          9.3.4 STAFF SERVICES. Except as otherwise provided in any of the
Related Agreements, in the event that any party to this Agreement desires that
any other party hereto provide any staff or other similar services to the party
requesting the services at any time following the Closing and the party to
provide the services determines that such requested services may be provided by
its existing staff departments or employees and that it has personnel available
for such purposes, such services will be provided to the requesting party on
terms to be mutually agreed upon by such parties.

                                       36


          9.3.5 ACTIONS TO ELIMINATE OBLIGATIONS. If requested by Eaton at any
time and from time to time after Closing, ESEI shall (in addition to any more
specific undertakings provided herein), promptly use its reasonable best
efforts to obtain Eaton's immediate and complete release from any continuing
obligations under any contract, lease or agreement of any sort which has been
assigned and transferred to ESEI under this Agreement or any Related Agreement.

          9.3.6 SHORT-TERM WORKING CAPITAL LOANS. In the event that ESEI does
not have working capital loan arrangements in place with banking institutions at
any time, Eaton may consider extending short-term working capital loans to ESEI
("Short-Term Loans") in such amounts, if any, as Eaton deems appropriate. The
Short-Term Loans would be on an unsecured basis, bearing interest at a rate
agreed upon by both parties.

          9.3.7 CONFIDENTIALITY. All of the non-public information related to
the transactions which are the subject of this Agreement which Eaton or any of
its subsidiaries has provided ESEI is confidential, as are this Agreement, the
Related Agreements, the closing documents and all matters related to the
transactions. ESEI shall limit the distribution and use of all non-public
information to the carrying out of the transactions, and will not disclose the
contents of this

                                       37

the prior consent of Eaton, except as required by applicable regulations and
rulings of any government or any taxing authority, any governmental agency
regulating the issuance or sale of securities or any court.

          9.3.8 PERSONAL PROPERTY TAXES. Ad valorem taxes imposed upon consigned
Inventories shall be remitted and borne in their entirety by ESEI and ad valorem
taxes upon Acquired Assets other than the Leaseholds (the "Personal Property
Taxes") shall be remitted and borne in their entirety by the party which has the
obligation under the applicable government law to return and pay such Personal
Property Taxes, and no prorations, apportionments or reimbursements of Personal
Property Taxes shall be made between the parties. The parties shall fully
cooperate to avoid, to the extent legally possible, the payment of duplicate
Personal Property Taxes, and each party shall furnish, at the request of the
other, proof of payment of any Personal Property Taxes or other documentation
which is a prerequisite to avoiding payment of a duplicate tax.

          9.3.9 PAYROLLS, OTHER TAXES AND EXPENSES.

               (i) Payrolls of Eaton Employees owed by Eaton for employment in
          the Business prior to the Closing Date shall be paid by Eaton or
          accrued on the Closing Date Balance

   39
                                       38

thereof prior to the Closing Date shall be borne and paid by Eaton, and all such

including recording fees, sales, use, transfer and license taxes and other
incidental costs applicable to the transaction. With respect to those items
which are exempt from sales or use tax on any basis, ESEI shall deliver to Eaton
appropriate certificates establishing the basis for the exemption. Each party
will cooperate to the extent practicable in minimizing all taxes, fees and costs
levied by reason of the sale and conveyance of the Acquired Assets.

                   ARTICLE 10. EMPLOYEES AND EMPLOYEE MATTERS
                   ------------------------------------------

     10.1 EMPLOYMENT. As of the Closing Date, ESEI shall offer immediate
employment (so that no period of unemployment shall

   40
                                       39


occur between employment with Eaton prior to the Closing Date and employment
with ESEI on and after the Closing Date) to all of the employees of Eaton who
are employed in the Business immediately prior to the Closing Date (the "Eaton
Employees"), including without limitation the Eaton Employees who then are on
layoff and subject to recall, or on disability leave of absence or any other
leave of absence. Such employment shall be offered on terms and conditions as to
salary and remuneration, including incentive compensation, and as to employee
fringe benefits, which are at least equal to such terms and conditions provided
for and on behalf of such Eaton Employees immediately prior to the Closing Date
by Eaton in accordance with Eaton's then established plans, programs, practices,
and arrangements, including without limitation the Eaton fringe benefit plans,
programs, practices, and arrangements listed on Schedule 10.1 (the "Eaton
Welfare Plans"). Effective as of the Closing Date, Eaton hereby assigns to ESEI,
and ESEI hereby assumes, any and all liabilities, responsibilities, and
obligations of Eaton to and on behalf of the Employees for the provision of such
salary, remuneration, and fringe benefits, and ESEI shall recognize any and all
periods of employment of each Employee prior to the Closing Date with Eaton
and/or any predecessor employer thereof for all purposes, including without
limitation for the purposes

   41
                                       40


of determining such Employee's eligibility for and amount of benefits, under
ESEI's compensation and/or fringe benefit plans, programs, practices, and/or
arrangements as if such Employee had been so employed by ESEI. However, the
assumption herein by ESEI of the foregoing liabilities, responsibilities, and
obligations shall not in any way or at any time create any third party
beneficiary rights for or on behalf of any person or persons other than the
parties to this Agreement. During the period of thirty-six (36) consecutive
months beginning on the Closing Date, ESEI shall neither employ nor offer
employment, without the prior written consent of Eaton, to any Eaton Employee
who does not become an Employee, or to any Retired Employee.

     10.2 SEVERANCE PAYMENT RESPONSIBILITIES. As of and after the Closing Date,
ESEI shall assume all liabilities, responsibilities, and obligations for
severance payments or other separation benefits to which any Eaton Employee may
be or become entitled or claim to be entitled as a result of ESEI's acquisition
of the Business, including without limitation any such claim which might be made
against either Eaton or ESEI at any time

          (a) by any Employee because of the transfer of his employment from
Eaton to ESEI; or

   42
                                       41


          (b) by any Employee because of termination of his employment by ESEI,
or because of any change of his compensation or fringe benefits or employment
position by ESEI, on or after the Closing Date; or

          (c) by any Eaton Employee because his employment with Eaton ceases as
a result of ESEI's acquisition of the Business. ESEI agrees to, and shall,
indemnify and hold harmless Eaton against and from any and all such claims and
any and all expenses, liabilities, obligations, and costs of any sort
associated therewith.

     10.3 WELFARE BENEFIT RESPONSIBILITIES.

          (a) As of and after the Closing Date, Eaton hereby assigns to ESEI,
and ESEI hereby assumes from Eaton, all liabilities, responsibilities, and
obligations for providing to all Eligible Individuals (as hereinafter defined)
life insurance, accidental death and dismemberment insurance, business travel
accident insurance, disability salary continuation, short term disability,
long-term disability, comprehensive health, dental, mail order drug, and patient
services benefits which are at least equal to such benefits as provided for such
Eligible Individuals by Eaton immediately prior to the Closing Date pursuant to
the applicable Eaton Welfare Plans. Such assignment of liabilities,

   43
                                       42


responsibilities, and obligations to, and assumption by, ESEI shall be
applicable to any and all claims for any such benefits which are or have been
filed on, prior or subsequent to the Closing Date by or on behalf of any
Eligible Individual with either Eaton or ESEI, or with any authorized
representative of either, and which claims have not been paid or otherwise fully
settled under the applicable Eaton Welfare Plan prior to the Closing Date,
notwithstanding (1) the date on which any such Eligible Individual's disability
or medical need commenced, or (2) the date on which any covered health, dental,
drug, and/or other services and/or materials and/or supplies were provided, or
(3) the date on which any covered expenses were incurred, or (4) the period
during which such Eligible Individual is eligible for benefit payments of any
kind, except as otherwise provided in Section 10.3(b). Welfare benefit coverage
hereby assumed by ESEI for the Eligible Individuals nevertheless shall be
provided under Eaton's applicable welfare benefit plans, programs, practices,
and/or arrangements until such time as ESEI establishes its own welfare benefit
plan, programs or arrangements (the "ESEI Welfare Plans"). Any Eligible
Individual's periods of employment with Eaton and/or any predecessor employer
thereof, and any and all periods of an Eligible Individual's coverage and/or
participation in any Eaton
   44
                                       43


Welfare Plan, shall be deemed to be employment with ESEI and coverage and/or
participation in the ESEI Welfare Plans respectively for all purposes of
establishing such Eligible Individual's eligibility for participation and
benefit entitlement under the ESEI Welfare Plans. The extent to which any
Eligible Individual (either as an individual or a family member) has satisfied
in whole or in part any Eaton Welfare Plan annual deductible, or has paid any
out-of-pocket expense pursuant to any Eaton Welfare Plan co-insurance provision,
shall be counted toward the satisfaction of any similar applicable deductible or
out-of-pocket expense maximum respectively under any applicable ESEI Welfare
Plan. For the purposes of this Article 10, "Eligible Individuals" shall mean

               (i) the Employees; and

               (ii) the eligible dependents and/or other eligible beneficiaries
          of the Employees;

who were eligible, or who would have become eligible, for any such welfare
benefits under any applicable Eaton Welfare Plan as of or after the Closing
Date.

          (b) Notwithstanding any other provisions of this Agreement to the
contrary, Eaton shall retain all liabilities, responsibilities, and obligations
under the applicable Eaton Welfare Plans with respect to any Eligible Individual
for the


   45
                                       44


provision of any life, accidental death and dismemberment, and/or business
travel accident insurance benefits payable with respect to any qualified death
or accident which occurs prior to the Closing Date.

          (c) In conjunction with the assignment to, and assumption by, ESEI of
liabilities, responsibilities, and obligations for the provision of welfare
benefits pursuant to Section 10.3(a), Eaton and ESEI agree that Eaton shall
arrange for the provision of life insurance, accidental death and dismemberment
insurance, business travel accident insurance, long term disability,
comprehensive health, dental, mail order drug, and patient services benefit
coverage on ESEI's behalf through the administrative services of the Eaton
Welfare Plans commencing on the Closing Date and continuing until such time as
Eaton and ESEI shall agree otherwise. ESEI agrees to pay to Eaton or, if so
determined by Eaton, to any administrative representative of Eaton, the premium
rates and/or direct costs of such benefits as provided through the Eaton Welfare
Plan administration, plus any third party administrative service fees related to
the provision of such benefits and any other reasonable related expenses
incurred by Eaton, or by any administrative representative of Eaton, for any
such continuing coverage or the financing thereof through Eaton Welfare Plan
   46
                                       45


administration. ESEI acknowledges that Eaton has agreed to the provisions of
this Section 10.3(c) as an accommodation to ESEI for the purposes of
facilitating the sale of the Business as contemplated by this Agreement, and
that this Section 10.3(c) shall in no way be construed to impose upon Eaton any
liability, responsibility, or obligation whatever for the provision of any
benefits for or on behalf of any Eligible Individual except as expressly set
forth in this Section 10.3.

          10.4 INVESTMENT PLAN RESPONSIBILITIES. As of the Closing Date and
thereafter until such time as Eaton may determine otherwise, Eaton shall extend
coverage under the Eaton Corporation Share Purchase And Investment Plan (the
"Eaton Investment Plan") to ESEI as the "Company" pursuant to the definition
thereof as set forth in Section 2.1(viii) of such Plan, and eligibility for
membership in the Eaton Investment Plan shall be extended to all Employees, and
to all new employees of ESEI hired on or after the Closing Date, pursuant to the
definition of "Employee" as set forth in Section 2.1(xix) of the Eaton
Investment Plan. Each Employee's employment with ESEI from and after the Closing
Date shall continue to be considered as employment with the "Company" for all
purposes under the Eaton Investment Plan so long as ESEI continues to be so
designated as the "Company", and the transfer of an

   47
                                       46


Employee's employment as of the Closing Date from Eaton to ESEI shall not be
deemed to be a break in his employment with the "Company" for purposes of his
membership, and eligibility for membership, in the Eaton Investment Plan. ESEI
shall have all liability, responsibility, and obligation for any and all
expenses relating to the operation of the Eaton Investment Plan with respect to
membership therein by Employees and new Employees of ESEI and shall reimburse
Eaton promptly for such expenses upon Eaton's presentation of an invoice
therefor to ESEI. Eaton shall amend the Eaton Investment Plan, if and to the
extent that it is considered necessary by Eaton, and shall take whatever other
actions that Eaton may deem necessary, to implement the provisions of this
Section 10.4.

          10.5 VACATION RESPONSIBILITIES. ESEI shall be liable, responsible, and
obligated for the payment of all vacation benefits on behalf of any and all
Employees, and which have not been paid by Eaton prior to the Closing Date.

          10.6 WORKERS' COMPENSATION RESPONSIBILITIES. As of the Closing Date,
ESEI shall assume, and shall pay or discharge as they come due, all liabilities,
responsibilities, and obligations for any loss, claim, or damage, including
without limitation any interest charges, and/or retroactive premiums for
workers' compensation insurance and/or penalties and/or

   48
                                       47


attorney's fees or disbursements, which is or has been incurred or suffered by
any Employee and which loss, claim, or damage is based upon any claim or demand
made by or on behalf of such Employee pursuant to any governmental workers'
compensation, occupational disease or injury, or substantially similar law,
regardless of whether such claim or demand is or was first presented, filed, or
actually made prior to, or on or after, the Closing Date and regardless of the
date of occurrence of any bodily injury, disease, or other physical or mental
condition upon which such claim or demand is or was based.

          10.7 REIMBURSEMENT FOR ESEI LIABILITIES. Notwithstanding any other
provisions of this Agreement to the contrary, in the event that Eaton shall be
required, by operation of law or regulation or by judicial or quasi-judicial
determination or by operation of any contract or other agreement of any kind
with any insurance company or other entity, to pay or discharge directly, or
indirectly through any representative or any benefit trust or other fund or
otherwise, any liability, responsibility, or obligation for the provision of any
benefit or other payment which is the liability, responsibility, and/or
obligation of ESEI either directly or indirectly pursuant to this Article 10,
ESEI shall promptly reimburse Eaton, or any appropriate representative or
benefit trust or other fund of

   49
                                       48


Eaton as may be determined by Eaton, in full for any and all such payments
and/or discharges upon the presentation of written evidence thereof by Eaton to
ESEI. ESEI also shall promptly reimburse Eaton for the full amount of any
benefit premium payment or other direct cost of benefit coverage which is
incurred by Eaton on ESEI's behalf with respect to any period of benefit
coverage occurring on or after the Closing Date.

     10.8 PROFIT SHARING PLAN. After the Closing, the Employees shall continue
to participate under the Semiconductor Equipment Operations Profit Sharing Plan
(the "SEO Plan") on the same terms and conditions as existed immediately prior
to the Closing, subject to any discontinuance, termination or amendment of the
SEO Plan adopted after the Closing.
