 3. Stock Subject to the 2012 Equity Plan. 

(a) Stock Subject to the 2012 Equity Plan. Subject to the provisions of Section 13 of the 2012 Equity
Plan, the maximum aggregate number of Shares that may be issued under the 2012 Equity Plan is 6,500,000 Shares, plus (i) any Shares that, as of the Registration Date, have been 

  
 -5-

 
reserved but not issued pursuant to any awards granted under the Company’s 2007 Stock Incentive Plan (the “Existing Plan”) and are not subject to any awards granted
thereunder, and (ii) any Shares subject to awards under the Existing Plan that otherwise would have been returned to the Existing Plan after the Registration Date on account of the expiration, cancellation or forfeiture of awards granted
thereunder, with the maximum number of Shares to be added to the 2012 Equity Plan pursuant to clauses (i) and (ii) equal to 7,631,268 Shares. The Shares may be authorized, but unissued, or reacquired Common Stock. Notwithstanding the
foregoing and, subject to adjustment as provided in Section 13, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in this Section 3(a), plus, to the
extent allowable under Section 422 of the Code and the Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the 2012 Equity Plan pursuant to Sections 3(b) and 3(c). 

(b) Automatic Share Reserve Increase. The number of Shares available for issuance under the 2012 Equity Plan will be increased on
the first day of each Fiscal Year beginning with the 2012 Fiscal Year, in an amount equal to the least of (i) 6,000,000 Shares, (ii) four percent (4%) of the outstanding Shares on the last day of the immediately preceding Fiscal Year
or (iii) such number of Shares determined by the Board.

surrendered pursuant to an Exchange Program or becomes unexercisable without having been exercised or, with respect to Restricted Stock, Restricted Stock Units, Performance Units or Performance Shares, is forfeited to or repurchased by the Company
due to failure to vest, the unpurchased Shares (or for Awards other than Options or Stock Appreciation Rights the forfeited or repurchased Shares), which were subject thereto will become available for future grant or sale under the 2012 Equity Plan
(unless the 2012 Equity Plan has terminated). Notwithstanding the foregoing (and except with respect to Shares of Restricted Stock that are forfeited rather than vesting), Shares that have actually been issued under the 2012 Equity Plan under any
Award will not be returned to the 2012 Equity Plan and will not become available for future distribution under the 2012 Equity Plan; provided, however, that if Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance
Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares will become available for future grant under the 2012 Equity Plan. Shares used to pay the exercise price of an Award or to satisfy the tax
withholding obligations related to an Award will become available for future grant or sale under the 2012 Equity Plan. To the extent an Award under the 2012 Equity Plan is paid out in cash rather than Shares, such cash payment will not result in
reducing the number of Shares available for issuance under the 2012 Equity Plan. 
 4. Administration of the 2012 Equity
Plan. 
 (a) Procedure. 
 (i) Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the 2012 Equity Plan. 

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder
as “performance-based compensation” within the 

  
 -6-

 
meaning of Section 162(m) of the Code, the 2012 Equity Plan will be administered by a Committee of two (2) or more “outside directors” within the meaning of
Section 162(m) of the Code. 
 (iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as
exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3.

or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine; 
 (vi) to construe and interpret the terms of the 2012 Equity Plan and Awards granted pursuant to the 2012 Equity Plan; 
 (vii) to prescribe, amend and rescind rules and regulations relating to the 2012 Equity Plan, including rules and regulations established for the purpose of satisfying applicable foreign laws, for
qualifying for favorable tax treatment under applicable foreign laws or facilitating compliance with foreign laws; sub-plans may be created for any of these purposes; 
 (viii) to modify or amend each Award (subject to Section 18 of the 2012 Equity Plan), including but not limited to the discretionary authority to extend the post-termination exercisability period of
Awards and to extend the maximum term of an Option (subject to Section 6(b) of the 2012 Equity Plan regarding Incentive Stock Options); 
 (ix) to allow Participants to satisfy withholding tax obligations in such manner as prescribed in Section 14 of the 2012 Equity Plan;

 (xi) to allow a Participant to defer the receipt of
the payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award; and 
 (xii) to
make all other determinations deemed necessary or advisable for administering the 2012 Equity Plan. 
 (c) Effect of
Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards. 

(d) Exchange Program. Notwithstanding the anything in this Section 4, the Committee shall not implement an Exchange Program
without the approval of the holders of a majority of the Shares that are present in person or by proxy and entitled to vote at any annual or special meeting of Company’s shareholders. 

(e) Delegation by the Committee. The Committee, in its sole discretion and on such terms and conditions as it may provide, may
delegate all or any part of its authority and powers under the 2012 Equity Plan to one or more Directors or officers of the Company; provided, however, that the Committee may not delegate its authority and powers (a) with respect to an Officer
or (b) in any way which would jeopardize the 2012 Equity Plan’s qualification under Code Section 162(m) or Rule 16b-3. 
 5. Award Eligibility and Limitations. 
 (a) Award Eligibility.
Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 

(b) Award Limitations. The following limits shall apply to the grant of any Award if, at the time of grant, the Company is a
“publicly held corporation” within the meaning of Section 162(m) of the Code: 
 (i) Options and Stock
Appreciation Rights. Subject to adjustment as provided in Section 13, no Employee shall be granted within any fiscal year of the Company one or more Options or Stock Appreciation Rights, which in the aggregate cover more than 750,000 Shares
reserved for issuance under the 2012 Equity Plan; provided, however, that in connection with an Employee’s initial service as an Employee, an Employee may be granted Options or Stock Appreciation Rights, which in the aggregate cover up to an
additional 1,500,000 Shares reserved for issuance under the 2012 Equity Plan. 
 (ii) Restricted Stock and Restricted Stock
Units. Subject to adjustment as provided in Section 13, no Employee shall be granted within any fiscal year of the Company one or more awards of Restricted Stock or Restricted Stock Units, which in the aggregate cover more than 750,000
Shares reserved for issuance under the 2012 Equity Plan; provided, however, that in connection with an Employee’s initial service as an Employee, an Employee may be granted 

  
 -8-

 
Restricted Stock or Restricted Stock Units s, which in the aggregate cover up to an additional 750,000 Shares reserved for issuance under the 2012 Equity Plan. 

(iii) Performance Units and Performance Shares. Subject to adjustment as provided in Section 13, no Employee shall receive
Performance Units or Performance Shares having a grant date value (assuming maximum payout) greater than two million dollars ($2 million) or covering more than 500,000 Shares, whichever is greater; provided, however, that in connection with an
Employee’s initial service as an Employee, an Employee may receive Performance Units or Performance Shares having a grant date value (assuming maximum payout) of up to an additional amount equal five million dollars ($5 million) or covering up
to 1,000,000 Shares, whichever is greater. No Participant may be granted more than one award of Performance Units or Performance Shares for the same Performance Period.] 
 6. Stock Options. 
 (a) Limitations. Each Option will be designated
in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For
purposes of this Section 6(a), Incentive Stock Options will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted.
With respect to the Committee’s authority in Section 4(b)(viii), if, at the time of any such extension, the exercise price per Share of the Option is less than the Fair Market Value of a Share, the extension shall, unless otherwise
determined by the Committee, be limited to the earlier of (1) the maximum term of the Option as set by its original terms, or (2) ten (10) years from the grant date. Unless otherwise determined by the Committee, any extension of the
term of an Option pursuant to this Section 4(b)(viii) shall comply with Code Section 409A to the extent necessary to avoid taxation thereunder. 
 (b) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term will be ten (10) years from the date of grant or such
shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of
the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award
Agreement. 
 (c) Option Exercise Price and Consideration. 

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined
by the Administrator, subject to the following: 
 (1) In the case of an Incentive Stock Option 

  
 -9-

 (A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns
stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market
Value per Share on the date of grant. 
 (B) granted to any Employee other than an Employee described in paragraph
(A) immediately above, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (2) In the case of a Nonstatutory Stock Option, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(3) Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than one hundred percent
(100%) of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code. 
 (ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must
be satisfied before the Option may be exercised. 
 (iii) Form of Consideration. The Administrator will determine the
acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration for
both types of Options may consist entirely of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender
equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole
discretion; (5) consideration received by the Company under a broker-assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the 2012 Equity Plan; (6) by net
exercise; (7) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or (8) any combination of the foregoing methods of payment. 

(d) Exercise of Option. 
 (i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the 2012 Equity Plan and at such times and under such conditions as
determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 
 An Option will be deemed exercised when the Company receives: (i) a notice of exercise (in such form as the Administrator may specify from time to time) from the person entitled to exercise the
Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any 

  
 -10-

 
consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the 2012 Equity Plan. Shares issued upon exercise of an Option will be issued in the
name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent
of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such
Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the 2012 Equity Plan. 

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the
Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on
the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three
(3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of
the Option will revert to the 2012 Equity Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to
the 2012 Equity Plan. 
 (iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result
of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination.
Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the 2012 Equity Plan. If after
termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the 2012 Equity Plan. 

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the
Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the Option be exercised later than the expiration of the term of such Option
as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been
designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the
laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the

  
 -11-

 
Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the 2012
Equity Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the 2012 Equity Plan. 

7. Restricted Stock. 
 (a) Grant of Restricted Stock. Subject to the terms and provisions of the 2012 Equity Plan, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service
Providers in such amounts as the Administrator, in its sole discretion, will determine. 
 (b) Restricted Stock
Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will
determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted Stock until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this Section 7 or the Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or
hypothecated until the end of the applicable Period of Restriction. 
 (d) Other Restrictions. The Administrator, in its
sole discretion, may impose such other restrictions on Shares of Restricted Stock as it may deem advisable or appropriate. 

(e) Removal of Restrictions. Except as otherwise provided in this Section 7, Shares of Restricted Stock covered by each
Restricted Stock grant made under the 2012 Equity Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The Administrator, in its
discretion, may accelerate the time at which any restrictions will lapse or be removed. 
 (f) Voting Rights. During the
Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 

(g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will
be entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same
restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 

(h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which
restrictions have not lapsed will revert to the Company and again will become available for grant under the 2012 Equity Plan.

 8. Restricted Stock Units. 

(a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the
Administrator determines that it will grant Restricted Stock Units under the 2012 Equity Plan, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions (if any) related to the grant, including the number of
Restricted Stock Units. 
 (b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its
discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of
Company-wide, business unit, or individual goals (including, but not limited to, continued employment), or any other basis (including the passage of time) determined by the Administrator in its discretion. 

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a
payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a
payout. 
 (d) Dividend Equivalents. The Administrator may, in its sole discretion, award dividend equivalents in
connection with the grant of Restricted Stock Units that may be settled in cash, in Shares of equivalent value, or in some combination thereof. 
 (e) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made upon the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in
its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or a combination of both. 
 (f)
Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the Company. 
 9. Stock Appreciation Rights. 
 (a) Grant of Stock Appreciation
Rights. Subject to the terms and conditions of the 2012 Equity Plan, a Stock Appreciation Right may be granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. 

(b) Number of Shares. The Administrator will have complete discretion to determine the number of Stock Appreciation Rights granted
to any Service Provider. 
 (c) Exercise Price and Other Terms. The per share exercise price for the Shares to be issued
pursuant to exercise of a Stock Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the
provisions of the 2012 Equity Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the 2012 Equity Plan. 

  
 -13-

 (d) Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be
evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 

(e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the 2012 Equity Plan will expire upon the
date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(b) relating to the maximum term and Section 6(d) relating to exercise also will apply
to Stock Appreciation Rights. 
 (f) Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation
Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The
difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (ii) The number
of Shares with respect to which the Stock Appreciation Right is exercised. 
 At the discretion of the Administrator, the
payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or in some combination thereof. 

10. Performance Units and Performance Shares. 
 (a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service Providers at any time and from time to time, as will be determined by the Administrator, in
its sole discretion. The Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to each Participant. 
 (b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator on or before the date of grant. Each Performance Share will have an
initial value equal to the Fair Market Value of a Share on the date of grant. 
 (c) Performance Objectives and Other
Terms. The Administrator will set Performance Goals or other vesting provisions (including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the
number or value of Performance Units/Shares that will be paid out to the Service Providers. The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award
of Performance Units/Shares will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance
objectives based upon the achievement of Company-wide, divisional, or individual goals, applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 

  
 -14-

 (d) Measurement of Performance Goals. Performance Goals shall be established by the
Committee on the basis of targets to be attained (“Performance Targets”) with respect to one or more measures of business or financial performance (each, a “Performance Measure”), subject to the following:

 (i) Performance Measures. For each Performance Period, the Committee shall establish and set forth in writing the
Performance Measures, if any, and any particulars, components and adjustments relating thereto, applicable to each Participant. The Performance Measures, if any, will be objectively measurable and will be based upon the achievement of a specified
percentage or level in one or more objectively defined and non-discretionary factors preestablished by the Committee. Performance Measures may be one or more of the following, as determined by the Committee: (i) total revenue; (ii) return
on revenue; (iii) gross profit; (iv) EBITDA, or earnings before interest, taxes, depreciation and/or amortization; (v) income from continuing operations; (vi) income before from operations (pre-tax); (vii) net income (loss);
(viii) net income excluding amortization of intangible assets, depreciation and impairment of goodwill and intangible assets and/or excluding charges attributable to the adoption of new accounting pronouncements; (ix) raising of equity;
(x) securing project financing and project financing activity and milestones; (xi) operating margin or profit margin; (xii) capital expenditure targets, operating expense and overhead expense targets, reductions and savings and
expense management; (xiii) return on assets (gross or net), return on investment, return on capital, or return on shareholder equity; (xiv) cash flow, free cash flow, cash flow return on investment (discounted or otherwise), net cash
provided by operations, or cash flow in excess of cost of capital; (xv) stock price or total stockholder return; (xvi) earnings or book value per share (basic or diluted); (xvii) economic value created; (xviii) strategic business
criteria, consisting of one or more objectives based on meeting specified market penetration or market share, geographic business expansion; (xix) objective goals relating to divestitures, joint ventures, mergers, acquisitions and similar
transactions; (xx) new project opportunities consisting of one or more objectives based upon achieving new feedstock agreements, site acquisition, permitting and other new project milestones; (xxi) construction projects consisting of one
or more objectives based upon meeting project completion timing milestones, project budget, or equipment performance; (xxii) objective goals relating to staff management, results from staff attitude and/or opinion surveys, staff satisfaction
scores, staff safety, staff accident and/or injury rates, headcount, performance management, completion of critical staff training initiatives; (xxiii) corporate overhead and corporate management objective goals relating to human resources,
information technology, insurance, accounting, finance and office administration; (xxiv key regulatory objectives; and (xxv) enterprise resource planning. 
 (ii) Committee Discretion on Performance Measures. As determined in the discretion of the Committee, the Performance Measures for any Performance Period may (a) differ from Participant to
Participant and from Award to Award, (b) be based on the performance of the Company as a whole or the performance of a specific Participant or one or more subsidiaries, divisions, departments, regions, stores, segments, products, functions or
business units of the Company or individual project company, (c) be measured on a per share, per capita, per unit, per square foot, per employee, per store basis, and/or other objective basis (d) be measured on a pre-tax or after-tax
basis, and (e) be measured on an absolute basis or in relative terms (including, but not limited to, the passage of time and/or against other companies, financial metrics and/or an index). Without limiting the foregoing, the Committee shall
adjust any performance criteria, Performance Measures or other feature of an Award that relates to or is wholly or partially based on the number 

  
 -15-

 
of, or the value of, any stock of the Company, to reflect any stock dividend or split, repurchase, recapitalization, combination, or exchange of shares or other similar changes in such stock.
Awards that are not intended by the Company to comply with the performance-based compensation exception under Code Section 162(m) may take into account other factors (including subjective factors). 

(e) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares
will be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding Performance Goals or other vesting
provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any Performance Goals or other vesting provisions for such Performance Unit/Share. 

(f) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made upon the time
set forth in the applicable Award Agreement. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance
Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 
 (g) Cancellation of
Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the 2012 Equity Plan. 

11. Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of
Awards granted hereunder will be suspended during any unpaid leave of absence unless contrary to Applicable Law. A Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Participant’s employer
or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave
is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Participant’s employer is not so guaranteed, then six (6) months following the first (1st) day of such leave any Incentive Stock Option held by the
Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 
 12. Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, such Award will contain such additional terms and conditions as
the Administrator deems appropriate. 
 13. Adjustments; Dissolution or Liquidation; Merger or Change in Control.

 (a) Adjustments. In the event of a stock split, reverse stock split, stock dividend, combination, consolidation,
recapitalization (including a recapitalization through a large 

  
 -16-

 
nonrecurring cash dividend) or reclassification of the Shares, subdivision of the Shares, a rights offering, a reorganization, merger, spin-off, split-up, repurchase, or exchange of Common Stock
or other securities of the Company or other significant corporate transaction, or other change affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be
made available under the 2012 Equity Plan, will, in such manner as it may deem equitable, adjust the number, kind and class of securities that may be delivered under the 2012 Equity Plan and/or the number, class, kind and price of securities covered
by each outstanding Award, and the numerical Share limits in Section 3 of the 2012 Equity Plan. Notwithstanding the forgoing, all adjustments under this Section 13 shall be made in a manner that does not result in taxation under Code
Section 409A. 
 (b) Dissolution or Liquidation. In the event of the proposed winding up, dissolution or liquidation
of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the
consummation of such proposed action. 
 (c) Change in Control. In the event of a merger or Change in Control, each
outstanding Award will be treated as the Administrator determines, including, without limitation, that each Award be assumed, cancelled or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. The Administrator will not be required to treat all Awards similarly in the transaction. 
 Except as set
forth in an Award Agreement, in the event that the successor corporation does not assume or substitute for the Award, the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation
Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all Performance
Goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a
Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option
or Stock Appreciation Right will terminate upon the expiration of such period. 
 For the purposes of this subsection (c), an
Award will be considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or
other securities or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the
successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Unit or Performance Share, for each Share subject to such
Award, to be solely common stock of the 

  
 -17-

 
successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in Control. 

Notwithstanding anything in this Section 13(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of
one or more Performance Goals will not be considered assumed if the Company or its successor modifies any of such Performance Goals without the Participant’s consent; provided, however, a modification to such Performance Goals only to reflect
the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption. 
 (d) Outside Director Awards. Except as set forth in an Award Agreement, with respect to Awards granted to an Outside Director that are assumed or substituted for, if on the date of or following
such assumption or substitution the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant (unless such resignation is at the
request of the acquirer), then the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares which would not otherwise be vested or
exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Performance Units and Performance Shares, all Performance Goals or other vesting criteria will be deemed achieved at one hundred percent
(100%) of target levels and all other terms and conditions met. 
 14. Tax. 

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or prior to
any time the Award or Shares are subject to taxation, the Company and/or the Participant’s employer will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy
federal, state, local, foreign or other taxes (including the Participant’s FICA obligation or social insurance contributions) required to be withheld with respect to such Award (or exercise thereof). 

(b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from
time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (a) paying cash, (b) electing to have the Company withhold otherwise deliverable cash or Shares having a Fair
Market Value equal to the minimum statutory amount required to be withheld (to the extent required to avoid adverse accounting consequences), or (c) delivering to the Company already-owned Shares having a Fair Market Value equal to the minimum
statutory amount required to be withheld to the extent required to avoid adverse accounting consequences or Shares having a Fair Market Value in excess of such amount that have been held for such period required to avoid adverse accounting
consequences. Except as otherwise determined by the Administrator, the Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 

(c) Compliance With Code Section 409A. Awards will be designed and operated in such a manner that they are either exempt from
the application of, or comply with, the requirements of Code Section 409A such that the grant, payment, settlement or deferral will not be 

  
 -18-

 
subject to the additional tax or interest applicable under Code Section 409A. The 2012 Equity Plan and each Award Agreement under the 2012 Equity Plan is intended to meet
the requirements of Code Section 409A (or an exemption therefrom) and will be construed and interpreted in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award
or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award will be granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A (or an exemption therefrom), such that
the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A. In no event will the Company be responsible for or reimburse a Participant for any taxes or other penalties
incurred as a result of applicable of Code Section 409A. 
 15. No Effect on Employment or Service. Neither the 2012
Equity Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company, or (if different) the Participant’s employer, nor will they interfere in
any way with the Participant’s right or the Participant’s employer’s right to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 

16. Date of Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the
determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time after the date of such grant. 

17. Term of 2012 Equity Plan. Subject to Section 21 of the 2012 Equity Plan, the 2012 Equity Plan will become effective upon
the earlier of its adoption by the Board or the Company’s shareholders. It will continue in effect for a term of ten (10) years from such effective date, unless terminated earlier under Section 18 of the 2012 Equity Plan. 

18. Amendment and Termination of the 2012 Equity Plan. 
 (a) Amendment and Termination. The Committee may at any time amend, alter, suspend or terminate the 2012 Equity Plan. 
 (b) Stockholder Approval. The Company will obtain stockholder approval of any 2012 Equity Plan amendment to the extent necessary and desirable to comply with Applicable Laws. 

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the 2012 Equity Plan will impair
the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the 2012 Equity Plan will not affect the
Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the 2012 Equity Plan prior to the date of such termination. 
 19. Conditions Upon Issuance of Shares. 
 (a) Legal Compliance.
Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company
with respect to such compliance. 

  
 -19-

 (b) Investment Representations. As a condition to the exercise of an Award, the
Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required. 
 20. Inability to Obtain Authority. The
inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of
any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained. 
 21. Stockholder Approval. The 2012 Equity Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the 2012 Equity Plan is adopted by the
Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 
 22.
Governing Law. The 2012 Equity Plan and all Awards hereunder shall be construed in accordance with and governed by the laws of the State of California, but without regard to its conflict of law provisions.

 EXHIBIT A 

TERMS AND CONDITIONS OF STOCK OPTION GRANT 
 1. Grant of Option. The Company hereby grants to the Participant named in the Notice of Grant attached as Part I of this Award Agreement (the “Participant”) an option (the
“Option”) to purchase the number of Shares, as set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), subject to all of the terms and
conditions in this Award Agreement and the Plan, which is incorporated herein by reference. Subject to Section 18 of the Plan, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Award
Agreement, the terms and conditions of the Plan will prevail. 
 If designated in the Notice of Grant as an Incentive Stock
Option (“ISO”), this Option is intended to qualify as an ISO under Section 422 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). However, if this Option is intended to be an ISO,
to the extent that it exceeds the $100,000 rule of Code Section 422(d) it will be treated as a Nonstatutory Stock Option (“NSO”). Further, if for any reason this Option (or portion thereof) will not qualify as an ISO,
then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event will the Administrator, the Company or any Parent or Subsidiary or any of their respective employees or
directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 2. Vesting Schedule. Except as provided in Section 3, the Option awarded by this Award Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant. Shares
scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of the provisions of this Award Agreement, unless Participant will have been continuously a Service Provider from
the Date of Grant until the date such vesting occurs. Service Provider status will end on the last day Participant provides active service to the Company or Parent or Subsidiary and will not be extended by any notice of termination period that may
be required under applicable local law. 
 3. Administrator Discretion. The Administrator, in its discretion, may
accelerate the vesting of the balance, or some lesser portion of the balance, of the unvested Option at any time, subject to the terms of the Plan. If so accelerated, such Option will be considered as having vested as of the date specified by the
Administrator. 
 4. Exercise of Option. 
 (a) Right to Exercise. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this
Award Agreement. 
 (b) Method of Exercise. This Option is exercisable by delivery of an exercise notice, in the form
attached as Exhibit B (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which will state the election to exercise the

  
 -3-

 
Option, the number of Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required
by the Company pursuant to the provisions of the Plan. The Exercise Notice will be completed by Participant and delivered to the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares
together with any applicable tax withholding. This Option will be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by such aggregate Exercise Price. 

5. Method of Payment. Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the
election of Participant. 
 (a) cash (US dollars); or 
 (b) check (denominated in U.S. dollars); or 
 (c) consideration received by the
Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of
other Shares which have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares, provided that accepting such Shares, in the sole discretion of the Administrator, will not result in any adverse
accounting consequences to the Company. 
 6. Tax Obligations. 

(a) Withholding Taxes. Regardless of any action the Company or Participant’s employer (the “Employer”) takes with
respect to any or all Tax-Related Items, Participant acknowledges and agrees that the ultimate liability for all Tax-Related Items legally due by Participant is and remains Participant’s responsibility and may exceed the amount actually
withheld by the Company or the Employer. Participant further acknowledges that the Company and/or the Employer (a) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the
Option, including the grant, vesting, or exercise of the Option, the subsequent sale of Shares acquired under the Plan and the receipt of dividends, if any; and (b) does not commit to and is under no obligation to structure the terms of the
Option or any aspect of the Option to reduce or eliminate Participant’s liability for Tax-Related Items, or achieve any particular tax result. Further, if Participant has become subject to tax in more than one jurisdiction between the date of
grant and the date of any relevant taxable event, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

 No payment will be made to Participant (or his or her estate or beneficiary) for an Option unless and until satisfactory
arrangements (as determined by the Company) have been made by Participant with respect to the payment of any Tax-Related Items obligations of the Company and/or the Employer with respect to the Option. In this regard, Participant authorizes the
Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following: 

  
 -4-

 (i) withholding from Participant’s wages or other cash compensation paid to
Participant by the Company or the Employer; or 
 (ii) withholding from proceeds of the sale of Shares acquired upon exercise
of the Option, either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization); or 
 (iii) withholding in Shares to be issued upon exercise of the Option; or 
 (iv)
surrendering already-owned Shares having a Fair Market Value equal to the Tax-Related Items that have been held for such period of time to avoid adverse accounting consequences. 

If the obligation for Tax-Related Items is satisfied by withholding Shares, the Participant is deemed to have been issued the full number
of Shares purchased for tax purposes, notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-Related Items due as a result of the Participant’s participation in the Plan. Participant shall pay to the
Company or Employer any amount of Tax-Related Items that the Company may be required to withhold as a result of Participant’s participation in the Plan that cannot be satisfied by one or more of the means previously described in this paragraph
6. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to issue or deliver the Shares or the proceeds of the sale of Shares if Participant fails to comply with his or her obligations in connection with
the Tax-Related Items. 
 (b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Participant
herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Grant Date, or (ii) the date one (1) year after the
date of exercise, Participant will immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation income recognized by Participant.

 (c) Code Section 409A (Applicable Only to Participants Subject to U.S. Taxes). Under Code Section 409A, an
option that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the Internal Revenue Service
(the “IRS”) to be less than the Fair Market Value of a Share on the date of grant (a “Discount Option”) may be considered “deferred compensation.” A Discount Option may result in
(i) income recognition by Participant prior to the exercise of the option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The Discount Option may also result in
additional state income, penalty and interest charges to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share exercise price of this Option equals or exceeds the Fair
Market Value of a Share on the Date of Grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less than the Fair Market Value of a Share on the date of grant,
Participant will be solely responsible for Participant’s costs related to such a determination.

 7. Rights as Stockholder. Neither Participant nor any person claiming under or
through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on the records of the
Company or its transfer agents or registrars, and delivered to Participant. After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of
dividends and distributions on such Shares. 
 8. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE EMPLOYER AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THE OPTION OR ACQUIRING SHARES HEREUNDER.
PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AWARD AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER
FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE EMPLOYER TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE
(SUBJECT TO APPLICABLE LOCAL LAWS). 
 9. Nature of Grant. In accepting the Option, Participant acknowledges that:

 (a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended,
suspended or terminated by the Company at any time; 
 (b) the grant of the Option is voluntary and occasional and does not
Create any contractual or other right to receive future grants of Options, or benefits in lieu of Options even if Options have been granted repeatedly in the past; 
 (c) all decisions with respect to future awards of Options, if any, will be at the sole discretion of the Company; 
 (d) Participant’s participation in the Plan is voluntary; 
 (e) the Option
and the Shares subject to the Option are an extraordinary items that do not constitute regular compensation for services rendered to the Company or the Employer, and that are outside the scope of Participant’s employment contract, if any;

 (f) the Option and the Shares subject to the Option are not intended to replace any pension rights or compensation;

 (g) the Option and the Shares subject to the Option are not part of normal or expected compensation or salary for any
purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, or end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments and in no

  
 -6-

 
event should be considered as compensation for, or relating in any way to, past services for the Company or the Employer; 
 (h) the future value of the underlying Shares is unknown and cannot be predicted with certainty; further, if Participant exercises the Option and obtains Shares, the value of the Shares acquired upon
exercise may increase or decrease in value, even below the Exercise Price; 
 (i) Participant also understands that neither the
Company, nor any Affiliate is responsible for any foreign exchange fluctuation between local currency and the United States Dollar that may affect the value of the Option; 
 (j) in consideration of the grant of the Option, no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from termination of employment by the Employer (for
any reason whatsoever and whether or not in breach of local labor laws), and Participant irrevocably releases the Employer from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent
jurisdiction to have arisen, Participant shall be deemed irrevocably to have waived his or her entitlement to pursue such claim; and 
 (k) the Option and the benefits under the Plan, if any, will not automatically transfer to another company in the case of a merger, take-over or transfer of liability. 

10. No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any
recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant is hereby advised to consult with his or her own personal tax, legal and financial advisors
regarding Participant’s participation in the Plan before taking any action related to the Plan. 
 11. Data
Privacy. Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Agreement by and among, as applicable, the Company and
its Affiliates for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 
 Participant understands that the Company and its Affiliates may hold certain personal information about Participant, including, but not limited to, Participant’s name, home address and
telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of stock or directorships held in the Company or any Affiliate, details of all Options or any other entitlement to
shares of stock awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor, for the exclusive purpose of implementing, administering and managing the Plan (“Personal Data”). Participant understands that
Personal Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in the United States, Participant’s country (if different than the United
States), or elsewhere, and that the recipient’s country may have different data privacy laws and protections than Participant’s country.

Data as may be required to a broker or other third party with whom Participant may elect to deposit any Shares received upon exercise of the Option. Participant understands that Personal Data will be held only as long as is necessary to implement,
administer and manage Participant’s participation in the Plan. Participant understands that he or she may, at any time, view Personal Data, request additional information about the storage and processing of Personal Data, require any necessary

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT GRANT 
 1. Grant. The Company hereby grants to the individual named in the Notice of Grant attached as Part I of this Award Agreement (the “Participant”) under the Plan an Award of
Restricted Stock Units, subject to all of the terms and conditions in this Award Agreement and the Plan, which is incorporated herein by reference. Subject to Section 18 of the Plan, in the event of a conflict between the terms and conditions
of the Plan and the terms and conditions of this Award Agreement, the terms and conditions of the Plan will prevail. 
 2. Company’s Obligation to Pay. Each Restricted Stock Unit represents the right to receive a Share on the date it vests. Unless and until the Restricted Stock Units will have vested in the
manner set forth in Section 3, Participant will have no right to payment of any such Restricted Stock Units. Prior to actual payment of any vested Restricted Stock Units, such Restricted Stock Unit will represent an unsecured obligation of the
Company, payable (if at all) only from the general assets of the Company. Any Restricted Stock Units that vest in accordance with Sections 3 or 4 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in
whole Shares, subject to Participant satisfying any applicable tax withholding obligations as set forth in Section 7. Subject to the provisions of Section 4, such vested Restricted Stock Units will be paid in Shares as soon as practicable
after vesting, but in each such case within the period ending no later than the date that is two and one-half (2 1/2) months from the end of the Company’s tax year that includes the vesting date. 
 3. Vesting Schedule. Except as provided in Section 4, and subject to Section 5, the Restricted Stock Units awarded by this Award Agreement will vest in accordance with the vesting
provisions set forth in the Notice of Grant. Restricted Stock Units scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of the provisions of this Award Agreement,
unless Participant will have been continuously a Service Provider from the Date of Grant until the date such vesting occurs. 

4. Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser
portion of the balance, of the unvested Restricted Stock Units at any time, subject to the terms of the Plan. If so accelerated, such Restricted Stock Units will be considered as having vested as of the date specified by the Administrator.

 Notwithstanding anything in the Plan or this Award Agreement to the contrary, if the vesting of the balance, or some lesser
portion of the balance, of the Restricted Stock Units is accelerated in connection with Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of
Section 409A, as determined by the Company), other than due to death, and if (x) Participant is a “specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and
(y) the payment of such accelerated Restricted Stock Units will result in the imposition of additional tax under Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as a
Service Provider, then the payment of such accelerated Restricted Stock Units will not be made until the date six (6) months and one (1) day following the date of Participant’s termination as a Service Provider, unless the Participant
dies 

  
 -3-

 
following his or her termination as a Service Provider, in which case, the Restricted Stock Units will be paid in Shares to the Participant’s estate as soon as practicable following his or
her death. It is the intent of this Award Agreement to comply with the requirements of Section 409A so that none of the Restricted Stock Units provided under this Award Agreement or Shares issuable thereunder will be subject to the additional
tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. For purposes of this Award Agreement, “Section 409A” means Section 409A of the Code, and any proposed, temporary or final Treasury
Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time. 
 5. Forfeiture upon
Termination of Status as a Service Provider. Notwithstanding any contrary provision of this Award Agreement, the balance of the Restricted Stock Units that have not vested as of the time of Participant’s termination as a Service Provider
for any or no reason and Participant’s right to acquire any Shares hereunder will immediately terminate. 
 6. Death of
Participant. Any distribution or delivery to be made to Participant under this Award Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, or if no beneficiary survives Participant, the
administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the
transfer and compliance with any laws or regulations pertaining to said transfer. 
 7. Withholding of Taxes.
Notwithstanding any contrary provision of this Award Agreement, no certificate representing the Shares will be issued to Participant, unless and until satisfactory arrangements (as determined by the Administrator) will have been made by Participant
with respect to the payment of income, employment and other taxes which the Company determines must be withheld with respect to such Shares. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to
time, may permit Participant to satisfy such tax withholding obligation, in whole or in part (without limitation) by (a) paying cash, (b) electing to have the Company withhold otherwise deliverable Shares having a Fair Market Value equal
to the minimum amount required to be withheld, (c) delivering to the Company already vested and owned Shares having a Fair Market Value equal to the amount required to be withheld, or (d) selling a sufficient number of such Shares
otherwise deliverable to Participant through such means as the Company may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld. To the extent determined appropriate by the Company in
its discretion, it will have the right (but not the obligation) to satisfy any tax withholding obligations by reducing the number of Shares otherwise deliverable to Participant. If Participant fails to make satisfactory arrangements for the payment
of any required tax withholding obligations hereunder at the time any applicable Restricted Stock Units otherwise are scheduled to vest pursuant to Sections 3 or 4, Participant will permanently forfeit such Restricted Stock Units and any right to
receive Shares thereunder and the Restricted Stock Units will be returned to the Company at no cost to the Company. 
 8.
Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until
certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, 

  
 -4-

 
and delivered to Participant. After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of
dividends and distributions on such Shares. 
 9. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES
THAT THE VESTING OF THE RESTRICTED STOCK UNITS PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE
ACT OF BEING HIRED, BEING GRANTED THIS AWARD OF RESTRICTED STOCK UNITS OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AWARD AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH
HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR
THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 10. Address for Notices. Any notice to be given to the Company under the terms of this Award Agreement will be addressed to the Company, in care of its General Counsel at Fulcrum BioEnergy, Inc.,
4900 Hopyard Road, Suite 220, Pleasanton, CA 94588 or at such other address as the Company may hereafter designate in writing. 

11. Grant is Not Transferable. Except to the limited extent provided in Section 6, this grant and the rights and privileges
conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign,
pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately
will become null and void. 
 12. Binding Agreement. Subject to the limitation on the transferability of this grant
contained herein, this Award Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 

13. Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing,
registration or qualification of the Shares upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to
Participant (or his or her estate), such issuance will not occur unless and until such listing, registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company. Where the
Company determines that the delivery of the payment of any Shares will violate federal securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates

  
 -5-

 
that the delivery of Shares will no longer cause such violation. The Company will make all reasonable efforts to meet the requirements of any such state or federal law or securities exchange and
to obtain any such consent or approval of any such governmental authority. 
 14. Plan Governs. This Award Agreement is
subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Award Agreement and one or more provisions of the Plan, the provisions of the Plan will govern. Capitalized terms used and not defined
in this Award Agreement will have the meaning set forth in the Plan. 
 15. Administrator Authority. The Administrator
