                           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 and in our other filings with the SEC and public releases. Our
results for 1999 were materially and adversely affected by the downtown in the
industry that began in 1998. Although we currently expect that our results for
2000 will show a material improvement over 1999 due to higher oil prices and
drilling activity and a general industry view that market conditions have
bottomed out and are beginning to recover, the oil and gas industry is extremely
volatile and subject to change based on political and economic factors outside
our control.

     Our estimates as to future results and industry trends make assumptions
regarding the future prices of oil and gas, the North American and international
rig counts and their effect on the demand and pricing of our products and
services. In analyzing the market and its impact on us for 2000, we have made
the following assumptions:

     - The recent increase in the price of oil will result in improvements to
       our business in 2000 with the strongest improvements expected to occur in
       the second half of 2000.

     - Oil prices will average over $20 per barrel for West Texas intermediate
       crude.

     - Average natural gas prices for 2000 will remain at or near their current
       levels.

     - World demand for oil will be up only slightly.

     - 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.

     - 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 have made our internal budgets
       based upon an average rig count for North America of around 1,100 and the
       international rig count of around 630.

     - Pricing for many of our products and services should increase steadily
       during the year. Pricing will be subject to market conditions and
       continued pricing pressures in selected markets and product lines.

     - Demand for compression services will remain relatively flat for most of
       2000.

     - 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 FUTURE REDUCTION IN THE 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. Although the North American rig count has improved
slightly from its historical low in 1999, a further

                                        3
<PAGE>   6

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 material declines in the worldwide rig count, in particular the domestic
rig count. Our forward-looking statements also assume an increase in the
international markets to occur by mid 2000.

PROJECTED COST SAVINGS COULD BE INSUFFICIENT.

     During 1998 and 1999, 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.

GRANT SPIN-OFF.

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

INTEGRATION OF ACQUISITIONS.

     During 1999, we 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. 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 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.

     To date, we do not know of any failures of our software, hardware,
equipment or products or those of our suppliers, vendors or customers as a
result of the occurrence of the Year 2000 date change; however, any such failure
could have a material impact on us. We have assumed that no material Year 2000
failures will occur.

AN 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 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

                                        4
<PAGE>   7

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 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.

LOW PRICES FOR OIL 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 are low, our revenues and income will be adversely affected. Despite the
increases in the price of oil during 1999, the market conditions existing in
1998 and 1999 affected our business in various ways. Our drilling and
intervention services business experienced declines in line with the general
reduction in industry activity. Our completion systems business experienced
declines corresponding to the lower activity levels, with the greatest declines
outside the United States markets. 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 Grant Prideco
drilling products division, which is classified as a discontinued operation,
experienced a significant decline in new orders of drill pipe and other drill
stem products and tubular sales fell as completion activity slowed, tubular
distributors reduced inventories and due to excess drill pipe being consumed
from idle rigs. Our compression services business has only been marginally
affected by the 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 compression business was subject to price competition
in North America.

     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 slowed the
payment of their accounts in 1999 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 CIS, Algeria, Nigeria,
parts of the Middle East, the Asia-Pacific region and Latin America, have been

                                        6
<PAGE>   9

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.

     Grant Prideco recently decided to terminate an existing arrangement in
India with Oil Country Tubular Limited, which resulted in a one time charge of
$6.1 million, net of tax, directly related to the write off of certain assets in
India. OCTL manufactured drill pipe and other products for us under a long-term
exclusive manufacturing arrangement. Over the years, Grant Prideco provided OCTL
with a substantial amount of raw materials, inventory and working capital for
the products it manufactures for us. Grant Prideco's business in India through
OCTL has been adversely affected by the downturn of the economies in the eastern
hemisphere and is subject to various political and economic risks as well as
financial and operational risks with respect to OCTL.

     As of December 31, 1999, OCTL owed Grant Prideco approximately $25.1
million for prior advances made by it to OCTL and Grant Prideco had assets in
India with a book value of approximately $1.7 million. In 1999, Grant Prideco
substantially curtailed its purchases from OCTL, and decided to terminate its
existing manufacturing relationship with OCTL and seek an alternative
arrangement for the recovery of its prior advances. After giving effect to the
$6.1 million after tax writeoff noted above, Grant Prideco's remaining exposure
in India is approximately $17.3 million and consists of unpaid receivable and
advances made to assist OCTL in its working capital needs as part of Grant
Prideco's manufacturing arrangement with it. Grant Prideco is currently
discussing with OCTL a restructuring of its relationship that would allow OCTL
to repay prior advances in cash, equity in OCTL or product. Based on financial
information of OCTL known to Grant Prideco and its general knowledge of the
business and assets of OCTL, OCTL would appear to have a sufficient asset and
equity value to allow for a restructuring of its debt to Grant Prideco on the
terms being discussed. There is, however, uncertainty as to how much, if any, of
the amounts owed to Grant Prideco by OCTL will ultimately be collected.
Accordingly, there can be no assurance that Grant Prideco will be able to fully
realize the amounts owed to it by OCTL or that additional charges relating to
India will not be required in the near term as the negotiation and collection
process continues. Any additional charges prior to spin-off would adversely
affect Grant Prideco's results and reduce our net income.

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

                                        7
<PAGE>   10

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 business operations; however, we do not
foresee that the transition to the Euro will have a significant impact.

     Approximately 45% to 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 section 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.

WE ARE SUBJECT TO RISKS RELATED TO THE YEAR 2000 THAT COULD NEGATIVELY IMPACT
OUR BUSINESS

     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, 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. All phases of
our Year 2000 plan have been completed. To date, we do not know of any failures
of our software, hardware, equipment or products or those of our suppliers,
vendors or customers as a result of the occurrence of the Year 2000 date change;
however, any such failure could have a material impact on us. Because no
material adverse effects from the Year 2000 have occurred, we are unable to
predict the most likely worst case Year 2000 scenario.

                              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 Completion Systems
Division of the minority stockholders' and phantom stockholder's interest in
SubTech International, Inc. Prior to the acquisition, we owned 51% of the stock
of SubTech. SubTech was formed in October 1998 for purposes of forming a joint
venture among us, the selling stockholders and certain other parties.

     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 are
registered and that they sell. We expect to withdraw registration of any unsold
shares on or shortly after February 3, 2001, 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 March 6, 2000, all of which may be sold pursuant

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:

       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

     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.

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

                                      II-4

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.

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, hereunto duly
authorized, in the City of Houston, State of Texas, on March 6, 2000.

                  (b) Such Stockholder or Phantom Stockholder represents and
warrants that (i) such Stockholder or Phantom Stockholder either is an
"accredited investor" within the meaning of Regulation D promulgated by the
Commission pursuant to the Securities Act and is not relying on a financial
advisor in connection with his or its participation in the transactions
contemplated hereby, or is not an accredited investor and the Stockholders
Representative is such Stockholder's or Phantom Stockholder's "purchaser

pursuant to the Securities Act in connection with evaluating the merits and
risks of this Agreement, the transactions contemplated hereby and an investment
in the Securities and the suitability thereof as an investment therefor, (ii)
such Stockholder or Phantom Stockholder, individually or together with the
Stockholders Representative, has such knowledge and experience in financial,
investment and business matters, such experience being based on actual
participation therein, that such Stockholder or Phantom Stockholder,
individually or together with the Stockholders Representative, is capable of
evaluating the merits and risks of this Agreement, the transactions contemplated
hereby and an investment in the Securities and the suitability thereof as an
investment therefor, (iii) the Securities will be acquired for such
Stockholder's or Phantom Stockholder's own account solely for investment and not
with a view toward resale or redistribution in violation of the Securities Laws,
(iv) such Stockholder or Phantom Stockholder, individually or together with the
Stockholders Representative, has reviewed such Stockholder's or Phantom
Stockholder's financial condition and commitments, and such Stockholder or
Phantom Stockholder, individually or together with the Stockholders
Representative, is satisfied that such Stockholder or Phantom Stockholder has
adequate means and providing for such Stockholder's or Phantom Stockholder's
financial needs and possible contingencies, has no present or existing or
contemplated future need to dispose of all or any portion of such Stockholder's
or Phantom Stockholder's interest in the Securities to satisfy any existing or
contemplated undertaking, need or indebtedness, and has assets or sources of
income that, taken together, are more than sufficient so that such Stockholder
or Phantom Stockholder can bear the risk of the loss of his or its entire
investment in the Securities, (v) such Stockholder or Phantom Stockholder has no
plan or intention to sell, exchange or otherwise dispose of his or its interest
in the Securities, (vi) such Stockholder or Phantom Stockholder is a natural
person whose residence and domicile are set forth on Annex A hereto or an entity
as described on Annex A hereto and (vii) in connection with the transactions

of WEI or as to the value of the Securities. Such Stockholder or Phantom
Stockholder understands that such Stockholder or Phantom Stockholder must bear
the economic risks of such Stockholder's or Phantom Stockholder's investment in
the Securities for an indefinite period of time. If such Stockholder or Phantom
Stockholder is relying upon the Stockholders Representative in such connection,
the Stockholders Representative has disclosed to such Stockholder or Phantom
Stockholder any material relationship between himself and his Affiliates and
SubTech, WEI or any of their respective Affiliates during the past two years or
currently contemplated and any compensation received or to be received as a
result of such relationship. Such Stockholder or Phantom Stockholder understands
that WEI is not under any obligation to file a registration statement or to take
any other action under the Securities Laws with respect to any Securities except
as expressly set forth in Article 12 hereof.

                  (c) Such Stockholder or Phantom Stockholder has consulted with
such Stockholder's or Phantom Stockholder's own counsel in regard to the

counsel other than Chamberlain, Hrdlicka, White, Williams and Martin and is
fully aware (i) of the circumstances under which such Stockholder or

                                      -10-

<PAGE>   15



Phantom Stockholder 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. Such Stockholder or Phantom
Stockholder has been advised by such Stockholder's or Phantom Stockholder's
counsel as to the provisions of Rules 144 and 145 as promulgated by the
Commission under the Securities Act and has been advised of the applicable
limitations thereof. Such Stockholder or Phantom Stockholder acknowledges that

investor" but has not been provided to the other Stockholders or Phantom
Stockholders. Such Stockholders' or Phantom Stockholders' legal counsel has
provided such Stockholder and Phantom Stockholder and the Stockholders
Representative with the SEC Documents and such summary descriptions. Such
Stockholder and Phantom Stockholder and the Stockholders Representative have
reviewed copies of the SEC Documents and such summary descriptions and have
attended one or more meetings at which representatives of WEI and counsel to WEI
and to such Stockholder or Phantom Stockholder have made presentations
concerning this Agreement and the transactions contemplated hereby (all such
written materials, including this Agreement and the Exhibits, Annexes and
Schedules hereto, and such presentations are hereinafter referred to as the
"Disclosure Information") and no person has made any representations or
warranties of any kind or nature to induce such Stockholder or Phantom
Stockholder to enter into this Agreement except as set forth in the written
Disclosure Information. WEI has made available to such Stockholder or Phantom
Stockholder and the Stockholders Representative the opportunity to ask questions
of, and receive answers from, its representatives concerning the terms and
conditions of the transactions contemplated by this Agreement and to obtain any
additional information that they possess or could reasonably acquire for the
purpose of verifying the accuracy of information furnished to such Stockholder's
or Phantom Stockholder's legal counsel and the Stockholders Representative as
set forth herein or for the purpose of considering the transactions contemplated
hereby. WEI has offered to make available to such Stockholder or Phantom
Stockholder and the Stockholders Representative upon request at any time all

Stockholders Representative have made an independent investigation of the
pertinent facts relating to the transactions contemplated hereby, have reviewed
carefully the terms of this Agreement and the information furnished to such

         HYPOTHECATED OR OTHERWISE TRANSFERRED, EXCEPT UPON REGISTRATION OR
         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.

Such Stockholder or Phantom Stockholder understands and agrees that appropriate
stop transfer notations will be placed in the records of WEI and with its
transfer agents in respect of the Securities that are to be issued to such
Stockholder or Phantom Stockholder. WEI agrees that any Securities sold pursuant
to an effective registration statement, including a registration statement filed
pursuant to Article 12 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 such selling Stockholder or Phantom Stockholder that the sale
was made pursuant to the plan of distribution described in the registration
statement and the prospectus delivery requirements under the Securities Laws
were fully complied with in connection with the sale.

         insolvency, reorganization, moratorium or other similar laws relating

not jointly agree to indemnify, defend and hold WEI (and its subsidiaries,
including Sub, and Affiliates) and the other parties hereto and each of WEI's
and such other parties' officers, directors, employees, agents, stockholders,
affiliates and controlling persons and their respective successors and assigns
harmless from and against and in respect of all Damages directly or indirectly
suffered, incurred or realized by such party or parties, arising out of or
resulting from or relating to, directly or indirectly, any misrepresentation,
breach of warranty or breach of any covenant or agreement made or undertaken by
such Stockholder or Phantom Stockholder in this Agreement or any
misrepresentation in or omission from any other agreement, certificate, exhibit
or writing delivered to WEI by such Stockholder or Phantom Stockholder pursuant
to this Agreement.

         10.2 INDEMNIFICATION BY WEI. Except as otherwise limited by this
Article 10 and Article 11 hereof, WEI agrees to indemnify, defend and hold each
Stockholder and each of their respective officers, directors, employees, agents,
stockholders and controlling Persons and their successors and assigns harmless
from and against and in respect of all Damages directly or indirectly suffered,
incurred or realized by such party, arising out of or resulting from or relating
to, directly or indirectly, any misrepresentation, breach of warranty or breach
of any covenant or agreement made or undertaken by WEI in this Agreement or any
misrepresentation in or omission from any other agreement, certificate, exhibit
or writing delivered to such Stockholder or Phantom Stockholder by WEI pursuant
to this Agreement.

         10.3 NOTICE AND OPPORTUNITY TO DEFEND.

                  (a) If a party seeking indemnification (the "Indemnitee")
becomes aware of any matter that it believes may give rise to an indemnifiable
claim, or asserts any claim that it believes may be indemnifiable pursuant to
Sections 10.1 or 10.2 hereof, the Indemnitee shall give the party obligated to
provide indemnification (the "Indemnifying Party") prompt written notice of such
matter or claim, stating with particularity the nature of such matter or the
aforementioned claim and the amount thereof. 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 Indemnifying Party
that could have been actually avoided had such notice been provided within such
required time period.

                  (b) If the matter that the Indemnitee believes gives rise to
an indemnifiable claim does not involve a third party claim against an
Indemnitee, the Indemnifying Party shall have 30 days from the date on which it
received notice of such claim pursuant to this Section 10.4 hereof to

                                      -17-

<PAGE>   22



respond to such notice. If such Indemnifying Party accepts responsibility or
does not respond within such 30-day period, Indemnifying Party shall promptly
pay to the Indemnitee the full amount of such claim. If the Indemnifying Party
rejects any liability with respect to such claim, it shall give written notice
of such objection to the Indemnitee within such 30-day period and the parties
shall seek to resolve such claim by agreement. If such claim is unable to be
resolved by agreement within 60 days following the expiration of such 30-day
period mentioned above, the parties shall resolve the matter by arbitration
pursuant to Section 13.3 hereof (excluding any requirement in Section 13.3(a)
that the parties attempt to resolve the matter by mutual agreement for a period
of 60 days prior to submitting such matter to arbitration).

                  (c) In the event any action, suit, proceeding or investigation
is brought against the Indemnitee by a third party which the Indemnitee believes
may give rise to an indemnifiable claim pursuant to Section 10.1 or 10.2 hereof,
the Indemnitee shall give the Indemnifying Party prompt written notice of the
commencement of such action, suit, proceeding or investigation as provided in
subsection (a) of this Section 10.4 hereof. Such Indemnifying Party shall have a
period of 30 days after receipt of such notice within which to respond to such
notice. If such Indemnifying Party accepts responsibility, such Indemnifying
Party shall be obligated to compromise or defend such matter, at its own expense
and by counsel chosen by the Indemnifying Party reasonably acceptable to the
Indemnitee. The Indemnitee shall have the right to participate at its own
expense in the defense of such asserted liability. If such Indemnifying Party
does not respond within such 30-day period or rejects responsibility for such
matter in whole or in part, the Indemnitee shall be free to pursue, without
prejudice to any of its rights hereunder, such remedies as may be available to
such party under applicable law. The Indemnitee shall cooperate fully with the
Indemnifying Party and its counsel in the defense against any such asserted
liability. Any compromise of such asserted liability by the Indemnifying Party
shall require the prior written consent of the Indemnitee, which shall not be
unreasonably withheld. If, however, the Indemnitee refuses its consent to a bona
fide offer of settlement which involves solely the payment of cash which the
Indemnifying Party wishes to accept and fully pay subject to the limitations in
Section 10.3(a), the Indemnitee may continue to pursue such matter, free of any
participation by the Indemnifying Party, at the sole expense of the Indemnitee.
In such event, the obligation of the Indemnifying Party to the Indemnitee shall
be equal to the lesser of (i) the amount of the offer of settlement which the
Indemnitee refused to accept plus the costs and expenses of the Indemnitee prior
to the date the Indemnifying Party notifies the Indemnitee of the offer of
settlement, and (ii) the actual out-of-pocket amount the Indemnitee is obligated
to pay as a result of such party's continuing to pursue such matter. An
Indemnifying Party shall be entitled to recover from the Indemnitee any
additional expenses incurred by such Indemnifying Party as a result of the
decision of the Indemnitee to pursue such matter.

         10.4 EXPRESS NEGLIGENCE. THE FOREGOING INDEMNITIES SET FORTH IN THIS
ARTICLE 10 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.

Stockholders and the Phantom Stockholder under Section 10.1 for

         All statements of fact contained in any written statement (including

                               REGISTRATION RIGHTS

         12.1 REGISTRATION RIGHTS.

                  (a) WEI will use its best efforts to register under the
Securities Act the WEI 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, WEI shall file, within 30 Business Days after
the Closing Date, with the Commission a registration statement on the
appropriate form seeking the registration for resale of the WEI Shares (the
"Registration Statement"), pursuant to a non-underwritten offering in accordance
with the plan of distribution described therein. References in this Article 12
to the WEI Shares shall be deemed to include any shares of WEI Common Stock

                                      -20-

<PAGE>   25



or other securities received by the Stockholders or Phantom Stockholder on
account of any stock split, stock dividend or merger of WEI.

                  (b) Notwithstanding anything to the contrary contained in this
Section 12.1, WEI shall not be obligated to prepare and file the Registration
Statement pursuant to this Section 12.1, or prepare or file any amendment or
supplement thereto, at any time when WEI 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 WEI, an acquisition,
merger, recapitalization, consolidation, reorganization or similar transaction
relating to WEI 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 WEI or disclosure of third party
information not readily available to WEI.

                  (c) Notwithstanding anything to the contrary contained in this
Section 12.1, WEI shall be permitted, on written notice to the Stockholders and
Phantom Stockholder, to suspend the period of sale or distribution of the WEI
Shares at any time when WEI reasonably believes that the sale or distribution
thereof would adversely affect a pending or proposed public offering of
securities of WEI, an acquisition, merger, recapitalization, consolidation,
reorganization or similar transaction relating to WEI 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 WEI or disclosure of third party information not readily
available to WEI.

                  (d) The filing of the Registration Statement, or any amendment
or supplement thereto, by WEI may not be deferred pursuant to Section 12.1(b)
hereof, and the sale and distribution of the WEI Shares may not be suspended
pursuant to Section 12.1(c) hereof, for more than 60 days after the abandonment
or consummation (or the completion of the distribution of securities in the case
of a public offering) of any of the proposals or transactions described therein
or, in any event, for more than 150 days.

                  (e) The Stockholders and Phantom Stockholder agree and
covenant to fully cooperate with and assist WEI and its counsel and
representatives in connection with WEI's obligations under this Article 12,
including providing such information as requested by WEI in connection with the
preparation of the Registration Statement and the resale of the WEI Shares.

         12.2 PROCEDURE. WEI will, subject to the provisions of Sections 12.1,
12.2 and 12.4 hereof:

                  (a) seek to cause the Registration Statement to become and
remain effective for a period of up to one year following the Closing Date or
such shorter period of time until the transfer or sale of all the WEI 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 therewith as may be necessary to

                                      -21-

<PAGE>   26



covered by the Registration Statement in accordance with the intended method of
distribution set forth therein;

                  (c) afford the Stockholders and the Phantom Stockholder a
reasonable opportunity to review and comment on drafts of the Registration
Statement and each amendment thereof and supplement thereto, and drafts of each
preliminary prospectus used in connection with the Registration Statement, prior
to their filing or distribution, as the case may be;

                  (d) as expeditiously as reasonably practicable, furnish to the
Stockholders and Phantom Stockholder such number of copies of prospectuses and
preliminary prospectuses in conformity with the requirements of the Securities
Act, and such other documents as the Stockholders and Phantom Stockholder may
reasonably request, in order to facilitate the public sale or other disposition
of the WEI Shares owned by the Stockholders and Phantom Stockholder; provided,
however, that the obligation of WEI to deliver copies of prospectuses or
preliminary prospectuses to the Stockholders and Phantom Stockholder shall be
subject to the receipt by WEI of reasonable assurances from the Stockholders and
Phantom Stockholder that they will comply with the applicable provisions of the
Securities Act and of such other securities laws as may be applicable in
connection with any use by them of any prospectuses or preliminary prospectuses;

                  (e) as expeditiously as practicable, use its best efforts to

reasonably request (considering the nature and size of the offering) and do any
and all other acts and things that may be necessary or desirable to enable the
Stockholders and Phantom Stockholder to consummate the public sale or other
disposition in such jurisdictions of the WEI Shares; provided, however, that WEI
shall not be required to qualify to transact business as a foreign corporation
in any jurisdiction in which it would otherwise not be required to be so
qualified or to take any action that would subject it to general service of
process in any jurisdiction in which it is not then so subject;

                  (f) notify the Stockholders and the Phantom Stockholder
promptly (i) when a prospectus or any prospectus supplement has been filed with
the Commission and, with respect to the Registration Statement or any
post-effective amendment thereto, when such document has been declared effective
by the Commission, (ii) of any request by the Commission for amendments or
supplements to the Registration Statement or related prospectus, or for
additional information, (iii) of the issuance by the Commission of any stop
order or the initiation of any proceedings for such or a similar purpose (and
WEI shall make every reasonable effort to obtain the withdrawal of any such
order as soon as practicable) and (iv) of the receipt by WEI of any notification
with respect to the suspension of the qualification of any of the WEI Shares for
sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose (and WEI shall use commercially reasonable efforts to obtain the
withdrawal of any such suspension as soon as practicable); and

                  (g) bear all Registration Expenses (as defined below) in
connection with the registration hereunder; provided, however, that all Selling
Expenses (as defined below) of the WEI Shares and all fees and disbursements of

expenses incurred by WEI in complying with this Agreement, including (i) all
registration and filing

                                      -22-

for WEI, (iv) all blue sky fees and expenses and (v) all fees and expenses of
accountants for WEI, are herein referred to as "Registration Expenses". All

         12.3 INDEMNIFICATION.

                  (a) In the event of a registration of the WEI Shares under the
Securities Act pursuant to this Agreement, WEI will indemnify and hold harmless
each Stockholder and Phantom Stockholder and any other Person, if any, who
controls such Stockholder or Phantom Stockholder within the meaning of Section
15 of the Securities Act, against any losses, claims, damages or liabilities,
several, to which such Stockholder or Phantom Stockholder 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 WEI 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 WEI assumes the defense as provided in
Section 12.3(c) hereof, promptly following request and receipt of reasonable
supporting documents, such as invoices, reimburse the Stockholders and Phantom
Stockholder 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 WEI 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 all documents incorporated by reference therein, in
reliance upon and in conformity with written information furnished to WEI by or
on behalf of such Stockholder or Phantom Stockholder or a controlling Person
thereof specifically for use in the preparation thereof.

                  (b) In the event of any registration of the WEI Shares under
the Securities Act pursuant to this Agreement, each Stockholder and Phantom
Stockholder will indemnify and hold harmless WEI and each Person, if any, who
controls WEI within the meaning of Section 15 of the Securities Act, each
officer of WEI who signs the Registration Statement and each director of WEI,
against any and all such losses, claims, damages, liabilities or actions that
WEI or such officer, director or controlling Person may become subject under the
Securities Act or otherwise, and will reimburse WEI, each such officer, director
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

                                      -23-

<PAGE>   28



misleading and such statement or omission of a material fact was made in
reliance upon and in conformity with information furnished to WEI by or on
behalf of such Stockholder or Phantom Stockholder 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 such Stockholder's or Phantom Stockholder's failure to
deliver any required prospectus or otherwise comply with applicable laws
regarding the same.

                  (c) Within five days 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 desire, in its sole discretion, 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 that
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 12.3 shall be made
within ten Business Days after notice is sent by the indemnified Person.

         12.4 TERMINATION. If Rule 144 or Rule 145 as promulgated under the
Securities Act or any successor or similar rule or statute shall permit the
public sale of the WEI Shares, the rights to registration provided for in this
Agreement as to the WEI Shares shall terminate immediately.

                                  MISCELLANEOUS

         13.1 ENTIRE AGREEMENT. This Agreement and the other agreements
contemplated hereby constitute the sole understanding of the parties with
respect to the matters provided for herein and supersedes any previous
agreements and understandings between the parties with respect to the subject
matter hereof. No amendment, modification or alteration of the terms or
provisions of this Agreement shall be binding unless the same shall be in
writing and duly executed by WEI and the affected Stockholders or Phantom
Stockholder.

         13.2 SUCCESSORS AND ASSIGNS. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the parties hereto and their
respective successors and assigns. Prior to the Closing Date, this Agreement may
not be assigned by any party without the prior written consent of the other
party hereto, except that WEI may, at its election, assign its rights under this
Agreement to any direct or indirect wholly owned subsidiary or other Affiliate.
Notwithstanding the

                                      -24-

<PAGE>   29



foregoing, no assignment of this Agreement or any of the rights or obligations
hereof by any party, as the case may be, shall relieve such party of its
obligations under this Agreement and, upon any such assignment occurring prior
to the Closing, the representations, warranties, covenants and agreements
contained in this Agreement shall be deemed to have been made by such party's
assignee as well as by such party.

         13.3 ARBITRATION.

                  (a) In the event there shall exist any dispute or controversy
between the parties hereto with respect to this Agreement or any matter relating
hereto or the transactions contemplated hereby, the parties hereto agree to seek
to resolve such dispute or controversy by mutual agreement. If such dispute or
controversy is unable to be resolved by agreement within 60 days following
notice of the nature of such dispute or controversy setting forth in reasonable
detail the circumstances and basis of such dispute or controversy, any party
hereto, as the case may be, may require that such dispute or controversy be
resolved by binding arbitration pursuant to the provisions of this Section 13.3.
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 name 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. Each arbitrator selected to act hereunder shall be qualified by
education and experience to pass on the particular question in dispute. The
arbitrators shall resolve all disputes in controversy in accordance with the
applicable substantive law. All statutes of limitations that would otherwise be
applicable shall apply to any arbitration proceeding.

                  (b) The arbitrators appointed pursuant to this Section 13.3
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.

                  (c) All expenses of arbitration, including reasonable
compensation to the arbitrators, shall be borne equally by the disputing parties
(collectively), as the case may be, except each party shall bear the
compensation and expenses of its own counsel, witnesses and employees.

                  (d) Nothing contained herein shall prohibit any party from
seeking injunctive or other equitable relief pending any decision in arbitration
or from enforcing any order or decision by the arbitrators in any court or other
appropriate forum. For purposes of injunctive relief, orders in aid of
arbitration and entry of the arbitrator's award:

                           (i) each of the parties hereto irrevocably consents
                  to the non-exclusive jurisdiction of, and venue in, any state
                  court located in Harris County, Texas or any federal court

                  [WEATHERFORD INTERNATIONAL, INC. LETTERHEAD]


March 6, 2000


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

Ladies and Gentlemen:

         I am Executive Vice President, Chief Financial Officer and General
Counsel 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 125,941 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
