THE TRANSACTION

     TERMS OF THE TRANSACTION. The Sellers have agreed to sell to Weatherford,
on the Effective Date (as hereinafter defined), all of the assets, contractual

limited to, cash and cash equivalents, contracts, equipment, rental equipment,
goodwill, motor vehicles, real property, shares of the Subsidiaries owned by
Nodeco AS, inventory, intangible property, excess pension plan amounts, accounts

As consideration for the sale of the Assets by the Sellers to Weatherford,

the Sellers the cash amount of NOK 117,649,250 (as adjusted as described below

Nodeco AS 750,000 shares of Weatherford Common Stock.

                                      4

     GOVERNMENTAL AND REGULATORY APPROVAL. On April 2, 1996, Weatherford filed
an application with the Norwegian Ministry of Industry and Energy (the

Business Act of 1994. The required 30-day waiting period will expire on May 2,
1996, unless the Ministry requests further information. See "The Transaction --
Governmental and Regulatory Approvals". Weatherford and the Sellers are aware of
no other material governmental or regulatory approvals required for consummation
of the Transaction.

     CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES.  Certain non-United States
holders of Weatherford Common Stock may be subject to federal income or estate
tax consequences due to their ownership and disposition of Weatherford Common
Stock. See "The Transaction -- Certain U.S. Federal Income Tax Consequences to
Non-United States Holders".

     ACCOUNTING TREATMENT. The Transaction will be accounted for using the

first business day after any such stop order has been removed; (iii) the fifth
Norwegian business day after Weatherford has notified the Sellers in writing of
Ministry Approval (as hereinafter defined), unless Ministry Approval has been
waived by Weatherford, in its sole discretion; and (iv) the approval of the
shareholders of each Seller of the Transaction.

     ADJUSTMENTS TO CONSIDERATION. The cash portion of the Purchase Price will
be adjusted to account for movements in the price of Weatherford Common Stock on
the New York Stock Exchange (the "NYSE") and the exchange rate between United
States dollars and Norwegian kroner from the date of the Purchase and Sale
Agreement to the Effective Date, subject to certain limitations. Under certain
circumstances, the Sellers shall be entitled to interest on the purchase price
for the Assets. Weatherford is permitted under certain circumstances to reduce
the purchase price for the Assets for any representations and warranties made by
the Sellers in the Purchase and Sale Agreement that are untrue, inaccurate,
misleading or breached. See "Terms of the Transaction -- Adjustments to
Consideration".

     CONDITIONS TO CLOSING OF THE TRANSACTION. Pursuant to the Purchase and Sale
Agreement, the closing of the Transaction is subject to certain conditions,
including (i) the approval of the Transaction by the requisite vote of the
shareholders of each Seller as may be required under Norwegian law or such
Seller's governing documents, (ii) Ministry Approval, unless Weatherford, in its
sole discretion, waives such requirement, (iii) the declaration of the
effectiveness of the Registration Statement by the Commission and the lack of
any stop orders suspending the effectiveness of the Registration Statement, (iv)
the delivery to Weatherford of guarantees executed by certain shareholders of
Nodeco AS and (v) the delivery to Weatherford by the Sellers of certain bills of
sale, deeds, assignments and other documents regarding the Assets.

     TERMINATION OR AMENDMENT OF PURCHASE AND SALE AGREEMENT. The Purchase and
Sale Agreement may be amended or supplemented only by an instrument in writing
signed on behalf of Weatherford and each Seller. The Sellers have the right to
terminate the Purchase and Sale Agreement if, prior to May 27, 1996, either (i)
the Commission has not declared the Registration Statement effective and all
stop orders have not been removed or (ii) Weatherford has not obtained Ministry
Approval, unless, in its sole discretion, Weatherford has waived such
requirement. If the Sellers do not exercise such right within five business days
following May 27, 1996, and an event referred to in either clause (i) or clause
(ii) above has not occurred prior to July 26, 1996, Weatherford or either Seller
may terminate the Purchase and Sale Agreement within five business days
following such date.

                                      5

     INDEMNIFICATION. The Purchase and Sale Agreement provides for
indemnification by the Sellers to Weatherford and the Subsidiaries against
Losses (as hereinafter defined) related to untrue, inaccurate, misleading or
breached representations or warranties made by the Sellers in the Purchase and
Sale Agreement and related to tax claims not included in the Nodeco Accounts (as
hereinafter defined). The Purchase and Sale Agreement provides for
indemnification by Weatherford to the Sellers against Losses related to (i)

the contracts being transferred to Weatherford as part of the Transaction, (v)
failure by Weatherford to satisfy the liabilities being assumed by it as part of
the Transaction and (vi) tax claims made against Nodeco before the Effective
Date. See "Terms of the Transaction -- Indemnification".

     NON-COMPETITION AGREEMENT. In the Purchase and Sale Agreement, the Sellers
have agreed that, for a period of two years following the Effective Date,
neither the Sellers nor any affiliate of the Sellers will compete, directly or
indirectly, with Weatherford or any affiliate of Weatherford in designing,
manufacturing, selling, renting or running liner hangers, packers and gas lift
valves and systems. The Sellers also have agreed on behalf of the Sellers and
their affiliates not to solicit for employment any employee of Weatherford or
any affiliate of Weatherford, including any employee of either Seller or any
Subsidiary who becomes an employee of Weatherford or any affiliate of
Weatherford.

COMPARATIVE RIGHTS OF THE STOCKHOLDERS OF WEATHERFORD AND NODECO AS

     Upon consummation of the Transaction, Nodeco AS will be a holder of shares
of Weatherford Common Stock. To the extent the shares of Weatherford Common
Stock held by Nodeco AS are distributed to the shareholders of Nodeco AS, in
connection with a liquidation of Nodeco AS or otherwise, holders of shares of
Nodeco AS will become holders of shares of Weatherford Common Stock. The shares
of Nodeco AS are governed by Norwegian law and the Articles of Association of
Nodeco AS. The rights of holders of Weatherford Common Stock are governed by the
law of the State of Delaware, Weatherford's Restated Certificate of
Incorporation and Weatherford's Bylaws. There are various differences between
the rights of shareholders of Nodeco AS and the rights of Weatherford
stockholders, including, among other things, the required vote for certain
business combinations and other significant matters. Furthermore, Weatherford's
Restated Certificate of Incorporation contains certain provisions that may have
the effect of deterring or making it more difficult for a third party to acquire
control of Weatherford. See "Comparative Rights of Stockholders of Weatherford
and Nodeco AS".

     As of March 27, 1996, the last trading day prior to the announcement by
Weatherford and Nodeco AS that they had reached an agreement concerning the
Transaction, the closing sale price of Weatherford Common Stock as reported by
the NYSE was $35.63 per share.

                                      8

                                 RISK FACTORS

     NONPAYMENT OF DIVIDENDS.  Weatherford has not declared or paid dividends
on the Weatherford Common Stock since December 1982 and does not anticipate
paying dividends on the Weatherford Common Stock at any time in the
foreseeable future.

     INDUSTRY VOLATILITY.  The oil and gas industry in which Weatherford and
Nodeco participate historically has experienced significant volatility. Demand
for Weatherford's and Nodeco's services and products depends primarily upon
the number of oil and gas wells being drilled, the depth and drilling
conditions of such wells, the volume of production, the number of well
completions and the level of workover activity. Drilling and workover activity
can fluctuate significantly in a short period of time, particularly in the
United States and Canada.

     The willingness of oil and gas operators to make capital expenditures for
the exploration and production of oil and natural gas will continue to be
influenced by numerous factors over which Weatherford and Nodeco have no
control, including the prevailing and expected market prices for oil and
natural gas. Such prices are impacted by, among other factors, the ability of
the members of the Organization of Petroleum Exporting Countries ("OPEC") to
maintain price stability through voluntary production limits, the level of
production by non-OPEC countries, worldwide demand for oil and gas, general
economic and political conditions, costs of exploration and production,
availability of new leases and concessions, and governmental regulations
regarding, among other things, environmental protection, taxation, price
controls and product allocations. No assurance can be given as to the level of
future oil and gas industry activity or demand for Weatherford's and Nodeco's
services and products.

     COMPETITION.  Weatherford encounters substantial competition from
numerous small, single-site operators, larger concerns operating at multiple
locations and various well servicing companies. In addition, Nodeco encounters
substantial competition from several large companies that operate in the
Norwegian and United Kingdom sectors of the North Sea. Weatherford expects
that the substantial competition currently encountered by it and Nodeco will
not be reduced or eliminated if the Transaction is consummated.

     POSSIBLE PRODUCT LIABILITY CLAIMS.  Certain products manufactured or
leased by Weatherford or Nodeco are used in potentially hazardous drilling,
completion, production and workover applications that can cause personal
injury or loss of life as well as damage to property, equipment or the
environment and suspension of operations. Litigation arising from a
catastrophic occurrence at a location where Weatherford's or Nodeco's
equipment and services are used may in the future result in Weatherford or
Nodeco being named as a defendant in product liability or other lawsuits
asserting potentially large claims. Each of Weatherford and Nodeco maintains
insurance coverage that its management believes to be customary in the
industry for a company of its size against these hazards. However, insurance
may not provide complete protection against casualty losses and a successful
claim could have a material adverse effect on Weatherford or Nodeco. Further,
no assurance can be given that Weatherford or Nodeco will be able to maintain
adequate insurance in the future at rates considered reasonable.

     RISKS RELATED TO INTERNATIONAL OPERATIONS.  During 1995, approximately
53% of Weatherford's revenues were derived from sales and rentals outside of
the United States and Canada based upon the ultimate destination in which
equipment or services were sold, shipped or provided to the customer. Certain
of these operations are subject to special risks inherent in doing business
outside the United States, including risks of war, civil disturbances and
governmental activities that may limit or disrupt markets, restrict the
movement of funds or result in the deprivation of contract rights or the
taking of property without fair compensation. Certain areas, including
Algeria, Nigeria, Angola and parts of the Middle East have been subjected to
political disruption or social unrest in the past twelve months. International
operations also can be affected by laws and regulations limiting or
prohibiting exports to and operations in particular countries, including Iran,
Iraq and Libya. Government-owned petroleum companies in some of the countries
in which Weatherford operates have adopted policies (or are subject to
governmental policies) giving preference to the purchase of goods and services
from companies that are majority-owned by local nationals. As a result of such
policies, Weatherford relies on joint ventures, license arrangements and other
business combinations with local nationals in these countries. In addition,
political considerations may

                                      9

disrupt the commercial relationships between Weatherford and government-owned
petroleum companies. Generally, business interruptions resulting from civil or
political disruptions negatively impact near-term results of operations;
however, management of Weatherford believes that it is unlikely that any
specific business disruption caused by existing or foreseen civil or political
instability will have a materially adverse impact on the financial condition
or liquidity of Weatherford. Weatherford expects that the risks encountered by
it in its international operations also would apply to Nodeco if the
Transaction is consummated.

     GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS.  Weatherford's and
Nodeco's businesses are affected both directly and indirectly by governmental
regulations relating to the oilfield service industry and the oil and gas
exploration and production industry in general, as well as by environmental
and safety regulations that specifically apply to such businesses. It is
likely that the trend of more expansive and stricter environmental laws and
regulations will continue, and that the costs of compliance with such laws and
regulations will continue to increase in the foreseeable future, for
Weatherford, Nodeco and their customers. There can be no assurance that the
cost of compliance with current environmental and safety regulations or future
changes in such laws and regulations will not have a material adverse effect
on Weatherford's and Nodeco's operations.

                              EXCHANGE RATE DATA

     The following table sets forth, for the periods indicated, certain
exchange rates based on the high and low noon buying rates in New York City
for cable transfers in foreign currencies as certified for customs purposes by
the Federal Reserve Bank of New York. The rates quoted are the number of
United States dollars per one NOK. The average exchange rate is based on the
average of the exchange rates on the last day of each month during such
periods. On April 12, 1996, the exchange rate based on the noon buying rate in
New York City for cable transfers of NOK expressed in United States dollars,
as certified for customs purposes by the Federal Reserve Bank of New York, was
$0.1540 per one NOK.

                          WEATHERFORD ENTERRA, INC.

     Weatherford is a diversified international energy service and
manufacturing company that provides a variety of services and equipment to the
exploration, production and transmission sectors of the oil and gas industry.
Weatherford's principal business segments include (i) the oilfield services
segment, which consists of renting specialized oilfield equipment, providing
fishing, well control assistance and other downhole services and related
tools, and providing tubular running services and related tools; (ii) the
energy products and services segment, which consists of manufacturing, selling
and servicing a variety of products, including cementation products, power
equipment, fishing and milling tools and heavy wall drill pipe, gas lift
valves, production and service packers and related equipment, electrical and
instrumentation control systems and pedestal-mounted marine cranes; (iii) the
gas compression segment, which consists of manufacturing, packaging, selling,
renting and servicing reciprocating natural gas compressors; and (iv) the
pipeline services segment, which consists of manufacturing, selling and
renting specialized pipeline equipment and services. Weatherford operates in
virtually every oil and gas exploration and production region in the world,
with more than 330 locations in 47 countries, including the United States.

                                      10

                                    NODECO

     Nodeco designs, manufactures, sells and rents oil and gas well completion
products primarily consisting of liner hanger equipment and related services,
as well as packers used in completions with electric submersible pumps.
Nodeco's primary markets for these products are the Norwegian and United
Kingdom sectors of the North Sea. Nodeco also provides products and services
for reservoir and wellbore monitoring and manufactures precision mechanical
components for customers that are primarily affiliated with the oil industry.

     Liner hanger equipment is used in the drilling and completion of oil and
gas wells. While primarily used for the production casing string in deep,
deviated or horizontal wells, liner hangers also may be used for intermediate
casing sections of a well. Nodeco provides a broad range of liner hanger
equipment in diameters ranging from 4 1/2 inches to 18 5/8 inches. A variety
of accessories and configurations also are available including rotating and
non-rotating liner hangers, single and dual wiper plug systems, liner top
packers and installation and clean-out tools. Equipment is designed by Nodeco
to meet North Sea standards for the industry. In most situations, Nodeco
supplies a complete liner hanger package to the customer including Nodeco
liner hanger equipment and running tools, as well as cementing equipment
purchased from third parties, all of which are assembled and tested before
shipping to the customer. Nodeco employees also act as advisors at the
drilling rig when the equipment is installed. Two special products that Nodeco
markets as part of its liner hanger system are the Floating Junk Bonnet and
the Top-Drive Cementing Head. The Floating Junk Bonnet is a Nodeco innovation
(patents pending) that keeps debris from entering the liner hanger equipment
when it is being installed. The tool helps prevent sticking in the wellbore
and improves the setting performance of the liner hanger. The Top-Drive
Cementing Head is an attachment that allows the liner to be rotated by the Top
Drive System during cementing, thereby improving the cementation of the liner.

     Electric submersible pump installations commonly are used in producing
wells in the United Kingdom sector of the North Sea as well as in numerous
other oil fields worldwide. Most of these completions use a packer to improve
the completion and the efficiency of the pump. Pump packers are
hydraulically-set, multiple-string tools that provide for production tubing
string, power cable, gas venting, gas or chemical injection and wireline
instrument access. The pump packers are retrievable to allow for frequent
workovers associated with electric submersible pumps. In 1990, Nodeco worked
jointly with BP Exploration to develop a proprietary resettable pump packer
that could be set, released and then reset to reduce workover costs. The
patented tool design allows near surface repairs to the power cable system
without requiring the pump packer to be retrieved to the surface, thereby
significantly reducing rig time and workover cost. Nodeco's patented "RR"
Resettable Pump Packer presently is manufactured in four main sizes ranging
from 7 inches to 13 3/8 inches, with up to five string capacity. Typically,
the pump packers are manufactured with 13% chrome materials, and a variety of
design modifications are available. Additional sizes are designed as customers
request them. Pump packers generate additional service revenues each time they
are retrieved from the well and require redressing and repair. As an addition
to the pump packer line, Nodeco recently developed a retrievable sump packer
that can be run in tandem with the pump packer.

     Nodeco has a working relationship with a German manufacturer that has a
proprietary manufacturing process to produce a screen system to be used across
producing intervals. This special screen system allows the operator to
eliminate gravel packing as part of the completion process. The resulting well
completion produces with less differential pressure and has improved flow
characteristics.

     Aarbakke, a wholly-owned subsidiary of Nodeco AS, is a manufacturing unit
that also provides precision machining services to third parties in Norway and
other countries. These services generally consist of manufacturing small and
large mechanical components. Approximately half of Aarbakke's production
capacity is used for third-party manufacturing, of which 80% relates to oil
industry activities.

     Subsurface Technology AS, a 51% owned subsidiary of Nodeco AS
("SubTech"), provides consulting services related to production and reservoir
monitoring activities, as well as design, fabrication and installation of
systems for such activities. Systems designed and fabricated by SubTech for
customers have included downhole pressure and temperature monitoring equipment
and the associated surface data

                                      11

acquisition equipment. Consulting studies performed by SubTech for customers
have evaluated the feasibility of various temperature and pressure monitoring
systems, reservoir subsidence monitoring, selective well stimulation
procedures and other concepts related to fluid measurement and other
production applications. SubTech's customers include many of the active
operators in the Norwegian sector of the North Sea, as well as other foreign
entities.

     Historically, Nodeco has focused its marketing efforts on the North Sea
market, and Nodeco only recently has increased its international sales
efforts. Nodeco actively provides liner hanger equipment and services in all
sectors of the North Sea as well as certain other parts of the world. Until
recently, substantially all of Nodeco's pump packer sales have been to
operators in the United Kingdom sector of the North Sea, since no electric
submersible pump completions had been made in the Norwegian sector. Nodeco has
made recent sales of pump packers to certain Norwegian producers. Most of
Nodeco's machining services and reservoir monitoring consulting services are
provided to Norwegian customers. Nodeco's revenues derived from non-North Sea
markets originate primarily from other European countries, North and West
Africa and the Asia-Pacific region.

                               THE TRANSACTION

     The detailed terms and conditions to the consummation of the Transaction
are contained in the Purchase and Sale Agreement, which is attached as
Appendix A to this Prospectus and is incorporated herein by reference. The
following discussion sets forth a description of certain material terms and
conditions of the Purchase and Sale Agreement. THE DESCRIPTION IN THIS
PROSPECTUS OF THE TERMS AND CONDITIONS TO THE CONSUMMATION OF THE TRANSACTION
IS QUALIFIED BY, AND MADE SUBJECT TO, THE MORE COMPLETE INFORMATION SET FORTH
IN THE PURCHASE AND SALE AGREEMENT.

GENERAL DESCRIPTION OF THE TRANSACTION

     The Sellers have agreed to sell to Weatherford on the Effective Date the
Assets, consisting of all of the assets, contractual rights and business of
the Sellers at the Effective Date, including, but not limited to, cash and
cash equivalents, the benefits of the Sellers' outstanding contractual
obligations, equipment, rental equipment, goodwill, motor vehicles, real
property, shares of the Subsidiaries owned by Nodeco AS, inventory, intangible
property, all amounts allocated to the Sellers' collective pension plan as of
the Effective Date in excess of the liability under such plan as of the
Effective Date, accounts receivable, prepayments and existing legal claims. As
consideration for the sale of the Assets by the Sellers to Weatherford,
Weatherford will assume all liabilities of the Sellers (other than Net Debt in
excess of NOK 32 million), pay to the Sellers the cash amount of NOK
117,649,250 (as adjusted as described below under "Terms of the
Transaction -- Adjustments to Consideration") and issue to Nodeco AS 750,000
shares (the "Consideration Shares") of Weatherford Common Stock. The term "Net
Debt" is defined in the Purchase and Sale Agreement to mean the sum of
Nodeco's bank overdrafts, other short-term interest bearing liabilities,
mortgage and other long-term debt and subordinated loans less any cash and
cash equivalents as listed in the audited financial statements of Nodeco AS,
Aarbakke, each Subsidiary and Nodeco AS on a consolidated basis, in each case
at December 31, 1995 (collectively, the "Nodeco Accounts"). Weatherford has
agreed to offer each employee of the Sellers a similar position on similar
terms as that held at the Effective Date. In addition, Weatherford has agreed
to use its best efforts to list the Consideration Shares on the NYSE.

GOVERNMENTAL AND REGULATORY APPROVALS

     The Transaction is subject to (i) the receipt of approval from the
Norwegian Ministry of Industry and Energy (the "Ministry") under the Norwegian
Acquisition of Business Act of 1994 ("NABA") without conditions that
materially alter the economic value to Weatherford of the Transaction or (ii)
the expiration of the applicable 30-day waiting period without a request by
the Ministry for further information (either (i) or (ii) referred to as
"Ministry Approval"), unless Weatherford, in its sole discretion, waives the
requirement of Ministry Approval. Transactions such as the Transaction are
reviewed by the Ministry to determine if the acquisition may have material
adverse effects, including employment effects, on a

                                      12

company, its line of business or society as a whole. Weatherford filed an
application for Ministry approval on April 2, 1996. The required waiting
period under NABA will expire on May 2, 1996, unless the Ministry requests
further information.

     Weatherford shall be entitled to terminate the Purchase and Sale
Agreement if Ministry Approval is not obtained, unless Weatherford, in its
sole discretion, waives the requirement of Ministry Approval. There can be no
assurance that the Ministry will not require further information in connection
with the Transaction or that the Ministry will approve the Transaction without
conditions that materially alter the economic value of the Transaction to
Weatherford.

     Weatherford and the Sellers are aware of no other material governmental
or regulatory approvals required for consummation of the Transaction.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS

     The following is a general discussion of certain United States federal
income and estate tax consequences of the ownership and disposition of
Weatherford Common Stock by non-United States holders. The following
discussion does not purport to be a complete analysis of all of the potential
tax considerations relating thereto. This discussion is based upon the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations,
United States Internal Revenue Service ("IRS") rulings and judicial decisions
now in effect, all of which are subject to change (possibly with retroactive
effect) or different interpretations. This discussion does not purport to deal
with all aspects of federal income and estate taxation that may be relevant to
a particular non-United States holder's decision to own Weatherford Common
Stock. Neither Weatherford nor Nodeco has requested an opinion of legal
counsel or an IRS ruling regarding the federal income or estate tax
consequences of the ownership or disposition of Weatherford Common Stock by
non-United States holders. PROSPECTIVE NON-UNITED STATES HOLDERS OF
WEATHERFORD COMMON STOCK ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS
REGARDING THE UNITED STATES FEDERAL, STATE AND LOCAL AND NON-UNITED STATES TAX
CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF WEATHERFORD
COMMON STOCK.

     As used herein, "non-United States holder" means a corporation,
individual or partnership that is, as to the United States, a foreign
corporation, a non-resident alien individual or a foreign partnership, or any
estate or trust that is not subject to United States taxation on income from
sources outside the United States and that is not effectively connected with
the conduct of a trade or business within the United States.

     Dividends paid to a non-United States holder of Weatherford Common Stock
will be subject to withholding of United States federal income tax at a 30%
rate or such lower rate as may be specified by an applicable income tax
treaty. The United States federal income tax withholding rate on dividends
paid to a non-United States holder is limited to 15% under Article 8 of the
Norway-United States Income Tax Treaty (the "Treaty") provided the non-United
States holder (i) is a resident of Norway, within the meaning of the Treaty,
and (ii) does not have a permanent establishment in the United States with
respect to which the dividends are effectively connected. Under currently
effective Treasury Regulations, dividends paid to an address in a foreign
country are presumed to be paid to a resident of the country in determining
the applicability of a treaty for those purposes. Proposed Treasury
Regulations, if finally adopted, would require a non-United States holder to
file certain forms to obtain the benefit of any applicable tax treaty
providing for a lower rate of withholding tax on dividends. Those forms would
contain the holder's name and address and, subject to a de minimis exception,
an official statement by the competent authority in the foreign country (as
designated in the applicable tax treaty) attesting to the holder's status as a
resident thereof. However, except as may be otherwise provided in an
applicable income tax treaty, a non-United States holder will be taxed at
ordinary federal income tax rates (on a net income basis) on dividends that
are effectively connected with the conduct of a trade or business of the
non-United States holder within the United States and will not be subject to
the withholding tax described above. Certain certification requirements must
be complied with to claim an exemption from withholding on effectively
connected dividends. If the non-United States holder is a foreign corporation,
it also may be subject to a United States

                                      13

branch profits tax at a 30% rate or such lower rate as may be specified by an
applicable income tax treaty on effectively connected dividends. A non-United
States holder that is eligible for a reduced rate of United States withholding
tax pursuant to an income tax treaty may apply for a refund of any excess
amounts withheld by filing an appropriate claim for refund with the IRS.
Weatherford has not declared or paid dividends on Weatherford Common Stock
since December 1982 and does not anticipate paying dividends on Weatherford
Common Stock at any time in the foreseeable future.

     Non-United States holders generally will not be subject to United States
federal income tax in respect of gain recognized on a disposition of
Weatherford Common Stock unless (i) the gain is effectively connected with a
trade or business conducted by the non-United States holder within the United
States (in which case the branch profits tax described in the preceding
paragraph also may apply if the holder is a foreign corporation), (ii) in the
case of a non-United States holder who is a non-resident alien individual and
holds Weatherford Common Stock as a capital asset, the holder is present in
the United States for 183 or more days in the taxable year of the disposition
and certain other conditions are met, (iii) the non-United States holder is
subject to tax pursuant to the provisions of the United States federal tax law
applicable to certain United States expatriates or (iv) Weatherford is or has
been a "United States real property holding corporation" for federal income
tax purposes and, if Weatherford Common Stock is considered "regularly traded"
during the year of the disposition of Weatherford Common Stock, the non-United
States holder held directly or indirectly at any time during the five-year
period ending on the date of disposition more than five percent of the
outstanding Weatherford Common Stock. Generally, this last rule for stock in
United States real property holding corporations takes precedence over relief
provided by tax treaties. However, non-United States holders who would be
subject to United States federal income tax with respect to gain recognized on
a sale or other disposition of Weatherford Common Stock should consult
applicable treaties, which may provide different rules.

     Weatherford Common Stock that is owned or treated as being owned at the
time of death by a non-United States holder who is a non-resident alien
individual will be included in the holder's gross estate for United States
federal estate tax purposes, unless an applicable estate tax treaty provides
otherwise.

     Generally, dividends paid to non-United States holders outside the United
States that are subject to the 30% or treaty-reduced rate of withholding tax
will be exempt from the 31% backup withholding tax. As a general matter,
information reporting and backup withholding will not apply to a payment by or
through a foreign office of a foreign broker of the proceeds of a sale of
Weatherford Common Stock effected outside the United States. However,
information reporting requirements (but not backup withholding) will apply to
a payment by or through a foreign office of a broker of the proceeds of a sale
of Weatherford Common Stock effected outside the United States where that
broker (i) is a United States person, (ii) is a foreign person that derives
50% or more of its gross income for certain periods from the conduct of a
trade or business in the United States or (iii) is a "controlled foreign
corporation" as defined in the Code (generally, a foreign corporation
controlled by United States shareholders), unless the broker has documentary
evidence in its records that the holder is a non-United States holder and
certain conditions are met or the holder otherwise establishes an exemption.
Payment by a United States office of a broker of the proceeds of a sale of
Weatherford Common Stock is subject to both backup withholding and information
reporting unless the holder certifies to the payor in the manner required as
to its non-United States status under penalties of perjury or otherwise
establishes an exemption.

     Amounts withheld under the backup withholding rules do not constitute a
separate United States federal income tax. Rather, any amounts withheld under
the backup withholding rules will be allowed as a refund or credit against the
holder's United States federal income tax liability, if any, provided the
required information or appropriate claim for refund is filed with the IRS.

ACCOUNTING TREATMENT

     The Transaction will be accounted for using the purchase method of
accounting. Consequently, the results of operations of Nodeco will be included
with those of Weatherford from the Effective Date.

                                      14

                           TERMS OF THE TRANSACTION

EFFECTIVE DATE OF THE TRANSACTION

     The Purchase and Sale Agreement provides that the Transaction will become
effective (the "Effective Date") on such date as the Sellers and Weatherford
may agree or upon the latest to occur of the following events: (i) the fifth
business day after Weatherford has notified the Sellers in writing that the
Commission has declared the Registration Statement effective under the
Securities Act, provided that no stop order is in effect on such day; (ii) the
first business day after any such stop order has been removed; (iii) the fifth
Norwegian business day after Weatherford has notified the Sellers in writing
of Ministry Approval, unless Ministry Approval has been waived by Weatherford,
in its sole discretion; and (iv) the approval of the Transaction by the
shareholders of each Seller.

ADJUSTMENTS TO CONSIDERATION

     Subject to the adjustments described below, the purchase price (the
"Purchase Price") for the Assets shall consist of cash consideration of NOK
117,649,250 and the issuance to Nodeco AS of 750,000 shares of Weatherford
Common Stock. The cash portion of the Purchase Price will be adjusted to
account for movements in the price of Weatherford Common Stock on the NYSE and
the exchange rate between United States dollars and Norwegian kroner from the
date of the Purchase and Sale Agreement to the Effective Date, subject to
certain limitations. The adjustment to the cash consideration shall be made
according to the following formula:

       NOK 142,350,750 - (Average Stock Price x 750,000 x Exchange Rate)

If the adjustment referred to above is a positive number, the cash
consideration will be increased by an amount equal to such positive number. If
the adjustment referred to above is a negative number, the cash consideration
will be reduced by an amount equal to such negative number. The term "Average
Stock Price" is defined as the average Weatherford Common Stock closing price
on the NYSE as reported by The Wall Street Journal for the ten business days
ending on the last business day prior to the Effective Date; provided, that
(i) if the average Weatherford Common Stock closing price for the ten business
days ending on the last business day prior to the Effective Date is greater
than $35 per share, then the "Average Stock Price" shall be exactly $35 per
share, (ii) if the average Weatherford Common Stock closing price for the ten
business days ending on the last business day prior to the Effective Date is
less than $25 per share, then the "Average Stock Price" shall be exactly $25
per share, and (iii) if the average Weatherford Common Stock closing price for
the ten business days ending on the last business day prior to the Effective
Date is less than $20 per share, then Weatherford shall have the option to
terminate the Purchase and Sale Agreement or pay an amount of additional cash
consideration equal to the product of (A) the amount by which $20 exceeds the
average Weatherford Common Stock closing price for the ten business days
ending on the last business day prior to the Effective Date and (B) 750,000
and (C) the Exchange Rate. The term "Exchange Rate" is defined as the average
NOK/United States dollar exchange rate as reported by Dagens Naeringsliv for the
ten business days ending on the last business day prior to the Effective Date;
provided, that (i) if the average NOK/United States dollar exchange rate for
the ten business days ending on the last business day prior to the Effective
Date is greater than NOK 6.4532 per United States dollar, then the "Exchange
Rate" shall be exactly 6.4532, and (ii) if the average NOK/United States
dollar exchange rate for the ten business days ending on the last business day
prior to the Effective Date is less than NOK 6.2002 per United States dollar,
then the "Exchange Rate" shall be exactly 6.2002.

     The Sellers shall be entitled to interest on the Purchase Price at the
rate of five percent per annum for the period beginning on the sixth business
day after the Commission has declared the Registration Statement effective and
ending on the earlier to occur of (i) the last business day prior to the
Effective Date and (ii) May 27, 1996. If the Effective Date has not taken
place before May 27, 1996 and the Sellers do not exercise their option to
terminate the Purchase and Sale Agreement described under "-- Termination or
Amendment of Purchase and Sale Agreement", the Sellers shall be entitled to
interest on the Purchase Price at the rate of ten percent per annum for the
period beginning on May 28, 1996 and ending on the last business day prior to
the Effective Date.
                                      15

     If any representations and warranties provided by the Sellers to
Weatherford in the Purchase and Sale Agreement (including that the Sellers
have, to the best of their knowledge, provided all information relating to the
Sellers and the Subsidiaries and their respective affairs that would be
material to Weatherford for the valuation of the Assets and the business of
the Sellers) are untrue, inaccurate, misleading or breached, Weatherford shall
be entitled to reduce the cash portion of the Purchase Price by an amount (the
"Deficiency Amount") equal to the value at the Effective Date of the specific
Assets (or portions thereof) or specific assumed liabilities (or portions
thereof) that resulted in the representations and warranties being untrue,
inaccurate, misleading or breached; provided, that if the Deficiency Amount is
greater than NOK 44,000,000, Weatherford and the Sellers shall use their
reasonable best efforts to reach an agreement with respect to the Transaction
on mutually acceptable terms, or, after failure to reach such an agreement
within ten business days, any party shall be permitted to terminate the
Purchase and Sale Agreement. If any representations and warranties provided by
the Sellers to Weatherford in the Purchase and Sale Agreement are discovered
after the Effective Date to have been untrue, inaccurate, misleading or
breached at the Effective Date, the Sellers shall reimburse to Weatherford the
Deficiency Amount plus interest on such amount at the rate of eight percent
per annum from the Effective Date to the date of reimbursement.

CONDITIONS TO CLOSING OF THE TRANSACTION

     Pursuant to the Purchase and Sale Agreement, the closing of the
Transaction is subject to certain conditions, including (i) the approval of
the Transaction by the requisite vote of the shareholders of each Seller as
may be required under Norwegian law or such Seller's governing documents, (ii)
Ministry Approval, unless Weatherford, in its sole discretion, waives such
requirement, (iii) the declaration of the effectiveness of the Registration
Statement by the Commission and the lack of any stop orders suspending the
effectiveness of the Registration Statement, (iv) the delivery of guarantees
in favor of Weatherford executed by certain shareholders of Nodeco AS and (v)
the delivery to Weatherford by the Sellers of certain bills of sale, deeds,
assignments and other documents regarding the Assets.

REPRESENTATIONS AND WARRANTIES OF WEATHERFORD AND THE SELLERS

     In the Purchase and Sale Agreement, the Sellers have made various
representations and warranties relating to, among other things, their
businesses, properties and financial conditions, the accuracy of their
financial statements, the ownership of their assets, their compliance with
certain laws (including environmental) and permitting requirements, the status
of their contracts and the existence or absence of certain litigation. In the
Purchase and Sale Agreement, Weatherford has made various representations and
warranties relating to, among other things, its business and financial
condition, the accuracy of its recent filings with the Commission and its
financial statements contained therein, its compliance with certain laws and
permitting requirements and the existence or absence of certain litigation.

CONDUCT OF SELLERS' BUSINESS PRIOR TO THE TRANSACTION

     Pursuant to the Purchase and Sale Agreement, the Sellers have agreed
that, from the date of the Purchase and Sale Agreement to the Effective Date,

(xix) give full access to Weatherford at all reasonable times to the premises
and records of the Sellers and the Subsidiaries and furnish information
regarding the business of the Sellers and the Subsidiaries as requested by
Weatherford.

TERMINATION OR AMENDMENT OF PURCHASE AND SALE AGREEMENT

     The Purchase and Sale Agreement may be amended or supplemented only by an
instrument in writing signed on behalf of Weatherford and each Seller. The
Sellers have the right to terminate the Purchase and Sale Agreement if, prior
to May 27, 1996, either (i) the Commission has not declared the Registration
Statement effective and all stop orders have not been removed or (ii)
Weatherford has not obtained Ministry Approval, unless, in its sole
discretion, Weatherford has waived such requirement. The Sellers may only
exercise such right of termination within five business days following May 27,
1996. If such right is not exercised, and an event referred to in either
clause (i) or clause (ii) above has not occurred prior to July 26, 1996,
Weatherford or either Seller may terminate the Purchase and Sale Agreement
within five business days following such date.

INDEMNIFICATION

     The Purchase and Sale Agreement provides that the Sellers shall indemnify
and hold harmless Weatherford and the Subsidiaries for one year following the
Effective Date against all losses, claims, damages, liabilities, costs and
other expenses ("Losses") it or any Subsidiary may reasonably incur or become
subject to in connection with third party claims against Weatherford or any
Subsidiary related to events that occurred prior to the Effective Date, to the
extent such claim has not resulted in a reduction of the cash portion of the
Purchase Price by, or a reimbursement by the Sellers to Weatherford of, a
Deficiency Amount and to the extent such Losses arise out of, are based upon
or are in connection with any untrue, inaccurate, misleading or breached
representation or warranty made by the Sellers in the Purchase and Sale
Agreement. In addition, the Sellers shall indemnify and hold harmless
Weatherford and the Subsidiaries for a period of three years after the
Effective Date against all Losses they may reasonably incur or become subject
to, insofar as such Losses arise out of, are based upon or are in connection
with a claim by any taxing authority for any taxes allocated or attributable
to any period ending on or before December 31, 1995 that has not been included
in the Nodeco Accounts. The Sellers shall only be responsible for tax Losses
in excess of NOK 1,000,000 and for all other Losses in excess of NOK
4,000,000. The Sellers' maximum liability for all such Losses shall not exceed
NOK 75,000,000. Pursuant to the Purchase and Sale Agreement, certain
shareholders of Nodeco AS will guarantee the Sellers' indemnification
obligations.

     The Purchase and Sale Agreement provides that Weatherford shall indemnify
and hold harmless the Sellers against all Losses they may reasonably incur or
become subject to under the Securities Act, the Exchange Act or otherwise,
insofar as such Losses arise out of, are based upon or are in connection with
(i) any untrue, inaccurate misleading or breached representation or warranty
made by Weatherford in the Purchase and Sale Agreement, (ii) any untrue
statement or omission of a material fact (or alleged untrue statement or
omission) contained in the Registration Statement or any prospectus included
therein, (iii) the failure of Weatherford to comply with the Securities Act or
any other law, rule or regulation with respect to the distribution of the
Consideration Shares, (iv) the non-performance or the defective or negligent
performance after the Effective Date by Weatherford of any contracts
transferred to Weatherford as part of the Transaction, to the extent such
non-performance or defective or negligent performance is not caused by

                                      17

the Sellers' breach of any of their representations or warranties contained in
the Purchase and Sale Agreement, (v) the failure by Weatherford to satisfy any
of the liabilities assumed by it under the Purchase and Sale Agreement, or
(vi) a claim by any taxing authority for any taxes allocated or attributable
to any period ending before the Effective Date.

NON-COMPETITION AGREEMENT

     In the Purchase and Sale Agreement, the Sellers have agreed that, for a
period of two years following the Effective Date, neither the Sellers nor any
affiliate of the Sellers will compete, directly or indirectly, with
Weatherford or any affiliate of Weatherford in designing, manufacturing,
selling, renting or running liner hangers, packers and gas lift valves and
systems. The Sellers also have agreed on behalf of the Sellers and their
affiliates not to solicit for employment any employee of Weatherford or any
affiliate of Weatherford, including any employee of either Seller or any
Subsidiary who becomes an employee of Weatherford or any affiliate of
Weatherford.

                    COMPARATIVE RIGHTS OF THE STOCKHOLDERS
                         OF WEATHERFORD AND NODECO AS

     Upon consummation of the Transaction, Nodeco AS will be a holder of
shares of Weatherford Common Stock. To the extent the shares of Weatherford
Common Stock held by Nodeco AS are distributed to the shareholders of Nodeco
AS, in connection with a liquidation of Nodeco AS or otherwise, holders of
shares of Nodeco AS will become holders of shares of Weatherford Common Stock.
The shares of Nodeco AS are governed by Norwegian law and the Articles of
Association of Nodeco AS. The rights of holders of Weatherford Common Stock
are governed by the law of the State of Delaware, Weatherford's Restated
Certificate of Incorporation and Weatherford's Bylaws. Set forth below are the
principal differences between the shares of Nodeco AS and Weatherford Common
Stock.

SPECIAL VOTE REQUIRED FOR CERTAIN COMBINATIONS

     Section 203 of the Delaware General Corporation Law (the "DGCL")
prohibits a corporation from engaging in a "business combination" (as
hereinafter defined) with an "interested stockholder" (defined generally to
mean a person who, together with his affiliates, owns, or if the person is an
affiliate of the corporation did own within the last three years, 15% or more
of the outstanding voting stock of the corporation) for a period of three
years after the date of the transaction in which the person became an
interested stockholder, unless (i) prior to the date of the business
combination, the board of directors of the corporation approved the business
combination or the transaction in which the stockholder became an interested
stockholder, (ii) as a result of the business combination, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced or (iii) on or subsequent to
the date of the business combination, the board of directors and the holders
of at least 66 2/3% of the outstanding voting stock not owned by the
interested stockholder approve the business combination. The DGCL defines a
"business combination" generally as: (i) a merger or consolidation with the
interested stockholder or with any other corporation if the merger or
consolidation is caused by the interested stockholder, (ii) a sale or other
disposition to or with an interested stockholder of assets with an aggregate
market value greater than or equal to 10% or more of either the aggregate
market value of all assets of the corporation or the aggregate market value of
all of the outstanding stock of the corporation; (iii) with certain
exceptions, any transaction resulting in the issuance or transfer by the
corporation or any majority-owned subsidiary of any stock of the corporation
or such subsidiary to the interested stockholder; (iv) any transaction
involving the corporation or a majority-owned subsidiary that has the effect
of increasing the proportionate share of the stock of the corporation or any
such subsidiary owned by the interested stockholder; or (v) any receipt by the
interested stockholder of the benefit of any loans or other financial benefits
provided by the corporation or any majority-owned subsidiary.

     The DGCL permits a corporation to elect not to be governed by Section
203. Weatherford's Bylaws make such an election. However, Weatherford's
Restated Certificate of Incorporation and Bylaws contain provisions similar to
Section 203 that require a higher percentage of stockholders' vote to approve
a

                                      18

Business Combination (as hereinafter defined). Pursuant to these provisions,
an "Interested Stockholder" is defined generally to mean the owner of more
than 20% of the voting power of the outstanding voting stock and any affiliate
of such person. The holders of at least 80% of the voting power of the then
outstanding shares of capital stock of Weatherford entitled to vote must
approve the Business Combination. The term "Business Combination" is defined
generally to include any of the following transactions in which an Interested
Stockholder is involved: (i) a merger or consolidation, (ii) a sale or other
disposition of assets having a fair market value of $1 million or more, (iii)
an issuance or transfer of any securities having a fair market value of $1
million or more, (iv) a plan of liquidation or dissolution or (v) certain
transactions that increase the proportionate share of the outstanding shares
of any class of equity or convertible securities owned by an Interested
Stockholder or any of its affiliates. The special stockholder voting
requirement of the fair price provisions is not applicable to a Business
Combination if either (i) a majority of the Continuing Directors (as
hereinafter defined) approves the Business Combination or (ii) certain minimum
price, form of consideration and procedural requirements are satisfied.
Weatherford's Restated Certificate of Incorporation generally defines
"Continuing Director" to mean a director who either (i) was unaffiliated with
the Interested Stockholder and was a member of the Weatherford Board of
Directors prior to the time that the Interested Stockholder became an
Interested Stockholder or (ii) was designated in the appropriate manner as a
Continuing Director by the other Continuing Directors.

     Neither the Articles of Association of Nodeco AS nor Norwegian law
contains any provisions similar to that contained in Weatherford's Restated
Certificate of Incorporation regarding a special vote for certain business
combinations with "interested" stockholders.

VOTE REQUIRED FOR EXTRAORDINARY CORPORATE TRANSACTIONS

     Under the DGCL, an amendment to a corporation's certificate of
incorporation requires the affirmative vote of the holders of a majority of
the outstanding stock of the corporation entitled to vote thereon and a
majority of the outstanding stock of each class entitled to vote thereon as a
class, unless the corporation's certificate of incorporation provides for a
higher percentage. The DGCL also provides that the holders of a majority of
the outstanding stock of the corporation entitled to vote thereon may approve
an agreement of merger or consolidation or the dissolution of a corporation.
Weatherford's Restated Certificate of Incorporation provides that the
affirmative vote of the holders of at least 80% of the outstanding stock
entitled to vote generally in the election of directors is required for
amendments to Weatherford's Restated Certificate of Incorporation relating to
written consents and special meetings of stockholders, relating to the number,
election, terms, increase in the number, vacancy, removal and limitation on
liability of directors, and relating to certain mergers, consolidations or
dissolutions of Weatherford that involve an Interested Stockholder. See
"-- Special Vote Required for Certain Business Combinations". Norwegian law
provides that certain extraordinary corporate transactions, such as an
amendment to the articles of association, an increase in the share capital of
the company, a merger, a voluntary liquidation or a sale of all of the assets
of a company in preparation of a liquidation, require the affirmative vote of
two-thirds of the shares entitled to vote at any meeting of the shareholders
held for such purpose.

ELECTION AND APPOINTMENT OF DIRECTORS

     Under the DGCL, directors of a corporation shall be elected by the
stockholders of the corporation by a plurality of the votes of the shares
entitled to vote on the election of directors. In addition, Weatherford's
Bylaws permit the Board of Directors to fill any vacancy occurring in the
Board of Directors caused by death, resignation, retirement, disqualification
or removal from office of any director, or otherwise, or if any new
directorship is created by an increase in the authorized number of directors.
Norwegian law provides that the directors of a company shall be elected by the
stockholders of the company by a majority of the votes of the shares entitled
to vote at such meeting and that the board of directors of a company cannot
fill a vacancy on the board of directors.

                                      19

INDEMNIFICATION OF BOARD MEMBERS

     Weatherford's Restated Certificate of Incorporation contains a provision
that eliminates the personal monetary liability of a director to Weatherford
and its stockholders for breach of his fiduciary duty of care as a director to
the extent currently allowed under the DGCL. Weatherford also has entered into
an indemnification agreement with each of its directors. Neither Norwegian law
nor the Articles of Association of Nodeco AS contain any provisions concerning
indemnification by Nodeco AS of members of its board of directors.

REMOVAL OF DIRECTORS

     Weatherford's Restated Certificate of Incorporation and Bylaws provide
that, subject to the rights of the holders of any outstanding shares of serial
preferred stock of Weatherford, no director may be removed from office, except
for cause and upon the affirmative vote of the holders of at least 80% of the
outstanding stock entitled to vote for the election of directors. Norwegian
law provides that directors of a Norwegian company can be removed by a
majority vote of the shares entitled to vote at any meeting of the
shareholders for such purpose.

PREEMPTIVE RIGHTS

     Under Norwegian law, shareholders of a Norwegian company have preemptive
rights with respect to the issuance of additional share capital of the
company. The board of directors of a Norwegian company may propose, and the
shareholders may accept, voiding the preemptive rights with respect to any
given share issuance. Weatherford's Restated Certificate of Incorporation
specifically denies preemptive rights to the stockholders of Weatherford.

CALLING OF STOCKHOLDERS MEETINGS

     Weatherford's Bylaws provide that special meetings of the stockholders of
Weatherford may be called only by the Board of Directors pursuant to a
resolution approved by a majority of the entire Board of Directors, and only
by written notice given to the stockholders of Weatherford not less than 30
nor more than 60 days before such meeting. Norwegian law provides that
shareholder meetings may be called by the board of directors and can be
requested by a 10% shareholder, with notice to be delivered at least one week
prior to such meeting.

STOCKHOLDERS MEETING QUORUM

     Weatherford's Bylaws provide that a vote of stockholders may be taken
only at a meeting at which a quorum of stockholders representing a majority of
the stock issued and outstanding and entitled to vote thereat is present.
Norwegian law contains no quorum requirement for a shareholder meeting of a
Norwegian company.

DIRECTOR QUALIFICATION AND NUMBER

     The DGCL provides that the number of directors of a Delaware corporation
shall be fixed by, or in the manner provided in, the bylaws, unless such
number is changed by action of the majority of the directors. Weatherford's
Bylaws provide for the number of directors to be not less than six nor more
than 15. The Weatherford Board of Directors currently is set at ten directors.
The Articles of Association of Nodeco AS provide for the number of directors
to be not less than three nor more than seven as determined at a meeting of
the shareholders of Nodeco AS. The board of directors of Nodeco AS currently
is set at five directors.

                  UNAUDITED PRO FORMA FINANCIAL INFORMATION

   
     The unaudited pro forma financial statements are based upon (i) the
historical consolidated financial statements of Weatherford and Nodeco, which
are incorporated by reference or included elsewhere in this Prospectus, and
(ii) the unaudited historical combined statement of operations of the natural
gas compression businesses of Zapata Corporation ("Energy Industries") for the
period from January 1, 1995 through December 15, 1995, the date upon which
Weatherford acquired Energy Industries in a purchase business combination. The
historical consolidated financial statements of Nodeco prepared in accordance
with Norwegian GAAP together with adjustments necessary to conform with US
GAAP were utilized in preparing the Unaudited Pro Forma Financial Information
which, with respect to the Unaudited Pro Forma Balance Sheet, reflects the
December 31, 1995 exchange rate of NOK 6.3211 per United States dollar and,
with respect to the Unaudited Pro Forma Statement of Income, reflects the 1995
average exchange rate of NOK 6.3131 per United States dollar. The unaudited
pro forma financial statements were prepared assuming that the Transaction was
consummated with 750,000 shares of Weatherford Common Stock valued at $36.25
per share, cash consideration of $13,962,000 (or NOK 90,603,500), an exchange
rate of NOK 6.4893 per United States dollar and estimated transaction costs of
$250,000.
   

     The Unaudited Pro Forma Balance Sheet was prepared assuming that the
Transaction was consummated as of December 31, 1995. The Unaudited Pro Forma
Statement of Income gives effect to (i) the proposed Transaction under the
purchase method of accounting, (ii) the acquisition by Weatherford of Energy
Industries under the purchase method of accounting and (iii) certain estimated
operational and financial combination benefits of $48,400,000 per year
resulting from Weatherford's October 5, 1995 merger with Enterra Corporation
(the "Enterra Merger") and $10,000,000 per year resulting from the December
15, 1995 acquisition of Energy Industries. The Unaudited Pro Forma Statement
of Income was prepared assuming that the transactions set forth above were
consummated as of January 1, 1995. The unaudited pro forma financial
statements have been prepared based upon assumptions deemed appropriate by
Weatherford and may not be indicative of actual results.

              NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

     1.  To record the issuance of 750,000 shares of Weatherford Common Stock
(valued at $36.25 per share) and borrowings used to finance the Transaction
and to reflect the allocation of the related purchase price.

     2.  To record certain estimated consolidation cost savings and
operational efficiencies, and the related tax effect, associated with the
Enterra Merger, primarily resulting from the combination of certain service
locations and the elimination of duplicate corporate functions.

     3.  To exclude nonrecurring expenses of $59,900,000 incurred by
Weatherford in conjunction with the Enterra Merger and the related tax effect
of $12,189,000. These nonrecurring expenses primarily represent transaction
costs, severance and termination agreement costs, facility closure costs and
the reduction in recorded value of certain assets that had diminished value in
the operations of the combined company.

     4.  To record certain estimated consolidation cost savings and
operational efficiencies associated with the acquisition of Energy Industries
on December 15, 1995, primarily resulting from the combination of certain
locations and the elimination of duplicate corporate functions.

     5.  To record the amortization of additional goodwill resulting from the
allocation of the purchase price of Energy Industries.

     6.  To record additional interest expense on the debt incurred by
Weatherford on its acquisition of Energy Industries.

     7.  To record income tax expense on the Energy Industries operations and
the effect of the Energy Industries adjustments discussed in Notes 4, 5 and 6
above.

     8.  To record additional depreciation and the amortization of additional
goodwill resulting from the allocation of the purchase price of the
Transaction.

     9.  To record additional interest expense on the debt to be incurred by
Weatherford to consummate the Transaction.

     10.  To record the income tax effect of the Nodeco adjustments discussed
in Notes 8 and 9 above.

                 NODECO MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   
BUSINESS DESCRIPTION

     Nodeco designs, manufactures, sells and rents oil and gas well completion
products primarily consisting of liner hanger equipment and related services, as
well as packers used in completions with electric submersible pumps.
Historically, Nodeco has focused its marketing efforts on the North Sea market,
and Nodeco only recently has increased its international sales efforts. Nodeco
actively provides liner hanger equipment and services in all sectors of the
North Sea as well as certain other parts of the world. Until recently,
substantially all of Nodeco's pump packer sales have been to operators in the
United Kingdom sector of the North Sea, since no electric submersible pump
completions had been made in the Norwegian sector. Nodeco has made sales of pump
packers to certain Norwegian producers.
   

     Aarbakke, a wholly-owned subsidiary of Nodeco AS, is a manufacturing unit
that also provides precision machining services to third parties in Norway and
other countries. Approximately half of Aarbakke's production capacity is used
for third-party manufacturing, of which 80% relates to oil industry activities.

     SubTech, a 51% owned subsidiary of Nodeco AS, provides consulting services
related to production and reservoir monitoring activities, as well as design,
fabrication and installation of systems for such activities, primarily for
customers in Norway.

RESULTS OF OPERATIONS

   
                                           YEAR ENDED DECEMBER 31,
                                       -------------------------------

                                       =========  =========  =========


     PRODUCT REVENUES. Product revenues increased 36% to NOK 118.6 million in
1995 compared with NOK 87.0 million in 1994. The increase was primarily
attributable to increased volume of liner hanger sales in North and West Africa
(relatively new markets for Nodeco), increased pump packer sales in the United
Kingdom due to customer acceptance of the Resettable Pump Packer and increased
sales to third parties in contract manufacturing. Product revenues increased 4%
to NOK 87.0 million in 1994 compared with NOK 83.6 million in 1993, primarily as
a result of increased drilling activity in both the Norwegian and United Kingdom
sectors of the North Sea and increased sales of downhole temperature and
pressure gauges, which increase was partially offset by declines in liner hanger
sales in markets outside of the North Sea.

     RENTAL REVENUES. Rental revenues increased 27% to NOK 30.5 million in 1995
compared with NOK 24.0 million in 1994, reflecting increased liner hanger
equipment rental activity in the North Sea. Rental revenues increased 20% to NOK
24.0 million in 1994 compared with NOK 20.1 million in 1993, primarily as a
result of increased rental activity of liner hanger and pump packer equipment.

     SERVICE REVENUES AND OTHER CHARGES. Service revenues and other charges
increased 5% to NOK 24.8 million in 1995 compared with NOK 23.6 million in 1994,
primarily due to increased North Sea drilling activity. Service revenues and
other charges increased 25% to NOK 23.6 million in 1994 compared with NOK 18.8
million in 1993, primarily as a result of increased repair services related to
temperature and pressure gauges.


     OPERATING COSTS. The costs attributable to raw materials, payments to
subcontractors and payroll increased approximately 30% in 1995 compared with
1994, primarily due to an increase in operating revenues, overall higher levels
of drilling activity in the North Sea and the need for additional employees to

                                      27

meet increased demand. Operating costs changed relatively little in 1994
compared with 1993. Though Nodeco achieved cost savings in 1994 due to the
negotiation of more favorable purchase agreements, the costs associated with
slightly higher levels of drilling activity in the North Sea and the need for
additional employees generally offset such savings.

     EXTRAORDINARY GAIN (LOSS). In 1995, Nodeco recognized a gain of NOK 2.3
million as a result of the sale of Bryne Petropark AS, a subsidiary which owns
real estate including the workshop and offices currently used by Nodeco AS. Such
gain was partially offset by an extraordinary loss of NOK 0.9 million,
representing costs incurred related to the termination of operations of Nodecore
AS, a subsidiary engaged in the coring business.

     In 1993, Nodeco recognized an extraordinary loss of NOK 5.8 million related
to the termination of the operations of a subsidiary, Pressure Test Laboratories
AS, and the termination of robotic systems operations, which was partially
offset by a NOK 1.0 million gain on the forgiveness of a subsidiary's debt
related to a bank loan.

LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 1995, Nodeco had working capital of NOK 25.8 million and a
current ratio of 1.46 to 1.0. Working capital increased 68% in 1995 compared
with 1994 due to increases in accounts receivable and inventory as a direct
result of the increased demand for Nodeco's products and services.

     Nodeco had an aggregate of NOK 28.3 million in outstanding debt as of
December 31, 1995. Nodeco's outstanding debt is comprised of (i) secured
borrowings totaling NOK 28.1 million that bear interest at rates ranging from 6%
to 12% per annum and have maturity dates from 1996 through 2014 and (ii) one
subordinated loan of NOK 0.2 million that bears interest at 10% per annum and
matures in 1997. In addition, Nodeco had NOK 10.2 million in bank overdrafts
outstanding at December 31, 1995 that bear interest at rates ranging from 7.5%
to 9.25%. Such overdrafts were used to finance working capital requirements.
Sources of liquidity to finance commitments, working capital requirements and
future capital expenditures include cash of NOK 6.6 million and unused overdraft
facilities of approximately NOK 7.7 million as of December 31, 1995. Management
of Nodeco believes that the combination of working capital, the unused portion
of existing credit facilities and cash flows from operations provide Nodeco with
sufficient capital resources and liquidity to manage its day-to-day operations
and future investment in fixed assets at current levels of activity.

     Net cash flows from operating activities decreased 58% to NOK 10.0 million
in 1995 compared with NOK 23.8 million in 1994, primarily due to increased
investment in working capital arising from an increase in product and rental
activities. Net cash flows from operating activities improved from a net outflow
of NOK 3.0 million in 1993 to a net inflow of NOK 23.8 million in 1994,
primarily reflecting improved net income of Nodeco and changes in working
capital.

     Cash flows from investing activities generally are comprised of investment
in, and disposal of, fixed assets. Investment in fixed assets increased 99% to
NOK 20.6 million in 1995 compared with NOK 10.4 million in 1994, primarily due
to the purchase of new manufacturing equipment and additions to one of Nodeco's
plants. The increase reflects Nodeco's need for additional capacity to
accommodate the growth in sales volume over the last several years. The disposal
of fixed assets in 1995 of NOK 25.2 million was primarily related to the sale of
Bryne Petropark AS. Investment in fixed assets of NOK 10.4 million in 1994 was
relatively unchanged compared with NOK 10.5 million in 1993.

     Net cash flows from financing activities in 1995 were affected by a
reduction of debt totaling NOK 31.3 million primarily as a result of the sale of
Bryne Petropark AS, partially offset by new borrowings totaling NOK 14.8 million
to finance working capital needs and investments in fixed assets. Net cash flows
from financing activities in 1994 were the result of a repayment of debt related
to payment of periodic installments of existing obligations. Nodeco also
declared an NOK 8 per share dividend in 1994. New debt in 1993 of NOK 18.5
million primarily consisted of drawdowns on Nodeco's overdraft facility to
finance working capital needs and investments in fixed assets.

CURRENCY FLUCTUATIONS

     Nodeco conducts a portion of its business in currencies other than NOK,
including the United Kingdom pound sterling and the United States dollar.
Although most of the revenues of Nodeco's foreign operations are denominated in
the local currency, the effects of foreign currency fluctuations are largely
mitigated because expenses of such foreign operations also generally are
denominated in the same currency.

     Nodeco occasionally enters into forward exchange contracts only as a hedge
against certain existing economic exposures and not for speculative trading
purposes. These contracts reduce exposure to currency movements affecting
existing assets and liabilities denominated in foreign currencies, with such
exposure resulting primarily from trade receivables and payables and
intercompany and external long-term loans. The future value of these contracts
and the related currency positions are subject to offsetting market risk
resulting from foreign currency exchange rate volatility. Settlement of forward
exchange rate contracts resulted in net cash outflows of approximately NOK
350,000 during 1993 and net cash inflows of approximately NOK 500,000 and NOK
250,000 during 1995 and 1994, respectively.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of Nodeco AS:

     We have audited the accompanying consolidated balance sheet of Nodeco AS
and its subsidiaries as of December 31, 1995 and 1994 and the related
consolidated statements of income, of cash flows and of changes in shareholders'
equity for the years then ended, all expressed in Norwegian Kroner. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements audited by us present
fairly, in all material respects, the financial position of Nodeco AS and its
subsidiaries at December 31, 1995 and 1994, and the results of their operations
and their cash flows for the years then ended in conformity with accounting
principles generally accepted in Norway.

     Accounting principles generally accepted in Norway vary in certain
important respects from accounting principles generally accepted in the United
States. The application of the latter would have affected the determination of
consolidated shareholders' equity expressed in Norwegian Kroner as of December
31, 1995 and 1994 and the determination of consolidated net income, also
expressed in Norwegian Kroner, for the years then ended to the extent summarized
in Note 11 to the consolidated financial statements.

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1993 UNAUDITED)

NOTE 1  ACCOUNTING POLICIES

GENERAL

     The consolidated financial statements of Nodeco AS, a Norwegian
corporation, and its subsidiaries (the "Company" or "Nodeco AS") have been
prepared according to generally accepted accounting principles in Norway
(Norwegian GAAP) and are presented in Norwegian kroner (NOK).

     Norwegian GAAP differs in certain significant respects from accounting
principles generally accepted in the United States (US GAAP). The significant
differences and the approximate related effects on the consolidated financial
statements as of December 31, 1995 and for the year then ended are set forth in
Note 11. The consolidated financial statements also include certain
reclassifications and disclosures in order to conform more closely to the form
and content required by the Securities and Exchange Commission of the United
States.

PRINCIPLES OF CONSOLIDATION

  SUBSIDIARIES

     The consolidated financial statements include Nodeco AS and each subsidiary
in which the Company owns or controls, either directly or indirectly, more than
50% of the equity capital. Intercompany transactions and balances have been
eliminated.

     Businesses acquired generally are consolidated in accordance with the
purchase method. The purchase price for a subsidiary is allocated to
identifiable assets and liabilities based upon their estimated fair market
value, with any remaining amounts capitalized as goodwill.

     Results of subsidiaries acquired or sold during the year are included in
the consolidated income statement from the date of acquisition or up to the date
of sale, respectively.

     A business combination, accomplished solely by the exchange of equity,
which represents a uniting of ownership with another enterprise rather than an
acquisition, is accounted for in accordance with merger accounting. The recorded
assets and liabilities of the other enterprise are carried forward to the
combined accounts at their recorded amounts. The acquisition of Aarbakke AS
during 1992 was accounted for in accordance with this method.

  TRANSLATION OF FOREIGN SUBSIDIARIES' FINANCIAL STATEMENTS

     The functional currency of each foreign subsidiary is the local currency.
Revenues, expenses, gains and losses of foreign subsidiaries are translated into
Norwegian kroner using the average exchange rate for the period. Assets and
liabilities of foreign subsidiaries are translated into Norwegian kroner at the
exchange rate in effect at the balance sheet date. Translation differences
caused by fluctuations in exchange rates are charged or credited to
shareholders' equity.

REVENUE RECOGNITION PRINCIPLES

   
     Revenue from sale of finished goods is recognized upon delivery. Revenue
from rental of equipment is recognized over the rental period. Service
revenues are recognized as the service is provided.
   

     Provision is made for estimated bad debts. The allowance for bad debts is
NOK 155,000 at December 31, 1995 and 1994.

OTHER PRINCIPLES

  INVENTORIES

     Inventories are recorded at full cost under the first in first out (FIFO)
method. Provision is made for obsolete and slow moving inventory.

                                      F-7

                                   NODECO AS
   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1993 UNAUDITED) -- (CONTINUED)

  CURRENT ASSETS AND CURRENT LIABILITIES

     Assets and liabilities which relate to the production cycle and accounts
receivable collectible within one year of the balance sheet date are classified
as current.

  FIXED ASSETS

     Fixed assets are stated at cost less accumulated depreciation. Depreciation
is provided principally by the straight line method over the estimated useful
lives of the various classes of assets. The following depreciation rates are
used:

Machinery, fixtures and vehicles.....  12-30%
Rental equipment.....................  20%
Buildings............................  3-5%

  FOREIGN CURRENCY TRANSACTIONS

     Current assets and liabilities denominated in foreign currencies are
remeasured using the exchange rate as of each balance sheet date. Unrealized
gains and losses on current assets and liabilities are recognized.

     Non-current liabilities denominated in foreign currencies are remeasured
using the higher of the exchange rate on the transaction date or on the balance
sheet date.

     Net unrealized foreign currency transaction losses are included in
financial expense. Net unrealized foreign currency transaction gains on
non-current assets and non-current liabilities are not recognized.

     Foreign currency gains and losses on forward exchange contracts that are of
a hedge nature are recognized as a component of the transaction being hedged.

  LEASES

     Leases of equipment are accounted for as operating leases, irrespective of
the terms of the leases. Rentals under these leases are expensed over the lease
term.

  PENSIONS

     Nodeco AS and its Norwegian subsidiaries sponsor pension plans for
substantially all of their employees. In accordance with Norwegian law, such
plans are funded through contributions to insurance companies that assume all
the liabilities for benefit payments. Employees earn benefits in accordance with
a defined benefits formula and the companies are charged yearly premiums for the
liabilities assumed by the insurance companies. The annual premiums to fund the
plans are expensed.

     Employees of the Company's subsidiaries operating outside of Norway
participate in pension plans which are considered to be defined contribution
plans. Contributions to these plans are expensed.

  CONTINGENCIES

     An estimated loss from a contingency is charged to income if it is probable
that an asset has been impaired or a liability has been incurred at the date of
the financial statements and the amount of the loss can be reasonably estimated.
Disclosure is made for loss contingencies not meeting both those conditions if
there is a reasonable possibility that a material loss may be incurred.

     No accruals are made for contingent gains.

  INCOME TAXES

     Deferred taxes are computed in accordance with the liability method, which
bases the estimated amount of future taxes to be refunded or payable on the
temporary differences between financial and tax bases of assets and liabilities
and on the prevailing tax laws as of the balance sheet date. The impact of any

tax rate or rule changes on deferred tax liabilities is recognized in the year
such changes are legally enacted. Deferred tax assets are only recognized to the
extent the Company has deferred tax liabilities.

  EXTRAORDINARY ITEMS

     Extraordinary items reflect transactions which are irregular and related to
transactions or decisions outside the normal course of business, unusual in
nature and not expected to occur often or regularly.

NOTE 10  SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES
         FOLLOWED BY THE COMPANY AND U.S. GENERALLY ACCEPTED ACCOUNTING
         PRINCIPLES

     The accompanying consolidated financial statements have been prepared in
accordance with Norwegian GAAP, which differs in certain respects from US GAAP.
These differences are reflected in the reconciliation provided in Note 11 and
principally relate to the following items:

BUSINESS COMBINATIONS

     As described in Note 1, under Norwegian GAAP, the acquisition of Aarbakke
AS in 1992 was accounted for as a merger. Merger accounting is similar to the
pooling-of-interests method of accounting for acquisitions under US GAAP. The
requirements for merger accounting are, however, less restrictive than those for
pooling-of-interests. Under US GAAP, the acquisition of Aarbakke AS is accounted
for using the purchase method of accounting and the assets and liabilities of
Aarbakke AS are recorded at their fair value as of the date of the acquisition.
Also, under US GAAP the results of operations of Aarbakke AS are only included
in the consolidated financial statements of the Company from the date of the
acquisition. Goodwill recognized in accordance with US GAAP arising on the
acquisition of Aarbakke AS is amortized over 10 years.

LEASES

     Under the terms of several leases for production equipment, substantially
all the risks and rewards of ownership of the leased assets are transferred to
the Company. Such leases have been accounted for as operational leases in the
Norwegian GAAP financial statements. Under US GAAP these leases are considered
to be capital leases whereby they are recorded as the acquisition of assets and
liabilities incurred.

DEFERRED TAX ASSET

     Norwegian GAAP prohibits recognition of a net deferred tax asset. Under US
GAAP, deferred tax assets are recognized to the extent realization is considered
probable.

PENSIONS

     In the Norwegian GAAP financial statements, pension cost is charged to
expense based upon premiums paid to an insurance company for funded plans.

     Under US GAAP, pension cost is actuarially determined in accordance with
Statement of Financial Accounting Standards (SFAS) No. 87, "Employers"
Accounting for Pensions'.

EMPLOYEE STOCK OPTIONS

     For purposes of Norwegian GAAP, Nodeco does not recognize any expense
related to employee stock options. Under US GAAP, in accordance with Accounting
Principles Board Statement No. 25, Nodeco measures compensation expense as the
difference between the option price and the fair value of the underlying stock
at the date the option is granted and accrues the expense
over the vesting period.

EXTRAORDINARY GAINS AND LOSSES

     Under Norwegian GAAP, the criteria for classification of gains or losses as
extraordinary are less restrictive than the criteria applied under US GAAP.
Accordingly, an item which is considered to be extraordinary under Norwegian
GAAP may not be considered extraordinary under US GAAP. Under Norwegian GAAP,
extraordinary gains and losses are presented before income taxes. Under US GAAP,
extraordinary gains and losses are presented net of related income taxes. The
differences between Norwegian GAAP and US GAAP in the determination and
presentation of extraordinary items does not result in differences in net income
or shareholders' equity.

                                  NODECO AS
  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1993 UNAUDITED) -- (CONTINUED)

FOREIGN CURRENCY TRANSACTIONS

     As described in Note 1, under Norwegian GAAP the Company follows a policy
of remeasuring non-current liabilities denominated in a foreign currency using
the higher of the exchange rate on the transaction date or on the balance sheet
date. Net unrealized gains on non-current assets and liabilities denominated in
foreign currency calculated on a portfolio basis are not recognized in income.
Under US GAAP, all assets and liabilities denominated in a foreign currency are
remeasured using the year-end exchange rate, and both unrealized gains and
unrealized losses are recognized currently in income.

DIVIDENDS

     Under Norwegian law, dividends are payable out of annual earnings. The
amount of dividends is subject to approval by the Company's shareholders at the
annual general meeting, following the fiscal year to which the dividends relate.
Under Norwegian GAAP, dividends are accrued in the year of the earnings to which
they relate. Under US GAAP, dividends are recorded when declared. Accordingly,
under US GAAP, dividends are recorded in the year following the year in which
they are recorded under Norwegian GAAP.

CLASSIFICATION OF CASH FLOWS

     For Norwegian GAAP purposes, Nodeco has presented the reduction in
consolidated assets and liabilities which results from the 1995 sale of its
subsidiary, Bryne Petropark AS, as cash flows related to operating, investing
and financing activities, depending upon the classification of the related
balance sheet items of such subsidiary. Under US GAAP, the total net proceeds
from the sale of such subsidiary are presented as one line item within cash
flows from investing activities. For US GAAP purposes, cash flows from
operating, investing and financing activities aggregate a positive NOK
10,783,000, a negative NOK 16,210,000 and a positive NOK 4,662,000,
respectively, for the year ended December 31, 1995.

8  SELLERS' WARRANTIES AND INDEMNIFICATION

     8.1  The Sellers warrant to the Purchaser that at the date hereof:

          a)   Each of the statements in the Schedules (except Schedules 9 and
               13) is true and accurate and the Schedules do not omit any
               material fact;

          b)   the Sellers have, to the best of their knowledge, provided all
               information relating to the Sellers and the Subsidiaries and
               their respective affairs which would be material to the Purchaser
               for the valuation of the Business and the Assets;

     8.2 If any one or more of the warranties in Clause 8.1 or in the Schedules
are untrue, inaccurate, misleading or breached at the Effective Date, the Cash
Consideration to be paid at the Effective Date shall be reduced by the
Deficiency Amount (as such term is defined below); provided that if the
Purchaser provides written notice to the Sellers, or the Sellers provide written
notice to the Purchaser, that the aggregate Deficiency Amount is in excess of
NOK 44,000,000, the Parties shall use their reasonable best efforts to reach an
agreement with respect to the sale of the Business to the Purchaser on mutually
acceptable terms; provided further that if the Parties are unable to reach such
an agreement within

                                      7

10 Business Days following delivery of any such notice, any Party may terminate
this Agreement by delivery to the other Parties of a written notice to such
effect within 5 Business Days after such 10 Business Day time limit has elapsed.
The "Deficiency Amount" shall equal, as applicable, the value at the Effective
Date of the specific Assets (or portions thereof) and the specific Assumed
Liabilities (or portions thereof) that resulted in the warranties in Clause 8.1
and the Schedules being untrue, inaccurate, misleading or breached; provided
that "Deficiency Amount" shall not include any indirect or consequential loss or
damage, including, but not limited to, loss of goodwill or similarly related
indirect losses or damages. If any one or more of the warranties in Clause 8.1
and the Schedules are untrue, inaccurate, misleading or breached at the
Effective Date, but such untrue, inaccurate, misleading or breached warranty is
not discovered until after the Effective Date, the Sellers shall promptly
reimburse to the Purchaser an amount equal to the Deficiency Amount, plus
interest on such amount at the rate of 8% per annum from the Effective Date
until the date of repayment.

     To the extent that any third party presents a claim against the Purchaser
or any Subsidiary related to events that occurred prior to the Effective Date
and such claim has not resulted in the reduction of the Cash Consideration at
the Effective Date or a reimbursement by the Sellers to the Purchaser as
described in the immediately preceding paragraph, the Sellers shall indemnify
and hold harmless the Purchaser and the Subsidiaries, as the case may be,
against all losses, claims, damages, liabilities, costs or other expenses
("Losses") relating to such third party claims that the Purchaser or any
Subsidiary, as the case may be, may reasonably incur or become subject to,
insofar as such Losses (or actions in respect thereof) arise out of, are based
upon or are in connection with any untrue, inaccurate, misleading or breached
warranty made by the Sellers under Clause 8.1 or the Schedules, by reimbursing
the Purchaser an amount equal to such Losses, provided that Losses shall not
include any indirect or consequential loss or damage, including, but not limited
to, loss of goodwill or similarly related indirect losses or damages.

     The Sellers shall without undue delay be notified of any third party claim
for which indemnification will be sought by the Purchaser or any Subsidiary
under this Agreement and the Sellers will have the right to assume control and
direct defence thereof using counsel selected by the Sellers provided that such
counsel shall not have a conflict with the Purchaser in connection with such
legal representation. The Parties shall cooperate with each other and provide
each other with access to relevant books and records in their possession. No
such third party claim shall be settled without the prior written consent of the
Sellers. If a firm written offer is made to settle any such third party claim
and the Sellers propose to accept such settlement, and the Purchaser refuses to
consent to such settlement, then the Sellers shall be excused from and the
Purchaser shall be solely responsible for all further defence of such third
party claim. The maximum liability for the Sellers relating to such third party
claim shall be the amount of the proposed settlement.

     For a period of three years from the Effective Date, the Sellers will
indemnify and hold harmless the Purchaser and the Subsidiaries as the case may
be against any and all Losses (including deficiencies, taxes, interest and
penalties) they may reasonably incur or become subject to, insofar as such
Losses arise out of, are based upon or are in connection with a claim by any
taxing authority for any taxes allocated or attributable to any period ending on
or before the Accounts Date, which has not been included in the Accounts;
provided however, that this indemnity shall only apply if the Purchaser and the
Subsidiaries have given the Sellers the right to take all action to refute such
claim by such taxing authority.

     The Sellers shall promptly reimburse each indemnified party for all legal
or other expenses reasonably incurred by it in connection with investigating or
defending any Losses, including any amounts paid in settlement of any litigation
commenced or threatened if such settlement is effected with a prior written
consent of the Sellers.

     The liability of the Sellers under this Clause 8.2 (other than liability
under the fourth paragraph hereof) shall not arise unless the aggregate amount
of all claims (other than claims under the fourth paragraph hereof) exceeds NOK
4,000,000, in which event the liability of the Sellers shall be limited to the
amount in excess of NOK 4,000,000. The liability of the Sellers under the fourth
paragraph of this Clause 8.2 shall not arise unless the aggregate amount of all
claims under the fourth paragraph of this Clause 8.2 exceeds NOK

                                      8

1,000,000, in which event the liability of the Sellers shall be limited to the
amount in excess of NOK 1,000,000.

     8.3 The liabilities of the Sellers in respect of the warranties (except
those referred to in Clause 8.2, fourth paragraph above) shall terminate one
year after the Effective Date unless written notice of the matter complained of
(giving such details as shall be reasonably practicable) shall have been given
by the Purchaser to the Sellers prior to the expiry of such one year period.

     8.4 The Sellers' liability under this clause shall under no circumstances
exceed in aggregate NOK 75 million. No claim shall be made in respect of
indirect or consequential loss or damage.

     8.5 The Sellers shall not be liable for any claim under this Clause 8, when
the claim or the issues and circumstances giving rise to the claim is disclosed
to the Purchaser in the Accounts, in the Disclosure Letter or during the
Purchaser's due diligence review of the Sellers and its Subsidiaries, provided,
however, the Sellers can prove beyond reasonable doubt that such disclosure has
taken place.

     8.6 The Sellers' liability under this clause shall be guaranteed by the
Shareholders in a joint but not several manner and in the form set forth in
Schedule 13 and none of the Shareholders shall be responsible towards the
Purchaser for more than its percentage of any claim presented which is equal to
its guarantee percentage as set out in Schedule 7.

     8.7 The warranties in Clause 8.1 and the Schedules, and the remedies
available to the Purchaser in case of breach of warranties set out in this
Agreement, are exhaustive and the Sellers shall have no liability to the
Purchaser other than as set out in this Agreement.

9  PURCHASER'S WARRANTIES AND INDEMNIFICATION

     9.1 The Purchaser warrants to the Sellers that at the date hereof each of
the statements in Schedule 9 is true and accurate and Schedule 9 does not omit
any material fact.

     9.2 Purchaser shall indemnify and hold harmless each Seller against all
Losses it may reasonably incur or become subject to under the Securities Act,
the Securities Exchange Act of 1934, as amended, or otherwise, insofar as such
Losses (or actions in respect thereof) arise out of, are based upon or are in
connection with (1) any untrue, inaccurate, misleading or breached warranty made
by the Purchaser under Clause 9.1 or Schedule 9; (2) any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement, the prospectus included therein, or any amendments, supplements or
exhibits thereto or material incorporated by reference therein, or the omission
or alleged omission to state in such documents a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; provided that the
Purchaser will not be liable under this clause (2) to the extent Losses are
based on an untrue statement or omission or alleged untrue statement or omission
made in reliance upon and in conformity with information relating to either
Seller or any Subsidiary furnished in writing by either Seller or any Subsidiary
to the Purchaser expressly for inclusion therein; or (3) the failure of the
Purchaser to comply with the Securities Act or any other law, rule or regulation
with respect to the distribution of the Consideration Shares to the Sellers.

     The Purchaser shall without undue delay be notified of any third party
claim for which indemnification will be sought by either Seller under this
Agreement and the Purchaser will have the right to assume control and direct
defence thereof using counsel selected by the Purchaser provided that such
counsel shall not have a conflict with the Sellers in connection with such legal
representation. The Parties shall cooperate with each other and provide each
other with access to relevant books and records in their possession. No such
third party claim shall be settled without a prior written approval of the
Purchaser. If a firm written offer is made to settle any such third party claim
and the Purchaser proposes to accept such settlement, and the Sellers refuse to
consent to such settlement, then the Purchaser shall be excused from and the
Sellers shall be solely responsible for all further defence of such third party
claim. The maximum liability for the Purchaser relating to such third party
claim shall be the amount of the proposed settlement.

     9.3 Purchaser shall promptly reimburse each indemnified party for all legal
or other expenses reasonably incurred by it in connection with investigating or
defending any Losses, including any amounts

                                      9

paid in settlement of any litigation commenced or threatened if such settlement
is effected with the prior written consent of the Purchaser.

10  THE REGISTRATION STATEMENT; SALE OF CONSIDERATION SHARES

     10.1 The Purchaser shall prepare and file with the SEC as soon as is
reasonably practicable after the date hereof the Registration Statement which
provides for the registration under the Securities Act of the Consideration
Shares to be issued to the Sellers pursuant hereto. The Purchaser shall use its
reasonable best efforts to (a) cause the Registration Statement to become
effective as promptly as practicable, (b) remove any stop order that may be
issued by the SEC with respect thereto, and (c) take all or any action necessary
or required under applicable federal or state securities laws in connection with
the issuance of the Consideration Shares to the Sellers pursuant hereto. The
Purchaser shall immediately notify the Sellers when the SEC has requested any
additional information regarding the Registration Statement, declared the
Registration Statement effective or issued or removed any stop order with
respect thereto. The Purchaser shall use its best efforts to cause the
Consideration Shares to be listed on the New York Stock Exchange.

     10.2 Sellers agree to use their reasonable best efforts to sell any
Consideration Shares in an orderly manner and to provide Purchaser with prior
notice of its intention to sell such stock.

11  THE CONTRACTS

     11.1 The Purchaser shall in respect of the period after the Effective Date
use its reasonable best efforts to meet its obligations under the Contracts.
Insofar as any consents or licences to the transfer or assignment of the benefit
and burden of the Contracts have not been obtained on the Effective Date, or if
such benefit or burden cannot effectively be so transferred or assigned to the
Purchaser except with the consent of or by an agreement with the other party or
parties thereto, then:

        a)  the Sellers shall use their reasonable best efforts to obtain the
            consent of such other party or parties to the Contracts being
            novated or assigned in terms reasonably acceptable to the
            Purchaser; and

        b)  unless and until all of the Contracts shall have been so novated or
            assigned, the Sellers shall provide to the Purchaser from the
            Effective Date the benefit and burden of the Contracts as if the
            same had been effectively novated or assigned to the Purchaser.

     The Sellers do not warrant that the Contracts are assignable or
transferable and shall not be liable or responsible in the event any of the
Contracts are cancelled or terminated due to the Purchaser's acquisition of the
Business.

     11.2 The Purchaser shall indemnify and hold harmless the Sellers against
any and all Losses they may reasonably incur or become subject to, insofar as
such Losses arise out of, are based upon or are in connection with the
non-performance or the defective or negligent performance after the Effective
Date by the Purchaser of any Contracts. The indemnification hereunder shall,
however, not apply if the Purchaser's non-performance or the defective or
negligent performance is caused by the Sellers by any breach of representations
or warranties set out in this Agreement or the schedules hereto.

     11.3 After the Effective Date the Sellers will assist the Purchaser in
notifying all existing customers of the Business in writing (in such form and at
such times as the Purchaser may reasonably require) of the sale of the Business
to the Purchaser and the arrangements being made in respect thereof and the
Sellers will use their reasonable best efforts to obtain the written consent of
such customers to such arrangements.

12  INDEMNITY BY THE PURCHASER

     In the event the Sellers receive any invoice or in the event a claim is
presented to the Sellers in any other way after the Effective Date and such
claim relates to the Assumed Liabilities, the Sellers shall without undue delay
send the invoice or written documents relating to the claim to the Purchaser and
the Purchaser shall pay the claim directly to the third party on the due date.

                                      10

     The Purchaser shall indemnify and hold harmless the Sellers against all
Losses they may reasonably incur or become subject to, insofar as such Losses
arise out of, are based upon or are in connection with any of the Assumed
Liabilities under this Agreement. The Purchaser shall furthermore indemnify and
hold harmless the Sellers against all Losses (including deficiencies, taxes,
interest and penalties) they may reasonably incur or become subject to, insofar
as such Losses arise out of, are based upon or are in connection with a claim by
any taxing authority for any taxes allocated or attributable to any period
ending on or before the Effective Date; provided, however, that this indemnity
shall only apply if the Sellers have given the Purchaser the right to take all
action to refute such claim by such taxing authority.

     The indemnification hereunder shall, however, not apply if the Loss is
caused by the Sellers by any breach of representations or warranties set out in
this Agreement or the schedules hereto.

13  BOOKS AND RECORDS

     The Sellers shall on the Effective Date (insofar as the Sellers are not
required to retain the same under Norwegian law or otherwise) deliver to the
Purchaser all of the books, records, files, papers and other documents of the

Sellers shall deliver to the Purchaser the original executed copies of the
Contracts.

     The Purchaser will for a period of ten years keep safely in Norway all such
books, records, files, papers and other documents related to the Business as the
Sellers shall transfer or cause to be transferred to the Purchaser and shall
afford the Sellers reasonable access thereto, during reasonable business hours
after notice, for as long as shall be necessary to enable the Sellers to deal
with its taxation and other liabilities in respect of the period up to the
Effective Date and will permit the Sellers and its servants, agents and
professional advisers upon reasonable notice to make copies at the Sellers'

partnership, corporation or entity that controls or is controlled by or under
common control with the Purchaser ("Purchaser Affiliate") in designing,
manufacturing, selling, renting or running liner hangers, packers and gas lift
valves and systems. Furthermore, no Seller or Seller Affiliate will solicit for

a Purchaser Affiliate.

          c)   if sent by telefax, at the expiration of 2 hours after the time
               of receipt of the correct answerback or telefax confirmation, if
               such answerback or confirmation is received before 3.00 p.m. or
               any Business Day, and in any other case at 10.00 a.m. on the next

prove that delivery was made or that the envelope containing the notice or
document was properly addressed and posted as registered mail or that the
telefax message was properly addressed and the correct answerback or telefax
confirmation was received as the case may be.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Weatherford's Restated Certificate of Incorporation contains a provision
that eliminates the personal monetary liability of a director to Weatherford and
its stockholders for breach of his fiduciary duty of care as a director to the
extent currently allowed under the Delaware General Corporation Law (the
"DGCL"). If a director were to breach the duty of care in performing his duties
as a director, neither Weatherford nor its stockholders could recover monetary
damages from the director, and the only course of action available to
Weatherford's stockholders would be equitable remedies, such as an action to
enjoin or rescind a transaction involving a breach of the fiduciary duty of
care. To the extent certain claims against directors are limited to equitable
remedies, this provision of Weatherford's Restated Certificate of Incorporation
may reduce the likelihood of derivative litigation and may discourage
stockholders or management from initiating litigation against directors for
breach of their duty of care. Additionally, equitable remedies may not be
effective in many situations. If a stockholder's only remedy is to enjoin the
completion of the Board of Directors' action, this remedy would be ineffective
if the stockholder does not become aware of a transaction or event until after
it has been completed. In such a situation, it is possible that the stockholders
and Weatherford would have no effective remedy against the directors. The
directors do not have liability for monetary damages for grossly negligent
business decisions (in violation of their duty of care), including decisions
made in connection with attempts to acquire Weatherford. Liability for monetary
damages remains for (i) any breach of the duty of loyalty to Weatherford or its
stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) payment of an
improper dividend or improper repurchase of Weatherford's stock under Section
174 of the DGCL or (iv) any transaction from which the director derived an
improper personal benefit. Weatherford's Restated Certificate of Incorporation
further provides that in the event the DGCL is amended to allow the further
elimination or limitation of the liability of directors, then the liability of
Weatherford's directors shall be limited to the fullest extent permitted by the
amended DGCL.

     The DGCL permits a corporation to indemnify certain persons, including
officers and directors, who are (or are threatened to be made) parties to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of their being officers or directors of the
corporation. The indemnity may include expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by an indemnified officer or director, provided he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the corporation's best
interests and, in the case of criminal proceedings, provided he had no
reasonable cause to believe that his conduct was unlawful. The Bylaws of
Weatherford provide indemnification to the fullest extent allowed pursuant to
the foregoing provisions of the DGCL.

     The DGCL further permits a corporation to indemnify certain persons,
including officers and directors, who are (or are threatened to be made) parties
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of their being officers
or directors of the corporation. The indemnity may include expenses (including
attorneys' fees) actually and reasonably incurred by the indemnified officer or
director, provided he acted in good faith and in a manner he reasonably believed
to be in, or not opposed to, the corporation's best interests. However, no such
person will be indemnified as to matters for which he is found to be liable for
negligence or misconduct in the performance of his duty to the corporation
unless, and only to the extent that, indemnification is ordered by a court. The
Bylaws of Weatherford provide indemnification to the fullest extent allowed
pursuant to the foregoing provisions of the DGCL.

     Weatherford also has entered into an indemnification agreement with each of
its directors and certain of its officers. Each such indemnification agreement
provides for indemnification to the fullest extent permitted by the DGCL and for
the advancement of expenses, including attorneys' fees and other costs,

                                     II-1

expenses and obligations, paid or incurred in connection with investigating,
defending, being a witness in or participating in (including on appeal) any
threatened, pending or completed action, suit or proceeding related to the fact
that such director or officer was serving for or at the request of Weatherford.
To the extent that the Board of Directors or the stockholders of Weatherford may
in the future wish to limit or repeal the ability of Weatherford to indemnify or
advance expenses to officers and directors, such repeal or limitation may not be
effective as to officers and directors who are parties to an indemnification
agreement, since their rights to full protection are contractually assured by
the indemnification agreement.

     Delaware corporations also are authorized to obtain insurance to protect
officers and directors from certain liabilities, including liabilities against
which the corporation cannot indemnify its directors and officers. Weatherford
currently has in effect a directors' and officers' liability insurance policy
providing aggregate coverage in the amount of $10,000,000.

     All of the foregoing indemnification provisions include statements that
such provisions are not to be deemed exclusive of any other right to indemnity
to which a director or officer may be entitled under any bylaw, agreement, vote
of stockholders or disinterested directors or otherwise.

ITEM 22.  UNDERTAKINGS

     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 the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, 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 foregoing provisions, 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. In the event that 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.

     The undersigned registrant hereby undertakes that:

          (1) Prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other Items
     of the applicable form; and

          (2) Every prospectus (i) that is filed pursuant to paragraph (1)
     immediately preceding, or (ii) that purports to meet the requirements of
     section 10(a)(3) of the Securities Act, and is used in connection with an
     offering of securities subject to Rule 415, will be filed as a part of an
     amendment to the registration statement and will not be used until such
     amendment is effective, and that, for purposes 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 therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                     II-3

               practice; enter into any material contracts or engage in any
               transaction which, even though in the ordinary and usual course
               of business, is not consistent with the prior business practice
               of the Sellers or the Subsidiaries; or make any changes in the
               accounting principles and practises of the Sellers or the
               Subsidiaries.

         (iii)  not adopt or file a plan of complete or partial liquidation,
                dissolution, merger or other reorganisation.

         (iv)  not do anything that may cause the Sellers' warranties to
               become incorrect.

         (v)  make all reasonable efforts to preserve intact all licenses and
              permits of the Sellers and the Subsidiaries and maintain the
              business relationships of the Sellers and the Subsidiaries.

         (vi)  pay any taxes (social security premiums included) or other
               amounts owed and to file any tax returns or other similar filings
               required by applicable law.

        (vii)  each Seller shall call and hold a meeting of its shareholders
               at which meeting such shareholders will be asked to approve the
               sale of the Business and the Assets to the Purchaser and the
               assumption of the Assumed Liabilities by the Purchaser,
               provided that each Seller shall use its best efforts to hold
               such meeting as promptly as is practicable following the
               declaration by the SEC of the effectiveness of the Registration
               Statement.

     The Purchaser shall be given full access at all reasonable times to the
premises and records of the Sellers and the Subsidiaries and the Sellers shall
upon request furnish information regarding the Business requested by the
Purchaser.

8  SELLERS' WARRANTIES AND INDEMNIFICATION

     8.1  The Sellers warrant to the Purchaser that at the date hereof:

          a)   Each of the statements in the Schedules (except Schedules 9 and
               13) is true and accurate and the Schedules do not omit any
               material fact;

          b)   the Sellers have, to the best of their knowledge, provided all
               information relating to the Sellers and the Subsidiaries and
               their respective affairs which would be material to the Purchaser
               for the valuation of the Business and the Assets;

     8.2 If any one or more of the warranties in Clause 8.1 or in the Schedules
are untrue, inaccurate, misleading or breached at the Effective Date, the Cash
Consideration to be paid at the Effective Date shall be reduced by the
Deficiency Amount (as such term is defined below); provided that if the
Purchaser provides written notice to the Sellers, or the Sellers provide written
notice to the Purchaser, that the aggregate Deficiency Amount is in excess of
NOK 44,000,000, the Parties shall use their reasonable best efforts to reach an
agreement with respect to the sale of the Business to the Purchaser on mutually
acceptable terms; provided further that if the Parties are unable to reach such
an agreement within

                                      7

10 Business Days following delivery of any such notice, any Party may terminate
this Agreement by delivery to the other Parties of a written notice to such
effect within 5 Business Days after such 10 Business Day time limit has elapsed.
The "Deficiency Amount" shall equal, as applicable, the value at the Effective
Date of the specific Assets (or portions thereof) and the specific Assumed
Liabilities (or portions thereof) that resulted in the warranties in Clause 8.1
and the Schedules being untrue, inaccurate, misleading or breached; provided
that "Deficiency Amount" shall not include any indirect or consequential loss or
damage, including, but not limited to, loss of goodwill or similarly related
indirect losses or damages. If any one or more of the warranties in Clause 8.1
and the Schedules are untrue, inaccurate, misleading or breached at the
Effective Date, but such untrue, inaccurate, misleading or breached warranty is
not discovered until after the Effective Date, the Sellers shall promptly
reimburse to the Purchaser an amount equal to the Deficiency Amount, plus
interest on such amount at the rate of 8% per annum from the Effective Date
until the date of repayment.

     To the extent that any third party presents a claim against the Purchaser
or any Subsidiary related to events that occurred prior to the Effective Date
and such claim has not resulted in the reduction of the Cash Consideration at
the Effective Date or a reimbursement by the Sellers to the Purchaser as
described in the immediately preceding paragraph, the Sellers shall indemnify
and hold harmless the Purchaser and the Subsidiaries, as the case may be,
against all losses, claims, damages, liabilities, costs or other expenses
("Losses") relating to such third party claims that the Purchaser or any
Subsidiary, as the case may be, may reasonably incur or become subject to,
insofar as such Losses (or actions in respect thereof) arise out of, are based
upon or are in connection with any untrue, inaccurate, misleading or breached
warranty made by the Sellers under Clause 8.1 or the Schedules, by reimbursing
the Purchaser an amount equal to such Losses, provided that Losses shall not
include any indirect or consequential loss or damage, including, but not limited
to, loss of goodwill or similarly related indirect losses or damages.

     The Sellers shall without undue delay be notified of any third party claim
for which indemnification will be sought by the Purchaser or any Subsidiary
under this Agreement and the Sellers will have the right to assume control and
direct defence thereof using counsel selected by the Sellers provided that such
counsel shall not have a conflict with the Purchaser in connection with such
legal representation. The Parties shall cooperate with each other and provide
each other with access to relevant books and records in their possession. No
such third party claim shall be settled without the prior written consent of the
Sellers. If a firm written offer is made to settle any such third party claim
and the Sellers propose to accept such settlement, and the Purchaser refuses to
consent to such settlement, then the Sellers shall be excused from and the
Purchaser shall be solely responsible for all further defence of such third
party claim. The maximum liability for the Sellers relating to such third party
claim shall be the amount of the proposed settlement.

     For a period of three years from the Effective Date, the Sellers will
indemnify and hold harmless the Purchaser and the Subsidiaries as the case may
be against any and all Losses (including deficiencies, taxes, interest and
penalties) they may reasonably incur or become subject to, insofar as such
Losses arise out of, are based upon or are in connection with a claim by any
taxing authority for any taxes allocated or attributable to any period ending on
or before the Accounts Date, which has not been included in the Accounts;
provided however, that this indemnity shall only apply if the Purchaser and the
Subsidiaries have given the Sellers the right to take all action to refute such
claim by such taxing authority.

     The Sellers shall promptly reimburse each indemnified party for all legal
or other expenses reasonably incurred by it in connection with investigating or
defending any Losses, including any amounts paid in settlement of any litigation
commenced or threatened if such settlement is effected with a prior written
consent of the Sellers.

     The liability of the Sellers under this Clause 8.2 (other than liability
under the fourth paragraph hereof) shall not arise unless the aggregate amount
of all claims (other than claims under the fourth paragraph hereof) exceeds NOK
4,000,000, in which event the liability of the Sellers shall be limited to the
amount in excess of NOK 4,000,000. The liability of the Sellers under the fourth
paragraph of this Clause 8.2 shall not arise unless the aggregate amount of all
claims under the fourth paragraph of this Clause 8.2 exceeds NOK

                                      8

1,000,000, in which event the liability of the Sellers shall be limited to the
amount in excess of NOK 1,000,000.

     8.3 The liabilities of the Sellers in respect of the warranties (except
those referred to in Clause 8.2, fourth paragraph above) shall terminate one
year after the Effective Date unless written notice of the matter complained of
(giving such details as shall be reasonably practicable) shall have been given
by the Purchaser to the Sellers prior to the expiry of such one year period.

     8.4 The Sellers' liability under this clause shall under no circumstances
exceed in aggregate NOK 75 million. No claim shall be made in respect of
indirect or consequential loss or damage.

     8.5 The Sellers shall not be liable for any claim under this Clause 8, when
the claim or the issues and circumstances giving rise to the claim is disclosed
to the Purchaser in the Accounts, in the Disclosure Letter or during the
Purchaser's due diligence review of the Sellers and its Subsidiaries, provided,
however, the Sellers can prove beyond reasonable doubt that such disclosure has
taken place.

     8.6 The Sellers' liability under this clause shall be guaranteed by the
Shareholders in a joint but not several manner and in the form set forth in
Schedule 13 and none of the Shareholders shall be responsible towards the
Purchaser for more than its percentage of any claim presented which is equal to
its guarantee percentage as set out in Schedule 7.

     8.7 The warranties in Clause 8.1 and the Schedules, and the remedies
available to the Purchaser in case of breach of warranties set out in this
Agreement, are exhaustive and the Sellers shall have no liability to the
Purchaser other than as set out in this Agreement.

9  PURCHASER'S WARRANTIES AND INDEMNIFICATION

     9.1 The Purchaser warrants to the Sellers that at the date hereof each of
the statements in Schedule 9 is true and accurate and Schedule 9 does not omit
any material fact.

     9.2 Purchaser shall indemnify and hold harmless each Seller against all
Losses it may reasonably incur or become subject to under the Securities Act,
the Securities Exchange Act of 1934, as amended, or otherwise, insofar as such
Losses (or actions in respect thereof) arise out of, are based upon or are in
connection with (1) any untrue, inaccurate, misleading or breached warranty made
by the Purchaser under Clause 9.1 or Schedule 9; (2) any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement, the prospectus included therein, or any amendments, supplements or
exhibits thereto or material incorporated by reference therein, or the omission
or alleged omission to state in such documents a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; provided that the
Purchaser will not be liable under this clause (2) to the extent Losses are
based on an untrue statement or omission or alleged untrue statement or omission
made in reliance upon and in conformity with information relating to either
Seller or any Subsidiary furnished in writing by either Seller or any Subsidiary
to the Purchaser expressly for inclusion therein; or (3) the failure of the
Purchaser to comply with the Securities Act or any other law, rule or regulation
with respect to the distribution of the Consideration Shares to the Sellers.

     The Purchaser shall without undue delay be notified of any third party
claim for which indemnification will be sought by either Seller under this
Agreement and the Purchaser will have the right to assume control and direct
defence thereof using counsel selected by the Purchaser provided that such
counsel shall not have a conflict with the Sellers in connection with such legal
representation. The Parties shall cooperate with each other and provide each
other with access to relevant books and records in their possession. No such
third party claim shall be settled without a prior written approval of the
Purchaser. If a firm written offer is made to settle any such third party claim
and the Purchaser proposes to accept such settlement, and the Sellers refuse to
consent to such settlement, then the Purchaser shall be excused from and the
Sellers shall be solely responsible for all further defence of such third party
claim. The maximum liability for the Purchaser relating to such third party
claim shall be the amount of the proposed settlement.

     9.3 Purchaser shall promptly reimburse each indemnified party for all legal
or other expenses reasonably incurred by it in connection with investigating or
defending any Losses, including any amounts

                                      9

paid in settlement of any litigation commenced or threatened if such settlement
is effected with the prior written consent of the Purchaser.

10  THE REGISTRATION STATEMENT; SALE OF CONSIDERATION SHARES

     10.1 The Purchaser shall prepare and file with the SEC as soon as is
reasonably practicable after the date hereof the Registration Statement which
provides for the registration under the Securities Act of the Consideration
Shares to be issued to the Sellers pursuant hereto. The Purchaser shall use its
reasonable best efforts to (a) cause the Registration Statement to become
effective as promptly as practicable, (b) remove any stop order that may be
issued by the SEC with respect thereto, and (c) take all or any action necessary
or required under applicable federal or state securities laws in connection with
the issuance of the Consideration Shares to the Sellers pursuant hereto. The
Purchaser shall immediately notify the Sellers when the SEC has requested any
additional information regarding the Registration Statement, declared the
Registration Statement effective or issued or removed any stop order with
respect thereto. The Purchaser shall use its best efforts to cause the
Consideration Shares to be listed on the New York Stock Exchange.

     10.2 Sellers agree to use their reasonable best efforts to sell any
Consideration Shares in an orderly manner and to provide Purchaser with prior
notice of its intention to sell such stock.

11  THE CONTRACTS

     11.1 The Purchaser shall in respect of the period after the Effective Date
use its reasonable best efforts to meet its obligations under the Contracts.
Insofar as any consents or licences to the transfer or assignment of the benefit
and burden of the Contracts have not been obtained on the Effective Date, or if
such benefit or burden cannot effectively be so transferred or assigned to the
Purchaser except with the consent of or by an agreement with the other party or
parties thereto, then:

        a)  the Sellers shall use their reasonable best efforts to obtain the
            consent of such other party or parties to the Contracts being
            novated or assigned in terms reasonably acceptable to the
            Purchaser; and

        b)  unless and until all of the Contracts shall have been so novated or
            assigned, the Sellers shall provide to the Purchaser from the
            Effective Date the benefit and burden of the Contracts as if the
            same had been effectively novated or assigned to the Purchaser.

     The Sellers do not warrant that the Contracts are assignable or
transferable and shall not be liable or responsible in the event any of the
Contracts are cancelled or terminated due to the Purchaser's acquisition of the
Business.

     11.2 The Purchaser shall indemnify and hold harmless the Sellers against
any and all Losses they may reasonably incur or become subject to, insofar as
such Losses arise out of, are based upon or are in connection with the
non-performance or the defective or negligent performance after the Effective
Date by the Purchaser of any Contracts. The indemnification hereunder shall,
however, not apply if the Purchaser's non-performance or the defective or
negligent performance is caused by the Sellers by any breach of representations
or warranties set out in this Agreement or the schedules hereto.

     11.3 After the Effective Date the Sellers will assist the Purchaser in
notifying all existing customers of the Business in writing (in such form and at
such times as the Purchaser may reasonably require) of the sale of the Business
to the Purchaser and the arrangements being made in respect thereof and the
Sellers will use their reasonable best efforts to obtain the written consent of
such customers to such arrangements.

12  INDEMNITY BY THE PURCHASER

     In the event the Sellers receive any invoice or in the event a claim is
presented to the Sellers in any other way after the Effective Date and such
claim relates to the Assumed Liabilities, the Sellers shall without undue delay
send the invoice or written documents relating to the claim to the Purchaser and
the Purchaser shall pay the claim directly to the third party on the due date.

                                      10

     The Purchaser shall indemnify and hold harmless the Sellers against all
Losses they may reasonably incur or become subject to, insofar as such Losses
arise out of, are based upon or are in connection with any of the Assumed
Liabilities under this Agreement. The Purchaser shall furthermore indemnify and
hold harmless the Sellers against all Losses (including deficiencies, taxes,
interest and penalties) they may reasonably incur or become subject to, insofar
as such Losses arise out of, are based upon or are in connection with a claim by
any taxing authority for any taxes allocated or attributable to any period
ending on or before the Effective Date; provided, however, that this indemnity
shall only apply if the Sellers have given the Purchaser the right to take all
action to refute such claim by such taxing authority.

     The indemnification hereunder shall, however, not apply if the Loss is
caused by the Sellers by any breach of representations or warranties set out in
this Agreement or the schedules hereto.

13  BOOKS AND RECORDS

     The Sellers shall on the Effective Date (insofar as the Sellers are not
required to retain the same under Norwegian law or otherwise) deliver to the
Purchaser all of the books, records, files, papers and other documents of the
Sellers and the Subsidiaries related to the Business and in particular the
Sellers shall deliver to the Purchaser the original executed copies of the
Contracts.

     The Purchaser will for a period of ten years keep safely in Norway all such
books, records, files, papers and other documents related to the Business as the
Sellers shall transfer or cause to be transferred to the Purchaser and shall
afford the Sellers reasonable access thereto, during reasonable business hours
after notice, for as long as shall be necessary to enable the Sellers to deal
with its taxation and other liabilities in respect of the period up to the
Effective Date and will permit the Sellers and its servants, agents and
professional advisers upon reasonable notice to make copies at the Sellers'
expense of such books, records, files, papers and other documents for the
purpose of answering any query raised or disposing of any dispute in relation
thereto.

14  NON-COMPETITION

     For a period of two years following the Effective Date neither the Sellers
nor any person, group, partnership, corporation or entity that controls or is
controlled by or under common control with the Sellers ("Seller Affiliate") will
compete, directly or indirectly, with the Purchaser or any person, group,
partnership, corporation or entity that controls or is controlled by or under
common control with the Purchaser ("Purchaser Affiliate") in designing,
manufacturing, selling, renting or running liner hangers, packers and gas lift
valves and systems. Furthermore, no Seller or Seller Affiliate will solicit for
employment any employee of the Purchaser or Purchaser Affiliate, including any
employee of a Seller or a Subsidiary who becomes an employee of the Purchaser or
a Purchaser Affiliate.

15  COSTS AND TAXES

     Each party shall pay its own costs in relation to the negotiations leading
up to the sale and purchase of Assets contemplated by this Agreement and the

with its Norwegian subsidiary for all of the Purchaser's obligations and
liabilities under this Agreement.

Ladies and Gentlemen:

     We have acted as counsel for Weatherford Enterra Inc., a Delaware
corporation (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended (the "Act"), of 750,000 shares (the "Shares")
of the Company's common stock, $.10 par value, to be issued upon the terms and
subject to the conditions set forth in the Prospectus contained in the
Registration Statement on Form S-4 (the "Registration Statement") relating
thereto to be filed with the Securities and Exchange Commission by the Company
on April 19, 1996. The Shares are to be issued in connection with the
acquisition (the "Acquisition") by the Company of all of the assets of Nodeco
AS, a Norwegian joint stock company ("Nodeco"), and Aarbakke AS, a Norwegian
joint stock company ("Aarbakke"), pursuant to a Purchase and Sale Agreement
dated March 28, 1996 (the "Purchase Agreement"), among the Company, Nodeco and
Aarbakke.

     In connection therewith, we have examined originals or copies certified or
otherwise identified to our satisfaction of the Registration Statement, the
Purchase Agreement, the Restated Certificate of Incorporation of the Company,
the Bylaws of the Company, the corporate proceedings with respect to the
Acquisition and the proposed issuance of the Shares and such other documents and
instruments as we have deemed necessary or appropriate for the expression of the
opinion contained herein.

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

     Based on the foregoing, and having regard for such legal considerations as
we have deemed relevant, we are of the opinion that the Shares proposed to be
issued by the Company in connection with the Acquisition have been duly
authorized for issuance and, when issued in accordance with the terms of the
Purchase Agreement, will be validly issued, fully paid and nonassessable.

     The foregoing opinion is limited to the federal laws of the United States
of America, the laws of the State of Texas and the General Corporation Law of
the State of Delaware, and we are expressing no opinion as to the effect of the
laws of any other jurisdiction.

     This opinion is rendered solely for the benefit of the Company and is not
to be used, circulated, copied, quoted or referred to without our prior written
consent. We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the caption "Legal
Matters" in the Prospectus contained in the Registration Statement.

                                          Very truly yours,

                                         /s/ Fulbright & Jaworski L.L.P.
                                             Fulbright & Jaworski L.L.P.
