8.3 The Company’s Right of First Refusal. In the event the Participant proposes to sell, pledge or otherwise transfer to a third party any Owned Shares acquired under the Plan, or any interest in such Shares, the Company shall have the “Right of First Refusal” with respect to all of such Shares. If the Participant wishes to transfer Owned Shares acquired under the Plan, he or she must give written notice (“Transfer Notice”) to the Company describing fully the proposed transfer, including the number of Shares proposed to be transferred, the proposed transfer price and the name and address of the proposed transferee. The Transfer Notice shall be signed both by the Participant and by the proposed transferee and must constitute a binding commitment of both parties to the transfer of the Shares, subject to the Company’s Right of First Refusal.

The Company and its assignees shall have the right (but not the obligation) to purchase any or all of the Shares on the terms described in the Transfer Notice (subject, however, to any change in such terms permitted in the next paragraph) by delivery of a Notice of Exercise of the Right of First Refusal within 30 days after the date that the Company receives the Transfer Notice. The Company’s rights with respect to the Right of First Refusal shall be freely assignable, in whole or in part.

If the Company (or its assignee) fails to exercise its Right of First Refusal within 30 days after the date that it received the Transfer Notice, the Participant may, not later than six months following the date the Company receives the Transfer Notice, conclude a transfer of the Shares

-10-

subject to the Transfer Notice on the terms and conditions described in the Transfer Notice; provided that the transferee acknowledges in writing that such transferee remains bound by this Right of First Refusal with respect to any subsequent transfer of such Shares, as described in the last paragraph of this Section 8.3. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as well as any subsequent proposed transfer by the Participant, shall again be subject to the Right of First Refusal and shall require compliance with the procedure described in this Section. If the Company (or its assignee) exercises its Right of First Refusal, the Participant and the Company (or its assignee) shall consummate the sale of the Shares on the terms set forth in the Transfer Notice.

The Company’s Right of First Refusal shall inure to the benefit of its successors and assigns and shall be binding upon any transferee of the Shares.

The Company’s Right of First Refusal shall terminate upon the Company’s initial Public Offering.

8.4 Delivery of Owned Shares to the Company. Within ten (10) days after the Company’s exercise of its Repurchase Right or its Right of First Refusal, as the case may be, the Participant (or the Participant’s guardian, legal representative or Designated Beneficiary) shall deliver to the Company all certificates representing the Participant’s Owned Shares with appropriate executed stock transfers conveying, representing and warranting good title to the Company for the Participant’s Owned Shares in compliance with the terms of the Plan and free and clear of all liens, encumbrances or claims of any third party.

8.5 Payment of Purchase Price to Participant.

Upon a Change in Control, the Participant shall be given an opportunity to exercise any vested and unexercised Option prior to the consummation of the Change in Control and participate in such transaction as a holder of Common Stock. The Company shall have the discretion to provide for the termination of any outstanding Option as of the effective date of the Change in Control; provided that, the Option will not be so terminated (without the consent of the Participant) before the expiration of ten (10) days following the date on which the Company provided written notice of the Change in Control. If the Change in Control is structured as a (i) merger or consolidation, the Participant will waive any dissenters rights, appraisal rights or similar rights in connection with such merger or consolidation, or (ii) sale of Shares, the Participant will agree to sell all of his Owned Shares and any vested Option on the terms and conditions approved by the Company and comparable to the terms applicable (including, without limitation, the execution of documents) to the Company’s other holders of Common Stock. The Participant will take all actions that the Company considers necessary or desirable in connection with the consummation of the Change in Control.

8.7 Company’s Drag-Along Rights. Upon a Change in Control, the Company will have the right (the “Drag-Along Right”), but not the obligation, to cause the Participant to

-11-

tender for purchase any or all Owned Shares, in the same proportion, for the same consideration, at the same price and on the same terms and conditions as apply to the Company’s other holders of Common Stock. The Drag-Along Right shall apply to the Participant’s Owned Shares. If the Company elects to exercise the Drag-Along Right, it will notify the Participant in writing (the “Drag-Along Notice”). Such Drag-Along Notice will set forth the name and address of the proposed purchaser, the proposed amount and form of consideration and other terms and conditions of transfer offered by the proposed purchaser, the number of Owned Shares proposed to be purchased by such purchaser, and a calculation of the purchase price applicable to the Participant. Upon the receipt of a Drag-Along Notice, the Participant will be obligated to transfer its Owned Shares free and clear of any encumbrances to the proposed purchaser on the terms and for the price set forth in the Drag-Along Notice. The Company’s Drag-Along Right shall terminate upon the Company’s initial Public Offering.

8.8 Legend. Each certificate evidencing Owned Shares and each certificate issued in exchange for or upon the transfer of any Owned Shares before a Public Offering will be stamped or otherwise imprinted with such legend as the Company requires (including, without limitation, legends noting the restrictions contained in this Section 8).

8.9 Disqualifying Disposition. The Participant must notify the Company of any disposition of any Shares issued pursuant to the exercise of an ISO under the circumstances described in Code Section 421(b) (relating to certain disqualifying dispositions) (any such circumstance, a “Disqualifying Disposition”), within 10 days of such Disqualifying Disposition.

9. Beneficiary Designation

Each Participant may, from time to time, name any Designated Beneficiary (who may be named contingently or successively) to whom any benefit under the Plan is to be paid in case the Participant should die before receiving any or all of his or her Plan benefits. Each beneficiary designation will revoke all prior designations by the same Participant, must be in a form prescribed by the Company, and must be made during the Participant’s lifetime. If a Designated Beneficiary predeceases the Participant or no beneficiary has been designated, benefits remaining unpaid at the Participant’s death will be paid to the Participant’s estate or other entity described in the Participant’s Award Agreement.

10. Rights of Participants

(e) A Participant may make a deferral election in other circumstances and at such times as may be permitted under Section 409A of the Code.

11.3 Distribution Dates. Any deferred compensation arrangement created under the Plan shall be distributed at such times as provided in the Award Agreement or a separate election form, which may include the earliest or latest of one or more of the following:

(g) such other events as permitted under Section 409A and the regulations and guidance thereunder.

11.4 Restrictions on Distributions. No distribution of a deferral may be made pursuant to the Plan if the Committee reasonably determines that such distribution would (i) violate federal securities laws or other applicable law; (ii) be nondeductible pursuant to Code Section 162(m); or (iii) jeopardize the Company’s ability to continue as a going concern. In any such case, distribution shall be made at the earliest date at which the Committee determines such distribution would not trigger clause (i), (ii) or (iii) above.

11.5 Redeferrals. The Company, in its discretion, may permit an Employee to make a subsequent election to delay a distribution date, or, as applicable, to change the form distribution payments, attributable to one or more events triggering a distribution, so long as (i) such election may not take effect until at least 12 months after the election is made, (ii) such election defers the distribution for a period of not less than five years from the date such distribution would otherwise have been made, and (iii) such election may not be made less than 12 months prior to the date the distribution was to be made.

11.6 Termination of Deferred Compensation Arrangements. In addition, the Committee may in its discretion terminate the deferred compensation arrangements created under the Plan subject to the following:

(a) the arrangement may be terminated within the 30 days preceding, or 12 months following, a change in control, as defined in Section 409A, provided that all payments under such arrangement are distributed in full within 12 months after termination;

(b) the arrangement may be terminated in the Committee’s discretion at any time provided that (i) all deferred compensation arrangements of similar type maintained by the Company are terminated, (ii) all payments are made at least 12 months and no more than 24 months after the termination, and (iii) the Company does not adopt a new arrangement of similar type for a period of five years following the termination of the arrangement; and

(c) the arrangement may be terminated within 12 months of a corporate dissolution taxed under Code Section 331 or with the approval of a bankruptcy court pursuant to 11 U.S.C. 503(b)(1)(A) provided that the payments under the arrangement are distributed by the latest of the (i) the end of the calendar year of the termination, (ii) the calendar year in which such payments are fully vested, or (iii) the first calendar year in which such payment is administratively practicable.

-14-

11.7 Interpretation and Section 409A Payments. Any Award under the Plan is intended either (i) to be exempt from Section 409A under the stock right, short-term deferral or other exceptions available under Section 409A, or (ii) to comply with Section 409A, and shall be administered in a manner consistent with such intent. For purposes of Section 409A, each payment of deferred compensation under this Plan shall be considered a separate payment.

12. Amendment, Modification and Termination

12.1 Amendment, Modification and Termination. The Board may at any time and from time to time, alter, amend, modify or terminate the Plan in whole or in part. Subject to the terms and conditions of the Plan, the Board may modify, extend or renew outstanding Awards under the Plan, or accept the surrender of outstanding Awards (to the extent not already exercised) and grant new Awards in substitution of them (to the extent not already exercised). The Board will not, however, modify any outstanding Incentive Stock Option to specify a lower Exercise Price. Notwithstanding the foregoing, no modification of an Award will, without the prior written consent of the Participant, materially impair any rights or obligations under any Award already granted under the Plan.

12.2 Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. In recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4.3) affecting the Company or its financial statements, or in recognition of changes in applicable laws, regulations, or accounting principles, and, whenever the Board determines that adjustments are appropriate to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, the Board may, using reasonable care, adjust the terms and conditions of, and the criteria included in, Awards. Notwithstanding the foregoing, no modification of an Award will, without the prior written consent of the Participant, materially impair any rights or obligations under any Award already granted under the Plan.

13. Withholding

13.1 Tax Withholding. The Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount (either in cash or Shares) sufficient to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising under this Plan.

13.2 Share Withholding. With respect to withholding required upon the exercise of Options, upon the lapse of restrictions on Restricted Stock, or upon any other taxable event arising as a result of Awards granted hereunder, the Company may satisfy the minimum withholding requirement for supplemental wages, in whole or in part, by withholding Shares having a Fair Market Value (determined on the date the Participant recognizes taxable income on the Award) equal to the minimum amount of withholding tax required to be collected on the transaction. The Participant may elect, subject to the approval of the Board, to deliver the necessary funds to satisfy the withholding obligation to the Company, in which case there will be no reduction in the Shares otherwise distributable to the Participant.

-15-

14. Successors

All obligations of the Company under the Plan or any Award Agreement will be binding on any successor to the Company resulting from a Change in Control.

15. Legal Construction

15.1 Number. Except where otherwise indicated by the context, any plural term used in this Plan includes the singular and a singular term includes the plural.

15.2 Severability. If any provision of the Plan is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provision had not been included.

15.3 Requirements of Law. The granting of Awards and the issuance of Share and/or cash payouts under the Plan will be subject to all applicable laws, rules, and regulations (including, without limitation, Section 25102(o) of the California Corporations Code) and to any approvals by governmental agencies or national securities exchanges as may be required.

15.4 Securities Law Compliance. As to any individual who is, on the relevant date, an officer, director or ten percent beneficial owner of any class of the Company’s equity securities that is registered pursuant to Section 12 of the Exchange Act, all as defined under Section 16 of the Exchange Act, transactions under this Plan are intended to comply with all applicable conditions of Rule 16b-3 under the Exchange Act, or any successor rule. To the extent any provision of the Plan or action by the Board fails to so comply, it will be deemed null and void, to the extent permitted by law and deemed advisable by the Board.

15.5 Unfunded Status of the Plan. The Plan is intended to constitute an “unfunded” plan for incentive and deferred compensation. With respect to any payments or deliveries of Shares not yet made to a Participant by the Company, the Participant’s rights are no greater than those of a general creditor of the Company. The Board may authorize the establishment of trusts or other arrangements to meet the obligations created under the Plan, so long as the arrangement does not cause the Plan to lose its legal status as an unfunded plan.

15.6 Non-U.S. Based Person. Notwithstanding any other provision of the Plan to the contrary, the Board may make Awards to Persons who are not citizens or residents of the United States on such terms and conditions different from those specified in the Plan as may, in the Board’s judgment, be necessary or desirable to foster and promote achievement of the Plan’s purposes. In furtherance of such purposes, the Board may make such modifications, amendments, procedures and subplans as may be necessary or advisable to comply with provisions of laws in other countries or jurisdictions in which the Company operates or has employees.

15.7 Other Benefits. No Award granted under the Plan shall be considered compensation for purposes of computing benefits under any Retirement plan of the Company or an Affiliate, nor affect any benefits or compensation under any other benefit or compensation plan of the Company or an Affiliate, now or subsequently in effect.

-16-

15.8 Compliance With Code Section 409A. Any provision of the Plan that becomes subject to Code Section 409A, will be interpreted and applied consistent with that Section and the applicable Treasury Regulations.

15.9 Governing Law. To the extent not preempted by federal law, the Plan and all agreements hereunder will be construed and enforced in accordance with, and governed by, the laws of the State of California, without giving effect to its conflict of laws principles. Participants, the Company, and Affiliates each submit and consent to the jurisdiction of the courts in the State of California, County of San Francisco, including the Federal Courts located therein, should Federal jurisdiction requirements exist in any action brought to enforce (or otherwise relating to) this Plan or an Award Agreement.

INCENTIVE STOCK OPTION AGREEMENT

UNDER

SUNRUN INC. 2008 EQUITY INCENTIVE PLAN

This INCENTIVE STOCK OPTION AGREEMENT (“Agreement”) is between Sunrun Inc. (the “Company”) and Participant (“Participant” or “Optionholder”), and is dated effective as of the date approved by the Company’s Board of Directors (the “Grant Date”). Any term capitalized but not defined in this Agreement will have the meaning set forth in the Sunrun Inc. 2008 Equity Incentive Plan (the “Plan”).

1. Option Grant. In accordance with the terms of the Plan, and subject to the terms and conditions of this Agreement, the Company hereby grants to Participant an option to purchase Shares of the Company’s Common Stock (the “Option”) as set forth in the Notice of Stock Option Grant (the “Notice”). Participant may exercise this Option only after it has become vested in accordance with Section 4.

This Option is intended to be an Incentive Stock Option within the meaning of Code Section 422 and the Plan. To the extent all or part of this Option would cause the aggregate Fair Market Value of Common Stock with respect to which Incentive Stock Options are exercisable by Participant for the first time during a calendar year (under all plans of the Company and its Affiliates) to exceed $100,000, that portion of this Option shall be deemed a nonqualified stock option.

2. Exercise Price. The Exercise Price will be as set forth in the Notice, and no less than the Fair Market Value of a Share on the Grant Date.

3. Payment of Exercise Price. Participant must pay the Exercise Price in United States dollars, in cash or by personal check payable to the order of the Company, at the time of purchase. Alternatively, Participant may pay the Exercise Price, or any part of it, with: (i) Shares owned by Participant with a Fair Market Value equal to the Exercise Price being duly endorsed for transfer to the Company free and clear of any encumbrance; or (ii) any combination of cash, personal check and Shares meeting the requirements of clause (i) above.

(a) If the Company has a withholding obligation upon Participant’s exercise of the Option, Participant must satisfy this obligation by paying the amount of required withholding to the Company. If Participant does not pay the amount of required withholding to the Company, the Company will withhold from the Shares delivered or from other amounts payable to Participant, the minimum amount of funds required to cover all applicable federal, state and local income and employment taxes required to be withheld by the Company by reason of such exercise of the Option.

(b) Shares used to satisfy the Exercise Price and/or any minimum required withholding tax will be valued at their Fair Market Value as determined by the Board as of the date of exercise.

(c) The Company will issue no Shares pursuant to the Option before Participant has: (i) paid the Exercise Price and, if applicable, the withholding obligation, in full and (ii) satisfied all conditions and/or restrictions applicable to the Options or Shares.

4. Term, Vesting and Exercise of the Option.

(a) The Option will expire ten (10) years from the Grant Date (the “Expiration Date”).

(b) Twenty-five percent (25%) of the Shares subject to the Option, rounded down to the next whole number, will vest on the first anniversary of the Vesting Commencement Date (“Vesting Commencement Date”) as set forth in the Notice, provided Participant has remained in continuous Service until that date, and 1/36th of the remaining Shares subject to the Option, rounded down to the next whole number, will vest on the same day of the month as the Vesting Commencement Date each month thereafter (or if there is no corresponding day, on the last day of the month), during Participant’s continuous Service so that all of the Shares subject to the Option will be fully vested on the fourth anniversary of the Vesting Commencement Date.

(c) Notwithstanding any other provision of this Agreement, Participant will forfeit his or her right to exercise the Option, whether or not it has already vested, if the Board determines in its sole discretion that Participant has been discharged from Service for Cause.

(d) After the Option has vested, and while it is exercisable, Participant (or, in the event of Participant’s death, Participant’s estate) may exercise the Option in whole or in part by written notice to the Company indicating the number of Shares being purchased. Participant (or, in the event of Participant’s death, Participant’s estate) must sign the notice. Full payment of the Exercise Price must accompany the notice plus, if applicable, any required withholding tax. Notwithstanding the foregoing, the Option may not be exercised for fewer than 100 Shares at any one time or, if fewer than 100 Shares remain, all the then-remaining Shares. An Option must be exercised as to a whole number of Shares.

5. Termination of Service. After termination of Service, Participant’s right to exercise the Option will be subject to the following rules.

(a) Disability or Death. If Participant terminates Service through Disability or death, Participant (or in the case of his or her death, Participant’s estate) may exercise the Option within the six month period following the termination.

(b) Voluntary Termination. If Participant voluntarily terminates Service for any reason other than Disability or death, Participant (i) may, within the thirty day period following the effective date of termination, exercise the Option to the extent that it was vested and exercisable on such date and (ii) will forfeit the Option to the extent that it was not vested and exercisable on such date.

-2-

(c) Involuntary Termination. If the Company terminates Participant’s Service other than for Disability, death or Cause, Participant (or, in the case of his or her subsequent death, Participant’s estate): (i) may, within the thirty day period following the effective date of termination, exercise the Option to the extent that it was vested and exercisable on such date and (ii) will forfeit the Option to the extent that it was not vested and exercisable on such date.

In no event may the Option be exercised after the Expiration Date.

6. Transferability of Option and Shares Acquired Upon Exercise of Option. Except as permitted by Rule 701 of the Security Act of 1933, by will or by the laws of descent and distribution, Participant may not sell, transfer, pledge, assign or otherwise alienate or hypothecate the Option or any Owned Shares. If Participant sells, transfers, pledges, assigns or otherwise alienates or hypothecates the Option or Owned Shares in breach of this Section, the Company will not be required to transfer the Option or Owned Shares on its books or to treat any such transferee as owner of the Option or Owned Shares.

(a) If Participant disposes of Owned Shares acquired upon exercise of this Option within two years from the Grant Date or within one year after his or her exercise of this Option, such disposition will disqualify this Option from being treated as an incentive stock option under Code Section 422 and the Plan.

(b) Participant represents and warrants to the Company that he or she will notify the Company in writing no later than 10 calendar days following any sale of Owned Shares acquired upon exercise of the Option.

7. Company’s Right of First Refusal and Drag-Along Right. Under the terms of the Plan, the Company has the right upon receipt of a Transfer Notice to exercise its Right of First Refusal and purchase from Participant all of the Owned Shares described in the Transfer Notice. Upon a Change in Control, the Company has the right to cause Participant to tender any and all Owned Shares for purchase. Participant hereby agrees to be bound by all provisions of the Plan including without limitation the Right of First Refusal and Drag-Along Right in Section 8 thereof.

8. Participant’s Right to Financial Information. If required by law, each year the Company will furnish to Participant, its annual balance sheet and income statement, unless such Participant is a key employee whose duties with the Company assure his/her access to equivalent information. Such balance sheet and income statement need not be audited and shall be treated as confidential by Participant.

9. Securities Law Requirements. If at any time the Board determines that exercising the Option or issuing Shares would violate applicable securities laws, the Option will not be exercisable, and the Company will not be required to issue Shares. The Board may declare any provision of this Agreement or action of its own null and void, if it determines the provision or action fails to comply with applicable securities laws. As a condition to exercise, the Company may require Participant to make written representations it deems necessary or desirable to comply with applicable securities laws.

-3-

10. Representations and Warranties. Participant represents and warrants to the Company that Participant has received a copy of the Plan and this Agreement, has read and understands the terms of the Plan and this Agreement, and agrees to be bound by their terms and conditions in all respects.

11. Market Stand-Off. Participant, if required by the Company and the managing underwriter of the Company’s initial registered public offering of Common Stock, shall agree not to offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, make any short sale of, loan, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any Shares acquired under this Agreement or other securities of the Company held by such holder or enter into any swap or similar agreement that transfers, in whole or in part, the economic risk of ownership of any such securities, whether any such transaction is to be settled by the delivery of any Shares acquired under this Agreement or other securities of the Company, in cash or otherwise, during a period not to exceed one hundred eighty (180) days following the effective date of the first registration statement of the Company filed under the Securities Act. Such agreement shall be in writing in a form reasonably satisfactory to the Company, the majority holders in interest of the Company’s Series A investors and such managing underwriter. The Company shall use its best efforts to ensure that such agreement (i) provides for periodic early releases of portions of the securities subject thereto upon the occurrence of certain specified events, and (ii) provides that in the event of an early release, all such holders will be released on a pro-rata basis from such market stand-off agreements. The obligations described in this Section 11 shall not apply to (i) a registration relating solely to employee benefit plans on Form S-8 or a similar form that may be promulgated in the future, (ii) a registration relating solely to a transaction under Rule 145 of the Securities Act on Form S-4 or a similar form that may be promulgated in the future, or (iii) transfers pursuant to an effective registration statement under the Securities Act in compliance with Rule 144 or pursuant to an effective exemption from registration under the Securities Act and any applicable state securities laws, if the transferee shall agree in writing to be bound by such market stand-off. The Company may impose a stop-transfer instruction with respect to the shares (or other securities) subject to the foregoing restriction until the end of such one hundred eighty day (180) period. The Market Stand-Off limitation of this Section 11 shall also apply to any new, substituted, or additional securities, which are distributed with respect to any Shares subject to this Option as a result of a stock dividend, spin-off, stock split or similar transaction affecting the Company’s outstanding securities without receipt of consideration. The Company’s underwriters shall be beneficiaries of the agreement set forth in this Section 11.

12. No Obligation to Exercise Option. Neither Participant nor his or her transferee is or will be obligated by the grant of the Option to exercise it.

13. No Limitation on Rights of the Company. The grant of the Option does not and will not in any way affect the right or power of the Company to make adjustments, reclassifications or changes in its capital or business structure, or to merge, consolidate, dissolve, liquidate, sell or transfer all or any part of its business or assets.

14. Plan and Agreement Not a Contract of Employment or Service. Neither the Plan nor this Agreement is a contract of employment or Service, and no terms of Participant’s employment or

-4-

Service will be affected in any way by the Plan, this Agreement or related instruments, except to the extent specifically expressed therein. Neither the Plan nor this Agreement will be construed as conferring any legal rights of Participant to continue to be employed or remain in Service, nor will it interfere with any Company right to discharge Participant or to deal with Participant regardless of the existence of the Plan, this Agreement or the Option.

15. Participant to Have No Rights as a Stockholder. Before the date as of which Participant is recorded on the books of the Company as the holder of any Shares underlying the Option, Participant will have no rights as a stockholder with respect to such Shares.

16. Notice. Any notice or other communication required or permitted under this Agreement must be in writing and must be delivered personally, sent by certified, registered or express mail, or sent by overnight courier, at the sender’s expense. Notice will be deemed given when delivered personally or, if mailed, three days after the date of deposit in the United States mail or, if sent by overnight courier, on the regular business day following the date sent. Notice to the Company should be sent to Sunrun Inc., 45 Fremont Street, 32nd Floor, San Francisco, CA 94105, Attention: Chief Executive Officer. Notice to Participant should be sent to the address set forth on the signature page below. Either party may change the Person and/or address to whom the other party must give notice under this Section 16 by giving the other party written notice of such change, in accordance with the procedures described above.

17. Special Rules if Participant is a Ten Percent Owner. Notwithstanding any other provision of this Agreement to the contrary, if Participant is a Ten Percent Owner of the Company, then the portion of this Option that is an incentive stock option will expire upon the earlier of (i) the Expiration Date, or (ii) the fifth anniversary of the Grant Date.

18. Successors. All obligations of the Company under this Agreement will be binding on and inure to the benefit of any assignee of or any successor to the Company, whether the existence of the successor results from a Change in Control or otherwise.

19. Governing Law. To the extent not preempted by federal law, this Agreement will be construed and enforced in accordance with, and governed by, the laws of the State of California, without giving effect to its conflict of laws principles.

20. Plan Document Controls. The rights granted under this Agreement are in all respects subject to the provisions set forth in the Plan to the same extent and with the same effect as if set forth fully in this Agreement. If the terms of this Agreement conflict with the terms of the Plan document, the Plan document will control.

21. Amendment of the Agreement. The Company and Participant may amend this Agreement only by a written instrument signed by both parties.
