         (b) such security or indemnity that may be reasonably required by the
         Indenture Trustee or its agent to hold the Indenture Trustee and its
         agent harmless with respect to any such representation of such holder.
         Upon compliance with the preceding sentence, such holder shall, for all
         purposes under the Plan, be deemed to have surrendered such instrument.
         Weatherford shall be deemed to have surrendered such instrument as a
         capital contribution to Dailey International. Any holder of a Senior
         Note which has not surrendered or been deemed to have surrendered its
         Senior Notes within two years after the Effective Date shall have its
         Claim as a holder of Senior Notes disallowed, shall receive no
         distribution on account of its Claim as a holder of Senior Notes, and
         shall be forever barred from asserting any Claim on account of its
         Senior Notes. Any Weatherford - Senior Note Holder Consideration issued
         and held for distribution on account of such disallowed claims of
         holders of Senior Notes shall be returned to Weatherford. As of the
         Effective Date, all Senior Notes shall represent only the right to
         participate in the distributions provided in the Plan on account of
         such Senior Notes.

                  b. SURRENDER OF OLD COMMON STOCK. As a condition to receiving
         the Weatherford Old DII Equity Consideration distributable under the
         Plan, the holders of Old Common Stock shall surrender their Old Common
         Stock to the Disbursing Agent. Any holder of Old Common Stock whose
         instrument has been lost, stolen, mutilated or destroyed shall, in lieu
         of surrendering such instrument, deliver to the Disbursing Agent: (a)
         evidence satisfactory to the Disbursing Agent of the loss, theft,
         mutilation or destruction of such instrument, and (b) such security or
         indemnity that may be reasonably required by the Disbursing Agent to
         hold the Disbursing Agent harmless with respect to any such
         representation of such holder. Upon compliance with the preceding
         sentence, such holder shall, for all purposes under the Plan, be deemed
         to have surrendered such instrument. Any holder of Old Common Stock
         that has not surrendered or been deemed to have surrendered its Old
         Common Stock within two years after

   35


         the Effective Date shall have its Interest as a holder of Old Common
         Stock disallowed, shall receive no distribution on account of its
         Interest as a holder of Old Common Stock, and shall be forever barred
         from asserting any Claim or Interest on account of its Old Common
         Stock. Any Weatherford - Old DII Equity Consideration issued and held
         for distribution on account of such disallowed Interests of holders of
         Old Common Stock shall be returned to Weatherford. As of the Effective
         Date, all Old Common Stock shall represent only the right to
         participate in the distributions provided in the Plan on account of
         such Old Common Stock.

                  c. SURRENDER OF CLASS 7 INTERESTS. On the Effective Date, the
         instruments evidencing the Interests of holders of Interests in Class 7
         shall be deemed surrendered and canceled. All rights of such holders
         attributable to their Class 7 Interests shall be forever terminated and
         extinguished as of the Effective Date.

         7.4 BALLOT RECORD DATE; DISTRIBUTION DATE. The Indenture Trustee shall
distribute all Weatherford - Senior Note Holder Consideration to be distributed
pursuant to the Plan to the record holders of Senior Notes, other than
Weatherford, as of the Ballot Record Date, unless, prior to the Effective Date,
the holder or transferee of any such Claim furnishes the Indenture Trustee, or
its agent, with sufficient evidence (in the Indenture Trustee's or its agent's
sole and absolute discretion) of the transfer of such Claim, in which event the
Indenture Trustee shall distribute, or cause to be distributed, all
distributions of property to the transferee of such Claim as of the Effective
Date. As of the close of business on the Effective Date, the transfer ledgers
with respect to the Senior Notes shall be closed and the Debtors, the
Reorganized Debtors, and the Indenture Trustee shall have no obligation to
recognize any transfer of the Senior Notes occurring thereafter.

         The Disbursing Agent shall distribute all Weatherford - Old DII Equity
Consideration to be distributed pursuant to the Plan to the record holders of
Old Common Stock as of the Ballot Record Date, unless, prior to the Effective
Date, the holder or transferee of any such Interest furnishes the Disbursing
Agent with sufficient evidence (in the Disbursing Agent's sole and absolute
discretion) of the transfer of such Interest, in which event the Disbursing
Agent shall distribute, or cause to be distributed, all distributions of
property to the transferee of such Interest as of the Effective Date. As of the
close of business on the Effective Date, the transfer ledgers with respect to
the Old Common Stock shall be closed and the Debtors and the Reorganized Debtors
shall have no obligation to recognize any transfer of the Old Common Stock
occurring thereafter.

         7.5 DISPUTED CLAIMS. Notwithstanding any other provisions of the Plan,
no payments or distributions shall be made on account of any Disputed Claim
until such Claim becomes an Allowed Claim, and then only to the extent that it
becomes an Allowed Claim.

         7.6 MANNER OF PAYMENT UNDER THE PLAN. Cash payments made by the
Reorganized Debtors pursuant to the Plan shall be in U.S. dollars by checks
drawn on a domestic bank selected by the Reorganized Debtors or by wire transfer
from a domestic bank, at the Reorganized Debtor's option, except that payments
made to foreign trade creditors holding Allowed Claims may be paid, at the
option of the Reorganized Debtors, in such funds and by such means as are
necessary or customary in a particular foreign jurisdiction.

         7.7      DELIVERY OF DISTRIBUTIONS AND UNDELIVERABLE OR UNCLAIMED
                  DISTRIBUTIONS.

                  a.       DELIVERY OF DISTRIBUTIONS IN GENERAL. Except as
                  provided below in section 7.7(b) for holders of undeliverable
                  distributions, distributions to holders of Allowed Claims
                  shall be distributed by mail as follows: (a) except in the
                  case of the holder of a Senior Note, (1) to the addresses set
                  forth on the respective proofs of claim filed by such holders;
                  (2) to the addresses set forth in any written notices of
                  address changes delivered to the Reorganized Debtors after the
                  date of any related proof of claim; or (3) to the addresses
                  reflected on the Schedules of Assets and Liabilities Filed by
                  the Debtors if no proof of Claim or proof of Interest is Filed
                  and the Reorganized Debtors have not received a written notice
                  of a change of address; and (b) in the case of the holder of a
                  Senior Note, by the Indenture Trustee to the latest mailing
                  address maintained of record by the pertinent Indenture
                  Trustee.

                  b.       UNDELIVERABLE DISTRIBUTIONS.

                           i. HOLDING AND INVESTMENT OF UNDELIVERABLE PROPERTY.
                           If the distribution to the holder of any Claim or
                           Interest other than the holder of a Senior Note is
                           returned to the Reorganized Debtors or the Disbursing
                           Agent as undeliverable, no further distribution shall
                           be made to such holder unless and until the
                           Reorganized Debtors or the Disbursing Agent are
                           notified in writing of such holder's then current
                           address. Subject to section 7.7(b)(ii), undeliverable
                           distributions shall remain in the possession of the
                           Reorganized Debtors or the Disbursing Agent pursuant
                           to this section until such time as a distribution
                           becomes deliverable.

                           Unclaimed Cash (including interest, dividends and
                           other consideration, if any, distributed on or
                           received for undeliverable Weatherford Common Stock)
                           shall be held in trust in a segregated bank account
                           in the name of Reorganized Dailey International, for
                           the benefit of the potential claimants of such funds,
                           and shall be accounted for separately. Such funds
                           shall be held in interest-bearing accounts if
                           practicable, and the parties entitled to such funds
                           shall be entitled to their Pro Rata share of any
                           interest earned on such funds.

                           Undeliverable Weatherford - Old DII Equity
                           Consideration shall be held in trust for the benefit
                           of the potential claimants of such consideration. The
                           Disbursing Agent shall hold in trust a number of
                           shares sufficient to provide for unclaimed amounts of
                           such securities.

                           ii. DISTRIBUTION OF UNDELIVERABLE PROPERTY AFTER IT
                           BECOMES DELIVERABLE AND FAILURE TO CLAIM
                           UNDELIVERABLE PROPERTY. Any holder of an Allowed
                           Claim or Interest other than a holder of a Senior
                           Note who is entitled to but does not assert a claim
                           for an undeliverable distribution held by the
                           Reorganized Debtors, or the Disbursing Agent, within
                           two (2) years after the Effective Date shall no
                           longer have any claim to or interest in such
                           undeliverable distribution, and shall be forever
                           barred from receiving any distributions under this
                           Plan. In such cases, any Cash held for distribution
                           on account of such Claims shall be

DEBTORS' JOINT PLAN OF REORGANIZATION                                    Page 28

   37


                           delivered to the Reorganized Debtors, and any
                           undeliverable Weatherford - Old DII Equity
                           Consideration shall be returned to Weatherford.

                  c. FAILURE TO PRESENT CHECKS. Checks issued in respect of
                  distributions under the Plan shall be null and void if not
                  presented for payment by the drawee bank within 60 days after
                  the date of issuance. Any amounts returned to the Reorganized
                  Debtors in respect of such checks shall be held by the
                  Reorganized Debtors. Requests for re-issuance of any such
                  check may be made directly to the Reorganized Debtors by the
                  holder of the Allowed Claim with respect to which such check
                  originally was issued, in which case a replacement check in
                  the same amount as the original, unpresented check shall be
                  issued. Any claim in respect of such voided check is required
                  to be made before the second anniversary of the Effective
                  Date, after which time all Claims in respect of void checks
                  and the underlying distributions shall be discharged and
                  forever barred from assertion against the Reorganized Debtors
                  and their property.

         7.8 COMPLIANCE WITH TAX REQUIREMENTS. In connection with the Plan, to
the extent applicable, the Reorganized Debtors shall comply with all withholding
and reporting requirements imposed on them by any governmental unit, and all
distributions pursuant to the Plan shall be subject to such withholding and
reporting requirements. The Weatherford - Senior Note Holder consideration will
be allocated first to principal and then, to the extent such consideration
exceeds the principal amount of the Claim, to accrued but unpaid interest.

         7.9 SETOFFS. Unless otherwise provided in a Final Order or in this
Plan, the Debtors may, but shall not be required to, offset against any Claim
and the payments to be made pursuant to the Plan in respect of such Claim, any
claims of any nature whatsoever the Debtors may have against the holder of such
Claim or its predecessor, but neither the failure to do so nor the allowance of
any Claim hereunder shall constitute a waiver or release by the Debtor of any
such claims the Companies may have against such holder or its predecessor.

         7.10 FRACTIONAL INTERESTS. The calculation of any percentage
distribution of Weatherford Common Stock to be made to holders of certain
Allowed Claims and Interests as provided elsewhere in this Plan may
mathematically entitle the holder of such an Allowed Claim or Interest to a
fractional interest in such Weatherford Common Stock. For purposes of applying
this section, the holders of Allowed Claims or Interests under or evidenced by
Old Securities shall, in the case of Old Securities held in street name, mean
the beneficial holders thereof as of the Effective Date.

         In lieu of fractional shares of Weatherford Common Stock, a Person who
would otherwise be entitled to receive a fraction of a share shall receive Cash,
without interest, in an amount equal to such fraction multiplied by the Fair
Market Value of the Weatherford Common Stock. The total number of shares of
Weatherford Common Stock to be distributed to a class of Claims or Interests
shall be adjusted as necessary to account for such elimination of fractional
shares.

                                  ARTICLE VIII

              TREATMENT OF EXECUTORY CONTRACTS AND UNEXPIRED LEASES

         8.1 ASSUMPTION OF ALL EXECUTORY CONTRACTS AND LEASES NOT REJECTED. The
Plan constitutes and incorporates a motion by the Debtors to assume, as of the
Effective Date, all pre-petition executory contracts and unexpired leases to
which the Debtors are a party (including the Acquisition Agreement, the
Technology Agreement and the Lawrence Leases, as modified by the Lawrence/Dailey
Lease Modification Agreements), except for any executory contract or unexpired
lease that (a) has been previously assumed or rejected pursuant to a Final
Order, (b) is the subject of a pending contested motion for authority to assume
the contract or lease Filed by the Debtors prior to the Confirmation Date, or
(c) is identified on the Plan Supplement. The Plan Supplement shall be filed on
or before ten (10) days prior to the hearing to consider Confirmation of this
Plan and will include a list of all executory contracts or unexpired leases that
the Debtors intend to reject pursuant to the Plan (together, the "Rejected
Contracts"). Each assumed executory contract or assumed unexpired lease
(together, the "Assumed Contracts") shall, pursuant to the Plan, be assumed
without further order of Court upon Confirmation of this Plan. Each Rejected
Contract shall, pursuant to the Plan, be rejected without further order of the
Court upon Confirmation of this Plan.

         8.2 CURE PAYMENTS. Any Cure Payment for each Assumed Contract shall be
made (i) in Cash on the Effective Date, or (ii) on such other terms as agreed to
by the Reorganized Debtors and the non- debtor parties to such Assumed Contract.
In the event of a dispute regarding (i) the amount of any Cure Payment, (ii) the
ability of the Reorganized Debtors to provide adequate assurance of future
performance under the Assumed Contract, or (iii) any other matter pertaining to
assumption (or assumption and assignment), the Cure Payment required by section
365(b)(1) of the Bankruptcy Code shall be made by the Reorganized Debtors
following the entry of a Final Order resolving the dispute and approving such
assumption.

         8.3 BAR DATE FOR FILING OF REJECTION CLAIMS. Any Rejection Claim
arising from the rejection under this Plan of a Rejected Contract must be Filed
within thirty (30) days after the mailing of notice of Confirmation. Any
Rejection Claim that is not filed within such time frame shall be forever barred
and unenforceable against the Debtors, the Estates, the Reorganized Debtors, any
of their affiliates, successors and assignees, and their properties and barred
from receiving any distribution under this Plan. Any Allowed Rejection Claim
shall be treated in this Plan as a general unsecured Claim against the Debtor
that is a party to the Rejected Contract.

         8.4 CHANGE IN CONTROL CONTRACTS. On the Effective Date, all Change in
Control Contracts will be deemed rejected. Any non-Debtor party to a rejected
Change in Control Contract will have an allowed Rejection Claim in Class 4A,
pursuant to section 502(b)(7) of the Bankruptcy Code, equal to the compensation
provided by such party's employment agreement, without acceleration, for one
year following the Petition Date plus any unpaid compensation, without
acceleration, as of the Petition Date. All non-Debtor parties to rejected Change
in Control Contracts, except James D. Lawrence, will enter into consulting
contracts with Reorganized Dailey International on the Effective Date. Each such
consulting contract shall have a term of one year and provide for compensation
payable to the non-Debtor party equal to the difference between the payment in
respect of that party's Rejection Claim and the aggregate amount which would
have been payable if a change of control severance payment had been due
immediately prior to the commencement of the Reorganization Case. James D.
Lawrence will

   39


receive a bonus from Reorganized Dailey International on the Effective Date
equal to the difference between the payment he receives on account of his
Rejection Claim and the aggregate amount of severance that would have been
payable to him if a change of control severance payment had been due immediately
prior to the commencement of the Reorganization Case.


                                   ARTICLE IX

                         MODIFICATION OF LAWRENCE LEASES

         9.1 ASSUMPTION OF LAWRENCE LEASES. Notwithstanding Article VIII of the
Plan, the Plan constitutes and incorporates a motion by Dailey International to

the Bankruptcy Code in accordance with the terms of this Article IX. Subject to
the terms of this Article IX and conditioned upon the execution of the

         10.2 CANCELLATION OF OLD SECURITIES. On the Effective Date, all Old
Securities shall be terminated and canceled, and the indentures or statements of
resolution governing such Old Securities shall be rendered void. Notwithstanding
the foregoing, such termination will not impair the rights and duties under the
Indenture between the Indenture Trustee and the beneficiaries of the trust
created thereby including, but not limited to, the rights of the Indenture
Trustee to receive payment of its fees and expenses, to the extent not paid by
Reorganized Dailey International, from amounts distributable to holders of the
Senior Notes.

         10.7 REMOVAL OF OFFICERS AND DIRECTORS. On the Effective Date, the

                          EFFECTS OF PLAN CONFIRMATION

         12.1 DISCHARGE OF DEBTORS AND REORGANIZED DEBTORS AND INJUNCTION. The
rights afforded in this Plan, including the issuance by Weatherford of
Weatherford Common Stock to the holders of Claims or Interests, and the
treatment of all Claims and Interests herein, shall be in exchange for and in
reliance on the complete satisfaction, discharge, and release of all Claims and
Interests of any nature whatsoever, including any interest accrued on such

or any of their assets or properties. Except as otherwise provided in this Plan
or the Confirmation Order: (i) on the Effective Date, the Debtors, the
Reorganized Debtors, and all of their affiliates, shall be deemed discharged and
released to the fullest extent permitted by section 1141 of the Bankruptcy Code
from all Claims and Interests, including, but not limited to, demands,
liabilities, Claims and Interests that arose before the Effective Date and all

Effective Date the Confirmation Order shall act as a discharge of any and all
Claims against and all debts and liabilities of the Debtors or the Reorganized
Debtors, as provided in sections 524 and 1141 of the Bankruptcy Code, and such
discharge shall void any judgment against any of the Debtors or the Reorganized
Debtors and their affiliates at any time obtained to the extent that it relates
to a discharged Claim.

         Except as otherwise provided in this Plan or the Confirmation Order, on
and after the Effective Date, all persons who have held, currently hold or may

any kind against any obligation due to the Debtors, the Reorganized Debtors, any
of their affiliates, successors or assignees, or their respective properties;
and (v) commencing or continuing any action, in any manner, in any place that
does not comply with or is inconsistent with the provisions of this Plan or the

injunction shall recover actual damages, including costs and attorneys' fees,
and, in appropriate circumstances, may recover punitive damages, from the
willful violator.

         12.2 REVESTING. On the Effective Date, the Reorganized Debtors will be
vested with all the property of the respective Estates of the Debtors free and
clear of all Claims and other interests of creditors and equity holders, except
as provided herein; provided, however, that the Debtors shall continue as
debtors-in-possession under the Bankruptcy Code until the Effective Date, and,
thereafter, the Reorganized Debtors may operate their businesses free of any
restrictions imposed by the Bankruptcy Code or the Court.

         12.3 NO LIABILITY FOR SOLICITATION OR PARTICIPATION. As specified in
section 1125(e) of the Bankruptcy Code, the Confirmation Order shall provide
that Persons who have solicited acceptances or rejections of the Plan and/or
participated in the offer, issuance, sale, or purchase of securities offered or
sold under the Plan, have acted in good faith and in compliance with the
applicable provisions of the Bankruptcy Code, and are not liable on account of

         12.4 LIMITATION OF LIABILITY. None of the Debtors, the Reorganized
Debtors, Weatherford, the Creditors' Committee and its members, the Indenture
Trustee, or the Senior Note Holders who entered into the voting agreement with
the Debtor dated May 21, 1999, any of their affiliates nor any of their
respective officers, directors, employees, members or agents, nor any
professional Persons employed by any of them (collectively, the "Exculpated
Persons"), shall have or incur any liability to any Person for any act taken or
omission made in good faith in connection with or related to negotiating,
formulating, implementing, confirming or consummating the Plan, the Disclosure
Statement, the Acquisition Agreement or any contract, instrument, release or
other agreement or document created in connection with the Plan. The Exculpated
Persons shall have no liability to any Creditors or Interest holders for actions
taken or omissions made under the Plan, in connection therewith or with respect
thereto in good faith, including, without limitation, failure to obtain
Confirmation of the Plan or to satisfy any condition or conditions, or refusal
to waive any condition or conditions, precedent to Confirmation or to the
occurrence of the Effective Date. Further, the Exculpated Persons will not have
or incur any liability to any holder of a Claim, holder of an Interest, or
party-in-interest herein or any other Person for any act or omission in
connection with or arising out of their administration of the Plan or the
property to be distributed under the Plan, except for gross negligence or
willful misconduct as finally determined by the Bankruptcy Court, and in all
respects such Persons will be entitled to rely upon the advice of counsel with
respect to their duties and responsibilities under the Plan. Nothing contained

under the Acquisition Agreement or any contract, instrument, release or other
agreement or document created in connection with the Plan.

         14.2 ABSTENTION. If the Bankruptcy Court abstains from exercising
jurisdiction or is otherwise without jurisdiction over any matter arising out of
the Reorganization Case, including, without limitation, the matters set forth in
this Article, this Article shall have no effect upon and shall not control,
prohibit, or limit the exercise of jurisdiction by any other court having
competent jurisdiction with respect to such matter.


                                   ARTICLE XV

                            MISCELLANEOUS PROVISIONS

         15.1 FRACTIONAL DOLLARS. Any other provision of the Plan
notwithstanding, no payments of fractions of dollars will be made to any holder
of an Allowed Claim. Whenever any payment of a fraction of a dollar to any
holder of an Allowed Claim would otherwise be called for, the actual payment
made will reflect a rounding of such fraction to the nearest whole dollar (up or
down).

         15.2 MODIFICATION OF PLAN. The Debtors reserve the right, in accordance
with the Bankruptcy Code and the Acquisition Agreement, to amend or modify the
Plan prior to the entry of the Confirmation Order. After the entry of the
Confirmation Order, the Debtors or Reorganized Debtors, as the case may be, may,
upon order of the Bankruptcy Court, amend or modify the Plan in accordance with
section 1127(b) of the Bankruptcy Code, or remedy any defect or omission or
reconcile any inconsistency in the Plan in such manner as may be necessary to
carry out the purpose and intent of the Plan.

         15.3 WITHDRAWAL OF PLAN. The Debtors reserve the right, at any time
prior to entry of the Confirmation Order, to revoke or withdraw the Plan. If the
Debtors revoke or withdraw the Plan under this section 15.3 or if the Effective
Date does not occur, then the Plan shall be deemed null and void. In that event,
nothing contained in the Plan shall be deemed to constitute a waiver or release
of any Claims by or against the Debtors or any other person, or to prejudice in
any manner the rights of the Debtors or any other person in any further
proceedings involving the Debtors.

         15.4 GOVERNING LAW. Except to the extent the Bankruptcy Code, the
Bankruptcy Rules or the Delaware General Corporation Law are applicable, the
rights and obligations arising under the Plan shall be governed by, and
construed and enforced in accordance with the laws of the State of Texas,
without giving effect to the principles of conflicts of law thereof.

         15.5 TIME. In computing any period of time prescribed or allowed by
this Plan, the day of the act, event, or default from which the designated
period of time begins to run shall not be included. The last day of the period
so computed shall be included, unless it is not a Business Day or, when the act
to be done is the filing of a paper in court, a day on which weather or other
conditions have made the clerk's office

inaccessible, in which event the period runs until the end of the next day which
is not one of the aforementioned days. When the period of time prescribed or
allowed is less than eight days, intermediate days that are not Business Days
shall be excluded in the computation.

         15.6 PAYMENT DATES. Whenever any payment to be made under the Plan is
due on a day other than a Business Day, such payment will instead be made,
without interest, on the next Business Day.

         15.7 HEADINGS. The headings used in this Plan are inserted for
convenience only and neither constitute a portion of the Plan nor in any manner
affect the provisions of the Plan.

         15.8 SUCCESSORS AND ASSIGNS. The rights, benefits and obligations of
any entity named or referred to in the Plan shall be binding on, and shall inure
to the benefit of, any heir, executor, administrator, successor or assign of
such entity.

         15.9 SEVERABILITY OF PLAN PROVISIONS. If prior to Confirmation any term
or provision of the Plan, which does not govern the treatment of Claims or
Interests or the conditions of the Effective Date or which is not governed by
the terms of the Acquisition Agreement or documents related thereto, is held by
the Bankruptcy Court to be invalid, void, or unenforceable, the Bankruptcy Court
shall have the power to alter and interpret such term or provision to make it
valid or enforceable to the maximum extent practicable, consistent with the
original purpose of the term or provision held to be invalid, void, or
unenforceable, and such term or provision shall then be applicable as altered or
interpreted. Notwithstanding any such holding, alteration or interpretation, the
remainder of the terms and provisions of the Plan will remain in full force and
effect and will in no way be affected, impaired, or invalidated by such holding,
alteration, or interpretation. The Confirmation Order shall constitute a
judicial determination and shall provide that each term and provision of the
Plan, as it may have been altered or interpreted in accordance with the
foregoing, is valid and enforceable pursuant to its terms.

         15.10 NO ADMISSIONS. Notwithstanding anything herein to the contrary,
nothing contained in the Plan shall be deemed as an admission by the Debtors
with respect to any matter set forth herein, including, without limitation,
liability on any Claim or the propriety of any Claims classification.
