income tax return or a Joint Return has been filed, and (ii) the applicable
statute of limitations has not expired, UNOVA (or the appropriate member of the
UNOVA Group) shall file a refund claim pursuant to Code Section 6511 reflecting
such Tax Benefit (or a comparable provision of state law in the case of a Joint
Return). UNOVA shall, within 30 days after receipt, pay to Western Atlas any
refunds received by UNOVA resulting from the filing of a refund claim pursuant
to the preceding sentence, together with any interest refunded with respect
thereto. In the event that UNOVA would have received a refund with respect to
such claim had such refund not been offset by the United States Government (or
the relevant state government in the case of a Joint Return) against
deficiencies, interest or penalties assessed against UNOVA or any member of the
UNOVA Group, UNOVA shall pay to Western Atlas, within 30 days after receipt of
written notice of such offset, an amount equal to the amount of such offset,
together with interest at the overpayment rate established under Section 6621 of
the Code.

If, for any taxable year, UNOVA is required to and does make a repayment to the
IRS (or a state governmental authority in the case of a Joint Return) of any
portion of a refund described herein, then Western Atlas shall pay to UNOVA,
within 30 days following the date UNOVA notifies Western Atlas of such
repayment, the amount of such repayment, including related interest.

(e) In the event that UNOVA receives notice of a Reimbursable Adjustment that
generates a Tax Benefit for UNOVA or any member of the UNOVA Group for any
taxable period(s) with respect to which a federal income tax return or a Joint
Return has not been filed and UNOVA is unable to have such Tax Benefit flow
through to Western Atlas as described in Section 3.3(c), then UNOVA (or the
appropriate member of the UNOVA Group) shall file federal Form 1120(s) (or
corresponding form under relevant state law in the case of a Joint Return)
reflecting such Tax Benefit and shall pay to Western Atlas, no later than thirty
(30) days after the filing of such return(s), the amount by which such Tax
Benefit actually reduces the federal income taxes and/or Taxes with respect to a
Joint Return payable by UNOVA or such member of the UNOVA Group with respect to
such taxable period(s), using the appropriate statutory income tax rate
applicable to such period(s). If, pursuant to a Final Determination for any

<PAGE>

                                                                         Page 16

taxable year, UNOVA is required to and does make a payment to the IRS (or a
state governmental authority in the case of a Joint Return) representing any
portion of the amount paid to Western Atlas pursuant to the preceding sentence,
then Western Atlas shall pay to UNOVA, within 30 days following the date UNOVA
notifies Western Atlas of such payment to the IRS (or a state governmental
authority in the case of a Joint Return), the amount of such payment, including
related interest.

(f) Western Atlas may notify UNOVA of a Reimbursable Adjustment prior to the
Final Determination of such adjustment if Western Atlas, in its sole discretion,
determines that such Reimbursable Adjustment may, upon Final Determination,
generate a Tax Benefit for UNOVA with respect to which a refund claim may be
barred by the applicable statute of limitations. If Western Atlas so requests,
UNOVA shall file a refund claim for the appropriate taxable period(s) reflecting
such Tax Benefit, and shall pay to Western Atlas any Tax and interest refunded
with respect thereto under the terms and conditions set forth in subsection (c)
of this Section 3.3. All refund claims filed by UNOVA pursuant to this Section
3.3(e) shall be prepared in cooperation with Western Atlas, shall fully explain
the circumstances giving rise to the claim and shall be identified with the
notation "Protective Claim".

(g) If as a result of any audit, amendment or other change in a federal income
Tax Return or a Joint Return filed by Western Atlas or UNOVA with respect to any
period beginning after the Distribution Date, the Final Determination of an
adjustment to any Tax Item generates a Tax Detriment to UNOVA or any UNOVA
Business and a corresponding Tax Benefit for Western Atlas or any Western Atlas
Business for any period, then the provisions of subsections (b), (c), (d), (e)
and (f) of this Section 3.3 shall be applied by substituting Western Atlas for
UNOVA and UNOVA for Western Atlas, as the context requires.

(h) Any payment not made on or before the last day on which such payment could
be timely made under this Section 3.3 shall thereafter bear interest at the rate
established for large corporate underpayments pursuant to Section 6621(c)(1) of
the Code.

(i) Notwithstanding any provision of this Agreement to the contrary, the total
amount payable by UNOVA to Western Atlas with respect to any Reimbursable
Adjustment pursuant to subsections (c), (d) and/or (e) of this Section 3.3 shall
not exceed the amount of the Taxes paid by Western Atlas with respect to such
adjustment.

Section 3.4. CHANGE IN OTHER PRE-DISTRIBUTION YEAR STATE, LOCAL OR OTHER RETURN.
(a) Except as otherwise provided in this Section 3.4, if as a result of any
audit, amendment or other change in a state or local tax return (other than a
Joint Return) or any Other Tax Return filed with respect to any period beginning
before the Distribution Date, there is an adjustment to any Tax Item, then
Western Atlas shall be responsible for and shall hold UNOVA harmless from any
such adjustment generated by or attributable to Western Atlas or any Western
Atlas

<PAGE>

                                                                         Page 17

Business (a "Western Atlas Issue"), and UNOVA shall be responsible for and shall
hold Western Atlas harmless from any such adjustment generated by or
attributable to UNOVA or any UNOVA Business (a "UNOVA Issue"). Upon request by
Western Atlas, UNOVA or any member of the UNOVA Group shall use its reasonable
best efforts to cooperate in any contest of such UNOVA Issue.

(b) Any payment required to be made under this Section 3.4 shall be inclusive of
interest and penalties and shall be made no later than 30 days after the party
required to make such payment receives written notice of a Final Determination
of the Western Atlas Issue or UNOVA Issue, as the case may be, giving rise to
such payment; provided, however, that no payment shall be due under this Section
3.4 unless the total amount payable with respect to any individual state or
local return (other than a Joint Return) or Other Tax Return by Western Atlas or
by UNOVA, as the case may be, equals or exceeds $10,000 exclusive of interest
and penalties. Any payment not made within the 30-day period described in the
preceding sentence shall thereafter bear interest at the rate established for
large corporate underpayments pursuant to Section 6621(c)(1) of the Code.

Section 3.5. CHANGE IN PRE-DISTRIBUTION YEAR FOREIGN RETURN. Any legal entity
responsible for filing a foreign Tax Return with respect to any taxable period
beginning prior to the Distribution Date shall be responsible for the payment of
all Taxes, penalties and interest whenever assessed, due or payable in
connection therewith and shall be entitled to all refunds, whenever granted,
attributable thereto, regardless of whether such legal entity is a member of the
Western Atlas Group or the UNOVA Group before or after the Distribution Date.
Notwithstanding the foregoing, if a decrease in foreign Taxes results in a Tax
Detriment to Western Atlas and a corresponding Tax Benefit to UNOVA or any of
the UNOVA Businesses, UNOVA shall pay Western Atlas an amount equal to such Tax
Detriment. In the event that an increase in foreign Taxes results in a Tax
Benefit to Western Atlas and a corresponding Tax Detriment to UNOVA or any of
the UNOVA Businesses, Western Atlas shall pay UNOVA an amount equal to the
amount by which such Tax Benefit actually reduces the Taxes of Western Atlas.

Section 3.6. RESTRUCTURING TAXES. (a) Notwithstanding any other provision of
this Agreement to the contrary, and except as otherwise provided in this Section
3.6, Western Atlas shall pay fifty percent (50%) of all Restructuring Taxes and
UNOVA shall pay fifty percent (50%) of all Restructuring Taxes. UNOVA and each
member of the UNOVA Group will jointly and severally indemnify Western Atlas and
each member of the Western Atlas Group against and hold them harmless from any
payment of Restructuring Taxes in excess of fifty percent (50%) of such taxes,
and Western Atlas and each member of the Western Atlas Group will jointly and
severally indemnify UNOVA and each member of the UNOVA Group against and hold
them harmless from any payment of Restructuring Taxes in excess of fifty percent

(50%) of such taxes.

(b) In the event that any Restructuring Taxes are attributable to the
acquisition ("Acquisition") of fifty percent (50%) or more of the stock or
assets of Western Atlas or UNOVA by an Unrelated Person, then the party so
acquired, or the party whose assets were so acquired, as the case may be, shall
pay and shall indemnify and hold harmless the other party to this Agreement from
and against any and all Restructuring Taxes and from and against any costs
whatsoever connected with such Restructuring Taxes. For purposes of this Section
3.6(b), a Restructuring Tax is attributable to an Acquisition if the Acquisition
occurs prior to the assessment of such Restructuring Tax.

(c) Any payment required to be made pursuant to this Section 3.6 shall be made
no later than 30 days after the payor receives written notice of a Final
Determination of such Restructuring Taxes. Any payment not so made within 30
days shall thereafter bear interest at the rate established for large corporate
underpayments pursuant to Section 6621(c)(1) of the Code.

(d) Neither Western Atlas nor UNOVA shall engage in any acts, other than an
Acquisition, which would result in any Restructuring Taxes. In the event that
any Restructuring Taxes are attributable to such acts, the party so engaged
shall pay and shall indemnify and shall hold harmless the other party to this
Agreement from and against any such Restructuring Taxes.

incurs a net operating loss that may be carried back to a Pre-Distribution Year
in which such member was a member of the Western Atlas Consolidated Group, such
member shall make an election pursuant to Section 172(b)(3) of the Code, unless
Western Atlas, in its sole discretion, consents to treat such net operating loss
as a Carryback Item pursuant to paragraph (b) of this Section 3.9.

(b) If, for any taxable year beginning on or after the Distribution Date, a
member of the UNOVA Group (or a successor to such member) incurs a net capital

by the Western Atlas Consolidated Group, UNOVA (or such member of the UNOVA
Group) may file a refund claim pursuant to Code section 6411 reflecting such

<PAGE>

Carryback Item. In the event that UNOVA (or such member of the UNOVA Group)
shall not elect to file such a claim (or shall not be eligible to file such
claim under applicable law), Western Atlas shall, at the request and expense of
UNOVA, file amended returns or refund claims reflecting such Carryback Item.

interest or penalties attributable to (i) the operations of the UNOVA Group and
with respect to which the UNOVA Group would otherwise be responsible under the

to UNOVA, within 30 days after receipt of notice of such offset, an amount equal
to the amount of such offset, together with interest at the overpayment rate
established under Section 6621 of the Code. To the extent that a member of the

a result of this Section 3.9(b) and the operation of the Code, Western Atlas or
UNOVA, respectively, will compensate UNOVA or Western Atlas, respectively, for
the duplication of the benefit. If, for any taxable year, Western Atlas is
required to and does make a repayment to the IRS of any portion of a refund
described herein, then UNOVA shall pay to Western Atlas, within 30 days
following the date Western Atlas notifies UNOVA of such repayment, the amount of
such repayment, including interest.

Atlas of any inquiries by any taxing authority or any other administrative,

imposed on any member of the Western Atlas Group or any liability of any member
of the Western Atlas Group that might arise under this Agreement.

foreign tax receipts with respect to periods beginning before the Distribution

neither party or its employees shall make any voluntary disclosures to any

to retain all Tax Returns, related schedules and workpapers, and all material
records and other documents relating thereto existing on the date hereof or

be, fails to provide any information requested pursuant to Section 3.1(b)(1),
Section 3.2(a) or this Section 4.2 by (i) the date(s) specified in such Section
or (ii) if no date is specified, within a reasonable period, as determined in
good faith by the party requesting the information, then the requesting party
shall have the right to engage a public accountant of its choice to gather such
information. UNOVA and Western Atlas, as the case may be, agree upon 24 hours'
notice, in the case of a failure to provide information pursuant to Section
3.1(b)(1) or Section 3.2(a) of this Agreement, and otherwise upon 30 days'

other party requests that such documentation be retained, by written notice
describing in reasonable detail the documentation to be retained, and (ii) the

of such notice objects, then the party proposing the retention shall promptly
offer to take delivery of such materials from the objecting party at the expense

select a new arbitrator to fill the position. The arbitrator's fees and expenses
shall be borne equally by Western Atlas and UNOVA.

amount in dispute, which position shall be consistent with any notice provided
by such party pursuant to subsection (a) of this Section 5.15, together with a
copy of such notice.

(iii) The arbitrator shall base his decision on the following standards. In the
case of a factual dispute between the parties, the arbitrator shall make a

issue or a settlement amount, the arbitrator shall consider the strength of

raised by the taxing authority with whom the settlement was made in a

<PAGE>

                                                                         Page 28

to paragraph (ii) above proposed the amount closest to the aggregate of the
amounts so determined.

(iv) The arbitrator shall render a written decision stating only the amount of
such decision as soon as practicable. The arbitrator shall also orally explain
the bases of such decision to both parties as soon as practicable. If and only
if both parties request, the arbitrator shall state the bases of such decision
in writing. The arbitrator's decision shall be in an amount equal to one of the
total amounts asserted by one of the parties in the written statements submitted
pursuant to paragraph (ii) above. The arbitrator shall not, and is not
authorized to, render a decision in any other amount.

(v) The arbitrator's decision shall be final and binding on the parties.

counsel, by other requirements of law, all information (other than any such
information relating solely to the business or affairs of such party) concerning
the other parties hereto furnished it by such other party or its representatives

shown to have been (i) previously known by the party to which it was furnished,

lawfully acquired from other sources by the party to which it was furnished),
and each party shall not release or disclose such information to any other
person, except its auditors, attorneys, financial advisors, bankers and other
consultants and advisors who shall be advised of the provisions of this
Agreement. Each party shall be deemed to have satisfied its obligation to hold
confidential information concerning or supplied by the other party if it
exercises the same care as it takes to preserve confidentiality for its own
similar information.

Section 5.17. LIMITATION ON WAIVERS. The provisions of this Agreement may be
waived only if the waiver is in writing and signed by the party making the
waiver. No delay or omission in exercising any right under this Agreement will
operate as a waiver of the right on any further occasion. No waiver of any
particular provision of this Agreement will be treated as a waiver of any other
provision, and no waiver of any rights will be deemed a continuing waiver of the
same right with respect to subsequent occurrences that give rise to it. All
rights given by this Agreement are cumulative to other rights provided for in

                          ARBITRATION PROCEDURAL RULES

1. Administration and Conduct of Arbitration.

(a) At the discretion of the Arbitrator, an administrative conference with the
Arbitrator and the parties and/or their representatives will be scheduled in
appropriate cases to expedite the Arbitration proceedings.

(b) It is intended that the Arbitration be conducted in an expeditious manner
and without evidentiary hearing or oral presentation and argument, unless the
Arbitrator determines, at any time, that an evidentiary hearing, and/or oral
presentation or argument is desired by the Arbitrator for the rendition of an
award or a decision. However, the Arbitrator shall fix limits on the duration of
any such evidentiary hearing and/or oral presentation and argument, in advance,
with time equally divided between the parties.

(c) On such schedule as may be established by the Arbitrator, each of the
parties shall submit simultaneous briefs, including exhibits, to

<PAGE>

                                                                         Page 30

the Arbitrator supporting their respective positions. There shall be no limit to
the number of pages included in such briefs or to the number of exhibits. Each
party shall have a reasonable opportunity, as determined by the Arbitrator, to
reply to the brief of the other. The Arbitrator shall have the right to request
additional written statements of all or any of the parties; provided that each
party shall have the reasonable opportunity to reply to any such additional
statements submitted in response to the request of the Arbitrator.

2. Fixing of Locale.

The parties may mutually agree to the locale where the Arbitration is to be
held. If the parties cannot agree on the locale, the Arbitrator shall have the
power to determine the locale and its decision shall be final and binding.

3. Date, Time and Place of Hearing.

The Arbitrator shall set the date, time, and place for any hearing. The
Arbitrator shall mail to each party notice thereof at least ten days in advance,
unless the parties by mutual agreement waive such notice or modify the terms
thereof.

4. Postponements.

The Arbitrator for good cause show may postpone any hearing upon the request of
a party or upon the Arbitrator's own initiative, and shall also grant such
postponement when all of the parties agree thereto.

5. Oaths.

Before proceeding with the first hearing, the Arbitrator may take an oath of
office and, if required by law, shall do so. The Arbitrator may require
witnesses to testify under oath administered by any duly qualified person and,
if it is required by law, shall do so.

6. Order of Proceedings and Communication with Arbitrator.

(a) A hearing shall be opened by the filing of the oath of the Arbitrator, where
required, and by the recording of the date, time, and place of the hearing, and
the presence of the Arbitrator, the parties, and their representatives, if any.

(b) The Arbitrator may, at the beginning of the hearing, ask for statements
clarifying the issues involved.

(c) The complaining party shall then present evidence and/or argument, as
required by the Arbitrator, to support its claim. The defending

<PAGE>

                                                                         Page 31

party shall then present evidence and/or argument supporting its position and
responding to the position of the other. Witnesses, if any, for each party shall
submit to questions or other examination. The Arbitrator has the discretion to
vary this procedure but, within the time limits specified above, shall afford a
full and equal opportunity to all parties for the presentation of any material
and relevant evidence.

(d) Exhibits, when offered by either party, may be received in evidence by the
Arbitrator. The names and addresses of any witnesses and a description of the
exhibits in the order received shall be made a part of the record.

(e) There shall be no direct communication between the parties and the
Arbitrator other than at oral hearing, unless the parties and the Arbitrator
agree in writing.

7. Arbitration in the Absence of a Party or Representative.

Unless the law provides to the contrary, the Arbitration may proceed in the
absence of any party or representative who, after due notice, fails to be
present or fails to obtain a postponement ("absence in default"). An award shall
not be made solely on the default of a party. The Arbitrator shall require the
party who is present to submit such evidence as the Arbitrator may require for
the making of an award.

8. Evidence.

(a) The parties may offer such evidence as is relevant and material to the
dispute and shall produce such evidence as the Arbitrator may deem necessary to
an understanding and determination of the dispute.

(b) The Arbitrator shall be the judge of the relevance and materiality of the
evidence offered, and conformity to legal rules of evidence shall not be
necessary. All evidence shall be taken in the presence of the Arbitrator and all
of the parties, except where any of the parties is absent in default or has
waived the right to be present.

9. Evidence by Affidavit and Post-Hearing Filing of Documents or Other Evidence.

(a) The Arbitrator may receive and consider the evidence of witnesses by
affidavit, but shall give it only such weight as the Arbitrator deems it to be
entitled to after consideration of any objection made to its admission.

(b) If the parties agree or the Arbitrator directs that documents or other
evidence be submitted to the Arbitrator after the hearing, the documents or
other evidence shall be filed with the Arbitrator. All parties shall be afforded
an opportunity to examine such documents or other evidence.

<PAGE>

                                                                         Page 32

10. Closing of Hearing.

If satisfied that the record is complete, the Arbitrator shall declare the
hearing closed and a minute thereof shall be recorded. If briefs are to be
filed, the hearing shall be declared closed as of the final date set by the
Arbitrator for the receipt of briefs. If documents are to be filed as provided
in Section 9 and the date set for their receipt is later than that set for the
receipt of briefs, the later date shall be the date of closing of the hearing.

11. Reopening of Hearing.

The hearing may be reopened on the Arbitrator's initiative at any time before
the award is made. If reopening the hearing would prevent the making of the
award within the specified time limit, the matter may not be reopened unless the
parties agree on an extension of time.

12. Waiver of Oral Hearing.

The parties may provide, by written agreement, for the waiver of oral hearing in
any case.

13. Waiver of Rules.

Any party who proceeds with the Arbitration after knowledge that any provision
or requirement of these rules has not been complied with and who fails to state
an objection thereto in writing shall be deemed to have waived the right to
object.

14. Extensions of Time.

The parties may modify any period of time by mutual agreement. The Arbitrator
may for good cause extend any period of time established by these rules, except
the time for making the award. The Arbitrator shall notify the parties of any
extension.

15. Serving of Notice.

Each party shall be deemed to have consented that any papers, notices, or
process necessary or proper for the initiation or continuation of an Arbitration
under these rules, for any court action in connection therewith, or for the
entry of judgment on any award made under these rules may be served on a party
by mail addressed to the party or its representative at the last known address
or by personal service, in or outside the state where the Arbitration is to be
held, provided that reasonable opportunity to be heard with regard thereto has
been granted to the party.

16. Time of the Award.

The award shall be made promptly by the Arbitrator and, unless otherwise agreed
by the parties in writing or specified by law, no later than thirty days from
the date of closing the hearing, or, if oral hearings have not been held, from
the date of the transmittal of the final briefs, statements and proofs to the
Arbitrator.

17. Award upon Settlement.

If the parties settle their dispute during the course of the Arbitration, the
Arbitrator may set forth the terms of the agreed settlement in an award. Such an
award is referred to as a consent award.

18. Deliver of Award to Parties.

Parties shall accept as legal delivery of the award the placing of the award or
a true copy thereof in the mail addressed to a party or its representative at
the last known address, personal service of the award, or the filing of the
award in any other manner that is permitted by law.

19. Applications to Court and Exclusion of Liability.

(a) No judicial proceeding by a party relating to the subject matter of the
Arbitration shall be deemed a waiver of the party's right to arbitrate.

(b) Parties to these rules shall be deemed to have consented that judgment upon
the Arbitration award may be entered in any federal or state court having
jurisdiction thereof.

20. Interpretation and Application of Rules.

The Arbitrator shall interpret and apply these rules insofar as they relate to
the Arbitrator's powers and duties. If there is more than one Arbitrator and a
difference arises among them concerning the meaning or application of these
rules, it shall be decided by a majority vote.

21. Complex Procedures.

Notwithstanding the foregoing, if the parties mutually agree, any Arbitration to
be conducted between the parties may be concluded in the manner provided for in
the Supplementary Procedure for Large Complex Disputes of the American
Arbitration Association, with such modification as the parties may agree upon.

including all employees laid-off, disabled or on leave of absence, unless their
employment with the Western Atlas Group has been terminated. The UNOVA Group is
not obligated to employ any such employees of the Western Atlas Group who
decline employment with the UNOVA Group, and Western Atlas shall not be
obligated to continue the employment of such employees.

(b) Western Atlas and UNOVA agree that with respect to individuals who, in
connection with the Distribution, cease to be employees of the Western Atlas
Group and become employees of the UNOVA Group, such cessation shall not be
deemed a severance of employment from either Group for purposes of any Plan or
agreement that provides for the payment of severance, salary continuation or
similar benefits or stock repurchase rights and, in connection with the
Distribution, if and to the extent appropriate, Western Atlas and UNOVA shall
use their best efforts (without payment of monetary compensation) to obtain
waivers

from individuals against any such assertion.

(c) The UNOVA Group shall assume and be solely responsible for, and shall
indemnify the Western Atlas Group against, all liabilities and obligations
whatsoever in connection with claims made by or on behalf of UNOVA Employees or
UNOVA Former Employees in respect of severance pay, salary continuation and
similar obligations relating to the termination or alleged termination of any
such person's employment either before, on or after the Distribution Date.

Section 3. CASH BONUS PLANS.

(a) Western Atlas shall be responsible for the payment of all Liabilities for
benefits due and payable but unpaid as of and through the Distribution Date
under each Western Atlas Bonus Plan with respect to any Prior Plan Year (other
than the Current Plan Year), other than with respect to benefits due and payable
to UNOVA Participants or UNOVA Former Employees.

(b) Except as provided in paragraph (c) below, under each Western Atlas Bonus
Plan, the UNOVA Group shall be responsible for the payment of all Liabilities
for benefits to UNOVA Participants and UNOVA Former Employees due and payable
after the Distribution Date or due and payable but unpaid as of and through the
Distribution Date, including the portions of awards made prior to the
Distribution Date which are not payable prior to the Distribution Date.

(c) Prior to the Distribution Date, Western Atlas shall determine 1997 annual
bonus awards under the Western Atlas Bonus Plans for UNOVA Employees who are
Western Atlas corporate headquarters employees. Such awards shall be pro rated
based upon the portion of the 1997 bonus year which had expired as of the
Distribution Date. Western Atlas shall pay a portion of the cash bonus prior to
the Distribution Date (the bonus amount that is up to 50% of the employee's base
salary earned for 1997 prior to the Distribution Date), and UNOVA shall pay the
balance of the bonus following the Distribution Date in installments pursuant to
the terms of the Western Atlas Bonus Plans.

(d) Following the end of 1997, UNOVA shall determine 1997 annual bonus awards
for UNOVA Employees who were not Western Atlas corporate headquarters employees,
and shall make such payments to such UNOVA Employees.

(e) For purposes of the Western Atlas Bonus Plans, individuals who, in

<PAGE>

                                                                          Page 7

connection with the Distribution, cease to be employees of Western Atlas and
become UNOVA Employees shall not be deemed to have terminated employment under
such Plans as a result of becoming UNOVA Employees for purposes of receiving
installments of prior year "Final Awards" under the Western Atlas Bonus Plans.
To the extent applicable, for purposes of receiving payments of installments of
prior year "Final Awards" under the Western Atlas Bonus Plans, UNOVA Employees
must at the time such payment is due (i) be in the active employ of UNOVA or a
Subsidiary or Affiliate of UNOVA, (ii) have terminated employment with UNOVA by
reason of death, or "Disability" or "Retirement" (as defined in the UNOVA Option
Plan) or (iii) be on an "Approved Leave of Absence" (as determined by the UNOVA
Compensation Committee or, prior to the Distribution, by the Western Atlas
Compensation Committee but including, without limitation, a leave of absence for
purposes of service in the Armed Services of the United States).

Section 4. STOCK OPTIONS.

Western Atlas shall take all action necessary to amend (if necessary), or
otherwise provide for adjustments of outstanding awards under, the Western Atlas
Stock Option Plan, so that each outstanding Western Atlas Option will be
adjusted by (i) multiplying the number of shares of Western Atlas Common Stock
subject to the option by the Adjustment Factor and (ii) dividing the exercise
price per share of the option by the Adjustment Factor. For these purposes, the
"Adjustment Factor" is defined as the quotient obtained by dividing (x) the
Average Market Price of the Western Atlas Common Stock plus the Average Market
Price of the UNOVA Common Stock by (y) the Average Market Price of the Western
Atlas Common Stock. The "Average Market Price" of Western Atlas Common Stock or
UNOVA Common Stock, as the case may be, is defined to be the average of the high
and low daily prices of such security as reported on the NYSE Composite Tape
(or, if not listed on such exchange, on any other national securities exchange
on which the Western Atlas Common Stock or the UNOVA Common Stock is listed or
on NASDAQ) on the sixth through tenth trading days, inclusive, following the
Distribution Date. Each Western Atlas Option held by a UNOVA Employee who, in
(a) connection with the Distribution, ceases to be a Western Atlas Employee and
becomes a UNOVA Employee, shall be amended to provide that (i) service with
UNOVA shall be deemed continuous service with Western Atlas for purposes of
vesting, exercisability and the duration of such Western Atlas Option and (ii)
to avoid the potential loss of the opportunity to exercise such Western Atlas
Option following a "Change in Control" of UNOVA (as defined in the UNOVA Option
Plan), such Western Atlas Option

<PAGE>

                                                                          Page 8

held by UNOVA Employees shall immediately vest and become exercisable upon a
Change in Control of UNOVA. Each Western Atlas Option held by a UNOVA-only
Director shall be vested and exercisable in full on the Distribution Date, and
each such Western Atlas Option shall remain exercisable until the later of (A)
ten years following the date of grant of such option by Western Atlas and (B)
three years following the first to occur of the date of retirement or
resignation of the UNOVA-only Director as a director of UNOVA (or the failure of
such UNOVA-only Director to be re-elected as a director of UNOVA), the
UNOVA-only Director's total or permanent disability or his death.

Section 5. QUALIFIED PLANS.

(a) Effective on or prior to the Distribution Date, UNOVA shall assume
sponsorship of the Existing Retirement Plans. The Western Atlas Inc. Retirement
Plan shall be renamed the UNOVA, Inc. Pension Plan. The other two Existing
Retirement Plans will remain as frozen plans with no further benefit accruals
thereunder. The UNOVA, Inc. Pension Plan shall continue to provide benefits for
all individuals who, immediately prior to the Distribution Date, were
participants in the Western Atlas Inc. Retirement Plan. UNOVA agrees that each
such participant shall be, to the extent applicable, entitled, for all purposes
under the UNOVA, Inc. Pension Plan (including, without limitation, eligibility,
vesting and benefit accrual), to be credited with the term of service credited
to such participant as of the Distribution Date under the terms of the Western
Atlas Inc. Retirement Plan as if such service had been rendered to UNOVA and had
originally been credited to such participant under the UNOVA, Inc. Pension Plan
and shall have the same accrued benefit under the UNOVA, Inc. Pension Plan
immediately following the Distribution Date as was accrued under the Western
Atlas Inc. Retirement Plan as of the Distribution Date. Western Atlas shall, as
soon as practicable after the Distribution Date, provide UNOVA with such
additional information (in the possession of the Western Atlas Group and not
already in the possession of the UNOVA Group) as may be reasonably requested by
UNOVA and necessary in order for the UNOVA Group to establish and administer
effectively the Existing Retirement Plans assumed by UNOVA.

(b) Effective on or prior to the Distribution Date, UNOVA shall assume
sponsorship of the Western Atlas FSSP and the Western Atlas FSSP shall be
renamed the UNOVA, Inc. Financial Security and Savings Program (the "UNOVA
FSSP"). UNOVA agrees that all service credited under the Western Atlas FSSP as
of the Distribution Date with respect to Western Atlas FSSP participants shall
be credited under the UNOVA FSSP for all

<PAGE>

                                                                          Page 9

Plan purposes, including eligibility and vesting.

(c) From and after the Distribution Date, the Western Atlas Group shall cease to
have any Liability whatsoever with respect to participants under the Western
Atlas Inc. Retirement Plan or the Western Atlas FSSP, and UNOVA and the UNOVA,
Inc. Pension Plan and the UNOVA FSSP, as the case may be, shall assume or retain
sole responsibility for, and shall indemnify the Western Atlas Indemnitees with
respect to, all Liabilities of either Group with respect to participants under
the UNOVA, Inc. Pension Plan and the UNOVA FSSP.

Section 6. NONQUALIFIED RETIREMENT PLANS.

Effective as of the Distribution Date, UNOVA shall assume, and shall indemnify
the Western Atlas Indemnitees from and against, all Liabilities with respect to
(i) the Supplemental Retirement Agreement between Western Atlas Inc. and Alton
J. Brann (dated March 17, 1994) and all participants under the Western Atlas
Inc. Restoration Plan, (ii) UNOVA Participants and UNOVA Former Employees under
the Western Atlas Inc. Supplemental Executive Retirement Plan and (iii)
UNOVA-only Directors under the Western Atlas Inc. Deferred Compensation Plan for
Directors.

UNOVA represents that it has established plans on substantially the same terms
as the Western Atlas Nonqualified Plans pursuant to which each participant for
whom UNOVA has assumed Liabilities will be credited with the term of service
credited to such participant as of the Distribution Date under the Western Atlas
Nonqualified Plans, as if such service had been rendered to UNOVA.

Section 7. DEFERRED COMPENSATION.

Effective as of the Distribution Date, UNOVA shall assume and indemnify the
Western Atlas Indemnitees from and against all Liabilities with respect to UNOVA
Participants and UNOVA Former Employees in connection with any deferred
compensation plans.

Section 8. WELFARE PLANS.

(a) Effective on or prior to the Distribution Date, UNOVA shall assume the
Western Atlas Inc. Employees Welfare Benefit Trust, and such trust shall be
renamed the UNOVA, Inc. Employees Welfare Benefit Trust (the "UNOVA Trust").
Effective as of the Distribution Date, UNOVA shall be responsible for and shall
indemnify the Western Atlas Indemnitees from and against all Liabilities arising
under any Welfare Plan with respect

<PAGE>

                                                                         Page 10

to claims by UNOVA Participants or UNOVA Former Employees for benefits incurred
prior to or after the Distribution Date pursuant to the terms of the applicable
Plan.

(b) Effective on or prior to the Distribution Date, UNOVA shall assume
sponsorship of the Welfare Plans maintained by Western Atlas in which UNOVA
Employees participate. In connection with the foregoing, Western Atlas agrees to
provide UNOVA or its designated insurance representative with such information
(in the possession of the Western Atlas Group and not already in the possession
of the UNOVA Group) as may be reasonably requested by UNOVA and necessary for
the UNOVA Group to assume or establish any such Welfare Plan, and UNOVA agrees
to provide Western Atlas or its designated insurance representative with similar
information. Split-dollar insurance policies noted on Exhibit A as UNOVA
policies shall be assumed by UNOVA, and split-dollar insurance policies noted on
Exhibit A as Western Atlas policies shall remain with Western Atlas.

Section 9. WESTERN ATLAS MISCELLANEOUS PLANS; POST-DISTRIBUTION LIABILITIES.

(a) The Western Atlas Group shall be solely responsible for the payment of all
Liabilities whatsoever with respect to any Western Atlas Participant or Western
Atlas Former Employee unpaid as of and through the Distribution Date under any
Western Atlas Miscellaneous Plan and the UNOVA Group shall assume and be solely
responsible for the payment of all Liabilities with respect to any UNOVA
Participant or UNOVA Former Employee unpaid as of and through the Distribution
Date under any Western Atlas Miscellaneous Plan.

(b) Except as otherwise expressly provided herein, the Western Atlas Group shall
be solely responsible for the payment of all Liabilities whatsoever arising with
respect to any Western Atlas Employee or Western Atlas Former Employee and
attributable to any period subsequent to the Distribution Date and the UNOVA
Group shall be solely responsible for the payment of all Liabilities whatsoever
arising with respect to any UNOVA Employee or UNOVA Former Employee and
attributable to any period subsequent to the Distribution Date.

Section 10. PRESERVATION OF RIGHTS TO AMEND OR TERMINATE PLANS.

Western Atlas or UNOVA that it, or any member of the Western Atlas Group or the
UNOVA Group, will make or has made a contribution or payment to or under any
Plan herein referred to for any

<PAGE>

                                                                         Page 11

period, shall be construed as a limitation on the right of Western Atlas or
UNOVA or any member of the Western Atlas Group or the UNOVA Group to amend such
Plan or terminate its participation therein which Western Atlas or UNOVA or any
member of the Western Atlas Group or the UNOVA Group would otherwise have under
the terms of such Plan or otherwise, and no provision of this Agreement shall be
construed to create a right in any employee or former employee or beneficiary of
such employee or former employee under a Plan which such employee or former
employee or beneficiary would not otherwise have under the terms of the Plan
itself.

Section 11. REIMBURSEMENT; INDEMNIFICATION.

Each of the parties hereto acknowledges that the Western Atlas Group, on the one
hand, and the UNOVA Group, on the other hand, may incur costs and expenses
(including contributions to Plans and the payment of insurance premiums) arising
from or related to any of the Plans which are, as set forth in this Agreement,
the responsibility of the other party hereto. Accordingly, Western Atlas and
UNOVA agree to reimburse each other, as soon as practicable but in any event
within 30 days of receipt from the other party of appropriate verification, for
all such costs and expenses.

Section 12. TRANSFER OF RESERVES.

To the extent that any Liability assumed by any member of the UNOVA Group
hereunder is secured by a reserve on the books of Western Atlas, such reserve
shall be transferred from Western Atlas to the books of UNOVA as soon as
practicable on or following the Distribution Date.

Section 13. FURTHER TRANSFERS.

Western Atlas and UNOVA recognize that there may be UNOVA Employees who will,
after the Distribution Date, become employed by Western Atlas and there may be
Western Atlas Employees who become employed, after the Distribution Date, by
UNOVA and there may be UNOVA Former Employees or Western Atlas Former Employees
who are hired by Western Atlas or UNOVA, respectively. If Western Atlas and
UNOVA so agree with respect to any such individuals, the assets and liabilities
with respect to such employees which are associated with the plans and programs
described in this Agreement may be transferred and assumed in a manner
consistent with this Agreement and such employees will be treated as Western
Atlas Employees or UNOVA Employees, as the case may be. Any such transfers

<PAGE>

                                                                         Page 12
