an Award in order to satisfy the exercise or purchase price for such Award or any withholding taxes due with respect to such Award shall be treated as not issued and shall continue to be available under the Plan. Shares issued under the Plan and
later repurchased by the Company pursuant to any repurchase right that the Company may have shall not be available for future grant under the Plan. 
 4. Administration of the Plan. 
 (a) General. The Plan

Plan to Employees and Consultants (who are not subject to Section 16 of the Exchange Act) within parameters specified by the Board.

directed by the Board. From time to time the Board may increase the size of any Committee and appoint additional members thereof, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies (however
caused) and dissolve a Committee and thereafter directly administer the Plan, all to the extent permitted by the Applicable Laws and, in the case of a Committee administering the Plan in accordance with the requirements of Rule 16b-3 or
Section 162(m) of the Code, to the extent permitted or required by such provisions.

whom Awards may from time to time be granted; 
 (iii) to determine the number of Shares to be covered by each Award;

 (iv) to approve the form(s) of agreement(s) and other related documents used under the Plan;

conditions include but are not limited to the exercise or purchase price, the time or times when Awards may be exercised (which may be based on performance criteria), the circumstances (if any) when vesting will be accelerated or forfeiture
restrictions will be waived, and any restriction or limitation regarding any Award, Optioned Stock, or Restricted Stock; 

(vi) to amend any outstanding Award or agreement related to any Optioned Stock or Restricted Stock, including any amendment adjusting
vesting (e.g., in connection with a change in the terms or conditions under which such person is providing services to the Company), provided that no amendment shall be made that would materially and adversely affect the rights of any Participant
without his or her consent;

Section 10(c) instead of Common Stock; 

  
 -6-









 (viii) to implement an Option Exchange Program and establish the terms and conditions of
such Option Exchange Program, provided that no amendment or adjustment to an Option that would materially and adversely affect the rights of any Optionee shall be made without his or her consent; 

(ix) to grant Awards to, or to modify the terms of any outstanding Option Agreement or Restricted Stock Purchase Agreement or any
agreement related to any Optioned Stock or Restricted Stock held by, Participants who are foreign nationals or employed outside of the United States with such terms and conditions as the Administrator deems necessary or appropriate to accommodate
differences in local law, tax policy or custom which deviate from the terms and conditions set forth in this Plan to the extent necessary or appropriate to accommodate such differences; and 

(x) to construe and interpret the terms of the Plan, any Option Agreement or Restricted Stock Purchase Agreement, and any agreement
related to any Optioned Stock or Restricted Stock, which constructions, interpretations and decisions shall be final and binding on all Participants. 
 (d) Indemnification. To the maximum extent permitted by Applicable Laws, each member of the Committee (including officers of the Company, if applicable), or of the Board, as applicable,
shall be indemnified and held harmless by the Company against and from (i) any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or
proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or pursuant to the terms and conditions of any Award except for actions taken in bad faith or failures
to act in bad faith, and (ii) any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or
her, provided that such member shall give the Company an opportunity, at its own expense, to handle and defend any such claim, action, suit or proceeding before he or she undertakes to handle and defend it on his or her own behalf. The foregoing
right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Articles of Incorporation, Certificate of Incorporation or Bylaws, by contract, as a matter of law,
or otherwise, or under any other power that the Company may have to indemnify or hold harmless each such person.

Nonstatutory Stock Option. 

  
 -7-

Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock Options shall be taken into account in the order in which they were
granted, and the Fair Market Value of the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option. 
 (d) No Employment Rights. Neither the Plan nor any Award shall confer upon any Employee or Consultant any right with respect to continuation of an employment or consulting
relationship with the Company (any Parent or Subsidiary), nor shall it interfere in any way with such Employee’s or Consultant’s right or the Company’s (Parent’s or Subsidiary’s) right to terminate his or her employment or
consulting relationship at any time, with or without cause. 
 6. Term of Plan. The Plan shall become effective
upon its adoption by the Board of Directors. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 16 below. 
 7. Term of Option. The term of each Option shall be the term stated in the Option Agreement; provided that the term shall be no more than ten (10) years from the date of grant thereof
or such shorter term as may be provided in the Option Agreement and provided further that, in the case of an Incentive Stock Option granted to a person who at the time of such grant is a Ten Percent Holder, the term of the Option shall be five
(5) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 
 8.
Limitation on Grants to Participants. On and after such time, if any, as the Common Stock becomes a Listed Security and subject to adjustment as provided in Section 14 below, the maximum aggregate number of Shares that may be
subject to Awards granted to any one person under this Plan for any fiscal year of the Company shall be 500,000 Shares, provided that such limitation shall be 500,000 Shares during the fiscal year of any person’s initial year of service with
the Company. 
 9. Option Exercise Price and Consideration. 

(a) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option shall be
such price as is determined by the Administrator and set forth in the Option Agreement, but shall be subject to the following: 

(i) In the case of an Incentive Stock Option 
 (A) granted to an Employee who at the time of grant is a Ten Percent Holder, the per Share exercise price shall be no less than 110% of the Fair Market Value on the date of grant; 

  
 -8-









 (B) granted to any other Employee, the per Share exercise price shall be no less than 100%
of the Fair Market Value on the date of grant; 
 (ii) Except as provided in subsection (iii) below, in the case of a
Nonstatutory Stock Option the per Share exercise price shall be such price as is determined by the Administrator, provided that, if the per Share exercise price is less than 100% of the Fair Market Value on the date of grant, it shall otherwise
comply with all Applicable Laws, including Section 409A of the Code; 
 (iii) In the case of a Nonstatutory Stock Option
that is intended to qualify as performance-based compensation under Section 162(m) of the Code and is granted on or after the date, if ever, on which the Common Stock becomes a Listed Security, the per Share exercise price shall be no less than
100% of the Fair Market Value on the date of grant; and 
 (iv) Notwithstanding the foregoing, Options may be granted with a
per Share exercise price other than as required above pursuant to a merger or other corporate transaction. 
 (b)
Permissible Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option
and to the extent required by Applicable Laws, shall be determined at the time of grant) and may consist entirely of (1) cash; (2) check; (3) to the extent permitted under Applicable Laws, delivery of a promissory note with such
recourse, interest, security and redemption provisions as the Administrator determines to be appropriate (subject to the provisions of Section 153 of the Delaware General Corporation Law); (4) cancellation of indebtedness; other previously
owned Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option is exercised; a Cashless Exercise; (7) such other consideration and method of payment permitted under
Applicable Laws; or (8) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected
to benefit the Company and the Administrator may, in its sole discretion, refuse to accept a particular form of consideration at the time of any Option exercise. 
 10. Exercise of Option. 
 (a) General.

 (i) Exercisability. Any Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, consistent with the terms of the Plan and reflected in the Option Agreement, including vesting requirements and/or performance criteria with respect to the Company, and Parent or Subsidiary, and/or the
Optionee. 
 (ii) Leave of Absence. The Administrator shall have the discretion to determine whether and to what
extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such unpaid leave (unless otherwise required by the
Applicable Laws). 

  
 -9-









 
Notwithstanding the foregoing, in the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon a Optionee’s returning from military leave
(under conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have
applied had the Optionee continued to provide services to the Company (or any Parent or Subsidiary, if applicable) throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 

(iii) Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The Administrator
may require that an Option be exercised as to a minimum number of Shares, provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then exercisable. 

(iv) Procedures for and Results of Exercise. An Option shall be deemed exercised when written notice of such
exercise has been received by the Company in accordance with the terms of the Option Agreement by the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to which the Option is exercised and
has paid, or made arrangements to satisfy, any applicable withholding requirements in accordance with Section 12 below. The exercise of an Option shall result in a decrease in the number of Shares that thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (v)
Rights as Holder of Capital Stock. Until the issuance of the Shares (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 holder of capital stock shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock
certificate is issued, except as provided in Section 14 below. 
 (b) Termination of Employment or Consulting
Relationship. The Administrator shall establish and set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain exercisable, if at all, following termination of an Optionee’s Continuous
Service Status, which provisions may be waived or modified by the Administrator at any time. To the extent that an Option Agreement does not specify the terms and conditions upon which an Option shall terminate upon termination of an Optionee’s
Continuous Service Status, the following provisions shall apply: 
 (i) General Provisions. If the Optionee (or
other person entitled to exercise the Option) does not exercise the Option to the extent so entitled within the time specified below, the Option shall terminate and the Optioned Stock underlying the unexercised portion of the Option shall revert to
the Plan. In no event may any Option be exercised after the expiration of the Option term as set forth in the Option Agreement (and subject to Section 7). 
 (ii) Termination other than Upon Disability or Death or for Cause. In the event of termination of an Optionee’s Continuous Service Status other than under the circumstances set forth in
subsections (iii) through (v) below, such Optionee may exercise any outstanding Option at any time within three (3) months following such termination to the extent the Optionee is vested in the Optioned Stock. 

  
 -10-









 (iii) Disability of Optionee. In the event of termination of an
Optionee’s Continuous Service Status as a result of his or her Disability, such Optionee may exercise any outstanding Option at any time within six (6) months following such termination to the extent the Optionee is vested in the Optioned
Stock. 
 (iv) Death of Optionee. In the event of the death of an Optionee during the period of Continuous
Service Status since the date of grant of any outstanding Option, or within three (3) months following termination of Optionee’s Continuous Service Status, the Option may be exercised by the Optionee’s estate, or by a person who
acquired the right to exercise the Option by bequest or inheritance, at any time within six (6) months following the date of death or, if earlier, the date the Optionee’s Continuous Service Status terminated, but only to the extent the
Optionee is vested in the Optioned Stock. 
 (v) Termination for Cause. In the event of termination of an
Optionee’s Continuous Service Status for Cause, any outstanding Option (including any vested portion thereof) held by such Optionee shall immediately terminate in its entirety upon first notification to the Optionee of termination of the
Optionee’s Continuous Service Status for Cause. If an Optionee’s Continuous Service Status is suspended pending an investigation of whether the Optionee’s Continuous Service Status will be terminated for Cause, all the Optionee’s
rights under any Option, including the right to exercise the Option, shall be suspended during the investigation period. Nothing in this Section 10(b)(v) shall in any way limit the Company’s right to purchase unvested Shares issued upon
exercise of an Option as set forth in the applicable Option Agreement. 
 (c) Buyout Provisions. The Administrator
may at any time offer to buy out for a payment in cash or Shares an Option previously granted under the Plan based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

 11. Restricted Stock. 
 (a) Rights to Purchase. When a right to purchase Restricted Stock is granted under the Plan, the Administrator shall advise the recipient in writing of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid (which shall be as determined by the Administrator, subject to Applicable Laws, including any applicable securities laws), and
the time within which such person must accept such offer. The permissible consideration for Restricted Stock shall be determined by the Administrator and shall be the same as is set forth in Section 9(b) with respect to exercise of Options. The
offer to purchase Shares shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator. 

  
 -11-









 (b) Repurchase Option. 

(i) General. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the
Company a repurchase option exercisable upon the voluntary or involuntary termination of the Participant’s Continuous Service Status for any reason (including death or Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original purchase price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Administrator
may determine. 
 (ii) Leave of Absence. The Administrator shall have the discretion to determine whether
and to what extent the lapsing of Company repurchase rights shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, such lapsing shall be tolled during any such unpaid leave (unless otherwise
required by the Applicable Laws). Notwithstanding the foregoing, in the event of military leave, the lapsing of Company repurchase rights shall toll during any unpaid portion of such leave, provided that, upon a Participant’s returning from
military leave (under conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Shares purchased pursuant to
the Restricted Stock Purchase Agreement to the same extent as would have applied had the Participant continued to provide services to the Company (or any Parent or Subsidiary, if applicable) throughout the leave on the same terms as he or she was
providing services immediately prior to such leave. 
 (c) Other Provisions. The Restricted Stock Purchase
Agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions of Restricted Stock Purchase Agreements need not be the
same with respect to each Participant. 
 (d) Rights as a Holder of Capital Stock. Once the Restricted Stock is
purchased, the Participant shall have the rights equivalent to those of a holder of capital stock, and shall be a record holder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to the date the Restricted Stock is purchased, except as provided in Section 14 of the Plan. 
 12. Taxes. 
 (a) As a condition of the grant, vesting and exercise
of an Award, the Participant (or in the case of the Participant’s death or a permitted transferee, the person holding or exercising the Award) shall make such arrangements as the Administrator may require for the satisfaction of any applicable
U.S. federal, state or local tax withholding obligations or foreign tax withholding obligations that may arise in connection with such Award. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied.

 (b) The Administrator may permit a Participant (or in the case of the Participant’s death or a permitted transferee, the
person holding or exercising the Award) to satisfy all or part of his

or her tax withholding obligations by Cashless Exercise or by surrendering Shares (either directly or by stock attestation) that he or she previously acquired; provided that, unless the Cashless
Exercise is an approved broker-assisted Cashless Exercise, the Shares tendered for payment have been previously held for a minimum duration (e.g., to avoid financial accounting charges to the Company’s earnings), or as otherwise permitted to
avoid financial accounting charges under applicable accounting guidance, amounts withheld shall not exceed the amount necessary to satisfy the Company’s tax withholding obligations at the minimum statutory withholding rates, including, but not
limited to, U.S. federal and state income taxes, payroll taxes, and foreign taxes, if applicable. Any payment of taxes by surrendering Shares to the Company may be subject to restrictions, including, but not limited to, any restrictions required by
rules of the Securities and Exchange Commission. 
 13. Non-Transferability of Options. 

(a) General. Except as set forth in this Section 13, Options 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. The designation of a beneficiary by an Optionee will not constitute a transfer. An Option may be exercised, during the lifetime of the holder of
the Option, only by such holder or a transferee permitted by this Section 13. 
 (b) Limited Transferability
Rights. Notwithstanding anything else in this Section 13, the Administrator may in its sole discretion grant Nonstatutory Stock Options that may be transferred by instrument to an inter vivos or testamentary trust in which the Options
are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift to Family Members. 
 14. Adjustments
Upon Changes in Capitalization, Merger or Certain Other Transactions. 
 (a) Changes in Capitalization.
Subject to any action required under Applicable Laws by the holders of capital stock of the Company, (i) the numbers and class of Shares or other stock or securities: (x) available for future Awards under Section 3 above, (y) set
forth in Section 8 above, and (z) covered by each outstanding Award, (ii) the price per Share covered by each such outstanding Option, and (iii) any repurchase price per Share applicable to Shares issued pursuant to any Award,
shall be proportionately adjusted by the Administrator in the event of a stock split, reverse stock split, stock dividend, combination, consolidation, recapitalization (including a recapitalization through a large nonrecurring cash dividend) or
reclassification of the Shares, subdivision of the Shares, a rights offering, a reorganization, merger, spin-off, split-up, change in corporate structure or other similar occurrence. Any adjustment by the Administrator pursuant to this
Section 14(a) shall be made in the Administrator’s sole and absolute discretion and shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Award. If, by reason of a transaction described in this Section 14(a) or
an adjustment pursuant to this Section 14(a), a Participant’s Award agreement or agreement related to any Optioned Stock or Restricted Stock covers additional or different shares of stock or securities, then such additional or different
shares, and the Award agreement or agreement related to the Optioned Stock or Restricted Stock in respect thereof, shall be subject to all of the terms, conditions and restrictions which were applicable to the Award, Optioned Stock and Restricted
Stock prior to such adjustment.

 (b) Dissolution or Liquidation. In the event of the dissolution or
liquidation of the Company, each Award will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 
 (c) Corporate Transactions. In the event of a sale of all or substantially all of the Company’s assets, or a merger, consolidation or other capital reorganization or business
combination transaction of the Company with or into another corporation, entity or person (a “Corporate Transaction”), each outstanding Option shall either be (i) assumed or an equivalent option or right shall be substituted by
such successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”), or (ii) terminated in exchange for a payment of cash, securities and/or other property equal to the excess of the
Fair Market Value of the portion of the Optioned Stock that is vested and exercisable immediately prior to the consummation of the Corporate Transaction over the per Share exercise price thereof. Notwithstanding the foregoing, in the event such
Successor Corporation does not agree to such assumption, substitution or exchange, each such Option shall terminate upon the consummation of the Corporate Transaction. 
 15. Time of Granting Options and Right to Purchase Restricted Stock. The date of grant of an Award shall, for all purposes, be the date on which the Administrator makes the
determination granting such Award, or such other date as is determined by the Administrator, provided that in the case of any Incentive Stock Option, the grant date shall be the later of the date on which the Administrator makes the determination
granting such Incentive Stock Option or the date of commencement of the Optionee’s employment relationship with the Company. 
 16. Amendment and Termination of the Plan. The Board may at any time amend or terminate the Plan, but no amendment or termination (other than an adjustment pursuant to Section 14
above) shall be made that would materially and adversely affect the rights of any Participant under any outstanding Award, without his or her consent. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company
shall obtain the approval of holders of capital stock with respect to any Plan amendment in such a manner and to such a degree as required. 
 17. Conditions Upon Issuance of Shares. Notwithstanding any other provision of the Plan or any agreement entered into by the Company pursuant to the Plan, the Company shall not be obligated,
and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. As
a condition to the exercise of any Option or purchase of any Restricted Stock, the Company may require the person exercising the Option or purchasing the Restricted Stock to represent and warrant at the time of any such exercise or purchase 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 by Applicable Laws. Shares issued upon exercise of
Options or purchase of Restricted Stock prior to the date, if ever, on which the Common Stock becomes a Listed Security shall be subject to a right of first refusal in favor of the Company pursuant to which the Participant

will be required to offer Shares to the Company before selling or transferring them to any third party on such terms and subject to such conditions as is reflected in the applicable Option
Agreement or Restricted Stock Purchase Agreement. 
 18. Beneficiaries. Unless stated otherwise in an Award
agreement, a Participant may designate one or more beneficiaries with respect to an Award by timely filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time
before the Participant’s death. If no beneficiary was designated or if no designated beneficiary survives the Participant, then after a Participant’s death any vested Award(s) shall be transferred or distributed to the Participant’s
estate. 
 19. Approval of Holders of Capital Stock. If required by the Applicable Laws, continuance of the Plan
shall be subject to approval by the holders of capital stock of the Company within twelve (12) months before or after the date the Plan is adopted or, to the extent required by Applicable Laws, any date the Plan is amended. Such approval shall
be obtained in the manner and to the degree required under the Applicable Laws. 
 20. Addenda. The Administrator
may approve such addenda to the Plan as it may consider necessary or appropriate for the purpose of granting Awards to Employees or Consultants, which Awards may contain such terms and conditions as the Administrator deems necessary or appropriate
to accommodate differences in local law, tax policy or custom, which, if so required under Applicable Laws, may deviate from the terms and conditions set forth in this Plan. The terms of any such addenda shall supersede the terms of the Plan to the
extent necessary to accommodate such differences but shall not otherwise affect the terms of the Plan as in effect for any other purpose.

 ADDENDUM A 
 2008 Stock Plan 
 (California Participants) 

Prior to the date, if ever, on which the Common Stock becomes a Listed Security and/or the Company is subject to the reporting
requirements of the Exchange Act, the terms set forth herein shall apply to Awards issued to California Participants. All capitalized terms used herein but not otherwise defined shall have the respective meanings set forth in the Plan. 

1. The following rules shall apply to any Option in the event of termination of the Participant’s Continuous Service Status:

 a. If such termination was for reasons other than death, “disability” (as defined below), or Cause, the Participant
shall have at least thirty (30) days after the date of such termination to exercise his or her Option to the extent the Participant is entitled to exercise on his or her termination date, provided that in no event shall the Option be
exercisable after the expiration of the Option term as set forth in the Option Agreement. 
 b. If such termination was due to
death or disability, the Participant shall have at least six (6) months after the date of such termination to exercise his or her Option to the extent the Participant is entitled to exercise on his or her termination date, provided that in no
event shall the Option be exercisable after the expiration of the Option term as set forth in the Option Agreement. 
 “Disability”
for purposes of this Addendum shall mean the inability of the Participant, in the opinion of a qualified physician acceptable to the Company, to perform the major duties of the Participant’s position with the Company or any Parent or Subsidiary
because of the sickness of injury of the Participant. 
 2. Notwithstanding anything stated herein to the contrary, no Option
shall be exercisable on or after the tenth anniversary of the date of grant and any Award agreement shall terminate on or before the tenth anniversary of the date of grant. 
 3. The Company shall furnish summary financial information (audited or unaudited) of the Company’s financial condition and results of operations, consistent with the requirements of Applicable Laws,
at least annually to each California Participant during the period such Participant has one or more Awards outstanding, and in the case of an individual who acquired Shares pursuant to the Plan, during the period such Participant owns such Shares.
The Company shall not be required to provide such information if (i) the issuance is limited to key employees whose duties in connection with the Company assure their access to equivalent information or (ii) the Plan or any agreement
complies with all conditions of Rule 701 of the Securities Act of 1933, as amended; provided that for purposes of determining such compliance, any registered domestic partner shall be considered a “family member” as that term is defined in
Rule 701.
