                            REORGANIZATION AND MERGER


     THIS AGREEMENT OF REORGANIZATION AND MERGER (this "Agreement") is entered
into as of June 26, 1997 among Electro Scientific Industries, Inc., an Oregon
corporation ("ESI"), Chip Star Inc., a California corporation ("Chip Star"), CI

                                    RECITALS

     A. The Boards of Directors of ESI and Chip Star have determined that it is
in the best interests of their respective shareholders for ESI to acquire Chip
Star upon the terms and subject to the conditions set forth herein.

     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").

                                    AGREEMENT

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

<PAGE>
                                    ARTICLE I
                                   THE MERGER

     1.1 The Merger. Pursuant to the laws of the States of California and
Oregon, and subject to and in accordance with the terms and conditions of this
Agreement and the Plan of Merger attached hereto as Exhibit A, Merger Corp.
shall be merged with and into Chip Star, and the outstanding shares of Chip Star
Common Stock, no par value (the "Chip Star Common Stock") shall be converted
into shares of ESI Common Stock, without par value (the "ESI Common Stock"), in
a transaction intended to qualify as a tax-free reorganization under Section
368(a)(1)(A) and (a)(2)(E) of the Code. Chip Star and Merger Corp. shall execute
a Certificate of Merger and Articles of Merger, to be filed with the Secretary
of State of California and the Secretary of State of Oregon, respectively, on
the Closing Date, as defined in Section 1.5, or as soon thereafter as
practicable. The merger of Merger Corp. with and into Chip Star (the "Merger")
shall take effect (the "Effective Time") upon the later of the time when the
Certificate of Merger is duly filed with the Secretary of State of the State of
California, and the time when the Articles of Merger are duly filed with the
Corporation Division of the Secretary of State of the State of Oregon, or at
such other time as the parties may agree upon in writing pursuant to applicable
law.

     1.2 Effect of Merger.

          1.2.1 The Surviving Corporation. At the Effective Time, Merger Corp.
shall be merged with and into Chip Star in the manner and with the effect
provided by the California Corporations Code (the "CCC") and the Oregon Business
Corporation Act (the "OBCA"), the separate corporate existence of Merger Corp.
shall cease and Chip Star shall be the surviving

                                       2
<PAGE>
corporation (the "Surviving Corporation"). The outstanding shares of Chip Star
Common Stock shall be converted into shares of ESI Common Stock, and the
outstanding shares of capital stock of Merger Corp. shall be converted into
shares of capital stock of the Surviving Corporation, all on the basis, terms
and conditions described in Section 1.3.

          1.2.2 Directors and Officers. At and as of the Effective Time, the
directors and officers of the Surviving Corporation shall be as follows:

          Directors

          Donald R. VanLuvanee
          Barry L. Harmon
          Larry T. Rapp

          Officers

          Donald R. VanLuvanee      President and Chief Executive Officer
          Barry L. Harmon           Chief Financial Officer
          Larry T. Rapp             Secretary

     1.3 Merger Consideration. Each share of Chip Star Common Stock outstanding
immediately before the Effective Time will be converted into the right to
receive a fraction of a share of ESI Common Stock (such ESI Common Stock, 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 700,000 shares of ESI
Common Stock; and

          (b) the "Conversion Ratio Denominator" will be equal to the number of
shares of Chip Star Common Stock outstanding immediately before the Effective
Time plus the number

                                       3
<PAGE>
of shares of Chip Star Common Stock that are issuable as of the Closing Date
upon the exercise of options and rights then outstanding under the Chip Star
Inc. Incentive Stock Option Plan dated April 23, 1993.

          1.3.1 Chip Star Stock. Each share of Chip Star Common Stock that is
outstanding immediately before the Effective Time 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 prior to the Effective Time shall, by virtue
of the Merger and without any action on the part of the holder thereof, cease to
exist and be converted into and become one share of common stock of the
Surviving Corporation. After the Effective Time, ESI, the sole holder of shares
of Merger Corp. common stock outstanding immediately prior to the Effective
Time, shall, upon surrender for cancellation of a certificate representing such
shares to the Surviving Corporation, be entitled to receive in exchange
therefore a certificate representing the number of shares of common stock of the
Surviving Corporation into which such shares of Merger Corp. common stock have
been converted pursuant to this Section 1.3.2. Until so surrendered, the
certificates which prior to the Merger represented shares of Merger Corp. common
stock shall be deemed, for all corporate purposes, including voting entitlement,
to evidence ownership of the shares of the Surviving Corporation common stock
into which such shares of Merger Corp. common stock shall have been converted.

          1.3.3 Options. Except as otherwise provided in this Section 1.3.3, the
terms and provisions of any stock options held by Chip Star option holders, all
of which are identified

                                       4
<PAGE>
in Schedule 3.1.2 (the "Options"), shall 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 shall
be assumed by ESI and shall be converted into an option to purchase the whole
number of shares of ESI Common Stock which the holder of the Option would have
been entitled to receive had such holder exercised the Option in full
immediately prior to the Effective Time (whether or not such Option shall then
have been exercisable) (rounded to the nearest whole number). The exercise price
per share shall be adjusted by dividing the stated exercise price 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 the Options will to the extent permitted by law
and otherwise reasonably practicable be unchanged; each Option which is an
Incentive Stock Option shall be adjusted in accordance with the requirements of
Section 424(a) of the Code so as not to constitute a modification, renewal or
extension of the Option within the meaning of Section 424(h) of the Code.
Continuous employment with Chip Star shall be credited to the optionee for
purposes of determining the vesting of the number of shares of ESI Common Stock
subject to exercise under the 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 Chip Star Common Stock outstanding immediately prior to the
Effective Time, upon surrender to ESI or its agent designated for such purpose
of a certificate or certificates representing such shares shall be entitled to
receive (x) a certificate representing the number of shares of ESI Common Stock
into which such shares of Chip Star Common Stock shall have

                                       5
<PAGE>
been converted pursuant to the provisions of Section 1.3 less the number of such
shares determined to be Escrowed Property (as defined in Section 6.3) and (y)
subject to Section 6.3 and the provisions of the Escrow Agreement, 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 for Chip Star Common Stock surrendered
in exchange therefor is registered, it shall be a condition of the issuance
thereof that the certificate so surrendered shall 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 satisfaction of ESI or its agent that
such tax has been paid or is not payable. If any holder of Chip Star Common
Stock canceled and retired in accordance with this Agreement is unable to
deliver a certificate or certificates representing such shares of the holder,
ESI, in the absence of actual notice that any shares theretofore represented by
any such certificate have been acquired by a bona fide purchaser, shall deliver
to such holder the number of shares of Common Stock to which such holder is
entitled in accordance with the provisions of this Agreement upon the
presentation of the following: (i) evidence satisfactory to ESI (a) that such
person is the owner of the shares theretofore represented by each certificate
claimed by him to be lost, wrongfully taken or destroyed and (b) that he is the
person who would be entitled to present each such certificate for conversion
pursuant to this Agreement; and (ii) such security or indemnity as may be

          issued without registration under the Securities Act of 1933
          (the 'Act') or any state securities laws. They may not be
          sold, assigned, pledged or otherwise transferred for value

          state securities laws or the Corporation receives an opinion
          of counsel satisfactory to it, or otherwise satisfies
          itself, that registration is not required."

          "The securities represented by this certificate were issued
          pursuant to a business combination which is being accounted
          for as a pooling of interests and may not be sold, nor may
          the owner thereof reduce his risk relative thereto in any

foreign governmental or regulatory authority, agency, court, commission or other

this Agreement by Chip Star and the Shareholders and the consummation by Chip
Star and the Shareholders of the transactions contemplated hereby.

          3.1.5 Investments; Subsidiaries. No direct or indirect investments in
any corporation, partnership, association, joint venture or other entity by Chip

this Agreement by Chip Star or the Shareholders nor the consummation of the
transactions contemplated by this Agreement will (a) result in the creation or
imposition of any lien, charge, encumbrance or restriction on any of the assets
or properties of Chip Star, (b) violate any provision of the Articles of
Incorporation or Bylaws of Chip Star, (c) violate any statute,

Star's principal suppliers that might be expected to have a material adverse
effect on the business, financial condition, results of operations, properties,
or assets of Chip Star. All of the employees of Chip Star are citizens or
permanent

                                       17
<PAGE>
residents of the United States. No employee of Chip Star is the beneficiary
under an employer-sponsored non-immigrant visa and no approvals, permits or
consents of any governmental entity are required in order for Chip Star to
employ any current employee as a result of or in connection with such employee's
immigration status in the United States. Chip Star has fully completed and
retained a Form I-9 for each of its employees in accordance with applicable law,

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
Chip Star, and complete and accurate copies of all those plans or arrangements
have been provided to ESI. The employee pension benefit plans (within the
meaning of Section 3(2) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA")) established and maintained by Chip Star that are subject
to ERISA (the "ERISA Plans") are listed separately as ERISA Plans on Schedule
3.1.13.2. The ERISA Plans comply in all material respects with the applicable
requirements of ERISA. Chip Star 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 is qualified under Section 401(a) of the Code and
the related trust is tax-exempt

                                       18
<PAGE>
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. Chip Star 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 benefit" plan, a nonqualified deferred
compensation plan, an individual employment or compensation agreement or a
commitment to provide medical benefits to retirees.

               3.1.13.3 Employment Agreements. Each employee of Chip Star is an
"at-will" employee and there are no written employment, commission or
compensation agreements of any kind between Chip Star and any of its employees.
Schedule 3.1.13.3 lists all Chip Star'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

                                       19
<PAGE>

its employees, including without limitation any agreements or understandings
regarding compensation of any nature, severance payments or retirement benefits,
except as reflected in the items listed in Schedules 3.1.13.2 and 3.1.13.4.

accurate list of all current directors, officers, employees or consultants of
Chip Star, specifying their names and job designations, the total 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 without limitation vacation, sick or
wellness pay) for such persons as of April 30, 1997. Except as set forth in
Schedules 3.1.13.2, 3.1.13.3 or the agreements described in Section 3.1.13.5,
Chip Star is not a party to any employment contract or agreement and has not
made any other 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 would in the aggregate exceed 100
percent of such person's annual base cash compensation. The provisions for wages
and salaries accrued on the Current Balance Sheet are adequate for salaries and
wages, including accrued vacation pay and sick or wellness pay, and Chip Star
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, and all commissions and other fees payable to agents,
salesmen, and representatives.

consultant that has been given access to Chip Star's Intellectual Property (as
defined in Section 3.1.16)

Property has previously signed a confidentiality and invention agreement in the

Property, nor any improvements on the Leased Real Property, violates any
applicable building or zoning code or regulation of any governmental authority
having jurisdiction, except where such violation would not have a material
adverse affect on Chip Star. The Leased Real Property includes all real property
necessary to conduct the business of Chip Star as currently conducted. None of
the Leased Real Property has been condemned or otherwise taken by public
authority and no such condemnation is, to the knowledge of Chip Star and the
Shareholders, threatened or contemplated.

          3.1.15 Title to and Condition of Fixed Assets. Schedule 3.1.15
contains a complete and accurate list of all tangible personal property
(excluding inventory) owned or leased by Chip Star (the "Tangible Personal

                                   ARTICLE VI

                          SURVIVAL AND INDEMNIFICATION

     6.1 Survival. All representations and warranties of any party contained in
this Agreement shall survive the execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby, but shall be
extinguished and be of no further force or effect one year after the Closing
Date. No Claim Notice shall be effective if delivered after the time period
referred to above in this Section 6.1.

     6.2 Scope of Indemnification. From and after the Effective Time and subject
to the limitations of this Article VI, each Shareholder will severally indemnify
and hold harmless ESI and Merger Corp. and their respective officers, directors
and shareholders (collectively, the "Indemnified Parties") from, for and against
any such 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 Chip Star or the Shareholders made in this
Agreement; provided, however, that the limitation of liability for each
Shareholder shall be the shares of ESI Common Stock placed in escrow by such
Shareholder pursuant to Section 6.3.

     6.3 Escrow. On the Closing Date, ESI shall, on behalf of each of the
Shareholders, deliver to the Escrow Agent 10 percent of such Shareholder's
shares of the ESI Common Stock to be received by such Shareholder pursuant to
Section 1.3, provided that the shares to be delivered on behalf of each
Shareholder shall be rounded downward to the nearest whole share of ESI Common
Stock (such deposited shares shall be referred to as the "Escrowed Property").
The Escrowed Property will be deposited with the Escrow Agent pursuant to the
terms of the

                                       51
<PAGE>
Escrow Agreement. The escrow and the Escrow Agreement shall terminate and the
Escrowed Property shall be distributed to the Shareholders at the earliest time
provided for in the Escrow Agreement, but not later than the first anniversary
of the Closing Date.

     6.4 Limitations. The liability of the Shareholders pursuant to Section 6.2
shall be subject to the following limitations:

          6.4.1 Minor Claims. The Shareholders shall not have any liability or
indemnity obligation under Section 6.2 with respect to the first $25,000 of
Damages of the Indemnified Parties (the "Basket"). The Basket is subject to
adjustment as set forth in Section 6.6.

          6.4.2 Escrowed Property. The indemnity obligation of the Shareholders
under Section 6.2 shall be satisfied solely out of the Escrowed Property in
accordance with the Escrow Agreement. To make a claim against the Escrowed
Property, the Indemnified Parties must deliver a Claim Notice within 12 months
of the Closing Date.

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

          6.5.1 Notice. The Indemnified Party shall give written notice to the
Shareholders and, for claims made during the term of the Escrow Agreement, the
Escrow Agent of its claim for indemnification as promptly as practicable
whenever the Indemnified Party shall have determined that there are facts or
circumstances which entitle ESI to indemnification under this Article VI;
provided, however, that the failure to give a timely notice of a claim for
indemnification shall not diminish the indemnification obligations hereunder
except to the extent that the delay in giving such notice materially adversely
affects the ability of the Shareholders

                                       52
<PAGE>
to mitigate Damages with respect to any claim. The notice ("Claim Notice") shall
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 shall undertake, conduct and control, through counsel of its
choosing, the good faith settlement or defense of the Third Party Claim. The
Shareholders shall be kept apprised of the status of such Third Party Claims.

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

     6.6 Adjustment of the Basket.

          6.6.1 Physical Count of Assets. On or before July 31, 1997, ESI will
conduct a physical count of Chip Star inventory. If and to the extent the
aggregate value of the inventory determined by such count (the "Physical Count
Value") exceeds the book value for inventory reflected on Chip Star books and
records as of the date of the count, that amount will be added to the Basket; if
and to the extent the Physical Count Value is less than the book value for
inventory reflected on Chip Star books and records as of the date of the count,
the Basket will be reduced by that amount. If the Physical Count Value is less
than the book value of the

                                       53
<PAGE>
inventory, and the difference is greater than the size of the Basket, then the
Basket will be reduced to zero, and any difference in book value and the
Physical Count Value in excess of the Basket will be paid to ESI out of the
Escrowed Property.

                  6.6.2 Receivables. If all accounts receivable reflected on the
Current Balance Sheet are collected when due, then the Basket will be increased
by up to $16,087, the amount of unreconciled accounts set forth on Schedule
3.1.27.

                                   ARTICLE VII

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; or

          (b) by ESI or Chip Star if any court of competent jurisdiction in the
United States or any state shall have issued an order, judgment or decree (other
than a temporary restraining order) restraining, enjoining or otherwise
prohibiting the Merger and such order, judgment or decree shall have become
final and nonappealable.

hereto (or any of its directors of officers) shall have any liability or further
obligation to any other party to this Agreement, except for breach of this
Agreement.

                               CALIFORNIA FORM OF
                            EMPLOYEE CONFIDENTIALITY
                            AND ASSIGNMENT AGREEMENT


     In consideration of my employment by Electro Scientific Industries, Inc.,
or by one of its subsidiaries and affiliates (herein collectively called "ESI"),
I agree to the following:

     1. Confidentiality. I acknowledge that my employment gives me access to
manufacturing processes, business plans, customer lists, drawings, documents,
reports, facilities, formulas, computer data, computer programs (including
algorithms, flowcharts, source code, object code and firmware), and other
information all of which ESI regards as confidential and treats as trade
secrets. I recognize that my employment creates a relationship of confidence and
trust which requires me to protect the secrecy of such confidential information.

     2. Nondisclosure and Nonuse. Except as the duties of my employment may
require, I will not use, publish or disclose any confidential information to
which I am given access. This obligation will continue even if I cease to be
employed by ESI. On termination of my employment, I shall deliver to ESI all
files, notes, records, data and documents which are under my control and which
relate to confidential information of ESI.

     3. Assignment of Inventions. I shall promptly disclose and I hereby assign
to ESI all proprietary rights, including any patents or copyrights which may be
obtained, in all inventions, processes, ideas, improvements, computer programs
embodied in any medium and at any stage of development (including but not
limited to algorithms, flowcharts, source code, object code and firmware), and
any other discoveries which are conceived by me, alone or with others, while I
am employed by ESI and for one year thereafter, and which relate to the business
of ESI (herein collectively called "the Inventions"). This obligation shall
apply even if the Inventions are not patentable and even if they were not
conceived during regular working hours.

     4. Patents and Copyrights. I shall cooperate fully with ESI during and
subsequent to my employment if ESI decides, at its expense, to obtain U.S. or
worldwide patents or copyrights covering my Inventions. If ESI elects not to
file patent or copyright applications within one year after I have submitted a
written disclosure on an Invention, and if ESI determines that the Invention
does not constitute a trade secret of ESI, the Invention will be released to me
with the retention by ESI of a transferable, nonexclusive and royalty-free
license under any patents or copyrights which may subsequently be issued.

     5. Bonus. If ESI elects to seek patent or copyright protection on any
Invention disclosed by me, it will pay me a bonus of $100.00 for each Invention
of which I am the sole inventor or my pro rata share of $100.00 if there are
multiple investors.
<PAGE>
     6. Prior Inventions. I have set out below a complete list of all
Inventions, if any, patented or unpatented, including the numbers of all patents
and patent applications filed thereon, and a brief description of all unpatented
Inventions, which I made prior to my employment by the Company, and which are to
be excluded from the scope of this Agreement. I agree that any patentable
improvements made upon the listed Inventions subsequent to my employment by the
ESI are to be the property of ESI if within the scope of Paragraph 3 hereof.

     7. I hereby irrevocably consent to and authorize the use and reproduction
by ESI or anyone authorized by ESI, of any and all photographs which are taken
of me during my employment by ESI, negative or positive, proofs of which will be
retained in ESI files, for any purpose whatsoever, without further compensation
to me. All negatives and positive, together with the prints shall constitute ESI
property, solely and completely.

     8. Litigation. I recognize that ESI will not have an adequate monetary
remedy to compensate it if I violate the terms of this Agreement. Accordingly,
if I fail to honor my obligations, I hereby consent to the immediate entry of a
temporary restraining order and preliminary injunction against me by a court of
competent jurisdiction. If any litigation is commenced to enforce this
Agreement, the prevailing party at trial and on appeal shall be entitled to an
award of reasonable attorneys' fees.

     9. Binding Effect. The provisions of this Agreement shall inure to the
benefit of and be binding upon the heirs, legal representatives, successors and
assigns of the parties.

Reserved Inventions (drawings, photographs, etc.; attached).

     Please note that Section 2870 of the California Labor Code provides that
the above Agreement between you and ESI does not require you to assign to ESI
any invention that you developed entirely on your own time without using ESI's
equipment, supplies, facilities, or trade secret information except for those
inventions that either: (i) relate at the time of conception or reduction to
practice of the invention to ESI's business, or actual or demonstrably
anticipated research or development of ESI, or (ii) result from any work
performed by you for ESI. By signing this Agreement, you acknowledge that this
paragraph shall constitute written notice of the provisions of Section 2870.

                           PLEDGE AND ESCROW AGREEMENT


     This PLEDGE AND ESCROW AGREEMENT (the "Agreement"), dated as of June 26,
1997, is among Electro Scientific Industries, Inc., an Oregon corporation
("ESI"), The First National Bank of Chicago, a national banking association
organized under the laws of the United States ("Escrow Agent"), and the
shareholders of Chip Star Inc., a California corporation ("Chip Star") listed on
Schedule A (the "Shareholders").

                                    RECITALS

     A. ESI, Chip Star, CI Merger Corp., an Oregon corporation ("Merger Corp."),
and the Shareholders are parties to an Agreement of Reorganization and Merger,
dated as of June 26, 1997 (the "Merger Agreement").

     B. Pursuant to the Merger Agreement, upon the merger of Merger Corp. into
Chip Star (the "Merger"), each Shareholder will be entitled to receive shares of
Common Stock, no par value, of ESI ("ESI Common Stock") in exchange for shares
of Common Stock, no par value, of Chip Star held by such Shareholder at the time
the Merger becomes effective (the "Effective Time").

     C. The Merger Agreement further provides that the Shareholders severally
will indemnify ESI and Merger Corp. as and to the extent provided in Article VI
of the Merger Agreement (the "Indemnities").

     D. To secure the performance of the Indemnities under the Merger Agreement,
the Merger Agreement provides that the Shareholders are to pledge and deposit 10
percent of the shares of ESI Common Stock to be issued to the Shareholders
pursuant to Section 1.3 of the Merger Agreement, to be held in escrow under this
Agreement (such shares of ESI Common Stock to be pledged, deposited, and held,
the "Escrow Shares").

     E. The Escrow Agent has agreed to hold the Escrow Shares pursuant to the
terms of this Agreement.

     F. It is a condition to the consummation of the transactions contemplated
by the Merger Agreement that the Shareholders and the Escrow Agent execute and
deliver to ESI and Merger Corp. this Agreement.

                                    AGREEMENT

     NOW, THEREFORE, the parties agree as follows:
<PAGE>
     1. Additional Definitions. In addition to the terms defined above, the
following terms have the indicated meanings:

          "Claim" has the meaning specified in Section 4.1.

          "Claim Notice" has the meaning specified in Section 4.1.

          "Indemnified Party" has the meaning specified in Section 4.1.

          "Proceeds" means, as to any given Escrow Share, any stock or
liquidating dividend, return of capital, or other distribution made on or in
respect of such Escrow Share, whether resulting from a subdivision, combination,
or reclassification of the outstanding capital stock of ESI or received in
exchange for such Escrow Share or as a result of any merger, consolidation,
acquisition or other exchange of assets to which ESI may be a party or
otherwise, provided that "Proceeds" will not include any non-liquidating
dividend payable in cash or property other than capital stock.

          "Valuation Price" means the closing per share selling price of ESI
Common Stock as reported in The Wall Street Journal on the date of this
Agreement, subject to appropriate adjustment in the event that, ESI:

          (a) declares a dividend payable in shares of its common stock;

          (b) splits or combines the shares of its common stock then
outstanding;

          (c) declares a distribution (other than a non-liquidating cash
dividend) on shares of its common stock;

          (d) merges or consolidates with any corporation in which ESI Common
Stock is exchanged or converted; or

          (e) reorganizes, recapitalizes or reclassifies any of the shares of
its common stock.

     2. Pledge and Acknowledgment; Deposit.

          2.1 Pledge and Acknowledgment. As security for the performance of the
Indemnities, the Shareholders hereby pledge the Escrow Shares, and consent to
the deposit with the Escrow Agent of certificates for the Escrow Shares,
together with stock powers endorsed to ESI, to be held and dealt with by the
Escrow Agent pursuant to the terms and subject to the conditions of this
Agreement. The Escrow Agent acknowledges receipt of a copy of the Merger
Agreement but, except for reference thereto for definitions of certain words or
terms not defined herein, the Escrow Agent is not charged with any duties or
responsibilities under the Merger Agreement.

                                        2
<PAGE>
          2.2 Deposit; Allocation of Payments. ESI will issue a certificate for
the Escrow Shares registered in the name of each Shareholder as set forth in
Schedule A, and will deposit all such certificates with the Escrow Agent on
behalf of each Shareholder. The interest in, and payments out of, the Escrow
Shares will be allocated among the Shareholders on a pro rata basis according to
the number of Escrow Shares set forth on Schedule A for each Shareholder except
as set forth in Section 4.5. Each Shareholder's interest in the Escrow Shares
will otherwise be uncertificated and nontransferable.

     3. Use of Escrow Shares and Proceeds. The Escrow Shares will remain
registered in the name of each Shareholder and, along with the Proceeds, will be
held in escrow (the "Escrow") by the Escrow Agent under this Agreement in
accordance with its terms.

     4. Disposition of Escrow Shares; Termination.

          4.1 Claim Notices. ESI, Merger Corp., and their respective officers,
directors, and shareholders (each, an "Indemnified Party") may, at any time or
from time to time for a period of 12 months following the Effective Time, assert
a claim for breach of a representation, warranty, or covenant of Chip Star
contained in the Merger Agreement in accordance with the procedure set forth in
Section 6.5 of the Merger Agreement (a "Claim") against the Escrow Shares by
notice (a "Claim Notice") to the Shareholders, with a copy to the Escrow Agent.
The Claim Notice must set forth in reasonable detail the basis for the Claim,
the nature of the damages, and the total dollar amount thereof, to the extent
known.

          4.2 Effect of Claim Notices. Upon receipt of a Claim Notice, the
Escrow Agent will designate as "Escrow Shares Subject to Claim" that number of
Escrow Shares that, based on the Valuation Price, is equal in value to the
estimate of the damages in the Claim Notice, or the remaining Escrow Shares if
such value is less than such estimate. Thereafter, the Escrow Agent will deliver
to ESI the Escrow Shares Subject to Claim not less than 40 days after delivery
of the Claim Notice, unless the Escrow Agent receives an objection from the
Shareholder pursuant to Section 4.3.

          4.3 Objections to Claims. If any Shareholder notifies the Escrow Agent
in writing of his good faith objections to any Claim Notice within 30 days
following delivery of such Claim Notice pursuant to Section 4.1, then the Escrow
Agent will instead hold such Escrow Shares Subject to Claim in Escrow until
either (a) the Shareholder and ESI have agreed upon the disposition of such
Escrow Shares with respect to such Claim Notice and notified the Escrow Agent of
such an agreement in writing signed by Shareholder and by ESI or (b) such
disposition is finally determined by binding arbitration pursuant to Section 4.4
and the Escrow Agent receives written notice of the final determination made by
the arbitrator in such arbitration.

          4.4 Dispute Resolution. If ESI and the Shareholder are unable, within
60 days after delivery of the written objection under Section 4.3, to agree upon
the disposition of the applicable Escrow Shares Subject to Claim, the dispute
will be resolved by binding

                                        3
<PAGE>
arbitration in San Francisco, California, conducted in accordance with the rules
and procedures of the American Arbitration Association.

          4.5 Disposition of Escrow Shares. At the end of the 12-month period
following the Effective Time, the Escrow Agent will, within five business days,
deliver to the Shareholders stock certificates equal to the number of Escrow
Shares then remaining in Escrow. Such Escrow Shares will be distributed pro rata
to the Shareholders in accordance with the number of Escrow Shares originally
deposited into Escrow as set forth on Schedule A.

          4.6 Escrow Shares Subject to Any Claim. Any Escrow Shares Subject to
Claim will be retained in Escrow and will be held by the Escrow Agent subject to
the terms and conditions of this Agreement and upon resolution of any such
pending Claims, stock certificates for the Escrow Shares not required to satisfy
such Claims (together with any Escrow Shares remaining in Escrow due to the
effect of the rounding provisions of Section 4.8) will be delivered to the
Shareholders, pro rata in accordance with the number of Escrow Shares originally
deposited into Escrow as set forth in Schedule A.

          4.7 Proceeds. Upon the delivery of any Escrow Shares to either ESI or
the Shareholders as provided in this Section 4, the Escrow Agent will deliver to
the party receiving such Escrow Shares the Proceeds relating to such Escrow
Shares.

          4.8 No Fractional Escrow Shares. Should any fractional share result
from the calculations described in this Section 4, the number of Escrow Shares
affected will be rounded to the nearest whole number.

          4.9 Third Party Claims. If any Claim Notice specifies that the
applicable Claim arises as a result of a claim asserted against the Indemnified
Party by a third party, the Escrow Shares will be subject to being used to
satisfy the expenses of the Indemnified Party defending against such claim,
provided, that if notice of objections to such Claim Notice is given pursuant to
Section 4.3, Escrow Shares will be available to satisfy such expenses only if
such objections are resolved in favor of release of Escrow Shares pursuant to
Section 4.3 or 4.4.

          4.10 Termination. This Agreement will terminate upon the delivery of
all of the Escrow Shares and Proceeds.

     5. Dividends and Proxies with respect to Escrow Shares. So long as any
Escrow Shares are held by the Escrow Agent hereunder:

          (a) Each Shareholder will be entitled to exercise any and all voting
     and consensual rights and powers accruing to such Shareholder with respect
     to his, her, or its Escrow Shares.

                                        4
<PAGE>
          (b) Each Shareholder will be entitled to receive any and all
     non-liquidating dividends payable in respect of his, her, or its Escrow
     Shares, which dividends will be paid directly by ESI to such Shareholder.
     All Proceeds in respect of the Escrow Shares, including stock dividends in
     respect of any Escrow Shares, will be delivered to and retained by the
     Escrow Agent and will not be distributed except in accordance with the
     terms of this Agreement.

     6. Stock Powers. Each Shareholder will sign and deliver to the Escrow Agent
stock powers endorsed to ESI to permit the Escrow Agent to transfer to ESI the
number of Escrow Shares determined in accordance with the provisions of Section
4.

     7. Escrow Agent Provisions.

          7.1 Investment Instructions. The Escrow Agent will invest and reinvest
the cash funds in Escrow, if any, in the Pegasus Institutional U.S. Government
Securities Cash Management Fund, which invests in short term securities issued
or guaranteed as to principal and interest by the U.S. Government and repurchase
agreements with respect to such securities. No such investment by the Escrow
Agent may have a maturity that exceeds the shorter of (a) one year from the date
of purchase or (b) such period of time as remains between the date upon which
the investment is made and the remaining term of this Agreement. Interest and
other earnings on the cash invested will be added to the cash in Escrow to be
held and distributed in accordance with Section 4. Any loss incurred from an
investment will be borne by the Escrow. Investment and reinvestment of the cash
in Escrow may be made only in accordance with this Section 7.1.

          7.2 Limited to Agreement. The duties and obligations of the Escrow
Agent hereunder will be determined solely by the express provisions of this
Agreement, and the Escrow Agent is under no obligation to refer to any other
documents between or among the parties related in any way to this Agreement.

          7.3 Exculpation. The Escrow Agent will not be liable to anyone
whomsoever by reason of any error of judgment, or for any act done or step taken
or omitted by it, or for any mistake of fact or law, or for anything that it may
do or refrain from doing in connection herewith unless in any such case caused
by or arising out of its own gross negligence or willful misconduct. The Escrow
Agent may act pursuant to the advice of the Escrow Agent's counsel with respect
to any matter relating to this Agreement and will not be liable for any action
taken or omitted by it in good faith in accordance with such advice. ESI will
indemnify and hold the Escrow Agent harmless from and against any and all
liability and expense that may arise out of any action taken or omitted by the
Escrow Agent in accordance with this Agreement, except such liability and
expense as may result from the gross negligence or willful misconduct of the
Escrow Agent. The indemnities in this Section 7.3 will survive the termination
of this Agreement.

          7.4 Reliance. The Escrow Agent is entitled to rely on, and will be
protected in acting in reliance upon, any instructions or directions furnished
to it in writing

                                        5
<PAGE>
signed by both ESI and a Shareholder pursuant to any provision of this Agreement
and will be entitled to treat as genuine, and as the document it purports to be,
any letter, paper, or other document that is furnished to it by either ESI or a
Shareholder and that the Escrow Agent reasonably believes to be genuine and to
have been signed and presented by the proper party or parties.

     8. Compensation of Escrow Agent. ESI will pay the Escrow Agent the fees and
expenses payable in accordance with Schedule 8 attached hereto, including its
attorney's fees and expenses, that it incurs in connection with the performance
of its duties under this Agreement, or under the indemnity provided in Section
7.3.

     9. Expenses. Any stock transfer taxes incurred in connection with the
release and delivery of any Escrow Shares by the Escrow Agent under this
Agreement will be borne by the recipient of such Escrow Shares.

     10. Notices. All notices required or permitted to be given hereunder must

return receipt requested, or when received if given by Federal Express or other
nationally recognized overnight courier service, or five business days after
being deposited in the United States mail, postage prepaid, registered or

          If to a Shareholder addressed to him at the appropriate address shown
     on Schedule A, and/or such other respective addresses and/or addressees as
     may be designated by notice given in accordance with the provisions of this
     Section 10.

     11. Taxes. As between each Shareholder and ESI in connection with this
Escrow, such Shareholder will be treated as the grantor thereof for tax purposes
and will include in such Shareholder's tax return his, her, or its share of any
earnings of the Escrow and pay any taxes incurred in connection therewith.

     12. 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

     13. 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.

     14. Amendment; Waiver. The provisions of this Agreement may be amended or
waived only by an instrument in writing signed by each of ESI, the Escrow Agent,
and each of the Shareholders.

     15. Counterparts. This Agreement may be executed in two or more
counterparts, each of which will be deemed to be an original but all of which
together will constitute one and the same Agreement.

     16. Transfer of Escrow Shares. The Shareholders acknowledge and understand
that the Escrow Shares have not been registered under the Securities Act of 1933
(the "Act") or any state securities laws, and that the transfer of the Escrow
Shares is therefore restricted. The Escrow Shares are also subject to certain
restrictions because they have been issued in a business combination accounted
for as a pooling of interests (the "Pooling Restrictions"). Each of the
foregoing restrictions is described in Section 1.8 of the Merger Agreement and
in the legends printed on certificates representing the Escrow Shares. The
Escrow Shares (i) can only be transferred if they are registered under the Act
and any state securities laws or there is an available exemption from such
registration and (ii) can only be sold (and the holder thereof may only reduce
his risk relative thereto) after ESI has published financial results covering at
least 30 days of combined operations following the Effective Time of the Merger.
In the event an exemption becomes available or the Escrow Shares are registered

                                        7
<PAGE>
under the Act during the term of this Agreement and after the Pooling
Restrictions have lapsed, thereby permitting the transfer of such shares, ESI
will notify the Escrow Agent to this effect, and ESI, the Shareholders and the
Escrow Agent agree to amend this Agreement to provide that, subject to
compliance with all procedural requirements requested by the Escrow Agent, (i) a
Shareholder may direct the Escrow Agent to transfer the Escrow Shares for value,
(ii) upon transfer, any value received for such Escrow Shares in excess of the
Valuation Price will be promptly distributed to the Shareholder, and (iii) an
amount equal to the Valuation Price will be retained by the Escrow Agent to
satisfy Claims for the term of this Agreement.

                                        8

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the day
and year first written above.

                  NONCOMPETITION AND NONSOLICITATION AGREEMENT


          This NONCOMPETITION AND NONSOLICITATION AGREEMENT (the "Agreement"),
dated as of June 26, 1997, is among Electro Scientific Industries, Inc., an
Oregon corporation ("ESI"), CI Merger Corp., an Oregon corporation ("Merger
Corp."), a wholly-owned subsidiary of ESI and ___________________ ("Selling
Shareholder").

                                    RECITALS

          A. Selling Shareholder owns shares in Chip Star, Inc., a California
corporation ("Chip Star").

          B. ESI, Chip Star, Merger Corp. and the shareholders of Chip Star have
entered into an Agreement of Reorganization and Merger (the "Merger Agreement"),
dated as of June 26, 1997, providing for the merger (the "Merger") of Merger
Corp. into Chip Star, with Chip Star as the surviving corporation ("New Chip
Star").

          C. Selling Shareholder is entering into this Agreement as an
inducement to ESI and Merger Corp. to consummate the Merger, with all of the
attendant financial benefits to Selling Shareholder from the disposition of his
capital stock of Chip Star.

                                    AGREEMENT

          The parties agree as follows:

          1. Acknowledgements by Selling Shareholder. Selling Shareholder
acknowledges that by virtue of his relationship with Chip Star, he has developed
considerable technical expertise in the design, manufacture and sale of the
equipment designed, manufactured and sold by Chip Star and considerable
expertise in the business operations of Chip Star and has access to extensive
confidential information with respect to Chip Star. Selling Shareholder
recognizes that ESI and Merger Corp. would be irreparably damaged, and ESI's
substantial investment in New Chip Star materially impaired, if Selling
Shareholder were to enter into an activity competing with any business of New
Chip Star in violation of the terms of this Agreement. Accordingly, Selling
Shareholder expressly acknowledges that he is voluntarily entering into this
Agreement and that the terms and conditions of this Agreement are fair and
reasonable to Selling Shareholder in all respects.

          2. Noncompetition. Until five years after the effective date of the
Merger, Selling Shareholder shall not, directly or indirectly, without the prior
written consent of ESI, engage or be engaged, in any capacity, directly or
indirectly, including but not limited as an employee, agent, consultant,
manager, executive, owner, lender or stockholder in any business entity engaged
in competition with any business conducted by Chip Star or New Chip Star at the
effective time of the Merger in any geographic location at which business was
conducted by Chip Star or New Chip Star
<PAGE>
at the effective time of the Merger. Notwithstanding the above, Selling
Shareholder shall not be deemed to be engaged directly or indirectly in any
business in contravention of the preceding sentence if he participates in any
such business solely as a passive investor of up to 1 percent of the equity
securities of a company or partnership, the securities of which are publicly
traded.

          3. Noninterference. Selling Shareholder further agrees that until five
years after the Closing Date, he will not, without the prior written consent of
ESI, (a) interfere with the business of New Chip Star by soliciting, attempting
to solicit, inducing, or otherwise causing any employee of New Chip Star to
terminate his or her employment as such in order to become an employee,
consultant or independent contractor to or for any competitor of New Chip Star
or to or for any company with which Selling Shareholder is associated in any
way; or (b) induce or attempt to induce any supplier of New Chip Star, or any
customers, distributors, resellers, or independent contractors of New Chip Star
to terminate their relationships with, or to take any action that would be
disadvantageous to the business of, New Chip Star.

          4. Independence of Obligations. The covenants of Selling Shareholder
set forth in this Agreement shall be construed as independent of any other
agreement or arrangement between Selling Shareholder, New Chip Star, or ESI and
any of its subsidiaries and the existence of any claim or cause of action by
Selling Shareholder against New Chip Star or ESI or any of its subsidiaries
shall not constitute a defense to the enforcement of this Agreement against
Selling Shareholder.

          5. Equitable Relief. Selling Shareholder expressly acknowledges that
damages alone will not be an adequate remedy for any breach by Selling
Shareholder of the covenants set forth in Sections 2 and 3 hereof and that the
other parties hereto, in addition to any other remedies which they may have,
shall 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 Selling Shareholder of any of such covenants.

          7. Severability. If any provision of this Agreement shall be held by a
court of competent jurisdiction to be excessively broad as to duration, activity
or geographic scope, it shall be deemed to extend only over the maximum
duration, activity or geographic scope as to which such provision shall be valid
and enforceable under applicable law. If any provisions shall, for any reason,
be held by a court of competent jurisdiction to be invalid, illegal or
unenforceable, such invalidity, illegality or unenforceability shall not affect
any other provision of this Agreement, but this Agreement shall be construed as
if such invalid, illegal or unenforceable provision had never been contained
herein.

          8. Effectiveness. This Agreement shall become effective only upon the
effective time of the Merger. If the Merger is not consummated and the Merger
Agreement is terminated, this Agreement shall be terminated and shall be without
force or effect.

          9. Notices. All notices or other communications hereunder shall be in
writing and deemed given if and when delivered to a party in person, or if and
when mailed by registered or

                                        2

          10. Waiver of Breach. The failure or delay by ESI or New Chip Star in
enforcing any provision of this Agreement shall not operate as a waiver thereof,
and any waiver shall not operate or be construed as a waiver of any subsequent
breach or violation thereof. All waivers shall be in writing and signed by the
party to be bound.

          11. Assignment; Binding Effect. This Agreement is not assignable by
Selling Shareholder. This Agreement shall be binding upon and inure to the
benefit of ESI, Merger Corp. and their respective successors and assigns.

          12. Entire Agreement; Amendment. This Agreement represents the entire
agreement and understanding of the parties with respect to the subject matter
hereof and supersedes all prior agreements and understandings of the parties in
connection therewith. This Agreement may not be altered or amended except by an
agreement in writing signed by the parties to be bound.

with the laws of the State of Oregon, exclusive of choice of law rules.

Arthur Andersen LLP
Suite 1400
111 SW Columbia Street
Portland, Oregon   97201-5875

Gentlemen:

This letter is being delivered to you pursuant to Section 4.1.4 of the Agreement
of Reorganization and Merger (the "Agreement"), dated as of June 26, 1997, among
Electro Scientific Industries, Inc. an Oregon corporation ("Parent"), CI Merger
Corp., an Oregon corporation and a wholly owned subsidiary of Parent ("Merger
Corp."), Chip Star Inc., a California corporation (the "Company"), and Denver
Braden and Angelo Mitchell, the principal shareholders of Chip Star (the
"Shareholders"). Unless otherwise indicated, capitalized terms not defined
herein have the meaning set forth in the Agreement.

After due inquiry and investigation regarding the meaning of and factual support
for the following representations, the undersigned hereby certifies and
represents that the following facts are true:

     1. Pursuant to the Merger, Merger Corp. will merge with and into the
Company, and the Company will acquire all of the assets and liabilities of
Merger Corp.. Specifically, the assets transferred to the Company pursuant to
the Merger will represent at least ninety percent (90%) of the fair market value
of the net assets and at least seventy percent (70%) of the fair market value of
the gross assets held by Merger Corp. immediately prior to the Merger. In
addition, at least ninety percent (90%) of the fair market value of the net
assets and at least seventy percent (70%) of the fair market value of the gross
assets held by the Company immediately prior to the Merger will continue to be
held by the Company immediately after the Merger. For the purpose of determining
the percentage of the Company's and Merger Corp.'s net and gross assets held by
the Company immediately following the Merger, the following assets will be
treated as property held by Merger Corp. or the Company, as the case may be,
immediately prior but not subsequent to the Merger: (i) assets used by the
Company or Merger Corp. (other than assets transferred from Parent to Merger
Corp. for such purpose) to pay shareholders perfecting dissenters' rights or
other expenses or liabilities incurred in connection with the Merger and (ii)
assets used to make distributions, redemptions or other payments in respect of
stock of the Company (except for regular, normal distribution) or in respect of
rights to acquire such stock (including payments treated as such for tax
purposes) that are made in contemplation of the Merger or that are related
thereto;

     2. Merger Corp. was formed solely for the purpose of consummating the
transactions contemplated by the Agreement and at no time will Merger Corp.
conduct any business activities or other operations, or dispose of any of its
assets, other than pursuant to its obligations under the Agreement;

     3. Parent's principal reasons for participating in the Merger are bona fide
business purposes not related to taxes;

     4. Prior to the Merger, Parent will be in "Control" of Merger Corp.. As
used in this letter, "Control" shall consist of direct ownership of share of
stock possessing at least eighty percent (80%) of the total combined voting
power of all classes of stock entitled to vote and at least eighty percent (80%)
of the total number of shares of all other classes of stock of the corporation.
For purposes of 
<PAGE>
determining Control, a person shall not be considered to own shares of voting
stock if rights to vote such shares (or to restrict or otherwise control the
voting of such shares) are held by a third party (including a voting trust)
other than an agent of such person;

     5. In the Merger, shares of stock of the Company representing Control of
the Company will be exchanged solely for shares of voting stock of Parent. For
purposes of this paragraph, shares of stock of the Company exchanged in the
Merger for cash and other property (including, without limitation, cash paid to
shareholders of the Company perfecting dissenters' rights) will be treated as
shares of stock of the Company outstanding on the date of the Merger but not
exchanged for shares of voting stock of Parent;

     6. Parent has no plan or intention to cause the Company to issue additional
shares of stock after the Merger, or take any other action, that would result in
Parent losing Control of the Company;

     7. Parent has no plan or intention to reacquire any of its stock issued
pursuant to the Merger;

     8. Parent has no plan or intention to liquidate the Company; to merge the
company with or into another corporation, including Parent or its affiliates; to
sell, distribute or otherwise dispose of the stock of the Company; or to cause
the Company to sell or otherwise dispose of any of its assets or of any assets
acquired from Merger Corp., except for dispositions made in the ordinary course

Arthur Andersen LLP
Suite 1400
111 SW Columbia Street
Portland, Oregon   97201-5875

Gentlemen:

This letter is being delivered to you pursuant to Section 4.1.4 of the Agreement
of Reorganization and Merger (the "Agreement"), dated as of June 26, 1997, among
Electro Scientific Industries, Inc. an Oregon corporation ("Parent"), CI Merger
Corp., an Oregon corporation and a wholly owned subsidiary of Parent ("Merger
Corp."), Chip Star Inc., a California corporation (the "Company"), and Denver
Braden and Angelo Mitchell, the principal shareholders of Chip Star (the
"Shareholders"). Unless otherwise indicated, capitalized terms not defined
herein have the meaning set forth in the Agreement.

After due inquiry and investigation regarding the meaning of and factual support
for the following representations, the undersigned hereby certifies and
represents that the following facts are true:

     1. Pursuant to the Merger, Merger Corp. will merge with and into the
Company, and the Company will acquire all of the assets and liabilities of
Merger Corp.. Specifically, the assets transferred to the Company pursuant to
the Merger will represent at least ninety percent (90%) of the fair market value
of the net assets and at least seventy percent (70%) of the fair market value of
the gross assets held by Merger Corp. immediately prior to the Merger. In
addition, at least ninety percent (90%) of the fair market value of the net
assets and at least seventy percent (70%) of the fair market value of the gross
assets held by the Company immediately prior to the Merger will continue to be
held by the Company immediately after the Merger. For the purpose of determining
the percentage of the Company's and Merger Corp.'s net and gross assets held by
the Company immediately following the Merger, the following assets will be
treated as property held by Merger Corp. or the Company, as the case may be,
immediately prior but not subsequent to the Merger: (i) assets used by the
Company or Merger Corp. (other than assets transferred from Parent to Merger
Corp. for such purpose) to pay shareholders perfecting dissenters' rights or
other expenses or liabilities incurred in connection with the Merger and (ii)
assets used to make distributions, redemptions or other payments in respect of
stock of the Company (except for regular, normal distributions) or in respect of
rights to acquire such stock (including payments treated as such for tax
purposes) that are made in contemplation of the Merger or that are related
thereto;

     2. Other than in the ordinary course of business or pursuant to its
obligations under the Agreement, the Company has not disposed of any of its
assets (including any distribution of assets with respect to, or in redemption
of, stock) since commencement of negotiations with Parent regarding the Merger;

     3. The Company's principal reasons for participating in the Merger are bona
fide business purposes unrelated to taxes;

     4. The Company has no outstanding warrants, options, convertible securities
or any other type of right to acquire the Company stock (or any other equity
interest in the Company) or to vote (or restrict or otherwise control the vote
of) shares of stock of the Company which, if exercised, would affect Parent's
acquisition and retention of Control of the Company;
<PAGE>
     5. In the Merger, shares of stock of the Company representing "Control" of
the Company will be exchanged solely for shares of voting stock of Parent. For
purposes of this paragraph, shares of the stock of Company exchanged in the
Merger for cash and other property (including, without limitation, cash paid to
shareholders of the Company perfecting dissenters' rights) will be treated as
shares of stock of the Company outstanding on the date of the Merger but not
exchanged for shares of voting stock of Parent. As used in this letter,
"Control" shall consist of direct ownership of shares of stock possessing at
least eighty percent (80%) of the total combined voting power of all classes of
stock entitled to vote and eighty percent (80%) of the total number of shares of
all other classes of stock of the corporation. For purposes of determining
Control, a person shall not be considered to own share of voting stock if rights
to vote such shares (or to restrict or otherwise control the voting of such
shares) are held by a third party (including a voting trust) other than an agent
of such person;

     6. The Company has no plan or intention to issue additional shares of stock
after the Merger, or take any other action, that would result in Parent losing
Control of the Company;

     7. The Company has no plan or intention to sell or otherwise dispose of any
of its assets or of any of the assets acquired from Merger Corp. in the Merger
except for dispositions made in the ordinary course of business or payment of
expenses, including payments to shareholders of the Company perfecting
dissenters' rights, incurred by the Company pursuant to the Merger and except
for transfers described in both Section 368(a)(2)(C) of the Code and Treasury
Regulation Section 1.368-2(j)(4);

     8. Following the Merger, the Company will continue its historic business or
use a significant portion of its historic business assets in a business;

     9. The fair market value of the Company's assets will, at the Effective
Time of the Merger, exceed the aggregate liabilities of the Company plus the
amount of liabilities, if any, to which such assets are subject;

     10. The Company is not an "investment company" within the meaning of
Sections 368(a)(2)(F)(iii) and (iv) of the Code;

     11. The Company has not been a United States real property holding
corporation within the meaning of Section 897(c)(2) of the Code during the
applicable period specified in Section 897(c)(1)(A)(ii) of the Code;

     12. The Company is not under the jurisdiction of a court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code;

     13. There is no plan or intention ("Plan") on the part of the shareholders
of the Company who own one percent or more of the Company stock and, after due
inquiry with its officers and directors, the Company has no knowledge of, and
believes that there does not exist, any Plan on the part of the remaining
shareholders of the Company to engage in a sale, exchange, transfer,
distribution (including, without limitation, a distribution by a corporation to
its stockholders), pledge, disposition or any other transaction which results in
a reduction in the risk of ownership or a direct or indirect disposition (a
"Sale") of any shares of Parent stock received in the Merger that would reduce
ownership by the shareholders of the Company of Parent stock to a number of
shares having a value 
<PAGE>
as of the effective time of the Merger of less than fifty percent (50%) of the
aggregate fair market value, as determined immediately prior to the Merger, of
all outstanding shares of the Company stock. For purposes of this paragraph,
shares of the Company stock (i) with respect to which a shareholder of the
Company receives consideration in the Merger other than shares of Parent stock
(including, without limitation, cash received pursuant to the exercise of
dissenters' rights) and/or (ii) with respect to which a Sale occurs prior to,
and in contemplation of, the Merger, shall be considered outstanding shares of
stock of the Company exchanged for shares of Parent stock in the Merger and then
disposed of pursuant to a Plan;

     14. The fair market value of the shares of Parent stock received by each
shareholder of the Company will be approximately equal to the fair market value
of the shares of stock of the Company surrendered in exchange therefor and the
aggregate consideration received by shareholders of the Company in exchange for
their shares of stock in the Company will be approximately equal to the fair
market value of all of the outstanding shares of stock of the Company
immediately prior to the Merger;

     15. Merger Corp., Parent, the Company and the shareholders of the Company
will each pay separately its or their own expenses relating to the Merger;

     16. There is no intercorporate indebtedness existing between Parent and the
Company or between Merger Corp. and the Company that was issued, acquired, or
will be settled at a discount as a result of the Merger;

     17. The terms of the Agreement are the product of arm's-length
negotiations;

     18. None of the amounts received by any shareholder of the Company that
engages in any transaction with the Company other than in his or her capacity as
a shareholder will be separate consideration for, or allocable to, any of his or
her shares of stock of the Company; none of the shares of Parent stock received
by any such shareholder will be separate consideration for, or allocable to, any
employment agreement, any covenant not to compete, any lease, license or other
agreement or arrangement relating to the performance of services or transfer or
use of property (other than the shares of Company stock surrendered in the
Merger); and the amounts paid to any such shareholder will be for services
actually rendered or property actually acquired or used and will be commensurate
with amounts paid to third parties bargaining at arm's-length for similar
services or property;

     19. To the best knowledge of the Company, during the past five (5) years,
none of the outstanding shares of capital stock of the Company, including the
right to acquire or vote any such shares, have directly or indirectly been owned
by Parent;

     20. The Merger will qualify as a merger under State law;

     21. The Company is authorized to make all of the representations set forth
herein; and

     22. The Agreement represents the full and complete agreement among Parent,
Merger Corp. and the Company regarding the Merger, and there are no other
written or oral agreements regarding the Merger.

     It is understood that (i) your opinions will be based on the

Agreement (including all schedules and exhibits thereto) and documents related
thereto, and (ii) your opinions will be subject to certain limitations and
qualifications including that they may not be relied upon if any such
representations are not accurate in all material respects.

     Notwithstanding anything herein to the contrary, the undersigned makes no
representations regarding any actions or conduct of the Company pursuant to
Parent's exercise of control over the Company after the Merger. It is understood
that your opinions will not address any tax consequence of the Merger or any
action taken in connection therewith except as expressly set forth in such
opinions.

                                       Very truly yours,

    Re:  Agreement of Reorganization and Merger among Electro Scientific
         Industries, Inc., Chip Star Inc., CI Merger Corp. and Shareholders
         of Chip Star Inc.

Ladies and Gentlemen:

     We have acted as counsel for Chip Star Inc., a California corporation (the
"Company"), Denver Braden and Angelo Mitchell (together, the "Shareholders") in
connection with the Agreement of Reorganization and Merger dated as of June 26,
1997 (the "Merger Agreement"), among Electro Scientific Industries, Inc.
("ESI"), CI Merger Corp. ("Merger Corp."), the Company and the Shareholders,
providing, among other things, for the merger of Merger Corp. into the Company.
This opinion is furnished to you pursuant to Section 5.3.2 of the Merger
Agreement. Unless otherwise defined herein, capitalized terms used herein shall
have the same meanings assigned to them in the Merger Agreement.

     In connection with this opinion, we have examined and reviewed the Merger
Agreement, the Pledge and Escrow Agreement (the "Escrow Agreement") and the
documents delivered pursuant thereto and have taken such additional steps and
reviewed such additional documents and matters as we deemed necessary in order
to render our opinion.

     Based on the foregoing, and subject to the qualifications set forth below,
it is our opinion that:

     1. The Company is a corporation duly incorporated, existing and in good
standing under the laws of the state of its incorporation, and has all necessary
corporate power and authority under applicable corporate law and its
organizational documents to own or lease its properties and to carry on its
business as currently conducted.

     2. The authorized capital stock of the Company consists of 1,500,000 shares
of common stock, without par value ("Company Common Stock"). As of the date
hereof, there are 900,000 shares of Company Common Stock issued and outstanding
to the persons and in amounts set forth in Schedule 3.1.2 of the Merger
Agreement. All of the issued and outstanding capital stock of the Company has
been duly authorized and validly issued, is fully paid, nonassessable, and free
of preemptive rights. The Company's securities were issued in compliance with
available exemptions from registration under applicable securities laws. As of
the date hereof, there are not, except as disclosed in the Chip Star Disclosure
Schedule or the Merger Agreement, any outstanding subscriptions, options,
warrants, preemptive rights, stock appreciation rights, calls, rights,
convertible securities or other agreements or commitments of any character
relating to issued or unissued capital stock or other securities of the Company,
or otherwise obligating the Company to issue, transfer or sell any shares of the
capital stock of the Company, or other securities convertible into, exchangeable
for, or evidencing the right to subscribe for, any shares of the capital stock
of the Company.

     3. No consent, authorization, order or approval of, or filing or
registration with, any Governmental Entity is required for the execution and
delivery of the Merger Agreement by the Company and the Shareholders, the
execution and delivery of the Escrow Agreement by the Shareholders, or the
performance by the Company or any Shareholder of their respective obligations
contemplated by the Merger Agreement or the Escrow Agreement, other than filing
of the Articles of Merger with the Secretary of State of Oregon and the
Certificate of Merger with the Secretary of State of California.

     4. The Company has the corporate power and authority to enter into and
perform the Merger Agreement. The Company has taken all corporate action
necessary to authorize the execution and performance of the Merger Agreement and
the execution and delivery of the closing documents to be executed by it.

     5. The Merger Agreement has been duly executed and delivered by a duly
authorized officer of the Company and by each Shareholder. The Escrow Agreement
has been duly executed and delivered by each Shareholder. The Merger Agreement
is valid, binding and enforceable against the Company and each Shareholder and
the Escrow Agreement is valid, binding and enforceable against each Shareholder,
each in accordance with its terms, except as such enforceability may be limited
by or subject to any bankruptcy, insolvency, reorganization, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights and except
that the remedies of specific performance, injunction and other forms of
equitable relief are subject to certain tests of equity jurisdiction, equitable
defenses and the discretion of the court before which any proceeding therefor
may be brought.

     6. Neither the execution and delivery of the Merger Agreement by the
Company or the Shareholders nor the performance by the Company and the
Shareholders of the obligations therein contemplated will conflict with or
result in a breach of any of the terms, conditions or provisions of the
Company's Articles of Incorporation or Bylaws, or to the best of our knowledge,
of any statute or administrative regulation applicable to the Company, or, to
the best of our knowledge, of any writ, injunction, judgment or decree of any
court or any governmental authority or of any arbitration award binding upon the
Company or the Shareholders.

     7. Except as set forth in the Chip Star Disclosure Schedule, to the best of
our knowledge, there is no litigation or proceeding, in law or in equity, and
there are no proceedings or governmental investigations before any commission or
other administrative authority, pending or threatened, against the Company or
the Shareholders (a) which relate to the Company's business or operations and
which would, if decided adversely to the Company, have a material adverse
effect, or (b) which relate to the consummation of the transactions contemplated
by the Merger Agreement.

     8. Upon the consummation of the transactions and execution and delivery of
the documents contemplated by the Merger Agreement and the filing with the
Secretary of State of California of a Certificate of Merger in accordance with
the laws of the State of California, the Merger will have been validly effected
in accordance with the laws of the State of California.

     The opinions set forth above are subject to the following qualifications:

     1. We have assumed the genuineness of all signatures, the authenticity of
all documents submitted to us as originals, the conformity to the originals of
all documents submitted to us as copies and the authenticity of the originals of
all such latter documents.

     2. We have assumed the due execution and delivery for value of the Merger
Agreement and the Escrow Agreement by ESI or Merger Corp., as applicable and
each of the other documents delivered in connection therewith by each of the
parties thereto, other than the Company and the Shareholders.

     3. We have relied (to the extent we have no contrary knowledge), without
investigation, as to matters of fact upon certificates furnished by officers of
the Company whose positions and authority would reasonably require them to have
knowledge of the facts certified, and by governmental officials, and search
reports of recognized search companies.

made a special examination of any law other than the law of the State of
California and the federal law of the United States. Accordingly, in connection
with the rendering of this opinion, we express no opinion as to the laws of any
