SEPARATION AGREEMENT BETWEEN ROBERT MACKNIGHT
AND MATTSON TECHNOLOGY, INC.


November 14, 2007



Robert MacKnight

Re:Separation Agreement






Dear Bob:   

This letter, upon signature, will constitute agreement (the "Agreement") by you to the terms of your separation from Mattson
Technology, Inc. ("Mattson").  





	Transition:  On March 31, 2008 (the "Transition Date"), you will transition from President and Chief Operating Officer
to Vice President.  As of March 31, 2008, you no longer will have (nor may you represent yourself as having) the express or implied right or
authority to enter into any contracts, or incur any expenses, obligations or liabilities on behalf of or in the name of Mattson.


	Employment as Vice President:  The term of your employment as a Vice President shall be 16 months (through July 31, 2009)
(hereafter, the "Transition Period").  You will remain a Mattson employee during the Transition Period.  While you continue to
provide services to Mattson as an employee, Mattson will pay you the compensation and provide you the benefits described in Paragraph 3
of this Agreement.  During the Transition Period, Mattson will continue to provide you with an electronic mail account and office phone
number.


	Payments and Benefits:  In consideration for your promise to provide services under this Agreement, and your provision of
those services, as well as the other promises and representations made by you in this Agreement, Mattson will provide you with the following
payments and benefits: 



	Payments:  Mattson will pay to you your full current salary for a period of 8 months, beginning at the close of business on the
Transition Date and continuing through November 30, 2008.  Thereafter, Mattson will pay to you half of your current salary for a period of 8
months, beginning December 1, 2008 and continuing through July 31, 2009.  You understand and agree that Mattson will withhold taxes
from, and report, these amounts to tax authorities as Mattson determines it is required to do.  The salary payments described in this
paragraph will hereafter be referred to as the "Transition Payments."


	Benefits:  Immediately following the Transition Date, Mattson will provide to you the following employment benefits (the
"Transition Benefits"):



	Continuation of Existing Company-Paid Benefits:  During the Transition Period, Mattson will continue to provide to you all
company-paid benefits to which you are currently entitled.  Mattson reserves the right to modify in the future its company-paid benefit plans
(or the providers thereof).  Mattson agrees that, at the conclusion of the Transition Period, you will be entitled to seek continued health
benefits under the Consolidated Omnibus Budget Reconciliation Act (COBRA).  


	Continuation of Stock Vesting:  All stock options that you have been granted by Mattson on or before the Transition Date shall
continue to vest during the Transition Period.  The period for exercising these options shall be determined under the terms applicable to those
options.  For example, given a 90-day exercise period under the option terms, if you remain employed through July 31, 2009, you generally
would have until October 31, 2009 to exercise those options, to the extent vested. 


	Computer Stipend:  Mattson will pay you a stipend in an amount sufficient to purchase a personal computer that is equivalent in
capability to the Mattson-owned computer you currently use.


	Bonus:  If Mattson's Board of Directors approves the payment of bonuses relating to the first half of 2007 to any member of
Mattson's Executive Team (i.e. CEO and CFO), you will also be paid a bonus for the first half of 2007 in an amount to be determined by the
Board of Directors.


	Payment for Unused Sabbatical.  Mattson will pay you 7 weeks pay in lieu of the Sabbatical for which you are qualified to take,
but have not yet done so.  This payment will be in addition to any amounts due to you for accrued and unused Personal Time Off. 


	Releases:



	Release of Claims:  By signing this Agreement, you irrevocably and unconditionally release all Claims described in Paragraph
4(b) that you may now have against the Released Parties specified below.


	Claims Released:  In exchange for Mattson's promises under this Agreement, you hereby release (i.e., give up) all
known and unknown claims that you presently have against Mattson, its current or former subsidiaries and affiliates, and their current and
former Board members, partners, employees or agents, and any related parties (Released Parties), except claims that the law does not
permit you to waive by signing this Agreement.  For example, you are releasing all common law contract, tort, or other claims you might have,
as well as all claims you might have under the Age Discrimination in Employment Act (ADEA), the WARN Act, Title VII of the Civil Rights Act
of 1964, Sections 1981 and 1983 of the Civil Rights Act of 1866, the Americans With Disabilities Act (ADA), the Employee Retirement Income
Security Act of 1974 (ERISA), and similar state or local laws, such as the California Fair Employment and Housing Act, California Labor Code
Section 200 et seq., and any applicable California Industrial Welfare Commission order.  You expressly waive the protection of Section 1542
of the Civil Code of the State of California, which states that:

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of
executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.


	No Assignment of Claims:  By signing this Agreement, you expressly warrant that you have not assigned or given away any of
the Claims you are releasing.


	Representations and Promises:  You acknowledge and agree that:  



	Entire Agreement; Amendment.  This Agreement is the entire agreement relating to your service with Mattson and any claims or
future rights that you might have with respect to Mattson and the Released Parties.  This Agreement only may be amended by a written
agreement that Mattson and you sign.  This Agreement is a legally admissible, enforceable agreement governed by Federal law and the laws
of California.


	No Reliance on Representations.  When you decided to sign this Agreement, you were not relying on any representations that
were not in this Agreement.


	Future Changes to Employee Compensation.  You understand that Mattson in the future may change or improve employee
benefits or offer new programs to its employees. You further agree that you will not seek to receive any such additional pay, benefits or
programs.  


	No Wrongs, Injuries or Unpaid Amounts.  You acknowledge that you have not suffered any job-related wrongs or injuries, such
as any type of discrimination, for which you might be entitled to compensation or relief in the future.  You represent that you have been paid
all wages, commissions, compensation, benefits, and other amounts that Mattson or any Released Party should have paid you in the past.



	Severability.  If Mattson or you successfully assert that any provision in this Agreement is void, the rest of the Agreement shall
remain valid and enforceable unless the other party to this Agreement elects to cancel it.  If this Agreement is canceled, you will repay all
amounts paid to you pursuant to this Agreement.  


	Truth of Representations.  If you initially did not think any representation you are making in this Agreement was true or if you
initially was uncomfortable making it, you resolved all your doubts and concerns before signing this Agreement.  


	Voluntariness.  You have carefully read this Agreement, you fully understand what it means, you are entering into it knowingly
and voluntarily, and all your representations in it are true.  


	Consideration Period.  You understand that the consideration period described in the box above your signature started when
you first were given this Agreement, and you waive any right to have it restarted or extended by any subsequent changes to this Agreement.



	Representations and Promises as Consideration.  You understand that Mattson would not have given you the Transition
Payments or Benefits that you are getting in exchange for this Agreement but for the representations and the promises you are making by
signing it. 


	Disclosures and Cooperation.  You have disclosed to Mattson any information you have concerning any conduct involving
Mattson or any affiliate that you have any reason to believe may be unlawful or that involves any false claims to the United States.  You
further agree that, as requested by Mattson, you will cooperate fully with Mattson or its representatives in any investigation, proceeding,
administrative review or litigation pertaining to matters occurring during your employment with Mattson.  You understand that nothing in this
Agreement prevents you from cooperating with any U.S. government investigation.  In addition, to the fullest extent permitted by law,
you hereby irrevocably assign to the U.S. government any right you might have to any proceeds or awards in connection with any false
claims proceedings against Mattson or any affiliate.


	Company Property and Incurring of Liabilities.  On or before the Transition Date, you will return to Mattson all computers, files,
memoranda, documents, records, copies of the foregoing, Company-provided credit cards, keys, building passes, security passes, access or
identification cards, and any other property of Mattson or any Released Party in your possession or control.  By the Transition Date, you will
have cleared all expense accounts, repaid everything you owe to Mattson or any Released Party, paid all amounts you owe on
Company-provided credit cards or accounts (such as cell phone accounts), and canceled or personally assumed any such credit cards or accounts.
You further agree not to incur any expenses, obligations, or liabilities on behalf of Mattson from the date of this Agreement until the Transition
Date without written consent from Mattson's Chief Executive Officer. 


	Adverse Tax Treatment.  You agree not to make any claim against Mattson or any other person based on how Mattson reports,
or withholds taxes from, any amounts payable under this Agreement, or if an adverse determination is made as to the tax treatment of any
amounts payable under this Agreement.  You agree that Mattson has no duty to try to prevent such an adverse determination.


	Non-Disparagement.  You agree not to criticize, denigrate, or otherwise disparage Mattson, any other Released Party, or any of
Mattson's products, processes, experiments, policies, practices, standards of business conduct, or areas or techniques of research.  Mattson
agrees not to criticize, denigrate or otherwise disparage me.  


	Transitioning of Responsibilities.  You agree that you will fully cooperate with Mattson in effecting a smooth transition of your
responsibilities to others.


	Proprietary Information and Innovations Assignment Agreement.  I acknowledge agreement to the terms contained in the
Proprietary Information and Innovations Assignment Agreement signed by me on August 17, 2001, a copy of which is attached as Exhibit A.



	Deferred Compensation Plan.  Mattson agrees that it, through its officers, will present to its Board of Directors a request for
approval of an amendment to Mattson's existing Deferred Compensation Plan (the "Plan") that would allow qualified Mattson
employees whose age plus years of service equals 65 at the time their active services for Mattson terminate or are materially reduced to
defer Plan distributions in a manner that does not violate Internal Revenue Code Section 409A.  If this amendment is adopted, you will be
permitted to defer your Plan distributions if you satisfy the amendment's terms.   


	Arbitration of Disputes:  Mattson and you agree to resolve any future disputes through final and binding arbitration.  For
example, you are agreeing to arbitrate any dispute about the validity of this Agreement or any discrimination claim that may survive this
Agreement.  You also agree to resolve through final and binding arbitration any disputes you have with any other Released Party who elects
to arbitrate those disputes under this subsection.  Arbitrations shall be conducted by JAMS in accordance with its employment dispute
resolution rules.  This agreement to arbitrate does not apply to government agency proceedings.  By writing your initials in the following
blank, ____ , you are acknowledging that you understand this section's arbitration requirements and that arbitration would be in lieu of a jury
trial.


	Future References.  Any request for a reference about you by a prospective employer must be made to the Chief Executive Officer
or Vice President of Organizational Capability.  In response to such a request, Mattson agrees that it will respond to such request in a manner
to be mutually agreed by you and Mattson.


	Future Employment During the Transition Period.  Mattson agrees that you may obtain new employment during the Transition
Period, provided that: 

(i) such employment does not violate your promises under paragraph 6 of this Agreement, and (ii) such employment does not interfere with
your provision of services under this Agreement.  The parties intend that the services rendered by you under this Agreement shall be
part-time and shall not be so onerous as to prevent you from full-time services for a different employer.    


	Outplacement Services.  Mattson agrees that it will pay, at your request, for outplacement services acceptable to Mattson to
help you find new employment, provided that the new employment you seek would not violate your promises under Paragraph 6 of this
Agreement. 







	
YOU MAY NOT MAKE ANY CHANGES TO THE TERMS OF THIS AGREEMENT.  BEFORE SIGNING THIS
AGREEMENT, READ IT CAREFULLY AND, IF YOU CHOOSE, DISCUSS IT WITH YOUR ATTORNEY AT YOUR OWN EXPENSE.  TAKE
AS MUCH TIME AS YOU NEED TO CONSIDER THIS AGREEMENT BEFORE DECIDING WHETHER TO SIGN IT, UP TO 21 DAYS.  BY
SIGNING IT YOU WILL BE WAIVING YOUR KNOWN AND UNKNOWN CLAIMS.  


YOU MAY REVOKE THIS AGREEMENT IF YOU REGRET HAVING SIGNED IT.  TO DO SO, YOU MUST DELIVER A WRITTEN
NOTICE OF REVOCATION TO GENE TANGE AT 47131 Bayside Parkway, Fremont, California 94538 BEFORE SEVEN 24-HOUR

EXHIBIT A TO SEPARATION AGREEMENT BETWEEN ROBERT
MACKNIGHT AND MATTSON TECHNOLOGY,
INC.


PROPRIETARY INFORMATION AND

                  INNOVATIONS ASSIGNMENT AGREEMENT


This Agreement, effective as of August 20, 2001, confirms certain terms of my employment with Mattson Technology, Inc. (the
"Company"), and is a condition and a material part of the consideration for my employment by the Company and the
compensation that I receive from the Company from time to time.

1.Proprietary Information.


1.1As used in this Agreement, "proprietary information" means any information that was or will be developed, created, or
discovered by or on behalf of any natural person or entity (collectively, "person") or that became or will become known by, or was
or is conveyed to, any person, which has commercial value in the business of such person, including non-public information which I should
reasonably expect such person to regard as confidential, whether or not it is marked as "confidential".  By way of illustration, but
not limitation, proprietary information includes technical and non-technical information about software programs and subroutines, source and
object code, algorithms, mask works, trade secrets, designs, specifications, technology, know-how, processes, procedures, data, ideas,
techniques, inventions (whether or not patentable), works of authorship (whether or not protected or protectable as copyright), formulas,
manuals, business and product development plans and forecasts, client or customer lists, terms of compensation and performance levels of
any employee of such person, information relating to such person's customers and other information concerning actual or anticipated
business, research, development, experimental work, production, manufacturing and engineering processes, as well as prices and pricing
structures, marketing and sales information, product lines, other financial information, and any information, documents and materials relating
thereto, or which is or are received in confidence by or for such person from any other person.


1.2As used in this Agreement, "Mattson Proprietary Information" means any proprietary information that was or will be
developed, created, or discovered by or on behalf of the Company or its affiliates (collectively, "Mattson") or that became or will
become known by, or was or is conveyed to, any Mattson entity, which has commercial value in the business of the Company or any other
Mattson entity.


2.Ownership and Non-disclosure of Mattson Proprietary Information


2.1All Mattson Proprietary Information is and shall be the sole property of the Company, other Mattson companies, their assignees
or customers, as the case may be, and the Company, other Mattson companies, their assignees and customers accordingly, shall be the sole
owner of all patents, copyrights, mask works, trade secrets and other rights in connection therewith.  I hereby assign to the Company any
rights and interest I may have or acquire in Mattson Proprietary Information.


2.2.I agree that at all times, both during the term of my employment with the Company and after its termination for any reason
whatsoever, I shall hold in strictest confidence and trust and shall not, directly or indirectly, use or disclose to any person without the prior
written authorization of the Company, except as may be necessary in the ordinary course of performing my employment duties as an
employee of the Company, any Mattson Proprietary Information that I may have or acquire during the period of my employment with the
Company or anything directly or indirectly relating to Mattson Proprietary Information.


2.3Notwithstanding the foregoing, it is understood that at all times I am free to use information which is generally known in the trade
or industry not as a result of a breach of this Agreement, as well as my own skill, knowledge, know-how and experience not directly related to
my employment with the Company.


2.4I have been informed and acknowledge that misappropriation of the Company's trade secrets may result in
civil liability under the Uniform Trade Secrets Act, as adopted in California Civil Code Section 3426 or analogous provisions in other relevant
jurisdictions, and, if willful, may result in an award for triple the amount of the Company's damages and attorneys' fees; and that unauthorized
use of trade secrets may be a crime under California Penal Code Section 499(c), punishable by imprisonment for a time not exceeding one
(1) year, or by a fine not exceeding five thousand dollars ($5,000), or by both, or under analogous provisions in other relevant jurisdictions
..

3.Third Party Information


I recognize that the Company has received and will receive in the future proprietary information from third parties subject to a duty on
the Company's part to maintain the confidentiality of such information and/or to use it only for certain limited purposes.  I agree that I owe the
Company and such third parties, both during the term of my employment and thereafter, a duty to hold such proprietary information in the
strictest confidence and not to disclose it to any natural person or entity (except in a manner that is consistent with the Company's agreement
with the third party) or use it for the benefit of anyone other than the Company or such third party (consistent with the Company's agreement
with the third party), unless expressly authorized to act otherwise by an officer of the Company.  


4.Former Employer Information.


I agree that I shall not, during my employment with the Company, improperly use or disclose any proprietary information or trade secrets
of my former or concurrent employers (if any) or companies for which I performed or perform consulting services (if any) and that I shall not
bring onto the premises of the Company any unpublished documents or any property belonging to such employers or companies without their
written consent. 


5.Innovations.


5.1As used in this Agreement, the term " Innovations" means any and all new or useful art, discovery, improvement, technical
development, inventions, and works of authorship, whether or not patentable, protectable under applicable copyright laws or registrable, and
all related know-how, designs, mask works, trademarks, formulae, processes, manufacturing techniques, trade secrets, ideas, artwork,
software or other copyrightable or patentable works or proprietary information which I may solely or jointly acquire, conceive, develop or
reduce to practice.


5.2As used in this Agreement, the term "Mattson Innovations" means any and all Innovations which I may solely or jointly
acquire, conceive, develop or reduce to practice during the period of my employment with the Company.


6.Ownership of Prior Innovations


6.1I have attached hereto, as Exhibit A, a complete list of all Innovations that I have, alone or jointly with others,
conceived, developed or reduced to practice or caused to be conceived, developed or reduced to practice prior to the commencement of my
employment with the Company, that I consider to be my property or the property of third parties and that I wish to have excluded from the
scope of Mattson Proprietary Information.  If disclosure of an item on Exhibit A would cause me to violate any prior confidentiality
agreement, I understand that I am not to list such item in Exhibit A, but am to inform the Company that all items have not been listed
for that reason.  A space is provided on Exhibit A for such purpose.  If no list is attached, I represent that there are no such
items.


6.2To the extent I use any such prior Innovation in the course of my employment by the Company, I hereby grant the Company
a fully paid, royalty-free, worldwide, perpetual, irrevocable license (with rights to sublicense through multiple tiers of sublicensors) to make,
use, sell, reproduce, distribute, modify, perform and display such prior Innovation.


7.Ownership of Mattson Innovations


7.1I hereby acknowledge and agree that the Company shall acquire ownership, title, and all rights and interest in and to all Mattson
Innovations upon creation, that all Mattson Innovations are work made for hire belonging to the Company under applicable law, and that I
shall promptly disclose and describe to the Company all Mattson Innovations.  Without limiting the generality of the foregoing, I acknowledge
that all original works of authorship which are made by me (solely or jointly with others) within the scope of my employment and which are
protectable by copyright are "works made for hire," as that term is defined in the United States Copyright Act (17 U.S.C., Section 101).


7.2To the extent that under applicable mandatory laws the Company does not acquire ownership, title, and all rights and interests in
and to all Mattson Innovations, I hereby irrevocably and absolutely assign and agree to assign to the Company my entire ownership, right,
title, and interest in and to all Mattson Innovations and any associated intellectual property rights.  

7.3I hereby acknowledge and agree that my execution of this Agreement constitutes written notification to me, as required by
Section 2872 of the California Labor Code, of my rights under Section 2870 of the California Labor Code ("Section 2870").  Accordingly, I
recognize that this Agreement does not require assignment of any invention which qualifies fully for protection under Section 2870, which
provides as follows:


(a)Any provision in an employment agreement which provides that an employee shall assign, or offer to assign,
any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her
own time without using the employer's equipment, supplies, facilities, or trade secret information except for those inventions that
either:

(1)Relate at the time of conception or reduction to practice of the invention to the employer's business, or actual
or demonstrably anticipated research or development of the employer; or

(2)Result from any work performed by the employee for the employer.



(b)To the extent a provision in an employment agreement purports to require an employee to assign an invention
otherwise excluded from being required to be assigned under subdivision (a), the provision is against the public policy of this state and is
unenforceable.





7.4I hereby assign to the United States government all my right, title and interest in and to any and all Innovations whenever full title
to same is required to be in the United States by a contract between the Company and the United States or any of its agencies.

7.5To the fullest extent permitted by applicable law, I hereby irrevocably and unconditionally waive and undertake not to assert any
right to claim any  compensation in addition to my regular salary with respect to the use or exploitation of Mattson Innovations.

8.Moral Rights


To the fullest extent permitted by applicable law, any assignment hereunder (and any ownership of a Mattson Innovation as a work
made for hire) includes all rights of publication, attribution, paternity, integrity, disclosure and withdrawal and any other right that may be
known as or referred to as "moral right" (collectively "Moral Rights").  To the extent such Moral Rights cannot be
assigned under applicable law, I hereby irrevocably and unconditionally waive and undertake not to assert such Moral Rights and consent to
any action of the Company or other Mattson entity that would violate such Moral Rights in the absence of such consent.


9.Cooperation in Perfecting Rights to Mattson Innovations


9.1I shall assist the Company in every proper way to obtain and enforce United States and foreign proprietary rights relating to any
and all Mattson Innovations in any and all countries.  To that end I shall execute, verify and deliver such documents and perform such other
acts (including appearing as a witness) as the Company may reasonably request for use in applying for, obtaining, perfecting, evidencing,
sustaining and enforcing such proprietary rights and the assignment thereof.  In addition, I shall execute, verify and deliver assignments of
such proprietary rights to the Company or its designee.  I further agree to execute such powers of attorney conforming to all applicable
formalities, as may be necessary or appropriate, for the Company to do all such lawfully permitted acts to further the prosecution and
issuance of patents, copyrights, mask works or other rights relating to Mattson Innovations.  My obligation to assist the Company with respect
to proprietary rights in any and all countries shall continue beyond the termination of my employment, but the Company shall compensate me
at a reasonable rate after termination of my employment for the time actually spent by me at the Company's request on such assistance.


9.2In the event the Company is unable for any reason, after reasonable effort, to secure my signature on any document needed in
connection with the actions specified in the preceding paragraph, I hereby irrevocably designate and appoint the Company and its duly
authorized officers and agents as my agent and attorney-in-fact, to act for and in my behalf to execute, verify and file any such documents
and to do all other lawful acts to further the purposes of the preceding paragraph with the same legal force and effect as if executed by me.  I
hereby waive and quitclaim to the Company any and all claims of any nature whatsoever which I now or may hereafter have for infringement
of any proprietary rights assigned to the Company or its designee.


10.Obligation to Keep the Company Informed.


In addition to my obligations under Section 7 hereof, during the period of my employment and for one (1) year after termination of my
employment for any reason, I shall promptly disclose to the Company fully and in writing all patent applications filed by me or on my behalf.
At the time of each such disclosure, I shall advise the Company in writing of any inventions that I believe fully qualify for protection under
Section 2870 or analogous provisions in other relevant jurisdictions; and I shall at the time provide to the Company in writing all evidence
necessary to substantiate that belief.  I understand that the Company will keep in confidence and will not disclose to third parties without my
consent any proprietary information disclosed in writing to the Company pursuant to this Agreement relating to inventions that qualify fully for
protection under the provisions of Section 2870 or analogous provisions in other relevant jurisdictions.  I shall preserve the confidentiality of
any such invention as does not qualify fully for protection under Section 2870 or analogous provisions in other relevant jurisdictions.  I agree
to keep and maintain adequate and current records (in the form of notes, sketches, drawings and in any other form that may be required by
the Company) of all proprietary information developed by me and all inventions and other Innovations made by me during the period of my
employment at the Company, which records shall be available to and remain the sole property of the Company at all times.


11.No Conflicting Employment;  No Inducement of Other Employees or Solicitation of Customers.


11.1During the period of my employment by the Company, I shall not, without the Company's express written consent, engage in
any other employment or business activity directly related to the business in which the Company is now involved or becomes involved, nor
will I engage in any other activities which conflict with my obligations to the Company.


11.2For the period of my employment by the Company and for one (1) year after the date of termination of my employment by the
Company, in any county in the United States or equivalent geographical subdivision in foreign jurisdictions in which the Company does
business (a list of which is available from Human Resources and is incorporated herein), I shall not (i) induce or attempt to induce any
employee of the Company or another Mattson entity to leave the employ of the Company or such other Mattson entity; or (ii) actively solicit
the business of any client or customer of the Company or the client or customer of another Mattson entity (other than on behalf of the
Company or another Mattson entity), with whom I developed a relationship during the term of my employment, by using the Company's trade
secret or confidential information.


11.3If any restriction set forth in the preceding paragraphs of this Section 11 is found by any court of competent jurisdiction to be
unenforceable because it extends for too long a period of time or over too great a range of activities or in too broad a geographic area, it shall
be interpreted to extend only over the maximum period of time, range of activities or geographic area as to which it may be enforceable.


12.No Conflicting Obligations.


I represent that my performance of all terms of this Agreement and as an employee of the Company does not and shall not breach any
agreement to keep in confidence information acquired by me in confidence or in trust prior to my employment by the Company.  I have not
entered into, and I agree I shall not enter into, any agreement either written or oral in conflict herewith


13.Return of Company Documents.


When I leave the employ of the Company, I shall deliver to the Company (and shall not keep in my possession, recreate or deliver to
anyone else) any and all devices, records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints,
sketches, materials, equipment, other documents or property, together with all copies thereof (in whatever medium recorded) belonging to the
Company, its successors or assigns.  I further agree that any property situated on the Company's premises and owned by the Company,
including disks and other storage media, filing cabinets or other work areas, is subject to inspection by Company personnel at any time with
or without notice.  Prior to leaving, I shall, at the Company's request, cooperate with the Company in completing and signing the Company's
termination certification in substantially the form of Exhibit B attached hereto.


14.Notification of New Employer.


I hereby authorize the Company to notify my new employer of my rights and obligations under this Agreement following the termination of
my employment with the Company.


15.Legal and Equitable Remedies.


Because my services are personal and unique and because I may have access to and become acquainted with Mattson Proprietary
Information, the Company shall have the right to enforce this Agreement and any of its provisions by injunction, specific performance or other
equitable relief, without bond and without prejudice to any the rights and remedies that the Company may have for a breach of this
Agreement.






16.No Continuation of Employment.



I understand and acknowledge that my employment with the Company is "at-will," which means that the Company and I,
each, have the right to terminate my employment at any time, with or without advance notice and with or without cause.  I further agree and
understand that nothing in this Agreement shall confer on me any right with respect to continuation of employment by the Company, nor shall
it change in any way my "at-will" employment relationship with the Company.


17.Governing Law;  Consent to Personal Jurisdiction.


In view of the fact that the principal office of the Company is located in California, this Agreement shall be governed by and construed
according to the laws of the State of California, excluding conflict of laws principles.  I hereby expressly consent to the personal jurisdiction of
the state and federal courts located in _______________ County, California for any lawsuit filed there against me by the Company arising
from or relating to this Agreement.


18.Entire Agreement.


This Agreement, and Exhibit A attached hereto and incorporated herein by this reference, sets forth the final, complete and
exclusive agreement and understanding between the Company and me relating to the subject matter hereof and supersedes all prior and
contemporaneous understandings and agreements relating to its subject matter.  No modification of or amendment to this Agreement, nor
any waiver of any rights under this Agreement, shall be effective unless in writing and signed by both the Company and me.  Any subsequent
change or changes in my duties, salary or other compensation shall not affect the validity or scope of this Agreement.


19.Severability.


Should any provision of this Agreement be held by a competent court or other tribunal to be illegal, invalid or unenforceable, the legality,
validity and enforceability of the remaining provisions of this Agreement shall not be affected or impaired thereby.


20.Successors and Assigns.


This Agreement shall be binding upon my heirs, executors, administrators and other legal representatives and shall be for the benefit
of the Company, other Mattson entities, and its or their successors and assigns.


21.Survival.


The provisions of this Agreement shall survive the termination of my employment with the Company and the assignment of this
Agreement by the Company to any successor in interest or other assignee.
