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

1.   GENERAL

     The unaudited consolidated condensed financial statements included herein
have been prepared by Weatherford International, Inc. (the "Company") pursuant
to the rules and regulations of the Securities and Exchange Commission. These
financial statements reflect all adjustments which the Company considers
necessary for the fair presentation of such financial statements for the interim
periods presented. Although the Company believes that the disclosures in these
financial statements are adequate to make the interim information presented not
misleading, certain information relating to the Company's organization and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles has been condensed or
omitted in this Form 10-Q pursuant to such rules and regulations. These
financial statements should be read in conjunction with the restated audited
consolidated financial statements for the year ended December 31, 1998 and notes
thereto included in the Company's Current Report on Form 8-K filed October 25,
1999. The results of operations for the nine month period ended September 30,
1999 are not necessarily indicative of the results expected for the full year.

     In October 1999, the Board of Directors of the Company approved a plan to
distribute all of the outstanding shares of common stock of its wholly owned
subsidiary, Grant Prideco, Inc. (the "Spinoff"), to holders of the Company's
common stock, $1.00 par value ("Common Stock"). In connection with and prior to
the Spinoff, the Company will transfer its drilling products businesses to Grant
Prideco, Inc. ("Grant Prideco"). As a result, the accompanying financial
statements reflect the operations of Grant Prideco as discontinued operations
(See Note 4).

     Certain reclassifications of prior year balances have been made to conform
such amounts to corresponding 1999 classifications.

3.   BUSINESS COMBINATIONS

     On September 2, 1999, the Company acquired Petroline Wellsystems Limited
("Petroline") for a total consideration of approximately $165.0 million,
consisting of $32.2 million in cash and 3.8 million shares of Common Stock. The
Company also agreed to pay to the sellers additional funds in the event they
resell the shares of Common Stock received by them in the acquisition in certain
market transactions at a price less than $35.175 per share. This obligation
continues until October 2000. Petroline, based in Aberdeen, Scotland, is a
provider of premium completion products and services to the international oil
and gas industry. Petroline is the leading provider of flow control equipment in
the North Sea and was the first company to successfully introduce completion
products using new expandable tube technology.

     On September 15, 1999, the Company acquired Williams Tool Co. ("Williams")
for 1.8 million shares of Common Stock. Williams, based in Fort Smith, Arkansas,
offers a full range of rotating control heads for horizontal, underbalanced and
low hydrostatic drilling operations. Williams products are used to control flow
from the wellbore to reduce the risk of blowouts when oil, gas, geothermal and
coal gas methane wells are being drilled with light fluids.

                WEATHERFORD INTERNATIONAL, INC. AND SUBSIDIARIES
       NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS - (CONTINUED)

     On August 31, 1999, the Company completed the acquisition of Dailey
International Inc. ("Dailey") pursuant to a pre-negotiated plan of
reorganization in bankruptcy. Under the terms of the acquisition, the Company
issued a total of approximately 4.3 million shares of Common Stock to the Dailey
noteholders and stockholders. Of the total number shares issued, the Company
issued approximately 4.0 million shares to the Dailey noteholders and
approximately 0.3 million shares to the Dailey common stockholders. At the time
of the acquisition of Dailey, the Company held approximately 24% of Dailey's
Senior Notes. In the reorganization, the Company contributed those notes to
Dailey and received approximately 1.2 million shares of Common Stock which the
Company holds as treasury shares. Because the Company held Senior Notes of
Dailey, which the Company acquired prior to the bankruptcy at a discount, the
total purchase price for Dailey, excluding assumed liabilities of Dailey that
were not impaired in the bankruptcy, was approximately $185.0 million.

     Dailey is a leading provider of specialty drilling equipment and services
to the oil and gas industry and designs, manufactures and rents proprietary
downhole tools for oil and gas drilling and workover applications worldwide.

     On February 2, 1999, the Company completed a joint venture with GE Capital
Corporation ("GE Capital") in which the Company's compression services
operations were combined with GE Capital's Global Compression Services
operations. The joint venture is known as Weatherford Global Compression
Services. The Company owns 64% of the joint venture and GE Capital owns 36%. The
Company has the right to acquire GE Capital's interest at anytime at a price
equal to a third party market-determined value that is not less than book value.
GE Capital also has the right to require the Company to purchase its interest at
anytime after February 2001 at a market-determined third party valuation as well
as request a public offering of its interest after that date, if the Company has
not purchased its interest by that time.

     On February 8, 1999, the Company completed the acquisition of Christiana
Companies, Inc. ("Christiana") for approximately 4.4 million shares of Common
Stock and $20.6 million cash. In the acquisition, the Company acquired through
Christiana (1) 4.4 million shares of the Company's Common Stock, (2) cash, after
distribution to the Christiana shareholders, equal to the amount of Christiana's
outstanding tax and other liabilities and (3) a one-third interest in Total
Logistic Control, a refrigerated warehouse, trucking and logistics company. The
4.4 million shares of Common Stock acquired are classified as Treasury Stock, at
cost on the accompanying Consolidated Condensed Balance Sheet. Because the
number of shares of Common Stock issued in the Christiana acquisition
approximated the number of shares of Common Stock held by Christiana prior to
the acquisition, the Christiana acquisition had no material effect on the
outstanding number of shares of Common Stock or net equity of the Company.

     The Company also effected various other acquisitions during the nine months
ended September 30, 1999 for total consideration of approximately $56.0 million,
of which $43.6 million was paid in cash and $12.4 million was paid in the form
of shares of Common Stock.

     Through these acquisitions and the acquisitions of technology, the Company
increased its intangible assets by $57.0 million in the nine months ended
September 30, 1999.

     The acquisitions discussed above, were accounted for using the purchase
method of accounting. Results of operations for acquisitions accounted for as
purchases are included in the accompanying consolidated condensed financial
statements since the date of acquisition. The following presents the
consolidated financial information for the Company on a pro forma basis assuming
the Dailey acquisition had occurred on January 1, 1998. All other 1998 and 1999
acquisitions are not material individually nor in the aggregate with same year
acquisitions, therefore, pro forma information is not presented. The pro forma
information set forth below is not necessarily indicative of the results that
actually would have been achieved had such transactions been consummated as of
January 1, 1998, or that may be achieved in the future.

</TABLE>

     Included in net income for the nine months ended September 30, 1998 is an
extraordinary loss, net of taxes recorded by Dailey of $17.6 million. This
extraordinary loss is the result of Dailey's repurchase of their 9 3/4% Senior
Notes in the first quarter of 1998, and represents the excess of the purchase
price for the notes over the carrying value on the date of repurchase.

4.   DISCONTINUED OPERATIONS

     In October 1999, the Board of Directors of the Company approved a plan to
spinoff Grant Prideco. The Spinoff is proposed to be effected through a
distribution by the Company to its stockholders of one share of stock of Grant
Prideco for each two shares of Common Stock held by the Company's stockholders.
The Spinoff is subject to the receipt of a favorable private letter ruling from
the Internal Revenue Service to the effect that receipt of shares of Grant
Prideco common stock should be tax free for federal income tax purposes to the
Company's stockholders and that the Company should not recognize a gain or loss
as a result of the Spinoff. A request for the private letter ruling was filed
with the Internal Revenue Service in July 1999 and that request is in the
process of being reviewed by the Internal Revenue Service. The Company currently
expects that the Spinoff will occur during the first quarter of 2000.

     Summary Financial Results

     The results of operations for Grant Prideco are reflected in the

       NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS - (CONTINUED)

     In connection with the Spinoff, Grant Prideco will issue an unsecured
subordinated note to the Company in the amount of $100.0 million. The $100.0
million obligation will bear interest at an annual rate equal to 10.0%. Interest
payments will be due quarterly, and principal and all unpaid interest will be
due no later than December 31, 2001. Under the terms of the note, Grant Prideco
is required to repay this note with the proceeds of any debt or equity
financing, excluding financing under a credit facility or any equity issued in
connection with a business combination. The indebtedness of Grant Prideco to the
Company will be subordinated to the working capital obligations of Grant Prideco
to its banks. Grant Prideco currently intends to repay the obligation within 12
months from the completion of the Spinoff, pursuant to an anticipated public or
private debt financing. Grant Prideco's ability to repay this indebtedness,
however, will be dependent upon market conditions.

     The Company's historical practice has been to incur indebtedness for its
consolidated group at the parent company level or at a limited number of
subsidiaries, rather than at the operating levels, and to centrally manage
various cash functions. Consequently, a portion of the Company's historical
interest expense has been allocated to discontinued operations. The amount
allocated reflects interest expense associated with the Grant Prideco note
calculated using the Company's average long-term debt interest rates for the
applicable periods. The amount allocated using this methodology results in
amounts consistent with the allocation of interest expense based on a ratio of
the net assets of discontinued operations to the Company's consolidated net
assets plus debt.

     The Completion and Oilfield Services Division and Artificial Lift Division
of the Company purchase drill pipe and other related products from Grant
Prideco. These purchases have been eliminated in the accompanying consolidated
condensed financial statements. The amounts purchased for the three and nine
months ended September 30, 1999 were $15.1 million and $22.7 million,
respectively, and for the three and nine months ended September 30, 1998 were
$1.5 million and $6.1 million, respectively. Such purchases represent Grant
Prideco's cost.

     The results from discontinued operations include a management fee charged
to Grant Prideco of $0.5 million and $1.0 million for the three and nine months
ended September 30, 1999, respectively, and $0.2 million and $0.7 million for
the three and nine months ended September 30, 1998, respectively. The fee is
based on the time devoted to Grant Prideco for accounting, tax, treasury and
risk management services.

     Grant Prideco was charged $1.4 million and $4.3 million of costs related to
the Company's information systems function in the three and nine months ended
September 30, 1999, respectively and $1.4 million and $4.2 million in the three
and nine months ended September 30, 1998, respectively. Information systems
charges were based on direct support provided, equipment usage and number of
system users.

     Proposed Agreements Between The Company and Grant Prideco

     In connection with the Spinoff, Grant Prideco and the Company will enter
into a tax allocation agreement (the "Tax Allocation Agreement"). Under the
terms of the Tax Allocation Agreement, Grant Prideco, is responsible for all
taxes and associated liabilities relating to the historical businesses of Grant
Prideco. The Tax Allocation Agreement also provides that any tax liabilities
associated with the Spinoff shall be assumed and paid by Grant Prideco subject
to certain exceptions relating to changes in control of the Company. The Tax
Allocation Agreement further provides that in the event there is a tax liability
associated with the historical operations of Grant Prideco that is offset by a
tax benefit of the Company, the Company will apply the tax benefit against such
tax liability and will be reimbursed for the value of such tax benefit when and
as the Company would have been able to otherwise utilize that tax benefit for
its own businesses.

     The Company intends to enter into a transition services agreement with
Grant Prideco for a period of one year from the Spinoff date. Under the
agreement, the Company will provide certain services requested by Grant Prideco.
The fee for these services will be based on a cost-plus 10% basis. The
transition services to be provided under this agreement may include accounting,
tax, finance services, employee benefit services, information services,
management information systems and may include any other similar services.

                WEATHERFORD INTERNATIONAL, INC. AND SUBSIDIARIES
       NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS - (CONTINUED)

     The Company also intends to enter into a preferred customer agreement with
Grant Prideco pursuant to which the Company will agree for at least a three year
period to purchase at least 70% of its requirements of drill stem product from
Grant Prideco. The price for those products will be at a price not greater than
that which Grant Prideco sells to its best similarly situated customers. The
Company will be entitled to apply against its purchases a drill stem credit
granted to it in the amount of $15 million, subject to a limitation of the
application of the credit to no more than 20% of any purchase.

5.   SHORT-TERM DEBT

     The Company's unsecured credit agreement provides for borrowings of up to
an aggregate of $250.0 million, consisting of a $200.0 million U.S. credit
facility and a $50.0 million Canadian credit facility. Amounts outstanding under
the facility accrue interest at the U.S. prime rate or a variable rate based on
LIBOR. A commitment fee ranging from 0.09% to 0.20% per annum, depending on the
senior unsecured credit ratings assigned by Standard and Poor's and Moody's
Investor Service to the Company, is payable quarterly on the unused portion of
the facility. The facility contains customary affirmative and negative
covenants, including a maximum debt to capitalization ratio, a minimum interest
coverage ratio, a limitation on liens, and a limitation on asset dispositions.

6.   SALE AND LEASEBACK OF EQUIPMENT

     The Compression Services Division has entered into various sale and
leaseback arrangements where it has sold $239.8 million of compression units and
has a right to sell up to another $110.2 million of compression units. Under
these arrangements, legal title to the compression units are sold to third
parties and leased back to the division under a five year operating lease with a
market-based purchase option.

     As of December 31, 1998, the Compression Services Division had sold
compressors under these arrangements having appraised values of $119.6 million
and had received cash in the amount of $100.0 million and a receivable of $19.6
million. During the nine months ended September 30, 1999, the Compression
Services Division sold additional compressors having an appraised value of
$120.2 million and received cash of $139.8 million. The sales resulted in an
additional pretax deferred gain of approximately $37.3 million, classified as
Deferred Income Taxes and Other on the accompanying Consolidated Condensed
Balance Sheets, which may be deferred until the end of the lease.

     Of the proceeds received by the Compression Services Division from the sale
and leaseback of the compressor units, $100.0 million was distributed to the
Company by the division and $65.4 million was distributed to GE Capital as part
of the joint venture. The remaining proceeds of these sales were utilized by the
joint venture for internal corporate purposes and growth. The Company has
guaranteed certain of the obligations of the joint venture with respect to the
sale of $200.0 million of the compression units. The remaining sales by the
joint venture were done on a non-recourse basis to the Company and are limited
solely to the assets of the joint venture.

     The following table provides future minimum lease payments (in thousands)
under the aforementioned lease as of September 30, 1999:

7.  CUMULATIVE FOREIGN CURRENCY TRANSLATION ADJUSTMENT

   The functional currency for certain of the Company's international
operations is the applicable local currency. Results of operations for foreign
subsidiaries with functional currencies other than the U.S. dollar are
translated using average exchange rates during the period. Assets and
liabilities of these foreign subsidiaries are translated using the exchange
rates in effect at the balance sheet date and the resulting translation
adjustments are included as accumulated other comprehensive loss, a separate
component of stockholders' equity. Currency transaction gains and losses are
reflected in income for the period.

   The net decline in the cumulative foreign currency translation adjustment
from December 31, 1998 to September 30, 1999 was $10.4 million. This decline
primarily reflects the financial impact of the devaluation of Latin American and
European currencies, partially offset by the strengthening Canadian dollar, as
compared to the U.S. dollar.

8.  1998 SPECIAL CHARGES

   In the second quarter of 1998, the Company incurred $113.0 million in
merger and other charges relating to the merger between EVI, Inc. and
Weatherford Enterra, Inc. and a reorganization and rationalization of the
Company's businesses in light of the initial downturn in the industry. These
charges had been fully realized as of December 31, 1998.

   The Company incurred a $47.0 million charge in the fourth quarter of 1998
related to the decline in our markets. As of December 31, 1998, $23.5 million of
these charges had been utilized. The remaining $23.5 million of these charges
were fully utilized in the first half of 1999 as follows:

   o  The severance and related costs included in the fourth quarter charges
      were $7.6 million for the termination of approximately 940 employees
      during the first half of 1999, in accordance with the announced plan.
      These employees had all been terminated by June 30, 1999.

   o  The facility and plant closures of $12.8 million were accrued in the
      fourth quarter of 1998 for the consolidation and closure of approximately
      100 service, manufacturing and administrative facilities in response to
      declining market conditions in the fourth quarter. These facilities had
      all been closed as of June 30, 1999.

   o  The corporate related expenses of $3.1 million recorded in the fourth
      quarter were primarily for the consolidation of technology centers, the
      relocation of corporate offices and the related lease obligations to align
      the corporate cost structure in light of current conditions.

   o  In the first half of 1999, $7.7 million of the 1998 fourth quarter charge
      was utilized by the Completion and Oilfield Services Division, $12.1
      million by the Artificial Lift Systems Division and $3.7 million by
      Corporate.

9.  EARNINGS PER SHARE

   Basic earnings per share is computed by dividing net income by the weighted
average number of shares of common stock outstanding during the year. Diluted
earnings per common share is computed by dividing net income by the weighted
average number of shares of common stock outstanding during the year adjusted
for the dilutive effect of the incremental shares that would have been
outstanding under the Company's stock option and restricted stock plans. The
effect of stock options and restricted stock are not included in the diluted
computation for periods in which a loss from continuing operations occurs
because to do so would have been anti-dilutive. The effect of the Company's 5%
Convertible Subordinated Preferred Equivalent Debentures due 2027 (the
"Debentures") on diluted earnings per share is anti-dilutive and thus is not
included in the calculation.

     (a) The Company evaluates performance and allocates resources based on
     EBITDA, which is calculated as operating income adding back depreciation
     and amortization, excluding the impact of merger costs and other charges.
     Calculations of EBITDA should not be viewed as a substitute to calculations
     under GAAP, in particular operating income, income from continuing
     operations and net income. In addition, EBITDA calculations by one company
     may not be comparable to another company.

     (b) Includes inventory write-downs of $9.9 million which have been
     classified as Cost of Products on the accompanying Consolidated Condensed
     Statements of Operations.

12.  RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, Accounting for
Derivative Instruments and Hedging Activities. SFAS No. 133 provides a
comprehensive and consistent standard for the recognition and measurement of
derivatives and hedging activities. In June 1999 the FASB issued SFAS No. 137,
Accounting for Derivative Instruments and Hedging Activities-Deferral of the
Effective Date of SFAS No. 133, amending the effective date of SFAS No. 133 to
years beginning after June 15, 2000. The Company is currently evaluating the
impact of SFAS No. 133 on its consolidated condensed financial statements.

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

GENERAL

     Our business is conducted through three business segments: (1) Completion
and Oilfield Services, (2) Artificial Lift Systems and (3) Compression Services.
We also historically operated a Drilling Products segment that manufactures and
sells drill pipe and other drill stem products and premium tubulars and
connections. In October 1999, our Board of Directors approved the spinoff by us
of our Drilling Products segment. We have reclassified the operations of this
segment as a discontinued operation in light of the anticipated spinoff of the
segment.

     The spinoff of our Drilling Products segment is proposed to be effected
through a distribution by us to our stockholders of one share of stock of our
Grant Prideco, Inc. subsidiary for each two shares of our common stock held by
our stockholders. The spinoff is subject to our receipt of a favorable private
letter ruling from the Internal Revenue Service on certain aspects of the
spinoff. A request for the private letter ruling was filed with the Internal
Revenue Service in July 1999 and that request is in the process of being
reviewed by the Internal Revenue Service. A registration statement on Form 10
and related preliminary information statement describing the business, assets
and stock of Grant Prideco has been filed with the Securities and Exchange
Commission. We currently expect that the spinoff of our Grant Prideco drilling
products division will occur during the first quarter of 2000.

     The following is a discussion of our results of operations for the three
and nine months ended September 30, 1999 and 1998. This discussion should be
read in conjunction with our financial statements that are included with this
report and our restated financial statements and related Management's Discussion
and Analysis of Financial Condition and Results of Operations for the year ended
December 31, 1998 included in our Current Report on Form 8-K filed October 25,
1999.

     Our discussion of our results and financial condition includes various
forward-looking statements about our markets, the demand for our products and
services and our future results. These statements are based on certain
assumptions that we consider reasonable. For information about these
assumptions, you should refer to our section entitled "Forward-Looking
Statements."

MARKET TRENDS AND OUTLOOK

     Our businesses serve the oil and gas industry. Certain of our products and
services, such as well installation services and our well completion services,
are dependent on the North American and worldwide level of exploration and
development activity. Other products and services, such as our artificial lift
systems and compression services, are dependent on oil and gas production
activity. We currently estimate that between 35% and 45% of our continuing
operations are primarily reliant on drilling activity, with the remainder
primarily related to production activity. All of our businesses, however, are
affected by changes in the worldwide demand and the price of oil and natural
gas.

     During 1998, the price of oil ranged from a high of $17.62 per barrel of
West Texas Intermediate crude to a low of $10.44 per barrel of West Texas
Intermediate crude. The North American rig count also fell from a high of 1,508
rigs to a low in 1998 of 854. The international rig count, which typically
trails the domestic rig count by a number of months, fell in 1998 from a high of
819 to a low of 671. In 1999, the price of oil hit a low of $11.07 per barrel
and the North American and international rig counts reached historical lows of
534 and 556, respectively.

     The downturn in the industry that began in 1998 led our customers to
substantially curtail their exploration and drilling activity during the second
half of 1998 and most of 1999. This reduction in activity resulted in
substantially lower purchases and rentals of equipment manufactured and sold by
us for the exploration and completion of wells. Our field services, such as
fishing and rental, and our sales of artificial lift and other production
equipment and services were also materially impacted by the fall in demand. We
were also impacted by an unprecedented wave of mergers and consolidations among
our customers due to the market conditions. Our customers also canceled, delayed
and rebid many projects to reduce their costs in light of market conditions. In
certain markets in the United States and Canada we believe activity fell by more
than 70%.

     Although market conditions have adversely affected our businesses and their
results in 1999, we made the strategic decision to add to our core competencies
during this downturn and take advantage of desirable acquisitions in our
markets. This decision was based on our belief that the downturn would create
unique opportunities for us to acquire on desirable terms businesses and
capabilities that could serve as the platform for growth in the future. We also
believe that because of the consolidating nature of our industry, many of these
opportunities would not be available again. The principal acquisitions completed
by us in late 1998 and 1999 include:

     (1) Our acquisitions of Cardium Oil Tools and Petroline Wellsystems in the
         second and third quarters of 1999. These two acquisitions significantly
         increased the capabilities of our completion division in the areas of
         flow control, liner hangers and packers and added state of the art sand
         control technology to our completion product offering. We also acquired
         a 50% interest in SubTech, a company that provides products for
         intelligent completions and production automation.
     (2) Our acquisitions of Dailey International Inc. and Williams Tool Co. in
         the third quarter of 1999 and ECD in the second quarter of 1999. These
         three acquisitions have provided us with a complete integrated package
         for the provision of underbalanced drilling services. We now have the
         largest compression fleet in the industry used for underbalanced and
         air drilling, our own proprietary line of pressure control equipment,
         state of the art foam and chemical technology used for underbalanced
         drilling and the largest fleet of nitrogen membrane units. The Dailey
         acquisition also provided us with our own manufactured line of drilling
         and fishing jars for use in our rental and fishing operations.
     (3) Our joint venture with GE Capital which combined our Weatherford
         Compression business with GE's Global Compression business to create
         the second largest natural gas compression fleet in the industry. This
         joint venture has allowed us to expand our compression operations into
         the higher margin higher horsepower business as well as the growing
         international markets.
     (4) Our acquisition of various licenses, technologies and businesses in the
         multi-lateral and re-entry market. These transactions have provided us
         with key technologies and a platform for growth in the growing re-entry
         and multi-lateral markets.

     While we believe the steps we have taken over the last year to position us
for growth in the future should benefit our results as our industry improves,
the recent downturn in our industry has materially and adversely impacted our
results over the last year and a half through substantially lower sales and
margins. Our results have also been affected by higher average fixed and
variable costs associated with the maintenance of our extensive worldwide
manufacturing, sales and service infrastructure during a period of low activity.



                                       15
<PAGE>   17
     Although we have sought over the past year to reduce our costs through
reductions in headcount and locations in light of this most recent industry
downturn, we believe that in order for us to effectively compete in our industry
against much larger competitors we must continue to maintain our market shares
and a strong presence in many of our markets, in particular the higher margin,
long-term growth international markets, notwithstanding the recent downturn. In
addition, we have incurred higher costs associated with our integration and
assimilation of acquisitions and new businesses and products into our
organization during the downturn. All of these circumstances, combined with
record low levels of activity, have materially reduced our margins and operating
profits since mid-1998.

     Recently, the price of oil has increased due to members of the Organization
of Petroleum Exporting Countries reducing production in compliance with
production quotas. Although oil prices have been higher for a number of months,
the increased prices have not yet translated to materially higher overall
activity in our business, in particular in the higher margin international and
offshore markets and the market for higher cost deep and difficult wells.
International activity outside North America is in fact still declining due to
the larger and longer nature of international projects.

     The third quarter of 1999 also represented the first sequential quarterly
improvement that we have seen in our businesses in over a year. This improvement
was primarily due to higher oil prices and increased North American activity.
Activity in the United States and Canada gradually improved during the quarter
and is expected to continue to improve during the fourth quarter of 1999.
Notwithstanding this improvement in North America, we do not expect to see any
major improvements in business activity until 2000, in particular in the
international markets outside North America. Further, the timing of improvements
in our operations will be dependent upon the segment of the industry involved.
Our artificial lift group was the first to benefit from the recent improvements
as production projects were reinstated in light of the higher prices of oil, in
particular heavy oil in Canada. Natural gas activity in Canada is also
increasing. Our completion and downhole services group has recently begun to
benefit from the improved activity in North America. The pickup in this group,
however, is expected to be gradual and we expect that results in this group will
be affected by pricing pressures through at least the remainder of the year, in
particular in the international markets. Our compression business, which is less
affected by day-to-day market factors, is expected to improve slightly as a
result of recent improvements in domestic pricing.

   The following chart sets forth certain historical statistics that are
reflective of the market conditions in which we operate:

     Looking forward into the fourth quarter of 1999 and next year, we are
currently expecting improvements in most of our businesses as exploration and
production activity increase. This improvement will likely be gradual and felt
most strongly in North America. The level of market improvements for our
businesses will be heavily dependent on whether oil and natural gas prices can
remain at or about their present levels and the impact recent market
improvements may have on customer spending. Improvements in North America may
also be partially offset by a slower recovery in the international markets.
Although we believe that the activity levels in our industry are at or near
their bottom, the timing and extent of a recovery is difficult to predict and
will be dependent on many external factors such as compliance with OPEC quotas,
world economic conditions and weather conditions. The extreme volatility of our
markets makes predictions regarding future results difficult.

       viewed as a substitute to calculations under GAAP, in particular cash
       flows from operations, operating income, income from continuing
       operations and net income. In addition, EBITDA calculations by one
       company may not be comparable to another company.

   Our results for the three months ended September 30, 1999 reflected the
adverse market conditions described above in which we were operating. These
conditions had the following effects on our results:

   o   Third quarter 1999 consolidated revenues remained virtually unchanged
       from third quarter 1998 as improvements in North American revenues were
       offset by deterioration in international revenues. Our third quarter 1999
       revenues in North America were $22.7 million higher than they were in the
       third quarter of 1998 due to recent improvements in the North American
       rig count, particularly Canada. International revenues decreased 16.8%
       from third quarter 1998 levels as activity has continued to decline due
       to the consolidations and internal restructurings at the major oil
       companies.



                                       17
<PAGE>   19

   o   The gross profit percentage decreased 4.6% from the third quarter of 1998
       to the third quarter of 1999. This decline reflects the general effects
       of the downturn in the industry, in particular lower activity in the
       higher margin international markets and pricing pressures throughout.
   o   Our selling, general and administrative expenses increased in 1999 due to
       the addition of various new businesses and costs associated with the
       introduction of new products and services.
   o   Operating income declined 59.7% from the third quarter of 1998 due to
       lower pricing, higher operating and administrative costs and
       manufacturing and operational inefficiencies associated with the decline
       in activity. Although we have sought over the past year to reduce our
       costs through reductions in headcount and locations in light of the
       industry downturn, we have elected to maintain our market position and
       international infrastructure in order to capitalize on the market
       recovery when it occurs.
   o   Our corporate expenses as a percentage of revenues increased slightly
       from 1.6% in the third quarter of 1998 to 1.7% in the third quarter of
       1999.
   o   Our effective tax rate for the third quarter of 1999 was 29.0%, as
       compared to 31.8% for the third quarter 1998, due to the mix between
       foreign and U.S. tax attributes for 1999.

   SEGMENT RESULTS

     COMPLETION AND OILFIELD SERVICES

     Our Completion and Oilfield Services Division experienced reductions in
revenue, operating income and margins as the international rig count declined
and the demand for its products and services dropped. In addition, although the
North American rig count has recently improved, a large part of the improvement
has been in the lower margin markets. Pricing pressures were also prevalent in
most of our markets in the quarter. Our Completion and Oilfield Services
Division was also materially affected by higher average fixed and variable costs
associated with the maintenance of its extensive worldwide manufacturing, sales
and service infrastructure during a period of low activity. In addition, costs
associated with the integration and assimilation of recent acquisitions and new
businesses and products into this division during the downturn for growth in the
future have reduced its profitability.

     This division's North American completion and downhole services operations
were the most adversely affected by the downturn and continued to experience
pricing pressures throughout the quarter. In most of our international markets,
we are seeing significantly reduced volumes and are experiencing continued
pricing pressures due to soft demand. Although our completion and downhole
services group has begun to benefit from the improved activity in North America,
any improvements in operating results are expected to be gradual. Further, we
expect that results in this division will be affected by lower international
activity for the remainder of 1999 and pricing pressures through at least the
remainder of the year, in particular in the international markets.

     The following chart sets forth additional data regarding the results of our
Completion and Oilfield Services Division for the third quarters of 1999 and
1998:

     Other material items affecting the results of our Completion and Oilfield
Services Division for the third quarter of 1999 compared to 1998 were:

     o Our domestic revenues for the third quarter of 1999 declined by 16.9% as
       compared to the third quarter of 1998 due to an average rig count
       reduction of 20.8%. Our international revenues, excluding Canada,
       decreased by 18.3% from the third quarter of 1998 due to a rig count
       reduction of 22.9%. The most


                                       18
<PAGE>   20

       significant revenue decreases occurred in Europe, Africa, and the
       Middle East where revenues declined 14.4%, 21.5%, and 28.6%, respectively
       from prior year levels.
     o Gross profit percentage declined in the third quarter of 1999 by 6.3% as
       compared to the third quarter of 1998, due to revenue and pricing
       declines and factory underutilization. The gross profit was further
       reduced by the decline in higher margin international revenues.
     o Selling, general and administrative expenses increased as a percentage
       of revenues from 10.6% in the third quarter of 1998 to 18.9% in the third
       quarter of 1999. The increase primarily reflects a lower revenue base,
       start up costs for new product lines and businesses, costs associated
       with the integration and introduction of newly acquired businesses and
       goodwill amortization associated with 1999 acquisitions. Selling, general
       and administrative costs were negatively impacted by certain acquisitions
       completed in 1999, in particular Dailey International Inc. and Williams
       Tool Co., which had historically high selling, general and administrative
       costs as a percentage of revenues. Because most of these businesses have
       just recently been acquired, we have not yet been able to eliminate
       redundant costs and expenses.
     o Operating income declined $32.6 million in the third quarter of 1999
       from the third quarter of 1998 primarily due to reduced revenues
       associated with industry conditions and higher average costs due to
       manufacturing and operational inefficiencies attributable to lower
       operating levels.

     ARTIFICIAL LIFT SYSTEMS

     Operating results from our Artificial Lift Systems Division are heavily
dependent on oil production activity. Revenues for this division increased
approximately 12% from third quarter 1998 levels, primarily in response to
improved activity levels in North American markets, in particular Canada. This
division has also seen increased sales in the Latin American markets from second
quarter 1999 levels as its artificial lift products have begun to penetrate
those markets utilizing our worldwide infrastructure. We expect the results from
this division to continue to improve during the year. The level of improvement
in this division will depend on our customer's reaction to higher oil prices and
the strength of the recovery.

     The following chart sets forth additional data regarding the results of our
Artificial Lift Systems Division for the third quarters of 1999 and 1998:

    EBITDA....................................        10,979             6,678

     Other material items affecting the results of our Artificial Lift Systems
Division as reflected above for the third quarter of 1999 compared to the third
quarter of 1998 were:

     o The third quarter of 1999 experienced an increase in revenues of 12.5%
       compared to the third quarter of 1998 primarily as a result of recent
       improvements in North American markets. The most significant improvement
       was in Canada where revenues were up 53.5% from third quarter 1998 levels
       as the Canadian rig count increased 19.8% period over period.
     o Gross profit as a percentage of revenues decreased from 37.6% in the
       third quarter of 1998 to 33.9% in the third quarter of 1999 due to
       pricing pressures associated with depressed market conditions that
       occurred during the earlier part of the year. We have recently begun to
       see improvements in pricing as the market for artificial lift products
       has begun its recovery.
     o Selling, general and administrative expenses decreased as a percentage
       of revenues from 34.7% in the third quarter of 1998 to 26.5% in the third
       quarter of 1999 due to cost reductions previously implemented.
     o Operating income as a percentage of revenues improved to 7.6% for the
       third quarter of 1999 as compared to 2.9% for the third quarter of 1998
       due to cost reductions.

COMPRESSION SERVICES

     Our Compression Services Division's results for the third quarter of 1999
reflected increased revenues compared to the third quarter of 1998 as well as
sequential improvement over the second quarter of 1999. Contributing to the
increase in revenues was the February 1999 joint venture with GE Capital and
continued expansion into high value added, long-term contracts.

     Our Compression Services Division recently expanded its international
presence through the award of a seven year contract with YPF S.A. in Argentina
to provide full compression rental, maintenance and service for approximately
$95.0 million over the term of the contract. This project became fully
operational in the third quarter of 1999 and contributed $3.0 million in
revenues.

     The following chart sets forth additional data regarding the results of our
Compression Services Division for the third quarters of 1999 and 1998:

    Minority Interest Expense, Net of Taxes....        1,671               --

    Other material items affecting the results of our Compression Services
Division for 1999 compared to 1998 were:

       o The increase in revenues primarily reflects the impact of the joint
         venture, higher equipment sales, and the YPF contract.
       o Gross profit as a percentage of revenues increased slightly due to a
         better product sales mix. Compressor rental revenues, which generally
         have higher margins than equipment sales, increased as a percentage of
         total revenues from the three months ended September 30, 1998 to the
         three months ended September 30, 1999 due to the joint venture and the
         YPF contract. This improvement was offset, in part, by the increase in
         lower margin equipment sales.
       o The increase in selling, general and administrative expenses reflects
         costs associated with the additional operations acquired in the joint
         venture with GE.

       conditions. Of these charges, $9.9 million related to the write-off of
       inventory has been classified as cost of products.

   (b) EBITDA is calculated by taking operating income and adding back
       depreciation and amortization. We have included an EBITDA calculation
       here because when we look at the performance of our businesses, we give
       consideration to their EBITDA. Calculations of EBITDA should not be
       viewed as a substitute to calculations under GAAP, in particular cash
       flows from operations, operating income, income from continuing
       operations and net income. In addition, EBITDA calculations by one
       company may not be comparable to another company.

   (a) Sales are based on the region of origination and do not reflect sales by

   Our results for the nine months ended September 30, 1999 reflected the
depressed market conditions discussed above. These conditions had the following
effects on our results:

   o   Revenues for the nine months ended September 30, 1999 declined 18.3%
       compared to the same period in 1998. Of the $194.3 million decline in
       revenues from 1998 to 1999, $136.7 million, or 70.4%, was attributable to
       sales in North America.
   o   Selling, general and administrative expenses attributable to the
       segments increased as a percent of revenue due primarily to a lower
       revenue base and startup costs for new product lines and businesses,
       costs associated with



                                       21
<PAGE>   23

       the integration and introduction of newly acquired businesses and
       goodwill amortization associated with 1999 acquisitions. Selling, general
       and administrative costs were negatively impacted by certain acquisitions
       completed in 1999, in particular Dailey International Inc. and Williams
       Tool Co., which had historically high selling, general and administrative
       costs as a percentage of revenues. Because most of these businesses have
       just recently been completed, we have not yet been able to eliminate
       redundant costs and expenses.
   o   Operating income declined $129.1 million to $43.3 million for the nine
       months ended September 30, 1999 as compared to $172.4 million, excluding
       the effect of merger and other charges, for the same period in 1998. This
       resulted from lower revenues, lower margins, and increased selling,
       general and administrative expenses attributable to segments. The
       reduction in margins reflected pricing pressures throughout our markets
       and higher average fixed and variable costs associated with the
       maintenance of our extensive worldwide manufacturing, sales and service
       infrastructure during a period of low activity.
   o   The decrease in corporate expenses from 1998 was primarily attributable
       to consolidation savings.

   SEGMENT RESULTS

     COMPLETION AND OILFIELD SERVICES

     Our Completion and Oilfield Services Division experienced reductions in
revenue, operating income and margins as the rig count declined and demand for
this division's products and services dropped. This division's North American
operations were the most adversely affected by the downturn during the first
half of 1999. International activity outside of North America has also declined
significantly during the year. All our markets in this division experienced
pricing pressures associated with the drop in activity and demand. The on-going
cost of maintaining this division's international infrastructure, which is
necessary for long-term success, and the cost of the integration and
assimilation of acquisitions completed in 1999 and new businesses and products
during the downtown have further eroded its profitability.

     The following chart sets forth additional data regarding the results of our
Completion and Oilfield Services Division:

     (a) Includes merger and other charges of $26.8 million, which consists of
         $3.2 million for facility closures, $23.1 million for write-down of
         assets and $0.5 million for write-off of inventory. The write-off of
         inventory has been classified as cost of products.

     Other material items affecting the results of our Completion and Oilfield
Services Division were:

     o Our North American  revenues for the nine months ended  September 30,
       1999 declined by 33.6% as compared to 1998 due to an average rig count
       reduction of 32.7%.
     o Our international revenues, excluding Canada, decreased by 14.1% in the
       nine months ended September 30, 1999 to $279.5 million, as compared to
       the nine months ended September 30, 1998. The most significant revenue
       decrease occurred in Europe, Africa, and the Middle East where revenues
       decreased 12.6%, 10.9%, and 15.7%, respectively.
     o Our gross profit percentage, excluding the effect of the merger and
       other charges, declined in the nine months ended September 30, 1999 by
       7.9%, from the same period in 1998 due to revenue and pricing declines
       and plant under absorption. The gross profit percentage was further
       reduced by the loss of international sales which tend to have higher
       profit margins.


                                       22
<PAGE>   24

     o Selling, general and administrative expenses increased as a percentage
       of revenues from 11.0% in nine months ended September 30, 1998 to 19.0%
       in 1999. The increase primarily reflects a lower revenue base and start
       up costs relating to new product lines and businesses, costs associated
       with the integration and introduction of newly acquired businesses and
       goodwill amortization associated with 1999 acquisitions. Selling, general
       and administrative costs were negatively impacted by certain acquisitions
       completed in 1999, in particular Dailey International Inc. and Williams
       Tool Co., which had historically high selling, general and administrative
       costs as a percentage of revenues.
     o Operating income, excluding the effect of merger and other charges,
       declined in the nine months ended September 30, 1999 to $36.9 million
       from $155.5 million in 1998 primarily due to reduced revenues associated
       with industry conditions, higher costs and resulting operational
       inefficiencies attributable to lower operating levels.

     ARTIFICIAL LIFT SYSTEMS

     Our Artificial Lift Systems Division's results for the nine months ended
September 30, 1999 compared to the same period in 1998, were down significantly
due to a substantial reduction in demand during the first half of 1999 for our
artificial lift products following the downturn in the industry. This decline
was most pronounced in North America where our sales for the nine months ended
September 30, 1998, represented approximately 82.7% of the division's total
revenue.

         $7.7 million for facility closures, $9.3 million for the write-off of
         inventory and $1.6 million related to the write-down of assets. The
         write-off of inventory has been classified as cost of products.

     Other material items affecting the results of our Artificial Lift Systems
Division as reflected above were:

     o   The nine months ended September 30, 1999 experienced a decline in
         revenues of 25.8% compared to the same period in 1998 due to the
         industry downturn which began to impact this division in the second
         quarter of 1998. Revenues in North America decreased $49.3 million or
         22.3%, from the nine months ended September 30, 1998 to the same period
         in the current year.
     o   Gross profit, excluding the effect of merger and other charges,
         declined to $71.8 million in the nine months ended September 30, 1999
         from $107.8 million in the nine months ended September 30, 1998 due
         primarily to a lower revenue base and pricing declines. Gross profit,
         excluding the effect of the merger and other charges, as a percent of
         revenue remained constant period over period at approximately 36.0%.
     o   Selling, general and administrative expenses declined due to the cost
         reductions implemented in response to the depressed industry
         conditions. Selling, general and administrative expenses increased 4.3%
         as a percent of revenue due to lower revenue levels.
     o   The decline in operating income, excluding the effect of the merger
         and other charges, of $15.8 million for the first nine months of 1999,
         as compared to the same period in 1998 is a result of the sharp decline
         in revenues and pricing pressures.

     COMPRESSION SERVICES

     Our Compression Services Division's results for the nine months ended
September 30, 1999 reflected improved revenues, margins, and operating income as
compared to the same period in 1998. The improvements were primarily
attributable to a better revenue mix and the impact of the joint venture entered
into with GE Capital in February 1999.

     Other material items affecting the results of our Compression Services
Division as reflected above were:

     o   Revenues increased 25.3% from the nine months ended September 30, 1998
         to the nine months ended September 30, 1999 due to the joint venture
         with GE and an increase in equipment sales.
     o   Gross profit as a percentage of revenues increased due to improved
         product and sales mix, offset by pricing pressures in the United States
         rental market.
     o   The increase in selling, general and administrative expenses reflects
         costs associated with the additional operations acquired in the joint
         venture with GE.

1998 SPECIAL CHARGES

     In the second quarter of 1998, we incurred $113.0 million in merger and
other charges relating to the merger between EVI and Weatherford Enterra and a
reorganization and rationalization of our businesses in light of the initial
downturn in the industry. These charges had been fully realized as of December
31, 1998.

     We incurred a $47.0 million charge in the fourth quarter of 1998 related to
the significant decline that occurred in our markets at the end of 1998. As of
December 31, 1998, $23.5 million of these charges had been utilized. The
remaining $23.5 million of these charges were fully realized in the first half
of 1999 as follows:

     o    The severance and related costs included in the fourth quarter
          charges were $7.6 million for the termination of approximately 940
          employees during the first half of 1999, in accordance with the
          announced plan. These employees had all been terminated by June 30,
          1999.

     o    The facility and plant closures of $12.8 million were accrued in the
          fourth quarter of 1998 for the consolidation and closure of
          approximately 100 service, manufacturing and administrative facilities
          in response to declining market conditions in the fourth quarter.
          These facilities had all been closed as of June 30, 1999.

     o    The corporate related expenses of $3.1 million recorded in the fourth
          quarter were primarily for the consolidation of technology centers,
          the relocation of corporate offices and the related lease obligations
          to align the corporate cost structure in light of current conditions.

     o    In the first half of 1999, $7.7 million of the 1998 fourth quarter
          charge was utilized by the Completion and Oilfield Services Division,
          $12.1 million by the Artificial Lift Systems Division and $3.7 million
          by Corporate.

DISCONTINUED OPERATIONS

     Our discontinued operations consist of our Grant Prideco drilling products
division. Results from discontinued operations were as follows:

     o    We had a loss from discontinued operations, net of taxes, for the
          three months ended September 30, 1999, of $14.1 million and income
          from discontinued operations, net of taxes, for the three months ended
          September 30, 1998 of $20.5 million.

     o    We had a loss from discontinued operations, net of taxes, for the
          nine months ended September 30, 1999 of $19.3 million and income from
          discontinued operations, net of taxes, for the nine months ended
          September 30, 1998, of $69.8 million.

     o    Included in the loss from discontinued operations for the three and
          nine months ended September 30, 1999 are $3.5 million, net of taxes,
          of estimated transaction costs which were accrued in the third
          quarter.

     Our discontinued operations results reflect the extreme adverse market
conditions that have existed in the oilfield equipment market since 1998. These
conditions have resulted in substantially lower purchases of drill pipe and
other drill stem products as well as sharply lower purchases of premium tubulars
and connections. Although oil prices have been higher for a number of months,
the increased prices have not yet translated to materially higher drilling
activity. However, orders for drill stem products and other premium tubular
products are increasing, and we expect that demand will continue to improve
absent another material decline in oil prices. We currently expect that demand
for Grant Prideco's drill pipe and other drill stem products will slowly improve
during 2000, with most of the improvement occurring in the second half of 2000.
We expect that results will be significantly better in 2000 than they were in
1999. Nevertheless, demand for these products continues to be highly dependent
upon drilling activity and the price of oil and natural gas and any material
decline in the price of oil and natural gas or drilling activity could result in
further delay in the recovery.

LIQUIDITY AND CAPITAL RESOURCES

     Our current sources of capital are current cash, cash generated from
operations and borrowings under bank lines of credit. We believe that the
current reserves of cash and short-term investments, access to our existing
credit lines and internally generated cash from operations are sufficient to
finance the projected cash requirements of our current and future operations. We
are continually reviewing acquisitions in our markets. Depending upon the size,
nature and timing of an acquisition, we may require additional capital in the
form of either debt, equity or a combination of both.

     The following chart contains information regarding our capital resources
and borrowings and exposures as of September 30, 1999 and December 31, 1998:

     The reduction in our cash and cash equivalents since December 31, 1998, was
primarily attributable to the following:

     o    Borrowings, net of repayments, on term debt and other short-term
          facilities of $127.7 million.


                                       25
<PAGE>   27

     o    Proceeds from the sale and leaseback of compression units of $139.8
          million. Of these proceeds, $65.4 million were subsequently paid to
          GE Capital under terms of the joint venture agreement.
     o    Capital expenditures of property, plant and equipment from continuing
          operations of $134.7  million, including $79.7 million for the
          purchase of compression equipment and related assets for our
          Compression Services Division for use in North America and Argentina.
     o    Capital expenditures of property, plant and equipment from
          discontinued operations of $14.8 million.
     o    Acquisition of new businesses for continuing operations of
          approximately $78.3 million in cash, net of cash acquired.
     o    Acquisition of new businesses for discontinued operations of
          approximately $35.5 million in cash, net of cash acquired, and the
          repayment of approximately $48.0 million in indebtedness incurred for
          Grant Prideco's acquisition of substantially all the outstanding
          shares of the company that owns its Veracruz, Mexico manufacturing
          facility.
     o    Cash inflow from operating activities associated with our continuing
          operations of $24.5 million.
     o    Cash inflow from operating activities of discontinued operations of
          $55.2 million.

     BANKING FACILITIES

     In May 1998, we put in place a five-year unsecured revolving credit
facility that allows us to borrow up to $250.0 million at any time. The facility
consists of a $200.0 million U.S. credit facility and a $50.0 million Canadian
credit facility. As of September 30, 1999, $66.6 million was available under the
credit facility. Borrowings under this facility bear interest at the U.S. prime
rate or a variable rate based on the LIBOR. Our credit facility contains
customary affirmative and negative covenants, including a maximum debt to
capitalization ratio, a minimum interest coverage ratio, a limitation on liens
and a limitation on asset dispositions.

     CONVERTIBLE SUBORDINATED DEBENTURES

     In November 1997, we completed a private placement of $402.5 million
principal amount of our 5% Convertible Subordinated Preferred Equivalent
Debentures due 2027. The Debentures bear interest at an annual rate of 5% and
are convertible into Common Stock at a price of $80 per share. We have the right
to redeem the Debentures at any time on or after November 4, 2000, at redemption
prices provided for in the indenture agreement, and are subordinated in right of
payment of principal and interest to the prior payment in full of certain
existing and future senior indebtedness. We also have the right to defer
payments of interest on the Debentures by extending the quarterly interest
payment period on the Debentures for up to 20 consecutive quarters at any time
when we are not in default in the payment of interest. Under the terms of the
Debentures, the conversion rate for the Debentures will be adjusted following
our spinoff of Grant Prideco. The following sets forth the formula for the
adjustment to the conversion rights of the Debentures for the proposed spinoff.

                                    Conversion Price          x     A - B

                                                                      A

A        =        The current market price per share of our common stock on
                  the payment date for the distribution. The current market
                  price of our common stock for purposes of the adjustment is
                  defined in Section 6.3(g) of the First Supplemental Indenture
                  and is generally defined as the average of the daily closing
                  price of our common stock for the ten trading days ending on
                  the day of the distribution of the Grant Prideco common stock
                  to our stockholders.

B        =        Fair market value of the Grant Prideco common stock to be
                  distributed as determined by our Board of Directors.


     7 1/4% SENIOR NOTES DUE 2006

     We have outstanding $200.0 million of publicly-traded 7 1/4% Senior Notes
due May 15, 2006. Interest on the 7 1/4% Senior Notes is payable semi-annually
on May 15 and November 15 of each year.

     COMPRESSION FINANCING

     Our Compression Services Division has entered into various sale and
leaseback arrangements where it has sold $239.8 million of compression units and
has a right to sell up to another $110.2 million of compression units. Under
these arrangements, legal title to the compression units are sold to third
parties and leased back to the division under a five year operating lease with a
market based purchase option.

     As of December 31, 1998, our Compression Services Division had sold
compressors under these arrangements having appraised values of $119.6 million
and had received cash in the amount of $100.0 million and a receivable of $19.6
million. During the nine months ended September 30, 1999, our Compression
Services Division sold additional compressors having an appraised value of
$120.2 million and received cash of $139.8 million.

     Of the proceeds received by our Compression Services Division from the sale
and leaseback of the compressor units, $100.0 million was distributed to us by
the division and $65.4 million was distributed to GE Capital as part of the
joint venture. The remaining proceeds of these sales were utilized by the joint
venture for internal corporate purposes and growth. We have guaranteed certain
of the obligations of the joint venture with respect to the sale of $200.0
million of the compression units. The remaining sales by the joint venture were
done on a non-recourse basis to us and are limited solely to the assets of the
joint venture.

     Our Compression Services Division continues to review potential projects
for expansion of its operations both domestically and internationally. Depending
on the size of these projects, we expect that the financing of the projects will
be funded with the joint venture's cash flow from operations, proceeds from its
sale and leaseback arrangements or new project or similar type financings.

     GRANT PRIDECO NOTE

     In connection with our proposed spinoff of Grant Prideco, we expect to
receive from Grant Prideco an unsecured subordinated note to us in the amount of
$100.0 million. The $100.0 million obligation to us will bear interest at an
annual rate equal to 10.0%. Interest payments will be due quarterly, and
principal and all unpaid interest will be due no later than December 31, 2001.
Under the terms of the note, Grant Prideco will be required to repay this note
with the proceeds of any debt or equity financing, excluding financing under a
credit facility or any equity issued in connection with a business combination.
The indebtedness of Grant Prideco to us will be subordinated to the working
capital obligations of Grant Prideco to its banks. Grant Prideco currently
intends to repay the obligations within 12 months from the completion of the
spinoff, pursuant to an anticipated public or private debt financing. Grant
Prideco's ability to repay this indebtedness, however, will be dependent upon
market conditions.

     CAPITAL EXPENDITURES

     Our capital expenditures for property, plant and equipment for our
continuing operations during the nine months ended September 30, 1999 were
$134.7 million and primarily related to compression and other rental equipment,
fishing tools and tubular service equipment. Included within our capital
expenditures for the nine months ended September 30, 1999 was $79.7 million for
our Compression Services Division which primarily related to U.S. assets and our
long term contract with YPF. A portion of the 1999 capital expenditures related
to projects initiated at the end of 1998. Capital expenditures for the fourth
quarter of 1999 are expected to be approximately $15.0 million to $20.0 million
and will be primarily maintenance related, excluding our compression operations.
Capital expenditures for our compression operations will be based on contract
needs and the timing of new projects entered into by our compression joint
venture.



                                       27
<PAGE>   29


     Our compression operations are, by their nature, capital intensive and
require substantial investments in compressor units. These capital investments
have historically been financed through existing cash and internally generated
cash flow. We expect that future capital investments by our compression division
will be financed by our compression joint venture through debt, sale and
leaseback arrangements and other similar financing structures that are repaid
from the cash flows generated from the compressor units over the projected term
of rental of the equipment.

     ACQUISITIONS AND JOINT VENTURES

     In February 1999, we completed a joint venture with GE Capital Corporation
in which we combined our compression services operations with GE Capital's
Global Compression's services operations. The joint venture, which is known as
Weatherford Global Compression Services, is the world's second largest provider
of natural gas contract compression services and owns or manages over 4,500
compression units worldwide having approximately 1.1 million horsepower. We own
64% of the joint venture and GE Capital owns 36%. We have the right to acquire
GE Capital's interest at anytime at a price equal to a third party market
determined value that is not less than book value. GE Capital also has the right
to require us to purchase its interest at any time after February 2001 at a
third party market determined value as well as request a public offering of its
interest after that date if we have not purchased its interest by that time.

     In February 1999, we acquired Christiana Companies, Inc. for approximately
4.4 million shares of our common stock and $20.6 million cash. In the
acquisition we acquired through Christiana (i) 4.4 million shares of our common
stock, (ii) cash, after distribution to the Christiana shareholders, equal to
the amount of Christiana's outstanding tax and other liabilities and (iii) a
one-third interest in Total Logistic Control, a refrigerated warehouse, trucking
and logistics company. We acquired Christiana because it gave us a unique
opportunity to own an interest in Total Logistic Control for essentially no
consideration other than our agreement to pursue the acquisition.

     On August 31, 1999, we completed our acquisition of Dailey International
Inc. pursuant to a pre-negotiated plan of reorganization in bankruptcy. Under
the terms of the acquisition, we issued a total of approximately 4.3 million
shares of our common stock to the Dailey noteholders and stockholders. Of the
total number shares issued, we issued approximately 4.0 million shares to the
Dailey noteholders and approximately 0.3 million shares to the Dailey common
stockholders. At the time of our acquisition of Dailey, we held approximately
24% of Dailey's Senior Notes. In the reorganization, we contributed those notes
to Dailey and received approximately 1.2 million shares of our own common stock
which we hold as treasury shares. Because we held Senior Notes of Dailey, which
we acquired prior to the bankruptcy at a discount, the total purchase price for
Dailey, excluding assumed liabilities of Dailey that were not impaired in the
bankruptcy, was approximately $185.0 million.

     Dailey International is a leading provider of specialty drilling equipment
and services to the oil and gas industry and designs, manufactures and rents
proprietary downhole tools for oil and gas drilling and workover applications
worldwide.

     In September 1999, we acquired Petroline Wellsystems Limited for a total
consideration of approximately $165.0 million, consisting of $32.2 million in
cash and 3.8 million shares of our common stock. We also agreed to pay to the
sellers additional funds in the event they resell the shares of our stock
received by them in the acquisition in certain market transactions at a price
less than $35.175 per share. This obligation continues until October 2000.
Petroline, based in Aberdeen, Scotland, is a provider of premium completion
products and services to the international oil and gas industry. Petroline is
the leading provider of flow control equipment in the North Sea and was the
first company to successfully introduce completion products using new expandable
tube technology.

     On September 15, 1999, we acquired Williams Tool Co. for 1.8 million shares
of our common stock. Williams, based in Fort Smith, Arkansas, offers a full
range of rotating control heads for horizontal, underbalanced and low
hydrostatic drilling operations. Williams products are used to control flow from
the wellbore to reduce the risk of blowouts when oil, gas, geothermal and coal
gas methane wells are being drilled with light fluids.

     In the nine months ended September 30, 1999, we also completed eight
acquisitions for our Completion and Oilfield Services Division for consideration
of cash plus assumed debt of $42.6 million and shares of our common stock having
a value of $12.4 million.


                                       28

<PAGE>   30
     We also completed acquisitions during the nine months ended September 30,
1999 that will be integrated into Grant Prideco for total consideration of $36.6
million in cash and assumed debt and shares of our common stock having a value
of $17.3 million.

     Some of our acquisitions have resulted in substantial goodwill associated
with their operations, including goodwill of approximately $327.8 million
relating to our 1999 acquisitions. Through these acquisitions and acquisitions
of technology, we have increased our intangible assets by $57.0 million in 1999.
The amortization expense for goodwill and other intangibles during the nine
months ended September 30, 1999 was $17.0 million.

NEW ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, Accounting for
Derivative Instruments and Hedging Activities. SFAS No. 133 provides a
comprehensive and consistent standard for the recognition and measurement of
derivatives and hedging activities. In June 1999, the FASB issued SFAS No. 137,
Accounting for Derivative Instruments and Hedging Activities-Deferral of the
Effective Date of SFAS No. 133, amending the effective date of SFAS No. 133 to
years beginning after June 15, 2000. We are currently evaluating the impact of
SFAS No. 133 on our consolidated financial statements.

YEAR 2000 MATTERS

     The Year 2000 issue is the risk that information systems, computers,
equipment and products using date-sensitive software or containing computer
chips with two-digit date fields will be unable to correctly process the Year
2000 date change. If not identified and corrected prior to the Year 2000,
failures could occur in our software, hardware, equipment and products and those
of our suppliers, vendors and customers that could result in interruptions in
our business. Any failure could have a material impact on us.

     In response to the Year 2000 issue, we have prepared and implemented a plan
("Year 2000 Plan") to assess and remediate significant Year 2000 issues in our:

     o    Information technology systems ("IT"), including computer software and
          hardware.
     o    Non-information technology systems utilizing date-sensitive software
          or computer chips ("Non-IT"), including products, facilities,
          equipment and other infrastructures.

     Our management information systems department ("MIS Department"), together
with our technical and engineering employees and outside consultants, are
responsible for the implementation and execution of the Year 2000 Plan. Our Year
2000 Plan is a comprehensive, multi-step process covering our IT and Non-IT
systems. The primary phases of the Year 2000 Plan are:

     (1)  Assessing and analyzing our systems to identify those that are not
          Year 2000 ready.
     (2)  Preparing cost and resource estimates to repair, remediate or replace
          all systems that are not Year 2000 ready.
     (3)  Developing a Company-wide, detailed strategy to coordinate the repair
          or replacement of all systems that are not Year 2000 ready.
     (4)  Implementing the strategy to make all systems Year 2000 ready.
     (5)  Verifying, testing and auditing the Year 2000 readiness of all
          systems.

     As of September 30, 1999, the first, second, third and fourth phases of the
Year 2000 Plan had been completed. The fifth phase will be completed by the end
of the fourth quarter of 1999. Any unexpected delays or problems that prevent us
from completing the final phase of the Year 2000 Plan in a timely manner could
have a material adverse impact on us.

     In addition to our assessment and review of our own systems, we are
communicating with our third-party contractors, such as vendors, service
providers and customers, for the purpose of evaluating their readiness for the
Year 2000 and determining the extent to which we may be affected by the
remediation of their systems, software, applications and products. We continue
to review and evaluate the Year 2000 programs of our significant third-party
contractors. However, there can be no guarantee that our IT and Non-IT systems
of third-party contractors


                                       29
<PAGE>   31

will be Year 2000 ready or that the failure of any such party to have Year 2000
ready systems would not result in interruptions in our business which could have
a material adverse impact on us.

     In connection with the implementation and completion of the Year 2000 Plan,
we currently expect to incur pretax expenditures of approximately $9.5 million.
We have incurred approximately $9.2 million of such expenditures from January
1998 through September 30, 1999, of which, approximately $7.6 million has been
incurred in connection with the replacement of our business application software
and approximately $1.6 million has been incurred in connection with the
replacement of certain IT hardware systems. We intend to continue to fund the
Year 2000 Plan expenditures with working capital and third-party lease
financing. Based upon information currently available, we believe that
expenditures associated with achieving Year 2000 compliance will not have a
material impact on operating results. However, any unanticipated problems
relating to the Year 2000 issue that result in materially increased expenditures
could have a material adverse impact on us.

     The 1999 expenditures associated with the Year 2000 Plan represent
approximately 15% of our 1999 MIS Department's budget. Various other IT projects
that are not related to the Year 2000 issue have been deferred due to the Year
2000 efforts. The effects of these delays are not expected to have a material
impact on us.

     We are unable to predict the most likely worst case Year 2000 scenario. We
are preparing a contingency plan in response to Year 2000 worst case scenario
and we estimate no lost revenues due to Year 2000 issues. However, there can be
no assurance that any contingency plan developed by us will be sufficient to
alleviate or remediate any significant Year 2000 problems that we may
experience.

     The above discussion of our efforts and expectations relating to the risks
and uncertainties associated with the Year 2000 issues and our Year 2000 Plan
contain forward-looking statements as defined in the Private Securities
Litigation Reform Act of 1995. These statements involve predictions and
expectations concerning our ability to achieve Year 2000 compliance, the amount
of costs and expenses related to the Year 2000 issue and the effect the Year
2000 issue may have on business and results of operations. Certain risks and
uncertainties may cause actual results to be materially different from the
projected or expected results, the overall effect of which may have a materially
adverse impact on us. These risks and uncertainties include, but are not limited
to, unanticipated problems and costs identified in all phases of the Year 2000
Plan, our ability to successfully implement the Year 2000 Plan in a timely
manner and the ability of our suppliers, vendors and customers to make their
systems and products Year 2000 compliant.

EXPOSURES

     INDUSTRY EXPOSURE

     Substantially all of our customers are engaged in the energy industry. This
concentration of customers may impact our overall exposure to credit risk,
either positively or negatively, in that customers may be similarly affected by
changes in economic and industry conditions. Many of our customers have slowed
the payment of their accounts in light of current industry conditions and others
have experienced greater financial difficulties in meeting their payment terms.
We perform ongoing credit evaluations of our customers and do not generally
require collateral in support of our trade receivables. We maintain reserves for
potential credit losses, and, generally, actual losses have historically been
within our expectations.

     LITIGATION AND ENVIRONMENTAL EXPOSURE

     In the ordinary course of business, we become the subject of various claims
and litigation. We maintain insurance to cover many of our potential losses and
we are subject to various self-retentions and deductibles with respect to our
insurance. Although we are subject to various ongoing items of litigation, we do
not believe that any of the items of litigation that we are currently subject to
will result in any material uninsured losses to us. It is, however, possible
that an unexpected judgment could be rendered against us in cases in which we
could be uninsured and beyond the amounts that we currently have reserved or
anticipate incurring for that matter.



                                       30
<PAGE>   32


     We are also subject to various federal, state and local laws and
regulations relating to the energy industry in general and the environment in
particular. Environmental laws have in recent years become more stringent and
have generally sought to impose greater liability on a larger number of
potentially responsible parties. While we are not currently aware of any
situation involving an environmental claim that would likely have a material
adverse effect on our business, it is always possible that an environmental
claim with respect to one or more of our current businesses or a business or
property that one of our predecessors owned or used could arise that could
involve the expenditure of a material amount of funds.

     INTERNATIONAL EXPOSURE

     Like most multinational oilfield service companies, we have 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, that are inherently subject to risks of war, political
disruption, civil disturbance and policies that may:

     o    disrupt oil and gas exploration and production activities;
     o    restrict the movement of funds;
     o    lead to U.S. government or international sanctions; and
     o    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 resumed eventually in
relation to market forces. Certain areas, including the CIS, Algeria, Nigeria,
parts of the Middle East, the Asia-Pacific region and Latin America, have been
subjected to political disruption which has negatively impacted results of
operations following such events.

     CURRENCY EXPOSURE

     A single European currency ("the Euro") was introduced on January 1, 1999,
at which time the conversion rates between legacy currencies and the Euro were
set for 11 participating member countries. However, the legacy currencies in
those countries will continue to be used as legal tender through January 1,
2002. Thereafter, the legacy currencies will be canceled, and the Euro bills and
coins will be used in the 11 participating countries. We are currently
evaluating the effect of the Euro on our consolidated financial statements and
our business operations; however, we do not foresee that the transition to the
Euro will have a significant impact.

     Approximately 69.3% of our net assets from continuing operations are
located outside the United States and are carried on our books in local
currencies. Changes in those currencies in relation to the U.S. dollar result in
translation adjustments which are reflected as accumulated other comprehensive
loss in the stockholders' equity on our balance sheet. We recorded a $10.4
million adjustment to our equity account for the nine months ended September 30,
1999 to reflect the net impact of the decline in Latin American and European
currencies, partially offset by the strengthening Canadian dollar, against the
U.S. dollar.


FORWARD-LOOKING STATEMENTS

     This report and our other filings with the Securities and Exchange
Commission and public releases contain statements relating to our future
results, including certain projections and business trends. We believe these
statements constitute "forward-looking statements" as defined in the Private
Securities Litigation Reform Act of 1995.

     Certain risks and uncertainties may cause actual results to be materially
different from projected results contained in forward-looking statements in this
report and in our other disclosures. These risks and uncertainties include, but
are not limited to, the following:

       A Further Downturn in Market Conditions Could Affect Projected Results.
     Any unexpected material changes in oil and gas prices or other market
     trends would likely affect the forward-looking information contained in
     this report. Our estimates as to future results and industry trends make
     assumptions regarding the future prices of oil and gas and their effect on
     the demand and pricing of our products and services. In analyzing the
     market and its impact on us for the remainder of 1999 and into 2000, we
     have made the following assumptions:



                                       31
<PAGE>   33

     o   The recent increase in the price of oil will result in modest
         improvements on our businesses in the fourth quarter of 1999 and
         continue to improve through 2000, with the strongest improvements
         expected to incur in the second half of 2000.
     o   Oil prices will average around $20 per barrel for 2000.
     o   Average natural gas prices for 2000 will remain at or near their
         current levels.
     o   World demand for oil will be up only marginally or flat.
     o   Drilling activity will increase slightly beyond normal demand as oil
         companies seek to replace and produce reserves that were not replaced
         or produced in 1999.
     o   North American and international rig counts will improve, with
         increases in the international rig count following the North American
         rig count increase by around six months. In 2000, we expect the average
         rig count for North America to be around 1,040 and the international
         rig count to average around 629.
     o   Pricing for many of our products and services will continue to be
         subject to pricing pressures due to industry consolidations and
         competition as the industry recovers.
     o   Our completion and downhole services business will begin to experience
         slight improvements in the fourth quarter.
     o   Demand for compression services will remain relatively flat for the
         remainder of the year with some pricing pressure.
     o   Future growth in the industry will be dependent on technological
         advances that can reduce the costs of exploration and production, and
         technological improvements in tools used for re-entry, thru-tubing and
         extended reach drilling as well as artificial lift technologies will be
         important to our future.

       These assumptions are based on various macroeconomic factors, and actual
     market conditions could vary materially from those assumed.

       A Continuation of the Low Rig Count Could Adversely Affect the Demand for
     Our Products and Services. Our operations were materially affected by the
     decline in the rig count during 1998 and 1999 to date. Although the North
     American rig count has improved slightly from its historical low earlier
     this year, a further decline in the North American and international rig
     counts would adversely affect our results. Our forward-looking statements
     regarding our drilling products assume an improvement in the rig count in
     2000 and that there will not be any further material declines in the
     worldwide rig count, in particular the domestic rig count.

       Projected Cost Savings Could Be Insufficient. During 1998 and 1999 to
     date, we implemented a number of programs intended to reduce costs and
     align our cost structure with the current market environment. Our
     forward-looking statements regarding cost savings and their impact on our
     business assume these measures will generate the savings expected. However,
     if the markets continue to decline, additional actions may be necessary to
     achieve the desired savings.

       Grant Spinoff. We are currently proposing a spinoff of our Grant Prideco
     drilling products business. The spinoff of this business is subject to the
     receipt of a favorable private letter ruling from the Internal Revenue
     Service confirming that the spinoff will be generally tax free to us and
     our shareholders. There can be no assurance that a spinoff of the business
     will occur or the specific timing thereof.

       Integration of Acquisitions. During the last year, we have consummated
     various acquisitions of product lines and businesses. The success of these
     acquisitions will be dependent on our ability to integrate these product
     lines and businesses with our existing businesses and eliminate duplicative
     costs. We have incurred various duplicative costs with respect to the
     operations of companies and businesses acquired by us during 1999 pending
     the integration of the acquired businesses with our businesses. Revenue and
     income benefits from the acquisitions have also been delayed due to the
     current adverse market conditions. Our forward-looking statements assume
     the successful integration of the acquired businesses and their
     contribution to our income during 2000. Integration of acquisitions is
     something that cannot occur overnight and is something that requires
     constant effort at the local level to be successful. Accordingly, there can
     be no assurance as to the ultimate success of our integration efforts.

       Weatherford's Success is Dependent upon Technological Advances. Our
     ability to succeed with our long-term growth strategy is dependent on the
     technological competitiveness of our product and service offerings. A
     central aspect of our growth strategy is to enhance the technology of our
     products and services, to expand the markets for many of our products
     through the leverage of our worldwide infrastructure and to enter new


                                       32
<PAGE>   34

     markets and expand in existing markets with technologically advanced
     value-added products. Our forward-looking statements have assumed gradual
     growth from these new products and services during 2000.

       Unexpected Year 2000 Problems Could Have an Adverse Financial Impact. We
     have not fully determined the impact of Year 2000 on our systems and
     products. It is possible that unexpected problems associated with the Year
     2000 could arise during the implementation of our Year 2000 program that
     could have a material adverse effect on our business, financial condition
     and results of operations. We are currently in the testing phase of our
     Year 2000 program and expect it to be completed by the end of November
     1999.

       Economic Downturn Could Adversely Affect Demand for Products and
     Services. The economic downturn that began in Asia in 1997 affected the
     economies in other regions of the world, including South America and the
     former Soviet Union, and contributed to the decline in the price of oil and
     the level of drilling activity. Although the economy in the United States
     also has experienced one of its longest periods of growth in recent
     history, the continued strength of the United States economy cannot be
     assured. If the United States or European economies were to begin to
     decline or if the economies of South America or Asia were to experience
     further material problems, the demand and price for oil and gas and our
     products and services could again adversely affect our revenues and income.
     We have assumed that a worldwide recession or a material downturn in the
     United States economy will not occur.

       Currency Fluctuations Could Have a Material Adverse Financial Impact. A
     material decline in currency rates in our markets could affect our future
     results as well as affect the carrying values of our assets. World
     currencies have been subject to much volatility. Our forward-looking
     statements assume no material impact from changes in currencies because our
     financial position is generally dollar based or hedged. For those revenues
     denominated in local currency the effect of foreign currency fluctuations
     is largely mitigated because local expenses are denominated in the same
     currency.

       Changes in Global Trade Policies Could Adversely Impact Operations.
     Changes in global trade policies in our markets could impact our operations
     in these markets. We have assumed that there will be no material changes in
     global trading policies.

       Unexpected Litigation and Legal Disputes Could Have a Material Adverse
     Financial Impact. If we experience unexpected litigation or unexpected
     results in our existing litigation having a material effect on results, the
     accuracy of the forward-looking statements would be affected. Our
     forward-looking statements assume that there will be no such unexpected
     litigation or results.

     Finally, our future results will depend upon various other risks and
uncertainties, including, but not limited to, those detailed in our other
filings with the Securities and Exchange Commission. For additional information
regarding risks and uncertainties, see our other current year filings with the
Commission under the Securities Exchange Act of 1934, as amended, and the
Securities Act of 1933, as amended. We will generally update our assumptions in
our filings as circumstances require.

issued by us in the above transactions were issued in transactions not involving
a public offering and were exempt from registration pursuant to Section 4(2) of
the Securities Act of 1933. The issuance by us of our shares in the Dailey
International bankruptcy was exempt from registration under the Securities Act
of 1933 pursuant to Section 1145 of the United States Bankruptcy Code.

                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT (this "Agreement") is made and entered
into as of August 25, 1999, among the shareholders of Petro-Drive Inc., a
Louisiana corporation (the "Company"), listed on the signature pages hereto
(collectively, the "Shareholders"), Grant Prideco, Inc., a Delaware corporation
(the "Buyer"), and Weatherford International, Inc., a Delaware corporation
("Weatherford").


                              W I T N E S S E T H :

         WHEREAS, the Shareholders desire to transfer to the Buyer all of the
outstanding shares of capital stock (the "Shares") of the Company and the Buyer
desires to acquire the Shares, all upon the terms and subject to the conditions
set forth herein; and

         WHEREAS, the parties hereto desire to set forth certain
representations, warranties and agreements, all as more fully set forth below;

         NOW, THEREFORE, in consideration of the premises and the respective
covenants and agreements contained herein, the parties hereto agree as follows:


                                    ARTICLE 1

                                PURCHASE AND SALE

         1.1 Sale of Shares. On the Closing Date, upon the terms and subject to
the conditions contained herein, the Shareholders shall transfer, sell, assign
and convey to the Buyer, and the Buyer shall purchase from the Shareholders, the
Shares free and clear of all Liens (as defined in Section 10.32).

         1.2 Closing. Subject to the conditions set forth in this Agreement, the
Closing shall take place at the offices of Weatherford, located at 515 Post Oak
Blvd., Suite 600, Houston, Texas, at 9:00 a.m. on August 25, 1999, or at such
other time, date and place as the parties hereto shall mutually agree upon in
writing (the "Closing Date"). Failure to consummate the transactions
contemplated hereby on such date shall not result in a termination of this
Agreement or relieve any party hereto of any obligation hereunder. Title to,
ownership of and control over the Shares shall pass to the Buyer at the Closing.

         1.3 Purchase Price. On the Closing Date, in consideration of the
transfer to Buyer of the Shares, Weatherford shall issue to the Shareholders (in
the amounts set forth on Section 1.3 of the Disclosure Schedule) the Weatherford
Shares (as defined in Section 10.56) in payment of the purchase price (the
"Purchase Price"); provided, however, that an aggregate of 82,189 of the
Weatherford Shares (the "Escrowed Shares") shall be held in escrow by
Weatherford in accordance with Section 1.8.

         1.4 Purchase Price Adjustment.

                 (a) The Buyer shall, within 60 calendar days after the Closing
Date, prepare or cause to be prepared a balance sheet of the Company as of the
Closing Date (the "Closing Date Balance Sheet") and shall deliver such Closing
Date Balance Sheet to the Shareholder Representative (as defined in Section
11.1). The Buyer shall provide the Shareholder Representative with access to
copies of all work papers and other relevant documents to verify the entries
contained in the Closing Date Balance Sheet. The Closing Date Balance Sheet
shall be prepared in accordance with GAAP (as defined in Section 10.26). The
Shareholder


<PAGE>   7

Representative shall have a period of 15 calendar days after delivery to him of
the Closing Date Balance Sheet to review it and make any objections in writing
to the Buyer. If written objections to the Closing Date Balance Sheet are
delivered to the Buyer within such 15-day period, then the Buyer and the
Shareholder Representative shall attempt to resolve the matter or matters in
dispute. If no written objections are made within the time period provided
above, the Closing Date Balance Sheet shall become final and binding on the
parties hereto and the Purchase Price shall be adjusted as described in clause
(c) below.

                 (b) If disputes with respect to the Closing Date Balance Sheet
cannot be resolved by the Buyer and the Shareholder Representative within 15
calendar days after the delivery of the objections to the Closing Date Balance
Sheet, then either party, with notice to the other party, may submit the
specific matters in dispute to Ernst & Young LLP or such other recognized
independent accounting firm as may be approved by the Buyer and the Shareholder
Representative, which firm shall render its opinion as to such matters. Based on
such opinion, such accounting firm will then send to the Buyer and the
Shareholder Representative its determination in writing on the specific matters
in dispute, including any resulting revisions to the Closing Date Balance Sheet.
The Closing Date Balance Sheet, including revisions, if any, made by such
accounting firm, shall then become final and binding on the parties hereto and
the Purchase Price shall be adjusted as described in clause (c) below. The fees
and other costs charged by the independent accounting firm shall be borne by the
Buyer, on the one hand, and the Shareholders (in proportion of their Share
ownership), on the other hand, equally.

                 (c) At the time the Closing Date Balance Sheet becomes final
and binding on the parties hereto, the Purchase Price will be:

                            (i) reduced by the amount, if any, by which the
              Target Working Capital (as defined in Section 10.51) exceeds the
              Closing Date Working Capital (as defined in Section 10.11);

                            (ii) increased by the amount, if any, by which the
              Closing Date Working Capital exceeds the Target Working Capital;

                            (iii) reduced by the amount, if any, by which the
              Closing Date Debt (as defined in Section 10.10) exceeds the Target
              Debt (as defined in Section 10.50);

                            (iv) increased by the amount, if any, by which the
              Target Debt exceeds the Closing Date Debt; and

                            (v) reduced by $122,000, which represents the amount
              to replace or repair the 18-ton stiff leg crane.

If the foregoing adjustments result in a net decrease in the Purchase Price, the
Shareholders shall, within five days of the date that the Closing Date Balance
Sheet becomes final and binding on the parties hereto, transfer to the Buyer, in
the same proportions as the Shareholders received the Weatherford Shares, the
number of shares of Common Stock equal to the amount of such difference, as
determined in clause (d) below. If the foregoing adjustments result in a net
increase in the Purchase Price, the Buyer shall, within five days of the date
that the Closing Date Balance Sheet becomes final and binding on the parties
hereto, cause Weatherford to issue to the Shareholders, in the same proportions
as the Shareholders received the Weatherford Shares, the number of shares of
Common Stock equal to the amount of such difference, as determined in clause (d)
below.

                 (d) Any adjustments made pursuant to this Section 1.4 shall be
made in shares of Common Stock or cash, at the option of the payor. The number
of shares of Common Stock that may be issued



                                       2
<PAGE>   8

by Weatherford or transferred by the Shareholders, as the case may be, shall be
equal to the amount of the adjustment, divided by the Average Closing Price (as
defined in Section 10.3). If the Shareholders decide to use shares of Common
Stock to pay any adjustment under this Section 1.4, such payment shall be made
first from the Escrowed Shares and then, as necessary, from the other
Weatherford Shares issued to the Shareholders at Closing. Any payments made
pursuant to this Section 1.4 shall be deemed to be adjustments to the Purchase
Price.

                 (e) For purposes of preparing the Closing Date Balance Sheet,
there shall be no (i) increases in the carrying value of any assets of the
Company by virtue of any adjustments made after March 31, 1999, or (ii)
increases in assets of the Company due to the recognition of any non-cash
increase after March 31, 1999, other than in connection with sales and
dispositions of inventory in the ordinary course of business.

         1.5 Liabilities Assumed by the Shareholders. Effective immediately
prior to the Closing, the Shareholders shall assume all of the Retained
Liabilities (as defined in Section 10.41).

         1.6 Weatherford Share Adjustments. If any of the Shareholders sells any
Weatherford Shares during the period commencing on the first anniversary of the
Closing Date and ending on the second anniversary of the Closing Date in a bona
fide open market transaction to a non-Affiliate of any of the Shareholders (a
"Resale") at a gross sales price per share that is less than $36.50 (the "Target
Price"), Weatherford and the Buyer agree to issue to such Shareholder the number
of shares of Common Stock equal to (i) the number of Weatherford Shares sold in
the Resale multiplied by the difference between the Target Price and the gross
sales price per share received in the Resale, divided by (ii) the gross sales
price per share at Resale (such issuance referred to as an "Additional
Payment"); provided, however, that Weatherford may, in its sole discretion,
elect to make any Additional Payment in cash. On the third Business Day
following the receipt by Weatherford of adequate documentation of a Resale,
including a copy of the broker's transaction report for the Resale, which shall
include the gross sales price per Weatherford Share sold in the Resale, an
Additional Payment shall be made by the Buyer or Weatherford to such
Shareholder. Notwithstanding the foregoing, if for any period of 10 consecutive
trading days subsequent to the first anniversary of the Closing Date, the
closing sales price of the Common Stock, as reported by the New York Stock
Exchange, is greater than the Target Price, Weatherford's and the Buyer's
obligations under this Section 1.6 shall terminate.

         1.7 Adjustments for Changes in Capitalization. For purposes of this
Article 1, references to the Common Stock, Escrowed Shares and Weatherford
Shares shall include any stock, securities, cash or other property that may be
received by a stockholder who is issued a share of Common Stock on the Closing
Date in respect of such share and all references to the market value of the
Common Stock as of any date shall mean the sum of the market value of Common
Stock and such other stock, securities, cash or other property that may be
received by a holder of Common Stock in respect of a share of Common Stock. In
the event a change in capitalization in accordance with the immediately
preceding sentence includes the issuance or distribution by Weatherford of
stock, securities, cash or other property, then for purposes of determining
whether a Resale is for an amount less than the Target Price, the "gross sales
price per share" shall be calculated by adding the sales price received for the
portion of the Weatherford Shares actually sold to the value of the portion of
the Weatherford Shares retained. The determination of the value of any security
shall be based on the closing sale price of that security on the principal stock
exchange on which it is listed if that security is traded on a national
securities exchange. If the principal market in which a security is traded is an
automated trading system, such as NASDAQ, the market value on any day shall be
the average of the high and low bid price for that security on that day. If any
other security or property is received, its value shall be determined by
agreement by a nationally recognized investment banking firm selected in good
faith by Weatherford. In the event of a reclassification of the Common Stock
into a greater or lesser number of shares of Common Stock, all



                                       3
<PAGE>   9

references to numbers of shares of Common Stock and all market prices (including
Target Price) for the Common Stock shall be appropriately adjusted to reflect
such reclassification.

         1.8 Escrowed Shares. Subject to Section 1.4 and Article 7, the Escrowed
Shares shall be issued and outstanding for all purposes and held in escrow by
Weatherford until the later to occur of (i) three years after the date of the
filing of the Company's 1999 Tax returns and (ii) the completion and resolution
of any Tax audits involving the Company (the "Termination Date"); provided,
however, that if on the Termination Date any claims for indemnification for
Buyer Losses have not been resolved or paid in full, such Termination Date shall
be extended and any or all of the Escrowed Shares may be held in escrow by
Weatherford for so long as any of such claims for indemnification for Buyer
Losses have not been resolved or paid in full. Any dividends or distributions
paid or payable with respect to the Escrowed Shares shall also be deemed to
constitute Escrowed Shares and shall be subject to the terms of this Section
1.8. Following one year after the date hereof, if any Shareholder desires to
sell any of such Shareholder's Escrowed Shares, Weatherford will release such
shares provided that the Shareholder deposits with Weatherford or the Buyer an
aggregate amount in cash equal to the number of Escrowed Shares withdrawn
multiplied by $36.50 per share. To the extent the Escrowed Shares consist of
cash, the Buyer or Weatherford can satisfy their rights to receive payments
under Section 7.4 by withdrawing cash or shares or any combination thereof. Such
cash deposited with Weatherford or the Buyer, including any interest earned
thereon, shall be held in escrow and be deemed to constitute Escrowed Shares for
purposes of this Agreement. All cash deposited with Weatherford or the Buyer
shall earn interest at the same interest rate that Weatherford or the Buyer
earns on its money investment account. Subject to the foregoing, Weatherford
shall deliver to the Shareholders (in such proportions as the Shareholders
received the Weatherford Shares) the Escrowed Shares, if any, remaining on the
Termination Date.


                                    ARTICLE 2

               REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERS

         The Shareholders hereby represent and warrant to the Buyer and
Weatherford as follows:

         2.1 Organizational Matters.

                 (a) The Company is a corporation, duly organized, validly
existing and in good standing under the laws of the State of Louisiana. The
Company is duly authorized, qualified and licensed and has all requisite power
and authority under all applicable laws, ordinances and orders of public
authorities to own, operate and lease its properties and assets and to carry on
its business in the places and in the manner currently conducted. The Company is
duly qualified to transact business as a foreign corporation and is in good
standing in the jurisdictions specified in Section 2.1(a) of the Disclosure
Schedule and there is no other jurisdiction in which the nature and extent of
the business conducted by the Company or the character of its assets makes such
qualification necessary. The Company does not do business in any state, country
or commonwealth under any name other than "Petro-Drive". The Company does not
have any Subsidiaries.

                 (b) The items set forth in Section 2.1(b) of the Disclosure
Schedule are true, correct and complete copies of the Articles of Incorporation
and Bylaws of the Company, as amended and in full force and effect. The
authorized capital of the Company consists of 5,000,000 shares of common stock,
no par value, of which 206,888 shares are issued and outstanding. All issued and
outstanding shares of capital stock of the Company are owned of record by the
Shareholders, free and clear of all Liens, in the amounts set forth in Section
2.1(b) of the Disclosure Schedule. The Shares have been duly authorized and
validly issued and are fully paid and non-assessable and were not issued in
violation of any preemptive, preferential purchase or other



                                       4
<PAGE>   10

similar rights of any Person. There are no outstanding options, warrants,
convertible securities, calls, rights, commitments, preemptive rights,
agreements, arrangements or understandings of any character obligating the
Company (i) to issue, deliver or sell, or cause to be issued, delivered or sold,
additional shares in the capital of the Company or any securities or obligations
convertible into or exchangeable for such shares or (ii) to grant, extend or
enter into any such option, warrant, convertible security, call, right,
commitment, preemptive right, agreement, arrangement or understanding. The
Shareholders have the absolute right to transfer the Shares to the Buyer. Upon
the purchase of the Shares as contemplated by this Agreement, the Buyer will
obtain good and valid title to the Shares, free and clear of all Liens.

         2.2 Validity of Agreement and Conflict with Other Instruments.

                 (a) Each of the Shareholders has the requisite legal capacity,
power and authority to enter into this Agreement, to consummate the transactions
contemplated hereunder and to perform his or its obligations under this
Agreement. This Agreement has been duly authorized, executed and delivered by
each of the Shareholders and is a legal, valid and binding obligation of such
Shareholder, enforceable against such Shareholder in accordance with its terms,
except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws from time to time in effect that
affect creditors' rights generally and by legal and equitable limitations on the
availability of specific remedies. The Shareholders have not entered into any
other agreement whereby the Shares will be sold, assigned or otherwise
transferred to another Person.

                 (b) The execution, delivery and performance of this Agreement
by the Shareholders and the consummation of the transactions contemplated hereby
(i) do not violate any provision of the Articles of Incorporation or Bylaws of
the Company, or any law, statute, ordinance, regulation, judgment, writ,
injunction, rule, decree, order or any other restriction of any kind or
character applicable to the Shareholders or the Company or any of their
respective properties or assets, (ii) do not conflict with, or result in any
breach of, or default or loss of any right under (or an event or circumstance
that, with notice or the lapse of time, or both, may result in a default), or
the creation of a Lien pursuant to, or cause or permit the acceleration prior to
maturity of any amounts owing under, any indenture, mortgage, deed of trust,
lease or other agreement to which any of the Shareholders or the Company is a
party or to which any of their respective assets are subject, (iii) do not
require the consent, approval, clearance, waiver, order or authorization of any
Person (as defined in Section 10.37) or Governmental Entity (as defined in
Section 10.27) that has not been obtained and (iv) conflict with, constitute a
breach, violation or termination of any provision of any agreement or contract,
whether written or otherwise, to which the Company is a party or by which it is
bound.

                 (c) Except as set forth in Section 2.2(c) of the Disclosure
Schedule, the execution, delivery and performance of this Agreement by the
Shareholders will not result in the loss of any license, franchise or permit
possessed by the Company or give a right of acceleration or termination to any
party to any agreement or other instrument to which the Company is a party or by
which any of its assets are bound, or the loss of any right or benefit under
such agreement or instrument.

         2.3 Approvals, Licenses and Authorizations.

                            (i) No order, license, consent, waiver,
authorization or approval of, or exemption by, or the giving of notice to, or
the registration with, or the taking of any other action in respect of, any
Person not a party to this Agreement, including any Governmental Entity, and no
filing, recording, publication or registration in any public office or any other
place is now, or under existing law in the future will be, necessary on behalf
of any of the Shareholders or the Company to authorize the execution, delivery
and performance of this Agreement or any other agreement contemplated hereby to
be executed and delivered by the Shareholders



                                       5
<PAGE>   11

and the consummation of the transactions contemplated hereby or thereby
(including, but not limited to, assignment of the Shares), or to effect the
legality, validity, binding effect or enforceability thereof.

                 (a) All licenses, permits, concessions, warrants, franchises
and other governmental authorizations and approvals of all Governmental Entities
required or necessary for the Company to carry on its business in the places and
in the manner currently conducted have been duly obtained and are in full force

                 (c) None of such Tax Returns are under audit or examination by
any foreign, federal, provincial, state or local authority and there are no
agreements, waivers or other arrangements providing for an extension of time
with respect to the assessment or collection of any Tax or deficiency of any

or other actions, proceedings, investigations or claims now pending or
threatened against the Company with respect to any Tax, or any matters under

Tax, or any claims for any additional Tax asserted by any such authority.

                 (d) All Taxes assessed and due and owing from or against the

                 (l) No special agreements, rulings or compromises have been
entered into between the Company and any foreign, federal, provincial, state or
local authority regarding the assessment or payment of Taxes.

and all claims, liabilities or obligations with respect to all fees, commissions
or expenses asserted by any Person on the basis of any act, statement, agreement

         2.15 Securities Law Matters.

                 (a) Each of the Shareholders recognizes and understands that
the Weatherford Shares to be issued to the Shareholders (the "securities") will
not, except as expressly provided in Article 4, be registered under the
Securities Act (as defined in Section 10.43), or under the securities laws of
any state (the "securities laws"). The securities are not being so registered in
reliance upon exemptions from the Securities Act and the securities laws which
are predicated, in part, on the representations, warranties and agreements of
the Shareholders contained herein.

                 (b) Each of the Shareholders represents and warrants that (i)
such Shareholder has business knowledge and experience, such experience being
based on actual participation therein, (ii) such Shareholder is capable of
evaluating the merits and risks of an investment in the Weatherford Shares and
the suitability thereof as an investment therefor, (iii) the Weatherford Shares
to be acquired by the Shareholders will be acquired solely for investment and
not with a view toward resale or redistribution in violation of the securities
laws, (iv) such Shareholder is a natural person, or a trust for the benefit of
the children of a natural person, whose residence and domicile are in the State
of Louisiana, (v) in connection with the transactions contemplated hereby, no
assurances have been made concerning the future results of the Buyer or
Weatherford or as to the value of the Weatherford Shares and (vi) each of the
Shareholders is an "accredited investor" within the meaning of Regulation D
promulgated by the Commission pursuant to the Securities Act. Each of the
Shareholders understands that neither Weatherford nor the Buyer is under any
obligation to file a registration statement or to take any other action under
the securities laws with respect to any such securities.

                 (c) Each of the Shareholders have consulted with his or her own
counsel in regard to the securities laws and are fully aware (i) of the
circumstances under which such Shareholder is required to hold the securities,
(ii) of the limitations on the transfer or disposition of the securities, (iii)
that the securities must be held indefinitely unless the transfer thereof is
registered under the securities laws or an exemption from registration is
available and (iv) that no exemption from registration is likely to become
available for at least one year from the date of acquisition of the securities.
Each of the Shareholders have been advised by his or her counsel as to the
provisions of Rules 144 and 145 as promulgated by the Commission under the
Securities Act and have been advised of the applicable limitations thereof. Each
of the Shareholders acknowledge that Weatherford and the Buyer are relying upon
the truth and accuracy of the representations and warranties in this Section
2.15 by each of the Shareholders in consummating the transactions contemplated
by this Agreement without registering the securities under the securities laws.

                 (d) Each of the Shareholders has been furnished with the SEC
Documents. Each of the Shareholders has been furnished with a summary
description of the terms of this Agreement, the Weatherford Shares and
Weatherford, and the Buyer and Weatherford have made available to each of the

terms and conditions of the transactions contemplated by this Agreement and to
obtain any additional information which they possess or could reasonably acquire
for the purpose of verifying the accuracy of information furnished to the
Shareholders as set forth herein or for the purpose of considering the
transactions contemplated hereby. Weatherford has offered to make available to
each of the Shareholders upon request at any time all exhibits filed by
Weatherford with the Commission as part of any of the reports filed therewith.

<PAGE>   21

                 (e) Each of the Shareholders agree that the certificates
representing the Weatherford Shares will be imprinted with the following legend,
the terms of which are specifically agreed to:

         THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
         INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, OR THE SECURITIES LAWS OF ANY STATE, IN RELIANCE UPON EXEMPTIONS
         FROM REGISTRATION REQUIREMENTS. WITHOUT SUCH REGISTRATION, SUCH SHARES
         MAY NOT BE SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED, EXCEPT
         UPON DELIVERY TO THE COMPANY OF AN OPINION OF COUNSEL REASONABLY
         SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED FOR SUCH
         SALE, PLEDGE, HYPOTHECATION OR TRANSFER OR THE SUBMISSION TO THE
         COMPANY OF SUCH OTHER EVIDENCE AS MAY BE SATISFACTORY TO THE COMPANY TO
         THE EFFECT THAT SUCH SALE, PLEDGE, HYPOTHECATION OR TRANSFER SHALL
         NOT BE IN VIOLATION OF THE SECURITIES ACT OF 1933 OR APPLICABLE STATE
         SECURITIES LAWS OR ANY RULE OR REGULATION PROMULGATED THEREUNDER.

Each of the Shareholders understands and agrees that appropriate stop transfer
notations will be placed in the records of Weatherford and with its transfer
agents in respect of the securities which are to be issued to the Shareholders.
Weatherford agrees that any Weatherford Shares sold pursuant to an effective
registration statement shall have the above legend removed to permit the closing
of the sale within three Business Days of written notice of the sale and
certification by the selling Shareholder that the sale was made pursuant to the
plan of distribution described in the registration statement and the prospectus
delivery requirements under the Securities Act were fully complied with in
connection with the sale.

           REPRESENTATIONS AND WARRANTIES OF THE BUYER AND WEATHERFORD

         The Buyer and Weatherford jointly and severally represent and warrant

corporation validly existing and in good standing under the laws of Delaware.
Each of Weatherford and the Buyer has all requisite power and authority to enter
into this Agreement and to perform its obligations under this Agreement. This
Agreement has been duly authorized, executed and delivered by each of
Weatherford and the Buyer and is a legal, valid and binding obligation of each
of Weatherford and the Buyer, enforceable in accordance with its terms, except
as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws from time to time in effect that
affect creditors' rights generally and by legal and equitable limitations on the
availability of specific remedies. The execution and delivery of this Agreement
by each of Weatherford and the Buyer have been duly authorized by all necessary
corporate action and the consummation of the transactions contemplated hereby by
Weatherford and the Buyer will not violate any provision of, or constitute a
default under, any contract or other agreement to which either of Weatherford or
the Buyer is a party or by which it is bound, or conflict with its
organizational documents, other than violations, defaults or conflicts that
would not materially and adversely affect the ability of Weatherford or the
Buyer to consummate the transactions provided for in this Agreement.

         3.2 Approvals, Licenses and Authorizations. Except as otherwise
provided in this Agreement, no order, license, consent, waiver, authorization or
approval of, or exemption by, or the giving of notice to, or the registration
with, or the taking of any other action in respect of, any Person not a party to
this Agreement, including any Governmental Entity, and no filing, recording,
publication or registration in any public office or any other place is now, or
under existing law in the future will be, necessary on behalf of the Buyer or
Weatherford to authorize its execution, delivery and performance of this
Agreement or any other agreement contemplated hereby to be executed and
delivered by the Buyer or Weatherford and the consummation by the Buyer and
Weatherford of the transactions contemplated hereby or thereby, or to effect the
legality, validity, binding effect or enforceability thereof.

         3.3 Finder's Fees. Neither the Buyer, Weatherford nor any of their
respective Affiliates has employed or retained any investment banker, broker,
agent, finder or other party, or incurred any obligation for brokerage fees,
finder's fees or commissions, with respect to the transactions contemplated by
this Agreement, or otherwise dealt with anyone purporting to act in the capacity
of a finder or broker with respect thereto whereby any party hereto may be
obligated to pay such a fee or a commission. The Buyer and Weatherford, jointly
and severally, agree to indemnify and hold the Shareholders and their Affiliates
harmless from and against any and all claims, liabilities or obligations with
respect to all fees, commissions or expenses asserted by any Person on the basis
of any act, statement, agreement or commitment alleged to have been made by the
Buyer or any Affiliate of the Buyer with respect to any such fee, commission or
expense.

         3.4 Authorization for the Weatherford Shares. Weatherford has taken, or
will have taken prior to Closing, all necessary action to permit it to issue the
Weatherford Shares. The Weatherford Shares issued pursuant to the terms of this
Agreement will be validly issued, fully paid and nonassessable and not subject
to preemptive rights. The Weatherford Shares will be listed on the New York
Stock Exchange.

         3.5 SEC Documents. Weatherford has made available to the Shareholders
all of the SEC Documents (as defined in Section 10.42). The SEC Documents
represent each report filed by Weatherford with the Commission since March 30,
1999. As of their respective dates, the SEC Documents (i) were



                                       17
<PAGE>   23

prepared in all material respects in accordance with the applicable requirements
of the Securities Exchange Act of 1934, as amended, and the rules and
regulations thereunder applicable to such documents and (ii) did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements made therein, in light of
the circumstances under which they were made, not misleading except for such
statements, if any, as have been modified by subsequent filing with the
Commission prior to the date hereof. The consolidated financial statements of
Weatherford included in the SEC Documents comply as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the Commission with respect thereto, have been prepared in
accordance with GAAP (except as may be indicated in the notes thereto) and
fairly present the consolidated financial position of Weatherford and its
consolidated Subsidiaries (as defined in Section 10.49) as of the dates thereof
and the consolidated results of their operations and cash flows for the periods
then ended. Since December 31, 1998, other than as discussed in the SEC
Documents, there has been no material adverse change in the business of
Weatherford and its Subsidiaries, taken as a whole.

document, including the Disclosure Schedule, delivered in connection with this
Agreement. The Shareholders will cooperate with the Buyer and its employees,

         4.3 Negotiation with Others. The Shareholders agree that from the date
hereof until the Closing Date or the termination of this Agreement pursuant to
Article 9, none of the Shareholders or any of their respective Affiliates,

<PAGE>   26

respect to a merger, consolidation, asset purchase, stock purchase or any
similar transaction involving the Company or any material portion of its assets
or property with any such Person. During such period, the Shareholders will
immediately notify the Buyer regarding any such contact between the
Shareholders, any Affiliate or any of their representatives and any Person
regarding any such offer or proposal or any related inquiry and shall return
without discussion all offers or proposals regarding any such transaction
involving the Company.

         4.4 Information. During the period from the date of this Agreement to
the Closing Date, the Buyer, Weatherford and the Shareholders will promptly
inform each other in writing of any claim, action or proceeding commenced

         4.5 Delivery of Documents. The Shareholders shall deliver to the Buyer
at or before the Closing all Documents and Other Papers (as defined in Section
10.17) relating to the Company that are in the Shareholders' possession or
control, including, without limitation, all files relating to the Financial
Statements, computer disks reflecting any books or records, documents or other
papers, or other information or data relating to the operation of the Company
stored on any electronic media, including computers. For a period of three years
after the Closing Date, the Buyer agrees to provide the Shareholders with access
to such Documents and Other Papers to the extent required for tax, financial
accounting or legal purposes on a reasonable basis during normal business hours
and to permit copies to be made of such Documents and Other Papers as may be
reasonably needed. All such Documents and Other Papers shall be maintained by
the Shareholders in confidence except to the extent required to be disclosed
under law or in furtherance of any defense by the Shareholders or any Affiliate
of the Shareholders to any action, suit or proceeding against the Shareholders
or any Affiliate of the Shareholders; provided, however, the Buyer shall be
advised of any such proposed disclosure in advance and be entitled to seek a
limitation on the use of such information and scope of such disclosure.

         4.6 Further Assurances. Each of the Shareholders shall execute,
acknowledge and deliver, or cause to be executed, acknowledged and delivered, to
the Buyer such bills of sale, assignments (including but not limited to
assignments of leases) and other instruments of transfer, assignment and
conveyance, in form and substance satisfactory to counsel for the Buyer, as
shall be necessary to vest in the Buyer all the right, title and interest in and
to the Shares free and clear of all Liens (other than those Liens created or
suffered by the Buyer and restrictions on sales of Shares under applicable
securities laws) and shall use his or its best efforts to cause to be taken such
other action as the Buyer reasonably may require to more effectively implement
and carry into effect the transactions contemplated by this Agreement. For the
assignment of the Shares from the Shareholders to the Buyer, each of the
Shareholders is obligated at all times without delay in the legal or contractual
required form to carry out all necessary acts and to deliver all legally
required declarations. Weatherford shall take all action necessary to perform,

Agreement.

         4.7 Nondisclosure of Proprietary Information.

                 (a) Each of the Shareholders agrees that, from and after the
Closing, such Shareholder and such Shareholder's Affiliates shall (i) hold in
confidence and will not directly or indirectly at any time reveal, report,
publish, disclose or transfer to any Person other than the Buyer any of the
Proprietary Information that is not generally known to the public or utilize any
of the Proprietary Information for any purpose and (ii) not for a period of five
years solicit or hire any employees of the Company who are currently employed or
may be employed as of the Closing by the Company.



                                       21
<PAGE>   27

                 (b) The Shareholders acknowledge that all documents and objects
containing or reflecting any Proprietary Information, whether developed by the
Company, or by someone else for the Company or any of its Affiliates, will after
the Closing become the exclusive property of the Buyer and be delivered to the
Buyer.

                 (c) Because of the unique nature of the Proprietary
Information, the Shareholders understand and agree that the breach or
anticipated breach of the obligations under this Section 4.7 will result in
immediate and irreparable harm and injury to the Buyer and its Affiliates, for
which it will not have an adequate remedy at law, and that the Buyer and its
Affiliates and their successors and assigns shall be entitled to relief in
equity to enjoin such breach or anticipated breach and to seek any and all other
legal and equitable remedies to which they may be entitled.

         4.8 Covenant Not to Compete With the Business. Each Shareholder agrees
that, effective as of the Closing Date and for a period of five years
thereafter, neither such Shareholder nor any of its Affiliates thereof shall,
without the consent of the Buyer, directly or indirectly, design, develop,
market, produce, manufacture, rent, distribute, repair, provide or sell any
hammer (hydraulic, diesel, steam or otherwise), welding, crane or tubular
products or related services in any geographic location in the world or, except
for the benefit of the Buyer and its Affiliates, assist any Person to do the
same. Each Shareholder acknowledges that a remedy at law for any breach or
attempted breach of this Section 4.8 will be inadequate and further agrees that
any breach of this Section 4.8 will result in irreparable harm to the Company
and the Buyer, and, accordingly, the Buyer, shall, in addition to any other
remedy that may be available to it, be entitled to specific performance and
injunctive and other equitable relief in case of any such breach or attempted
breach. Each of Shareholders acknowledges that this covenant not to compete is
being provided as an inducement to the Buyer to acquire the Shares and that this
Section 4.8 contains reasonable limitations as to time, geographical area and
scope of activity to be restrained that do not impose a greater restraint than
is necessary to protect the goodwill or other business interest of the Buyer.
Whenever possible, each provision of this Section 4.8 shall be interpreted in
such a manner as to be effective and valid under applicable law but if any
provision of this Section 4.8 shall be prohibited by or invalid under applicable
law, such provision shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remaining provisions of this Section 4.8.
If any provision of this Section 4.8 shall, for any reason, be judged by any
court of competent jurisdiction to be invalid or unenforceable, such judgment
shall not affect, impair or invalidate the remainder of this Section 4.8 but
shall be confined in its operation to the provision of this Section 4.8 directly
involved in the controversy in which such judgment shall have been rendered. In
the event that the provisions of this Section 4.8 should ever be deemed to
exceed the time or geographic limitations permitted by applicable laws, then
such provision shall be reformed to the maximum time or geographic limitations
permitted by applicable law.

         4.9 Use of Corporate Name. All uses of the corporate names
"Petro-Drive" and "Hydrodrive" or any derivations thereof are being transferred
to the Buyer hereunder. Each of the Shareholders agrees not to take any action
that could reasonably be expected to adversely affect the Buyer's right to the
names "Petro-Drive" and "Hydrodrive" or cause confusion with respect to the
Buyer's use of such names. All goodwill with respect to the use of the names
"Petro-Drive" or "Hydrodrive" will inure to the benefit of the Buyer, and none
of the Shareholders will have any rights to sue or recover against any Person
with respect to the use of such names.

                                    ARTICLE 7

                                 INDEMNIFICATION

         7.1 Indemnification by the Shareholders. Charles Milam, Wesley B.
Manuel and Thomas Mautner (the "Indemnifying Shareholders") in respective shares
of 80%, 10% and 10% of the total obligations hereunder, agree to indemnify,
defend and hold the Buyer, Weatherford, each of their respective Affiliates and
each of their respective officers, directors, employees, agents, stockholders
and controlling Persons and their respective successors and assigns, harmless
from and against and in respect of Damages (as defined in Section 10.14)
actually suffered, incurred or realized by such party (collectively, "Buyer
Losses"), arising out of or resulting from or relating to:

                 (a) any misrepresentation, breach of representation or
warranty or breach of any covenant or agreement made or undertaken by the
Shareholders in this Agreement or any misrepresentation or omission from any
other agreement, certificate, exhibit or writing delivered to the Buyer or
Weatherford pursuant to this Agreement, including the Disclosure Schedule; or

                 (b) any Retained Liability.

For purposes of determining the Buyer's and Weatherford's right to
indemnification for a misrepresentation or breach of warranty made by the
Shareholders in this Agreement, all such representations and warranties that
have been made subject to a materiality qualification shall be deemed to have
been made without that qualification.

         7.2 Indemnification by the Buyer and Weatherford. Except as otherwise
limited by this Article 7 and Article 8 hereof, the Buyer and Weatherford
jointly and severally agree to indemnify, defend and hold the Shareholders and
their successors and assigns harmless from and against and in respect of Damages
actually suffered, incurred or realized by such party (collectively,
"Shareholders Losses"), arising out of or resulting from (a) any
misrepresentation, breach of warranty or breach of any covenant or agreement
made or undertaken by the Buyer or Weatherford in this Agreement or any
misrepresentation in or omission from any other agreement, certificate, Exhibit
or writing delivered to the Shareholders pursuant to this Agreement or (b) any
liabilities of the Company based upon actions, omissions or events occurring
after Closing, excluding all Retained Liabilities and any liabilities arising
out of or resulting from any misrepresentation, breach or representation or
warranty or breach of covenant or agreement made or undertaken by any of the
Shareholders.

         7.3 Procedure. All claims for indemnification under this Article 7
shall be asserted and resolved as follows:

                 (a) An Indemnitee (as defined in Section 10.29) shall promptly
give the Indemnitor (as defined in Section 10.30) notice of any matter that an
Indemnitee has determined has given or could give rise to a right of
indemnification under this Agreement, stating the amount of the Loss, if known,
and method of computation thereof, all with reasonable particularity, and
stating with particularity the nature of such matter. Failure to provide such
notice shall not affect the right of the Indemnitee to indemnification except to
the extent such failure shall have resulted in liability to the Indemnitor that
could have been actually avoided had such notice been provided within such
required time period.

                 (b) The obligations and liabilities of an Indemnitor under this
Article 7 with respect to Losses arising from claims of any third party that are
subject to the indemnification provided for in this Article 7 ("Third Party
Claims") shall be governed by and contingent upon the following additional terms
and



                                       28
<PAGE>   34

conditions: if an Indemnitee shall receive notice of any Third Party Claim, the
Indemnitee shall give the Indemnitor prompt notice of such Third Party Claim and
the Indemnitor may, at its option, assume and control the defense of such Third
Party Claim at the Indemnitor's expense and through counsel of the Indemnitor's
choice reasonably acceptable to the Indemnitee. In the event the Indemnitor
assumes the defense against any such Third Party Claim as provided above, the
Indemnitee shall have the right to participate at its own expense in the defense
of such asserted liability, shall cooperate with the Indemnitor in such defense
and will attempt to make available on a reasonable basis to the Indemnitor all
witnesses, pertinent records, materials and information in its possession or
under its control relating thereto as is reasonably required by the Indemnitor.
In the event the Indemnitor does not elect to conduct the defense against any
such Third Party Claim, the Indemnitor shall pay all reasonable costs and
expenses of such defense as incurred and shall cooperate with the Indemnitee
(and be entitled to participate) in such defense and attempt to make available
to it on a reasonable basis all such witnesses, records, materials and
information in its possession or under its control relating thereto as is
reasonably required by the Indemnitee. Except for the settlement of a Third
Party Claim that involves the payment of money only and for which the Indemnitee
is totally indemnified by the Indemnitor, no Third Party Claim may be settled
without the written consent of the Indemnitee.

         7.4 Payment. Payment of any amounts due pursuant to this Article 7
shall be made within ten Business Days after notice is sent by the Indemnitee.
To the extent there exist any Escrowed Shares, payment for any Buyer Losses
shall first be made by the retainment by Buyer or Weatherford of Escrowed
Shares.

         7.5 Failure to Pay Indemnification. If and to the extent the Indemnitee
shall make written demand upon the Indemnitor for indemnification pursuant to
this Article 7 and the Indemnitor shall refuse or fail to pay in full within ten
Business Days of such written demand the amounts demanded pursuant hereto and in
accordance herewith, then the Indemnitee may utilize any legal or equitable
remedy to collect from the Indemnitor the amount of its Losses. Nothing
contained herein is intended to limit or constrain the Indemnitee's rights
against the Indemnitor for indemnity, the remedies herein being cumulative and
in addition to all other rights and remedies of the Indemnitee.

         7.6 Express Negligence. THE INDEMNITIES SET FORTH IN THIS ARTICLE 7 ARE
INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS
TERMS AND SCOPE THEREOF NOTWITHSTANDING THE EXPRESS NEGLIGENCE RULE OF ANY STATE
OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES
BECAUSE OF THE SIMPLE OR GROSS NEGLIGENCE (WHETHER SOLE, CONCURRENT, ACTIVE OR
PASSIVE) OR OTHER FAULT OR STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES.

         7.7 Indemnification Limitations. The Shareholders shall be liable under
Section 7.1(a) in respect of a misrepresentation or breach of warranty only if
and then only to the extent that, the aggregate amount of any Buyer Losses for
which the Buyer and Weatherford are entitled to indemnification pursuant to such
clause exceeds $50,000; provided, however, the Shareholders' liability under
Section 7.1(a) shall not be so limited if such Buyer Losses arise from a breach
of any of the representations set forth in Sections 2.1, 2.2(a), 2.4, 2.9, 2.13
or 2.15 or from a breach of any covenant or agreement set forth herein. There
shall be no limits on the Shareholders' liability (i) arising from a breach of
any of the representations set forth in Sections 2.1, 2.2(a), 2.4(c), 2.7, 2.10,
2.12, 2.13, (ii) under Section 7.1(a) with respect to breaches of covenants or
agreements or (iii) under Section 7.1(b). For a breach of any representation
other than those specifically identified in clause (i) of the preceding
sentence, the liability of the Shareholders shall be limited to the Purchase
Price, which shall be calculated as of the Closing Date after taking into
account any adjustments made pursuant to Section 1.4.



                                       29
<PAGE>   35

         7.8 Liability Adjustment. The amount which an Indemnitee shall be
entitled to receive from an Indemnitor with respect to any Indemnifiable Losses
under this Article 7 shall be net of any insurance recovery by the Indemnitee on
account of such Losses from an unaffiliated party.


                                    ARTICLE 8

                 NATURE OF STATEMENTS AND SURVIVAL OF COVENANTS,
                   REPRESENTATIONS, WARRANTIES AND AGREEMENTS

         All statements of fact contained in any written statement (including
financial statements), certificate, instrument or document delivered by or on
behalf of the Shareholders pursuant to this Agreement shall be deemed
representations and warranties of the Shareholders. The several representations
and warranties of the parties to this Agreement shall survive the Closing Date

         11.5 Specific Performance. It is specifically understood and agreed
that any breach by a party of the covenants or agreements of this Agreement is
likely to result in irreparable harm to the other party and that an action at
law for damages alone will be an inadequate remedy for such breach. Accordingly,
in addition to any other remedy that may be available to it, in the event of
breach or threatened breach by any party of the covenants or agreements of this
Agreement, including, without limitation, Section 4.8 hereof, the other party
shall be entitled to enforce the specific performance of this Agreement and to
seek both temporary and permanent injunctive relief (to the extent permitted by
law), without the necessity of providing actual damages, and such other relief
as the court may allow.

         11.6 Assignment and Successors. Except as specifically contemplated by
this Agreement, no party hereto shall assign this Agreement or any part hereof
without the prior written consent of the other party; provided, however, the
Buyer may, upon written notice to the Shareholders, assign its rights and
obligations in this Agreement to an Affiliate of the Buyer. This Agreement shall
inure to the benefit of, be binding upon and be enforceable by the parties
hereto and their respective successors and assigns.

         11.7 Entire Agreement. This Agreement, the Confidentiality Agreement
dated November 4, 1998 by and among the parties hereto, the Exhibits hereto and
the Disclosure Schedule constitute the entire agreement and understanding
between the parties relating to the subject matter hereof and thereof and
supersede all prior representations, endorsements, premises, agreements,
memoranda communications, negotiations, discussions, understandings and
arrangements, whether oral, written or inferred, between the parties relating to
the subject matter hereof. This Agreement may not be modified, amended,
rescinded, canceled, altered or supplemented, in whole or in part, except upon
the execution and delivery of a written instrument executed by a duly authorized
representative of each of the parties hereto.

         11.8 Governing Law. This Agreement shall be governed by and construed
and enforced in accordance with the laws of the State of Texas without giving
effect to choice of law principles.

         11.9 Waiver. The waiver of any breach of any term or condition of this
Agreement shall not be deemed to constitute the waiver of any other breach of
the same or any other term or condition.

         11.10 Severability. Any provision hereof that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         11.11 No Third Party Beneficiaries. Any agreement contained, expressed
or implied in this Agreement shall be only for the benefit of the parties hereto
and their respective legal representatives, successors and assigns, and such
agreements shall not inure to the benefit of the obligees of any indebtedness of
any party hereto, it being the intention of the parties hereto that no Person
shall be deemed a third party beneficiary of this Agreement, except to the
extent a third party is expressly given rights herein.

         11.12 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         11.13 Headings. Each statement set forth in the Disclosure Schedule
with respect to a particular section herein shall be deemed made solely with
respect to such section and not with respect to any other section hereof unless
specifically set forth in the Disclosure Schedule as also being made with
respect to such other section. The headings of the Articles and Sections of this
Agreement have been inserted for convenience of reference only and shall in no
way restrict or otherwise modify any of the terms or provisions hereof or affect
in any way the meaning or interpretation of this Agreement.

         11.14 Arbitration. In the event there shall exist any dispute or
controversy with respect to this Agreement or any matter relating hereto or the
transactions contemplated hereby, including, but not limited to Article 7, the
parties hereto agree to seek to resolve such dispute or controversy by mutual
agreement. If the parties hereto are unable to resolve such dispute or
controversy by agreement within 60 days following notice by any party hereto of
the nature of such dispute or controversy setting forth in reasonable detail the
circumstances and basis of such dispute or controversy, the parties agree that
such dispute or controversy be resolved by binding arbitration pursuant to the
provisions of this Section 11.14 and in accordance with the then current
Commercial Arbitration Rules of the American Arbitration Association. If a party
elects to submit such matter to arbitration, such party shall provide notice to
the other party of its election to do so, which notice shall name one
arbitrator. Within 10 days after the receipt of such notice, the other party
shall provide written notice to the electing party naming a second arbitrator.
The two arbitrators so appointed shall name a third arbitrator, or failing to do
so, a third arbitrator shall be appointed pursuant to the Commercial Arbitration
Rules of the American Arbitration Association. All arbitration proceedings shall
be held in Houston, Texas. Each arbitrator selected to act hereunder shall be
qualified by education and experience to pass on the particular question in
dispute and shall be independent and not affiliated with any of the parties
hereto. The arbitrators shall resolve all disputes in controversy in accordance
with the Texas substantive law. All statutes of limitations that would otherwise
be applicable shall apply to any arbitration proceeding. The arbitrators
appointed pursuant to this Section 11.14 shall promptly hear and determine
(after due notice and hearing and giving the parties reasonable opportunity to
be heard) the questions submitted, and shall render their decision within 60
days after appointment of the third arbitrator or as soon as practical
thereafter. If within such period a decision is not rendered by the board or a
majority thereof, new arbitrators may be named and shall act hereunder at the
election of either party in like manner as if none had previously been named.
The decision of the arbitrators, or a majority thereof, made in writing, shall
absent manifest error be final and binding upon the parties hereto as to the
questions submitted, and each party shall abide by such decision.

         11.15 Negotiated Transaction. The provisions of this Agreement were
negotiated by the parties hereto, and this Agreement shall be deemed to have
been drafted by all of the parties hereto.
