant
          to Section 1(a) shall be subject to the condition that, if when and to
          the extent that the Reviewing Party determines that Director would not
          be permitted to be so indemnified under applicable law, the Company
          shall be entitled to be reimbursed by Director (who hereby agrees to
          reimburse the Company) for all such amounts theretofore paid;
          provided, however, that if Director has commenced legal proceedings in
          a court of competent jurisdiction to secure a determination that
          Director should be indemnified under applicable law, any determination
          made by the Reviewing Party that Director would not be permitted to be
          indemnified under applicable law shall not be binding and Director
          shall not be required to reimburse the Company for any Expense Advance
          until a final judicial determination is made with respect thereto (as
          to which all rights of appeal therefrom have been exhausted or
          lapsed). If there has not been a Change in Control, the Reviewing
          Party shall be selected by the Board of Directors, and if there has
          been such a Change in Control, the Reviewing Party shall be the
          special independent counsel referred to in Section 2 hereof. If there
          has been no determination by the Reviewing Party or if the Reviewing
          Party determines that Director substantively would not be permitted to
          be indemnified in whole or in part under applicable law, Director
          shall have the right to commence litigation in any court in the states
          of Texas or Delaware having subject matter jurisdiction thereof and in
          which venue is proper, seeking an initial determination by the court
          or challenging any such determination by the Reviewing Party or any
          aspect thereof, and the Company hereby consents to service of process
          and to appear in any such proceeding. Any determination by the
          Reviewing Party otherwise shall be conclusive and binding on the
          Company and Director.

          2. CHANGE IN CONTROL.   The Company agrees that if there is a Change
          in Control of the Company (other than a Change in Control which has
          been approved by a majority of the Company's Board of Directors who
          were directors immediately prior to such Change in Control), then with
          respect to all matters thereafter arising concerning the rights of
          Director to indemnity payments and Expense Advances under this
          Agreement or any other agreement or Company By-Law now or hereafter in
          effect relating to Claims for Indemnifiable Events, the Company shall
          seek legal advice only from special independent counsel selected by
          Director and approved by the Company (which approval shall not be
          unreasonably withheld), and who has not otherwise performed services
          for the Company or Director within the last five years (other than in
          connection with such matters).  Such counsel, among other things,
          shall render its written opinion to the Company and Director as to
          whether and to what extent Director would be permitted to be
          indemnified under applicable law.  The Company 

                                       2
<PAGE>
 
          agrees to pay the reasonable fees of the special, independent counsel
          referred to above and to fully indemnify such counsel against any and
          all expenses (including attorneys' fees), claims, liabilities and
          damages arising out of or relating to this Agreement or its engagement
          pursuant hereto.

          3. INDEMNIFICATION FOR ADDITIONAL EXPENSES.   The Company shall
          indemnify Director against any and all expenses (including attorneys'
          fees) and, if requested by Director, shall (within ten business days
          after such written request) advance such expenses to Director, which
          are incurred by Director in connection with any claim asserted against
          or action brought by Director for  (i) indemnification or advance
          payment of Expenses by the Company under this Agreement or any other
          agreement or Company By-Law now or hereafter in effect relating to
          Claims for Idemnifiable Events and/or  (ii) recovery under any
          directors' and officers' liability insurance policies maintained by
          the Company, regardless of whether Director ultimately is determined
          to be entitled to such indemnification, advance expense payment or
          insurance recovery, as the case may be.

          4. PARTIAL INDEMNITY, ETC.   If Director is  entitled under any
          provision of this Agreement to indemnification by the Company of some
          or a portion of the Expenses, judgments, fines, penalties and amounts
          paid in settlement of a Claim  but not, however, for all of the total
          amount thereof, the Company shall nevertheless indemnify Director for
          the portion thereof to which Director is entitled.  Moreover,
          notwithstanding any other provision of this Agreement, to the extent
          that Director has been successful on the merits or otherwise in
          defense of any or all Claims relating in whole or in part to an
          Indemnifiable Event or in defense of any issue or matter therein,
          including dismissal without prejudice, Director shall be indemnified
          against all Expenses incurred in connection therewith.  In connection
          with any determination by the Reviewing Party or otherwise as to
          whether Director is entitled to be indemnified hereunder, the burden
          of proof shall be on the Company to establish that Director is not so
          entitled.

          5. NO PRESUMPTION.  For purposes of this Agreement, the termination of
          any action, suit or proceeding by judgment, order, settlement (whether
          with or without court approval), conviction, or plea of nolo
          contendere, or its equivalent, shall not create a presumption that
          director did not meet any particular standard of conduct or have any
          particular belief or that a court has determined that indemnification
          is not permitted by applicable law.

          6. NON-EXCLUSIVITY, ETC.   The rights of Director hereunder shall be
          in addition to any other rights Director may have under the Company's
          By-Laws or the Delaware General Corporation Law or otherwise.  To the
          extent that a change in the Delaware General Corporation Law (whether
          by statute or judicial decision) or the Company's By-Laws permits
          greater indemnification by agreement than would be afforded 

                                       3
<PAGE>
 
          currently under the Company's By-Laws and this Agreement, it is the
          intent of the parties hereto that Director shall enjoy by this
          Agreement the greater benefits so afforded by such change.

          7. LIABILITY INSURANCE.   To the extent the Company maintains an
          insurance policy or policies providing directors' and officers'
          liability insurance, Director shall be covered by such policy or
          policies, in accordance with its or their terms, to the maximum extent
          of the coverage available for any Company director.

          8. CERTAIN DEFINITIONS.

          (a) CHANGE IN CONTROL:   shall be deemed to have occurred if (i) any

          other fiduciary holding securities under an employee benefit plan of
          the Company or a corporation owned directly or indirectly by the
          stockholders of the Company in substantially the same proportions as
          their ownership of stock of the Company, is or becomes the "beneficial
          owner" (as defined in Rule 13d-3 under said Act), directly or
          indirectly, of securities of the Company representing 20% or more of
          the total voting power represented by the Company's then outstanding

          least two- thirds (2/3) of the directors then still in office who
          either were directors at the beginning of the period or whose election
          or nomination for election was previously so approved, cease for any
          reason to constitute a majority thereof, or  (iii) the stockholders of
          the Company approve a merger or consolidation of the Company with any
          other corporation, other than a merger or consolidation which would
          result in the Voting Securities of the Company outstanding immediately
          prior thereto continuing to represent (either by remaining outstanding
          or by being converted into Voting Securities of the surviving entity)
          at least 80% of the total voting power represented by the Voting
          Securities of the Company or such surviving entity outstanding
          immediately after such merger or consolidation or the stockholders of
          the Company approve a plan of complete liquidation of the Company or
          an agreement for the sale or disposition by the Company of all or
          substantially all the Company's assets.

          (b) CLAIM:  any threatened, pending or completed action, suit or
          proceeding, or any inquiry or investigation whether conducted by the

          witness in or participate in any Claim relating to any Indemnifiable
          Event.

          (d) INDEMNIFIABLE EVENT:   any event or occurrence related to the fact
          that Director is or was a director, officer, employee, agent or
          fiduciary of the Company, or is or was serving at the request of the

          of another corporation, partnership, joint venture, employee benefit

          the particular Claim for which Director is seeking indemnification.

          (f) VOTING SECURITIES:   any securities of the Company which vote
          generally in the election of directors.

          9. AMENDMENTS AND WAIVER.  No supplement, modification or amendment of
          this Agreement shall be binding unless executed in writing by both of
          the parties hereto.  No waiver of any of the provisions of this
          Agreement shall be deemed or shall constitute a waiver of any other
          provisions hereof (whether or not similar) nor shall such waiver
          constitute a continuing waiver.

          10. SUBROGATION.  In the event of payment under this Agreement, the
          Company shall be subrogated to the extent of such payment to all of
          the rights of recovery of Director, who shall execute all papers
          required and shall do everything that may be necessary to secure such
          rights, including the execution of such documents necessary to enable
          the Company effectively to bring suit to enforce such rights.

          11. NO DUPLICATION OF PAYMENTS.   The Company shall not be liable
          under this Agreement to make any payment in connection with any claim

          received payment (under any insurance policy, By-Law or otherwise) of
          the amounts otherwise indemnifiable hereunder.

          12. BINDING EFFECT, ETC.  This Agreement shall be binding upon and
          inure to the benefit of and be enforceable by the parties hereto and
          their respective successors, assigns, including any direct or indirect

          substantially all of the business and/or assets of the Company,

          Agreement shall continue in effect regardless of whether Director
          continues to serve as a director (or in one of the capacities
          enumerated in Section 8(d) hereof) of the Company or of any other
          enterprise at the Company's request.

          13. SEVERABILITY.  The provisions of this Agreement shall be severable
          in the event that any of the provisions hereof (including any
          provision within a single section, paragraph or sentence) are held by
          a court of competent jurisdiction to be invalid, void or otherwise
          unenforceable, and the remaining provisions shall remain enforceable
          to the fullest extent permitted by law.

          14. GOVERNING LAW.  This Agreement shall be governed by and construed
          and enforced in accordance with the laws of the State of Delaware
          applicable to contracts made and to be performed in such state without
          giving effect to the principles of conflicts of laws.

                           INDEMNIFICATION AGREEMENT

  This AGREEMENT, effective as of October 5, 1995 is between Weatherford
Enterra, Inc., a Delaware corporation (the "Company"), and Robert L. Parker, Sr.
(the "Director"), a director of the Company;

          WHEREAS, in recognition of Director's need for substantial protection
     against personal liability in order to enhance Director's continued service
     to the Company in an effective manner and of Director's reliance on the
     provisions of the Company's By-Laws requiring indemnification of the
     Director under certain circumstances, and in part to provide Director with
     specific contractual assurance that the protection promised by such By-Laws
     will be available to Director (regardless of, among other things, any
     amendment to or revocation of such By-Laws, any change in the composition
     of the Company's board of Directors or any acquisition transaction relating
     to the Company), the Company wishes to provide in this Agreement for the
     indemnification of, and the advancing of expenses to, Director to the
     fullest extent (whether partial or complete) permitted by law and as set
     forth in this Agreement, and, to the extent insurance is maintained, for
     the continued coverage of Director under the Company's directors' and
     officers' liability insurance policies.

          NOW THEREFORE, in consideration of the premises and of Director
     agreeing to serve or continuing to serve the Company directly or, at its
     request, with another enterprise, and intending to be legally bound hereby,
     the parties hereto agree as follows:

          1. BASIC INDEMNIFICATION ARRANGEMENT

          (a) In the event Director was, is or becomes a party to or witness or
          other participant in, or is threatened to be made a party to or
          witness or other participant in, a Claim (as defined hereinafter) by
          reason of (or arising in part out of) an Indemnifiable Event (as
          defined hereinafter), the Company shall indemnify Director to the
          fullest extent permitted by law as soon as practicable, but in any
          event no later than 30 days after written demand is presented to the
          Company, against any and all Expenses (as defined hereinafter),
          judgments, fines, penalties and amounts paid in settlement of such
          Claim.  If so requested by Director, the Company shall advance (within
          ten business days after such written request) any and all Expenses to
          Director an "Expense Advance".  Notwithstanding anything in this
          Agreement to the contrary, and except as provided in Section 3 hereof,
          prior to a Change in Control (as defined hereinafter), Director shall
          not be entitled to indemnification pursuant to this Agreement in
          connection with any Claim initiated by Director against the Company or
          any director or officer of the Company, unless the Company has joined
          in or consented to the initiation of such Claim.
<PAGE>
 
          (b) Notwithstanding the foregoing, (i) the obligations of the Company
          under Section 1(a) shall be subject to the condition that the
          Reviewing Party (as defined hereinafter) shall not have determined (in
          a written opinion, in any case in which the special independent
          counsel referred to in Section 2 hereof is involved) that Director
          would not be permitted to be indemnified under applicable law, and
          (ii) the obligation of the Company to make an Expense Advance pursuant
          to Section 1(a) shall be subject to the condition that, if when and to
          the extent that the Reviewing Party determines that Director would not
          be permitted to be so indemnified under applicable law, the Company
          shall be entitled to be reimbursed by Director (who hereby agrees to
          reimburse the Company) for all such amounts theretofore paid;
          provided, however, that if Director has commenced legal proceedings in
          a court of competent jurisdiction to secure a determination that
          Director should be indemnified under applicable law, any determination
          made by the Reviewing Party that Director would not be permitted to be
          indemnified under applicable law shall not be binding and Director
          shall not be required to reimburse the Company for any Expense Advance
          until a final judicial determination is made with respect thereto (as
          to which all rights of appeal therefrom have been exhausted or
          lapsed).  If there has not been a Change in Control, the Reviewing
          Party shall be selected by the Board of Directors, and if there has
          been such a Change in Control, the Reviewing Party shall be the
          special independent counsel referred to in Section 2 hereof.  If there
          has been no determination by the Reviewing Party or if the Reviewing
          Party determines that Director substantively would not be permitted to
          be indemnified in whole or in part under  applicable law, Director
          shall have the right to commence litigation in any court in the states
          of Texas or Delaware having subject matter jurisdiction thereof and in
          which venue is proper, seeking an initial determination by the court
          or challenging any such determination by the Reviewing Party or any
          aspect thereof, and the Company hereby consents to service of process
          and to appear in any such proceeding.  Any determination by the
          Reviewing Party otherwise shall be conclusive and binding on the
          Company and Director.

          2. CHANGE IN CONTROL.   The Company agrees that if there is a Change
          in Control of the Company (other than a Change in Control which has
          been approved by a majority of the Company's Board of Directors who
          were directors immediately prior to such Change in Control), then with
          respect to all matters thereafter arising concerning the rights of
          Director to indemnity payments and Expense Advances under this
          Agreement or any other agreement or Company By-Law now or hereafter in
          effect relating to Claims for Indemnifiable Events, the Company shall
          seek legal advice only from special independent counsel selected by
          Director and approved by the Company (which approval shall not be
          unreasonably withheld), and who has not otherwise performed services
          for the Company or Director within the last five years (other than in
          connection with such matters).  Such counsel, among other things,
          shall render its written opinion to the Company and Director as to
          whether and to what extent Director would be permitted to be
          indemnified under applicable law.  The Company 

                                       2
<PAGE>
 
          agrees to pay the reasonable fees of the special, independent counsel
          referred to above and to fully indemnify such counsel against any and
          all expenses (including attorneys' fees), claims, liabilities and
          damages arising out of or relating to this Agreement or its engagement
          pursuant hereto.

          3. INDEMNIFICATION FOR ADDITIONAL EXPENSES.   The Company shall
          indemnify Director against any and all expenses (including attorneys'
          fees) and, if requested by Director, shall (within ten business days
          after such written request) advance such expenses to Director, which
          are incurred by Director in connection with any claim asserted against
          or action brought by Director for  (i) indemnification or advance
          payment of Expenses by the Company under this Agreement or any other
          agreement or Company By-Law now or hereafter in effect relating to
          Claims for Idemnifiable Events and/or  (ii) recovery under any
          directors' and officers' liability insurance policies maintained by
          the Company, regardless of whether Director ultimately is determined
          to be entitled to such indemnification, advance expense payment or
          insurance recovery, as the case may be.

          4. PARTIAL INDEMNITY, ETC.   If Director is  entitled under any
          provision of this Agreement to indemnification by the Company of some
          or a portion of the Expenses, judgments, fines, penalties and amounts
          paid in settlement of a Claim  but not, however, for all of the total
          amount thereof, the Company shall nevertheless indemnify Director for
          the portion thereof to which Director is entitled.  Moreover,
          notwithstanding any other provision of this Agreement, to the extent
          that Director has been successful on the merits or otherwise in
          defense of any or all Claims relating in whole or in part to an
          Indemnifiable Event or in defense of any issue or matter therein,
          including dismissal without prejudice, Director shall be indemnified
          against all Expenses incurred in connection therewith.  In connection
          with any determination by the Reviewing Party or otherwise as to
          whether Director is entitled to be indemnified hereunder, the burden
          of proof shall be on the Company to establish that Director is not so
          entitled.

          5. NO PRESUMPTION.  For purposes of this Agreement, the termination of
          any action, suit or proceeding by judgment, order, settlement (whether
          with or without court approval), conviction, or plea of nolo
          contendere, or its equivalent, shall not create a presumption that
          director did not meet any particular standard of conduct or have any
          particular belief or that a court has determined that indemnification
          is not permitted by applicable law.

          6. NON-EXCLUSIVITY, ETC.   The rights of Director hereunder shall be
          in addition to any other rights Director may have under the Company's
          By-Laws or the Delaware General Corporation Law or otherwise.  To the
          extent that a change in the Delaware General Corporation Law (whether
          by statute or judicial decision) or the Company's By-Laws permits
          greater indemnification by agreement than would be afforded 

                                       3
<PAGE>
 
          currently under the Company's By-Laws and this Agreement, it is the
          intent of the parties hereto that Director shall enjoy by this
          Agreement the greater benefits so afforded by such change.

          7. LIABILITY INSURANCE.   To the extent the Company maintains an
          insurance policy or policies providing directors' and officers'
          liability insurance, Director shall be covered by such policy or
          policies, in accordance with its or their terms, to the maximum extent
          of the coverage available for any Company director.

          8. CERTAIN DEFINITIONS.

                           INDEMNIFICATION AGREEMENT

  This AGREEMENT, effective as of October 5, 1995 is between Weatherford
Enterra, Inc., a Delaware corporation (the "Company"), and R. Rudolph Reinfrank
(the "Director"), a director of the Company;

          WHEREAS, in recognition of Director's need for substantial protection
     against personal liability in order to enhance Director's continued service
     to the Company in an effective manner and of Director's reliance on the
     provisions of the Company's By-Laws requiring indemnification of the
     Director under certain circumstances, and in part to provide Director with
     specific contractual assurance that the protection promised by such By-Laws
     will be available to Director (regardless of, among other things, any
     amendment to or revocation of such By-Laws, any change in the composition
     of the Company's board of Directors or any acquisition transaction relating
     to the Company), the Company wishes to provide in this Agreement for the
     indemnification of, and the advancing of expenses to, Director to the
     fullest extent (whether partial or complete) permitted by law and as set
     forth in this Agreement, and, to the extent insurance is maintained, for
     the continued coverage of Director under the Company's directors' and
     officers' liability insurance policies.

          NOW THEREFORE, in consideration of the premises and of Director
     agreeing to serve or continuing to serve the Company directly or, at its
     request, with another enterprise, and intending to be legally bound hereby,
     the parties hereto agree as follows:

          1. BASIC INDEMNIFICATION ARRANGEMENT

          (a) In the event Director was, is or becomes a party to or witness or
          other participant in, or is threatened to be made a party to or
          witness or other participant in, a Claim (as defined hereinafter) by
          reason of (or arising in part out of) an Indemnifiable Event (as
          defined hereinafter), the Company shall indemnify Director to the
          fullest extent permitted by law as soon as practicable, but in any
          event no later than 30 days after written demand is presented to the
          Company, against any and all Expenses (as defined hereinafter),
          judgments, fines, penalties and amounts paid in settlement of such
          Claim.  If so requested by Director, the Company shall advance (within
          ten business days after such written request) any and all Expenses to
          Director an "Expense Advance".  Notwithstanding anything in this
          Agreement to the contrary, and except as provided in Section 3 hereof,
          prior to a Change in Control (as defined hereinafter), Director shall
          not be entitled to indemnification pursuant to this Agreement in
          connection with any Claim initiated by Director against the Company or
          any director or officer of the Company, unless the Company has joined
          in or consented to the initiation of such Claim.
<PAGE>
 
          (b) Notwithstanding the foregoing, (i) the obligations of the Company
          under Section 1(a) shall be subject to the condition that the
          Reviewing Party (as defined hereinafter) shall not have determined (in
          a written opinion, in any case in which the special independent
          counsel referred to in Section 2 hereof is involved) that Director
          would not be permitted to be indemnified under applicable law, and
          (ii) the obligation of the Company to make an Expense Advance pursuant
          to Section 1(a) shall be subject to the condition that, if when and to
          the extent that the Reviewing Party determines that Director would not
          be permitted to be so indemnified under applicable law, the Company
          shall be entitled to be reimbursed by Director (who hereby agrees to
          reimburse the Company) for all such amounts theretofore paid;
          provided, however, that if Director has commenced legal proceedings in
          a court of competent jurisdiction to secure a determination that
          Director should be indemnified under applicable law, any determination
          made by the Reviewing Party that Director would not be permitted to be
          indemnified under applicable law shall not be binding and Director
          shall not be required to reimburse the Company for any Expense Advance
          until a final judicial determination is made with respect thereto (as
          to which all rights of appeal therefrom have been exhausted or
          lapsed).  If there has not been a Change in Control, the Reviewing
          Party shall be selected by the Board of Directors, and if there has
          been such a Change in Control, the Reviewing Party shall be the
          special independent counsel referred to in Section 2 hereof.  If there
          has been no determination by the Reviewing Party or if the Reviewing
          Party determines that Director substantively would not be permitted to
          be indemnified in whole or in part under  applicable law, Director
          shall have the right to commence litigation in any court in the states
          of Texas or Delaware having subject matter jurisdiction thereof and in
          which venue is proper, seeking an initial determination by the court
          or challenging any such determination by the Reviewing Party or any
          aspect thereof, and the Company hereby consents to service of process
          and to appear in any such proceeding.  Any determination by the
          Reviewing Party otherwise shall be conclusive and binding on the
          Company and Director.

          2. CHANGE IN CONTROL.   The Company agrees that if there is a Change
          in Control of the Company (other than a Change in Control which has
          been approved by a majority of the Company's Board of Directors who
          were directors immediately prior to such Change in Control), then with
          respect to all matters thereafter arising concerning the rights of
          Director to indemnity payments and Expense Advances under this
          Agreement or any other agreement or Company By-Law now or hereafter in
          effect relating to Claims for Indemnifiable Events, the Company shall
          seek legal advice only from special independent counsel selected by
          Director and approved by the Company (which approval shall not be
          unreasonably withheld), and who has not otherwise performed services
          for the Company or Director within the last five years (other than in
          connection with such matters).  Such counsel, among other things,
          shall render its written opinion to the Company and Director as to
          whether and to what extent Director would be permitted to be
          indemnified under applicable law.  The Company 

                                       2
<PAGE>
 
          agrees to pay the reasonable fees of the special, independent counsel
          referred to above and to fully indemnify such counsel against any and
          all expenses (including attorneys' fees), claims, liabilities and
          damages arising out of or relating to this Agreement or its engagement
          pursuant hereto.

          3. INDEMNIFICATION FOR ADDITIONAL EXPENSES.   The Company shall
          indemnify Director against any and all expenses (including attorneys'
          fees) and, if requested by Director, shall (within ten business days
          after such written request) advance such expenses to Director, which
          are incurred by Director in connection with any claim asserted against
          or action brought by Director for  (i) indemnification or advance
          payment of Expenses by the Company under this Agreement or any other
          agreement or Company By-Law now or hereafter in effect relating to
          Claims for Idemnifiable Events and/or  (ii) recovery under any
          directors' and officers' liability insurance policies maintained by
          the Company, regardless of whether Director ultimately is determined
          to be entitled to such indemnification, advance expense payment or
          insurance recovery, as the case may be.

          4. PARTIAL INDEMNITY, ETC.   If Director is  entitled under any
          provision of this Agreement to indemnification by the Company of some
          or a portion of the Expenses, judgments, fines, penalties and amounts
          paid in settlement of a Claim  but not, however, for all of the total
          amount thereof, the Company shall nevertheless indemnify Director for
          the portion thereof to which Director is entitled.  Moreover,
          notwithstanding any other provision of this Agreement, to the extent
          that Director has been successful on the merits or otherwise in
          defense of any or all Claims relating in whole or in part to an
          Indemnifiable Event or in defense of any issue or matter therein,
          including dismissal without prejudice, Director shall be indemnified
          against all Expenses incurred in connection therewith.  In connection
          with any determination by the Reviewing Party or otherwise as to
          whether Director is entitled to be indemnified hereunder, the burden
          of proof shall be on the Company to establish that Director is not so
          entitled.

          5. NO PRESUMPTION.  For purposes of this Agreement, the termination of
          any action, suit or proceeding by judgment, order, settlement (whether
          with or without court approval), conviction, or plea of nolo
          contendere, or its equivalent, shall not create a presumption that
          director did not meet any particular standard of conduct or have any
          particular belief or that a court has determined that indemnification
          is not permitted by applicable law.

          6. NON-EXCLUSIVITY, ETC.   The rights of Director hereunder shall be
          in addition to any other rights Director may have under the Company's
          By-Laws or the Delaware General Corporation Law or otherwise.  To the
          extent that a change in the Delaware General Corporation Law (whether
          by statute or judicial decision) or the Company's By-Laws permits
          greater indemnification by agreement than would be afforded 

                                       3
<PAGE>
 
          currently under the Company's By-Laws and this Agreement, it is the
          intent of the parties hereto that Director shall enjoy by this
          Agreement the greater benefits so afforded by such change.

          7. LIABILITY INSURANCE.   To the extent the Company maintains an
          insurance policy or policies providing directors' and officers'
          liability insurance, Director shall be covered by such policy or
          policies, in accordance with its or their terms, to the maximum extent
          of the coverage available for any Company director.

          8. CERTAIN DEFINITIONS.

          (a) CHANGE IN CONTROL:   shall be deemed to have occurred if (i) any
          "person" (as such term is used in Sections 13(d) and 14(d) of the
          Securities Exchange Act of 1934, as amended), other than a trustee or
          other fiduciary holding securities under an employee benefit plan of
          the Company or a corporation owned directly or indirectly by the
          stockholders of the Company in substantially the same proportions as
          their ownership of stock of the Company, is or becomes the "beneficial
          owner" (as defined in Rule 13d-3 under said Act), directly or
          indirectly, of securities of the Company representing 20% or more of
          the total voting power represented by the Company's then outstanding
          Voting Securities (as defined hereinafter), or  (ii) during any period
          of two consecutive years, individuals who at the beginning of such
          period constitute the Board of Directors of the Company and any new
          director whose election by the Board of Directors or nomination for
          election by the Company's stockholders was approved by a vote of at
          least two- thirds (2/3) of the directors then still in office who
          either were directors at the beginning of the period or whose election
          or nomination for election was previously so approved, cease for any
          reason to constitute a majority thereof, or  (iii) the stockholders of
          the Company approve a merger or consolidation of the Company with any
          other corporation, other than a merger or consolidation which would
          result in the Voting Securities of the Company outstanding immediately
          prior thereto continuing to represent (either by remaining outstanding
          or by being converted into Voting Securities of the surviving entity)
          at least 80% of the total voting power represented by the Voting
          Securities of the Company or such surviving entity outstanding
          immediately after such merger or consolidation or the stockholders of
          the Company approve a plan of complete liquidation of the Company or
          an agreement for the sale or disposition by the Company of all or
          substantially all the Company's assets.

          (b) CLAIM:  any threatened, pending or completed action, suit or
          proceeding, or any inquiry or investigation whether conducted by the
          Company or any other party, whether civil, criminal, administrative or
          investigative.

          (c) EXPENSES:   include attorneys' fees and all other costs, expenses

          Company as a director, officer, employee, trustee, agent or fiduciary
          of another corporation, partnership, joint venture, employee benefit
          plan, trust or other enterprise, or by reason of anything done or not
          done by Director in any such capacity.

          (e) REVIEWING PARTY:  any appropriate person or body consisting of a
          member or members of the Company's Board of Directors or any other
          person or body appointed by the Board (including the special

          the particular Claim for which Director is seeking indemnification.

          (f) VOTING SECURITIES:   any securities of the Company which vote
          generally in the election of directors.

          9. AMENDMENTS AND WAIVER.  No supplement, modification or amendment of
          this Agreement shall be binding unless executed in writing by both of
          the parties hereto.  No waiver of any of the provisions of this
          Agreement shall be deemed or shall constitute a waiver of any other
          provisions hereof (whether or not similar) nor shall such waiver
          constitute a continuing waiver.

          10. SUBROGATION.  In the event of payment under this Agreement, the
          Company shall be subrogated to the extent of such payment to all of
          the rights of recovery of Director, who shall execute all papers
          required and shall do everything that may be necessary to secure such
          rights, including the execution of such documents necessary to enable
          the Company effectively to bring suit to enforce such rights.

          11. NO DUPLICATION OF PAYMENTS.   The Company shall not be liable
          under this Agreement to make any payment in connection with any claim
          made against Director to the extent Director has otherwise actually
          received payment (under any insurance policy, By-Law or otherwise) of
          the amounts otherwise indemnifiable hereunder.

          12. BINDING EFFECT, ETC.  This Agreement shall be binding upon and

                           INDEMNIFICATION AGREEMENT


  This AGREEMENT, effective as of October 5, 1995 is between Weatherford
Enterra, Inc., a Delaware corporation (the "Company"), and Roger M. Widmann (the
"Director"), a director of the Company;

          WHEREAS, in recognition of Director's need for substantial protection
     against personal liability in order to enhance Director's continued service
     to the Company in an effective manner and of Director's reliance on the
     provisions of the Company's By-Laws requiring indemnification of the
     Director under certain circumstances, and in part to provide Director with
     specific contractual assurance that the protection promised by such By-Laws
     will be available to Director (regardless of, among other things, any
     amendment to or revocation of such By-Laws, any change in the composition
     of the Company's board of Directors or any acquisition transaction relating
     to the Company), the Company wishes to provide in this Agreement for the
     indemnification of, and the advancing of expenses to, Director to the
     fullest extent (whether partial or complete) permitted by law and as set
     forth in this Agreement, and, to the extent insurance is maintained, for
     the continued coverage of Director under the Company's directors' and
     officers' liability insurance policies.

          NOW THEREFORE, in consideration of the premises and of Director
     agreeing to serve or continuing to serve the Company directly or, at its
     request, with another enterprise, and intending to be legally bound hereby,
     the parties hereto agree as follows:

          1. BASIC INDEMNIFICATION ARRANGEMENT

          (a) In the event Director was, is or becomes a party to or witness or
          other participant in, or is threatened to be made a party to or
          witness or other participant in, a Claim (as defined hereinafter) by
          reason of (or arising in part out of) an Indemnifiable Event (as
          defined hereinafter), the Company shall indemnify Director to the
          fullest extent permitted by law as soon as practicable, but in any
          event no later than 30 days after written demand is presented to the
          Company, against any and all Expenses (as defined hereinafter),
          judgments, fines, penalties and amounts paid in settlement of such
          Claim.  If so requested by Director, the Company shall advance (within
          ten business days after such written request) any and all Expenses to
          Director an "Expense Advance".  Notwithstanding anything in this
          Agreement to the contrary, and except as provided in Section 3 hereof,
          prior to a Change in Control (as defined hereinafter), Director shall
          not be entitled to indemnification pursuant to this Agreement in
          connection with any Claim initiated by Director against the Company or
          any director or officer of the Company, unless the Company has joined
          in or consented to the initiation of such Claim.
<PAGE>
 
          (b) Notwithstanding the foregoing, (i) the obligations of the Company
          under Section 1(a) shall be subject to the condition that the
          Reviewing Party (as defined hereinafter) shall not have determined (in
          a written opinion, in any case in which the special independent
          counsel referred to in Section 2 hereof is involved) that Director
          would not be permitted to be indemnified under applicable law, and
          (ii) the obligation of the Company to make an Expense Advance pursuant
          to Section 1(a) shall be subject to the condition that, if when and to
          the extent that the Reviewing Party determines that Director would not
          be permitted to be so indemnified under applicable law, the Company
          shall be entitled to be reimbursed by Director (who hereby agrees to
          reimburse the Company) for all such amounts theretofore paid;
          provided, however, that if Director has commenced legal proceedings in
          a court of competent jurisdiction to secure a determination that
          Director should be indemnified under applicable law, any determination
          made by the Reviewing Party that Director would not be permitted to be
          indemnified under applicable law shall not be binding and Director
          shall not be required to reimburse the Company for any Expense Advance
          until a final judicial determination is made with respect thereto (as
          to which all rights of appeal therefrom have been exhausted or
          lapsed).  If there has not been a Change in Control, the Reviewing
          Party shall be selected by the Board of Directors, and if there has
          been such a Change in Control, the Reviewing Party shall be the
          special independent counsel referred to in Section 2 hereof.  If there
          has been no determination by the Reviewing Party or if the Reviewing
          Party determines that Director substantively would not be permitted to
          be indemnified in whole or in part under  applicable law, Director
          shall have the right to commence litigation in any court in the states
          of Texas or Delaware having subject matter jurisdiction thereof and in
          which venue is proper, seeking an initial determination by the court
          or challenging any such determination by the Reviewing Party or any
          aspect thereof, and the Company hereby consents to service of process
          and to appear in any such proceeding.  Any determination by the
          Reviewing Party otherwise shall be conclusive and binding on the
          Company and Director.

          2. CHANGE IN CONTROL.   The Company agrees that if there is a Change
          in Control of the Company (other than a Change in Control which has
          been approved by a majority of the Company's Board of Directors who
          were directors immediately prior to such Change in Control), then with
          respect to all matters thereafter arising concerning the rights of
          Director to indemnity payments and Expense Advances under this
          Agreement or any other agreement or Company By-Law now or hereafter in
          effect relating to Claims for Indemnifiable Events, the Company shall
          seek legal advice only from special independent counsel selected by
          Director and approved by the Company (which approval shall not be
          unreasonably withheld), and who has not otherwise performed services
          for the Company or Director within the last five years (other than in
          connection with such matters).  Such counsel, among other things,
          shall render its written opinion to the Company and Director as to
          whether and to what extent Director would be permitted to be
          indemnified under applicable law.  The Company 

                                       2
<PAGE>
 
          agrees to pay the reasonable fees of the special, independent counsel
          referred to above and to fully indemnify such counsel against any and
          all expenses (including attorneys' fees), claims, liabilities and
          damages arising out of or relating to this Agreement or its engagement
          pursuant hereto.

          3. INDEMNIFICATION FOR ADDITIONAL EXPENSES.   The Company shall
          indemnify Director against any and all expenses (including attorneys'
          fees) and, if requested by Director, shall (within ten business days
          after such written request) advance such expenses to Director, which
          are incurred by Director in connection with any claim asserted against
          or action brought by Director for  (i) indemnification or advance
          payment of Expenses by the Company under this Agreement or any other
          agreement or Company By-Law now or hereafter in effect relating to
          Claims for Idemnifiable Events and/or  (ii) recovery under any
          directors' and officers' liability insurance policies maintained by
          the Company, regardless of whether Director ultimately is determined
          to be entitled to such indemnification, advance expense payment or
          insurance recovery, as the case may be.

          4. PARTIAL INDEMNITY, ETC.   If Director is  entitled under any
          provision of this Agreement to indemnification by the Company of some
          or a portion of the Expenses, judgments, fines, penalties and amounts
          paid in settlement of a Claim  but not, however, for all of the total
          amount thereof, the Company shall nevertheless indemnify Director for
          the portion thereof to which Director is entitled.  Moreover,
          notwithstanding any other provision of this Agreement, to the extent
          that Director has been successful on the merits or otherwise in
          defense of any or all Claims relating in whole or in part to an
          Indemnifiable Event or in defense of any issue or matter therein,
          including dismissal without prejudice, Director shall be indemnified
          against all Expenses incurred in connection therewith.  In connection
          with any determination by the Reviewing Party or otherwise as to
          whether Director is entitled to be indemnified hereunder, the burden
          of proof shall be on the Company to establish that Director is not so
          entitled.

          5. NO PRESUMPTION.  For purposes of this Agreement, the termination of
          any action, suit or proceeding by judgment, order, settlement (whether
          with or without court approval), conviction, or plea of nolo
          contendere, or its equivalent, shall not create a presumption that
          director did not meet any particular standard of conduct or have any
          particular belief or that a court has determined that indemnification
          is not permitted by applicable law.

          6. NON-EXCLUSIVITY, ETC.   The rights of Director hereunder shall be
          in addition to any other rights Director may have under the Company's
          By-Laws or the Delaware General Corporation Law or otherwise.  To the
          extent that a change in the Delaware General Corporation Law (whether
          by statute or judicial decision) or the Company's By-Laws permits
          greater indemnification by agreement than would be afforded 

                                       3
<PAGE>
 
          currently under the Company's By-Laws and this Agreement, it is the
          intent of the parties hereto that Director shall enjoy by this
          Agreement the greater benefits so afforded by such change.

          7. LIABILITY INSURANCE.   To the extent the Company maintains an
          insurance policy or policies providing directors' and officers'
          liability insurance, Director shall be covered by such policy or
          policies, in accordance with its or their terms, to the maximum extent
          of the coverage available for any Company director.

          8. CERTAIN DEFINITIONS.

          other fiduciary holding securities under an employee benefit plan of

          either were directors at the beginning of the period or whose election
          or nomination for election was previously so approved, cease for any

                           INDEMNIFICATION AGREEMENT


  This AGREEMENT, effective as of October 5, 1995 is between Weatherford
Enterra, Inc., a Delaware corporation (the "Company"), and M. Timothy Carey (the
"Officer"), an officer of the Company;

     WHEREAS, in recognition of Officer's need for substantial protection
     against personal liability in order to enhance Officer's continued service
     to the Company in an effective manner and of Officer's reliance on the
     provisions of the Company's By-Laws requiring indemnification of the
     Officer under certain circumstances, and in part to provide Officer with
     specific contractual assurance that the protection promised by such By-Laws
     will be available to Officer (regardless of, among other things, any

     of the Company's Board of Directors or any acquisition transaction relating
     to the Company), the Company wishes to provide in this Agreement for the
     indemnification of, and the advancing of expenses to, Officer to the
     fullest extent (whether partial or complete) permitted by law and as set
     forth in this Agreement, and, to the extent insurance is maintained, for
     the continued coverage of Officer under the Company's directors' and
     officers' liability insurance policies.

     NOW THEREFORE, in consideration of the premises and of Officer agreeing to
     serve or continuing to serve the Company directly or, at its request, with
     another enterprise, and intending to be legally bound hereby, the parties
     hereto agree as follows:

          1. BASIC INDEMNIFICATION ARRANGEMENT

          (a) In the event Officer was, is or becomes a party to or witness or
          other participant in, or is threatened to be made a party to or
          witness or other participant in, a Claim (as defined hereinafter) by
          reason of (or arising in part out of) an Indemnifiable Event (as
          defined hereinafter), the Company shall indemnify Officer to the
          fullest extent permitted by law as soon as practicable, but in any
          event no later than 30 days after written demand is presented to the
          Company, against any and all Expenses (as defined hereinafter),
          judgments, fines, penalties and amounts paid in settlement of such
          Claim.  If so requested by Officer, the Company shall advance (within
          ten business days after such written request) any and all Expenses to
          Officer (an "Expense Advance").  Notwithstanding anything in this
          Agreement to the contrary, and except as provided in Section 3 hereof,
          prior to a Change in Control (as defined hereinafter), Officer shall
          not be entitled to indemnification pursuant to this Agreement in
          connection with any Claim initiated by Officer against the Company or
          any director or officer of the Company, unless the Company has joined
          in or consented to the initiation of such Claim.

                                       1

          (b) Notwithstanding the foregoing, (i) the obligations of the Company
          under Section 1(a) shall be subject to the condition that the
          Reviewing Party (as defined hereinafter) shall not have determined (in
          a written opinion, in any case in which the special independent
          counsel referred to in Section 2 hereof is involved) that Officer
          would not be permitted to be indemnified under applicable law, and
          (ii) the obligation of the Company to make an Expense Advance pursuant
          to Section 1(a) shall be subject to the condition that, if, when and
          to the extent that the Reviewing Party determines that Officer would
          not be permitted to be so indemnified under applicable law, the
          Company shall be entitled to be reimbursed by Officer (who hereby
          agrees to reimburse the Company) for all such amounts theretofore
          paid; provided, however, that if Officer has commenced legal
          proceedings in a court of competent jurisdiction to secure a
          determination that Officer should be indemnified under applicable law,
          any determination made by the Reviewing Party that Officer would not
          be permitted to be indemnified under applicable law shall not be
          binding and Officer shall not be required to reimburse the Company for
          any Expense Advance until a final judicial determination is made with
          respect thereto (as to which all rights of appeal therefrom have been
          exhausted or lapsed).  If there has not been a Change in Control, the
          Reviewing Party shall be selected by the Board of Directors, and if
          there has been such a Change in Control, the Reviewing Party shall be
          the special independent counsel referred to in Section 2 hereof.  If
          there has been no determination by the Reviewing Party or if the
          Reviewing Party determines that Officer substantively would not be
          permitted to be indemnified in whole or in part under  applicable law,
          Officer shall have the right to commence litigation in any court in
          the states of Texas or Delaware having subject matter jurisdiction
          thereof and in which venue is proper, seeking an initial determination
          by the court or challenging any such determination by the Reviewing
          Party or any aspect thereof, and the Company hereby consents to
          service of process and to appear in any such proceeding.  Any
          determination by the Reviewing Party otherwise shall be conclusive and
          binding on the Company and Officer.

          2. CHANGE IN CONTROL.   The Company agrees that if there is a Change
          in Control of the Company (other than a Change in Control which has
          been approved by a majority of the Company's Board of Directors who
          were directors immediately prior to such Change in Control), then with
          respect to all matters thereafter arising concerning the rights of
          Officer to indemnity payments and Expense Advances under this
          Agreement or any other agreement or Company By-Law now or hereafter in
          effect relating to Claims for Indemnifiable Events, the Company shall
          seek legal advice only from special independent counsel selected by
          Officer and approved by the Company (which approval shall not be
          unreasonably withheld), and who has not otherwise performed services
          for the Company or Officer within the last five years (other than in
          connection with such matters).  Such counsel, among other things,
          shall render its written opinion to the Company and Officer as to
          whether and to what extent Officer would be permitted to be
          indemnified under applicable law.  The Company agrees to pay the
          reasonable fees of the special, independent counsel referred to above
          and to 

                                       2
<PAGE>
 
          fully indemnify such counsel against any and all expenses (including
          attorneys' fees), claims, liabilities and damages arising out of or
          relating to this Agreement or its engagement pursuant hereto.

          3. INDEMNIFICATION FOR ADDITIONAL EXPENSES.   The Company shall
          indemnify Officer against any and all expenses (including attorneys'
          fees) and, if requested by Officer, shall (within ten business days
          after such written request) advance such expenses to Officer, which
          are incurred by Officer in connection with any claim asserted against
          or action brought by Officer for  (i) indemnification or advance
          payment of Expenses by the Company under this Agreement or any other
          agreement or Company By-Law now or hereafter in effect relating to
          Claims for Indemnifiable Events and/or  (ii) recovery under any
          directors' and officers' liability insurance policies maintained by
          the Company, regardless of whether Officer ultimately is determined to
          be entitled to such indemnification, advance expense payment or
          insurance recovery, as the case may be.

          4. PARTIAL INDEMNITY, ETC.   If Officer is  entitled under any
          provision of this Agreement to indemnification by the Company of some
          or a portion of the Expenses, judgments, fines, penalties and amounts
          paid in settlement of a Claim  but not, however, for all of the total
          amount thereof, the Company shall nevertheless indemnify Officer for
          the portion thereof to which Officer is entitled.  Moreover,
          notwithstanding any other provision of this Agreement, to the extent
          that Officer has been successful on the merits or otherwise in defense
          of any or all Claims relating in whole or in part to an Indemnifiable
          Event or in defense of any issue or matter therein, including
          dismissal without prejudice, Officer shall be indemnified against all
          Expenses incurred in connection therewith.  In connection with any
          determination by the Reviewing Party or otherwise as to whether
          Officer is entitled to be indemnified hereunder, the burden of proof
          shall be on the Company to establish that Officer is not so entitled.

          5. NO PRESUMPTION.  For purposes of this Agreement, the termination of
          any action, suit or proceeding by judgment, order, settlement (whether
          with or without court approval), conviction, or plea of nolo
          contendere, or its equivalent, shall not create a presumption that
          Officer did not meet any particular standard of conduct or have any
          particular belief or that a court has determined that indemnification
          is not permitted by applicable law.

          6. NON-EXCLUSIVITY, ETC.   The rights of Officer hereunder shall be in
          addition to any other rights Officer may have under the Company's By-
          Laws or the Delaware General Corporation Law or otherwise.  To the
          extent that a change in the Delaware General Corporation Law (whether
          by statute or judicial decision) or the Company's By-Laws permits
          greater indemnification by agreement than would be afforded currently
          under the Company's By-Laws and this Agreement, it is the intent of
          the parties hereto that Officer shall enjoy by this Agreement the
          greater benefits so afforded by such change.

                                       3
<PAGE>
 
          7. LIABILITY INSURANCE.   To the extent the Company maintains an
          insurance policy or policies providing directors' and officers'
          liability insurance, Officer shall be covered by such policy or
          policies, in accordance with its or their terms, to the maximum extent
          of the coverage available for any Company officer.

          8. CERTAIN DEFINITIONS.

          (a) CHANGE IN CONTROL:   shall be deemed to have occurred if (i) any

          other fiduciary holding securities under an employee benefit plan of
          the Company or a corporation owned directly or indirectly by the
          stockholders of the Company in substantially the same proportions as
          their ownership of stock of the Company, is or becomes the "beneficial
          owner" (as defined in Rule 13d-3 under said Act), directly or
          indirectly, of securities of the Company representing 20% or more of
          the total voting power represented by the Company's then outstanding
          Voting Securities (as defined hereinafter), or  (ii) during any period
          of two consecutive years, individuals who at the beginning of such
          period constitute the Board of Directors of the Company and any new

          least two-thirds (2/3) of the directors then still in office who
          either were directors at the beginning of the period or whose election
          or nomination for election was previously so approved, cease for any
          reason to constitute a majority thereof, or  (iii) the stockholders of
          the Company approve a merger or consolidation of the Company with any
          other corporation, other than a merger or consolidation which would
          result in the Voting Securities of the Company outstanding immediately
          prior thereto continuing to represent (either by remaining outstanding
          or by being converted into Voting Securities of the surviving entity)
          at least 80% of the total voting power represented by the Voting
          Securities of the Company or such surviving entity outstanding
          immediately after such merger or consolidation or the stockholders of
          the Company approve a plan of complete liquidation of the Company or
          an agreement for the sale or disposition by the Company of all or
          substantially all the Company's assets.

          (b) CLAIM:  any threatened, pending or completed action, suit or
          proceeding, or any inquiry or investigation whether conducted by the
          Company or any other party, whether civil, criminal, administrative or
          investigative.

          (c) EXPENSES:   include attorneys' fees and all other costs, expenses
          and obligations paid or incurred in connection with investigating,

          Claim relating to any Indemnifiable Event.

          (d) INDEMNIFIABLE EVENT:   any event or occurrence related to the fact
          that Officer is or was a director, officer, employee, agent or
          fiduciary of the Company, or is or was serving at the request of the
          Company as a director, officer, employee, trustee, agent or fiduciary
          of another corporation, partnership, joint venture, employee benefit

          member or members of the Company's Board of Directors or any other
          person or body appointed by the Board (including the special
          independent counsel referred to in Section 2) who is not a party to
          the particular Claim for which Officer is seeking indemnification.

          (f) VOTING SECURITIES:   any securities of the Company which vote
          generally in the election of directors.

          9. AMENDMENTS AND WAIVER.  No supplement, modification or amendment of
          this Agreement shall be binding unless executed in writing by both of
          the parties hereto.  No waiver of any of the provisions of this
          Agreement shall be deemed or shall constitute a waiver of any other
          provisions hereof (whether or not similar) nor shall such waiver
          constitute a continuing waiver.

          10. SUBROGATION.  In the event of payment under this Agreement, the
          Company shall be subrogated to the extent of such payment to all of
          the rights of recovery of Officer, who shall execute all papers
          required and shall do everything that may be necessary to secure such
          rights, including the execution of such documents necessary to enable
          the Company effectively to bring suit to enforce such rights.

          11. NO DUPLICATION OF PAYMENTS.   The Company shall not be liable
          under this Agreement to make any payment in connection with any claim

          received payment (under any insurance policy, By-Law or otherwise) of
          the amounts otherwise indemnifiable hereunder.

          12. BINDING EFFECT, ETC.  This Agreement shall be binding upon and
          inure to the benefit of and be enforceable by the parties hereto and
          their respective successors, assigns, including any direct or indirect
          successor by purchase, merger, consolidation or otherwise to all or
          substantially all of the business and/or assets of the Company,

          Agreement shall continue in effect regardless of whether Officer
          continues to serve as a director or officer (or in one of the
          capacities enumerated in Section 8(d) hereof) of the Company or of any
          other enterprise at the Company's request.

          13. SEVERABILITY.  The provisions of this Agreement shall be severable
          in the event that any of the provisions hereof (including any
          provision within a single section, paragraph or sentence) are held by
          a court of competent jurisdiction to be invalid, void or otherwise
          unenforceable, and the remaining provisions shall remain enforceable
          to the fullest extent permitted by law.

          14. GOVERNING LAW.  This Agreement shall be governed by and construed
          and enforced in accordance with the laws of the State of Delaware
          applicable to contracts made and to be performed in such state without
          giving effect to the principles of conflicts of laws.

                           INDEMNIFICATION AGREEMENT


  This AGREEMENT, effective as of October 5, 1995 is between Weatherford
Enterra, Inc., a Delaware corporation (the "Company"), and Steven C. Grant (the
"Officer"), an officer of the Company;

     WHEREAS, in recognition of Officer's need for substantial protection
     against personal liability in order to enhance Officer's continued service
     to the Company in an effective manner and of Officer's reliance on the
     provisions of the Company's By-Laws requiring indemnification of the
     Officer under certain circumstances, and in part to provide Officer with
     specific contractual assurance that the protection promised by such By-Laws
     will be available to Officer (regardless of, among other things, any
     amendment to or revocation of such By-Laws, any change in the composition
     of the Company's Board of Directors or any acquisition transaction relating
     to the Company), the Company wishes to provide in this Agreement for the
     indemnification of, and the advancing of expenses to, Officer to the
     fullest extent (whether partial or complete) permitted by law and as set
     forth in this Agreement, and, to the extent insurance is maintained, for
     the continued coverage of Officer under the Company's directors' and
     officers' liability insurance policies.

     NOW THEREFORE, in consideration of the premises and of Officer agreeing to
     serve or continuing to serve the Company directly or, at its request, with
     another enterprise, and intending to be legally bound hereby, the parties
     hereto agree as follows:

          1. BASIC INDEMNIFICATION ARRANGEMENT

          (a) In the event Officer was, is or becomes a party to or witness or
          other participant in, or is threatened to be made a party to or
          witness or other participant in, a Claim (as defined hereinafter) by
          reason of (or arising in part out of) an Indemnifiable Event (as
          defined hereinafter), the Company shall indemnify Officer to the
          fullest extent permitted by law as soon as practicable, but in any
          event no later than 30 days after written demand is presented to the
          Company, against any and all Expenses (as defined hereinafter),
          judgments, fines, penalties and amounts paid in settlement of such
          Claim.  If so requested by Officer, the Company shall advance (within
          ten business days after such written request) any and all Expenses to
          Officer (an "Expense Advance").  Notwithstanding anything in this
          Agreement to the contrary, and except as provided in Section 3 hereof,
          prior to a Change in Control (as defined hereinafter), Officer shall
          not be entitled to indemnification pursuant to this Agreement in
          connection with any Claim initiated by Officer against the Company or
          any director or officer of the Company, unless the Company has joined
          in or consented to the initiation of such Claim.

                                       1

          (b) Notwithstanding the foregoing, (i) the obligations of the Company
          under Section 1(a) shall be subject to the condition that the
          Reviewing Party (as defined hereinafter) shall not have determined (in
          a written opinion, in any case in which the special independent
          counsel referred to in Section 2 hereof is involved) that Officer
          would not be permitted to be indemnified under applicable law, and
          (ii) the obligation of the Company to make an Expense Advance pursuant
          to Section 1(a) shall be subject to the condition that, if, when and
          to the extent that the Reviewing Party determines that Officer would
          not be permitted to be so indemnified under applicable law, the
          Company shall be entitled to be reimbursed by Officer (who hereby
          agrees to reimburse the Company) for all such amounts theretofore
          paid; provided, however, that if Officer has commenced legal
          proceedings in a court of competent jurisdiction to secure a
          determination that Officer should be indemnified under applicable law,
          any determination made by the Reviewing Party that Officer would not
          be permitted to be indemnified under applicable law shall not be
          binding and Officer shall not be required to reimburse the Company for
          any Expense Advance until a final judicial determination is made with
          respect thereto (as to which all rights of appeal therefrom have been
          exhausted or lapsed).  If there has not been a Change in Control, the
          Reviewing Party shall be selected by the Board of Directors, and if
          there has been such a Change in Control, the Reviewing Party shall be
          the special independent counsel referred to in Section 2 hereof.  If
          there has been no determination by the Reviewing Party or if the
          Reviewing Party determines that Officer substantively would not be
          permitted to be indemnified in whole or in part under  applicable law,
          Officer shall have the right to commence litigation in any court in
          the states of Texas or Delaware having subject matter jurisdiction
          thereof and in which venue is proper, seeking an initial determination
          by the court or challenging any such determination by the Reviewing
          Party or any aspect thereof, and the Company hereby consents to
          service of process and to appear in any such proceeding.  Any
          determination by the Reviewing Party otherwise shall be conclusive and
          binding on the Company and Officer.

          2. CHANGE IN CONTROL.   The Company agrees that if there is a Change
          in Control of the Company (other than a Change in Control which has
          been approved by a majority of the Company's Board of Directors who
          were directors immediately prior to such Change in Control), then with
          respect to all matters thereafter arising concerning the rights of
          Officer to indemnity payments and Expense Advances under this
          Agreement or any other agreement or Company By-Law now or hereafter in
          effect relating to Claims for Indemnifiable Events, the Company shall
          seek legal advice only from special independent counsel selected by
          Officer and approved by the Company (which approval shall not be
          unreasonably withheld), and who has not otherwise performed services
          for the Company or Officer within the last five years (other than in
          connection with such matters).  Such counsel, among other things,
          shall render its written opinion to the Company and Officer as to
          whether and to what extent Officer would be permitted to be
          indemnified under applicable law.  The Company agrees to pay the
          reasonable fees of the special, independent counsel referred to above
          and to

          fully indemnify such counsel against any and all expenses (including
          attorneys' fees), claims, liabilities and damages arising out of or
          relating to this Agreement or its engagement pursuant hereto.

          3. INDEMNIFICATION FOR ADDITIONAL EXPENSES.   The Company shall
          indemnify Officer against any and all expenses (including attorneys'
          fees) and, if requested by Officer, shall (within ten business days
          after such written request) advance such expenses to Officer, which
          are incurred by Officer in connection with any claim asserted against
          or action brought by Officer for  (i) indemnification or advance
          payment of Expenses by the Company under this Agreement or any other
          agreement or Company By-Law now or hereafter in effect relating to
          Claims for Indemnifiable Events and/or  (ii) recovery under any
          directors' and officers' liability insurance policies maintained by
          the Company, regardless of whether Officer ultimately is determined to
          be entitled to such indemnification, advance expense payment or
          insurance recovery, as the case may be.

          4. PARTIAL INDEMNITY, ETC.   If Officer is  entitled under any
          provision of this Agreement to indemnification by the Company of some
          or a portion of the Expenses, judgments, fines, penalties and amounts
          paid in settlement of a Claim  but not, however, for all of the total
          amount thereof, the Company shall nevertheless indemnify Officer for
          the portion thereof to which Officer is entitled.  Moreover,
          notwithstanding any other provision of this Agreement, to the extent
          that Officer has been successful on the merits or otherwise in defense
          of any or all Claims relating in whole or in part to an Indemnifiable
          Event or in defense of any issue or matter therein, including
          dismissal without prejudice, Officer shall be indemnified against all
          Expenses incurred in connection therewith.  In connection with any
          determination by the Reviewing Party or otherwise as to whether
          Officer is entitled to be indemnified hereunder, the burden of proof
          shall be on the Company to establish that Officer is not so entitled.

          5. NO PRESUMPTION.  For purposes of this Agreement, the termination of
          any action, suit or proceeding by judgment, order, settlement (whether
          with or without court approval), conviction, or plea of nolo
          contendere, or its equivalent, shall not create a presumption that
          Officer did not meet any particular standard of conduct or have any
          particular belief or that a court has determined that indemnification
          is not permitted by applicable law.

          6. NON-EXCLUSIVITY, ETC.   The rights of Officer hereunder shall be in
          addition to any other rights Officer may have under the Company's By-
          Laws or the Delaware General Corporation Law or otherwise.  To the
          extent that a change in the Delaware General Corporation Law (whether
          by statute or judicial decision) or the Company's By-Laws permits
          greater indemnification by agreement than would be afforded currently
          under the Company's By-Laws and this Agreement, it is the intent of
          the parties hereto that Officer shall enjoy by this Agreement the
          greater benefits so afforded by such change.

                                       3

          7. LIABILITY INSURANCE.   To the extent the Company maintains an
          insurance policy or policies providing directors' and officers'
          liability insurance, Officer shall be covered by such policy or
          policies, in accordance with its or their terms, to the maximum extent
          of the coverage available for any Company officer.

          either were directors at the beginning of the period or whose election
          or nomination for election was previously so approved, cease for any
          reason to constitute a majority thereof, or  (iii) the stockholders of
          the Company approve a merger or consolidation of the Company with any
          other corporation, other than a merger or consolidation which would
          result in the Voting Securities of the Company outstanding immediately

          11. NO DUPLICATION OF PAYMENTS.   The Company shall not be liable

          12. BINDING EFFECT, ETC.  This Agreement shall be binding upon and
          inure to the benefit of and be enforceable by the parties hereto and
          their respective successors, assigns, including any direct or indirect

          other enterprise at the Company's request.

          giving effect to the principles of conflicts of laws.

          Consultant.  Arrangements will be made by the parties with respect to

          Services for the Company, including expenses for entertainment,
          travel, automobile mileage allowance and similar items, will be

          or at the end of the term of this Agreement, as applicable, upon

          expenditures, including receipts, setting forth (in appropriate detail
          with the date, place, amount, names, etc.) the individual items for
          which reimbursement is sought.  Major expense items, such as travel,
          must be authorized prior to Consultant's incurring the expense.

5.   Relationship Between the Parties.

     a.   Consultant is retained and engaged by the Company only for the
          purposes and to the extent set forth in this Agreement, and his
          relation to the Company and its subsidiary and affiliated companies
          shall be that of an independent contractor.  Consultant is solely
          responsible for determining the manner in which the Services are to be
          performed; however, Consultant will exercise professional judgment in
          determining appropriate circumstances when Company management should
          be involved.

     b.   Consultant will be expected to devote sufficient time as is reasonably
          necessary to provide the Services in a manner satisfactory to the
          Company; provided, however, in no event shall Consultant be required
          to expend more than 200 hours per year providing such Services.
          Except as provided in Section 8 below, Consultant shall be free to
          dispose of such portion of his entire time, energy and skill during
          regular business hours, as he is not obligated to devote hereunder to
          the Company and its subsidiary and affiliated companies, to other
          pursuits, persons, firms or corporations.

     c.   Consultant shall not be considered under the provisions of this
          Agreement or otherwise as having an employee status and shall not be
          entitled to participate in any plans, arrangements or distributions by
          the Company or its subsidiary or affiliated companies pertaining to or
          in connection with any pension, stock, bonus, insurance, profit
          sharing or similar benefits for the Company's regular employees.

6.   Taxes.  Consultant will be liable for all taxes imposed on him or his
     business by any government.  Accordingly, the Company will not withhold
     from Consultant's compensation any monies for payment of taxes, including
     income taxes, social security taxes, etc.  Consultant agrees to defend,
     hold harmless and indemnify the Company from and against the payment of any
     taxes on account of Consultant's performance hereunder.

     a.   Inventions and Developments.

          (i)   Consultant agrees to hold in complete trust for the benefit of
                the Company, and to disclose promptly and fully to the Company
                in writing and to assign, and Consultant hereby assigns to the
                Company, any and all inventions, copyrightable works,
                discoveries, innovations or other developments made, discovered,
                conceived or developed by Consultant, solely or jointly with
                others, including the Company, as the result of, in connection
                with or related to the Services (the "Intellectual Property
                Rights").  Any and all such Intellectual Property Rights,
                including without limitation rights in inventions and
                copyrightable works, shall be the sole and exclusive property of
                the Company, whether patentable or not, and Consultant agrees
                that Consultant will assist and fully cooperate in every proper
                way, at the Company's expense, in securing and enforcing, for
                the Company's sole benefit, patents and/or copyrights for such
                Intellectual Property Rights in any and all countries.

          (ii)  Consultant agrees at the request of the Company (but without
                additional compensation from the Company) to execute any and all
                papers and perform all lawful acts that the Company deems
                necessary for the preparation, filing, prosecution and
                maintenance of applications for U.S. Letters Patent and foreign
                letters patent and applications for U.S. copyright registration
                and foreign copyrights on such Intellectual Property Rights and
                to execute such instruments as are necessary to assign to the
                Company, its successors, assigns or nominees, all of
                Consultant's right, title and interest in such Intellectual
                Property Rights and the like, so as to establish or perfect in
                the Company, its successors, assigns or nominees, the entire
                right, title and interest in and to such Intellectual Property
                Rights, and also to execute any instruments necessary or that
                the Company may deem desirable in connection with any
                continuation, renewal or reissue thereof.  All expenses incurred
                by Consultant by reason of the performance of any of the
                obligations set forth herein shall be borne by the Company.

     b.   Work Product.  All work product and generally all materials of any
          form (such as drawings, reports, calculations, analyses, etc.) that
          recite or are based on secret, proprietary or confidential information
          of the Company or corporations affiliated with the Company that are
          received or prepared by Consultant while performing the Services are
          "work for hire" and are the sole property of the Company.  Upon
          completion of the Services or earlier termination of this Agreement
          for whatever reason, Consultant shall forthwith deliver to the Company
          all such materials.  No copies of the same or any part shall be
          retained by Consultant.

                                       4

     c.   Trade Secrets and Confidential Information.  Consultant recognizes,
          understands and acknowledges that Consultant may have access to
          certain trade secrets, financial information, strategic plans and
          other confidential information of the Company and its subsidiary and
          affiliated companies and that such information constitutes valuable,
          special and unique property of the Company and such other companies.
          Consultant shall use his best efforts and exercise utmost diligence to
          protect and guard such information and shall keep such information
          strictly confidential and will not, during the term of this Agreement,
          and for a period of two years after the termination hereof, directly
          or indirectly, disclose any of such trade secrets or confidential
          information to any person, firm, corporation or other entity for any
          reason or purpose whatsoever except to authorized representatives of
          the Company.  In the event of a breach or threatened breach by
          Consultant of the provisions of this Agreement, the Company shall be
          entitled to an injunction restraining Consultant from disclosing, in
          whole or in part, such trade secrets and confidential information.
          Nothing herein shall be construed as prohibiting the Company from
          pursuing any other remedies available to it for such breach or
          threatened breach, including the recovery of damages from Consultant.
          The restrictions on disclosures set forth herein shall not apply to
          any portion of such trade secrets or confidential information that (i)
          through no fault of Consultant is generally available to the public at
          the time of such disclosure to Consultant or thereafter becomes
          generally available to the public, but only when and to the extent
          such information becomes public, (ii) is disclosed to Consultant by a
          third party having the right to disclose such information or (iii) was
          known to Consultant, as shown by suitable evidence, before such
          information was received from the Company or its predecessors in
          interest.  It is understood, for the purpose of this paragraph, that
          specific confidential information disclosed by the Company shall not
          be deemed to be available to the public or in the possession of
          Consultant merely because such information is embraced by more general
          information available to the public or in the possession of
          Consultant.

     d.   In the course of providing Services to the Company, Consultant, with
          respect to discussing the acquisition of other business entities,
          shall not disclose the identity of any such entity or any information,
          whether confidential or not, relating to the Company, without the
          prior written consent of an executive officer of the Company, and then
          only to extent specifically outlined by the Company.

8.   Conflict of Interest.  Consultant agrees that he will not, during the term
     of this Agreement, without the prior written consent of the Company,
     directly or indirectly, enter into competition with the Company in respect
     of any business as conducted by either the Company or Enterra Corporation,
     or by any of their respective subsidiaries or affiliates, prior to the date
     hereof.

9.   No Power to Act on Behalf of the Company.  Consultant shall have no right,
     power or authority to create any obligation, express or implied, or make
     any representation on behalf of the Company except as Consultant may be
     expressly authorized from time to time by the Company in writing and then
     only to the extent of such authorization.
