             Agreement.

2.   CONDITIONS PRECEDENT

     2.1     Without prejudice to the obligations of the Vendors under this
             Agreement the obligation of the Purchaser to complete the sale and
             purchase of the Sale Shares herein provided for is conditional
             upon:-


             2.1.1 it being confirmed by way of confidential guidance (subject
                   only to such conditions as may be acceptable to the
                   Purchaser) from the Office of Fair Trading to the
                   satisfaction of the Purchaser that the Secretary of State for
                   Trade and Industry would not be likely to refer the

                   this Agreement to the Competition Commission for
                   investigation.

                   reasonably require for a period of not less than five
                   Business Days commencing on the day after the third Business
                   Day after the day on which the Purchaser's Solicitors receive
                   the confidential guidance referred to in Clause 2.1.1 to
                   enable the Purchaser to carry out such due diligence as the
                   Purchaser may deem appropriate. Such due diligence will be
                   carried out in co-operation with and in consultation with
                   Mr Ian Suttie.

             2.1.3 the Purchaser not discovering any Material Adverse Effect of
                   the Target Group. For the purpose of this clause the
                   expression "Material Adverse Effect" shall mean any event,
                   circumstance or fact which individually or in the aggregate
                   results in a materially adverse effect on the Target Group's
                   business (including customer relationships), operations,
                   properties, condition (financial or


   6

                                       4

                   otherwise), assets or liabilities taken as a whole.

             2.1.4 The Majority Vendors delivering to the Purchaser (sent by
                   e-mail to Burt Martin at burt.martin@weatherford.com and to
                   Roderick Bruce at roderick.bruce@dmws.com) management
                   accounts for the Target Group as at 31st December 2000
                   together with a list of rental assets (and their location) of
                   the Target Group as at 31st December 2000 in form and
                   substance reasonably satisfactory to the Purchaser.

     2.2     The Purchaser reserves the right to waive any or all of the
             conditions in Clause 2.1.

     2.3     It is expressly agreed and declared that any act or omission by the
             Purchaser indicating that the conditions in Clause 2.1 (or any of
             them) have been satisfied or shall be deemed to be satisfied or
             shall be waived shall be wholly without prejudice to its rights
             under any other clause of this Agreement or the Tax Deed.

     2.4     In the event that the conditions in Clause 2.1 have not been
             fulfilled or waived by 30th April 2001 any of the parties shall be
             entitled by notice in writing to all of the other parties to
             terminate this Agreement whereupon the Purchaser shall cease to
             have any liability under this Agreement. Notwithstanding the
             foregoing terms of this clause 2.4, (a) any notice by the Purchaser
             to terminate this Agreement in the event of the Purchaser not being
             reasonably satisfied with the management accounts and list of
             assets referred to Clause 2.1.4 above must be served on the
             Majority Vendor's Solicitors no later than two Business Days after
             receipt by the Purchaser of the said management accounts and list
             of assets; and (b) any notice by the Purchaser to terminate this
             Agreement as a result of the Purchaser discovering a Material
             Adverse Effect must be served on the Majority Vendors not later
             than 5 p.m. (UK time) on the sixth Business Day after the day on
             which such due diligence is commenced; and in either case, in the
             event that no such


   7

                                       5

             notice is served or is not served timeously, the Purchaser shall be
             deemed to have waived such condition in terms of Clause 2.2.

3.   SALE AND PURCHASE

     3.1     Subject to the terms and conditions of this Agreement, (and in
             particular Clause 2) each of the Vendors as the legal and
             beneficial owners (except for the Trustees who shall sell in their
             capacity as trustees) shall sell and the Purchaser shall purchase
             the Sale Shares set opposite his name in Columns 3 and 4 of Part 1C
             of the Schedule, with all rights and privileges attached to them at
             the Completion Date, free and clear of all and any encumbrances.
             The Purchaser, relying on the undertakings, representations,
             warranties and covenants contained in this Agreement agrees to buy
             the Sale Shares on those terms.

     3.2     Each of the Vendors hereby waives all rights of pre-emption, other
             restrictions on transfer and rights of veto or otherwise held by
             each such Vendor under the Articles of Association of members of
             the Target Group or otherwise in respect of the transfer of the
             Sale Shares to the Purchaser or its nominee(s) hereunder.

4.   CONSIDERATION

     4.1     The consideration for the sale and purchase of the Sale Shares
             shall be the Consideration payable in accordance with Clause 4.3
             below.

     4.2     The Vendors shall be entitled to the Consideration in the
             percentages set out in column 5 of Part 1C of the Schedule.

     4.3     Upon completion of the matters referred to in paragraphs 1, 2, 3
             and 4 of Part 3 of the Schedule inclusive the Purchaser shall cause
             there to be issued to the Vendors the Weatherford Shares in such
             name or names as may be requested in writing by the Vendors and
             deliver certificates to the Majority Vendors Solicitors on behalf
             of the Vendors.

     4.4.1   Within ten Business Days after the Completion Date the Purchaser
             will prepare and deliver to the Majority Vendors' Solicitors a
             statement


   8

                                       6

             (attaching copies of the relevant bank statements) showing the
             aggregate credit balance (calculated by setting off debit balances
             against credit balances) on all bank accounts of the Non-UK
             Subsidiaries (other than in the UK and Jersey) as the close of
             business on the last Business Day before Completion as listed in
             the Disclosure Letter.

     4.4.2   The Majority Vendors' Solicitors may within five business days
             after receipt by them of said statement notify the Purchaser that
             they do not agree with the statement. If no such notice is received
             by the Purchaser within such five day period the statement will be
             deemed to be agreed. If such notice is received within such five
             day period the matters in dispute will be referred to an
             independent expert whose decision shall be final and binding on the
             parties. In the event that the parties are unable to agree upon the
             appointment of an independent expert, such expert shall be
             appointed, on the application of the Purchaser or the Majority
             Vendors' Solicitors by the President of the Institute of Chartered
             Accountants of Scotland.

     4.4.3   The credit balance on the statement agreed or determined pursuant
             to Clause 4.4.2 will constitute additional consideration for the
             Sale Shares ("the Additional Consideration"). Within ten business
             days after the Additional Consideration has been agreed or
             determined the Purchaser will procure the issue to the Vendors (in
             the percentages set out Part 1C of the Schedule) of such number of
             Weatherford Shares as is equal to the US Dollar value of the
             Additional Consideration (calculated on the basis of the rates of
             exchange current on the third business day prior to the date on
             which such Weatherford Shares are to be issued) divided by the Fair
             Market Value.

     4.5     No fractional shares of Weatherford shall be issued to the Vendors
             and to the extent a fractional share would otherwise be issued, the
             number of Weatherford Shares to be issued would be rounded up or
             down to the nearest whole.

     4.6     For the purpose of calculating the number of Weatherford Shares to
             be issued


   9

                                       7

             the rate of conversion from Sterling to Dollars will be fixed on
             the third business day prior to the Completion Date ("the Fix
             Date") and shall be the average rate of exchange over the ten
             Business Days preceding the Fix Date. For this purpose the rate of
             exchange for each Business Day will be the Pound Spot Closing
             mid-point rate published in the Financial Times on the day in
             question. In the event that in respect of any day during the ten
             Business Days referred to the said rate of conversion is lower than
             $1.35 then the rate for that day for the purposes of this Clause
             4.6 shall be deemed to be $1.35 and in the event that the said rate
             of conversion is higher than $1.55 then the rate for that day for
             the purposes of this Clause 4.6 shall be deemed to be $1.55.

5.   PRE-COMPLETION

     5.1     Prior to Completion the Warrantor shall not knowingly and shall
             procure (as far as he can) that the Company and the Subsidiaries
             shall not do any act or thing or omit to do any act or thing the
             commission or omission of which would constitute a breach of any of
             the Warranties or which would make any of the Warranties untrue or
             inaccurate or misleading.

     5.2     The Majority Vendors will procure that between the date of signing
             this agreement and Completion the collection of book debts by
             members of the Target Group will be carried out only in the
             ordinary course of business in accordance with the normal practice
             of each such member.

6.   COMPLETION

     6.1     The purchase and sale of the Sale Shares shall be completed at the
             offices of the Majority Vendors' Solicitors or at such other place
             as the parties may agree on the Completion Date when the parties
             shall each comply with their respective obligations set out in Part
             3 of the Schedule.

     6.2     The Purchaser shall not be obliged to complete the purchase of any
             of the Sale Shares unless all of the Sale Shares are sold and
             purchased simultaneously.

7.   WARRANTIES AND UNDERTAKINGS BY THE WARRANTOR

     7.1     The Warrantor hereby warrants and represents to and undertakes with
             the


   10
                                       8

             Purchaser that the Warranties as at the date of this Agreement:

             7.1.1  save as fairly disclosed in the Disclosure Letter, are true
                    and accurate in all respects;

             7.1.2  are (without prejudice to the provisions of paragraph 10.3
                    of Part 6 of the Schedule and the content of the Disclosure
                    Letter) not and are not to be affected or limited by any
                    previous or other disclosures express or implied, written or
                    oral to the Purchaser, its officers or representatives or
                    professional advisers or by any investigation made by or on
                    behalf of the Purchaser into the affairs of the Target Group
                    or by any information of which the Purchaser or its agents
                    have knowledge (actual or constructive); and

             7.1.3  shall not in any respect be extinguished or affected by
                    Completion.

     7.2     The provisions of Part 6 of the Schedule shall apply to limit the
             Warrantor's liability in respect of the Warranties, the Indemnities
             and the Tax Deed to the extent specified therein and/or any claim
             for breach thereof.

     7.3     7.3.1    Notwithstanding any other provision of this Agreement and
                      without limiting the rights of the Purchaser in any way
                      the Warrantor hereby undertakes to the Purchaser that if
                      there is a breach of any of the Warranties which relates
                      to a quantified liability or increased liability incurred
                      by any member of the Target Group the Warrantor will pay
                      in cash to the Purchaser (or , if so directed by the
                      Purchaser, to the relevant Target Group Company) within 5
                      Business Days after written demand, an amount equal to
                      the aggregate of:

                      7.3.1.1  the amount which if received by the relevant
                               Target Group Company would be necessary to put
                               that company into the position which would have
                               existed
   11

                               had there been no breach of the Warranties; and

                      7.3.1.2  all costs, liabilities, damages and expenses
                               suffered or incurred by the Purchaser and/or the
                               relevant Target Group Company and which would not
                               have been suffered or incurred if the relevant
                               warranty had been true and accurate.

             7.3.2    Interest will run on any amount due to the Purchaser under
                      Clause 7.2.1 at the Rate from the due date for payment
                      under that sub-Clause until the date upon which payment
                      in full has been made to the Purchaser (or as the case
                      may be, to the relevant Target Group Company, if
                      directed).

     7.4     For the avoidance of doubt it is expressly agreed and declared that
             save for the Disclosure Letter and the Second Disclosure Letter (if
             any), no letter, document or other communication shall be deemed to
             constitute a disclosure for the purposes of the Warranties. The
             Purchaser acknowledges that it has had an opportunity to review all
             documents listed in the annexures to the Disclosure Letter and the
             Disclosure Bundle.

     7.5     The Warrantor undertakes not to make and will procure (to the
             extent that he is able) that no other person claiming under or
             through him will make any claim against any Target Group Company or
             any officer or employee of any Target Group Company on whom he may
             have relied before entering into any term of this Agreement or the
             Tax Deed or in the preparation of the Disclosure Letter or the
             Second Disclosure Letter in respect of any claim under this
             Agreement or any omission from or statement in the Disclosure
             Letter or the Second Disclosure Letter.

     7.6     Each of the Warranties shall be construed as separate and
             independent and save as expressly otherwise provided shall not be
             limited by reference to any other such Warranty or by anything in
             this Agreement.

     7.7     In determining damages for any breach of the Warranties the
             Purchaser shall

   12

                                       10

             not be required to cease to conduct or to wind down any business or
             to rely on the limited liability of any group company in mitigation
             of its loss. The Purchaser hereby acknowledges that entering into
             this Agreement it is not relying on any warranty, representation or
             undertaking whatsoever and by whomsoever made save for the
             representations, warranties and undertakings set out in this
             Agreement.

     7.8     Any payment made by any of the Majority Vendors to the Purchaser
             under the Warranties, the Indemnities or under the Tax Deed or
             otherwise by the Vendors under this Agreement will be treated as a
             reduction by the amount so paid of the Consideration for the Sale
             Shares.

8.    DISCLOSURES AFTER SIGNING

     8.1     The Warranties shall be deemed to be repeated immediately prior to
             Completion with reference to the facts and circumstances then
             existing but subject to any exceptions disclosed in the Second
             Disclosure Letter delivered to the Purchaser by the Warrantor and
             accepted by the Purchaser pursuant to Clause 8.2 (but without
             prejudice to the Purchaser's rights under Clause 8.3 and subject
             always to the limitations in Part 6 of the Schedule).

     8.2     The Warrantor shall disclose to the Purchaser in terms of the
             Second Disclosure Letter (with reasonably sufficient details to
             enable the Purchaser to assess the impact thereof) as soon as
             practicable after becoming aware of the same and in any event prior
             to Completion any matter or thing which may arise after the date
             hereof and before Completion which constitutes, or might reasonably
             be expected to constitute a breach of any of the Warranties and in
             respect of which, other than in respect of any matter referred to
             in Clause 8.3, the Purchaser shall have no claim against the
             Warrantor except to the extent of any additional liability (both as
             to substance and quantum) beyond that disclosed in the Disclosure
             Letter. For the avoidance of doubt, there shall be deemed to be
             disclosed to the Purchaser any matters or things undertaken with
             the prior written consent of the Purchaser and, notwithstanding
             that

   13

                                       11


             they might otherwise constitute a breach of the Warranties or any
             other provision of this Agreement, the provision of Clause 8.3
             shall not apply in respect of any such matters.


     8.3     In the event of any such matter or thing as is mentioned in Clause
             8.2 being disclosed to the Purchaser before Completion which in any
             such case is material in the context of the transactions
             contemplated herein as a whole, then the Purchaser may at its sole
             option:-

             8.3.1    resile from this Agreement by notice in writing to the
                      Vendors in which case neither party shall have any
                      liability to the other hereunder; or

             8.3.2    proceed to Completion in which case the Warrantor shall be
                      absolved from all liability he would otherwise have had in
                      respect of such matter or thing under the Warranties.

             9.1.6    Reports; Financial Statements

                      9.1.6.1  Since 31 December 1999 Weatherford and its
                               subsidiaries have filed (i) all forms, reports,
                               statements, notices and other documents required
                               to be filed with the SEC (collectively, the
                               "Weatherford SEC Reports"). The Weatherford SEC
                               Reports were prepared in all material respects in
                               accordance with the requirements of applicable
                               laws (including the Securities Act and the
                               Securities Exchange Act of 1934, as amended, as
                               the case may be). As of their respective dates,
                               the Weatherford SEC Reports did not contain any
                               untrue statement of a material fact or omit to
                               state a material fact required to be stated
                               therein or necessary to make the statements made
                               therein, in light of the circumstances in which
                               they were made, not misleading. Since the filing
                               of Weatherford's latest quarterly report on Form
                               10-Q, there has been no Weatherford Material
                               Adverse Effect that has not been disclosed

                      at and as of the date of this Agreement and at the date of
                      Completion except to the extent such representations and
                      warranties specifically refer to a date other than the
                      date of this Agreement.


             9.1.9    Certain Proceedings. There is no pending Proceeding (as

                                       17

                      hereinafter defined) that has been commenced against
                      Weatherford or the Purchaser, or against any of their
                      Officers, directors or stockholders in connection with the
                      affairs of Weatherford or the Purchaser, and that
                      challenges, or may have the effect of preventing,
                      delaying, making illegal or otherwise interfering with,
                      any of the transactions contemplated by the Agreement
                      and/or the Registration Rights Agreement or that involves
                      material claims not disclosed in the Weatherford SEC
                      Reports against Weatherford or its affiliates. To the
                      knowledge of Weatherford and the Purchaser, no such
                      Proceeding has been threatened. For the purposes of this
                      Agreement, a Proceeding means any action, binding
                      arbitration, audit, hearing, formal investigation,
                      litigation or suit (whether civil, criminal or
                      administrative) commenced, brought, conducted or
                      heard by or before any court, arbitrator, mediator or
                      governmental authority.


     9.2     Weatherford will register for resale all of the Weatherford Shares
             pursuant to the terms of the Registration Rights Agreement. If and
             when paragraph (k) of Rule 144 under the Securities Act (or a
             comparable provision of any successor rule) becomes applicable to
             any Weatherford Shares that continue to be held by any Vendor, then
             upon receipt of the certificates evidencing such shares,
             Weatherford will promptly deliver or cause to be promptly delivered
             to such Vendor (or, if so instructed, to his assignees) new
             certificates not bearing any legend restricting transfer.

     9.3     Weatherford and the Purchaser agree to provide the Vendors with the
             following price protection with respect to the Weatherford Shares:

             9.3.1    In the event that on the first anniversary of the
                      Completion Date ("the Protection Termination Date") the
                      Market Value (as hereinafter defined) of Weatherford
                      Common Stock is less than Fair Market Value per share
                      ("the Floor Price"), (the difference


   20
                                       18


                      between the Market Value and the Floor Price multiplied by
                      the number of Weatherford Shares held by the Vendors at
                      the Protection Termination Date being hereinafter referred
                      to as the "Deficiency"), Weatherford and the Purchaser
                      jointly and severally agree and undertake at the option
                      of each Vendor within five Business Days of the Protection
                      Termination Date, to either (1) issue to the Vendors or
                      their respective nominees an additional number of
                      registered shares of Weatherford Common Stock equal to the
                      Deficiency divided by the Market Value of the Weatherford
                      Common Stock, which shares of Weatherford Common Stock
                      will be freely tradable on a national securities exchange
                      or otherwise without restrictions or (2) pay an amount of
                      cash equal to the Deficiency by wire transfer of same day
                      funds into such bank accounts as the Vendors may
                      respectively nominate in US dollars or at each Vendor's
                      option in pounds sterling converted at the average rate of
                      exchange over the ten Business Days preceding the
                      Protection Termination Date calculated using the Pound
                      Spot Closing mid-point rate published in the Financial
                      Times on the day in question (such share issuance or cash
                      payment being hereinafter referred to as an "Adjusted
                      Payment").


             9.3.2    In the event that the Weatherford Shares are not issued or
                      the cash not paid (as the case may be) to the Vendors in
                      respect of the Deficiency within five Business Days of the
                      later of (a) the date on which each Vendor gives notice
                      intimating whether he wishes his Adjusted Payment settled
                      in cash or (if applicable) Weatherford Shares and (b) the
                      Protection Termination Date, interest shall run on the
                      amount of the Deficiency at the Rate for the period from
                      the Protection Termination Date until the date of issuance
                      or payment (as the case may be).

                                       19

             9.3.4    For the purpose of this Clause 9.3 "Market Value" means
                      the average closing sale price of Weatherford Common Stock
                      on the New York Stock Exchange for the ten consecutive
                      Business Days ending on the Protection Termination Date as
                      published in the Financial Times adjusted (if appropriate)
                      in accordance with sub-clause 9.3.5.


             9.3.5    For purposes of this Clause 9.3, all references to Market
                      Value as of any date shall mean the sum of the Market
                      Value and the market value of any stock, securities or
                      other property or the amount of any cash that may have
                      been received by a Vendor or to which a Vendor is entitled
                      prior to or as of the date in question in respect of a
                      share of Weatherford Common Stock issued to him as
                      Consideration or Additional Consideration. The
                      determination of the market value of any such stock or
                      security shall be based on the closing sale price of that
                      stock or security on the principal stock exchange on which
                      it is listed if that security is traded on a national
                      securities exchange as reported in the Financial Times. If
                      any other security or property is received, its value
                      shall be determined by agreement by a nationally
                      recognised investment banking firm selected in good faith
                      by Weatherford. In the event of a reclassification of the
                      Weatherford Common Stock into a greater or less number of
                      shares of Weatherford Common Stock, all references to
                      numbers of shares of Weatherford Common Stock and all
                      market prices for the Weatherford Common Stock including
                      the Floor Price, shall be appropriately adjusted to
                      reflect such reclassification.


             9.3.6    For purposes of this Clause 9.3, in the event there is a
                      distribution of any stock, securities, cash or other
                      property by Weatherford to the Weatherford stockholders
                      (including the Vendors as holders

   22

                                       20

                      of the Weatherford Shares), the Floor Price shall be
                      reduced (except as may be reduced by the application of
                      Clause 9.3.5) by the market value (as of the distribution
                      date) of such stock, securities, cash or other property so
                      received by a Vendor in respect of a share of the
                      Weatherford Common Stock issued to him at the Completion
                      Date.


     9.4     In this Clause 9.4: (i) a "Registration Failure" means that the
             Shelf Registration has not been declared effective by the SEC or
             if, having been declared effective Weatherford has exercised its
             right under the Registration Rights Agreement to suspend sales
             under the Shelf Registration or a stop order has been issued by the
             SEC or other proceedings are brought by the SEC any of which
             prevent sales pursuant to the Shelf Registration on the applicable
             Put Date; (ii) First Put Date means the date that is ninety days
             after the Completion Date; (iii) Second Put Date means the date
             that is one hundred and eighty days after the Completion Date; and
             (iv) Third Put Date means the date that is two hundred and seventy
             days after the Completion Date.


             9.4.1    If a Registration Failure exists on the First Put Date
                      then each Vendor shall have the right and option
                      exercisable for thirty days after the First Put Date, to
                      compel the Purchaser and Weatherford to repurchase for
                      cash all or any portion of one-third of the Weatherford
                      Shares received by such Vendor as Consideration or
                      Additional Consideration at a price per share equal to the
                      Floor Price plus a cash payment that is equal to interest,
                      calculated at the base rate from time to time of Bank of
                      Scotland plus 2%, from the Completion Date until paid, on
                      the amount that is equal to three times the aggregate
                      Floor Price of the shares as to which the option is
                      exercised.

             9.4.2    If a Registration Failure exists on the Second Put Date,
                      then each Vendor shall have the additional right and
                      option exercisable for


   23

                                       21

                      thirty days after the Second Put Date, to compel the
                      Purchaser and Weatherford to repurchase for cash all or
                      any portion of one-third of the Weatherford Shares
                      received by such Vendor as Consideration or Additional
                      Consideration (or an additional one-third of such
                      Weatherford Shares where the Vendor has exercised the
                      right and option under Clause 9.4.1) at a price per share
                      equal to the Floor Price plus a cash payment that is equal
                      to interest, calculated at the base rate from time to time
                      of Bank of Scotland plus 2% from the Completion Date until
                      paid, on the amount that is equal to two times the
                      aggregate Floor Price of the shares as to which the
                      option is exercised.


             9.4.3    If a Registration Failure exists on the Third Put Date,
                      then each Vendor shall have the right and option,
                      exercisable for thirty days after the Third Put Date, to
                      compel the Purchaser and Weatherford to repurchase for
                      cash all or any portion of one-third of the Weatherford
                      Shares received by such Vendor (or an additional one-third
                      of such Weatherford Shares where the Vendor has exercised
                      the right and option under either or both of Clauses 9.4.1
                      and 9.4.2), at a price per share equal to the Floor Price
                      plus a cash payment that is equal to interest, calculated
                      at the base rate from time to time of Bank of Scotland
                      plus 2%, from the Completion Date until paid, on the
                      amount that is equal to the aggregate Floor Price of the
                      shares as to which the option is exercised.


             9.4.4    Each option created by this Clause 9.4 in favour of a
                      Vendor is exercisable by written notice from such Vendor
                      to the Purchaser during the exercise period of such
                      option. If an option is exercised, the completion of the
                      purchase and sale of the shares shall occur on the fifth
                      Business Day thereafter. The Vendor shall

                                       22

                      deliver certificates representing the shares, duly
                      endorsed for transfer to Weatherford, against which
                      delivery Weatherford and the Purchaser shall pay the
                      amount due to the selling Vendor by wire transfer of same
                      day funds (to such bank account as may be designated by
                      such Vendor) in US dollars or at the option of the Vendor
                      in pounds sterling converted at the average rate of
                      exchange over the ten Business Days preceding the Put Date
                      in question calculated using the Pound Spot Closing
                      mid-point rate published by the Financial Times on the day
                      in question. In the event that any such payment is not
                      made timeously interest shall run on the total sum due at
                      the Rate from the due date for payment until settled in
                      full.


     9.5     Weatherford hereby unconditionally and irrevocably agrees to cause
             the Purchaser to comply with the Purchaser's whole obligations
             under this Agreement and to be jointly and severally liable for the
             performance by the Purchaser of its agreements and obligations
             hereunder as if Weatherford were the primary party hereto and shall
             not be discharged or otherwise impaired or prejudiced by any
             assignation of the Purchaser's rights and/or obligations hereunder
             pursuant to Clause 16.2 but shall continue in full force and
             effect. Weatherford and the Purchaser, jointly and severally, will
             indemnify the Vendors (or any of them) for any loss, damage, cost
             or expense (including, without limitation, reasonable attorneys'
             fees) incurred by any Vendor by reason of the failure of

10.  CLAIMS PROCEDURE

     10.1    In the event of the Purchaser becoming aware of any claim or any
             matter which may involve the Warrantor in liability for breach of
             the Warranties or the Indemnities or in the case of a breach of any
             of the Title Warranties, the Majority Vendors (in this Clause, a
             "Claim"), the Purchaser will notify the relevant Majority Vendors
             in writing as soon as reasonably practicable after becoming aware
             of the same and shall provide reasonable details of the facts and
             circumstances of the Claim as shall then be known to the Purchaser
             provided that a failure to provide such notice shall not limit the
             obligations of the Majority Vendors except to the extent they are
             actually prejudiced.

     10.2    In the case of a Claim resulting from a claim made or which may be
             made by a third party (in this Clause, a "Third Party Claim") the
             relevant Majority Vendors shall within 10 Business Days of having
             received notice thereof pursuant to Clause 10.1 intimate in writing
             to the Purchaser whether or not the relevant Majority Vendors
             desire to conduct the defence of such Third Party Claim.

     10.3    If the relevant Majority Vendors do not give timeous notice in
             accordance with Clause 10.2, the relevant Majority Vendors shall be
             deemed to have given notice in accordance with such Clause that
             they do not wish to conduct the defence of such Third Party Claim.
             Always provided that where the relevant Majority Vendors do not
             give timeous notice in accordance with Clause 10.2 any dispute
             relating to such Third Party Claim shall be conducted by the
             Purchasers but the Purchaser shall keep the relevant Majority
             Vendors informed on a reasonable basis as may be requested from
             time to time.

     10.4    If the relevant Majority Vendors have given timeous notice that the
             relevant Majority Vendors desire to conduct the defence of a Third
             Party Claim then:


             10.4.1 the Purchaser shall and shall procure (to the extent then
                    within its power) that each Target Group Company shall take
                    such lawful action as the relevant Majority Vendors may
                    reasonably request to
   26

                                       24

                    avoid, dispute, resist, appeal, compromise or defend the
                    Third Party Claim subject to the Purchaser and each Target
                    Group Company being specifically indemnified and secured to
                    their reasonable satisfaction against any Losses which they
                    or any of them may thereby incur;

             10.4.2 the relevant Majority Vendors shall fully and effectually
                    indemnify and secure the Purchaser and each relevant Target
                    Group Company to its satisfaction against any and all Losses
                    which they may incur as a result of such Third Party Claim
                    and the defence thereof and hereby undertake that they shall
                    meet in full, without recourse to the Purchaser or any
                    Target Group Company, the full amount of such Third Party
                    Claim and the whole costs and expenses of the Purchaser and
                    the Target Group Company in defending the same including
                    without prejudice any professional or other costs incurred
                    by any or each of them in being advised with regard thereto;

             10.4.3 the relevant Majority Vendors shall from time to time and
                    forthwith upon the request of the Purchaser keep the
                    Purchaser fully informed of the conduct of and any
                    negotiations relating to the defence of such Third Party
                    Claim.


     10.5    If the relevant Majority Vendors have intimated or are deemed to
             have intimated that they do not wish to defend any Third Party
             Claim, the Purchaser and each relevant Target Group Company may
             take such action as they see fit with regard thereto provided that,
             although the relevant Majority Vendors shall not be deemed to have
             admitted any liability to the Purchaser with regard to such Third
             Party Claim subject as aforesaid, the liability of the relevant
             Majority Vendors shall not be diminished or extinguished on the
             grounds that the Purchaser or any Target Group Company took or
             ought to have taken or omitted to take any action with regard to
             such Third Party

   27

                                       25

             Claim

     10.6    The Purchaser shall be entitled to refuse to allow the Majority
             Vendors to take over the conduct of a Third Party Claim under
             Clause 10.4, and shall be entitled to refuse to comply with a
             request made by the Majority Vendors in relation to a Third Party
             Claim if it is reasonable for the Purchaser to exercise such right
             of refusal taking into account the likelihood of success of the
             Third Party Claim and the protection of the goodwill of the Target
             Group's business but to the extent that the Majority Vendors are
             prejudiced by any such refusal they shall be relieved of the
             liability which they would otherwise have had under the terms of
             this Agreement provided that in the event that the relevant
             Majority Vendor does not agree that it is reasonable for the
             Purchaser to exercise such right of refusal on the basis of the
             likelihood of success of the Third Party Claim the relevant
             Majority Vendor and the Purchaser shall at the request of the
             relevant Majority Vendor remit to a Queens Counsel (to be agreed by
             the parties) the question of whether or not there is a reasonable
             prospect of defending the Third Party Claim. In the event that such
             Queens Counsel is of the opinion that there is a reasonable
             prospect of successfully defending the Third Party Claim the
             Purchaser will not be entitled to refuse to comply with the
             relevant request on the grounds that defence is unlikely to
             succeed. In the event that such Queens Counsel is of the opinion
             that there is no reasonable prospect of successfully defending the
             Third Party Claim the Majority Vendors will not be so relieved of
             such liability.

     10.7    For the avoidance of doubt, should the Purchaser fail to give
             notice of a claim as soon as practicable as required by Clause
             10.1, the relevant Majority Vendors shall (without prejudice to
             paragraphs 5 to 7 of Part 6 of the Schedule) not be absolved or
             released of liability but shall be entitled to claim a reduction
             (up to 100%) in liability they would otherwise have, to the extent
             that they are prejudiced by the delay of the Purchaser.
   28

                                       26

11.  TITLE WARRANTIES AND WARRANTY BY INSTITUTIONAL VENDOR


     The provisions of Part 6 of the Schedule shall have effect in relation to
     any Claim made by the Purchaser for a breach of the Warranties (other than
     the Title Warranties).

     11.1    Each of the Majority Vendors represents, warrants and undertakes to
             the Purchaser in the terms of Part 5A of the Schedule.

     11.2    The Institutional Vendor warrants to the Purchaser that it has the
             capacity and authority and is entitled absolutely and
             unconditionally to sell and transfer the full legal and beneficial
             ownership of the Sale Shares set opposite its name in Part 1C of
             the Schedule and that the Purchaser shall receive the Sale Shares
             of the Institutional Vendor free and clear of any liens or
             encumbrances.

12.  PROTECTION OF GOODWILL

     12.1    Mr Ian Suttie, Mr. David Suttie and Mrs. Suttie hereby undertake to
             the Purchaser with the intent of assuring to the Purchaser the full
             benefit and value of the goodwill and connections of each of the
             Target Group Companies and as a constituent part of the Agreement
             for the sale of the Sale Shares that neither of them will and that
             they will procure that none of their respective Connected Persons
             will:

                    any business which competes directly or seeks to compete
                    directly with any business carried on by any of the Target
                    Group Companies at the date of this Agreement. For the
                    purposes of this

   29

                                       27

                    Clause 12 the parties agree that the business carried on by
                    the Target Group Companies at the date of this agreement
                    shall without prejudice to the foregoing generality be

             12.1.3 (without prejudice to the generality of the provisions
                    contained in Clauses 12.1.1 and 12.1.2 of this Clause) for
                    the period of five years next following the date of this
                    Agreement directly or indirectly solicit, interfere with or

                    such company engaged in its management or the management of
                    any of its branches or in a sales capacity or otherwise in a
                    commercially sensitive position (whether or not such person
                    would commit any breach of his contract of employment or
                    engagement by reason of leaving the service of such company)
                    nor knowingly employ or aid or assist in or procure the
                    employment by any other person, firm or company of any such

                    other person in the habit of dealing with any of the Target
                    Group Companies to cease to deal with any of the Target
                    Group Companies either at all or in part or on the terms on
                    which he had previously dealt with any of the Target Group
                    Companies or likely to have the effect of causing any person
                    having a contract or arrangement with any of the Target
                    Group Company to breach, terminate or modify that contract
                    or arrangement;

                    likely to be confused with them;

             For the avoidance of doubt none of the foregoing restrictions shall
             prevent or any or all of Mr. Ian Suttie, Mr. David Suttie or Mrs.
             Suttie from a shareholder and/or director and/or employee of the
             Retained Group and/or B.S.W. Limited (Company Number 2894198)
             having its Registered at Engineering Building, Lancaster
             University, Bailrigg, Lancaster after provided that neither company
             acts in such a way as would constitute breach of the provisions of
             this Clause if it were bound by the terms hereof.

     12.2    Each undertaking and agreement contained in this Clause 12 shall be
             read and construed independently of the other undertakings and
             agreements herein contained and if any undertaking or agreement is
             held to be invalid whether as an unreasonable restraint of trade or
             for any other reason the remaining undertakings and agreements
             shall continue to apply to the extent that they shall not also be
             held to be invalid and the undertaking or agreement which is held
             to be invalid shall be referred by the parties to a Queen's Counsel
             (to be agreed by the parties) whose opinion shall be sought
   31

                                       29

             as to what restriction (not imposing any wider restrictions on the
             parties) would be legal and valid and the parties hereby agree that
             such undertaking or agreement shall be altered accordingly, the
             costs and expenses of the Queen's Counsel shall be borne equally by
             the parties hereto.


     12.3    Mr Ian Suttie, Mr. David Suttie and Mrs. Suttie by their execution
             hereof hereby agree that having regard inter alia to the price paid
             by the Purchaser for the Sale Shares the restrictions contained in
             this Clause are reasonable and necessary for the protection of the
             legitimate interests of the Purchaser and that having regard to
             those circumstances those covenants do not work harshly on them.

     12.4    Mr Ian Suttie, Mr. David Suttie and Mrs. Suttie hereby irrevocably
             consent to the Purchaser furnishing particulars of this Agreement
             to the UK Competition Authorities.

     13.1    The Majority Vendors hereby acknowledge and confirm that neither
             they nor the Retained Group Company have a claim on any account

             any of their Connected Persons.

     13.3    The Institutional Vendor hereby acknowledges and confirms that it
             does not have any claim against the Purchaser other than pursuant

             than the Fixed Dividend payable on the Preference Shares in terms
             of the Articles of Association of the

19. SECURITIES LAW MATTERS

     19.1    The Vendors recognise and understand that the Weatherford Shares
             will not, except as expressly provided in the Registration Rights
             Agreement, be registered under the U.S. Securities Act of 1933 (the
             "Securities Act") or under the securities laws of any other
             jurisdiction (the "Securities Laws"). The Weatherford Shares are
             not being so registered in reliance upon exemptions from the
             Securities Act and the Securities Laws which are predicated, in
             part, on the representations, warranties and agreements of the
             Vendors contained herein.

     19.2    Each of the Vendors severally represents and warrants that (i) the
             Vendor has business knowledge and experience, such experience being
             based on actual participation therein, (ii) the Vendor is capable
             of evaluating the merits and risks of an investment in the
             Weatherford Shares and the suitability thereof as an investment
             therefor and (iii) the Weatherford Shares to be acquired by the
             Vendors will be acquired solely for investment and not with a view
             toward resale or redistribution in violation of the Securities Act
             or the Securities Laws, it being acknowledged that the Vendors will
             have the right to resell the shares as provided in the Registration
             Rights Agreement or under the Securities Act and any resale or
             intended resale by them pursuant to the Registration Rights
             Agreement or under the Securities Act will not be a breach of this
             representation.

     19.3    The Vendors acknowledge that the certificates representing the
             Weatherford Shares will be imprinted with the following legend, the
             terms of which are specifically agreed to:

             THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
             INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
             1933, OR THE SECURITIES LAWS OF ANY JURISDICTION, IN RELIANCE UPON
             EXEMPTION FROM REGISTRATION REQUIREMENTS. WITHOUT SUCH
             REGISTRATION,

   36

                                       34

             SUCH SHARES MAY NOT BE SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE
             TRANSFERRED, EXCEPT UPON DELIVERY TO THE COMPANY OF AN OPINION OF
             COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT REGISTRATION IS
             NOT REQUIRED FOR SUCH SALE, PLEDGE, HYPOTHECATION OR TRANSFER OR
             THE SUBMISSION TO THE COMPANY OF SUCH OTHER EVIDENCE AS MAY BE
             SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH SALE, PLEDGE,
             HYPOTHECATION OR TRANSFER SHALL NOT BE IN VIOLATION OF THE
             SECURITIES ACT OF 1933 OR APPLICABLE STATE SECURITIES LAWS OR ANY
             RULE OR REGULATION PROMULGATED THEREUNDER.
             Each Vendor understands and acknowledges that appropriate stop
             transfer notations will be placed in the records of Weatherford and
             with its transfer agents in respect of the Weatherford Shares to be
             issued to the Vendors. Weatherford agrees that any Weatherford
             Shares sold pursuant to an effective registration statement,
             including a registration statement or the Shelf Registration filed
             pursuant to the Registration Rights Agreement or under the
             Securities Act, shall have the above legend removed to permit the
             closing of the sale within Three Business Days of written notice of
             the sale and certification by the Vendor that the sale was made
             pursuant to the plan of distribution described in the registration
             statement or the Shelf Registration and the prospectus delivery
             requirements under the Securities Act were fully complied with in
             connection with the sale.

           the Financial Services Act 1986.

           under Chapter I of Part XIV of the 1998 Act for the purposes of the
           PSO and there is no reason why such approval should be withdrawn. The
           Group Personal Pension Plan is approved under Chapter IV of Part XIV
           of the 1988 Act.

     3.3   A PSO letter of approval of the Pension Schemes is held by the
           trustees of the Pension Schemes and no event or transaction has taken
           place in relation to the Pension Schemes whose validity is dependent

           obtained.

     3.4   None of the Pension Schemes is contracted out of the state earnings
           related pension scheme although members of the Group Personal Pension
           Plan may elect to contract out on an individual basis.

     3.5   The Wellserv Scheme is closed and the costs of administration and
           winding up of this scheme are either paid from the assets of the
           scheme or are fully provided for in the Target Group's accounts. No
           Target Company has any outstanding, pending or future liability or
           commitment to make contributions or payments for expenses or costs
           relating to the Wellserv Scheme.

           the 1995 Act and in accordance with the schedule of contributions or
           payment schedule.

     4.3   There are no loans in existence from the Occupational Schemes to any
           Target Group Company or to any Member or beneficiaries of the
           Occupational Schemes or to any third party and as at the date of this
           Agreement none of the assets of the Occupational Schemes is an
           employer related investment within the meaning of section 40 of the
           1995 Act.

     4.4   Apart from lump sum benefits on death in service, benefits quantified
           by reference to a level of pay are not and have never been provided
           by or promised through the Pension Schemes.

     4.5   Each participating employer of the Pension Schemes and the Life
           Scheme has been party to a valid Deed of Adherence which has at all
           times been complied with in all material respects and its
           participation in the Pension Schemes and the Life Scheme has been
           approved by the PSO.

5.   EXERCISE OF DISCRETION

     5.1   Apart from as disclosed none of the Target Group, the Warrantor or
           the Pension Schemes' or Life Scheme's trustees have given
           undertakings or assurances to the Members beneficiaries under the
           Pension Schemes or Life Scheme or Employees as to the introduction,
           continuance, increase or improvement of any retirement, death or
           disability benefits or as to the announcement of any benefit on the
           happening of a given set of circumstances.

     5.2   No discretion has been exercised under the Pension Schemes or Life
           Scheme to provide a benefit which would not otherwise already be
           provided for under the Pension Schemes or Life Scheme, to waive any
           standard eligibility conditions, to augment or provide new benefits
           or to refuse admission to an
   91

                                       89


           Employee or director who would otherwise be eligible to join the
           Pension Schemes or Life Scheme or to alter the payment of expenses or
           contributions by any Target Group Company.

     5.3   Neither employees of the Target Group who have been made redundant
           nor officers of the Target Group who have been removed from office
           are, or have been, routinely treated more favourably under the
           Pension Schemes than other members.

6.   DEATH BENEFITS

     6.1   Any benefits payable on the death of a Member whilst in employment
           (other than a return of Member's own contributions) or during a
           period of sickness or disability are fully insured, all premiums due
           to the insurance company have been paid and each Member or other
           beneficiary has been covered for such benefits by an insurance
           company of repute at normal rates and on normal terms for persons in
           good health. So far as the Warrantor is aware, having made enquiry of
           the trustees or administrators of the Pension or Life Schemes,
           nothing has been done or left undone which might entitle the
           insurance company to avoid or limit its liability under any contract
           covering these benefits. The Warrantor has given the Purchaser full
           details of the current premiums for this insurance, and copies of the
           insurance contracts.

7.   DISCRIMINATION

     7.1   The Pension Schemes and the Life Scheme do not and have never been
           operated in such a way as to directly or indirectly discriminate
           between:-


           7.1.1 male and female Employees as regards eligibility, the rates of
                 contribution and the amounts of any benefits provided or the
                 dates on or from which the benefits are to be or may be
                 provided in any way which is contrary to Article 141 of the
                 Treaty of Rome or any corresponding domestic legislation;

           7.1.2 all other Employees in any other unlawful discriminatory manner
                 as regards eligibility, rates of contributions and the amounts
                 of
   92

                                       90

           any benefits provided or the dates on or from which the benefits are
           to be or may be provided.

8.   EXTERNAL ADVISERS

     8.1   All consulting, actuarial, trusteeship and other fees, charges and
           expenses of whatever nature with respect to the Pension Schemes and
           Life Scheme have been paid and no services have been rendered for
           which an account or invoice has not been delivered to and paid by the
           Target Group. All costs, charges and expenses are met from the assets
           of the Pension Schemes and Life Scheme.

           threatened by any of the Members, beneficiaries of the Pension
           Schemes or Life Scheme or Employees and there are no facts or
           circumstances likely to give rise to any such proceedings.

           occupation of the UK Properties and there are no circumstances of

           continuing vacant and undisputed possession or occupation of the UK
           Properties by Target Group.

                  indication that, and the Warrantors, having made all
                  reasonable enquiries, know of no reason why, any such review,
                  audit or investigation or enquiry is to be or may be
                  initiated by any Taxation Authority.

     such Claim (in the absence of settlement or discharge of such claim) have

                                      127

6.   The Warrantor shall not be liable for any breach of the Tax Warranties

     reasonable estimate of the aggregate liability of the Warrantor in respect
     of such claim as are known at the time) has been notified in writing to the
     Warrantor before the seventh anniversary of Completion and legal
     proceedings in respect of such Claim (in the absence of settlement or
     discharge of such claim) have commenced within six months after such
     written notice is first served on the Warrantor or within six months of the
     liability the subject of the claim becoming actual rather than contingent
     (if later).

7.   The Warrantor shall not be liable for any Claim (other than a Claim under
     the Tax Deed) to the extent that any liability is increased or arises from:

     7.1   the enactment of or coming into force after the date of this
           Agreement of any legislation not enacted or not in force at the date
           of this Agreement;

     7.2   any amendment to any legislation which is enacted or comes into force
           after the date of this Agreement;

     7.3   any change in interpretation of any law or any change in

           agency or regulatory body announced after the date of this Agreement;

8    The Warrantor shall not be liable for any Claim (other than a Claim under
     the Tax Deed) in respect of any matter or liability to the extent that an
     express and specific provision (including, for the avoidance of doubt,
     express and specific for matters contained in any deferred taxation
     provision and any obsolete stock provision), accrual, reserve or note in
     respect thereof was made in the Accounts.

9.   The Warrantor shall not be liable for any Claim (other than a Claim under
     the Tax
   130

                                      128


     Deed) which would not have arisen but for a voluntary act or failure to
     act, omission or transaction on the part of the Purchaser and/or (at the
     instance of the Purchaser) by any Target Group Company occurring after
     Completion otherwise than in the ordinary course of the Business and which
     the Purchaser was aware would or would be likely to give rise to a Claim.

10.  The Warrantors shall have no liability in respect of any Claim (other than
     a Claim under the Tax Deed):

     10.1  where the liability is contingent only, unless and until such
           liability becomes an actual liability and becomes due and payable; or

     10.2  which arises by virtue of any revaluation of property or assets owned
           by any Target Group Company after the Completion Date; or

     10.3  in respect of any matter fairly disclosed in the Disclosure Letter;
           or

     10.4  to the extent that the subject matter of such claim is covered by a
           policy of insurance in force on the date of this Agreement and
           payment is made by the insurer under such policy or under a similar
           policy effected by the Purchaser or any Target Group Company; or
           subject to the matter being an insurance risk, would have been so
           covered had such policy of insurance been maintained beyond the date
           of this Agreement, and the Purchaser shall procure that all
           appropriate claims under such insurance are duly and timeously made
           and prosecuted in good faith.

11.  Nothing in this Agreement shall restrict any general obligation at law of
     the Purchaser to mitigate any loss or damage which it may suffer in
     consequence of any breach by the Warrantor of the Warranties or the
     Indemnities and shall take all reasonable steps (and so far as within its
     power shall procure that such steps are taken) to mitigate any loss or
     liability which might give rise to a claim against the Warrantors under the
     Warranties and/or the Indemnities and, without prejudice to the foregoing
     generality, procure that all reasonable endeavours are used to recover any
     amounts due from third parties where (without being required to initiate
     legal proceedings for recovery), in relation to any matter which may give
     rise to a claim under the Warranties and/or
   131

                                      129


     the Indemnities, the Purchaser or any Target Group Company has or may have
     a claim against such third parties.

12.  If the Warrantor pays to the Purchaser an amount in discharge of a Claim
     (other than a Claim under the Tax Deed) and the Purchaser subsequently
     recovers (whether by payment, discount, credit, relief or otherwise) from a
     third party a sum which is referable to the matter giving rise to the Claim
     or obtains a relief which is so referable, the Purchaser shall forthwith
     repay to the Warrantors:-

     (a)   an amount equal to the sum recovered from the third party (or the
           value of the relief obtained, calculated by reference to the amount
           saved) less any reasonable out-of-pocket costs and expenses incurred
           by the Purchaser in recovering the same and less any tax suffered on
           the receipt; or

     (b)   if the figure resulting under paragraph (a) above is greater than the
           amount paid by the Warrantors to the Purchaser in respect of the
           relevant claim, such lesser amount as shall have been so paid by the
           Warrantors.

13.  The Purchaser agrees with the Warrantor that it shall not be entitled to
     recover damages from the Warrantor or to recover under any indemnity from
     the Warrantor more than once in respect of the same loss and payment of any
     Claim under any provision of this Agreement or the Tax Deed shall pro tanto
     satisfy and discharge any other claim which is capable of being made in
     respect of the same subject matter.

15.  A breach of Warranty which is capable of remedy shall not entitle the
     Purchaser to compensation unless the Warrantors are given written notice of
     such breach and such breach is not then remedied (without any cost or
     liability to the Purchaser) within 20 Business Days (or such longer or
     shorter period as shall in all the circumstances be reasonable) after the
     date on which such notice is served on the Warrantors.

16.  If any Claim (other than a Claim under the Tax Deed) shall arise by reason
     of some liability which at the time that the claim is notified to the
     Warrantors is contingent only, the Warrantors shall not be under any
     obligation to make any payment to the Purchaser in respect of such claim
     until such time as the contingent liability ceases to be so contingent,
     provided always that this sub-clause shall not operate to avoid a

   132

                                      130

     claim made in respect of a contingent liability within the time limits
     specified in paragraphs 1.1.5 or 1.1.6 above (notwithstanding that no
     proceedings are taken in respect thereof within the time limit specified in
     paragraph 1.1.13 above); provided that once the liability in question
     becomes actual then the Purchaser shall be bound to issue and serve legal
     proceedings on the Warrantor within the following six month period.

17.  The Warrantors shall not be liable to pay any sum in respect of the same
     matter under both the Warranties and the Tax Deed, and the Purchaser shall
     not be entitled to make double recovery in respect of the same matter under
     different Warranties or under different parts of the same Warranty.

Dear Sirs

ACQUISITION BY WEATHERFORD UK LIMITED OF THE ENTIRE ISSUED SHARE CAPITAL OF
ORWELL GROUP PLC ("THE ACQUISITION")

We refer to the Sale and Purchase Agreement entered into by (1) Weatherford UK
Limited, (2) 3i Group plc, (3) Ian Alexander Suttie and others (therein together
called the "Majority Vendors") and (4) Weatherford International Inc. and dated
24th February 2001 (the "Agreement"). Words and expressions defined in the
Agreement shall have the same meaning in this letter.

We also refer to the notice dated 10th April 2001 served by us in our capacity
as the Purchaser on 11th April 2001 giving the Majority Vendors and
Institutional Vendor notice that the Purchaser had discovered a Material Adverse
Effect of the Target Group and, in accordance with the provisions of Clause 2.4
of the Agreement to terminate the Agreement with effect from the date of service
thereof (the "Notice").

Notwithstanding the foregoing, it is hereby agreed by all of the parties to the
Agreement as follows:

(1)  that the Notice shall be treated as if it had not ever been served and that
     the Agreement shall continue to have full force and effect in accordance
     with its terms subject to the amendments made in this letter agreement;

(2)  the Completion Date for the Acquisition will be Thursday 19th April 2001 or
     such other date as the parties agree in writing;

(3)  the Consideration for the Acquisition will be that number of whole shares
     of Weatherford Common Stock which at a price per share of Fair Market Value
     as are equal in value to the sum of One hundred and eighty two million one
     hundred and fifty five thousand Pounds Sterling ((pound)182,155,000) less
     the Indebtedness as certified in the Indebtedness Statement rather than the
     number of shares calculated in accordance with the definition of
     Consideration stated in the Agreement;

(4)  stock certificates for a number of whole shares of Weatherford Common Stock
     to be issued to Mr Ian Suttie as part of the Consideration as noted in (3)
     above having a Fair Market Value of Ten


   151
                                       3


     million Pounds Sterling ((pound)10,000,000) ("the Retained Shares") will be
     retained by the Purchaser's Solicitors for a period of one year ("the
     Retention Period") from the Completion Date by way of security in respect
     of any actual or alleged breach of the Warranties, or the Tax Deed or any
     claims under the Indemnities, provided always:

     (a)  the shares represented by those stock certificates will be issued in
          the name of Mr Ian Suttie and will be registered in terms of the
          Registration Rights Agreement;

     (b)  Mr Ian Suttie may at any time during the Retention Period, elect to
          sell all or any of the Retention Shares by submitting written notice
          to that effect to the Purchaser's Solicitors ("Retention Period Share
          Sale");

     (c)  the proceeds of any Retention Period Share Sale shall be dealt with as
          follows:

          (i)  a cash sum equal to the Fair Market Value of each Retained Share
               sold in terms of paragraph 4(b) above, shall be paid into an
               interest bearing deposit account to be opened in the joint names
               of Mr Ian Suttie and the Purchaser with The Royal Bank of
               Scotland plc ("Joint Account") and such cash amount shall be held
               in that account for the unexpired portion of the Retention
               Period; and

          (ii) the amount (if any) in excess of the Fair Market Value of each
               Retained Share sold in terms of paragraph 4(b) above shall be
               paid over to Mr Ian Suttie or as he lawfully directs;

     (d)  unless the Purchaser has served notice of a claim for an alleged
          breach of the Warranties or a claim under the Indemnities or the Tax
          Deed prior to the expiry of the Retention Period ("Release Date") and
          such Claim has not been satisfied, settled or withdrawn prior to the
          Release Date, the Purchaser's Solicitors shall deliver to Mr Ian
          Suttie on the Release Date the stock certificates then held by them in
          respect of Retention Shares and/or the Purchaser shall execute all
          documents necessary to allow Mr Ian Suttie to uplift the funds held in
          any Joint Account; and

     (e)  If the Purchaser has served notice of a claim for an alleged breach of
          the Warranties or a claim under the Indemnities or the Tax Deed prior
          to the Release Date and such claim has not been satisfied, settled or
          withdrawn prior to the Release Date, the Purchaser's Solicitors shall
          be entitled to continue to retain
   152
                                       4


          such number of Retention Shares and such amount of cash shall continue
          to be held in such Joint Account which in aggregate is equal to a
          reasonable estimate of the liability of Mr Ian Suttie in respect of
          such claim until such claim is satisfied settled or withdrawn and the
          excess amount of Retained Shares and/or cash will be delivered or paid
          over to Mr Ian Suttie (as the case may be).

(5)  the specific matters noted in the Schedule to the Notice (other than those
     noted in the Schedule to this letter), shall not form the basis of a claim
     for breach of the Warranties, or under the Indemnities or the Tax Deed;

(6)  Indebtedness for the purposes of the Agreement shall be deemed to include
     and shall therefore be increased by the total amount of the Outstanding
     Payables which, for the purposes of this letter of agreement and the
     Agreement shall be defined as:

     (a)  all cheques which have been drawn by the Target Group but which have
          not been presented or which remain uncleared at the Completion Date;

     (b)  all telegraphic or electronic transfers of funds which have been
          instructed by the Target Group but remain incomplete at the Completion
          Date of the Acquisition; and

     (c)  all trade creditors accounts of the Target Group at the Completion
          Date, to the extent that the same have been outstanding for a period
          of 75 days or more from the date of the relevant invoice.

     Provided always that, on or before the Completion Date, the parties shall
     agree an estimate of the Outstanding Payables (hereinafter called the
     "Estimated Outstanding Payables") which shall be deemed to be Indebtedness
     and will be included in the Indebtedness Statement for the purposes of
     calculating the Consideration payable at Completion.

     The parties hereby agree that, as soon as possible after the Completion
     Date and no later than 20 Business Days after the Completion Date the
     Purchaser will determine the actual amount of the Outstanding Payables.

     In the event that the Outstanding Payables exceed the Estimated Outstanding
     Payables, the Majority Vendors agree to transfer to the Purchaser, within
     ten Business Days of the determination of the Outstanding Payables, such
     number of Weatherford Shares, at a price per share of Fair Market Value,
     issued to them as part of the Consideration as is equal in value to the
     amount by which the
   153
                                       5


     Outstanding Payables exceed the Estimated Outstanding Payables. Upon such
     transfer, any warranty by Mr Ian Suttie in relation to the Indebtedness
     Statement, to the extent that it relates to the amount of Outstanding
     Payables, shall be discharged pro tanto.

     In the event that the Estimated Outstanding Payables exceed the Outstanding
     Payables, the Purchaser agrees to issue to the Majority Vendors (on the
     same basis as in Clause 4.4.3 of the Agreement) within ten Business Days of
     the determination of the Outstanding Payables, such number of Weatherford
     Shares, at a price per share of Fair Market Value, as additional
     consideration as is equal in value to the amount by which the Estimated
     Outstanding Payables exceed the Outstanding Payables.

(7)  In relation to the Indebtedness Statement, the Purchaser acknowledges and
     agrees that the basis of calculation of those items under the heading "HP
     Commitments" shall be the relevant settlement figures for discharge of each
     of the contracts or agreements to which the Target Group Companies are
     party as at close of business on 18 April. In the event that the aggregate
     amount of such settlement figures is greater or less than the amounts shown
     under the said heading in the Indebtedness Statement then

     (a)  the amount of any excess shall be the subject of the indemnity
          provided in Clause 18.1.2 of the Agreement but any recovery competent
          to the Purchaser shall be satisfied by Mr Ian Suttie by the transfer
          by Mr. Ian Suttie to the Purchaser, within ten Business Days of the
          determination of the said aggregate amount of such settlement figures,
          of such number of Weatherford Shares, at a price per share of Fair
          Market Value, issued to him as part of the Consideration as is equal
          in value to the amount of such excess or, at the option of and to the
          extent required by the Purchaser by setting off the amount of such
          excess against any obligation of the Purchaser in relation to the
          payment of Additional Consideration to Mr. Ian Suttie in terms of
          Clause 4.4.3 of the Agreement without prejudice to the entitlement of
          the other Vendors to such Additional Consideration and, if such excess
          is greater than the amount of Additional Consideration attributable to
          Mr. Ian Suttie, then additionally against the obligation of the
          Purchaser in relation to that part of the amount by which the
          Estimated Outstanding Payables exceed the Outstanding Payables
          attributable to Mr. Ian Suttie's proportionate part of the entitlement
          of the Majority Vendors under the final paragraph of (6) above; and

     (b)  the amount of any deficiency shall be satisfied by the Purchaser by
          the issue to Mr. Ian Suttie within ten Business Days of the

   154
                                       6


          determination of such deficiency of such number of Weatherford Shares
          at a price per share of Fair Market Value as additional consideration
          as is equal in value to the amount of such deficiency.

(8)  Indebtedness for the purposes of the Agreement shall be reduced by the sum
     of One million two hundred and eighty eight thousand Pounds Sterling
     ((pound)1,288,000) being the sum payable to Target by a company controlled
     by Mr Ian Suttie in consideration for the sale and purchase of the shares
     held by Target in First Oil plc. A bankers draft for such amount will be
     delivered to Target on the Completion Date.

For the avoidance of doubt the Purchaser accepts (subject to the Purchaser
confirming in writing that it is fully satisfied that the relevant liabilities
have been fully and finally discharged by the Target Group) that the matters
covered by the specific indemnities set out at Clauses 18.1.7 paragraphs (a),
(b), (c) and (d) (claims by Smith International (North Sea) Limited) have been
settled and that the said indemnities will be of no further effect and no claim
shall lie against Mr Ian Suttie in respect thereof.

It is agreed that the terms of this letter shall be binding upon the parties to
the Agreement with effect from the date hereof.

For the avoidance of doubt, the remaining provisions of the Agreement shall as
amended by this letter continue to have full force and effect.
