3. ENTITLEMENT UPON TERMINATION BY ASYST WITHOUT CAUSE OR BY THE EXECUTIVE FOR GOOD REASON
WITHIN TWO YEARS FOLLOWING A CHANGE IN CONTROL. In the event of termination of the Executives employment within two years following a Change
in Control (a) by Asyst without Cause or (b) by the Executive for Good Reason, he shall be entitled
to the following (such amounts to be paid to the Executive in a cash lump sum within 30 business
days after termination): (a) General Entitlement: (i) his Base Salary through the date of termination, but not yet paid to him; (ii) payment in lieu of any unused vacation, in accordance with Asysts vacation policy and
applicable laws; (iii) any annual or discretionary bonus earned but not yet paid to him for any completed
fiscal year prior to the fiscal year in which his termination occurs; (iv) any compensation under any deferred compensation plan of Asyst or deferred compensation

##### 



(vi) reimbursement of any business expenses reasonably and properly incurred by the Executive

termination, and (B) an amount equal to the average of his annual bonuses actually paid by Asyst to
the Executive during the three completed fiscal years prior to the year in which termination
occurs; (ii) continuing coverage under the life, disability, accident, health, dental and vision
insurance programs covering senior executives of Asyst generally, as from time to time in effect,
to the extent permitted under COBRA coverage or the terms of other such programs, for the two-year
period from such termination, or, if earlier, through such date as he becomes eligible for
substantially similar coverage under the employee benefit plans of a new employer; and (iii) immediate and unconditional vesting of any unvested stock options and stock grants
previously awarded to the Executive and, for the one-year period following termination, the right
to exercise the all such stock options, grants and awards vested as of the termination of
employment. (c) Determination of Amount of Payment.In the event that any payments or other benefits
received or to be received by the Executive pursuant to this Agreement (Payments) would (i)
constitute a parachute payment within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the Code) and (ii) but for this Section 3(c), be subject to the excise tax
imposed by Section 4999 of the Code (the Excise Tax), then, in accordance with this Section 3(c),
such Payments shall be reduced to the maximum amount that 6




---



##### 



would result in no portion of the payments being subject to the Excise Tax, but only if and to
the extent that such a reduction would result in the Executives receipt of Payments that are
greater than the net amount that he would receive hereunder (after application of the Excise Tax)
if no reduction were made. The amount of required reduction, if any, shall be the smallest amount so that the Executives
net proceeds with respect to the Payments (after taking into account payment of any Excise Tax)
shall be maximized, as determined by him. The Executives reasonable determination of any required
reduction pursuant to this Section 3(c) shall be conclusive and binding upon Asyst. Asyst shall
reduce Payments in accordance with this Section 3(c) only upon written notice from the Executive
indicating the amount of such reduction, if any. If the Internal Revenue Service (the IRS)
determines that a Payment is subject to the Excise Tax, then the following paragraph shall apply. Notwithstanding any reduction described in the immediately preceding paragraph (or in the
absence of any such reduction), if the IRS determines that the Executive is liable for the Excise
Tax as a result of the receipt of Payments, then he shall be obligated to pay back to Asyst, within
30 days after final IRS determination, an amount of the Payments equal to the Repayment Amount.
The Repayment Amount shall be the smallest such amount, if any, as shall be required to be paid to
Asyst so that the Executives net proceeds with respect to the Payments (after taking into account
the payment of the Excise Tax imposed on such Payments) shall be maximized. Notwithstanding the
foregoing, the Repayment Amount shall be zero if a Repayment Amount of more than zero would not
eliminate the Excise Tax imposed on the Payments. If the Excise Tax is not eliminated pursuant to
this paragraph, the Executive shall pay the Excise Tax. 7

(d) Release.Asyst may require, as a condition of receiving the foregoing Change-in-Control
payment or other Payment under subsection (b) or (c) above, that the Executive execute in
conjunction with his termination a general release substantially in the form annexed hereto as
Exhibit A (subject to such reasonable changes as may be required by circumstances or
changes in applicable law as are necessary to give effect to the same), which upon execution shall
be deemed incorporated herein by reference as a material part of this Agreement. 4. NO MITIGATION. Asyst agrees that if the Executives employment with Asyst terminates, he shall not be
obligated to seek other employment or to attempt to reduce any amount payable to him under this
Agreement. Further, no amount of any payment hereunder shall be reduced by any compensation earned
by the Executive as the result of employment by a subsequent employer or otherwise. 5. NOTICES. Any notice or other communication required or permitted under this Agreement shall be in
writing and shall be deemed to have been duly given when delivered by hand, electronic transmission
(with a copy following by hand or by overnight courier), by registered or certified mail, postage
prepaid, return receipt requested or by overnight courier addressed to the other party. All notices
shall be addressed as follows, or to such other address or addresses as may be substituted by
notice in writing: To Asyst :

amendment, modification or waiver shall be agreed to in writing and signed by the Executive and by
the Compensation Committee of the Board. (b) Severability.If any provision of this Agreement shall be determined to be invalid or
unenforceable by a court of competent jurisdiction, the remaining provisions of this Agreement
shall be unaffected thereby and shall remain in full force and effect to the fullest extent
permitted by law. (c) Partial Invalidity.If any provision of this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable, the remaining provisions shall nevertheless
continue in full force without being impaired or invalidated in any way. (d) Governing Law.This Agreement shall be construed, interpreted and governed in accordance
with the laws of the State of California, without reference to rules relating to conflicts of law. (e) Inconsistencies.The terms of this Agreement supersede any inconsistent prior promises,
policies, representations, understandings, arrangements or agreements between the parties, whether

obligations of Asyst, if any, following the termination of the Executives employment following a

##### 



(g) Withholding.Asyst may deduct and withhold from any payments hereunder the amount that
Asyst, in its reasonable judgment, is required to deduct and withhold for any federal, state or
local income or employment taxes. (h) No Other Compensation; Employee at Will.Except and to the extent specifically provided
in Section 3 above, no amount or benefit shall be due or payable to the Executive, and no
obligation or liability due or owing by Asyst, under this Agreement or otherwise in respect of
termination of his employment (at any time or within two years following a Change in Control).
This Agreement shall not be construed as creating an express or implied contract of employment and,
except and to the extent specifically otherwise agreed in writing between the Executive and Asyst,
the Executive is and shall remain an employee at will and shall not have any right or expectation
(reasonable or otherwise) to be retained or continue in the employ of Asyst. (i) Arbitration.Any right or benefit, or obligation or liability, granted or arising under
this Agreement, and any other dispute between the Executive and Asyst arising from or relating to
the Executives employment or termination of employment, shall be subject to and resolved
exclusively by binding non-appealable arbitration. The terms and conditions of the Agreement to
Arbitrate Disputes and Claims shall govern such arbitration (in the event entered between the
parties, and as amended from time to time), be binding on the Executive and Asyst and shall be
deemed incorporated herein by reference as a material part of this Agreement. Neither the
Executive nor Asyst shall be liable to, or entitled to recover from, the other, for any claim,
cause or action, suit or proceeding relating to any right or obligation hereunder, any incidental,
special, consequential or exemplary damages of any kind, including punitive damages (and the
arbitrator will be without jurisdiction to award such damages). The arbitrator also will 10

##### 



not have authority to award attorneys fees or costs to either party, unless a statute at
issue which is the basis for the dispute expressly authorizes the award of attorneys fees or costs
to the prevailing party. In this instance, the arbitrator shall have the authority to make an
award of only of reasonable attorneys fees and costs to the prevailing party, and to the extent
and in the manner permitted by the applicable statute. However, any award of fees and costs will
be limited to the amount of reasonable fees and costs actually incurred and which bear a reasonable
relation to the prevailing partys actual recovery. IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first
above written. ASYST TECHNOLOGIES, INC.By:
