            The Schedule 13D dated March 30, 1996 (the "Schedule  13D") filed in
connection  with (i) the  purchase of 2,000,000  Class B Cumulative  Convertible
Preferred  Shares,  $.01  par  value  (the  "Class  B  Preferred  Shares"),   of
Dynamotion/ATI Corp., a New York corporation  ("Dynamotion/ATI"),  by Dynamotion
Investment   L.L.C.,  a  New  Jersey  limited  liability  company   ("Dynamotion
Investment"),  and (ii) the issuance by Dynamotion/ATI to Dynamotion  Investment
of a  Warrant,  dated  March 20,  1996 (the  "Warrant"),  exercisable  for up to
330,302  shares of  Common  Stock,  $.04 par  value  (the  "Common  Stock"),  of
Dynamotion/ATI  at a purchase  price of $1.009178  per share is being amended as
set forth below.  All  capitalized  terms used without  definition in this Final
Amendment to the Schedule 13D have the meanings set forth in the Schedule 13D.

            1.     The  responses  to  Items 3, 4, 5 and 6 are hereby amended by
adding the following:

            As of January 24, 1997,  Dynamotion/ATI,  Dynamotion  Investment and
certain  other  shareholders  of  Dynamotion/ATI  entered  into an  Agreement of
Reorganization   and  Merger,   dated  as  of  January  24,  1997  (the  "Merger
Agreement"),  with Electro  Scientific  Industries,  Inc., an Oregon corporation
("ESI"),  and Dynamotion Merger Corp., a New York corporation  ("Merger Corp.").
Under the Merger Agreement,  Dynamotion Investment incurred certain obligations,
including an obligation  to exercise the Warrant  before the record date for the
special  meeting  of  the  shareholders  of  Dynamotion/ATI  to  vote  upon  the
transactions  contemplated by the Merger  Agreement (the "Special  Meeting").  A
copy of the Merger Agreement is attached hereto as Exhibit I and is incorporated
by reference herein in its entirety.

            In  accordance  with that  covenant,  on April 4,  1997,  Dynamotion
Investment exercised the Warrant in full and paid an aggregate purchase price of
$333,340.78  for 330,302 shares of Common Stock.  Those funds were obtained from
the  members  of  Dynamotion  Investment  who  contributed  them  to  Dynamotion
Investment for that purpose. To the knowledge of Dynamotion Investment,  none of
its members borrowed any portion of those funds. The acquisition of those shares
of Common  Stock upon  exercise  of the Warrant did not change the amount of the
Common Stock of Dynamotion/ATI beneficially owned by Dynamotion Investment, only
the form of ownership.

            Also, as of January 24, 1997,  Dynamotion  Investment entered into a
Voting Agreement (the "Voting  Agreement") with ESI pursuant to which Dynamotion
Investment  agreed to vote at the  Special  Meeting  all of its shares of Common
Stock and Class B Preferred Shares to approve the merger of Dynamotion/ATI  with
and into Merger Corp.  (the  "Merger") the Merger  Agreement and a proposal (the
"Conversion  Proposal")  to (i)  amend  the  terms  of the  outstanding  Class B
Preferred  Shares so that such  Class B  Preferred  Shares  would  automatically
convert  into shares of Common  Stock  immediately  before the Merger would take
effect; and (ii) amend the terms of Dynamotion/ATI's outstanding Class A Non-

                             Page 3 of 6 Pages

<PAGE>

Cumulative Redeemable Convertible Preferred Shares, $.01 par value, so that such
shares  would  automatically  convert  into  shares  of  Common  Stock  and cash
immediately  before the Merger would take effect. A copy of the Voting Agreement
is attached hereto as Exhibit J and is  incorporated by reference  herein in its
entirety.

            At the Special Meeting,  which was held on May 23, 1997, the Merger,
the Merger Agreement and the Conversion Proposal were approved by the holders of
the  requisite  percentages  of the  outstanding  shares  of  capital  stock  of
Dynamotion/ATI.  On  June  9,  1997  (the  "Effective  Time"),  the  Merger  was
consummated. Immediately prior thereto, all outstanding Class B Preferred Shares
owned by Dynamotion Investment were converted into shares of Common Stock. Those
shares of Common  Stock and the shares of Common  Stock  acquired by  Dynamotion
Investment  upon  exercising  the Warrant were  converted in the Merger into the
right to receive shares of Common Stock, no par value ("ESI Common  Stock"),  of
ESI  (and  cash in lieu of any  fractional  share).  As of the  Effective  Time,
Dynamotion  Investment  ceased to  beneficially  own any  equity  securities  of
Dynamotion/ATI.

            2.    The  responses  to  Items 4 and 6 are hereby amended by adding
the following:

            In November,  1996,  the terms of the Class B Preferred  Shares were
amended (i) to eliminate the right of the holders  thereof to sell any or all of
those  shares to  Dynamotion/ATI  after March 20, 2001 and (ii) to increase  the
dividend  rate  on the  Class B  Preferred  Shares  after  that  date in  yearly
increments of $.01 per share to $.20 per share.

            Pursuant  to the  Merger  Agreement,  in the  Merger,  each share of
Common Stock  outstanding  immediately prior to the Effective Time was converted
into the right to  receive a  fraction  of a share of ESI  Common  Stock,  which
fraction was  determined in accordance  with the formula set forth in the Merger
Agreement.  From and after the Effective Time, (i) the articles of incorporation
and bylaws of Merger Corp. in effect  immediately  preceding the Effective  Time
continued in effect and (ii) the directors and officers of Merger Corp. remained
in such offices and, as a result, two members of Dynamotion Investment ceased to
be  directors  of  Dynamotion/ATI.  A copy of the Merger  Agreement  is attached
hereto as Exhibit I and is incorporated by reference herein in its entirety.

            Consummation  of  the   transactions   contemplated  by  the  Merger
Agreement was subject to the  satisfaction  of the  conditions  contained in the
Merger Agreement,  including the agreement of Dynamotion Investment to terminate
certain  agreements with  Dynamotion/ATI  and to execute certain agreements with
ESI. In addition,  in the Merger Agreement,  Dynamotion  Investment made certain
representations  and  warranties  to ESI,  primarily  concerning  its ability to
perform its obligations thereunder.

            As of the Effective Time, in accordance  with the Merger  Agreement,
Dynamotion  Investment  terminated all of its rights under all of its agreements
with  Dynamotion/ATI,   including  the  Purchase  Agreement,   the  Registration
Agreement and the Letter Agreement and Emptor terminated all of its rights under
the  Consulting  Agreement.  As  required  by the Merger  Agreement,  Dynamotion
Investment  has agreed to place in an escrow  account  some of the shares of ESI
Common Stock it received in the Merger in connection with  satisfying  potential
indemnification  obligations that certain Dynamotion/ATI shareholders (including
Dynamotion  Investment)  may  have to ESI and to hold all of its  shares  of ESI
Common Stock for at least one year from the Effective Time.

         Pursuant to the terms of the Voting Agreement,  at the Special Meeting,
Dynamotion  Investment  voted  all of its  shares  of  Common  Stock and Class B
Preferred Shares in favor of approving the Conversion  Proposal,  the Merger and
the Merger  Agreement.  A copy of the Voting  Agreement  is  attached  hereto as
Exhibit J and is incorporated by reference herein in its entirety.

            3.    The response to Item 7 is hereby amended as
follows:

            I     Agreement of Reorganization and Merger among
                  Electro Scientific Industries, Inc.,
                  Dynamotion/ATI Corp., Dynamotion Merger Corp. and
                  Certain Key Shareholders of Dynamotion/ATI Corp.,
                  dated as of January 24, 1997.

            J     Voting Agreement dated as of January 24, 1997
                  between Electro Scientific Industries, Inc. and
                  Dynamotion Investments, L.L.C.

AGREEMENT

OF

REORGANIZATION AND MERGER


      THIS AGREEMENT OF REORGANIZATION  AND MERGER (this "Agreement") is entered
into as of January 24, 1997 among Electro Scientific Industries, Inc., an Oregon
corporation   ("ESI"),    Dynamotion/ATI   Corp.,   a   New   York   corporation
("Dynamotion"),  Dynamotion  Merger  Corp.,  a  New  York  corporation  ("Merger
Corp."),  and the shareholders of Dynamotion  listed on Schedule A (each, a "Key
Shareholder" and together, the "Key Shareholders").

      RECITALS

      A. The Boards of Directors of ESI and Dynamotion  have  determined that it
is in the best  interests of their  respective  shareholders  for ESI to acquire
Dynamotion  upon the  terms  and  subject  to the  conditions  set forth in this
Agreement.
      B. It is  intended  that  the  Merger  (as  defined  below)  qualify  as a
reorganization  under the  provisions  of Section  368(a) of the  United  States
Internal Revenue Code of 1986, as amended (the "Code").
      C. It is further  intended that certain rights relating to the acquisition
of, or conversion of securities into, the common stock or other capital stock of
Dynamotion  (including certain warrants and convertible preferred stock) will be
exercised,  converted,  or redeemed according to their respective terms, or will
be terminated, before the consummation of the Merger.

      AGREEMENT

      In consideration of the representations, warranties, covenants, agreements
and conditions contained herein, the parties agree as follows:

      ARTICLE I
      THE MERGER

      1.1 The Merger. Pursuant to the laws of the State of New York, and subject
to and in accordance  with the terms and  conditions  of this  Agreement and the
Plan of Merger in the form attached  hereto as Exhibit A (the "Plan of Merger"),
Dynamotion  will be merged with and into Merger Corp.,  and all shares of Common
Stock of Dynamotion,  $0.04 per share par value (the "Dynamotion Common Stock"),
outstanding immediately before the Effective Time (as defined below),  excluding
Dissenting  Shares (as defined in Section  1.5.2),  will be  converted  into the
right to  receive  shares of Common  Stock of ESI,  without  par value (the "ESI
Common Stock"), or cash, as provided in Section 1.3. Dynamotion and Merger Corp.
will execute a Certificate  of Merger to be filed by the  Department of State of
the State of New York on the Closing Date (as defined in Section 1.7) or as soon
thereafter as  practicable.  The merger of Dynamotion with and into Merger Corp.
(the  "Merger")  will take  effect (the  "Effective  Time") at the time when the
Certificate  of Merger is duly filed by the  Department of State of the State of
New York or at such other time as the parties may agree upon in writing pursuant
to applicable law.

      1.2 Effect of Merger.  At the Effective  Time,  Dynamotion  will be merged
with and into Merger Corp. in the manner and with the effect provided by the New
York Business Corporation Law (the "NYBCL"), the separate corporate existence of
Dynamotion will cease,

                               - 2 -

<PAGE>


and Merger Corp. will be the surviving corporation. From and after the Effective
Time, the Certificate of Incorporation, Bylaws, Board of Directors, and officers
of Merger Corp. in effect or in office, as the case may be,  immediately  before
the Effective Time will be the Certificate of  Incorporation,  Bylaws,  Board of
Directors,  and officers of the surviving corporation;  provided,  however, that
the Certificate of Incorporation of the surviving corporation will be amended to
effect the name change described in this Section 1.2. The outstanding  shares of
Dynamotion  Common Stock will be converted  into the right to receive  shares of
ESI Common Stock or cash on the basis, terms and conditions described in Section
1.3. At the Effective  Time, the name of the surviving  corporation  will become
Dynamotion, Inc.
      1.3  Merger   Consideration.   Each  share  of  Dynamotion   Common  Stock
outstanding  immediately  before the Effective Time  (excluding  each Dissenting
Share) will be converted  into the right to receive a fraction of a share of ESI
Common  Stock  (or cash in lieu of  certain  fractional  shares as  provided  in
Section 1.4.3) (such ESI Common Stock and/or cash,  the "Merger  Consideration")
that  equals the ratio  (the  "Conversion  Ratio,"  which will be rounded to the
nearest .0001 of a share)  determined by dividing the Conversion Ratio Numerator
by the Conversion Ratio Denominator where:
           (a)  the  "Conversion  Ratio  Numerator"  will  be  the  quotient  of
$13,000,000  divided by the  per-share  price for ESI Common  Stock equal to the
average of the high and low sales  prices  for ESI  Common  Stock on each of the
five  trading  days  immediately  preceding  the day before the Closing  Date as
reported in The Wall Street Journal (such price, the "Average Sale Price");

                               - 3 -

<PAGE>


           (b) the "Conversion Ratio Denominator" will be equal to the number of
shares of Dynamotion Common Stock outstanding  immediately  before the Effective
Time  (including all shares of Dynamotion  Common Stock deemed to be outstanding
upon the effectiveness of the conversion contemplated by the Conversion Proposal
(as that term is defined  in Section  4.2.6)  immediately  before the  Effective
Time) plus the number of shares of  Dynamotion  Common  Stock that are  issuable
upon the  exercise  of Z Warrants  for which  holders  of Z Warrants  have given
exercise  notices by 5:00 p.m.,  New York time,  on the Closing Date (which date
will also be the "Redemption  Date," as that term is defined in the Z Warrants).
As used herein,  the term "Z Warrants"  means all warrants to purchase shares of
Dynamotion  Common Stock issued upon the  conversion  of Class A  Non-Cumulative
Redeemable Convertible Preferred Shares of Dynamotion, $0.01 per share par value
(such shares, the "Class A Stock").

           1.3.1 Dynamotion Stock. Each share of Dynamotion Common Stock that is
outstanding  immediately  before the Effective Time and that is not a Dissenting
Share  will,  by virtue of the Merger and  without any action on the part of the
holder  thereof,  cease to exist and be converted  into the right to receive the
Merger Consideration.

           1.3.2 Merger Corp. Stock.  Each share of Common Stock of Merger Corp.
issued and   outstanding immediately before the Effective Time will remain 
outstanding without change by virtue of the Merger.

           1.3.3 Options. Dynamotion's 1991 Stock Option Plan, Dynamotion's 1993
Stock  Option  Plan,   Dynamotion's  1995   Comprehensive   Stock  Option  Plan,
Dynamotion's  1995 Executive Stock Option Plan, and the stock option  agreements
listed on Schedule  1.3.3  between  Dynamotion  and  certain  current and former
officers and directors of Dynamotion are referred

                               - 4 -

<PAGE>

to herein  together  as the  "Dynamotion  Option  Plans."  Except  as  otherwise
provided in this Section  1.3.3,  the terms and  provisions of the stock options
held by those Dynamotion option holders identified in Schedule 3.1.2.2 under the
Dynamotion  Option Plans (the  "Options") will continue in full force and effect
following  the Merger.  By virtue of the Merger and at the Effective  Time,  and
without any further action on the part of any holder  thereof,  each Option will
be converted into an option to purchase the number of shares of ESI Common Stock
equal to the product  (rounded to the nearest whole number) of (x) the number of
shares of  Dynamotion  Common  Stock for which such Option  will be  exercisable
immediately  before the Effective Time  multiplied by (y) the Conversion  Ratio.
The exercise  price per share for each Option after the  Effective  Time will be
determined by dividing the per share exercise price for such Option  immediately
before the Effective Time by the  Conversion  Ratio.  The term,  exercisability,
vesting  schedule,  status as an incentive stock option under Section 422 of the
Code, if  applicable,  and all other terms and conditions of each Option will to
the extent permitted by law and otherwise  reasonably  practicable be unchanged.
Notwithstanding  the  foregoing,  the terms of each Option that is an  incentive
stock option under Section 422 of the Code will be adjusted in  accordance  with
the  requirements  of  Section  425(a)  of the  Code so as not to  constitute  a
modification, renewal, or extension of such Option within the meaning of Section
424 of the Code. An optionee's  continuous employment with Dynamotion before the
Effective Time will be given credit for purposes of the vesting of the number of
shares of ESI Common Stock subject to exercise under such  optionee's  converted
Option after the Effective Time.

      1.4  Surrender and Cancellation of Certificates.

           1.4.1  Surrender of  Certificates.  After the  Effective  Time,  each
holder of shares of Dynamotion Common Stock outstanding  immediately  before the
Effective  Time (other than  Dissenting  Shares),  upon  surrender to ESI or its
agent  designated  for such purpose of a certificate  or  certificates  formerly
representing  such shares (or a certificate for shares of Class A Stock or Class
B Cumulative  Convertible  Preferred  Shares of Dynamotion,  $0.01 per share par
value  ("Class B Stock"),  that have been  converted  into shares of  Dynamotion
Common Stock  pursuant to the  Conversion  Proposal) will be entitled to receive
(a) a  certificate  representing  the number of shares of ESI Common  Stock into
which such shares of Dynamotion Common Stock have been converted pursuant to the
provisions of Section 1.3 less, in the case of each Key Shareholder,  the number
of such shares  determined  to be Escrowed  Property (as defined in Section 6.3)
and (b) subject to Section 6.3 and the  provisions  of the Escrow  Agreement (as
defined in Section  2.2), a  certificate  representing  the shares of ESI Common
Stock determined to be Escrowed  Property.  If any certificate for shares of ESI
Common Stock is to be issued in a name other than that in which the  certificate
surrendered in exchange  therefor is  registered,  it will be a condition of the
issuance  thereof that the  certificate so surrendered be properly  endorsed and
otherwise  in proper  form for  transfer  and that the  person  requesting  such
exchange  pay to ESI or its agent  designated  for such  purpose any transfer or
other taxes required or establish to the reasonable  satisfaction  of ESI or its
agent that such tax has been paid or is not payable.  If any holder of shares of
Dynamotion  Common Stock canceled and retired in accordance  with this Agreement
is unable to deliver a certificate  or  certificates  representing  such shares,
ESI, in the absence of actual notice that any shares theretofore  represented by
any such

                               - 6 -

<PAGE>



certificate  have been acquired by a bona fide  purchaser,  will deliver to such
holder the number of shares of ESI Common Stock to which such holder is entitled
in accordance with the provisions of this Agreement upon the presentation of the
following:  (i) evidence reasonably  satisfactory to ESI (1) that such person is
the owner of the shares theretofore  represented by each certificate  claimed by
him or her to be lost,  wrongfully taken, or destroyed and (2) that he or she is
the person  who would be  entitled  to present  such  certificate  for  exchange
pursuant  to this  Agreement;  and (ii) such  security  or  indemnity  as may be
reasonably  requested  by ESI to indemnify  and hold ESI and its transfer  agent
harmless with respect to such exchange.

           1.4.2 Option Agreements.  After the Effective Time, each holder of an
Option outstanding  immediately before the Effective Time will be deemed to hold
an option  exercisable for ESI Common Stock in accordance with the provisions of
Section 1.3.3.

           1.4.3 No  Fractional  Shares.  No  certificates  or scrip  evidencing
fractional  shares of ESI Common  Stock will be issued in the  Merger,  and such
fractional share interests will not entitle the owner thereof to any rights as a
shareholder  of ESI. In lieu of a fractional  share,  ESI will pay any holder of
shares of Dynamotion  Common Stock who would  otherwise  have been entitled to a
fraction  of a share of ESI Common  Stock  upon  surrender  of the  certificates
therefor an amount of cash (without interest)  determined by multiplying (a) the
Average Sale Price by (b) the  fractional  share interest in ESI Common Stock to
which such holder would  otherwise be entitled.  The  provisions of this Section
1.4.3 will apply to the aggregate  number of shares of  Dynamotion  Common Stock
held  by  each  holder  thereof  and  each  such  holder  will  be  required  to
simultaneously surrender all certificates relating to shares of

                               - 7 -

<PAGE>


Dynamotion Common Stock held by such holder in accordance with the provisions of
Section 1.4 in order to surrender any such certificate.

           1.4.4  Cancellation.  At the Effective  Time all shares of Dynamotion
Common Stock will no longer be outstanding  and will  automatically  be canceled
and retired and will cease to exist, and each certificate  previously evidencing
any such shares of Dynamotion  Common Stock (and each  certificate  representing
shares of Class A Stock or Class B Stock that have been converted into shares of
Dynamotion Common Stock) will thereafter represent only the right to receive the
Merger  Consideration in accordance with the terms of this Agreement;  provided,
however,  that  in  the  case  of  Dissenting  Shares,  such  certificates  will
thereafter  represent  only the right to receive  such  consideration  as may be
determined  to be  due  under  the  NYBCL.  The  holders  of  such  certificates
previously  evidencing  such  shares  of  Dynamotion  Common  Stock  outstanding
immediately before the Effective Time will cease to have any rights with respect
to such shares of Dynamotion Common Stock, except as provided in this Agreement.

           1.4.5  Treasury  Shares.   At  the  Effective  Time,  each  share  of
Dynamotion  Common Stock or other Dynamotion  capital stock held in the treasury
of  Dynamotion  immediately  before  the  Effective  Time will be  canceled  and
extinguished  without any  conversion  thereof and no payment  will be made with
respect thereto.

           1.4.6  Escheat.  Neither ESI nor Merger  Corp.  will be liable to any
holder of shares of  Dynamotion  Common Stock for any shares of ESI Common Stock
(or  dividends or  distributions  with respect  thereto) or cash  delivered to a
public  official  pursuant to any applicable  abandoned  property,  escheat,  or
similar law.

<PAGE>


           1.4.7 Withholding Rights. ESI will be entitled to deduct and withhold
from  the  aggregate   Merger   Consideration   deliverable  to  any  Dynamotion
shareholder  such  amounts as ESI may be  required to deduct and  withhold  with
respect  to the  making  of such  delivery  under  the  Code  or any  applicable
provision of state, local, or foreign tax law. To the extent that amounts are so
withheld by ESI, such withheld  amounts will be treated for all purposes of this
Agreement  as having been  delivered  to the holder of the shares of  Dynamotion
Common Stock in respect of which such deduction and withholding was made by ESI.

      1.5  Dissenters' Rights.

           1.5.1 Notice.  Dynamotion  shareholders  desiring to dissent from the
Merger and obtain payment of the fair value of their shares of Dynamotion Common
Stock (such fair value to be determined as of the day before the special meeting
of Dynamotion  shareholders  called in accordance  with Section 4.2.4 to approve
the Merger and related  transactions  (the  "Special  Meeting"))  in lieu of the
Merger  Consideration may exercise their dissenters' rights under the provisions
of  Sections  910  and  623 of  the  NYBCL  ("Dissenters'  Rights").  The  Proxy
Statement/  Prospectus  (as that  term is  defined  in  Section  4.2.4)  sent by
Dynamotion to its  shareholders  in accordance with Section 4.2.4 will include a
notice  complying with the provisions of Section 605 of the NYBCL concerning the
rights  of  shareholders  to  exercise  Dissenters'  Rights  and a  copy  of the
provisions of Section 623 of the NYBCL.  The notice of  Dissenters'  Rights will
state that written  objection to the Merger must be received by Dynamotion at or
before the Special Meeting as provided in Section 623(a) of the NYBCL.

           1.5.2 Rights of Dissenting Shares.  Shares of Dynamotion Common Stock
that are  issued  and  outstanding as  of  the  Effective  Time  and held by any
shareholder who has, in

                               - 9 -

<PAGE>

accordance with Sections 910 and 623 of the NYBCL, delivered a written notice of
objection  and  payment  demand   accompanied  by  the  required   certification
("Dissenting Shares") will not be converted as described in Section 1.3 but will
from and after the  Effective  Time  represent  only the right to  receive  such
consideration  as may be determined to be due under the NYBCL.  Dynamotion  will
give ESI prompt notice upon receipt by Dynamotion of any payment demand from any
such  shareholder of Dynamotion (a "Dissenting  Shareholder").  Dynamotion  will
not,  before the Effective  Time,  except with the prior written  consent of ESI
(which consent will not unreasonably be withheld),  voluntarily make any payment
with  respect  to, or settle or offer to settle,  any  request  pursuant  to the
exercise  of  Dissenters'  Rights.  Each  Dissenting   Shareholder  who  becomes
entitled,  pursuant  to the NYBCL,  to payment for his,  her, or its  Dissenting
Shares  will   receive   payment   therefor  in   accordance   with  the  NYBCL.
Notwithstanding the foregoing, if any Dissenting Shareholder rescinds,  fails to
perfect,  or  otherwise  loses  Dissenters'  Rights  either  before or after the
Effective Time,  such  shareholder's  shares of Dynamotion  Common Stock will be
converted  into the  right  to  receive  ESI  Common  Stock  or cash,  as of the
Effective Time, in accordance with the provisions of this Agreement.
      1.6 Stock Transfer  Books. At the Effective Time, the stock transfer books
of  Dynamotion  will be closed  and there  will be no  further  registration  of
transfers of  Dynamotion  capital  stock or other  securities  thereafter on the
records of  Dynamotion.  At or after the Effective  Time, any  certificates  for
Dynamotion Common Stock,  Class A Stock, or Class B Stock (other than Dissenting
Shares)  presented to ESI or its agent for any reason will be converted into the
right to receive the Merger  Consideration  in accordance with the provisions of
this Agreement.

                              - 10 -

will be the day on which the last of the  conditions  set forth in Article V has
been fulfilled or waived (other than those  conditions that, by their terms, are
to be satisfied at the Closing).

      1.8 Subsequent  Actions.  If, at any time after the Effective Time, Merger
Corp.  considers  or is  advised  that any  deeds,  bills of sale,  assignments,
assurances,  or any other  actions or things are necessary or desirable to vest,
perfect,  or confirm of record or otherwise in Merger Corp. its right, title, or
interest in, to, or under any of the rights, properties, or assets of Dynamotion
acquired  or to be  acquired by Merger  Corp.  as a result of, or in  connection
with,  the Merger or  otherwise  to carry out this  Agreement,  the officers and
directors of Merger Corp. will be authorized to execute and deliver, in the name
and on  behalf of  Dynamotion,  or  otherwise,  all such  deeds,  bills of sale,
assignments,  and  assurances,  and to take and do, in the name and on behalf of
Dynamotion,  or otherwise, all such other actions and things as may be necessary
or desirable to vest, perfect, or confirm any and all right, title, and interest
in,  to,  and under  such  rights,  properties,  or assets  in Merger  Corp.  or

           3.1.2 Capitalization.

                3.1.2.1 Capital  Structure.  The capital structure of Dynamotion
as of January 15, 1997 is as stated on Schedule 3.1.2.1. Schedule 3.1.2.1 shows:
(a) the number of shares of Dynamotion Common Stock, (b) the number of shares of
Class A Stock,  (c) the  number of  shares  of Class B Stock,  and (d) all other
rights  of any  character  relating  to the  acquisition  of, or  conversion  of
securities into,  Dynamotion Common Stock (including all warrants,  options, and
convertible  debt),  in each case  outstanding as of January 15, 1997 (the items
described  in  (b),  (c),  and  (d)  are  referred  to  herein  together  as the
"Dynamotion Common Stock Equivalent Securities," and all Dynamotion Common Stock
and  Dynamotion  Common  Stock  Equivalent  Securities  are  referred  to herein
together as the  "Dynamotion  Outstanding  Securities").  Schedule  3.1.2.1 also
shows as of January 15, 1997 the corresponding  "Common Stock Equivalent," which
is the  total  number  of  shares  of  Dynamotion  Common  Stock  that  would be
outstanding if all outstanding  Dynamotion Common Stock Equivalent Securities of
that type were converted or exercised according to their terms, for each type of
Dynamotion  Common Stock  Equivalent  Security listed on Schedule  3.1.2.1.  The
"Adjusted  Dynamotion  Common Stock Total," which is the sum of all  outstanding
Dynamotion  Common  Stock  plus  all  Common  Stock   Equivalents   combined  is
11,170,848.  All  of  the  Dynamotion  Outstanding  Securities  have  been  duly
authorized and are validly issued,  fully paid, and  nonassessable,  and no such
securities  were issued in  violation  of  preemptive  or similar  rights of any
shareholder or in violation of any  applicable  securities  laws.  Except as set
forth on Schedule  3.1.2.1,  there are no shares of capital  stock of Dynamotion
authorized,  issued, or outstanding, and, except for Options granted pursuant to
the Dynamotion Option Plans and as set forth on Schedule 3.1.2.1,

                              - 15 -

there  are no  preemptive  rights  or any  outstanding  subscriptions,  options,
warrants,  phantom stock,  stock  appreciation  or similar  rights,  convertible
securities, or any other rights, agreements, or commitments of Dynamotion of any
character  relating to the issued or unissued  capital stock or other securities
of Dynamotion. Except as set forth on Schedule 3.1.2.1, there are no outstanding
obligations  of  Dynamotion  to  repurchase,  redeem,  or otherwise  acquire any
Dynamotion Outstanding Securities.

holders (collectively,  "Holders") as of the date hereof,  indicating the number

Equivalents)  held by each Holder.  As used in this Agreement,  the term "to the
Knowledge of  Dynamotion"  means to the  knowledge,  after due  inquiry,  of the

                3.1.2.3 Redemption of Z Warrants. Schedule 3.1.2.3(a) states the
number of Z Warrants  outstanding.  Each Z Warrant is exercisable for .6941 of a
share of Dynamotion  Common Stock at an exercise price of $4.37 per share.  Upon
the  effectiveness  of the conversion  contemplated  by the Conversion  Proposal
(following the approval of the  Conversion  Proposal by holders of the requisite
percentages of Dynamotion Common Stock, Class A Stock, and Class B Stock), the Z
Warrants will be redeemable, without any further

                              - 16 -

<PAGE>


action  required  (other than payment of the  redemption  price) at a redemption

                     (k)  Any  change  not   described   above  in  the  assets,
liabilities, licenses, permits, or franchises of Dynamotion, or in any agreement
to  which  Dynamotion  is a  party  or  by  which  it  is  bound,  that,  either
individually  or in the  aggregate,  has had or is  reasonably  likely to have a
material  adverse  effect on the  business,  results  of  operations,  financial
condition,  properties, or assets of Dynamotion.  3.1.11 Prohibited Payments. To

its officers,  or directors in their  capacities as such, or any of Dynamotion's
properties or businesses. No pending litigation or proceeding listed on Schedule

promulgated by the U.S.  Department of Health and Human Services and the Federal
Communications Commission and foreign counterparts to such laws and regulations,
other than  violations  that  individually or in the aggregate do not, and, with
the passage of time will not,  have a material  adverse  effect on its business,
financial condition, results of operations, properties, or assets. Dynamotion is
not subject to any outstanding judgment,  order, writ, injunction, or decree and
has not been charged with, or, to the Knowledge of Dynamotion, threatened with a
charge of, a violation of any provision of any applicable law or regulation.

           3.1.14 Employment Matters.

                3.1.14.1 Labor  Matters.  Dynamotion is not a party or otherwise
subject to any collective  bargaining  agreement  governing the wages, hours, or

arbitration  proceeding  pending arising out of or under  collective  bargaining
agreements applicable to Dynamotion.  Dynamotion has not experienced any primary
work stoppage or other  organized  work stoppage  involving its employees in the
past two  years.  To the  Knowledge  of  Dynamotion,  there is no labor  strike,
slowdown,  or work stoppage occurring or threatened against any of its principal
suppliers  that is reasonably  likely to have a material  adverse  effect on the
business, financial condition,  results of operations,  properties, or assets of
Dynamotion.
                3.1.14.2 Employee Benefits. Schedule 3.1.14.2 lists all pension,
retirement, profit sharing, deferred compensation,  bonus, commission, incentive
compensation  (including cash,  stock, and option plans or  arrangements),  life
insurance,  health  and  disability  insurance,  hospitalization,  and all other
employee  benefit plans or  arrangements  (including,  without  limitation,  any
contracts or agreements with trustees, insurance companies or others relating to
any such employee  benefit plans or  arrangements)  established or maintained by
Dynamotion,  and Dynamotion  has provided ESI with complete and accurate  copies
of: (a) all such plans or  arrangements;  (b)  Dynamotion's  most recent  annual
report (Form 5500 series) filed with the Internal Revenue Service;  (c) the most
recent actuarial reports; and (d) all governmental rulings, determinations,  and
opinions (and pending requests for  governmental  rulings,  determinations,  and
opinions). The employee welfare benefit plans (within the meaning

                              - 25 -

<PAGE>

of Section  3(1) of the Employee  Retirement  Income  Security  Act of 1974,  as
amended ("ERISA")) and the employee pension benefit plans (within the meaning of
Section 3(2) of the ERISA)  established and maintained by Dynamotion (the "ERISA
Plans") are listed  separately  as ERISA Plans on Schedule  3.1.14.2.  The ERISA
Plans comply in all material respects with the applicable requirements of ERISA.
Dynamotion  has  received  from  the  Internal   Revenue   Service  a  favorable
determination  for each of the ERISA Plans and their related trusts that each of
the ERISA Plans that is an employee  pension  benefit  plan is  qualified  under
Section  401(a) of the Code and the related  trust is  tax-exempt  under Section
501(a) of the Code.  There has been no event  subsequent  to that  determination
that has adversely  affected the tax qualified  status of the ERISA Plans or the
exemption  of the  related  trusts  other than  changes in the Code that are not
effective as of the Closing Date. None of the ERISA Plans, its related trusts or
any  trustee,  investment  manager or  administrator  thereof  has  engaged in a
nonexempt  "prohibited  transaction,"  as such term is defined in Section 406 of
ERISA and Section  4975 of the Code.  There are not and have not been any excess
deferrals or excess  contributions  under any ERISA Plan. Each ERISA Plan is and
has been operated and  administered in conformity  with the  requirements of all
applicable  laws and  regulations,  whether or not the ERISA Plan documents have
been  amended  to reflect  such  requirements.  Except as set forth on  Schedule
3.1.14.2,  Dynamotion  has no obligation of any kind (whether under the terms of
the ERISA Plans or under any  understanding  with  employees)  to make  payments
under, or to pay contributions to, any plan,  agreement or other arrangement for
deferred  compensation  of employees,  whether or not tax qualified,  including,
without  limitation,  a single employer tax qualified plan, a tax qualified plan
of a controlled group of corporations, a multiemployer pension plan, a "defined

                              - 26 -

benefit"  plan,  a  nonqualified   deferred  compensation  plan,  an  individual
employment or compensation agreement or a commitment to provide medical benefits
to retirees.  Dynamotion  has never adopted,  maintained,  or contributed to any
plan or  arrangement  that is or was subject to Section 412 of the Code or Title
IV of ERISA (a "DB Plan"), nor has Dynamotion ever been a member of a controlled
group of  corporations,  group of trades or  businesses,  or affiliated  service
group (within the meaning of Sections 414(b), (c), and (m) of the Code) that has
adopted, maintained, or contributed to a DB Plan.

                3.1.14.3 Employment Agreements. There are no employment or other
agreements  or  understandings  of any kind  between  Dynamotion  and any of its
employees,   including  without  limitation  any  agreements  or  understandings
regarding  compensation  or commissions of any nature,  severance  payments,  or
retirement  benefits,  except  as  reflected  in the items  listed in  Schedules
3.1.14.2,   3.1.14.3,   and  3.1.14.4   and  except  for   standard   Dynamotion
confidentiality  and  assignment  agreements  as described in Section  3.1.14.5.
Schedule  3.1.14.3 lists all  Dynamotion's  employment or  supervisory  manuals,
employment or supervisory  policies,  and written information generally provided
to employees (such as applications or notices), and complete and accurate copies
of those manuals, policies, and written information have been provided to ESI.

                3.1.14.4 Compensation. Schedule 3.1.14.4 contains a complete and
accurate list of all current directors,  officers,  employees, or consultants of
Dynamotion, specifying their names and job designations, the total annual amount
paid or payable as cash and noncash  compensation  to each such person,  and the
basis  of such  compensation,  whether  fixed  or  commission  or a  combination
thereof, and the total amount of accrued benefits (including

                              - 27 -

<PAGE>

without limitation vacation,  sick, or wellness pay, if any) for such persons as
of December 31, 1995 and as of November 30,  1996.  Dynamotion  has not made any
commitment  entitling any employee to any payment in the event of termination or
resignation  that would  constitute a "parachute  payment" within the meaning of
Section  280G of the Code or that would in the  aggregate  exceed 100 percent of
such person's  annual base cash  compensation.  Dynamotion has no  discretionary
bonus  plans.  The  provisions  for wages and  salaries  accrued on the  Current
Balance  Sheet  are  adequate  for  salaries  and wages  accrued  as of the date
thereof,  including  accrued  vacation pay and sick or wellness pay, if any, and
Dynamotion  has accrued on its books and records all  obligations  for wages and
salaries and other compensation to its employees,  including but not limited to,
vacation  pay and sick or wellness  pay, if any, and all  commissions  and other
fees payable to agents, salesmen, and representatives.

                3.1.14.5   Confidentiality   and  Inventions   Agreements.   The
employees  and  consultants  of  Dynamotion  listed on  Schedule  3.1.14.5  have
previously signed a confidentiality and invention agreement substantially in the
form or forms attached hereto as Exhibit H.

           3.1.15 Title to and Condition of Real  Property.  Neither  Dynamotion
nor any Previous  Subsidiary  has ever owned any real  property,  and Dynamotion

or the  submission  of any  proposals or offers from any person  relating to any

furnish ESI with such financial and operating data and other  information in its
possession with respect to its business,  customers,  and properties as ESI from

document,  or  instrument  delivered  pursuant  to or in  connection  with  this
Agreement  will survive the  execution  and delivery of this  Agreement  and the
consummation of the transactions  contemplated  hereby, but will be extinguished
and be of no further force or effect 18 months after the Effective Time,  except
that any  claim  for which a Claim  Notice  (as  defined  in  Section  6.5.1) is
delivered  pursuant to Section  6.5.1  before the 18-month  survival  period has
elapsed will survive until the

                              - 71 -

<PAGE>


settlement  or other final  resolution  of such claim.  No Claim  Notice will be
effective if delivered after the time period specified in this Section 6.1.1.

           6.1.2  Survival of Article IV Covenants.  All of the covenants of any
party contained in Article IV of this Agreement will be  extinguished  and be of
no further force or effect after the Effective Time, except that Sections 4.1.4,
4.3.3,  4.3.4, 4.3.5, and 4.4 will survive the Effective Time in accordance with
their respective terms.

      6.2 Indemnification.  (a) From and after the Effective Time and subject to
the limitations of this Article VI, the Key Shareholders will, severally and not
jointly,  and only to the extent of the Escrowed  Property,  indemnify  and hold
harmless ESI and Merger Corp.  and their  respective  officers,  directors,  and
shareholders  (collectively,  the "Indemnified  Parties") from, for, and against
any losses,  costs,  expenses,  damages,  and liabilities,  including reasonable
attorneys' fees (collectively,  "Damages"),  incurred by an Indemnified Party by
reason of or arising out of any inaccuracy in any  representation or warranty or
the breach of any covenant of Dynamotion  made in this  Agreement  (after taking
into  account  any  revised  schedule  provided  pursuant  to  Section  5.3.15);
provided,  however, that for the purposes of this Section 6.2, the determination
of whether there has been a breach of any of  Dynamotion's  representations  and
warranties  contained in (i) Section  3.1.28 will be made without  regard to any
disclosures  contained in Schedule  3.1.28(a) (except as noted otherwise on such
schedule) and (ii) Section 3.1.25 will be made without regard to any disclosures
contained  in  Schedule  3.1.25.2.  (b) From and  after the  Effective  Time and
subject to the  limitations  of this  Article  VI,  each Key  Shareholder  will,
severally  and not jointly,  and only to the extent of his, her, or its Escrowed
Property, indemnify and hold harmless each Indemnified Party from, for,
                           
                                     - 72 -

<PAGE>


and  against  any Damages  incurred  by such  Indemnified  Party by reason of or
arising out of any inaccuracy in any representation or warranty or the breach of
any covenant of such Key Shareholder made in this Agreement.

      6.3 Escrow.  On the Closing  Date,  ESI will, on behalf of each of the Key
Shareholders,  deliver to the Escrow Agent an aggregate of  $1,500,000  worth of
the shares of ESI Common Stock to be received by the Key  Shareholders  pursuant
to Section 1.3 (such deposited shares, the "Escrowed  Property").  The shares to
be  delivered  to the  Escrow  Agent on behalf of each Key  Shareholder  will be
withheld  from the shares of ESI Common  Stock  otherwise to be received by such
Key  Shareholder  pursuant  to Section  1.3 in the amounts set forth on Schedule
6.3. The Escrowed  Property will be deposited  with the Escrow Agent pursuant to
the terms of the Escrow  Agreement.  The escrow  and the Escrow  Agreement  will
terminate and the Escrowed  Property will be distributed to the Key Shareholders
at the time and as provided for in the Escrow Agreement.

      6.4 Threshold for Indemnity Claims. No indemnification  payment obligation
will arise  under  this  Article  VI unless  and until the  aggregate  amount of
Damages  claimed  by all  Indemnified  Parties  under  this  Article  VI exceeds
$275,000  (the  "Claim  Threshold");  provided,  however,  that  once the  Claim
Threshold is exceeded,  all Damages of the  Indemnified  Parties,  including the
first $275,000 (in the aggregate) of Damages claimed by the Indemnified  Partes,
will be subject to the indemnity provisions of this Article VI.

      6.5 Claim Procedure for  Indemnification.  The obligations and liabilities
of the Key  Shareholders  in  connection  with  claims for  indemnification  for
Damages by an  Indemnified  Party will be  subject  to the  following  terms and
conditions:

                              - 73 -

<PAGE>


           6.5.1  Notice.  The  Indemnified  Party must give  written  notice (a
"Claim Notice") to the Key Shareholder  Representatives  and the Escrow Agent of
its  claim  for   indemnification  as  promptly  as  practicable   whenever  the
Indemnified Party has determined that there are facts or circumstances  that may
entitle  the  Indemnified  Party  to  indemnification  under  this  Article  VI;
provided,  however,  that the failure to give a timely  Claim Notice (so long as
such Claim Notice is within the time period specified in Section 6.1.1) will not
diminish the indemnification obligations hereunder except to the extent that the
delay in giving such Claim Notice  materially  adversely  affects the ability of
the Key  Shareholder  Representatives  to mitigate  Damages  with respect to any
claim.  The Claim Notice must set forth in  reasonable  detail the basis for the
claim, the nature of the Damages and the amount thereof, to the extent known.

           6.5.2 Response to Third Party Claim.  If the Claim Notice states that
a claim has been  asserted by a third party  against  the  Indemnified  Party (a
"Third Party Claim"), ESI will undertake,  conduct, and control, through counsel
of its choosing,  the good faith  settlement or defense of the Third Party Claim
and the Key  Shareholder  Representatives  will  provide such  assistance  as is
reasonably requested by ESI in connection with such settlement or defense.

           6.5.3  Diligent  Conduct.  If,  within five days after receipt by ESI
from the Key  Shareholder  Representatives  of  written  notice  that ESI is not
diligently  conducting  the defense or attempted  settlement  of any Third Party
Claim in good faith, ESI does not provide reasonably  sufficient evidence to the
Key Shareholder  Representatives that ESI is diligently  conducting such defense
or attempting such settlement in good faith, the Key Shareholder Representatives
will thereafter have the right to contest, settle or compromise such Third Party
Claim.

consent of Dynamotion and ESI.

      7.2  Termination Under Certain Other Conditions.

           7.2.1  Automatic  Termination.   This  Agreement  will  automatically
terminate  without  any  action by ESI,  Dynamotion,  Merger  Corp.,  or the Key
Shareholders if the Merger has not become  effective on or before June 15, 1997,
provided, however, that automatic termination of this Agreement pursuant to this
Section  7.2.1 will not limit the  liability  of any party whose  breach of this
Agreement  has been the cause of, or  resulted  in, the failure of the Merger to
occur on or before such date.

           7.2.2  Termination   by  ESI or  Dynamotion.  This  Agreement  may be
terminated  and the Merger may be  abandoned  at any time  before the  Effective
Time:

                (a) by ESI or Dynamotion if any Governmental Entity of competent
jurisdiction in the United States or any state has issued an order, judgment, or
decree  restraining,  enjoining,  or otherwise  prohibiting  the Merger and such
order, judgment, or decree has become final and nonappealable;

                (b) by ESI or Dynamotion if the requisite approval of the Merger
by the shareholders of Dynamotion has not been obtained by May 31, 1997;

                (c) by ESI if the Dynamotion Board of Directors has withdrawn or
modified in a manner  adverse to ESI its approval of the Merger,  this Agreement
or the transactions

                              - 75 -

<PAGE>


contemplated hereby or if Dynamotion or any officer, director,  employee, agent,
or  representative of Dynamotion takes any action that violates any provision of
Section 4.2.2; or

                (d)  by  Dynamotion  if  the   Dynamotion   Board  of  Directors
determines in good faith, upon advice of legal counsel, that termination of this
Agreement is required for the directors of Dynamotion to fulfill their fiduciary
duties and obligations under New York law.

      7.3 Effect of Termination and Abandonment.  In the event of termination of
this Agreement and  abandonment of the Merger pursuant to this Article VII, this
Agreement  immediately  will become void and of no effect,  except that Sections
4.1.4, 7.4, 8.1, 8.11, and 8.12 will survive the event of termination.

      7.4  Termination  Fee.   Dynamotion  agrees  to  pay  ESI  (provided  that
Dynamotion's  termination of this Agreement has not resulted from the failure of
any of the conditions to the obligations of Dynamotion and the Key  Shareholders
contained  in  Section  5.2)  by  wire  transfer,  the  sum of  $1,000,000  (the
"Termination Fee") in immediately  available funds if Dynamotion terminates this
Agreement  (other than  pursuant to Section  7.2.2(a)) and within one year after
termination of this  Agreement  agrees to an  Acquisition  Transaction  with any
person other than ESI or any of its affiliates and the  Acquisition  Transaction
results in a change in the beneficial owners of more than fifty percent (50%) of
the voting power of the capital stock of Dynamotion. Dynamotion will pay ESI the
Termination Fee promptly upon Dynamotion's execution of an agreement relating to
any such Acquisition Transaction.

      VOTING AGREEMENT

      This Voting Agreement ("Agreement") is entered into as of January 24, 1997
between Electro Scientific Industries,  Inc., an Oregon corporation ("ESI"), and
the shareholder of Dynamotion/ATI Corp., a New York corporation  ("Dynamotion"),
identified   on  the   signature   page  of  this   Agreement   as   Shareholder
("Shareholder").

      RECITALS

      A. ESI, Dynamotion, Dynamotion Merger Corp., a New York corporation wholly
owned by ESI ("Merger  Corp."),  and certain key  shareholders of Dynamotion are
parties to an  Agreement  of  Reorganization  and Merger dated as of January 24,
1997 (the "Merger Agreement").

      B.  The  Merger  Agreement  and  the  transactions   contemplated  thereby
(including the merger of Dynamotion  into Merger Corp.  (the  "Merger")) must be
approved by holders of the requisite  percentages of the  outstanding  shares of
capital  stock of  Dynamotion  entitled to vote upon the Merger  (such shares of
capital  stock,  the "Voting  Dynamotion  Securities")  at a special  meeting of
Dynamotion's  shareholders  (the  "Special  Meeting")  called for the purpose of
approving the Merger,  all in accordance  with the  requirements of the New York
Business  Corporation  Law,  Dynamotion's  Certificate  of  Incorporation,   and
Dynamotion's Bylaws.

      C. The Merger  Agreement  provides  that, in  connection  with the Merger,
Dynamotion will also submit for shareholder  approval at the Special Meeting,  a
proposal (the "Conversion  Proposal") to amend the terms of certain  outstanding
convertible  preferred  stock of  Dynamotion so that,  among other  things,  all
shares of such  convertible  preferred  stock will  automatically  convert  into
shares of Common Stock,  par value $0.04 per share,  of  Dynamotion  immediately
before the Merger takes effect.

      D. ESI has also required in the Merger Agreement that Shareholder  execute
and deliver to ESI and Merger Corp. this Agreement.

      AGREEMENT

NOW, THEREFORE, the parties agree as follows:

      1. Voting Agreement.  At the Special Meeting,  Shareholder will, in person
or by proxy, vote all of Shareholder's shares of Dynamotion Voting Securities in
favor of approving the Conversion Proposal and the Merger. Shareholder will also
vote all other Voting Dynamotion Securities over which such Shareholder may have
voting  rights,  whether as custodian for a minor,  by proxy,  or otherwise,  in
favor of approving the Conversion Proposal and the Merger.

       2.  Specific  Enforcement  of  Voting  Agreement.  Shareholder  expressly
acknowledges  that damages  alone will not be adequate  remedy for any breach by
Shareholder of this


<PAGE>



Agreement and that ESI, in addition to any other  remedies it may have,  will be
entitled  as a  matter  of  right,  to  injunctive  relief,  including  specific
performance,  in any court of competent  jurisdiction with respect to any actual
or threatened breach by Shareholder of the provisions of this Agreement.

       3.  Termination.  This  Agreement,  and all rights and obligations of the
parties  hereunder,  will terminate upon the first to occur of (a) the Effective
Time of the  Merger,  or (b)  the  date  upon  which  the  Merger  Agreement  is
terminated in accordance with its terms.

      4.    General Provisions.

            4.1  Amendment.  The  provisions of this Agreement may be amended or
waived  only by an  instrument  in  writing  signed by the party  against  which
enforcement of such amendment or waiver is sought.

            4.2  Governing  Law.  The  construction   and  performance  of  this
Agreement  will be  governed  by the laws of the state of Oregon,  exclusive  of
choice of law rules.

            4.3 Entire Agreement.  This Agreement  embodies the entire agreement
of the parties with respect to its subject  matter and  supersedes  all prior or
contemporaneous   understandings  and  agreements,   whether  oral  or  written,
regarding its subject matter.

            4.4  Counterparts.  This Agreement may be executed in  counterparts,
each of which will be deemed to be an original but both of which  together  will
constitute one and the same Agreement.

            4.5 Agreement  Contingent.  The parties hereto  expressly agree that
this Agreement and all of its terms and provisions will be of no force or effect
until the execution and delivery of the Merger  Agreement by each of the parties
thereto.
