 The per share “Exercise Price” is intended to be at least equal to the fair market
value of the Company’s Common Stock at the date of grant. The Company has attempted in good faith to make the fair market value determination in compliance with applicable tax law although there can be no certainty that the U.S. Internal
Revenue Service (the “IRS”) will agree. If the IRS does not agree and asserts the fair market value at the time of grant is higher than the Exercise Price, the IRS could seek to impose greater taxes on you, including interest and penalties
under Internal Revenue Code Section 409A. While we think this is an unlikely event, we cannot provide absolute assurance and you may want to consult your own tax adviser with any questions.

 BRIGHTSOURCE ENERGY, INC. 

2006 STOCK PLAN 
 STOCK OPTION AGREEMENT 
 1. Grant of Option.
BrightSource Energy, Inc., a Delaware corporation (the “Company”), hereby grants to «Optionee» (“Optionee”), an option (the “Option”) to purchase the total number of shares of Common
Stock (the “Shares”) set forth in the Notice of Stock Option Grant (the “Notice”), at the exercise price per Share set forth in the Notice (the “Exercise Price”) subject to the terms, definitions
and provisions of the BrightSource Energy, Inc. 2006 Stock Plan (the “Plan”) adopted by the Company, which is incorporated in this Agreement by reference. Unless otherwise defined in this Agreement, the terms used in this Agreement
shall have the meanings defined in the Plan. 
 2. Designation of Option. This Option is intended to be an
Incentive Stock Option as defined in Section 422 of the Code only to the extent so designated in the Notice, and to the extent it is not so designated or to the extent the Option does not qualify as an Incentive Stock Option under Applicable
Law, then it is intended to be and will be treated as a Nonstatutory Stock Option. 
 Notwithstanding the above, if designated
as an Incentive Stock Option, in the event that the Shares subject to this Option (and all other Incentive Stock Options granted to Optionee by the Company or any Parent or Subsidiary, including under other plans of the Company) that first become
exercisable in any calendar year have an aggregate fair market value (determined for each Share as of the date of grant of the option covering such Share) in excess of $100,000, the Shares in excess of $100,000 shall be treated as subject to a
Nonstatutory Stock Option, in accordance with Section 5(c) of the Plan. 
 3. Exercise of Option. This Option
shall be exercisable during its term in accordance with the Vesting/Exercise Schedule set out in the Notice and with the provisions of Section 9 of the Plan as follows: 

(a) Right to Exercise. 

(i) This Option may not be exercised for a fraction of a share. 

(ii) In the event of Optionee’s death, disability or other termination of employment, the exercisability of the
Option is governed by Section 5 below, subject to the limitations contained in this Section 3. 
 (iii)
In no event may this Option be exercised after the Expiration Date of the Option as set forth in the Notice. 

  
 -1-

 (b) Method of Exercise. 

(i) This Option shall be exercisable by execution and delivery of the Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit B (the “Exercise Agreement”) or of any other form of written notice approved for such purpose by the Company which shall state Optionee’s election to exercise the Option, the number
of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company pursuant to the provisions of the
Plan. Such written notice shall be signed by Optionee and shall be delivered to the Company by such means as are determined by the Plan Administrator in its discretion to constitute adequate delivery. The written notice shall be accompanied by
payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price. 
 (ii) As a condition to the exercise of this Option and as further set forth in Section 11 of the Plan, Optionee agrees to make adequate provision for U.S. federal, state or other tax withholding
obligations, if any, which arise upon the vesting or exercise of the Option, or disposition of Shares, whether by withholding, direct payment to the Company, or otherwise. 

(iii) The Company is not obligated, and will have no liability for failure, to issue or deliver any Shares upon exercise
of the Option unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. This Option may not be exercised until such time as the Plan has been
approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable U.S. federal or state securities or other law
or regulation, including any rule under Part 221 of Title 12 of the U.S. Code of Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company may require Optionee to make any
representation and warranty to the Company as may be required by the Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on the date on which the Option is exercised with respect
to such Shares. 
 4. Method of Payment. Payment of the Exercise Price shall be by any of the following, or a
combination of the following, at the election of Optionee: 
 (a) cash or check; 

(b) cancellation of indebtedness; 
 (c) by surrender of other shares (meaning, shares not subject to this Option) of Common Stock of the Company that have an aggregate Fair Market Value on the date of surrender equal to the Exercise Price
of the Shares as to which the Option is being exercised. In the case of shares acquired directly or indirectly from the Company, such shares must have been owned by Optionee for more than six (6) months on the date of surrender (or such other
period of time as is necessary to avoid the Company’s incurring adverse accounting charges); or 

  
 -2-

 (d) following the date, if any, upon which the Common Stock is a Listed
Security, and if the Company is at such time permitting “same day sale” cashless brokered exercises, delivery of a properly executed exercise notice together with irrevocable instructions to a broker participating in such cashless brokered
exercise program to deliver promptly to the Company the amount required to pay the exercise price (and applicable withholding taxes). 
 5. Termination of Relationship; Early Termination of Option. Following the date of termination of Optionee’s Continuous Service Status for any reason (the “Termination
Date”), Optionee may exercise the Option only as set forth in the Notice and this Section 5. To the extent that Optionee is not entitled to exercise this Option as of the Termination Date, or if Optionee does not exercise this Option
within the Termination Period set forth in the Notice or the termination periods set forth below, the Option shall terminate in its entirety. In no event, may any Option be exercised after the Expiration Date of the Option as set forth in the
Notice. 
 (a) Termination. In the event of termination of Optionee’s Continuous Service
Status other than as a result of Optionee’s disability or death or for Cause (as defined in the Plan), Optionee may, to the extent Optionee is vested in the Option Shares at the Termination Date, exercise this Option during the Termination
Period set forth in the Notice. 
 (b) Other Terminations of Relationship. In connection with any
termination other than a termination covered by Section 5(a), Optionee may exercise the Option only as described below: 
 (i) Termination upon Disability of Optionee. In the event of termination of Optionee’s Continuous Service Status as a result of Optionee’s disability, Optionee may, but only within
twelve months from the Termination Date, exercise this Option to the extent Optionee was vested in the Option Shares as of such Termination Date. 
 (ii) Death of Optionee. In the event of the death of Optionee (a) during the term of this Option and while an Employee or Consultant of the Company and having been in Continuous Service
Status since the date of grant of the Option, or (b) within thirty (30) days after Optionee’s Termination Date, the Option may be exercised at any time within twelve months following the date of death by Optionee’s estate or by a
person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent Optionee was vested in the Option as of the Termination Date. 

(iii) Termination for Cause. In the event Optionee’s Continuous Service Status is terminated for Cause,
the Option shall terminate immediately upon such termination for Cause as set forth in Section 9(b)(iv) of the Plan. In the event Optionee’s employment or consulting relationship with the Company is suspended pending investigation of
whether such relationship shall be terminated for Cause, all Optionee’s rights under the Option, including the right to exercise the Option, shall be suspended during the investigation period, also as set forth in Section 9(b)(iv) of the
Plan. 

  
 -3-

 (c) Termination of Option. This Option may terminate prior to
its Expiration Date and prior to the dates specified under Section 5(a) and (b) above under certain circumstances as set forth in Section 13 of the Plan. 
 6. Non-Transferability of Option. Except as otherwise set forth in the Notice, this Option may not be transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by him or her. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and assigns of Optionee. 

7. Tax Consequences. The Company has not provided any tax advice with respect to this Option or the disposition of
the Shares. Optionee should obtain advice from an appropriate independent professional adviser with respect to the taxation implications of the grant, exercise, assignment, release, cancellation or any other disposal of this Option and on any
subsequent sale or disposition of the Shares. The per share Exercise Price of the Option is intended to be at least equal to the fair market value of the Company’s Common Stock at the date of grant. The Company has attempted in good faith to
make the fair market value determination in compliance with applicable tax law although there can be no certainty that the IRS will agree. If the IRS does not agree and asserts the fair market value at the time of grant is higher than the Exercise
Price, the IRS could seek to impose greater taxes on Optionee, including interest and penalties under Internal Revenue Code Section 409A. While the Company thinks this is an unlikely event, the Company cannot provide absolute assurance and
Optionee may want to consult Optionee’s own tax adviser with any questions. 
 8. Data
Protection. 
 (a) To facilitate the administration of the Plan and this Agreement, it will be
necessary for the Company (or its payroll administrators) to collect, hold and process certain personal information about Optionee and to transfer this data to certain third parties such as brokers with whom Optionee may elect to deposit any share
capital under the Plan. Optionee consents to the Company (or its payroll administrators) collecting, holding and processing Optionee’s personal data and transferring this data to the Company or any other third parties insofar as is reasonably
necessary to implement, administer and manage the Plan. 
 (b) Optionee understands that Optionee may, at any
time, view Optionee’s personal data, require any necessary corrections to it or withdraw the consents herein in writing by contacting the Company, but acknowledges that without the use of such data it may not be practicable for the Company to
administer Optionee’s involvement in the Plan in a timely fashion or at all and this may be detrimental to Optionee. 
 9.
Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Optionee hereby
agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the registration) without the prior written
consent of the Company or such underwriters, as the case may be, for 

  
 -4-

 
such period of time (not to exceed 180 days but subject to such extension or extensions as may be required by the underwriters in order to publish research reports while complying with Rule 2711
of the National Association of Securities Dealers, Inc.) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the
underwriters at the time of the public offering. 
 10. Governing Law. This Agreement and all acts and
transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law. 

11. Effect of Agreement. Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with
the terms and provisions thereof (and has had an opportunity to consult counsel regarding the Option terms), and hereby accepts this Option and agrees to be bound by its contractual terms as set forth herein and in the Plan. Optionee hereby agrees
to accept as binding, conclusive and final all decisions and interpretations of the Plan Administrator regarding any questions relating to the Option. In the event of a conflict between the terms and provisions of the Plan and the terms and
provisions of the Notice and this Agreement, the Plan terms and provisions shall prevail. The Option, including the Plan, constitutes the entire agreement between Optionee and the Company on the subject matter hereof and supersedes all proposals,
written or oral, and all other communications between the parties relating to such subject matter. 
 12. Investment
Representation. If Optionee satisfies one or more of the conditions set forth in paragraph (i) of Exhibit A, Optionee hereby represents that he is an “accredited investor” within the meaning of Regulation D of the U.S.
Securities Act of 1933 and agrees to promptly complete and execute the Investment Representations agreement attached hereto as Exhibit A. 

  
 -5-

 13. Restrictive Legends. The certificate or certificates representing the
Shares issued upon the exercise of the Option shall bear the following legends (as well as any legends required by applicable U.S. state and federal corporate and securities laws): 

 

	 	(a)	THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO,

	 	(b)	THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS (SUBJECT TO CERTAIN EXTENSIONS) AFTER THE EFFECTIVE DATE OF THE

 2006 STOCK PLAN 

EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 

This Agreement (“Agreement”) is made as of
                        , by and between BrightSource Energy, Inc., a Delaware corporation (the
“Company”), and «Optionee» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the Company’s 2006 Stock Plan
(the “Plan”). 
 1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser
hereby elects to exercise his or her option to purchase                              shares of the
Common Stock (the “Shares”) of the Company under and pursuant to the Plan and the Stock Option Agreement granted «GrantDate» (the “Option Agreement”). The purchase price for the Shares shall be
$«ExercisePrice» per Share for a total purchase price of $            . The term “Shares” refers to the purchased Shares and all securities received in
replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities or other
properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of
Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution and delivery of this Agreement in accordance with the provisions of Section 3(b) of
the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be purchased by Purchaser (which shall be issued in Purchaser’s name) against payment of the exercise price therefor by Purchaser
by any method listed in Section 4 of the Option Agreement. 
 3. Limitations on Transfer. In addition to any
other limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the Shares except in compliance with the provisions below and applicable securities laws. 

(a) Private Company. Purchaser acknowledges that the Company shall have the right, but not the obligation,
during the 30 days after the termination of Purchaser’s Continuous Service Status for any reason or after exercise of the Option if the Option is exercised after termination of Purchaser’s Continuous Service Status for any reason, to
repurchase the Shares. The repurchase price shall be the Fair Market Value of those Shares as of the date of the Termination. The Fair Market Value per Share will be determined as set forth in Section 3(c)(ii) of this Agreement. The repurchase
price shall be paid in cash. 
 (b) Right of First Refusal. Before any Shares held by Purchaser or
any transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or 

  
 -1-

 
otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set
forth in this Section 3(b) (the “Right of First Refusal”). 
 (i) Notice of Proposed
Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each
proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder
shall offer the Shares at the same price (the “Offered Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 

(ii) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the
Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price
determined in accordance with subsection (iii) below. 
 (iii) Purchase Price. The purchase
price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 3(b) shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of
the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (iv)
Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30
days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (v)
Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 3(b), then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 60 days after the date of the Notice and provided further that
any such sale or other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to apply to the Shares in the hands of such
Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new
Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

(vi) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 3(b)
notwithstanding, the transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate 

  
 -2-

 
Family or a trust for the benefit of Purchaser’s Immediate Family shall be exempt from the provisions of this Section 3(b). “Immediate Family” as used herein shall mean
spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further
transfer of such Shares except in accordance with the terms of this Section 3. 
 (c) Involuntary
Transfer. 
 (i) Company’s Right to Purchase upon Involuntary Transfer. In the event,
at any time after the date of this Agreement, of any transfer by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above) of all or a
portion of the Shares by the record holder thereof, the Company shall have an option to purchase all of the Shares transferred at the Fair Market Value of the Shares on the date of transfer. Upon such a transfer, the person acquiring the Shares
shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by the person acquiring
the Shares. 
 (ii) Price for Involuntary Transfer. With respect to any stock to be transferred
pursuant to Sections 3(a) or 3(c)(i), the Fair Market Value per Share shall be a price set by the Board of Directors of the Company in good faith using a reasonable valuation method in a reasonable manner in accordance with Section 409A of
the Code. The Company shall notify Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not
agree with the valuation as determined by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees
shall be borne equally by the Company and the Purchaser. 
 (d) Assignment. The right of the
Company to purchase any part of the Shares may be assigned in whole or in part to any stockholder or stockholders of the Company or other persons or organizations. 

(e) Restrictions Binding on Transferees. All transferees of Shares or any interest therein will receive and
hold such Shares or interest subject to the provisions of this Agreement. Any sale or transfer of the Company’s Shares shall be void unless the provisions of this Agreement are satisfied. 

(f) Termination of Rights. The right of repurchase granted by the Company in Section 3(a) above, the
right of first refusal granted the Company by Section 3(b) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(c) above shall terminate upon the first sale of Common Stock
of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon
termination of the rights to repurchase and the right of first refusal 

  
 -3-

 
described in Sections 3(a), 3(b) and 3(c) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in
Section 5(a)(ii) herein and delivered to Purchaser. 
 4. Investment and Taxation Representations. If
Purchaser satisfies one or more of the conditions set forth in Section 4(a) below in connection with the purchase of the Shares (an “Accredited Purchaser”), then Purchaser shall check the applicable box(es) in Section 4(a) and
Purchaser makes the representations to the Company set forth in Sections 4(a) through 4(k). If Purchaser does not satisfy one or more of the conditions set forth in Section 4(a) below in connection with the purchase of the Shares or does not
check one or more of the boxes set forth in Section 4(a) (a “Non-Accredited Purchaser”), then Purchaser makes only the representations set forth in Sections 4(e) through 4(k). 

(a) By checking one or more of the boxes as follows, that Purchaser is an “accredited investor” as defined in
Regulation D promulgated under the Securities Act: 
  

	 	 ̈	a. A natural person with an individual net worth, or joint net worth with a spouse, in excess of $1,000,000 (excluding the value of the primary residence of such
individual). 

  

	 	 ̈	b. A natural person (i) who has had an individual income in excess of $200,000 in each of the past two years or a joint income with a spouse in excess of $300,000
in those two years and (ii) who reasonably expects to reach the same income level in the current year. 

  

	 	 ̈	c. A director or executive officer of the Company. 

 (b) Purchaser possesses such knowledge and experience in finance, securities, investments and other business matters as to be able to protect Purchaser’s interests in connection with the potential
investment in the Company, and this potential investment is not material when compared to Purchaser’s total financial capacity. Purchaser has adequate means for providing for Purchaser’s current needs and possible contingencies, has no
need for liquidity regarding this potential investment, and has no reason to expect a change in Purchaser’s circumstances, financial or other, that may cause or require sale of this potential investment. 

(c) Purchaser understands the many risks of an investment in the Company and can afford to bear such risks, including, but
not limited to, the risk of losing Purchaser’s entire investment. 
 (d) Purchaser is acquiring the
securities to be offered under the Option for Purchaser’s own account for investment and not with a view to the sale or distribution thereof or the granting of any participation therein, and Purchaser has no present intention of distributing or
selling to others any of such securities or granting any participation therein. Purchaser has no agreement or other arrangement, formal or informal, with any person to sell, transfer, pledge or otherwise dispose of any of such securities that would
guarantee to Purchaser any profit, or 

  
 -4-

 
protect Purchaser against loss, regarding such securities, and Purchaser has no plans to enter into any such agreement or arrangement. 

(e) Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient
information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for resale in connection with,
any “distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity. 

(f) Purchaser understands that the Shares have not been registered under the Securities Act by reason of a specific
exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
 (g) Purchaser further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is
available. Purchaser further acknowledges and understands that the Company is under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the
transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company. 
 (h) Purchaser is familiar with the provisions of Rule 144 (and, in the case of a Non-Accredited Purchaser, Rule 701) promulgated under the Securities Act, which, in substance, permit limited public
resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser understands
that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 (or, in the case of a Non-Accredited Purchaser, Rule 701), which require, among other things, that the Company be
subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified time periods, and under certain
circumstances, that resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (h), Purchaser acknowledges and agrees to the restrictions set forth in paragraph (i) below.

 (i) Purchaser further understands that in the event all of the applicable requirements of Rule 144 (or,
in the case of a Non-Accredited Purchaser, Rule 701) are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rule 144
(and, in the case of a Non-Accredited Purchaser, Rule 701) are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered
offering and otherwise than pursuant to Rule 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration 

  
 -5-

 
is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. 

(j) Purchaser understands that Purchaser may suffer adverse tax consequences as a result of Purchaser’s purchase or
disposition of the Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the purchase or disposition of the Shares and that Purchaser is not relying on the Company for any tax
advice. 
 (k) Purchaser understands that the per share “Exercise Price” for the Shares is intended to
be at least equal to the fair market value of the Company’s Common Stock at the date of grant and that the Company has attempted in good faith to make the fair market value determination in compliance with applicable tax law although there can
be no certainty that the IRS will agree. Purchaser understands that if the IRS does not agree and asserts that the fair market value at the time of grant is higher than the Exercise Price, the IRS could seek to impose greater taxes on Purchaser,
including interest and penalties under Internal Revenue Code Section 409A. 
 5. Restrictive Legends and
Stop-Transfer Orders. 
 (a) Legends. The certificate or certificates representing the
Shares shall bear the following legends (as well as any legends required by applicable U.S. state and federal corporate and securities laws): 
  

	 	(i)	THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO,
OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED UNLESS EFFECTED PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR UNDER ANOTHER EXEMPTION AVAILABLE UNDER THE U.S. SECURITIES ACT
OF 1933 (AS TO WHICH AVAILABILITY THE COMPANY MAY REQUIRE THE SELLER/TRANSFEROR TO PROVIDE AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY). 

  

	 	(ii)	 THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS (SUBJECT TO CERTAIN EXTENSIONS) AFTER THE EFFECTIVE
DATE OF THE ISSUER’S REGISTRATION STATEMENT FILED UNDER THE U.S. SECURITIES ACT OF 1933, AS 

  
 -6-

	 	 
AMENDED, AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. SUCH LOCK-UP PERIOD
IS BINDING ON TRANSFEREES OF THESE SHARES. 

  

	 	(iii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH
IS ON FILE WITH THE SECRETARY OF THE COMPANY. 

 (b) Stop-Transfer Notices. Purchaser
agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it
may make appropriate notations to the same effect in its own records. 
 (c) Refusal to Transfer.
The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right
to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 
 6. No
Employment Rights. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any
reason, with or without cause. 
 7. Lock-Up Agreement. In connection with the initial public offering of the
Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any securities of the Company however or whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not
to exceed 180 days but subject to such extension or extensions as may be required by the underwriters in order to publish research reports while complying with Rule 2711 of the National Association of Securities Dealers, Inc.) from the effective
date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 

8. Data Protection. 

  
 -7-

 (a) To facilitate the administration of the Plan and this Agreement, it will
be necessary for the Company (or its payroll administrators) to collect, hold and process certain personal information about Purchaser and to transfer this data to certain third parties such as brokers with whom Purchaser may elect to deposit any
share capital under the Plan. Purchaser consents to the Company (or its payroll administrators) collecting, holding and processing Purchaser’s personal data and transferring this data to the Company or any other third parties insofar as is
reasonably necessary to implement, administer and manage the Plan. 
 (b) Purchaser understands that Purchaser
may, at any time, view Purchaser’s personal data, require any necessary corrections to it or withdraw the consents herein in writing by contacting the Company, but acknowledges that without the use of such data it may not be practicable for the
Company to administer Purchaser’s involvement in the Plan in a timely fashion or at all and this may be detrimental to Purchaser. 
 9. Miscellaneous. 
 (a) Governing Law.
This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles
of conflicts of law. 
 (b) Entire Agreement; Enforcement of Rights. This Agreement sets forth the
entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be
effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 

(c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable
law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement,
(ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 

(d) Construction. This Agreement is the result of negotiations between and has been reviewed by each of the
parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 

(e) Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed
sufficient when delivered personally or sent by telegram or fax or forty-eight (48) hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such
party’s address as set forth below or as subsequently modified by written notice. 

  
 -8-

 (f) Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. 
 (g) Successors and Assigns. The rights and benefits of this Agreement shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. The rights and
obligations of Purchaser under this Agreement may only be assigned with the prior written consent of the Company.

 BRIGHT SOURCE ENERGY, INC. 

2006 STOCK PLAN 
 STOCK OPTION AGREEMENT 
 FOR OPTIONS GRANTED UNDER SECTION
102(b)(2) 
 OF THE ISRAELI INCOME TAX ORDINANCE 

TO EMPLOYEES, OFFICERS OR DIRECTORS 
 AS 102 CAPITAL GAINS TRACK OPTIONS 
 1. Grant of Option.
Bright Source Energy, Inc., a Delaware corporation (the “Company”), hereby grants to «Optionee» (“Optionee”), an option (the “Option”) to purchase the total number of shares of Common
Stock (the “Shares”) set forth in the Notice of Stock Option Grant (the “Notice”), at the exercise price per Share set forth in the Notice (the “Exercise Price”) subject to the terms, definitions
and provisions of the Bright Source Energy, Inc. 2006 Stock Plan (the “Plan”) and the Appendix thereto for Israeli Taxpayers (the “Appendix”) adopted by the Company, which is incorporated in this Agreement by
reference. Unless otherwise defined in this Agreement, the terms used in this Agreement shall have the meanings defined in the Plan. 
 2. Designation of Option. This Option is granted subject to the terms and conditions of Section 102(b)(2) of the Income Tax Ordinance (New Version) - 1961, the Plan, which is
incorporated herein by reference, and the Trust Agreement entered into between the Company and ESOP Trust Company (the “Trustee”). The Options are granted as a 102 Capital Gains Track Grant. 

The Options will be registered in the name of the Trustee as required by the ITO to qualify under Section 102, for the benefit of
Optionee. Optionee shall comply with the ITO, the Rules, and the terms and conditions of the Trust Agreement entered into between the Company and the Trustee. The Trustee will hold the Options or the Shares to be issued upon exercise of the Options
for the Required Holding Period, as set forth in the Appendix. The Optionee hereby undertakes to release the Trustee from any liability in respect of any action or decision duly taken and executed in good faith in relation to the requirements of the
Plan, the Appendix and the ITO, or any Option granted, or Share issued, in the name of the Trustee thereunder. The Optionee hereby confirms that s/he shall execute any and all documents which the Company or the Trustee may reasonably determine to be
necessary in order to comply with the ITO, and particularly the Rules. 
 3. Exercise of Option. This Option shall
be exercisable during its term in accordance with the Vesting/Exercise Schedule set out in the Notice and with the provisions of Section 9 of the Plan as follows: 

 (a) Right to Exercise. 

(i) This Option may not be exercised for a fraction of a share. 

(ii) In the event of Optionee’s death, disability or other termination of employment, the exercisability of the
Option is governed by Section 5 below, subject to the limitations contained in this Section 3. 
 (iii)
In no event may this Option be exercised after the Expiration Date of the Option as set forth in the Notice. 

(b) Method of Exercise. 

(i) This Option shall be exercisable by execution and delivery of the Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the “Exercise Agreement”) or of any other form of written notice approved for such purpose by the Company which shall state Optionee’s election to exercise the Option, the number
of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company pursuant to the provisions of the
Plan. Such written notice shall be signed by Optionee and shall be delivered to the Company by such means as are determined by the Plan Administrator in its discretion to constitute adequate delivery. The written notice shall be accompanied by
payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price. 
 (ii) The Company will notify the Trustee of any exercise of Options. If such notification is delivered during the Required Holding Period, the Shares issued upon the exercise of the Options shall be
issued in the name of the Trustee, and held in trust on Optionee’s behalf by the Trustee. In the event that such notification is delivered after the end of the Required Holding Period, the Shares issued upon the exercise of the Options shall
either (i) be issued in the name of the Trustee, subject to the Trustee’s prior written consent, or (ii) be transferred to the Optionee directly, provided that Optionee first complies with the provisions of Section 7 below. In
the event that Optionee elects to have the Shares transferred to Optionee without selling such Shares, Optionee shall become liable to pay taxes immediately in accordance with the provisions of the ITO. 

(iii) As a condition to the exercise of this Option and as further set forth in Section 11 of the Plan, Optionee
agrees to make adequate provision for U.S. federal, state or other tax withholding obligations, if any, which arise upon the vesting or exercise of the Option, or disposition of Shares, whether by withholding, direct payment to the Company, or
otherwise. 
 (iv) The Company is not obligated, and will have no liability for failure, to issue or deliver any
Shares upon exercise of the Option unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. This Option may not be exercised until such time as the
Plan has been approved by the stockholders of the Company, or if the issuance of 

  
 4 

 
such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable Israeli or U.S. federal or state securities or other law or
regulation, including any rule under Part 221 of Title 12 of the U.S. Code of Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company may require Optionee to make any
representation and warranty to the Company as may be required by the Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on the date on which the Option is exercised with respect
to such Shares. 
 4. Method of Payment. Payment of the Exercise Price shall be by any of the following, or a
combination of the following, at the election of Optionee: 
 (a) cash or check; 

(b) cancellation of indebtedness; or 

(c) following the date, if any, upon which the Common Stock is a Listed Security, and if the Company is at such time
permitting “same day sale” cashless brokered exercises, delivery of a properly executed exercise notice together with irrevocable instructions to a broker participating in such cashless brokered exercise program to deliver promptly to the
Company the amount required to pay the exercise price (and applicable withholding taxes). 
 5. Termination of
Relationship; Early Termination of Option. Following the date of termination of Optionee’s Continuous Service Status for any reason (the “Termination Date”), Optionee may exercise the Option only as set forth in the
Notice and this Section 5. To the extent that Optionee is not entitled to exercise this Option as of the Termination Date, or if Optionee does not exercise this Option within the Termination Period set forth in the Notice or the termination
periods set forth below, the Option shall terminate in its entirety. In no event, may any Option be exercised after the Expiration Date of the Option as set forth in the Notice. 

(a) Termination. In the event of termination of Optionee’s Continuous Service Status other than as a
result of Optionee’s disability or death or for Cause (as defined in the Plan), Optionee may, to the extent Optionee is vested in the Option Shares at the Termination Date, exercise this Option during the Termination Period set forth in the
Notice. 
 (b) Other Terminations of Relationship. In connection with any termination other than a
termination covered by Section 5(a), Optionee may exercise the Option only as described below: 
 (i)
Termination upon Disability of Optionee. In the event of termination of Optionee’s Continuous Service Status as a result of Optionee’s disability, Optionee may, but only within twelve months from the Termination Date,
exercise this Option to the extent Optionee was vested in the Option Shares as of such Termination Date. 
 (ii)
Death of Optionee. In the event of the death of Optionee (a) during the term of this Option and while an Employee or Consultant of the Company and having been in Continuous Service Status since the date of grant of the Option, or
(b) within thirty (30)

  
 -3-

 
days after Optionee’s Termination Date, the Option may be exercised at any time within twelve months following the date of death by Optionee’s estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent Optionee was vested in the Option as of the Termination Date. 
 (iii) Termination for Cause. In the event Optionee’s Continuous Service Status is terminated for Cause, the Option shall terminate immediately upon such termination for Cause as set
forth in Section 9(b)(iv) of the Plan. In the event Optionee’s employment or consulting relationship with the Company is suspended pending investigation of whether such relationship shall be terminated for Cause, all Optionee’s rights
under the Option, including the right to exercise the Option, shall be suspended during the investigation period, also as set forth in Section 9(b)(iv) of the Plan. 

(c) Termination of Option. This Option may terminate prior to its Expiration Date and prior to the dates
specified under Section 5(a) and (b) above under certain circumstances as set forth in Section 13 of the Plan. 

6. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of
descent or distribution and may be exercised during the lifetime of Optionee only by him or her. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and assigns of Optionee. 

7. Tax Consequences. The Company has not provided any tax advice with respect to this Option or the disposition of the
Shares. Optionee should obtain advice from an appropriate independent professional adviser with respect to the taxation implications of the grant, exercise, assignment, release, cancellation or any other disposal of this Option and on any subsequent
sale or disposition of the Shares. Any tax consequences arising from the grant or exercise of any Option, from the payment for Shares covered thereby, or from any other event or act (of the Company, and/or its Affiliates, and the Trustee or
Optionee) relating to the Options or Shares issued upon exercise thereof, shall be borne solely by Optionee. The Company and/or its Affiliates, and/or the Trustee shall withhold taxes according to the requirements under the applicable laws, rules,
and regulations, including withholding taxes at source. Furthermore, Optionee agrees to indemnify the Company and/or its Affiliates and/or the Trustee and hold them harmless against and from any and all liability for any such tax or interest or
penalty thereon, including without limitation, liabilities relating to the necessity to withhold, or to have withheld, any such tax from any payment made to Optionee for which Optionee is responsible. The Company or any of its Affiliates and the
Trustee may make such provisions and take such steps as it/they may deem necessary or appropriate for the withholding of all taxes required by law to be withheld with respect to Options granted under the Plan and the exercise thereof, including, but
not limited, to (i) deducting the amount so required to be withheld from any other amount then or thereafter payable to Optionee, including by deducting any such amount from Optionee’s salary or other amounts payable to Optionee, to the
maximum extent permitted under law and/or (ii) requiring Optionee to pay to the Company or any of its Affiliates the amount so required to be withheld as a condition of the issuance, delivery, distribution or release of any Shares and/or
(iii) by causing the exercise and sale of any Options or Shares held by on behalf of Optionee to cover such liability, up to the amount required to satisfy minimum statutory withholding 

  
 -4-

 
requirements. In addition, Optionee will be required to pay any amount that exceeds the tax to be withheld and transferred to the tax authorities, pursuant to applicable Israeli tax regulations.

 (a) Notice to U.S. Taxpayers. The per share Exercise Price of the Option is intended to be at
least equal to the fair market value of the Company’s Common Stock at the date of grant. The Company has attempted in good faith to make the fair market value determination in compliance with applicable tax law although there can be no
certainty that the IRS will agree. If the IRS does not agree and asserts the fair market value at the time of grant is higher than the Exercise Price, the IRS could seek to impose greater taxes on Optionee, including interest and penalties under
Internal Revenue Code Section 409A if Optionee is a U.S. taxpayer. While the Company thinks this is an unlikely event, the Company cannot provide absolute assurance and Optionee may want to consult Optionee’s own tax adviser with any
questions.

 EXHIBIT A 
 BRIGHT SOURCE ENERGY, INC. 
 2006 STOCK PLAN 

EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 

FOR OPTIONS GRANTED UNDER SECTION 102(b)(2) 
 OF THE ISRAELI INCOME TAX ORDINANCE 
 TO EMPLOYEES, OFFICERS OR DIRECTORS

 This Agreement (“Agreement”) is made as of
                    , by and between Bright Source Energy, Inc., a Delaware corporation (the “Company”), and
«Optionee» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the Company’s 2006 Stock Plan (the “Plan”) or
the Appendix thereto for Israeli Taxpayers (the “Appendix”). 
 1. Exercise of Option. Subject to
the terms and conditions hereof, Purchaser hereby elects to exercise his or her option to purchase                      shares of the Common
Stock (the “Shares”) of the Company under and pursuant to the Plan and the Appendix and the Stock Option Agreement granted «GrantDate» (the “Option Agreement”). The purchase price for the Shares shall be
$«ExercisePrice» per Share for a total purchase price of $                    . The term “Shares” refers to the
purchased Shares and all securities received in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution and delivery of
this Agreement in accordance with the provisions of Section 3(b) of the Option Agreement. On such date, the Company will deliver to the Trustee, for the benefit of the Purchaser, a certificate representing the Shares to be purchased for the
benefit of the Purchaser (which shall be issued in the Trustee’s name) against payment of the exercise price therefor by Purchaser by any method listed in Section 4 of the Option Agreement. 

3. Limitations on Transfer. In addition to any other limitation on transfer created by applicable securities laws,
Purchaser shall not assign, encumber or dispose of any interest in the Shares, or cause the Trustee to perform any of the foregoing, except in compliance with the provisions below, the terms of the Option Agreement and Appendix, and applicable
securities laws. 

 (a) Right of Repurchase. Purchaser acknowledges that the
Company shall have the right, but not the obligation, during the 60 days after the termination of Purchaser’s Continuous Service Status for any reason or after exercise of the Option if the Option is exercised after termination of
Purchaser’s Continuous Service Status for any reason, to repurchase the Shares. The repurchase price shall be the Fair Market Value of those Shares as of the date of the Termination. The Fair Market Value per Share will be determined as set
forth in Section 3(c)(ii) of this Agreement. The repurchase price shall be paid in cash. 
 (b) Right
of First Refusal. Before any Shares held by the Trustee on behalf of the Purchaser, the Purchaser or any transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or otherwise
transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section 3(b) (the “Right of First
Refusal”). 
 (i) Notice of Proposed Transfer. The Holder of the Shares shall deliver to
the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed
Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder shall offer the Shares at the same price (the “Offered
Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 
 (ii) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder,
elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (iii) below. 

(iii) Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by
the Company or its assignee(s) under this Section 3(b) shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of
Directors of the Company in good faith. 
 (iv) Payment. Payment of the Purchase Price shall be
made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the
times set forth in the Notice, after deduction of all amounts required by mandatory withholding laws and regulations. 
 (v) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as
provided in this Section 3(b), then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 60 days after the
date of the Notice and provided further that any such sale or other transfer is effected in accordance with any applicable 

 
securities laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the
Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the
Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

(vi) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 3(b)
notwithstanding, the transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of Purchaser’s Immediate Family shall
be exempt from the provisions of this Section 3(b), provided however, that any such transfer shall be subject to the restrictions and conditions set forth in the Appendix and the Option Agreement. “Immediate Family” as used
herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall
be no further transfer of such Shares except in accordance with the terms of this Section 3. 
 (c)
Involuntary Transfer. 
 (i) Company’s Right to Purchase upon Involuntary Transfer.
In the event, at any time after the date of this Agreement, of any transfer by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above)
of all or a portion of the Shares by the record holder thereof, the Company shall have an option to purchase all of the Shares transferred at the Fair Market Value of the Shares on the date of transfer. Upon such a transfer, the person acquiring the
Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by the person
acquiring the Shares. 
 (ii) Price for Involuntary Transfer. With respect to any stock to be
transferred pursuant to Sections 3(a) or 3(c)(i), the Fair Market Value per Share shall be a price set by the Board of Directors of the Company in good faith using a reasonable valuation method in a reasonable manner in accordance with
Section 409A of the Code. The Company shall notify Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the
Purchaser does not agree with the valuation as determined by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the
Purchaser and whose fees shall be borne equally by the Company and the Purchaser. 
 (d)
Assignment. The right of the Company to purchase any part of the Shares may be assigned in whole or in part to any stockholder or stockholders of the Company or other persons or organizations. 

 (e) Restrictions Binding on Transferees. All transferees of
Shares or any interest therein will receive and hold such Shares or interest subject to the provisions of this Agreement. Any sale or transfer of the Company’s Shares shall be void unless the provisions of this Agreement are satisfied.

 (f) Termination of Rights. The right of repurchase granted by the Company in Section 3(a)
above, the right of first refusal granted the Company by Section 3(b) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(c) above shall terminate upon the first sale of
Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the U.S. Securities and Exchange Commission under the U.S. Securities Act of 1933, as amended (the “U.S. Securities
Act”). Upon termination of the rights to repurchase and the right of first refusal described in Sections 3(a), 3(b) and 3(c) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request,
without the legend referred to in Section 5(a)(ii) herein and delivered to Purchaser. 
 4. Investment and Taxation
Representations. In connection with the purchase of the Shares, Purchaser represents to the Company the following: 
 (a) Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire
the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the U.S. Securities Act or under
any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity. 
 (b) Purchaser understands that the Shares have not been registered under the U.S. Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona
fide nature of Purchaser’s investment intent as expressed herein. 
 (c) Purchaser further acknowledges and
understands that the securities must be held indefinitely unless they are subsequently registered under the U.S. Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the Company is
under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or such registration is
not required in the opinion of counsel for the Company. 
 (d) Purchaser is familiar with the provisions of
Rule 144 promulgated under the U.S. Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such
issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144, which
rule requires, among other things, that the Company be subject to the reporting requirements of the U.S. Securities Exchange Act of 

 
1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified time periods, and under certain circumstances, that resales
of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the restrictions set forth in paragraph (e) below. 

(e) Purchaser further understands that in the event all of the applicable requirements of Rule 144 are not satisfied,
registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rule 144 is not exclusive, the Staff of the U.S. Securities and Exchange
Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. 

(f) Purchaser understands that Purchaser may suffer adverse tax consequences as a result of Purchaser’s purchase or
disposition of the Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the purchase or disposition of the Shares and that Purchaser is not relying on the Company for any tax
advice. 
 (g) Purchaser understands that the per share “Exercise Price” for the Shares is intended to
be at least equal to the fair market value of the Company’s Common Stock at the date of grant and that the Company has attempted in good faith to make the fair market value determination in compliance with applicable tax law although there can
be no certainty that the IRS will agree. Purchaser understands that if the IRS does not agree and asserts that the fair market value at the time of grant is higher than the Exercise Price, the IRS could seek to impose greater taxes on Purchaser if
Purchaser is a U.S. taxpayer, including interest and penalties under Internal Revenue Code Section 409A. 
 5.

Purchaser’s involvement in the Plan in a timely fashion or at all and this may be detrimental to Purchaser.
