Exhibit 10.9  

 
 

SECOND AMENDED AND RESTATED    
    
    GT SOLAR INTERNATIONAL, INC.    
    
    2006 STOCK OPTION PLAN    
    

        This Second Amended and Restated GT Solar International, Inc. 2006 Stock Option Plan, dated as of January 15, 2008, amends that certain Amended and
Restated 2006 Stock Option Plan, dated as of July 7, 2006 (the "First Amended Plan"), of GT Solar Incorporated (f/k/a GT Equipment
Technologies, Inc.) ("GT Solar"). 

        WHEREAS,
the 2006 Stock Option Plan was originally adopted by GT Equipment Technologies, Inc. on December 30, 2005, (the "Original
Plan"), and the First Amended Plan amended and restated the Original Plan; 

        WHEREAS,
pursuant to the Agreement and Plan of Merger, dated September 28, 2006, by and among GT Solar, GT Solar Merger Corp. and GT Solar International, Inc. (the
"Company"), (i) GT Solar became a wholly-owned subsidiary of the Company, (ii) each share of common stock of GT Solar, par value $0.01
("GT Solar Stock"), was exchanged for one share of common stock of the Company, par value $0.01 ("Company
Stock"), and (iii) each option to purchase shares of GT Solar Stock was converted into an option to purchase an equivalent number of shares of Company Stock; 

        WHEREAS,
the board of directors and the sole stockholder of the Company deem it to be in the best interests of the Company to amend and restate the First Amended Plan to reflect the fact
that each previously issued option to purchase shares of GT Solar Stock was converted to an option to purchase
an equivalent number of shares of Company Stock; and to provide for the future issuance of stock options to acquire shares of Company Stock, in order to provide an incentive to selected employees,
officers, directors, consultants and advisors of the Company and of the Company's subsidiaries and affiliates; and 

        NOW,
THEREFORE, the First Amended Plan, including the form of stock option agreement attached as Exhibit A thereto, is hereby amended and restated as follows: 

1.    Purpose.    

        The
purpose of the GT Solar International, Inc. 2006 Stock Option Plan (the "Plan") is to provide an incentive to selected
employees, officers, directors, consultants and advisors of the Company and of the Company's subsidiaries and affiliates (the Company and its subsidiaries and affiliates are referred to collectively
as the "Group" and individually as a "Group Company") by granting such persons either
non-qualified options ("Non-qualified Stock Options") or incentive stock options ("Incentive Stock
Options"), or a combination of both, to acquire shares ("Shares") of the Company's common stock, par value $0.01 per share
(Non-qualified Stock Options and Incentive Stock Options are individually and collectively referred to as "Options"). Any person granted an
option hereunder is referred to as an "Optionee." 

        It
is the Company's intent that Non-qualified Stock Options granted under the Plan not be classified as Incentive Stock Options, and that Incentive Stock Options be
consistent with and contain or be deemed to contain all provisions required under Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), or any successor thereto. If an Incentive Stock Option granted under the Plan does not qualify as such for any reason, then to the extent of
such non-qualification, the stock option represented thereby shall be regarded as a Non-qualified Stock Option duly granted under the Plan, provided that such stock option
otherwise meets the Plan's requirements for Non-qualified Stock Options. 

1

 

2.    Effective Date and Term of the Plan.    

        The
Plan is effective as of December 30, 2005 (the "Effective Date"). Subject to Section 10 and 11 below, the Plan shall
continue in effect from the Effective Date until the day before the tenth anniversary of the Effective Date (the "Termination Date"), provided that the
terms of the Plan shall continue in effect after the Termination Date for so long as is necessary to the enforcement of the rights and obligations of the Company and of any Optionee under the Plan or
any Option. In no event shall any
Options be granted under the Plan after the Termination Date. Options granted prior to the Termination Date shall remain in effect until the exercise, surrender, cancellation or expiration in
accordance with their terms and the terms of the Plan. 

3.    Stock Subject to the Plan.    

        (a)   Subject
to adjustment as provided in Section 10 below, the aggregate number of Shares subject to Options granted under the Plan shall not exceed 630,000 (the
"Total Authorized Shares"). 

        (b)   Shares
subject to Options that for any reason expire, or are canceled, terminated, forfeited or otherwise settled without the issuance of such Shares shall again be
available for award under the Plan, subject to the limitation set forth in Subsection (a) above. 

        (c)   Shares
issued upon exercise of Options may consist, in whole or in part, of Shares held in treasury or authorized but unissued Shares not reserved for any other purpose. 

        (d)   Shares
issued upon the exercise of Options shall be fully paid and nonassessable. 

        (e)   Unless
otherwise determined by the Company's Board of Directors (the "Board") or a committee thereof (the Board or such
committee is hereinafter referred to as the "Committee"), no Option shall be exercisable with respect to any fractional Shares. 

4.    Administration of the Plan.    

        (a)    Committee.    The Plan shall be administered by the Committee. The Committee shall at
all times consist of at least two members. Each member of the Committee shall be a director who is a "non-employee director" within the meaning of Rule 16(b)-3
promulgated by the Securities Exchange Commission under the Securities and Exchange Act of 1934, as amended, and, if necessary for any Options to qualify for any tax or other material benefit to
Optionees under applicable regulations under Section 162(m) of the Code, each shall be an "outside director" (as defined in applicable regulations). The Committee shall be appointed by, and
serve at the pleasure of, the Board. 

        (b)    Authority.    Subject to the specific limitations and restrictions set forth in the
Plan, the Committee shall have the authority: (i) to grant Options to such employees, officers, directors, consultants and advisors of a Group Company as the Committee shall select, provided
that the Committee may grant Incentive Stock Options only to eligible employees of the Company or its subsidiaries (as defined for this purpose in Section 424(f) of the Code or any successor
thereto); (ii) to make all determinations necessary or desirable for the administration of the Plan including, within any applicable limits specifically set out in the Plan, the number of
Shares that may be subject to Options, the Option Price, and the period during which an Optionee must remain an employee, officer, director, consultant or advisor of a Group Company prior to the
exercise of an Option; (iii) to construe the terms of the Option Agreement (as defined below) and the Plan; (iv) to prescribe, amend and rescind rules and regulations relating to the
Plan; (v) to determine the terms and provisions of the Option Agreements, which need to be the same, (vi) to correct any defect, supply any omission or reconcile any inconsistency in the
Plan or in any Option Agreement in any manner that the Committee deems necessary or desirable; (vii) to amend the terms of any Option, subject to the provisions of the Plan; (viii) to
grant to Optionees in exchange for their surrender of Options, new Options containing such other terms and conditions as the Committee 

2

 

shall
determine; and (ix) to make other determinations in the judgment of the Committee necessary or appropriate for the administration of the Plan. Any interpretation or decision of the
committee shall be final and conclusive. Nothing in this Section 4(b) shall give the committee the right to increase the Total Authorized Shares (except as provided in Section 10 below),
or to extend the term of the Plan. 

        (c)    Special Authority to Modify Plan and Option Terms.    Without limiting the foregoing or
any other power of authority of the committee, if the Committee at any time determines that the Plan or Options granted under the Plan are or may be subject to, and fail or may fail to comply with,
the requirements of Section 409A of the Code, the Committee may make such modifications to the Plan and to the terms of any awards under the Plan, including without limitations modifications
with respect to the exercisability of Options, as it deems advisable either to ensure that the Plan and Options granted under the Plan comply with any applicable requirements of Section 409A of
the Code. 

        (d)    Liability/Protection.    No member of the Committee shall be liable to any person for
any action taken or omitted in connection with the interpretation or administration of the Plan. Service as a member of the Committee shall constitute service as a member of the Board, so that members
of the Committee shall be entitled to indemnification for their service on the Committee to the full extent provided for service as members of the Board. 

5.    Option Grants.    

        (a)    Option Agreement.    The Committee shall, subject to the terms of the Plan, have sole
authority to determine the employees, officers, directors, consultants and advisors to whom Options shall be granted under the Plan and the terms and conditions of such Options. Each Option granted
under the Plan shall be evidenced by a stock option agreement (each, an "Option Agreement"). Each Option Agreement shall be subject to the terms and
conditions of the Plan and may contain additional terms
and conditions (which may vary from Optionee to Optionee) not inconsistent with the Plan, as the committee may deem necessary or desirable. Unless the Committee determines otherwise at the time of any
grant, each Option Agreement for employees or officers shall be in substantially the form attached hereto as Exhibit A, with adjustments as
reasonably necessary for non-employee directors, consultants or advisors. 

        (b)    Option Price.    The price at which a Share may be purchased upon exercise of an Option
(the "Option Price") shall be determined by the Committee at the time the Option is granted, and shall be specified in the applicable Option Agreement.
Unless the Committee sets a higher price at the time an Option is granted, the Option Price shall be the Fair Market Value of a Share on the date the Option is granted (the
"Grant Date"), and in the case of the grant of any Incentive Stock Option to an Optionee who, at the time of the grant, owns more than 10% of the total
combined voting power of all classes of stock of the Company or any Group Company, the Option Price may not be less than 110% of the Fair Market Value of a Share as of the date of grant of the
Incentive Stock Option, in each case unless otherwise permitted by Section 409A and Section 422 of the Code or any successor thereto. "Fair Market
Value" means, as of any date, the fair market value of a Share as determined in good faith by the Committee, with reference to any factors the Committee considers appropriate,
such determination by the Committee to be final, conclusive and binding. The Option Price shall be subject to adjustment in accordance with Section 10 hereof and shall be paid in cash or cash
equivalent or in such other form of payment as the Committee in its discretion may allow, to the extent consistent with any applicable requirements of the Code. 

        (c)    Number of Shares.    Each Option Agreement shall specify the number of Shares subject
thereto. 

3

 

        (d)    Option Term.    The Committee shall determine the term of each Option (the
"Option Term"); provided that no Option Term shall extend for a period continuing beyond ten (10) years from the Grant Date; provided further
that in the case of the grant of any Incentive Stock Option to an Optionee who at the time of the grant owns more than 10% of the total combined voting power of all classes of stock of the Company or
any Group Company, the Option Term may not extend for a period continuing beyond five (5) years from the Grant Date. 

        (e)    Limit on Incentive Stock Options.    If required by the Code, the aggregate Fair Market
Value (determined as of the grant date) of Shares for which an Incentive Stock Option is exercisable for the first time during any calendar year under all equity incentive plans of the Group Companies
(as defined in Section 422 of the Code or any successor thereto) may not exceed $100,000. 

6.    Exercise of Options.    

        Subject
to applicable law and the terms and conditions of the Plan, an Option granted under the Plan shall be exercisable at such time, or times, upon the occurrence of such event or
events, for such period or periods, in such amount or amounts, and upon the satisfaction of such terms and conditions, including, without limitations, terms and conditions relating to notice of
exercise, the date the Option is deemed exercised, delivery and transferability of Shares and withholding taxes, as the Committee shall specify in the Option Agreement. 

7.    Expiration of Options.    

        Any
unexercised Option shall automatically and without notice expire upon the first to occur of the following: 

        (a)   the
tenth anniversary of the Grant Date, or such earlier date as may be specified in the applicable Option Agreement; or 

        (b)   upon
termination of the Optionee's service as an employee, officer, director, consultant or advisor with a Group Company, except to the extent otherwise specified in the
applicable Option Agreement or as determined by the Committee. 

        Notwithstanding
the foregoing, no Incentive Stock Option granted to an Optionee who at the time of the grant owns more than 10% of the total combined voting power of all classes of stock
of the Company or any Group Company shall be exercisable more than five (5) years from the Grant Date. 

8.    Non-Transferability of Options.    

        (a)   Except
as otherwise provided in any applicable Option Agreement, no Option granted under the Plan shall be transferable by any Optionee other than by will or the laws of
descent or distribution. Except as otherwise provided in any applicable Option Agreement, during the lifetime of an Optionee, an Option shall be exercisable only by the Optionee. Except as otherwise
determined by the Committee, any attempt to transfer, assign, pledge, hypothecate, or otherwise dispose of, or to subject to execution, attachment or similar process, any Option other than as
permitted above or in the applicable Option Agreement shall be null and void and of no effect, and shall result in termination of the Option and forfeiture of all rights with respect thereto. 

        (b)   The
Company may require that any Optionee, as a condition to exercise of any Option, give written assurances in substance and form satisfactory to the Company to the
effect that he or she is acquiring the Shares subject to the Option for his or her own account for investment and not with any present
intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with applicable Federal and state securities laws. 

4

 

        (c)   Notwithstanding
anything to the contrary in the Plan or in any Option Agreement, no Option may be exercised and no Shares or certificates representing Shares shall be
issued if, in the judgment of the Committee, such exercise or issuance would constitute a violation of any state or Federal law or the rules or regulations of any governmental regulatory body or any
securities exchange. If, at any time, counsel to the Company determines that the Shares must be listed, registered or otherwise qualified on any securities exchange or under any state or Federal law,
or that the consent or approval of any governmental or regulatory body is necessary as a condition of, or in connection with the issuance or purchase of Shares pursuant to any Option, the Option may
not be exercised, in whole or in part, unless and until all required listings, registrations, qualifications, consents and approvals have been effected or obtained on conditions acceptable to the
Board. Nothing herein shall be deemed to require the Company to apply for or to obtain any such listing, registration, qualification, consent or approval. 

9.    No Special Rights.    

        No
Optionee shall have any voting or other rights as a stockholder of the Company with respect to any Shares covered by an Option until exercise of the Option and issuance of a
certificate or certificates to the Optionee for such Shares. Nothing herein or in any Option Agreement shall confer on any Optionee any right to continued employment or service for a Group Company or
interfere in any way with the rights of a Group Company to terminate such employment or service at any time. 

10.    Adjustment for Change in Capital Structure and Special Transactions.    

        (a)    Recapitalization, etc.    In the event of a stock dividend, stock split or
recapitalization or a corporate reorganization in which the Company is a surviving corporation, including without limitation a merger, consolidation, split-up or spin-off or a
liquidation or distribution of securities or assets other than cash dividends (a "Restructuring Event"), the number or kinds of Shares subject to the
Plan or to any Option previously granted, and the Option Price, shall be adjusted by the Committee as it reasonably determines in consistent with the purposes of the Plan to reflect such Restructuring
Event. 

        (b)    Special Transactions.    In the event of (x) a merger, consolidation or other
form of reorganization of the Company or GT Solar Holdings, LLC ("Holdings"), as applicable, with or into another corporation or other entity, (y) a sale or transfer of all or
substantially all of the assets of the Company or Holdings, as
applicable, or (z) a tender or exchange offer made by any corporation, person or entity, other than an offer made by the Company or Holdings, as applicable (a "Special
Transaction"), the Committee, either before or after the Special Transaction, may take such action as it reasonably determines is consistent with the purposes of the Plan with
respect to the number or kinds of Shares subject to the Plan or any Option under the Plan. Such action by the Committee may include (but shall not be limited to) the following: 

          (i)  accelerating
the full exercisability of an Option during such period as the Committee shall prescribe following the public announcement of such Special Transaction; 

         (ii)  canceling
the portion of any Option that has not become exercisable and is not scheduled to become exercisable prior to the date of the Special Transaction; 

        (iii)  permitting
any Optionee, at his or her election and within any time period as the Committee may prescribe, to surrender Options (or any portion thereof) in exchange
for cash payment in the amount and in a manner determined by the Committee; provided such an election by any Optionee shall not constitute an exercise of such surrendered Options, and such Optionee
shall not acquire any stockholder rights with respect to such surrendered Options; or 

5

 

        (iv)  requiring
any Optionee, at any time prescribed by the Committee, to surrender Options (or any portion thereof) (A) in exchange for cash payment as described in
clause (iii) above, provided in such case, that cash payment shall be in an amount per option equal to the difference between the Option Price and the Fair Market Value as of the date of
surrender or such other amount as the committee may determine, or (B) in exchange for and, if necessary, subject to shareholder approval, of a substitute Option or other award issued by the
corporation surviving such Special Transaction or acquiring the Company's assets, which the Committee, in the good faith exercise of its business judgment, determines to have a value substantially
equivalent to the value of the Options surrendered. 

11.    Amendment, Suspension or Termination of the Plan.    

        The
Committee may, at any time, amend, suspend or terminate the Plan or any part thereof, including without limitation, any and all parts of any Option granted under the Plan, in such
manner as the Committee deems necessary or desirable; provided that no such action may be taken which would impair the rights of any Optionee with respect to any Option previously granted under the
Plan without the Optionee's consent. 

12.    Stockholders Agreement.    

        Unless
otherwise determined by the Committee, on or before the date any Optionee will exercise any Option under the Plan, he or she shall become a party to the Employee Stockholders
Agreement, as amended from time to time, a copy of which is attached hereto as Exhibit B (as amended, the "Stockholders
Agreement"), which Stockholders Agreement provides, among other things, for certain restrictions on the transfer of Shares acquired pursuant to any Option granted under the
Plan ("Option Shares"). 

13.    Governing Law.    

        The
Plan shall be governed by the laws of the State of Delaware without regard to its conflict of laws principles. In case any one or more of the provisions contained herein are for any
reason deemed to be invalid, illegal or unenforceable in any respect by a judicial body having jurisdiction, such illegality, invalidity or unenforceability shall not effect any other provision of
this Plan, and this Plan shall be construed as if such invalid, unenforceable or illegal provision had never been contained herein. 

14.    References.    

        References
in the Plan to Optionee shall be deemed, where appropriate, to refer to the beneficiary or legal representative of any Optionee who dies or is determined to be physically or
mentally incompetent.

Exhibit 10.12    
    

GT SOLAR EQUIPMENT TECHNOLOGIES, INC. EMPLOYEE,

NON-COMPETITION, NON-DISCLOSURE, PROPRIETARY INFORMATION

AND PATENT AND INVENTION ASSIGNMENT AGREEMENT  

        In consideration of my employment or continued employment, as the case may be, with GT Solar Equipment Technologies, Inc. (the "Company"), and the
compensation received by me from the Company, from time to time, I hereby agree with the Company as follows: 

	1.
	Proprietary Information and Inventions—I understand and acknowledge that:

	A.
	The
Company is engaged in a continuous program of research, design, development, production, marketing and servicing with respect to its business and that as part of my employment by
the Company, I am (or may be), expected to make new contributions and inventions of value to the Company.

	B.
	My
employment creates a relationship of confidence and trust between me and the Company with respect to certain information applicable to the business of the Company or applicable to
the business of any client or customer of the Company, which may be made known to me by the Company or by any client or customer of the Company, or learned by me during the period of my employment.

	C.
	The
Company possesses, and will continue to possess, information that has been created, discovered or developed by, or otherwise become known to, the Company (including, without
limitation, information created, discovered, developed or made known by me during the period of or arising out of my employment by the Company, whether before or after the date hereof) or in which
property rights have been or may be assigned or otherwise conveyed to the Company, which information has commercial value in the business in which the Company is engaged and is treated by the Company
as confidential. All such information is hereinafter called "Proprietary Information", which term, as used herein, shall also include, but shall not be limited to, systems, processes, formulae, data,
functional specifications, computer programs, blueprints, know-how, improvements, discoveries, developments, designs, inventions, techniques, marketing plans, strategies, forecasts, new
products, unpublished financial statements, budgets, projections, licenses, prices, costs and customer and supplier lists; provided, however, that the term "Proprietary Information" shall not include
any of the foregoing which is in the public domain. -

	D.
	All
existing lists of customers of the Company, and all lists of customers of the Company developed during the course of my employment by the Company, are and shall be the sole and
exclusive property of the Company, and that I neither have nor shall have any right, title or interest therein; such lists of customers are and must continue to be confidential; and the Company's
present and future business relationship with its customers is and will continue to be of a type which normally continues unless interfered with by others.

	E.
	As
used herein, the period of my employment includes any time during which I may be retained by the Company as an Independent Contractor.

	2.
	Ownership of Proprietary Information—All Proprietary Information shall be the sole property of the
Company and its assigns, and the Company and its assigns shall be the sole owner of all patents, copyrights, trademarks and other rights in connection therewith. I hereby assign to the Company any
rights I may have or acquire in such Proprietary Information. I hereby acknowledge that all Proprietary Information is and must continue to be confidential and that the same is not readily accessible
to competitors of the Company. At all times, both during my employment by the Company and after its termination, I will keep in strictest confidence and trust all Proprietary Information and I will
not use or disclose any Proprietary Information without the written consent of the Company, except as may be necessary in the ordinary course of performing my duties as an employee of the Company. 

	3.
	Commitment to Company; Other Employment—During the period of my employment by the Company, I will
devote substantially all of my time for the Company and I will not, without the Company's prior written consent, engage in any employment or business other than for the Company.

	4.
	Documentation—In the event of the termination of my employment for any reason, I will deliver to the
Company all documents, notes, drawings, blueprints, formulae, specifications, computer programs, data and other materials of any nature pertaining to any Proprietary Information or to my work with the
Company, and will not take any of the foregoing or any reproduction of any of the foregoing that is embodied in a tangible medium of expression.

	5.
	Disclosure of Inventions—I will promptly disclose to the Company (or any persons designated by it)
all discoveries, developments, designs, improvements, inventions, blueprints, formulae, processes, techniques, computer programs, strategies, know-how and data, whether or not patentable
or registerable under copyright or similar statutes, made or conceived or reduced to practice or learned by me, either alone or jointly with others, during the period of my employment that are related
to the business of the Company, result from tasks assigned to me by the Company or result from the use of premises or property (including computer systems and engineering facilities) owned, leased or
contracted for by the Company (all such discoveries, developments, designs, improvements, inventions, formulae, processes, techniques, computer programs, strategies, blueprints, know-how
and data are hereinafter referred to as "Inventions"). I will also promptly disclose to the Company, and the Company hereby agrees to receive all such disclosures in confidence, all other discoveries,
developments, designs, improvements, inventions, formulae, processes, techniques, computer programs, strategies, blueprints, know-how and data, whether or not patentable or registerable
under copyright or similar statutes, made or conceived or reduced to practice or learned by me, either alone or jointly with others, during the period of my employment for the purpose of determining
whether they constitute "Inventions", as defined above.

	6.
	Ownership of Inventions—All Inventions shall be the sole property of the Company and its assigns,
and the Company and its assigns shall be the sole owner of all patents, copyrights, trademarks and other rights in connection therewith. I hereby assign to the Company any rights I may have or acquire
in such Inventions. I shall assist the Company in every proper way as to all such Inventions (but at the Company's expense) to obtain and, from time to time, enforce patents, copyrights, trademarks
and other rights and protections relating to said Inventions in any and all countries, and to that end, I will execute all documents for use in applying for and obtaining such patents, copyrights,
trademarks and other rights and protections on and enforcing such Inventions, as the Company may desire, together with any assignments thereof to the Company or persons designated by it. My obligation
to assist the Company in obtaining and enforcing patents, copyrights, trademarks and other rights and protections relating to such Inventions in any and all countries shall continue beyond the
termination of my employment, but the Company shall compensate me at a reasonable rate after my termination for time actually spent by me at the Company's request on such assistance. In the event the
Company is unable, after reasonable effort, to secure my signature on any document or documents needed to apply for or prosecute any patent, copyright or other right or protection relating to an
Invention, for any reason whatsoever, 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 on my behalf to execute and file any such application or applications and to do all other lawfully permitted acts to further the prosecution and issuance of patents, copyrights or similar
protections thereon with the same legal force and effect as if executed by me and I hereby ratify, affirm and approve all such lawfully permitted acts accordingly.

	7.
	Other Agreements—I represent and warrant that my execution and delivery of this Agreement and the
performance of all the terms of this Agreement does not and will not breach any agreement to keep in confidence proprietary information acquired by me in confidence or trust. I have not entered into
and shall not enter into any agreement, either written or oral, in conflict herewith. 

	8.
	Use of Confidential Information of Other Persons—I represent that I have not brought and will not
bring with me to the Company or use at the Company any materials or documents of an employer or a former employer that are not generally available to the public, unless express written authorization
from such employer for their possession and use has been obtained. I also understand that I am not to breach any obligation of confidentiality that I have to any employer or former employer and agree
to fulfill all such obligations during the period of my affiliation with the Company.

	9.
	Restrictive Covenant—I hereby acknowledge and recognize my possession of Proprietary Information and
the highly competitive nature of the business of the Company and accordingly agree that, in consideration of the premises contained herein, I will not, during the period of my employment by the
Company and in the event that my employment with the Company is terminated for any reason whatsoever and whether such termination be voluntary or involuntary, for a period of five years
(5) years following such termination, (i) directly or indirectly engage in any competitive business (defined as a business that designs, develops, manufactures, markets or sells a
product, product line or service that competes with any product, product line or service of the Company as they presently exist or as may be in existence or development on the date of termination of
my employment with the Company; a competitive business, includes, without limitation, a business that designs, develops, manufacturers, markets or sells any product, product line or service that uses
super critical substances either for cleaning, deposition, and/or sacrificial material removal within the semiconductor device manufacturing industry or for cleaning and drying in the microelectronics
device manufacturing industry), whether such engagement shall be as an employer, officer, director, owner, employee, partner or other participant, (ii) assist others in engaging in any
competitive business in the manner described in the foregoing clause (i), or (iii) induce employees of the Company, its affiliates or subsidiaries to terminate their employment with the
Company or such affiliate or subsidiary and/or engage in any competitive business. I understand that this Section 9 is not meant to prevent me from earning a living or fostering my career. It
does intend, however, to prevent any competitive business from gaining any unfair advantage from my knowledge of Proprietary Information. I understand that by making my new employer aware of the
provisions of this Section 9, they can take such action as to avoid my breaching the provisions hereof and to indemnify me in the even of a breach.

	10.
	Agreement Not to Solicit Customers—During the course of my employment by the Company for a period
of three (3) years following the termination of such employment for any reason whatsoever and whether such termination be voluntary or involuntary, I will not, directly or indirectly, as owner,
officer, director, stockholder, partner, associate, consultant, manager, advisor, representative, employee, agent, creditor or otherwise, attempt to solicit or in any other way disturb or service any
person, firm or corporation that has been a customer account of the Company at any time or times within three (3) years prior to the termination date of my employment, whether or not I had
direct account responsibility for a contact with such customer account.

	11.
	Remedies—I acknowledge that a remedy at law for any breach or threatened breach of the provisions
of this Agreement would be inadequate and, therefore, agree that the Company shall be entitled to injunctive relief in addition to any other available rights and remedies in case of any such breach or
threatened breach; provided, however, that nothing contained herein shall be construed as prohibiting the Company from pursuing any other remedies available for any such breach or threatened breach.

	12.
	Assignment—This Agreement and the rights and obligations of the parties hereto shall bind and inure
to the benefit of any successor or successors of the Company, whether by reorganization, merger, consolidation, sale of assets or otherwise, except that neither this Agreement nor any rights or
benefits hereunder may be assigned by me.

	13.
	Interpretation—It is the desire and intent of the parties hereto that the provisions of this
Agreement shall be enforced to the fullest extent permissible under the laws and public policies 

applied
in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated to be invalid or unenforceable, such provision shall be
deemed amended to delete there from the portion thus adjudicated to be invalid or unenforceable, such deletion to apply only with respect to the operation of such provision in the particular
jurisdiction in which such adjudication is made. In addition, if any one or more of the provisions contained in this Agreement shall, for any reason, be held to be excessively broad as to duration,
geographical scope, activity or subject, it shall be construed by limiting and reducing it so as to be enforceable to the extent compatible with the applicable law as it shall then appear. 

	14.
	Notices—Any notice which a party is required or may desire to give pursuant to this Agreement shall
be given by personal delivery or registered or certified mail, return receipt requested, addressed to the Employee at the address of the Employee of record with the Company and addressed to the
Company at its principal office, or at such other place as either party may, from time to time, designate in writing. The date of personal delivery or the date of mailing any such entice shall be
deemed to be the date of delivery thereof.

	15.
	Waivers—If either party shall waive any breach of any provision of this Agreement, her or it shall
not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement.

	16.
	Headings—The headings of the sections hereof are inserted for convenience only and shall not be
deemed to constitute a part hereof nor to affect the meaning hereof.

	17.
	Governing Law—This Agreement shall be governed by and construed and enforced in accordance with the
laws of the State of New Hampshire with respect to contracts made and to be performed wholly therein.

	18.
	No Employment Agreement—I acknowledge that this Agreement does not constitute an employment
agreement and agree that this Agreement shall be binding upon me regardless of whether or not my employment shall continue for any length of time hereafter and whether or not my employment is
terminated for any reason whatsoever by either the Company or me or both.

	19.
	Complete Agreement; Amendments: Prior Agreements—The foregoing is the entire agreement of the
parties with respect to the subject matter hereof and may not be amended, supplemented, canceled or discharged except by written instrument executed by both parties hereto. This Agreement supersedes
any and all prior agreements between the parties hereto with respect to the matters covered hereby.
