                                  Amtech Corporation

     The information previously reported in UNOVA's Schedule 13D, dated 
November 3, 1997, as amended and supplemented by Amendment No. 1 thereto 
dated April 17, 1998 (as so amended and supplemented, such filing is 
hereinafter referred to as the "UNOVA 13D") is hereby further amended and 
supplemented with the following information.  Terms used herein and not 
otherwise defined have the meanings given to such terms in the UNOVA 13D.



Item 4.   PURPOSE OF TRANSACTION

     As previously reported in the UNOVA 13D, UNOVA purchased the Shares to 
induce the Company to negotiate a research and development alliance with 
UNOVA for the purpose of developing and marketing radio frequency 
identification ("RFID") technology.  In March 1998, UNOVA disclosed that it 
and the Company had been unable to agree on the structure of a proposed 
product development alliance and were exploring other mutually agreeable 
means to complete the RFID development.

                                                               ---    --- 

     On April 9, 1998, UNOVA and the Company announced they had signed a 
letter of intent  with respect to the proposed purchase by UNOVA or one of 
its subsidiaries of the Company's RFID business unit known as the 
Transportation Systems Group.  On June 11, 1998, UNOVA and two of its 
subsidiaries, on the one hand, and Amtech and one of its subsidiaries on the 
other hand, entered into a definitive Purchase and Sale Agreement ("the 
"Purchase and Sale Agreement"), pursuant to which certain subsidiaries of 
UNOVA agreed to purchase the assets or stock of certain subsidiaries of the 
Company constituting the Transportation Systems Group.  The transaction was 
consummated on June 11, 1998.

     As the estimated purchase price for the Transportation Systems Group, 
which is subject to adjustment, UNOVA paid, or caused to be paid, to the 
Company or a subsidiary of the Company cash in the amount of $20,100,000, and 
UNOVA transferred and assigned to the Company the 2,211,900 shares of the 
Common Stock of the Company then owned by UNOVA. As a result of this 
transaction, UNOVA presently owns no Shares and has no right to acquire 
Shares.

     Upon transfer of the Shares, UNOVA ceased to have the rights granted 
under the Agreement, including the right to designate a nominee for election 
to the Company's Board of Directors.  However the Company's designee then 
serving on the Company's Board, Michael E. Keane, agreed to continue as a 
director of the Company but not as a designee of UNOVA.

     The Company has agreed, within ten business days following the purchase 
and sale of the Transportation Systems Group, to adopt a fictitious name that 
does not include "Amtech" or any derivative thereof.



Item 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
          TO SECURITIES OF THE ISSUER

     Item 6 of the UNOVA 13D is hereby amended and supplemented to reflect 
the information set forth above with respect to the transactions provided for 
in the Purchase and Sale Agreement.


Item 7.   MATERIAL TO BE FILED AS EXHIBITS

Technologies Corporation and Intermec Technologies S.A. on the one part and 
Amtech Corporation and Amtech International S.A. on the other part dated June

     1.6    CONSIDERATION.  For and in consideration of the transfer to 
Intermec of the Shares and the transfer to French Subsidiary of the Purchased 
Assets, (i) UNOVA (as agent for Intermec) shall, on and as of the dates 
indicated in Section 1.7, pay and remit to Amtech the "Non-French Purchase 
Price" (as defined in Section 1.7(a)(i) below), in accordance with and to the 
extent provided in Section 1.7, and (ii) French Subsidiary shall (a) on and 
as of the dates indicated in Section 1.7, pay and remit to AI the "French 
Purchase Price" (as defined in Section 1.7(a)(i) below), and (b) on the 
Closing Date but effective as of the Transfer Date, assume the "Assumed 
Liabilities" (as defined in Section 1.8), in accordance with and to the 
extent provided in Section 1.8 (as limited by Section 1.9).

     1.7    PURCHASE PRICE AND PAYMENT.

            (a)     DETERMINATION OF PURCHASE PRICE.

                    (i)    The purchase price (the "Purchase Price") for the 
Shares and the Purchased Assets is the amount equal to the "Closing Net Book 
Value" (as defined below) PLUS $1,650,000 (the "Premium"); PROVIDED, HOWEVER, 
that if the value of the 2,211,900 shares of common stock of Amtech held by 
UNOVA (the "UNOVA Shares") (based on the closing market price on NASDAQ on 
the Closing Date) (the "UNOVA Shares Value") is greater or less than 
$10,000,000 (which is the amount paid by UNOVA for the UNOVA Shares on 
November 3, 1997), the Purchase Price shall be increased or decreased by the 
amount of such difference.  The "Closing Net Book Value" shall mean the net 
book value of the net assets of Adjusted TSG as of the Transfer Date, as 
reflected on a balance sheet of Adjusted TSG as of the Transfer Date (the 
"Final Closing Balance Sheet"), prepared in accordance with subparagraph (ii) 
below.  The "French Purchase Price" shall mean that portion of the Closing 
Net Book Value representing the Purchased Assets and Assumed Liabilities of 
AI; and the "Non-French Purchase Price" shall mean the Purchase Price less 
the French Purchase Price.

                    (ii)   The Final Closing Balance Sheet shall be prepared 
in accordance with generally accepted accounting principles ("GAAP") applied 
on a basis consistent with that used in the preparation of the "December 
Balance Sheet" (as defined in Section 3.2(a)); PROVIDED, HOWEVER that (1) the 
Final Closing Balance Sheet shall not include (A) those portions of Amtech 
and its consolidated subsidiaries that are not part of Adjusted TSG, (B) any 
of the Excluded Assets or Unassumed Liabilities of AI, (C) any assets or 
liabilities related to any federal income Taxes, and (D) the Brazilian Notes, 
(2) any amount that will become payable by any member of TSG to any 
"Employee" (as defined in Section 3.15(a) or any third party) as a 
consequence of the Closing ("Change 


                                       5


<PAGE>

of Control Payments") shall be reflected as a liability on the Final Closing 
Balance Sheet, (3) the Final Closing Balance Sheet shall include such other 
adjustments as are described on Exhibit A-2, and (4) all account balances 
denominated in foreign currencies shall be translated into United States 
Dollars using the currency exchange rates in effect on the Transfer Date, as 
published in the WALL STREET JOURNAL on the first business day following the 
Transfer Date.

                    (iii)  Within 45 days following the Closing Date, Amtech, 
with the assistance and cooperation of UNOVA, shall prepare and deliver to 
UNOVA a balance sheet of Adjusted TSG as of the Transfer Date (the 
"Preliminary Closing Balance Sheet"), prepared in accordance with 
subparagraph (ii) above. UNOVA shall have 30 days following its receipt of 
the Preliminary Closing Balance Sheet (the "Review Period") to review the 
same for compliance with subparagraph (ii) above.  On or before the 
expiration of the Review Period, UNOVA shall deliver to Amtech a written 
statement accepting or objecting to the Preliminary Closing Balance Sheet.  
In the event that UNOVA shall object to the Preliminary Closing Balance 
Sheet, such statement shall include an itemization of UNOVA's objections and 
its reasons therefor.  If no such statement is delivered by UNOVA to Amtech 
within the Review Period, UNOVA shall be deemed to have accepted the 
Preliminary Closing Balance Sheet.

                    (iv)   In the event that UNOVA shall accept or shall be 
deemed to have accepted the Preliminary Closing Balance Sheet as prepared and 
delivered by Amtech, the Preliminary Closing Balance Sheet shall constitute 
the Final Closing Balance Sheet for purposes of determining the Purchase 
Price.  In the event, however, that UNOVA shall object to the Preliminary 
Closing Balance Sheet, UNOVA and Amtech shall promptly meet and in good faith 
attempt to resolve the issues that are in dispute.  In the event that the 
issues in dispute shall not have been resolved within 30 days following 
Amtech's receipt of UNOVA's statement of objections to the Preliminary 
Closing Balance Sheet, such disputed issues shall be resolved within an 
additional 60 days by Price Waterhouse (the "Independent Firm").  The costs 
and expenses of the Independent Firm in reviewing the issues in dispute shall 
be borne fifty percent (50%) by UNOVA and fifty percent (50%) by Amtech.  The 
Preliminary Closing Balance Sheet, as adjusted to reflect the adjustments 
agreed upon by such Parties or determined in accordance with this Section 
1.7(a)(iv), shall constitute the Final Closing Balance Sheet for purposes of 
determining the Purchase Price.

            (b)    PAYMENT OF ESTIMATED PURCHASE PRICE.  At Closing, (1) 
UNOVA (as agent for Intermec) shall pay to Amtech, by wire transfer of 
immediately available funds to the bank account at FNB - Maryland, Account 
Name: Alex. Brown & Sons, Inc., Account Number 068-876-8-00, for further 
credit to Amtech Corporation, Account Number 231-71008-1-2, ABA Number 
052000113 (the "Amtech Bank Account"), the amount equal to $20,000,000 (the 
"Estimated Non-French Cash Purchase Price"), (2) French Subsidiary shall pay 
to AI, by wire transfer of immediately available funds to an account 
designated by AI in writing within two business days (a "business day" being 
a day on which banks are not authorized or required to close in California or 
Texas) prior to Closing (the "AI Bank Account"), the amount equal to $100,000 
(the

                                       6


<PAGE>

"Estimated French Purchase Price"), which is the Parties' best estimate of 
the French Purchase Price, and (3) UNOVA shall transfer and assign to Amtech 
the UNOVA Shares.  The sum of the Estimated Non-French Cash Purchase Price 
and the UNOVA Shares Value is referred to as the "Estimated Non-French 
Purchase Price," and the sum of the Estimated Non-French Purchase Price, the 
Estimated French Purchase Price and the UNOVA Shares Value is referred to as 
the "Estimated Purchase Price."  It is understood and agreed that the amount 
of cash payable by UNOVA to Amtech and by French Subsidiary to AI at Closing 
shall remain unchanged regardless of whether the UNOVA Shares Value is less 
than, greater than or equal to $10,000,000.  

            (c)     SETTLEMENT OF PURCHASE PRICE.  In the event that the 
Purchase Price (as finally determined pursuant to Section 1.7(a)) is greater 
or less than the Estimated Purchase Price (such excess or deficiency being 
referred to as the "Adjustment"), on or before the third business day 
following the date upon which the Purchase Price is finally determined, the 
Adjustment shall be paid as follows:  (i) If the Non-French Purchase Price is 
greater than the Estimated Non-French Purchase Price, UNOVA shall pay to 
Amtech the excess of the Non-French Purchase Price over the Estimated 
Non-French Purchase Price, plus interest on such amount from the Closing Date 
to the date of payment at the rate of six percent (6%) per annum ("Purchase 
Price Adjustment Interest Rate"); (ii) If the French Purchase Price is 
greater than the Estimated French Purchase Price, French Subsidiary shall pay 
to AI the excess of the French Purchase Price over the Estimated French 
Purchase Price, plus interest on such amount from the Closing Date to the 
date of payment at the Purchase Price Adjustment Interest Rate; (iii) if the 
Non-French Purchase Price is less than the Estimated Non-French Purchase 
Price, Amtech shall pay to UNOVA the excess of the Estimated Non-French 
Purchase Price over the Non-French Purchase Price, plus interest on such 
amount from the Closing Date to the date of payment at the Purchase Price

the Estimated French Purchase Price, AI shall pay to French Subsidiary the

may be necessary to effect the valid sale, transfer or assignment of the same 
to French Subsidiary without change in any of the material terms or 
conditions thereof, including without limitation the formal assignment or 
novation of any of the same, if so required.  AI and French Subsidiary 
further covenant and agree to make or complete such transfers as soon as 
reasonably possible and to cooperate with each other in any other reasonable 
arrangement designed to provide for French Subsidiary the benefits of and the 
obligations under such properties, rights or assets, including without 
limitation enforcement for the benefit of French Subsidiary of any and all 
rights of AI against the other party thereto arising out of the breach or 
cancellation thereof by such other party or otherwise.

to be so qualified would not have a material adverse effect on its business, 
assets, financial condition or results of operations.  To the knowledge of 
Amtech, ACL is a limited liability company duly formed, validly existing and 
in good standing under the laws of its jurisdiction of organization and is

which it is a party and, subject to the conditions provided in this 
Agreement, to consummate the transactions provided for in this Agreement and 
the Related Agreements.  

            (d)     DUE EXECUTION AND ENFORCEABILITY.  The execution, 
delivery and performance by and on behalf of each of the Selling Entities of 
this Agreement and the Related Agreements to which it is a party have been 
duly and validly authorized and approved by its board of directors and 
shareholders, if required, and no other corporate action is necessary or 
required to authorize it to execute this Agreement and such Related 
Agreements and to perform its obligations under this Agreement and such 
Related Agreements.  This Agreement constitutes, and such Related Agreements 
(when executed by the parties to them) will constitute, the valid and legally 
binding obligations of each of the Selling Entities enforceable in accordance 
with their respective terms and conditions, except to the extent the same may 
be limited by bankruptcy, insolvency, reorganization,

to inspect and examine and the right to photocopy all books of account and 
records of the Selling Entities that were retained by the Selling Entities 
pursuant to this Agreement and which relate to the affairs and business of 
TSG conducted on or prior to the Transfer Date; PROVIDED that such

     8.2    FURTHER INSTRUMENTS AND ASSURANCES.  From and after the Closing 
Date, the Parties shall execute and deliver, or cause to be executed and 
delivered, to each other such further instruments and shall take such other

transactions contemplated by this Agreement and the Related Agreements.

     8.3    NONDISCLOSURE BY AMTECH.  Each of the Selling Entities covenants 
and agrees that for a period of four years from and after the Transfer Date, 
it shall hold in confidence (and shall use reasonable efforts to cause its 
officers, directors and Affiliates to hold in confidence) any and all 
proprietary, confidential or secret information or data of the Selling 
Entities in respect of the Business and not to disclose, publish or use the 
same unless (i) such disclosure or publication is required by law or any 
stock exchange or inter-dealer quotation system on which the securities of 
Amtech are traded, (ii) the prior written consent of UNOVA has been obtained, 
or (iii) the same has been theretofore publicly disclosed by any of the 
Buying Entities or otherwise ceased to be secret or confidential as evidenced 
by general public knowledge.

     8.4    LITIGATION COOPERATION.  In the event that any Party shall 
participate in any suit, action, proceeding or investigation concerning the 
Business conducted on or prior to the Transfer Date (excluding any such suit, 
action, proceeding or investigation between Amtech, on the one hand, and 
UNOVA or Intermec, on the other hand), the Parties shall, upon the request of 
the Party involved in such litigation, cooperate fully with such Party at 
such Party's expense in connection therewith, except to the extent that such 
litigation


                                       41


<PAGE>

arises from a breach by any such Party of any representation, warranty, 
covenant or agreement contained in this Agreement and the Related Agreements. 
 
     8.5    CERTAIN EMPLOYEE MATTERS.  

            (a)     EMPLOYMENT AND EMPLOYEE BENEFITS.  Subject to Section 
8.5(d) below, French Subsidiary shall offer employment as of the Closing Date 
to substantially all of the employees of AI.  Those employees who accept such 
offer and all employees of the members of TSG other than AI are referred to 
collectively as the "Continuing Employees."  UNOVA shall credit the 
Continuing Employees with years of continuous service with Amtech for 
purposes of eligibility and vesting under UNOVA's employee benefit plans, to 
the extent permitted under the terms of such plans.  Amtech shall cease 
accrual of benefits with respect to any Continuing Employee  under any of its 
employee benefit plans.  Amtech shall cause all unvested deposits of the 
Continuing Employees in Amtech's 401(k) plan to become vested as of the 
Closing Date. UNOVA shall offer all Continuing Employees the opportunity to 
enroll in UNOVA's 401(k) plan (the "FSSP") subject to the enrollment 
requirements of the FSSP.  As soon as UNOVA shall have reasonably concluded 
that Amtech's 401(k) plan is tax-qualified, it shall cause the FSSP to accept 
the direct rollover of the pre-tax account balance for a Continuing Employee 
under Amtech's 401(k) plan, whether or not such Continuing Employee elects to 
enroll as an active participant in the FSSP.

            (b)     CERTAIN RETAINED RESPONSIBILITY.  AI shall bear and 
discharge any and all liability to any present or former employee of AI 
arising from his or her employment by AI (i) accrued on or prior to the 
Closing Date, except for the Assumed Employee Obligations, or (ii) arising as 
a consequence of the Closing.  Subject to Section 8.5(d) below, Amtech and 
the Remaining Amtech Subsidiaries shall bear and discharge any and all 
liability to each of their former employees arising from his or her 
employment prior to the Closing Date by Amtech or such Acquired Amtech 
Subsidiary.

            (c)     WARN ACT.  The Selling Entities shall comply with the 
applicable provisions of the Worker Adjustment and Retraining Notification 
Act of 1988 (the "WARN Act") and any similar federal, state or local law, if 
any, at all times prior to the Closing Date.  The Buying Entities shall 
comply with the applicable provisions of the WARN Act and any similar 
federal, state or local law, if any, at all times following the Closing Date. 
 
            (d)     CERTAIN SEVERANCE LIABILITY.  In the event that French 
Subsidiary does not offer employment to all of the employees of AI (those to 
whom it does not offer employment are referred to as the "Rejected 
Employees"), UNOVA shall be responsible for the statutory severance payable 
to all Rejected Employees who are full-time, salaried employees on the 
Agreement Date, up to a maximum of nine such Rejected Employees.

     8.6    COLLECTION AND REPURCHASE OF ACCOUNTS RECEIVABLE.  


                                       42


<PAGE>

            (a)     COLLECTION OF ACCOUNTS RECEIVABLE.  On the date of 
delivery of the Preliminary Closing Balance Sheet, Amtech shall deliver to 
Intermec listings of the invoices and the unpaid amount of each and any other 
items making up the total billed accounts receivable included on the 
Preliminary Closing Balance Sheet.  During the 180-day period following the 
Transfer Date (the "Collection Period"), Intermec shall (and shall cause the 
relevant members of TSG to) use the normal collection procedures used in the 
Business (but in no event shall any of them be obligated to file or perfect 
any liens or file or prosecute any suit as part of its collection effort) to 
collect all billed accounts, notes and drafts receivable which are legally 
due under the relevant contract and which will be included in the Final 
Closing Balance Sheet (the "Transfer Date Receivables").  For purposes of the 
foregoing sentence, "legally due under the relevant contract" means the 
amount billed excluding any retention permitted under such contract until the 
conditions of such retention are fulfilled.  Any payments received by 
Intermec or French Subsidiary or any member of TSG from any person who is the 
account debtor on any of the Transfer Date Receivables (a "Customer") shall 
be applied as specified by the Customer, unless it is uncertain which invoice 
is being paid, in which case, payments shall be applied in the order of the 
oldest invoice first.  Amtech shall promptly remit to Intermec any payments 
that it or any of the Remaining Amtech Subsidiaries may receive in respect of 
any of the Transfer Date Receivables.  Intermec and French Subsidiary shall 
(and shall cause the relevant members of TSG to) make and keep detailed 
records of amounts collected in respect of the Transfer Date Receivables 
until such time as the "Uncollected Receivables" (as defined in paragraph (b) 
below) are assigned to Amtech pursuant to paragraph (b) below.

            (b)     REPURCHASE OF ACCOUNTS RECEIVABLE.  Promptly following 
the expiration of the Collection Period, Intermec shall deliver to Amtech a 
statement setting forth (i) a list and description of the Transfer Date 
Receivables that were not collected during the Collection Period (the 
"Uncollected Receivables"), and (ii) a schedule setting forth the calculation 
of the aggregate amount of Uncollected Receivables LESS the reserve provided 
for Uncollected Receivables on the Final Closing Balance Sheet PLUS interest 
on such net amount from the Closing Date to the date of payment to Intermec 
at the Purchase Price Adjustment Interest Rate.  Within 10 business days 
following Amtech's receipt of such statement, Amtech shall pay to Intermec, 
by wire transfer of immediately available funds, the amount of such 
statement, including applicable interest, and upon receipt of such payment, 
Intermec and French Subsidiary shall (and shall cause the relevant members of 
TSG to) assign without recourse the Uncollected Receivables to Amtech.  
Following such assignment, (i) Intermec and French Subsidiary shall (and 
shall cause the relevant members of TSG to) remit to Amtech any payments it 
shall receive on such Uncollected Receivables, and (ii) Amtech shall consult 
with Intermec prior to instituting any legal proceedings or taking any other 
extraordinary measures to collect the Uncollected Receivables, and if 
requested by Intermec, shall refrain from instituting such legal proceedings 
or taking such other extraordinary measures if Intermec,  French Subsidiary 
or the relevant member of TSG retains or repurchases the Uncollected 
Receivable in question.  

     8.7    CHANGE OF AMTECH NAME.  Within ten business days following the 
Closing 


                                       43


<PAGE>

Date, Amtech shall adopt a fictitious name (the "DBA") that does not include 
"Amtech" or derivations thereof.  Promptly following the Closing Date, Amtech 
shall make all appropriate filings with respect to the DBA in all counties in 
which Amtech or the Remaining Amtech Subsidiaries conduct business under the 
name Amtech.  At the sooner of the first annual meeting of Amtech's 
shareholders held after the Closing Date or August 30, 1998, Amtech shall 
submit to its shareholders a proposal that they approve Amtech's change of 
its corporate name to a name that does not include "Amtech" or derivations 
thereof (the "Corporate Name Change"), and shall recommend approval of such 
proposal. As promptly as practicable after the Closing Date, Amtech shall 
cause each of the Remaining Amtech Subsidiaries whose name includes the word 
"Amtech" to change its corporate name to a name that does not include the 
word "Amtech" or derivations thereof.  From and after the Closing Date, 
Amtech and AI shall (and shall cause the Remaining Amtech Subsidiaries to) 
cease to use the name "Amtech" or "Amtech Corporation" or derivations 
thereof, except (i) as necessary to effect the name changes provided for in 
the foregoing sentence, (ii) in connection with its trading symbol prior to 
the effectiveness of the Corporate Name Change, (iii) in connection with any 
required use of its legal name (rather than the DBA) prior to the 
effectiveness of the Corporate Name Change, and (iv) to use up existing 
stationery, packing, shipping, invoices, purchase orders and similar supplies 
which bear the name "Amtech" for the period necessary to exhaust such 
supplies, but in no event longer than the later of the date of the 
effectiveness of the Corporate Name Change and six months from and after the 
Transfer Date; PROVIDED, HOWEVER, that from and after the tenth business day 
following the Closing Date, Amtech and AI shall (and shall cause the relevant 
Remaining Amtech Subsidiaries to) overprint, overstamp, apply an appropriate 
label or otherwise obliterate the name "Amtech" on such items; and PROVIDED, 
FURTHER, HOWEVER, that from and after the Closing Date, neither Amtech nor AI 
shall (and shall not permit any of the Remaining Amtech Subsidiaries to) 
represent or hold itself out to the public as representing or being 
affiliated with TSG; and PROVIDED, FURTHER, HOWEVER, that Amtech shall 
indemnify, defend and hold harmless the "Buying Interests" from any "Loss" 
(as such terms are defined in Section 11.1) suffered by any of the Buying 
Interests as a result of use of the name "Amtech" (or derivations thereof) 
following the Closing Date.

     8.8    PERFORMANCE BONDS.  UNOVA shall after the Agreement Date use its 
best efforts to substitute effective as of the Closing its credit for the 
credit of Amtech securing the obligations of any member of TSG under any of 
its or their executory contracts (the "Performance Bonds"), including without 
limitation those contracts and agreements set forth on Schedules 3.8(h) and 
(j) but excluding Performance Bonds identified on Schedule 3.8(h) as the 
"Amtech Remaining Guarantees."  Pending such substitution, Amtech shall keep 
the Performance Bonds in full force and effect.  SEE Section 11.2(d) 
regarding indemnification in connection with the Performance Bonds.

     8.9    COLLECTION OF BRAZILIAN NOTES.  As and when payments of principal 
and interest are made to AWC under the Brazilian Notes, Intermec shall cause 
AWC to promptly remit such amounts to Amtech.  At any time after the Closing, 
at the option of Amtech, which shall be exercised, if at all, by giving 
written notice to UNOVA, UNOVA 


                                       44


<PAGE>

shall cause AWC to assign to Amtech or its designee legal title to the 
Brazilian Notes.

     8.10   IMMUNITY FROM INFRINGEMENT.  UNOVA shall not (and shall not 
permit any of its subsidiaries, including the members of TSG following the 
Closing Date, to) sue Amtech or any of the Remaining Amtech Subsidiaries (for 
so long as such Remaining Amtech Subsidiaries are Affiliates of Amtech) for 
infringement of any Intellectual Property presently owned by or assigned to 
any member of TSG or assigned to UNOVA or any of its subsidiaries pursuant to 
this Agreement, to the extent that such infringement is caused by the 
manufacture, use or sale of products of Amtech or the Remaining Amtech 
Subsidiaries, which products exist on the Closing Date.  

     8.11   THAILAND AND BEFIC INVENTORY.  In the event that following the 
Closing Date, any of the Buying Entities or any member of TSG shall sell any 
of the inventories related to the Thailand or BEFIC contracts, which 
inventories shall be fully reserved on the Final Closing Balance Sheet 
pursuant to Section 1.7(a)(ii) and Exhibit A-2, UNOVA shall pay to Amtech an 
amount (the "Inventory Payment") equal to eighty percent (80%) of the "Net 
Proceeds" (as hereinafter defined) of such sale; PROVIDED, HOWEVER, that in 
no event will the Inventory Payment be less than fifty percent (50%) of the 
original inventory value less the "Deductions" (as hereinafter defined).  
"Net Proceeds" shall mean the sales price received less the following (the 
"Deductions"): any selling, general or administrative expenses directly 
related to such inventory, and costs required to be invested in such 
inventory to make it saleable, and any shipping costs. In the event that such 
inventory shall not have been sold prior to December 31, 1999, Amtech will 
have the right until March 31, 2000 to have such inventory delivered to 
Amtech, at its expense.

     8.12   TEXAS RANGERS.  Prior to the conclusion of the 1998 season and 
subsequent to the Closing Date, UNOVA shall be entitled to receive, upon 
request, tickets to the Texas Rangers games and access to Amtech's suite at 
the Ballpark at Arlington up to an aggregate value of $20,000.  UNOVA shall 
have no liability or obligation related to such tickets subsequent to the 
conclusion of the 1998 season.

     8.13   AGREEMENTS REGARDING CERTAIN CONTRACTS.  If any of the Selling 
Entities or any member of TSG expects to incur warranty costs on the 
Thailand, Kansas Turnpike or Georgia 400 contracts, in each case, in excess 
of the amount of the respective warranty reserves provided for such contracts 
on the Final Closing Balance Sheet, UNOVA shall request Amtech's prior 
written consent to incur such costs ("Excess Warranty Costs"), which consent 
shall not be unreasonably withheld or delayed.  Following UNOVA's receipt of 
such consent by Amtech, such Selling Entity or member of TSG may incur such 
Excess Warranty Costs, and Amtech shall pay to UNOVA the amount of such 
Excess Warranty Costs actually incurred by such Selling Entity or member of 
TSG.   Separately, if the Thailand customer pays for, or returns, all or a 
portion of the 10,100 tags advanced to it by Amtech, UNOVA shall remit to 
Amtech the gross profit or inventory value on such tags up to a maximum 
payment of $100,000.

                                          
                                 (Article 9 follows)

suffered such Loss or received such notice of such Third Party Claim and who 
shall seek indemnification in respect thereof (the "Indemnified Party") shall 
give Amtech or UNOVA, as the case may be (the "Indemnifying Party"), prompt

                                       53


<PAGE>

            In the case of Third Party Claims, written notice thereof shall 
be given to the Indemnifying Party as promptly as practicable; PROVIDED, 
HOWEVER, that the failure of any Indemnified Party to give timely notice 
shall not affect rights to indemnification hereunder if (i) such failure to 
give timely notice does not materially affect the ability or right of the 
Indemnifying Party to defend such Third Party Claim and the Indemnifying 
Party is not otherwise materially prejudiced thereby, and (ii) actual notice 
is given to the Indemnifying Party within a reasonable time.

            The Indemnifying Party shall have 30 days from the date of 
receipt of said notice (the "Investigation Period") to investigate and 
dispute the nature, validity or amount of any such claim of Loss or Third 
Party Claim. During the Investigation Period, the Indemnified Party shall 
cooperate with the Indemnifying Party for the purpose of such investigation 
and, without limitation, the Indemnified Party shall make available to the 
Indemnifying Party the information relied upon by the Indemnified Party to 
substantiate the Indemnified Party's claim, and the Indemnifying Party shall 
have reasonable access, during normal business hours, to the books, records 
and other documents of the Indemnified Party relating to such claim and shall 
have the right to take copies at its expense of such relevant books, records 
and documents for the purpose of such investigation.  In the event that the 
Indemnifying Party shall dispute the nature, validity or amount of a claim 
hereunder, the Indemnifying Party shall give the Indemnified Party written 
notice of such dispute within the Investigation Period, and the relevant 
Parties shall meet promptly thereafter and in good faith attempt to resolve 
such dispute.  To the extent that such Parties cannot resolve any dispute by 
agreement within 21 days following such notice of dispute, such dispute shall 
be resolved pursuant to Section 12.15.

            In the absence of a dispute, the Indemnifying Party shall 
promptly, and in any event not later than the expiration of the Investigation 
Period, reimburse the Indemnified Party in full for such Loss, as set forth 
in the notice.  In the event that the Indemnifying Party shall dispute only 
the amount (and not the validity) of the claim, the Indemnifying Party shall, 
concurrently with the delivery of its notice of dispute, pay to the 
Indemnified Party any undisputed portion of the claim.  

     11.4   DEFENSE AND SETTLEMENT OF THIRD-PARTY CLAIMS.  In the event of a 
Third Party Claim, if the Indemnifying Party acknowledges that, as between it 
and the Indemnified Party, it is obligated to indemnify the Indemnified Party 
in connection with such Third Party Claim, then such Indemnifying Party shall 
have the option to take control of the defense and investigation of such 
Third Party Claim, and to employ and engage attorneys of its own choice to 
handle and defend the same, at the Indemnifying Party's sole cost, risk and 
expense (the "Direct Litigation Option").  The Indemnifying Party may elect 
to exercise the Direct Litigation Option by giving prior written notice to 
the Indemnified Party.  If the Indemnifying Party so elects, the Indemnified 
Party shall cooperate in all reasonable respects with the Indemnifying Party 
and such attorneys in the investigation, trial and defense of such Third 
Party Claim and any appeal arising therefrom and shall permit access to the 
personnel of the Indemnified Party and to any relevant books, records and 
documents within the possession or control of Indemnified Party in 


                                       54


<PAGE>

connection with such claim and to take copies of such relevant materials at 
the expense of the Indemnifying Party; PROVIDED, HOWEVER, that the 
Indemnified Party may, at its own cost, participate in (but not control) such 
investigation, trial and defense of such Third Party Claim and any appeal 
arising therefrom.  If the Indemnifying Party does not elect the Direct 
Litigation Option, then the Indemnified Party shall defend against the Third 
Party Claim in the manner it deems appropriate.

            The Indemnifying Party may settle a Third Party Claim upon 30 
days prior written notice (the "Settlement Review Period") to the other 
Party, and such settlement shall be binding upon all the Parties; PROVIDED, 
HOWEVER, that except as otherwise provided with respect to an unauthorized 
"Non-Monetary Settlement" (as defined below in this Section 11.4), if within 
the Settlement Review Period the Indemnified Party shall have objected to 
such settlement, the Indemnifying Party shall either, at the election of the 
Indemnified Party:  (i) contest the claim at the expense of the Indemnified 
Party (provided the Indemnified Party shall advance to the Indemnifying Party 
such expenses as may subsequently be incurred), or (ii) permit the 
Indemnified Party to defend the claim on its behalf and at its expense 
provided that the Indemnified Party shall keep the Indemnifying Party advised 
on a timely basis of all developments with respect to such claim and permit 
the Indemnifying Party to participate, at its election and expense, in the 
defense of such claim.  Upon the resolution of a Third Party Claim a proposed 
settlement of which the Indemnified Party shall have rejected as provided in 
this paragraph (a "Rejected Settlement"), the Indemnifying Party's 
responsibility with respect to such claim shall be limited to the amount of 
the proposed settlement plus all costs and expenses incurred in connection 
with the defense of such Third Party Claim on or prior to the date on which 
the Rejected Settlement was rejected by the Indemnified Party.

            Any settlement or finally determined claim resulting from such 
contest which is made in accordance with this Section 11.4, together with the 
total expenses of such contest, shall be binding on the Parties for purposes 
of this Agreement.  

            Notwithstanding anything to the contrary contained in this 
Section 11.4, the Indemnifying Party shall not, without the prior written 
consent of the Indemnified Party, consent to the entry of any judgment or 
enter into any settlement that (a) provides for non-monetary relief binding 
on the Indemnified Party or (b) does not include an unconditional and 
complete release of the Indemnified Party by the claimant (a "Non-Monetary 
Settlement").  In the event that a Non-Monetary Settlement is proposed by the 
Indemnifying Party and the Indemnified Party does not consent thereto, the 
Indemnifying Party shall continue to be responsible for the full amount of 
the costs, expenses and any settlement or judgment with respect to such Third 
Party Claim in accordance with this Article 11. 

     11.5   LIMITATIONS ON INDEMNIFICATION.  

            (a)     DURATION.  Claims for indemnification under Section 11.1 
or 11.2 must be made, if at all, prior to December 31, 2000 (the "Indemnity

and Breach of Warranty), to the extent it is based on a breach of Section 3.5 
(Mortgages, Security Interests, Liens, and Other Encumbrances of Title), 
11.1(b) (Breach of Covenant or Agreement) and 11.1(f) (Unassumed 
Liabilities), to the extent it is based on an Unassumed Liability described 
in paragraphs (a), (b), (d), (e), (f), (g), (i), (k), (n) or (o) of Section 
1.9 (the "Absolute Unassumed Liabilities"), which may be made at any time 
prior to the tenth anniversary of the Transfer Date, and claims pursuant to 
Section 11.1(c) (Taxes), which may be made at any time prior to the 
expiration of the applicable statute of limitations.  Indemnification 
pursuant to Section 11.1 or 11.2 shall be payable after the expiration of the 
Indemnity Period, so long as the claim was identified and asserted in 
reasonable detail prior to such expiration.  No claims for indemnification 
(except as aforesaid) may be made after the expiration of the Indemnity
