                           FORWARD-LOOKING STATEMENTS

     This prospectus and our other filings with the SEC 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
prospectus 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
prospectus. 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 1999, we have made the following assumptions:

     - The recent increase in the price of oil will not have an immediate
       favorable impact on our business.

     - Average natural gas prices for 1999 will remain at or near their current
       levels.

     - World demand for oil will be up only marginally or flat.

     - North American and international rig counts will remain at their current
       low levels.

     - 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.

     We have based these assumptions on various macro-economic 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 and international rig
counts are at historical or near historical lows, a continuation of the rig
count at its current level for a prolonged period of time would adversely affect
our results as demand for oil related products and services would continue to
fall because of the uncertainty relating to the future prices. In addition, any
further material declines in the current worldwide rig count or drilling
activity would likely further reduce the demand for our drilling products and
services. Our forward-looking statements regarding our drilling products assume
there will not be any further material declines in the worldwide rig count, in
particular the foreign 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, we may have to take additional
actions to achieve the desired savings.

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
                                        4
<PAGE>   6

leverage of our worldwide infrastructure and to enter new markets and expand in
existing markets with technologically advanced value-added products. Our
forward-looking statements have assumed only a small amount of near-term growth
from these new products and services.

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 strategy development, implementation and
testing phases of our Year 2000 program and expect it to be completed by the
fourth quarter of 1999.

ECONOMIC DOWNTURN IN ASIA AND SOUTH AMERICA COULD ADVERSELY AFFECT DEMAND FOR
PRODUCTS AND SERVICES.

     The economic downturn in Asia has begun to affect the economies in other
regions of the world, including South America and the Former Soviet Union. To
date, the economies in the United States and Europe have not been materially
affected. 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 fall further and adversely affect our revenues and income. We have assumed
that a worldwide recession will not occur as a result of the economic downturn
in Asia and South America. A material decline in the Chinese economy or
devaluation of its currency could cause further deterioration to the Asian and
world economies.

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.

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 SEC. For additional information regarding risks and
uncertainties, see our other current year filings with the SEC under the
Securities Exchange Act of 1934 and the Securities Act of 1933. We will
generally update our assumptions in our filings as circumstances require.

                                  RISK FACTORS

     An investment in our common stock involves various risks. When considering
your investment in our company you should consider carefully the following
factors, together with the information described elsewhere in this prospectus.

CONTINUED LOW PRICES FOR OIL WILL ADVERSELY AFFECT THE DEMAND FOR OUR PRODUCTS
AND SERVICES.

     Low oil prices adversely affect demand throughout the oil and natural gas
industry, including the demand for our products and services. As prices decline,
we are affected in two significant ways. First, the funds available to our
customers for the purchase of goods and services declines. Second, exploration
and drilling activity declines as marginally profitable projects become
uneconomic and either are delayed or eliminated. Accordingly, as long as oil
prices remain low, our revenues and income will be adversely affected. The
current market conditions have affected our business in various ways. Our
artificial lift business, which is heavily dependent on North American
production, experienced continuous declines in revenue throughout 1998 and the
first quarter of 1999. Our drilling products division has experienced a
significant decline in new orders of drill pipe and other drill stem products
and tubular sales have fallen as completion activity slowed and tubular
distributors reduced inventories. Sales in 1999 for our drill stem products
could be down by more than 50% from 1998. The level of decline will be dependent
on the timing of any increase of drilling activity and the amount of time it
takes for our customers' drill pipe and other tubular inventories to be reduced.
Our completion and oilfield services business has experienced declines in line
with the general reduction in industry activity, with the greatest declines
occurring in the United States markets. Our compression services business has
only been marginally affected by the recent declines in market conditions
because its business is based on levels of natural gas development and
production, which has been more stable than oil production.

     Our businesses will continue to be affected by industry conditions,
including those conditions and factors described under "Forward-Looking
Statements".

CUSTOMER CREDIT RISKS

     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 actual losses have historically been within our
expectations.

DISRUPTIONS IN FOREIGN OPERATIONS COULD ADVERSELY AFFECT OUR INCOME

     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, local economic
conditions, political disruption, civil disturbance and policies that may:

     - disrupt our operations and oil and gas exploration and production
       activities;

     - restrict the movement of funds;

     - lead to U.S. government or international sanctions; and

     - 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

                                        6
<PAGE>   8

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.

     Disruptions may occur in our foreign operations, and losses may occur that
will not be covered by insurance. Drill pipe and other products are manufactured
for us by Oil Country Tubular Limited in India under a long-term exclusive
manufacturing arrangement. Although we have sought to minimize the risks of this
operation through a manufacturing versus ownership arrangement, we are providing
OCTL with a substantial amount of raw materials, inventory and working capital
for the products it manufactures for us. Our Indian operations have been
adversely affected by the downturn of the economies in the eastern hemisphere.
Operations in India are subject to various political and economic risks as well
as financial risks with respect to OCTL. We have recently substantially
curtailed our operations in India and we expect these operations to continue to
be curtailed through the end of 1999. A termination or complete shutdown of this
operation in light of current market conditions or political factors could have
an adverse effect on our income and results.

OUR PRODUCTS AND SERVICES ARE SUBJECT TO OPERATIONAL, LITIGATION AND
ENVIRONMENTAL RISKS

     Our products are used for the exploration and production of oil and natural
gas. These operations are subject to hazards inherent in the oil and gas
industry that can cause personal injury or loss of life, damage to or
destruction of property, equipment, the environment and marine life, and
suspension of operations. These hazards include fires, explosions, craterings,
blowouts and oil spills. Litigation arising from an accident at a location where
our products or services are used or provided may result in our being named as a
defendant in lawsuits asserting potentially large claims.

     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.

     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.

CURRENCY DEVALUATION AND FLUCTUATION RISKS

     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.

     Over 50% of our net assets 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.

OUR COMMON STOCK HAS FLUCTUATED HISTORICALLY

     Historically, and in recent months in particular, the market price of
common stock of companies engaged in the oil and gas industry has been highly
volatile. Likewise, the market price of our common stock has varied
significantly in the past. News announcements and changes in oil and natural gas
prices, changes in the demand for oil and natural gas exploration and changes in
the supply and demand for oil and natural gas have all been factors that have
affected the price of our common stock.

                              SELLING STOCKHOLDERS

     This prospectus is part of a registration statement that we filed pursuant
to registration rights granted to the selling stockholders under an agreement we
entered into in connection with the acquisition by our Drilling Products
Division of certain of the assets of Texas Pup, Inc.

     Pursuant to the terms of the acquisition agreement, we will pay all
expenses of registering the shares under the Securities Act of 1933, including
all registration and filing fees, printing expenses and the fees and
disbursements of our counsel and accountants. The agreement also provides that
we will indemnify the selling stockholders against certain civil liabilities,
including liabilities under the Securities Act of 1933, or will contribute to
payments the selling stockholders may be required to make in respect thereof.
The selling stockholders will pay all fees and disbursements of their counsel
and all brokerage fees, commissions and expenses for any shares that they sell.
We expect to withdraw registration of any unsold shares on or shortly after July
7, 2000, when we expect the shares will be eligible for public sale pursuant to
the exemption from registration provided by Rule 144 under the Securities Act of
1933.

     The following table sets forth the beneficial ownership of common stock by
each selling stockholder as of July 26, 1999, all of which may be sold pursuant
to this prospectus:

(1) Because the selling stockholders may offer all or a portion of the shares
    pursuant to this prospectus, we cannot estimate to the number of shares of
    our common stock that the selling stockholders will hold upon termination of
    any sales.

(2) 10,500 of the shares beneficially owned by Texas Pup, Inc. are currently
    held in escrow.

     We currently employ Patrick E. Hosford, a shareholder, officer and director
of Texas Pup, Inc., at an annual base salary of $125,000. Within the past three
years, none of the selling stockholders has held any position, office or other
material relationship with us or any of our predecessors or affiliates, except
as noted above.

                              PLAN OF DISTRIBUTION

     The shares offered under this prospectus may be sold by the selling
stockholders from the date of this prospectus until July 7, 2000. The selling
stockholders may sell the shares on the New York Stock Exchange or otherwise, at
market prices or at negotiated prices. They may sell shares by one or a
combination of the following:

     - a block trade in which a broker or dealer will attempt to sell the shares
       as agent, but may position and resell a portion of the block as principal
       to facilitate the transaction;

     - purchases by a broker or dealer as principal and resale by the broker or
       dealer for its account pursuant to this prospectus;

     - ordinary brokerage transactions and transactions in which a broker
       solicits purchasers; and

     - privately negotiated transactions.

     Brokers or dealers engaged by the selling stockholders may arrange for
other brokers or dealers to participate in sales of shares. Brokers or dealers
will receive commissions or discounts from selling stockholders in amounts to be
negotiated prior to the sale. The selling stockholders and any broker-dealers
that participate in the distribution may be deemed to be "underwriters" within
the meaning of the Securities Act of 1933, and any proceeds or commissions
received by them or any profits on the resale of shares sold by broker-dealers,
may be deemed to be underwriting discounts and commissions.

     When any of the selling stockholders notifies us of a particular offering
of common stock under this prospectus, we will file a prospectus supplement, if
required by the Securities Act of 1933, setting forth:

     - the number of shares being offered and the terms of the offering,
       including the purchase price;

     - the name of each of the participating broker-dealers or agents;

     - the purchase price paid for the shares purchased from the selling
       stockholders; and

     - any items constituting compensation from the selling stockholders.

     We will not receive any of the proceeds from the sale of the shares offered
by this prospectus.

ITEM 15 INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Under Delaware law, a corporation may include provisions in its certificate
of incorporation that will relieve its directors of monetary liability for
breaches of their fiduciary duty to the corporation, except under certain
circumstances, including a breach of the director's duty of loyalty, acts or
omissions of the director not in good faith or which involve intentional
misconduct or a knowing violation of law, the approval of an improper payment of
a dividend or an improper purchase by the corporation of stock or any
transaction from which the director derived an improper personal benefit. The
Registrant's Amended and Restated Certificate of Incorporation, as amended,
provides that the Registrant's directors are not liable to the Registrant or its
stockholders for monetary damages for breach of their fiduciary duty, subject to
the described exceptions specified by Delaware law.

     Section 145 of the Delaware General Corporation Law grants to the
Registrant the power to indemnify each officer and director of the Registrant
against liabilities and expenses incurred by reason of the fact that he is or
was an officer or director of the Registrant if he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Registrant and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The Amended and Restated
By-laws of the Registrant provide for indemnification of each officer and
director of the Registrant to the fullest extent permitted by Delaware law.
David J. Butters and Robert B. Millard, employees of Lehman Brothers Inc.
("Lehman Brothers"), constitute two of the eight members of the Board of
Directors of the Registrant. Under the restated certificates of incorporation,
as amended to date, of Lehman Brothers and its parent, Lehman Brothers Holdings
Inc. ("Holdings"), both Delaware corporations, Messrs. Butters and Millard, in
their capacity as directors of the Registrant, are to be indemnified by Lehman
Brothers and Holdings to the fullest extent permitted by Delaware law. Messrs.
Butters and Millard are serving as directors of the Registrant at the request of
Lehman Brothers and Holdings.

     Section 145 of the Delaware General Corporation Law also empowers the
Registrant to purchase and maintain insurance on behalf of any person who is or
was an officer or director of the Registrant against liability asserted against
or incurred by him in any such capacity, whether or not the Registrant would
have the power to indemnify such officer or director against such liability
under the provisions of Section 145. The Registrant has purchased and maintains
a directors' and officers' liability policy for such purposes. Messrs. Butters
and Millard are insured against certain liabilities which they may incur in
their capacity as directors pursuant to insurance maintained by Holdings.

     As permitted by Item 601(b)(4)(iii)(A) of Regulation S-K, the Registrant
has not filed with this Registration Statement certain instruments defining the
rights of holders of long-term debt of the Registrant and its subsidiaries
because the total amount of securities authorized under any of such instruments
does not exceed 10% of the total assets of the Registrant and its subsidiaries
on a consolidated basis. The Registrant agrees to furnish a copy of any such
agreement to the Commission upon request.

ITEM 17. UNDERTAKINGS.

     The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this Registration Statement (or the most recent
        post-effective amendment hereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this Registration Statement
        or any material change to such information in this Registration
        Statement;

          Provided, however, that paragraphs (i) and (ii) do not apply if the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed with or furnished to the
     Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
     Exchange Act that are incorporated by reference in this Registration
     Statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered herein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the Securities Act or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. If a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

               (vi) all interests of the Seller as lessee in the real property
          described in Section 1.1(a)(vi) of the Disclosure Schedule (the
          "Leasehold Interests");

               (vii) all prepaid expenses and deposits made by the Seller; and

               (viii) any goodwill associated with the Seller.

          (b) The Seller shall use its best efforts to obtain such consents of
third parties as are necessary for the assignment of the Transferred Assets. To
the extent that any of the Transferred Assets are not assignable by the terms
thereof or consents to the assignment thereof cannot be obtained as provided
herein, the Transferred Assets shall be held by the Seller in trust for the
Buyer and shall be performed by the Buyer in the name of the Seller and all
benefits and obligations derived thereunder shall be for the account of the
Buyer; provided, however, that where entitlement of the Buyer to such
Transferred Assets hereunder is not recognized by any third party, the Seller
shall, at the request of the Buyer, enforce in a reasonable manner, at the cost
of and for the account of the Buyer, any and all rights of the Seller against
such third party.

          (c) Within three days of the Closing Date, the Seller shall notify
each Person which may have possession of any of the Transferred Assets at the
Closing Date, whether by consignment or otherwise, of the transfer of such
Transferred Assets to the Buyer.

     1.2 Excluded Assets. Anything in Section 1.1(a) to the contrary
notwithstanding, there shall be excluded from the assets, rights and business to
be transferred to the Buyer hereunder those assets of the Seller listed or
described in Section 1.2 of the Disclosure Schedule (collectively, the "Excluded
Assets").

     1.3 Closing. Subject to the conditions set forth in this Agreement, the
closing shall take place at the offices of the Buyer, 515 Post Oak Blvd., Suite
600, Houston, Texas, at 9:00 a.m. on July 7, 1999, or at such other time, date
or 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, control over
and risk of loss of the Transferred Assets shall pass to the Buyer at the
Closing.

     1.4 Purchase Price for the Assets. In consideration of the transfer to the
Buyer of the Transferred Assets, the Buyer shall, on the Closing Date, (a) cause
Weatherford to issue to the Seller the Weatherford Shares (the "Share Payment"),
(b) assume the obligations of the Seller to pay the Trade Payables of the
Seller's business incurred in the ordinary course of the Seller's business (the
"Assumed Trade Payables"), and (c) assume the obligations of the Seller under
the express written terms of the Entitlements to the extent and only to the
extent such obligations are not Pre-Closing Obligations (collectively, the
"Assumed Liabilities"), all of which Assumed Liabilities are listed in Section
1.4(c) of the Disclosure Schedule. The Share Payment, as adjusted by Section
1.5, the Assumed Trade Payables and the Assumed Liabilities are herein
collectively referred to as the "Purchase Price". Notwithstanding the foregoing,
an aggregate of 10% of the Weatherford Shares (the "Escrowed Shares") shall be
held in escrow by Weatherford pending the determination of the adjustment of the
Purchase Price, if any, in accordance with Section 1.5 hereof. No interest shall
be payable with respect to the Escrowed Shares.

     1.5 Purchase Price Adjustment.

          (a) The Buyer shall within 45 calendar days after the Closing Date,
prepare or cause to be prepared a balance sheet of the Seller of the Closing
Date (the "Statement") and shall deliver such Statement to the Representative.
The Buyer shall provide the Representative with access to copies of all work
papers and other relevant documents to verify the information contained in the
Statement. The Statement shall be prepared in accordance with GAAP. The
Representative shall have a period of 10



                                        2

<PAGE>   8



calendar days after delivery to him of the Statement to review it and make any
objections in writing to the Buyer. If written objections to the Statement are
delivered to the Buyer within such 10-day period, then the Buyer and the
Representative shall attempt to resolve the matter or matters in dispute. If no
written objections are made within the time period provided above, the Statement
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 Statement cannot be resolved by
the Buyer and the Representative within 15 calendar days after the delivery of
the objections to the Statement, 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 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
Representative its determination in writing on the specific matters in dispute,
including any resulting revisions to the Statement, which determination shall be
final and binding on the parties hereto. The Statement, 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 and the Seller equally.

          (c) At the time the Statement becomes final and binding on the parties
hereto:

               (i) The Buyer will pay the Seller an amount equal to (A) the
          amount, if any, by which the Closing Date Working Capital exceeds the
          Target Working Capital, less (B) the amount, if any, by which the
          Target Working Capital exceeds the Closing Date Working Capital, plus
          (C) the amount, if any, by which the Target Debt exceeds the Closing
          Date Debt, less (D) if the Closing Date Debt exceeds the Target Debt,
          an amount equal to (1) the amount, if any, by which the Closing Date
          Debt exceeds the Target Debt less (2) the amount, if any, by which the
          Closing Date Gross Book Value of the Equipment exceeds the Target
          Gross Book Value of the Equipment. Notwithstanding the foregoing, if
          the amount resulting from the calculation set forth in the immediately
          preceding sentence is equal to or less than zero, no payment shall be
          made by the Buyer to the Seller pursuant to this Section 1.5.

               (ii) The Seller will pay the Buyer an amount equal to (A) the
          amount, if any, by which the Target Working Capital exceeds the
          Closing Date Working Capital, less (B) the amount, if any, by which
          the Closing Date Working Capital exceeds the Target Working Capital,
          plus (C) if the Closing Date Debt exceeds the Target Debt, an amount
          equal to (1) the amount, if any, by which the Closing Date Debt
          exceeds the Target Debt less (2) the amount, if any, by which the
          Closing Date Gross Book Value of the Equipment exceeds the Target
          Gross Book Value of the Equipment, less (D) the amount, if any, by
          which the Target Debt exceeds the Closing Date Debt. Notwithstanding
          the foregoing, if the amount resulting from the calculation set forth
          in the immediately preceding sentence is equal to or less than zero,
          no payment shall be made by the Seller to the Buyer pursuant to this
          Section 1.5

          (d) Any payments made pursuant to this Section 1.5 shall be made in
shares of Common Stock within five days of the date that the Statement becomes
final and binding on the parties hereto. The number of shares of Common Stock to
be issued or transferred, as the case may be, shall be an amount equal to the
amount of the payment to be made by the Seller or the Buyer, as the case may be,
divided by the Average Closing Price. Any payments to be made by the Seller
pursuant to this Section 1.5 shall be made first from the Escrowed Shares and
then, as necessary, from the other Weatherford Shares issued to the Seller at
Closing. Within five Business Days of the date any such payment is made,
Weatherford shall deliver to the Seller the Escrowed Shares, if any, remaining
after any such payment. Any payments made pursuant to this Section 1.5 shall be
deemed to be adjustments to the Purchase Price.



                                        3

<PAGE>   9


          (e) For purposes of preparing the Statement, (i) there shall be no
increases in the carrying value of any assets of the Seller by virtue of any
adjustments made after December 31, 1998 and (ii) there shall be no increases in
the assets of the Seller due to the recognition of any non-cash increase after
December 31, 1998, other than in connection with sales and dispositions of
Inventory in the ordinary course of business.

     1.6 Liabilities Not Assumed by the Buyer. Except for the Assumed
Liabilities and the Assumed Trade Payables, the Seller shall pay and discharge
in due course all liabilities, debts and obligations relating to the Seller, the
Transferred Assets or the Seller's business, whether known or unknown, now
existing or hereafter arising, contingent or liquidated, including, without
limitation, (i) any Tax liabilities pertaining to any of the Seller or the
Transferred Assets for periods prior to and including the Closing Date, (ii) any
Debt Obligations (except for the Debt Obligations set forth in Section 1.6 of
the Disclosure Schedule, which Debt Obligations shall be repaid by Weatherford
on the Closing Date), (iii) all liabilities and obligations relating to any
products manufactured, sold or distributed or services provided by or on behalf
of the Seller or with respect to any claims made pursuant to warranties to third
Persons in connection with products manufactured, sold or distributed or
services provided by or on behalf of the Seller, (iv) all Pre-Closing
Obligations, (v) all liabilities and obligations of any Person arising prior to
the Closing or related to the conduct or operation of the Transferred Assets on
or prior to the Closing Date, and (vi) any Environmental Liability for which the
Buyer is entitled to be indemnified under Article 8 hereof (collectively, the
"Retained Liabilities"), and the Buyer shall not assume, or in any way be liable
or responsible for, any of such Retained Liabilities.

     1.7 Transfer Taxes; Recording Fees. The Buyer and the Seller acknowledge
and agree that the Purchase Price includes and is inclusive of any and all
sales, use, value added, stamp, transfer or other similar Taxes imposed as a
result of the consummation of the transactions contemplated by this Agreement,
and the Seller and the Shareholders hereby jointly and severally agree to
indemnify the Buyer against, and agree to protect, save and hold the Buyer
harmless from, any loss, liability, obligation or claim (whether or not
ultimately successful) for sales, use, transfer or other similar Taxes (and any
interest, penalties, additions to tax and fines thereon or related thereto)
imposed as a result of the consummation of the transactions contemplated by this
Agreement, including, without limitation, any liability to which any of the
parties may become subject as a result of the fact that the transactions
contemplated by this Agreement are effected without compliance with the bulk
sales provisions of the Uniform Commercial Code as in effect in any state or any
similar statute as enacted in any jurisdiction. The Buyer shall pay any and all
recording, filing or other fees relating to the conveyance or transfer of the
Transferred Assets from the Seller to the Buyer. The Buyer shall deliver to the
Seller on the Closing Date a certificate certifying that the Inventories are
being purchased for resale to the extent stated therein.

     1.8 Allocation of Purchase Price. The Purchase Price shall be allocated
among the Transferred Assets by the Buyer in its sole discretion.

     1.9 Prorations of Certain Taxes. The Seller and the Shareholders warrant
that the Transferred Assets are not, and on the Closing Date will not be,
subject to or liable for any special assessments or similar types of
impositions. Any general property Tax assessed against or pertaining to the
Transferred Assets for the taxable period that includes the Closing Date shall
be prorated between the Buyer and the Seller as of the Closing Date. In the
event the amount of any such general property Tax cannot be ascertained as of
the Closing Date, proration shall be made on the basis of the preceding year,
the Buyer shall receive a credit against the Share Payment on the Closing Date
for the Seller's pro rata portion of such general property Taxes, and to the
extent that such proration may be inaccurate, the Seller and the Buyer agree to
make such payment to the other after the tax statements have been received as is
necessary to allocate such general property Tax properly between the Seller and
the Buyer as of the Closing Date.

binding effect or enforceability thereof.

          (b) All licenses, permits, concessions, warrants, franchises and other
governmental authorizations and approvals of all Governmental Entities required
or necessary for the Seller to carry on its business in the places and in 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.

The Seller and each of the Shareholders understand and agree 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
Seller. Weatherford agrees that any Weatherford Shares sold pursuant to an
effective registration statement, including a registration statement filed
pursuant to Article 4 hereof, 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 Seller 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.

          (a) Weatherford will use its best efforts to register under the
Securities Act the Weatherford Shares pursuant to a non-underwritten offering
having a period of distribution not to exceed one year from the Closing Date. In
furtherance of such obligation, Weatherford shall file, within 30 Business Days

4.1, Weatherford shall not be obligated to prepare and file the Registration
Statement pursuant to this Section 4.1, or prepare or file any amendment or
supplement thereto, at any time when Weatherford reasonably believes that the
filing thereof, or the offering of securities pursuant thereto, would adversely
affect a pending or proposed public offering of securities of Weatherford, an
acquisition, merger, recapitalization, consolidation, reorganization or similar
transaction relating to Weatherford or negotiations, discussions or pending
proposals with respect thereto or require premature disclosure of information
not otherwise required to be disclosed to the potential detriment of
Weatherford.

          (c) Notwithstanding anything to the contrary contained in this Section
4.1, Weatherford shall be permitted, on written notice to the Seller Group, to
suspend the period of sale or distribution of the Weatherford Shares at any time
when Weatherford reasonably believes that the sale or distribution thereof would
adversely affect a pending or proposed public offering of securities of
Weatherford, an acquisition, merger, recapitalization, consolidation,
reorganization or similar transaction relating to Weatherford or negotiations,
discussions or pending proposals with respect thereto or require premature
disclosure of information not otherwise required to be disclosed to the
potential detriment of Weatherford.

supplement thereto, by Weatherford may not be deferred pursuant to Section
4.1(b), and the sale and distribution of the Weatherford Shares may not be

in the case of a public offering) of any of the proposals or transactions
described therein or, in any event, for more than 120 days.

          (e) The Seller Group agrees and covenants to fully cooperate with and
assist Weatherford and its counsel and representatives in connection with
Weatherford's obligations under this Article 4, including providing such
information as requested by Weatherford in connection the preparation of the
Registration Statement and the resale of the Weatherford Shares.

shorter period of time until the transfer or sale of all the Weatherford Shares
has been completed;

          (b) as expeditiously as reasonably practicable, prepare and file with
the Commission such amendments and supplements to the Registration Statement and
the prospectus used in connection



                                       13

<PAGE>   19



therewith as may be necessary to keep the Registration Statement effective and
to comply with the provisions of the Securities Act with respect to the
disposition of the Weatherford Shares covered by the Registration Statement in
accordance with the intended method of distribution set forth therein;

          (c) as expeditiously as reasonably practicable, furnish to the Seller
Group such number of copies of prospectuses and preliminary prospectuses in
conformity with the requirements of the Securities Act, and such other documents
as the Seller Group may reasonably request, in order to facilitate the public
sale or other disposition of the Weatherford Shares owned by the Seller Group;
provided, however, that the obligation of Weatherford to deliver copies of
prospectuses or preliminary prospectuses to the Seller Group shall be subject to
the receipt by Weatherford of reasonable assurances from the Seller Group that

other securities laws as may be applicable in connection with any use by it of
any prospectuses or preliminary prospectuses;

          (d) as expeditiously as practicable, use its best efforts to register
or qualify the Weatherford Shares under such other securities laws of such
United States jurisdictions as the Seller Group shall reasonably request
(considering the nature and size of the offering) and do any and all other acts

consummate the public sale or other disposition in such jurisdictions of the
Weatherford Shares; provided, however, that Weatherford shall not be required to
qualify to transact business as a foreign corporation in any jurisdiction in

action which would subject it to general service of process in any jurisdiction
in which it is not then so subject; and

          (e) bear all Registration Expenses (as defined below) in connection
with the registration hereunder; provided, however, that all Selling Expenses

connection with any such registration or resale are herein referred to as
"Selling Expenses".

Securities Act pursuant to this Agreement, Weatherford will indemnify and hold
harmless the Seller Group and any other Person, if any, who controls the Seller
Group within the meaning of Section 15 of the Securities Act, against any
losses, claims, damages or liabilities, joint or several, to which the Seller
Group or such controlling Person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities or actions in
respect thereof arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained, on the effective date thereof,
in the Registration Statement, any preliminary prospectus distributed with the
consent of Weatherford or final prospectus contained therein, or any amendment
thereof or supplement thereto, including all documents incorporated by reference
therein, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will, unless Weatherford assumes the
defense as provided in Section 4.3(c), promptly following request and receipt of
reasonable supporting documents, such as invoices, reimburse the Seller Group
and each such controlling Person for any legal or any other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that Weatherford will not
be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in such Registration Statement,
such preliminary prospectus, such final prospectus or such amendment or
supplement, including



                                       14

<PAGE>   20


all documents incorporated by reference therein, in reliance upon and in
conformity with written information furnished to Weatherford by or on behalf of
the Seller Group or a controlling Person thereof specifically for use in the
preparation thereof.

          (b) In the event of any registration of the Weatherford Shares under
the Securities Act pursuant to this Agreement, the Seller Group will jointly and
severally indemnify and hold harmless Weatherford and the Buyer and each Person,
if any, who controls Weatherford or the Buyer within the meaning of Section 15
of the Securities Act, each officer of Weatherford who signs the Registration
Statement, each director of Weatherford and each Person who controls any
underwriter (if any) within the meaning of Section 15 of the Securities Act,
against any and all such losses, claims, damages, liabilities or actions which
Weatherford or such officer, director, underwriter (if any) or controlling
Person may become subject under the Securities Act or otherwise, and will
reimburse Weatherford, each such officer, director, underwriter (if any) and
controlling Person for any legal or any other expenses reasonably incurred by
such party in connection with investigating or defending any such loss, claim,
damage, liability or action, if (i) such loss, claim, damage, liability or
action in respect thereof arises out of or is based upon any untrue statement or
alleged untrue statement of any material fact contained in the Registration
Statement or any such prospectus, or any amendment thereof or supplement
thereto, or arises out of or is based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading and such statement or omission of a
material fact was made in reliance upon and in conformity with written
information furnished to Weatherford by or on behalf of the Seller Group
specifically for use in connection with the preparation of the Registration
Statement or prospectus or (ii) such loss, claim, damage, liability or action in
respect thereof arises out of or is based upon the Seller Group's failure to
deliver any required prospectus or otherwise comply with applicable laws
regarding the same.

          (c) Promptly after receipt by any indemnified Person of notice of any
claim or commencement of any action in respect of which indemnity is to be
sought against an indemnifying Person pursuant to this Agreement, such
indemnified Person shall notify the indemnifying Person in writing of such claim
or of the commencement of such action, and, subject to provisions hereinafter
stated, in case any such action shall be brought against an indemnified Person
and such indemnifying Person shall have been notified of the same, such
indemnifying Person shall be entitled to participate therein, and, to the extent
it shall wish, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified Person, and after notice from the indemnifying
Person to such indemnified Person of its election to assume the defense thereof,
such indemnifying Person shall not be liable to such indemnified Person in
connection with the defense thereof; provided, however, if there exists or will
exist a conflict of interest which would make it inappropriate in the reasonable
judgment of the indemnified Person for the same counsel to represent both the
indemnified Person and such indemnifying Person then such indemnifying Person
shall be entitled to retain its own counsel at the expense of such indemnifying
Person; provided further, however, the indemnifying Person shall not be required
to pay for more than one separate counsel for all of the indemnified Persons in
addition to any local counsel. Payment of any amounts due pursuant to this
Section 4.3 shall be made within ten Business Days after notice is sent by the
indemnified Person.

     4.4 Termination. If Rule 144 or Rule 145 as promulgated under the
Securities Act or any successor or similar rule or statute shall permit the sale
of the Weatherford Shares, the rights of the Seller Group as to the registration
provided for in this Agreement as to the Weatherford Shares shall terminate
immediately.

     the Transferred Assets that would reasonably be expected to have a material
     or adverse effect on the Seller or the Transferred Assets whether or not
     occurring in the ordinary course of business.

     5.3 Negotiation with Others. The Seller agrees that from the date hereof
until the Closing Date or the termination of this Agreement pursuant to Section
10.1, the Seller will not, directly or indirectly, solicit, encourage or
negotiate with any Person not a party hereto or not affiliated with a party
hereto with respect to a merger, consolidation, asset or stock purchase or any
similar transaction with the Seller.

     5.4 Information. During the period from the date of this Agreement to the
Closing Date, the Buyer and the Seller will promptly inform the other in writing
of any claim, action or any proceeding commenced against such party with respect
to the transactions contemplated by this Agreement or any assets or property of
the Seller or the Transferred Assets.

     5.5 Delivery of Business Documents. At Closing, the Seller shall deliver to
the Buyer all Documents and Other Papers relating to the Transferred Assets, the
Assumed Liabilities and the Seller's current and proposed operations, including,
without limitation, all files relating to the Accounts Receivable, the Assumed
Trade Payables, copies of all insurance policies and all files relating thereto,
computer disks reflecting any books or records, documents or other papers, or
other information or data relating to the operation of the Seller's business,
the Transferred Assets or the Assumed Liabilities stored on any electronic
media, including computers. The Seller, however, shall be entitled to retain the
corporate minute books of



                                       17

<PAGE>   23



the Seller and to have access to the books and records relating to the Seller to
the extent such books and records are necessary for the preparation of tax
returns.

     5.6 Further Assurances. The Seller 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
reasonably 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 Transferred Assets
free and clear of all Liens (including the release of all Liens of record) and
shall use 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.

     5.7 Nondisclosure of Proprietary Information.

          (a) The Seller and each of the Shareholders agree that, from and after
the Closing, such Person and such Person'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
three years solicit or hire any employees of the Seller who are subsequently
employed by the Buyer or offered employment by the Buyer.

          (b) The Seller and each of the Shareholders acknowledge that all
Documents and Other Papers and objects containing or reflecting any Proprietary
Information, whether developed by the Seller or any of the Shareholders or by
someone else for such Person or any of such Person's 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
Seller and each of the Shareholders understand and agree that the breach or
anticipated breach of the obligations under this Section 5.7 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.

     5.8 Covenant Not to Compete With the Business. The Seller and each of the
Shareholders agree that, effective as of the Closing Date and for a period of
five years thereafter, none of the Seller, the Shareholders, nor any of their
respective Affiliates shall, without the consent of the Buyer, directly or
indirectly, design, develop, market, produce, manufacture, rent, sell or provide
trenchless drill pipe or oilfield tubular accessories or provide related
products or services in any geographical area of the world, or, except for the
benefit of Buyer and its Affiliates, assist any Person to do the same. The
Seller and each of the Shareholders acknowledge that a remedy at law for any
breach or attempted breach of this Section 5.8 will be inadequate and further
agree that any breach of this Section 5.8 will result in irreparable harm to the
Buyer and 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 and shall be entitled to
terminate the Seller Group's registration rights under Article 4. The Seller and
each of the Shareholders acknowledge that this covenant not to compete is being
provided as an inducement to the Buyer to acquire the Transferred Assets and
that this Section 5.8 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 5.8 shall be
interpreted in such a manner as to be effective and valid under applicable law
but if any provision of this Section 5.8 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 5.8. If any provision of this Section 5.8 shall, for any reason, be
judged by any



                                       18

<PAGE>   24



court of competent jurisdiction to be invalid or unenforceable, such judgment
shall not affect, impair or invalidate the remainder of this Section 5.8 but
shall be confined in its operation to the provision of this Section 5.8 directly
involved in the controversy in which such judgment shall have been rendered. In
the event that the provisions of this Section 5.8 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.

     5.9 Use of Names. All uses of the name "Texas Pup, Inc." or any derivations
thereof (collectively, the "Names") are being transferred to the Buyer hereunder
as part of the Transferred Assets. The Seller agrees that it will not take any
action which could reasonably be expected to adversely affect the Buyer's right
to the Names or cause confusion with respect to the Buyer's use of the Names.
All goodwill with respect to the use of the Names will inure to the benefit of
the Buyer, and the Seller will not have any rights to sue or recover against any
person with respect to the use of the Names. Within ten days after Closing, the
Seller agrees to take all necessary action to change the Seller's name to one
bearing no resemblance to any of the Names or any derivation thereof and will
forever cease the use of such names.

     5.10 Employee Matters

          (a) The Buyer shall offer employment to all of the employees of the
Seller except the Seller's plant manager ("the Personnel") as of the Closing. In
that regard, the Buyer shall have the right to interview the Personnel at any
time after the date hereof. The Buyer shall not assume any liabilities or
obligations of the Seller with respect to the Personnel, including those persons
hired by the Buyer. In determining eligibility for and entitlement to vacation
and other normal benefits (excluding stock-based plans and incentive programs)
based on length of service by those persons hired by the Buyer under the Buyer's
normal policies, service with the Seller shall be considered by the Buyer and
its Affiliates as service with the Buyer and its Affiliates.

          (b) The Buyer shall have no obligation to provide severance benefits
on behalf of any employees of the Seller. The Seller acknowledges that it is
solely responsible for issuing, serving and delivering all notices required, if
any, pursuant to the WARN Act in connection with the terminations of employment
of employees of the Seller and for any financial obligations and liabilities in
connection therewith or otherwise required in connection with the terminations
of employment of employees of the Seller.

          (c) The Seller shall be solely responsible for providing notices and
group health plan continuation coverages in compliance with COBRA with respect
to qualifying events occurring on or before the Closing Date that relate to
current or former employees of the Seller and their associated qualified
beneficiaries.

          (d) The parties hereto do not intend to create any third-party
beneficiary rights respecting any employee of the Seller as a result of the
provisions hereof and specifically hereby negate any such intention.

     5.11 Payment of Obligations. Except as set forth in Section 5.11 of the
Disclosure Schedule, immediately prior to the Closing, the Seller shall pay to
the Shareholders all indebtedness and other obligations that it owes to the
Shareholders or their respective Affiliates as of the Closing and the
Shareholders and their respective Affiliates shall pay to the Seller all
indebtedness and other obligations owed to the Seller.

     5.12 Stock Exchange Listing Approval. Weatherford will use its best efforts
to obtain the approval of the New York Stock Exchange to the listing of the

                                    ARTICLE 8

                                 INDEMNIFICATION

     8.1 Indemnification by the Seller and the Shareholders. Except as otherwise
limited by this Article 8 and Article 9 hereof, the Seller and the Shareholders
jointly and severally 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 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 warranty or breach of any
covenant or agreement made or undertaken by the Seller or the Shareholders in
this Agreement or any misrepresentation in or omission from any other agreement,
certificate, exhibit or writing delivered to the Buyer or Weatherford pursuant
to this Agreement, including the Disclosure Schedule;

          (b) any Environmental Liability arising from or attributable to (i)
any condition, event, circumstance, activity, practice, incident, action or
omission existing or occurring prior to the Closing Date and related in any way
to the Transferred Assets or the Seller, (ii) any Environmental Conditions
existing on, at, or underlying the real property of the Seller located at 640
State Highway 75 North in Willis, Texas (the "Willis Facility"), (iii) any acts
or omission of the Seller relating to the ownership or operation of the
Transferred Assets or the Willis Facility on or prior to the Closing Date
resulting in a violation or alleged violation of Environmental Laws, or (iv) the
use, storage, disposal or treatment, or the transportation for storage, disposal
or treatment, of Hazardous Materials prior to the Closing Date and related in

liability under Section 8.1(b) for any Environmental Liability arising from or
attributable to the Phase II activities of Roy F. Weston, Inc. at the Willis
Facility on May 25, 1999 and May 26, 1999. Except as set forth in Section 8.8,
this indemnification provision shall survive the Closing without limitation.


                                       22

<PAGE>   28

     8.2 Indemnification by the Buyer and Weatherford. Except as otherwise
limited by this Article 8 and Article 9 hereof, the Buyer and Weatherford
jointly and severally agree to indemnify, defend and hold the Seller, the
Shareholders and each of their respective officers, directors, employees,
agents, shareholders and controlling Persons and successors and assigns harmless
from and against and in respect of Damages actually suffered, incurred or
realized by such party (collectively, "Seller 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 Seller or the Shareholders
pursuant to this Agreement; or (b) any property damage or personal injury or
death that may occur as a result of the move by the Buyer of the Transfer Assets
from the Willis Facility, to the extent caused by the negligence or other fault
of the Buyer or its employees, agents or representatives.

     8.3 Procedure. All claims for indemnification under this Article 8 shall be
asserted and resolved as follows:

          (a) An Indemnitee shall promptly give the Indemnitor notice of any
matter which an Indemnitee has determined has given or could give rise to a
right of indemnification under this Agreement, stating the amount of the Losses,
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 8 with respect to Losses arising from claims of any third party that are
subject to the indemnification provided for in this Article 8 ("Third Party
Claims") shall be governed by and contingent upon the following additional terms
and 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 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 or the Indemnitor.

     8.4 Payment. Payment of any amounts due pursuant to this Article 8 shall be
made in United States dollars in immediately available funds by wire transfer to
a bank account or accounts to be designated by the Indemnitee within ten
Business Days after notice is sent by the Indemnitee.

     8.5 Failure to Pay Indemnification. If and to the extent the Indemnitee
shall make written demand upon the Indemnitor for indemnification pursuant to
this Article 8 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


                                       23

<PAGE>   29


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.

     8.6 Adjustment of Liability. The amount which an Indemnitee shall be
entitled to receive from an Indemnitor with respect to any indemnifiable Losses
under this Article 8 shall be net of any insurance recovery by the Indemnitee on
account of such Losses from an unaffiliated party.

     8.7 Express Negligence. THE INDEMNITIES SET FORTH IN THIS ARTICLE 8 ARE
INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS
TERMS AND SCOPE THEREOF NOTWITHSTANDING TEXAS' EXPRESS NEGLIGENCE RULE 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.

     8.8 Indemnification Limitations. The Shareholders shall be liable under
Section 8.1(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 $25,000; provided, however, the Shareholders' liability under
Section 8.1(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, 2.4, 2.9, 2.12 or
2.14. There shall be no limits on the Shareholders' liability (i) under Section
8.1(a) only with respect to breaches of covenants or agreements (except as set
forth in the immediately preceding sentence) or (ii) under Sections 8.1(b) or
8.1(c).


                                    ARTICLE 9

                 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
for a period of two years from the Closing Date (except that the representations
and warranties set forth in Sections 2.1, 2.2, 2.4, 2.9, 2.12 and 2.14 shall
survive the Closing Date without limitation) (the period during which the
representations and warranties shall survive being referred to herein with
respect to such representations and warranties as the "Survival Period"), and
shall be effective with respect to any inaccuracy therein or breach thereof (and
a claim for indemnification under Article 8 hereof may be made thereon) if a
written notice asserting the claim shall have been given within the Survival
Period with respect to such matter. Any claim for indemnification made during
the Survival Period shall be valid and the representations and warranties
relating thereto shall remain in effect for purposes of such indemnification
notwithstanding such claim may not be resolved within the Survival Period. The
agreements and covenants set forth herein shall survive without limitation. All
representations, warranties, covenants and agreements made by the parties shall
not be affected by any investigation heretofore or hereafter made by and on
behalf of either of them and shall not be deemed merged into any instruments or

                  [Weatherford International, Inc. Letterhead]

July 26, 1999


Weatherford International, Inc.
515 Post Oak Boulevard, Suite 600
Houston, Texas  77027

Ladies and Gentlemen:

         I am Senior Vice President, General Counsel and Secretary of
Weatherford International, Inc., a Delaware corporation (the "Company"), and
have acted as counsel for the Company in connection with the registration under
the Securities Act of 1933 of 105,000 shares of the Company's common stock,
$1.00 par value (the "Shares"), to be offered by certain selling stockholders of
the Company (the "Selling Stockholders") upon the terms and subject to the
conditions set forth in the Company's Registration Statement on Form S-3
covering the Shares (the "Registration Statement") filed with the Securities and
Exchange Commission.

         In connection therewith, I have examined the Registration Statement,
originals or copies certified or otherwise identified to my satisfaction of the
Amended and Restated Certificate of Incorporation, as amended, of the Company,
the amended By-laws of the Company, the corporate proceedings with respect to
the offering of the Shares and such other documents and instruments as I have
deemed necessary or appropriate for the expression of the opinions contained
herein.

         I have assumed the authenticity and completeness of all records,
certificates and other instruments submitted to me as originals, the conformity
to original documents of all records, certificates and other instruments
submitted to me as copies, the authenticity and completeness of the originals of
those records, certificates and other instruments submitted to me as copies and
the correctness of all statements of fact contained in all records, certificates
and other instruments that I have examined.

         Based on the foregoing, and having regard for such legal considerations
as I have deemed relevant, I am of the opinion that the Shares proposed to be
offered by the Selling Stockholders have been duly and validly authorized for
issuance and are duly and validly issued, fully paid and nonassessable.

         The opinions expressed herein relate solely to, are based solely upon
and are limited exclusively to the General Corporation Law of the State of
Delaware and the federal laws of the United States of America, to the extent
applicable, and I am expressing no opinion as to the effect of the laws of any
other jurisdiction.

         I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of my name under the caption "Legal
Matters" in the Prospectus included as part of the Registration Statement.


                                                     Very truly yours,

                                                     /s/ Curtis W. Huff

                                                     Curtis W. Huff
