AMENDED AND RESTATED PERFORMANCE-BASED

RESTRICTED STOCK UNIT AWARD AGREEMENT

This Amended and Restated Award Agreement (the Agreement) is entered into as of
, 2007 by and between Electro Scientific Industries, Inc., an Oregon corporation (the Company), and
 (Recipient), for the grant of restricted stock units with
respect to the Companys Common Stock (Common Stock).

On July 19, 2006, the Compensation Committee of the
Companys Board of Directors made a restricted stock units award to Recipient pursuant to the Companys 2004 Stock Incentive Plan (the Plan). The award is intended to qualify as performance-based compensation under
Section 162(m) of the Internal Revenue Code of 1986. Recipient desires to accept the award subject to the terms and conditions of this Agreement.

IN CONSIDERATION of the mutual covenants and agreements set forth in this Agreement, the parties agree to the following.

1. Grant and Terms of Restricted Stock Units. The Company grants to Recipient under the Plan  restricted stock units,
subject to the restrictions, terms and conditions set forth in this Agreement.

(a) Rights under Restricted Stock
Units. A restricted stock unit (a RSU) represents the unsecured right to require the Company to deliver to Recipient one share of Common Stock for each RSU. The number of shares of Common Stock deliverable with respect to each RSU is
subject to adjustment as determined by the Board of Directors of the Company as to the number and kind of shares of stock deliverable upon any merger, reorganization, consolidation, recapitalization, stock dividend, spin-off or other change in the
corporate structure affecting the Common Stock generally.

(b) Vesting. The RSUs issued under this Agreement shall
initially be 100% unvested and subject to forfeiture as set forth below.

(i) Except as set forth in Section 1(d), if
Recipient ceases to be employed by the Company for any reason or for no reason prior to the end of the Performance Period (as defined below), the unvested RSUs shall be forfeited to the Company.

(ii) To the extent that any of the RSUs first specified above are reduced in accordance with Section 1(b)(iii) upon achievement to
any extent of the Performance Goal (as defined below) and except as provided in Section 1(d), the unvested RSUs shall be forfeited to the Company. The extent to which the Performance Goal is achieved, if at all, shall be determined no later
than the date that the Companys Form 10-Q for the first quarter of fiscal year 2010 (the Determination Date) is filed. Nothing contained in this Agreement shall confer upon Recipient any right to be employed by the Company or to
continue to provide services to the Company or to interfere in any way with the right of the Company to terminate Recipients services at any time for any reason, with or without cause.

the peer group companies set forth on Exhibit A for the twelve-quarter period comprised of the three most recent fiscal years for which annual earnings information is available prior to the Determination Date (the Comparable
Period) as compared to the average earnings/(loss) per share for such company for the twelve-quarter period comprised of the three fiscal years preceding the Comparable Period. All information with respect to members of the peer group will be

exchange (an Exchange), any RSUs subject to this award that are unvested on the date of the Change in Control shall continue to vest according to the terms and conditions of this award; provided that such award is replaced with an award
for voting securities of the resulting corporation or the acquiring corporation, as the case may be (including without limitation, the voting securities of any corporation which as a result of the Change in Control owns the Company or all or
substantially all of the Companys assets either directly or through one or more subsidiaries) (the Surviving Company) which are traded on an Exchange (a Replacement Award), which Replacement Award shall consist of RSUs
with a value (determined using the Surviving Companys stock price as of the date of the Change in Control) equal to the value of the replaced award of RSUs (determined using the Companys stock price and assuming attainment of target
performance or actual performance achieved, if greater, as of the date of the Change in Control); provided, however, that in the event of a termination by the Company without Cause or by Recipient for Good Reason during the Performance Period, the
Replacement Award shall immediately vest and the shares shall be delivered as soon as practicable after the Determination Date, but in no event later than December 31 of the calendar year in which the Performance Period ends; and provided

Determination Date, but in no event later than December 31 of the calendar year in which the Performance Period ends, equal to the decrease, if any, in
the value of a share of the Surviving Companys stock from the date of the Change in Control (as increased on a calendar quarterly basis using an annual interest rate, as of the last business day of the calendar quarter, for zero-coupon U.S.
government securities with a constant maturity closest in length to the time period between the date of the Change in Control and the date of vesting of the Replacement Award) to the time of vesting multiplied by the total number of RSUs vesting on
such date. If any RSUs that are unvested at the time of the Change in Control are not replaced with Replacement Awards, the number of such RSUs shall immediately be adjusted based upon deemed attainment of target performance or actual performance
achieved, if greater, shall immediately become vested and be delivered as soon as practicable.

(2) If as a result of a
Change in Control, the Companys Common Stock continues to be listed for trading on an Exchange, any RSUs that are unvested on the date of the Change of Control shall continue to vest in accordance with the terms and conditions of this award;
provided however, that, in the event of a termination by the Company without Cause or by Recipient for Good Reason during the vesting period of this award such award shall immediately vest and the shares shall be delivered as soon as practicable
after the Determination Date, but in no event later than December 31 of the calendar year in which the Performance Period ends; and provided further that Recipient shall be entitled to receive a lump sum cash payment, paid as soon as
practicable after the Determination Date, but in no event later than December 31 of the calendar year in which the Performance Period ends, equal to the decrease, if any, in the value of a share of the Companys stock from the date of the
Change in Control (as increased on a calendar quarterly basis using an annual interest rate, as of the last business day of the calendar quarter, for zero-coupon U.S. government securities with a constant maturity closest in length to the time
period between the date of the Change in Control and the date of the vesting) to the time of vesting, multiplied by the total number of RSUs vesting on such date.

(3) For purposes of this Agreement, a Change in Control of the Company shall mean the occurrence of any of the following
events:

(A) Any consolidation, merger or plan of share exchange involving the Company (a Merger) as a result
of which the holders of outstanding securities of the Company ordinarily having the right to vote for the election of directors (Voting Securities) immediately prior to the Merger do not continue to hold at least 50% of the combined
voting power of the outstanding Voting Securities of the surviving or continuing corporation immediately after the Merger, disregarding any Voting Securities issued or retained by such holders in respect of securities of any other party to the
Merger;

(B) Any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all,
or substantially all, the assets of the Company;

Incumbent Directors then in office and voting (with new directors nominated or elected by two-thirds of the Incumbent Directors also being deemed to be Incumbent Directors); or

(E) Any Person (as hereinafter defined) shall, as a result of a tender or exchange offer, open market purchases, or privately negotiated
purchases from anyone other than the Company, have become the beneficial owner (within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934), directly or indirectly, of Voting Securities representing fifty percent (50%) or more
of the combined voting power of the then outstanding Voting Securities.

Notwithstanding anything in the foregoing to the contrary, unless otherwise
determined by the Board of Directors, no Change in Control shall be deemed to have occurred for purposes of this Agreement if (1) Recipient acquires (other than on the same basis as all other holders of the Company Common Stock) an equity
interest in an entity that acquires the Company in a Change in Control otherwise described under subparagraph (A) or (B) above, or (2) Recipient is part of group that constitutes a Person which becomes a beneficial owner of Voting
Securities in a transaction that otherwise would have resulted in a Change in Control under subparagraph (E) above.

(4) For purposes of this Agreement, the term Person shall mean and include any individual, corporation, partnership, group, association or other person, as such term is used in Section 14 (d) of the
Securities Exchange Act of 1934 (the Exchange Act), other than the Company, a wholly owned subsidiary of the Company or any employee benefit plan(s) sponsored by the Company.

(5) For purposes of this Agreement, termination by Recipient of his or her employment for Good Reason shall mean termination

Recipients status, title, position(s) and responsibilities as in effect immediately prior to the Change in Control or the assignment to Recipient of any duties or responsibilities which are inconsistent with such status, title, position(s) or
responsibilities (in either case other than is isolated, insubstantial or inadvertent actions which are remedied after notice), or any removal of Recipient from such position(s), except in connection with the termination of Recipients

employees); or

(C) the Companys or Surviving Companys requiring Recipient to be based more than fifty miles
from the principal office at in which Recipient is based immediately prior to the Change in Control, except for reasonably required travel on the Companys business.

(g) Delivery on Delivery Date. As soon as practicable following the delivery date for a RSU, the Company shall deliver a certificate for the number of shares represented by all vested RSUs having a delivery
date on the same date, rounded down to the whole share. No fractional shares of Common Stock shall be issued. The Company shall pay to Recipient in cash an amount equal to the value of any fractional shares that would otherwise have been issued,
valued as of the delivery date.

(h) Recipients Rights as Shareholder. Recipient shall have no rights as a
shareholder with respect to the RSUs or the shares underlying them until the Company delivers the shares to Recipient on the delivery date.

(i) Tax Withholding. Recipient acknowledges that, at the delivery date, the value of such vested RSUs will be treated as ordinary compensation income for federal and state income and FICA tax purposes, and that
the Company will be required to withhold taxes on this income amount. Promptly following the delivery date, the Company will notify Recipient of the required withholding amount. Concurrently with or prior to the delivery of the certificate referred
to in Section 1(g), Recipient shall pay to the Company the required withholding amount in cash or, at the election of the Recipient (which election must be made on or before the Determination Date), by surrendering to the Company for
cancellation shares of the Companys Common Stock to be issued with respect to the RSUs or other shares of the Companys Common Stock valued at the closing market price for the Companys Common Stock on the Determination Date. If the
