         ITEM 5.   OTHER EVENTS

         As of January 24, 1997, Dynamotion/ATI Corp., a New York corporation
("Dynamotion"), Electro Scientific Industries, Inc., an Oregon corporation
("ESI"), Dynamotion Merger Corp., a New York corporation ("Merger Corp."), and
certain key shareholders of Dynamotion entered into an Agreement of
Reorganization and Merger (the "Merger Agreement") pursuant to which, among
other things, Dynamotion will be merged with and into Merger Corp., a
wholly-owned subsidiary of ESI formed for this purpose, with Merger Corp.
continuing as the surviving corporation (the "Merger").

         The Merger Agreement provides that, as a precondition to the Merger,
the shareholders of Dynamotion must approve the Merger and proposals to amend
Dynamotion's current Certificate of Incorporation (the "Certificate") to
provide that if the Merger occurs, immediately before the consummation of the
Merger each share of the outstanding Class A Non-Cumulative Redeemable
Convertible Preferred Shares of Dynamotion, par value $0.01 per share ("Class A
Stock"), and Class B Cumulative Convertible Preferred Shares of Dynamotion, par
value $0.01 per share ("Class B Stock"), will automatically convert into Common
Shares of Dynamotion, par value $0.04 per share ("Dynamotion Common Stock"),
and the right to receive certain cash payments and cash dividends,
respectively, as specified in the Merger Agreement (the "Conversion
Proposals").  Immediately before the Merger, Dynamotion's outstanding Class A
Redeemable Common Stock Purchase Warrants ("Z Warrants") will be redeemed in
accordance with their terms.  The proposal to approve the Merger (the "Merger
Proposal") and the Conversion Proposals will all be submitted to Dynamotion's
shareholders at the special meeting of Dynamotion's shareholders (the "Special
Meeting") to be held to consider and vote on the Merger Proposal and the 
Conversion Proposals.

         In the proposed Merger, the holders of outstanding shares of
Dynamotion Common Stock (including the Common Stock issuable upon conversion of
the Class A Stock and the Class B Stock pursuant to the Conversion Proposals)
will be converted into and represent the right to receive shares of common
stock, no par value, of ESI (the "ESI Common Stock") valued at $13,000,000, in
accordance with the terms of the Merger Agreement.  Cash in lieu of certain
fractional shares will be paid to each former Dynamotion shareholder who would
otherwise be entitled to receive a fractional share of ESI Common Stock after
giving effect to the conversion of all of such shareholder's shares of
Dynamotion Common Stock into ESI Common Stock pursuant to the Merger.  Assuming
the conversion of all outstanding shares of Class A Stock and Class B Stock
into Dynamotion Common Stock pursuant to the Conversion Proposals, and assuming
the issuance of 330,302 shares of Dynamotion Common Stock issuable upon
exercise of an outstanding warrant, approximately 6,387,770 shares of
Dynamotion Common Stock will be issued and outstanding at the time of the
Merger.  The actual number of shares of Dynamotion Common Stock outstanding on
the day of the Merger may increase if any outstanding employee stock options or
any outstanding warrants (other than the warrant referred to in the immediately
preceding sentence) are exercised.

         Consummation of the proposed Merger is subject to the satisfaction of
a number of conditions, including but not limited to the approval of the Merger
Proposal and the Conversion Proposals by Dynamotion's shareholders at the
Special Meeting.  Two shareholders of Dynamotion who together may be deemed to
be the beneficial owners of approximately 588,658 shares of Dynamotion Common
Stock (including 330,302 shares of Dynamotion Common Stock issuable upon
exercise of an


                                      -2-

outstanding warrant) and approximately 2,000,000 shares of Class B Stock have
each separately agreed with ESI to vote such securities in favor of the Merger
Proposal and Conversion Proposals in accordance with the terms of that certain
Voting Agreement dated as of January 24, 1997 (the "Voting Agreement").

         The foregoing descriptions of the Merger Agreement and the Voting
Agreement are qualified in their entirety by reference to the terms of the
Merger Agreement and Voting Agreement, copies of which are attached as Exhibit
99.1 and Exhibit 99.2 hereto, respectively, and incorporated by reference.

         On January 17, 1997, Dynamotion was notified that the Dynamotion
Common Stock, the Class A Stock and the Z Warrants had been delisted from the
NASDAQ Small Capitalization Market System.

         Dynamotion expects to report a loss for the fourth quarter ended
December 31, 1996 and for the 1996 fiscal year.  On January 3, 1997, Dynamotion
accepted a $500,000 cash payment as payment in full for a $800,000 promissory
note issued in connection with Dynamotion's third quarter 1996 sale of the
assets related to the ATI router product line.

                                   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>   16

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>   17

                 (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>   18

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>   20

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>   21

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.













                                       8
<PAGE>   22

                 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>   23

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.

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,

                         REPRESENTATIONS AND WARRANTIES

         3.1     Representations and Warranties of Dynamotion.  Dynamotion
hereby represents and warrants to ESI and Merger Corp as follows:

                 3.1.1    Organization and Status.  Dynamotion is a corporation
duly organized, validly existing, and in good standing under the laws of its
jurisdiction of incorporation and is duly qualified and in good standing as a
foreign corporation in each jurisdiction where its properties (whether owned,
leased, or operated) or its business conducted require such qualification,
except where the failure to so qualify or be in good standing, when taken
together with all such failures, would not have a material adverse effect on
Dynamotion.  Dynamotion has all requisite corporate power and authority to own,
operate, and lease its property and to carry on its businesses as they are now
being conducted.  Dynamotion has delivered to ESI complete and accurate copies
of the Certificate of Incorporation ("Certificate of Incorporation") and the
Bylaws of Dynamotion ("Bylaws"), each as amended to the date hereof.

                 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
<PAGE>   29

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.



                          3.1.2.2  Dynamotion Outstanding Securities Holders.
Schedule 3.1.2.2 sets forth a complete and accurate list of each shareholder
who, to the Knowledge of Dynamotion, owns (beneficially or of record) five
percent or more of the voting power of any class of Dynamotion capital stock,
as well as all warrant holders (other than holders of publicly-traded Z
Warrants) and Option holders (collectively, "Holders") as of the date hereof,
indicating the number of Dynamotion Outstanding Securities (and their
respective Common Stock 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 individuals listed on Schedule 3.1-K

                          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>   30

action required (other than payment of the redemption price) at a redemption
price of $0.05 per Z Warrant, provided that the actions listed in Schedule
3.1.2.3(b) have been taken.

                          3.1.2.4  Convertible Debt.  The convertible debt of
Dynamotion outstanding pursuant to notes issued to the parties listed on
Schedule 3.1.2.4  (the "Convertible Debt") is convertible into shares of
Dynamotion Common Stock only upon Dynamotion's default with respect to the
Convertible Debt.  Dynamotion is not in default with respect to the Convertible
Debt except where the holder of the Convertible Debt has signed a written
agreement not to convert until at least 10 business days after the Effective
Time or until this Agreement has been terminated, whichever occurs first.

                 3.1.3    Corporate Authority.  Dynamotion has the corporate
power and authority and has taken all corporate action necessary to execute and
deliver this Agreement and to consummate the transactions contemplated hereby.
This Agreement has been duly and validly authorized by the Dynamotion Board of
Directors and validly executed and delivered by Dynamotion.  This Agreement
constitutes the valid and binding obligation of  Dynamotion, enforceable in
accordance with its terms, except as enforcement may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting
the enforcement of creditors' rights generally and except that the availability
of the equitable remedy of specific performance or injunctive relief is subject
to the discretion of the court before which any proceeding may be brought.

                 3.1.4    Section 368(a)(2)(D) Asset Requirement.  Merger Corp.
will acquire at least 90 percent of the fair market value of the net assets and
at least 70 percent of the fair market value of the gross assets held by
Dynamotion immediately before the Merger.  For



















                                       17
<PAGE>   31

purposes of this representation, amounts, if any, paid by Dynamotion to
Dissenting Shareholders, amounts paid by Dynamotion to shareholders who receive
cash or other property, Dynamotion assets used to pay its reorganization
expenses, and all redemptions and distributions (except for regular, normal
dividends) made by Dynamotion immediately preceding the Effective Time will be
included as assets of Dynamotion held immediately before the Merger.

                 3.1.5    Governmental Filings.  Other than the filing of (a)
the Certificate of Merger contemplated by Article I, (b) the Proxy
Statement/Prospectus described in Section 4.2.4, and (c) a Certificate of
Amendment to Dynamotion's Certificate of Incorporation relating to the
Conversion Proposal, no notices, reports or other filings are required to be
made by Dynamotion with, nor, except as set forth on Schedule 3.1.5 are any
consents, registrations, approvals, permits, or authorizations required to be
obtained by Dynamotion from, any domestic or foreign governmental or regulatory
authority, agency, court, commission or other entity ("Governmental Entity") in
connection with the execution and delivery of this Agreement by Dynamotion and
the consummation by Dynamotion of the transactions contemplated hereby.

                 3.1.6    Investments; Subsidiaries.  All direct or indirect
investments of Dynamotion in any corporation, partnership, association, joint
venture or other entity are listed in Schedule 3.1.6(a).  Dynamotion has no
subsidiaries.  All previously existing subsidiaries of Dynamotion or any
predecessor (each, a "Previous Subsidiary and together, the "Previous
Subsidiaries") are listed on Schedule 3.1.6(b).

                 3.1.7    No Adverse Consequences.  Neither the execution and
delivery of this Agreement by Dynamotion nor the consummation of the
transactions contemplated by this Agreement will (a) result in the creation or
imposition of any lien, charge, encumbrance or

















                                       18
<PAGE>   32

restriction on any of the assets or properties of Dynamotion, (b) violate any
provision of the Certificate of Incorporation or Bylaws of Dynamotion, (c)
violate any statute, judgment, order, injunction, decree, rule, regulation or
ruling of any Governmental Entity applicable to Dynamotion, or (d) except as
set forth on Schedule 3.1.7, either alone or with the giving of notice or the
passage of time or both, conflict with, constitute grounds for termination of,
accelerate the performance required by, accelerate the maturity of any
indebtedness or obligation under, result in the breach of the terms, conditions
or provisions of, or constitute a default under any mortgage, deed of trust,
indenture, note, bond, lease, license, permit, or other agreement, instrument,
or obligation to which Dynamotion is a party or by which it is bound.

                 3.1.8    Financial Statements.  Dynamotion has furnished to
ESI an audited balance sheet of Dynamotion as of December 31, 1995, and the
related statements of operations, shareholders' equity, and cash flows or the
period then ended, and the unaudited balance sheet of Dynamotion as of
September 30, 1996 (the "Current Balance Sheet") and the related statements of
operations, shareholders' equity, and cash flows for the nine months then
ended, and the Updated Financial Statements delivered at or before the Closing
pursuant to Section 5.3.7 (all such balance sheets and statements collectively,
the "Financial Statements").  The Financial Statements are (or will be, in the
case of the Updated Financial Statements) complete and accurate in all material
respects and present fairly the financial position and operating results of
Dynamotion as of the dates and for the periods indicated therein, and have been
(or will be, in the case of the Updated Financial Statements) prepared in
accordance with generally accepted accounting principles and applicable
accounting rules and regulations of the Securities and Exchange Commission (the
"SEC").  The Financial Statements (including notes















                                       19
<PAGE>   33

and schedules) are (or will be, in the case of the Updated Financial
Statements) in accordance with the books and records of the Company.

                 3.1.9    Undisclosed Liabilities.  Except for current
liabilities incurred after September 30, 1996 in the ordinary course of
business and of a type and in an amount consistent with past practices and not
more in the aggregate than $150,000, Dynamotion has no liability or obligation
(whether absolute, accrued, contingent or otherwise, and whether due or to
become due) that is not accrued, reserved against, or identified on the Current
Balance Sheet.  Except as set forth on Schedule 3.1.9, there are no rights of
return or other agreements between Dynamotion and any customer that would cause
any sales reflected in the Financial Statements to fail to qualify as sales in
accordance with generally accepted accounting principles, applicable accounting
rules and regulations of the SEC, and Dynamotion's revenue recognition policy
as reflected in the Financial Statements.  Notwithstanding the foregoing, as to
any subject matter covered by a specific representation and warranty of
Dynamotion elsewhere in this Agreement, no fact or occurrence that would not
breach Dynamotion's specific representation and warranty covering that subject
matter will be deemed to be a breach of the representation and warranty
contained in this Section 3.1.9.

                 3.1.10   Absence of Certain Changes or Events.

                          3.1.10.1  Absence of Changes  or Events Since

Dynamotion; any special bonus or remuneration paid; any written employment
contract executed or amended; or any change in personnel policies;

                                       22
<PAGE>   36

                                  (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 the Knowledge of Dynamotion,
neither Dynamotion nor any shareholder, officer, director, or other person or
entity has, directly or indirectly, on behalf of or with respect to the
business or operations of Dynamotion or any Previous Subsidiary, (a) made any
payment outside the ordinary course of business to any purchasing or selling
agent or other person charged with similar duties of any entity to which
Dynamotion sells or from which Dynamotion buys products, for the purpose of
influencing such agent or person to buy products from or sell products to
Dynamotion which payment was not legal to make or receive under any applicable
law or regulation of the United States or any other country or territory; or
(b) engaged in any transaction, maintained any bank account, or used any

properties or businesses.  No pending litigation or proceeding listed on
Schedule 3.1.12 seeks injunctive relief against Dynamotion.  For the purposes
of this Section 3.1.12, the term "Litigation Reserves" means the amounts
specified on Schedule 3.1.12















                                       23
<PAGE>   37

as such.  The pending litigation and proceedings listed on Schedule 3.1.12 will
not, if settled, decided, or otherwise resolved in favor of the opposing party
or parties, result in any payment obligations of Dynamotion (including without
limitation damages and attorneys' fees) greater, in the aggregate, than the
Litigation Reserves.

                 3.1.13   Compliance with Laws; Judgments.  Dynamotion and each
Previous Subsidiary has at all relevant times conducted its business in
compliance with (a) the provisions of its Certificate or Articles of
Incorporation, Bylaws, and (b) all applicable laws, regulations, and standards,
including without limitation the United States Export Control Act and all
applicable regulations 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.

                          3.1.14.1         Labor Matters.  Dynamotion is not a
party or otherwise subject to any collective bargaining agreement governing the
wages, hours, or terms of employment of its employees.  Dynamotion is, and
Dynamotion and each Previous Subsidiary has been, in compliance with all
applicable laws regarding employment and employment practices, terms and
conditions of employment, wages, and hours and is not and has not been engaged
in any unfair labor practice.  There is no (a) unfair labor practice complaint

Dynamotion pending before the National Labor Relations Board or any other
Governmental Entity; (b) labor strike, slowdown or work stoppage actually
occurring or, to the Knowledge of Dynamotion, threatened against Dynamotion;
(c) representation petition respecting the employees of Dynamotion pending
before the National Labor Relations Board or similar agency; or (d) grievance
or any 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

<PAGE>   39

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

contains a complete and accurate list of all current directors, officers,
employees, or consultants of Dynamotion, specifying their names and job

of December 31, 1995 and as of November 30, 1996.  Dynamotion has not made any

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

consenting corporation pursuant to Section 341(f) of the Code.

New York law and (ii) before furnishing such information to or entering into
discussions or negotiations with such third party, Dynamotion provides prompt
written notice to ESI of such proposal or offer and, to the extent not
inconsistent with the fiduciary duties of Dynamotion's officers and directors,
provides

properties as ESI from time to time reasonably requests.  Without limitation of
the foregoing, Dynamotion will permit ESI to conduct an operations review at
the plant level during which ESI will have access to the plant managers, sales
and marketing managers, finance officers, and technology, environmental, and
human resource managers of each Dynamotion operating facility, and will make
all reasonable efforts to arrange for ESI (or its representatives or agents) to
visit such Dynamotion customers as ESI may reasonably request.  Any such
investigations (a) will be conducted in such a manner as not to interfere
unreasonably with the operation of Dynamotion's business or the businesses of
Dynamotion's customers; and (b) will not diminish any of the representations
and warranties contained in this Agreement.

                                   ARTICLE VI

                          SURVIVAL AND INDEMNIFICATION

         6.1     Survival.

                 6.1.1    Survival of Representations and Warranties.  All
representations and warranties of any party contained in this Agreement or in
any agreement, 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>   85

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>   86

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>   87

                 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.

                                  ARTICLE VII

                                  TERMINATION

         7.1     Termination by Mutual Consent.  This Agreement may be
terminated and the Merger may be abandoned at any time before the Effective
Time by the mutual 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>   89

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.

                           MISCELLANEOUS AND GENERAL

         8.1     Payment of Expenses.  Each party will be responsible for the
costs and expenses incurred by it in connection with this Agreement, the
Merger, and the other transactions contemplated by this Agreement, provided
that nothing in this Agreement will limit the right, if any, of a non-breaching
party to obtain damages, including attorneys' fees, incurred as a result of a
breach of this Agreement by another party.

         8.2     Entire Agreement.  This Agreement, including the schedules and

agreement between the parties hereto and supersede all prior agreements and
understandings, oral and written, among the parties hereto with respect to its
subject matter.

parties hereto without the prior written consent of each of ESI and Dynamotion.

inure to the benefit of and be binding upon the parties hereto and their
respective successors and assigns, subject to the restrictions on assignment
contained in Section 8.3.  Nothing express or implied in this Agreement is
intended or will be construed to confer upon or give to a person, firm, or
corporation other than the parties hereto any rights or remedies under or by
reason of this Agreement or any transaction contemplated hereby, except for the
provisions of Sections 4.3.5 and 4.4 concerning indemnification of current and
former officers and directors of Dynamotion under the Merger Corp. Certificate.

         8.5     Amendment and Modification.  Subject to applicable law, this
Agreement may be amended, modified, and supplemented at any time before or at
the Closing, whether before or after the vote of the shareholders of
Dynamotion, by written agreement executed and delivered by each of the Key
Shareholders and by the duly authorized officers of Dynamotion, ESI, and Merger
Corp.

         8.6     Waiver of Conditions.  The conditions to each of the parties'
obligations to consummate the Merger are for the sole benefit of such party and
may be waived by such party in whole or in part to the extent permitted by
applicable law; provided, however, that any waiver by a party must be in
writing.

         8.7     Counterparts.  For the convenience of the parties hereto, this
Agreement may be executed in any number of counterparts, each such counterpart
being deemed to be an original instrument, and all such counterparts will
together constitute the same agreement.

         8.8     Captions.  The article, section and paragraph captions used in
this Agreement are for convenience of reference only, do not constitute a part
of this Agreement and will not be deemed to limit or otherwise affect any of
the provisions hereof.

         8.9     Subsidiary.  When a reference is made in this Agreement to a
subsidiary of a party, the term "subsidiary" means any corporation or other
organization, whether incorporated or unincorporated, of which at least a
majority of the securities or interests having by the terms thereof ordinary
voting power to elect a majority of the board of directors or others performing
similar functions with respect to such corporation or other organization is
directly or indirectly owned or controlled by such party or by any one or more
of its subsidiaries, or by such party and one or more of its subsidiaries.

                                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>   2

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.
