 SUNPOWER CORPORATION 
 4.75% Senior Convertible Debentures due 2014 
  

	1.	Interest 

 SUNPOWER CORPORATION, a Delaware
corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Debenture at the rate per annum shown
above. The Company will pay interest semiannually on April 15 and October 15 of each year commencing on October 15, 2009. Interest on the Debentures will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the Issue Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If a payment date is not a Business Day, payment will be made on the next succeeding Business Day, and no additional
interest will accrue in respect of such payment by virtue of the payment being made on such later date. 
  

	2.	Method of Payment 

 The Company will pay interest on
the Debentures (except defaulted interest) to the Persons who are registered holders of Debentures at the close of business on the March 31 and September 30 next preceding the interest payment date even if Debentures are canceled after the
record date and on or before the interest payment date, except as otherwise provided in the Indenture. Holders must surrender Debentures to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the
United States of America that at the time of payment is legal tender for payment of public and private debts. The Company shall pay interest (i) on any Global Debentures by wire transfer of immediately available funds to the account of the
Depositary or its nominee, (ii) on any Debentures in certificated form having a principal amount of less than $2,000,000, by check mailed to the address of the Person entitled thereto as it appears in the Register, provided, however,
that at maturity interest will be payable at the office of the Company maintained by the Company for such purposes, which shall initially be an office or agency of the Trustee (as defined below) and (iii) on any Debentures in certificated form
having a principal amount of $2,000,000 or more, by check or otherwise by wire transfer in immediately available funds at the election of the Holder of such Debentures duly delivered to the Trustee at least five Business Days prior to the relevant
interest payment date, provided, however, that, at maturity, interest will be payable at the office of the Company maintained by the Company for such purposes, which shall initially be an office or agency of the Trustee. 
  

	3.	Paying Agent, Registrar, Service Agent and Conversion Agent 

 Initially, Wells Fargo Bank, National Association, a national banking association (the “Trustee”), will act as Paying Agent, Registrar, Service Agent and Conversion Agent. The Company may appoint and change any Paying Agent,
Registrar or co-registrar, Service Agent or Conversion Agent without notice. The Company or any of its domestically incorporated Subsidiaries may act as Paying Agent, Registrar or co-registrar, Service Agent or Conversion Agent. 
  

	4.	Indenture 

 The Company issued the Debentures under
an Indenture dated as of February 7, 2007 (the “Base Indenture”), as supplemented by the Third Supplemental Indenture dated as of May 4, 2009 (the “Third Supplemental Indenture” and together with the Base Indenture the
“Indenture”), between the Company and the Trustee. The terms of the Debentures include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
§§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Debentures are subject to all such terms,
and Debentureholders are referred to the Indenture and the TIA for a statement of those terms. 
 The Debentures are senior unsecured
obligations of the Company. This Debenture is one of the Debentures referred to in the Indenture issued in an aggregate principal amount of $230,000,000. The Indenture imposes limitations on the ability of the Company to consolidate or merge with or
into any other Person or convey, transfer or lease all or substantially all of the property of the Company.

	5.	Optional Redemption 

 The Debentures are not
redeemable at the option of the Company. 
  

	6.	Sinking Fund 

 The Debentures are not subject to any
sinking fund. 
  

	7.	Repurchase of Debentures at the Option of Debentureholders 

 If a Fundamental Change occurs at any time prior to maturity of the Debentures, this Debenture will be subject to a repurchase, at the option of the Holder, on a Fundamental Change Repurchase Date, specified by the Company, that is not less
than 20 calendar days nor more than 35 calendar days after notice thereof, at a repurchase price equal to 100% of the principal amount hereof, together with accrued and unpaid interest on this Debenture to, but excluding, the Fundamental Change
Repurchase Date; provided, however, that if such Fundamental Change Repurchase Date falls after a record date and on or prior the corresponding interest payment date, the accrued and unpaid interest shall be payable to the Holder of record of
this Debenture on the preceding April 15 or October 15, as the case may be. The Debentures submitted for repurchase must be $1,000 in principal amount or whole multiples thereof. The Company shall deliver to all holders of record of the
Debentures a notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the fifth calendar day after the occurrence of such Fundamental Change. For Debentures to be so repurchased at the
option of the Holder, the Holder must deliver to the Paying Agent in accordance with the terms of the Indenture, the Repurchase Notice containing the information specified by the Indenture, together with such Debentures, duly endorsed for transfer,
or (if the Debentures are Global Debentures) book-entry transfer of the Debentures, prior to 5:00 p.m., New York City time, on the Fundamental Change Repurchase Date. The repurchase price must be paid in cash. 
 Holders have the right to withdraw any Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal at any time prior to 5:00 p.m.,
New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date, as provided in the Indenture. 
 If
cash sufficient to pay the repurchase price of and accrued and unpaid interest, if any, on all Debentures or portions thereof to be repurchased as of the Fundamental Change Repurchase Date is deposited with the Paying Agent on the Business Day
immediately following the Fundamental Change Repurchase Date, then such Debentures will cease to be outstanding and interest will cease to accrue, and the Holder thereof shall have no other rights as such other than the right to receive the
repurchase price upon delivery or book-entry transfer of such Debentures. 
  

	8.	Conversion 

 In compliance with the provisions of
the Indenture, on or prior to the close of business on the Business Day immediately preceding the Maturity Date of this Debenture, the Holder hereof has the right, at its option, to convert each $1,000 principal amount of this Debenture into
Class A Common Stock based on a Conversion Rate of 37.8788 shares of Class A Common Stock per $1,000 principal amount of Debentures (a Conversion Price of approximately $26.40 per share), as the same may be adjusted pursuant to the terms
of the Indenture, as such shares shall be constituted at the date of conversion, upon surrender of this Debenture (if in certificated form) with the form entitled “Conversion Notice” on the reverse hereof duly completed and manually
signed, to the Company at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, or at the option of such Holder, the Corporate Trust Office, together with any funds required pursuant to the
terms of the Indenture, and, unless any shares issuable on conversion are to be issued in the same name as this Debenture, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder
or by such Holder’s duly authorized attorney. In order to exercise the 

  

 2 

 
conversion right with respect to any interest in a Global Debenture, the Holder must complete the appropriate instruction form pursuant to the
Depositary’s book-entry conversion program, deliver by book-entry delivery an interest in such Global Debenture, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the
funds, if any, required pursuant to the terms of the Indenture. As specified in the Indenture, upon conversion, the Company will issue shares of Class A Common Stock based on the Conversion Rate, as adjusted as specified in the Indenture.

 Prior to the Maturity Date, if and only to the extent holders elect to convert the Debentures in connection with a Non-Stock Change of
Control, the Company will increase the Conversion Rate applicable to such converting Debentures as set forth in the Indenture. 
 No
adjustment in respect of interest on any Debentures converted or dividends on any shares issued upon conversion of such Debentures will be made upon any conversion except as set forth in the next sentence. If this Debenture (or portion hereof) is
surrendered for conversion during the period from the 5:00 p.m., New York City time, on any applicable Record Date for the payment of interest to 5:00 p.m., New York City time, on the Business Day preceding the corresponding Interest Payment Date,
this Debenture (or portion hereof being converted) must be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the interest otherwise payable on such Interest Payment Date on the
principal amount being converted; provided, that no such payment shall be required (1) if the Holder surrenders this Debenture for conversion in connection with a Fundamental Change and the Company has specified a Fundamental Change
Repurchase Date that is after a Record Date and on or prior to the corresponding Interest Payment Date, (2) if the Holder surrenders this Debenture after the Record Date immediately preceding the Maturity Date or (3) to the extent of any
overdue interest, if overdue interest exists at the time of conversion with respect to this Debenture. 
 No fractional shares will be issued
upon any conversion of Debentures, but an adjustment and payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Debentures for conversion.

 A Debenture in respect of which a Holder is exercising its right to require repurchase may be converted only if such Holder validly
withdraws its election to exercise such right to require repurchase in accordance with the terms of the Indenture. 
  

	9.	Denominations, Transfer, Exchange 

 The Debentures
are in registered form without coupons in denominations of $1,000 and whole multiples of $1,000. A Debentureholder may transfer or exchange Debentures in accordance with the Indenture. Upon any transfer or exchange, the Registrar or the Company may
require a Debentureholder, among other things, to furnish appropriate endorsements or a written instrument or instruments of transfer in form satisfactory to the Company. Neither the Company, the Trustee nor the Registrar shall be required to
exchange, issue or register a transfer of (a) any Debentures or portions thereof surrendered for conversion pursuant to Article 8 of the Third Supplemental Indenture and (b) any Debentures or portions thereof tendered for repurchase (and
not withdrawn) pursuant to Section 3.04 of the Third Supplemental Indenture. 
  

	10.	Persons Deemed Owners 

 The registered Holder of
this Debenture may be treated as the owner of it for all purposes. 
  

	11.	Unclaimed Money 

 Subject to any applicable
abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest and any shares of Class A Common Stock or other property due in respect of
converted Debentures that remains unclaimed for two years, and, thereafter, Debentureholders entitled to the money and/or securities must look to the Company for payment as general creditors. 
  

 3 

	12.	Amendment, Waiver 

 Subject to certain exceptions
set forth in the Indenture, (i) the Indenture or the Debentures may be amended without prior notice to any Holder but with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding Debentures and
(ii) any default or noncompliance with any provision may be waived with the written consent or affirmative vote of the holders of at least a majority in principal amount of the outstanding Debentures. Without the consent of any Holder, the
Company and the Trustee may amend the Indenture or the Debentures (i) to cure any ambiguity, defect or inconsistency, provided, however, that such modification or amendment does not adversely affect the interests of the Holders in
any material respect, provided, further, that any amendment made solely to conform the provisions of the Indenture or the Debentures to the description of the Debentures contained in the Prospectus Supplement shall not be deemed to
adversely affect the interests of the Holders; (ii) to comply with Article 5 of the Third Supplemental Indenture; (iii) to provide for uncertificated Debentures in addition to or in place of certificated Debentures; (iv) to make any
change that does not adversely affect the rights of any Holder; (v) to evidence and provide for the acceptance of appointment by a successor Trustee with respect to the Debentures; (vi) to comply with requirements of the SEC in order to
effect or maintain the qualification of the Indenture under the TIA; (vii) to provide for conversion rights of Holders and the Company’s repurchase obligations in connection with a Fundamental Change in the event of any reclassification of
the Class A Common Stock, merger or consolidation, or sale, conveyance, transfer or lease of the Company’s property and assets substantially as an entirety; (viii) to secure the Debentures; (ix) to surrender any right or power
conferred upon the Company in the Indenture; (x) to add to the covenants of the Company for the benefit of the Holders; (xi) to make any provision with respect to matters or questions arising under the Base Indenture, the Third
Supplemental Indenture or the Debentures that the Company may deem necessary or desirable and that shall not be inconsistent with the Base Indenture or the Third Supplemental Indenture or the Debentures, provided, however, that such
change or modification does not, in the good faith opinion of the Board of Directors, adversely affect the interests of the Holders in any material respect; (xii) to increase the Conversion Rate; and (xii) to add guarantees of the
obligations under the Debentures. 
  

	13.	Defaults and Remedies 

 If an Event of Default
occurs (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company) and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then-outstanding
Debentures, by written notice to the Company and the Trustee, may declare due and payable 100% of the principal amount of all outstanding Debentures plus any accrued and unpaid interest to the date of payment. If an Event of Default relating to
certain events of bankruptcy, insolvency or reorganization of the Company occurs, all unpaid principal and accrued and unpaid interest on the outstanding Debentures shall become due and immediately payable without any declaration or other act on the
part of the Trustee or any Holder. Under certain circumstances, the Holders of a majority in aggregate principal amount of the outstanding Debentures may rescind and annul any such acceleration with respect to the Debentures and its consequences.

 If an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Subject to certain exceptions, no Holder may pursue any remedy with
respect to the Indenture or the Debentures unless (i) such Holder has previously given the Trustee notice that an Event of Default is continuing, (ii) holders of at least 25% in principal amount of the outstanding Debentures have requested
the Trustee in writing to pursue the remedy, (iii) such Holders have offered the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense, (iv) the Trustee has not complied with such
request within 60 days after the receipt of the request and the offer of indemnity and (v) the holders of a majority in principal amount of the outstanding Debentures have not given the Trustee a direction inconsistent with such request within
such 60-day period. Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Debentures are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. Subject to the Indenture, the Trustee, however, may refuse to follow any direction if the Trustee, in good faith shall, by a Trust Officer of the Trustee, determine that the
proceeding so directed would involve the Trustee in personal liability. The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request, order or direction of any Holder pursuant to the
provision of the Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred therein or thereby. 
  

 4 

 No reference herein to the Indenture and no provision of this Debenture or of the Indenture shall impair,
as among the Company and the Holder of the Debentures, the obligation of the Company, which is absolute and unconditional, to pay the principal of, and interest or make-whole premium, if any, in respect of the Debenture at the place, at the
respective times, at the rate and in the coin or currency herein and in the Indenture prescribed. 
  

	14.	Trustee Dealings with the Company 

 Subject to
certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Debentures and may otherwise deal with and collect obligations owed to it by the Company or its
Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	15.	No Recourse Against Others 

 A director, officer,
employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Debentures or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each
Debentureholder by accepting a Debenture waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Debentures. 
  

	16.	Authentication 

 This Debenture shall not be valid
until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Debenture. 
  

	17.	Abbreviations 

 Customary abbreviations may be used
in the name of a Debentureholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform
Gift to Minors Act). 
  

	18.	GOVERNING LAW 

 THIS DEBENTURE SHALL BE DEEMED TO BE
A CONTRACT UNDER THE LAWS OF THE STATE OF NEW YORK, AND FOR ALL PURPOSES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF SUCH STATE INCLUDING, WITHOUT LIMITATION, SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW. 

 

	19.	CUSIP and ISIN Numbers 

 Pursuant to a
recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Debentures and has directed the Trustee to use CUSIP and ISIN numbers in notices of
redemption as a convenience to Debentureholders. No representation is made as to the accuracy of such numbers either as printed on the Debentures or as contained in any notice of redemption and reliance may be placed only on the other identification
numbers placed thereon. 
 The Company will furnish to any Holder upon written request and without charge to the Holder a copy of the
Indenture which has in it the text of this Debenture.

the event that any of the above vesting dates falls on a day that the Company is not open for business, then vesting of the applicable portion shall occur on the next succeeding day that the Company is open for business. 
  

	1.4.	Expiration of Option. To the extent that the Option shall not have been exercised, this Option shall expire at 5:00 p.m. local time at the Company’s headquarters
on February 19, 2016 and no part of the Option may be exercised thereafter. If an expiration, termination or forfeiture date described herein falls on a weekday, Employee must exercise Employee’s Option before 5:00 p.m. local time
at the Company’s headquarters on that date. If an expiration, termination or forfeiture date described herein falls on a weekend or any other day on which the NASDAQ stock market is not open, Employee must exercise the Options before 5:00 p.m.
local time at the Company’s headquarters on the last NASDAQ business day prior to the expiration, termination or forfeiture date. 

  

	1.5.	 Exercise of Option. When and as vested, this Option may be exercised up to the number of shares of Stock specified in Section 1.1 above only by
serving written notice on the designated stock plan administrator. Payment of the Option exercise price specified in Section 1.2 above may be made by: (a) payment in cash; (b) arrangement with the Company’s stock
plan administrator which is acceptable to the Company where payment of the Option exercise price is made pursuant to an irrevocable direction to the broker to deliver all or part of the proceeds from the sale of the shares of the Stock issuable
under the Option to the Company; (c) exchange of previously owned shares of Stock, valued at fair market value on the day of exercise as provided in the Plan; (d) delivery of 

	 	 
any other lawful consideration approved in advance by the Administrator specified in the Plan or its delegate, or (e) any combination of the
foregoing. Fractional shares may not be exercised. Employee will have the rights of a stockholder only after the shares of Stock have been issued to Employee in accordance with this Agreement. 

  

	1.6.	No Assignment of Option. This Option may not be assigned or transferred except as may otherwise be provided by the terms of this Agreement. 

 

	1.7.	Basic Adjustments for Changes in Capital Structure. The Administrator shall make adjustments from time to time in the number of shares of Stock covered by the Option
as specified in Section 1.1 above in such reasonable manner as the Administrator may determine to reflect any increase or decrease in the number of issued shares of Stock of the Company resulting from a subdivision or consolidation of shares or
any other capital adjustment, the payment of stock dividends or other increases or decreases in such Stock effected without receipt of consideration by the Company. 

  

	1.8.	Termination of Employment with the Company. All exercisable Options granted herein must be exercised within ninety (90) days following the date on which the
employment of Employee with the Company or one of its subsidiaries terminates (i.e., last day worked, excluding any severance period) (“Termination Date”), or be forfeited, except as provided in Section 2.3 below and as follows:

  

	 	(a)	In the event of Employee’s death during employment, each Option granted hereunder will be exercisable, whether or not vested on the date of Employee’s death, until
the earlier of: (1) the first anniversary of Employee’s date of death; or (2) the original expiration date of the option. In the event of Employee’s death during a Special Exercise Period as specified in
Section 2.3 below, each Option will continue to be exercisable in accordance with the provisions of that Section. 

  

	 	(b)	In the event of the termination of employment of Employee due to Disablement, Employee may exercise the Option, to the extent not previously exercised and whether or not the
option had vested on or prior to the date of employment termination, at any time prior to 365 days following the later of the date of Employee’s termination of employment due to Employee’s Disablement or the date of determination of
Employee’s Disablement, provided, however, that while the claim of Disablement is pending, Options that were unvested at termination of employment may not be exercised and Options that were vested at termination of
employment may be exercised only during the period set forth in the introductory clause to this Section 1.8. The Option shall terminate on the 365th day from the date of determination of Disablement, to the extent that it is unexercised. For
these purposes “Disablement” shall be determined in accordance with the standards and procedures of the then-current Long Term Disability policies maintained by the Company, which is generally a physical condition arising from an illness
or injury, which renders an individual incapable of performing work in any occupation, as determined by the Company. 

  

	 	(c)	If Employee’s employment is terminated for “Cause”, all granted but unexercised stock Options shall be forfeited on Employee’s Termination Date.

  

	1.9.	Suspension of Option Exercises. For administrative or other reasons, the Company may, from time to time, suspend the ability of employees to exercise options for
limited periods of time. Notwithstanding the above, the Company shall not be obligated to deliver any shares of Stock during any period when the Company determines that the exerciseability of the Option or the delivery of shares hereunder would
violate any federal, state or other applicable laws. 

  

 -2- 

	1.10.	Withholding of Income Taxes. Nonqualified stock options are taxable upon exercise. To the extent required by applicable federal, state or other law, Employee shall
make arrangements satisfactory to the Company for the satisfaction of any withholding tax obligations that arise by reason of an Option exercise and, if applicable, any sale of shares of the Stock. The Company shall not be required to issue shares
of the Stock or to recognize any purported transfer of shares of the Stock until such obligations are satisfied. The Administrator designated in the Plan may permit these obligations to be satisfied by having the Company withhold a portion of the
shares of the Stock that otherwise would be issued to Employee upon exercise of the Option, or to the extent permitted by the Administrator, by tendering shares of the Stock previously acquired. 

 ARTICLE II—GENERAL PROVISIONS 
  

	2.1.	Definitions. Except as otherwise expressly provided, all terms used herein shall have the same meaning as in the Plan. The term “Administrator” means the
Management Development & Compensation Committee of the Company’s Board of Directors. 

  

	2.2.	Mergers, etc. In the event of any of (i) a consolidation or merger in which the Company is not the surviving corporation or which results in the
acquisition of all or substantially all of the Company’s then outstanding common stock by a single person or entity or by a group of persons and/or entities acting in concert, (ii) a sale or transfer of all or substantially all the
Company’s assets, or (iii) a dissolution or liquidation of the Company (a “Covered Transaction”), the vesting of all Options under each outstanding Award pursuant to Article I above will be accelerated and such shares will
become fully exercisable prior to the Covered Transaction on a basis that gives the undersigned a reasonable opportunity, as determined by the Administrator, following delivery of the shares, to participate as a stockholder in the Covered
Transaction. In connection with any Covered Transaction in which there is an acquiring or surviving entity, the Administrator may provide for substitute or replacement Awards from, or the assumption of Awards by, the acquiring or surviving entity or
its affiliates, any such substitution, replacement or assumption to be on such terms as the Administrator determines, provided that no such replacement or substitution shall diminish in any way the acceleration of Options provided for in this
section. 

  

	2.3.	Retirement, etc. If Employee ceases to be an employee due to retirement with the consent of the Administrator, Employee will be entitled to a special exercise period
with respect to the Option (the “Special Exercise Period”) which will begin on Employee’s Retirement Date and will end on the earlier of the 3rd anniversary of Employee’s Retirement Date or February 19, 2016. During the
Special Exercise Period, the Option will continue to vest in accordance with the schedule specified in Section 1.3 above and will be exercisable to the same extent that it would have been exercisable had Employee remained employed by the
Company or one of its subsidiaries. As used herein the term “retirement with the consent of the Administrator” means that Employee’s retirement must be with the consent of the Administrator, which consent may be granted or withheld in
the discretion of the Administrator. In the event that Employee ceases to be an employee under circumstances that would otherwise qualify for retirement but the consent of the Administrator has not been granted, then Employee shall not be entitled
to the benefits of this Section 2.3. 

  

	2.4.	No Understandings as to Employment. The undersigned Employee further expressly acknowledges that nothing in the Plan or any modification thereto, in the Award or in
this Agreement shall constitute or be evidence of any understanding, express or implied, on the part of the Company to employ the Employee for any period or with respect to the terms of the undersigned’s employment or to give rise to any right
to remain in the service of the Company or of any subsidiary or affiliate of the Company, and the undersigned shall remain subject to discharge to the same extent as if the Plan had never been adopted or the Award had never been made.

  

 -3- 

	2.5.	Acts of Misconduct. If Employee has allegedly committed an act of serious misconduct, including, but not limited to, embezzlement, fraud, dishonesty, unauthorized
disclosure of trade secrets or confidential information, breach of fiduciary duty or nonpayment of an obligation owed to the Company, an Executive Officer of the Company may suspend Employee’s rights under the Award, including the vesting of
Restricted Stock and Options and the exercise of vested Options, pending a decision by the Administrator or an Executive Officer to terminate the Award. No rights under the Award may be exercised during such suspension or after such termination.

  

	2.6.	Disputes. The Administrator designated in the Plan or its delegate shall finally and conclusively determine any disagreement concerning the Award.

  

	2.7.	Savings Clause. In the event that Employee is employed in a jurisdiction where the performance of any term or provision of this Agreement by the Company:
(i) will result in a breach or violation of any statute, law, ordinance, regulation, rule, judgment, decree, order or statement of public policy of any court or governmental agency, board, bureau, body, department or authority, or
(ii) will result in the creation or imposition of any penalty, charge, restriction, or material adverse effect upon the Company, then any such term or provision shall be null, void and of no effect. 

  

	2.8.	Amendment. This Agreement may be amended only by an instrument in writing executed and delivered by the Employee and the Company.
