 This Restricted Stock Purchase Agreement (the “Agreement”) is entered into as of                     ,

INC., a Delaware corporation (hereinafter referred to as the “Company”), pursuant to the Company’s 2005 Stock Incentive Plan (the “Plan”). Any capitalized term not defined herein shall have the same meaning
ascribed to it in the Plan. 
 R E C I T A L S: 
 A. Purchaser is an employee, director, Consultant or other Service Provider, and in connection therewith has rendered services for and on behalf of the Company. 
 B. Purchaser and the Company are parties to that certain Stock Option Agreement dated
                    , 200     (the “Option Agreement”). 
 C. The Option Agreement provides the Purchaser with the discretion to early exercise the option covered by the Option Agreement by entering into
this Agreement (and complying with the other requirements set forth therein). 
 D. The Purchaser desires to early exercise his or her
option covered by the Option Agreement. 
 NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth, and for other good
and valuable consideration, the parties agree as follows: 
 1. Issuance of Shares. The Company
hereby agrees to issue to Purchaser, and Purchaser hereby agrees to acquire, an aggregate of                     
(            ) shares of Common Stock of the Company (the “Shares”) on the terms and conditions herein set forth. 
 2. Consideration. The purchase price for the Shares shall be
$             per share (the “Purchase Price”), or $             in the aggregate, which shall be
paid by the delivery of Purchaser’s check payable to the Company or wire to an account designated by the Company contemporaneous with the execution and delivery of this Agreement. 
 3. Vesting of Shares. 
 (a) The Shares acquired hereunder shall vest and become “Vested Shares” as to
             of the Shares on the                      anniversary of the
“Vesting Commencement Date,” and thereafter, the balance of the Shares shall become Vested Shares in a series of              successive equal monthly installments for each
full month of Continuous Service provided by the Purchaser, such that 100% of the Shares shall be Vested Shares on the fourth anniversary of the Vesting Commencement Date. Shares which have not yet become vested are herein called “Unvested
Shares.” No additional shares shall vest after the date of termination of Purchaser’s Continuous Service (the “Termination Date”). For these purposes, the “Vesting Commencement Date” shall be
                    , 200    . 

 For purposes of this Agreement, the term “Continuous Service” means (i) employment
by either the Company or any parent or subsidiary corporation of the Company, or by a corporation or a parent or subsidiary of a corporation issuing or assuming a stock option in a transaction to which Section 424(a) of the Code applies, which
is uninterrupted except for vacations, illness (except for permanent disability, as defined in Section 22(e)(3) of the Code), or leaves of absence which are approved in writing by the Company or any of such other employer corporations, if
applicable, (ii) service as a member of the Board of Directors of the Company until Purchaser resigns, is removed from office, or Purchaser’s term of office expires and he or she is not reelected, or (iii) so long as Purchaser is
engaged as a Consultant or Service Provider. 
 (b) Purchaser shall deposit with the Company certificates representing
the Unvested Shares, together with a duly executed stock assignment separate from certificate in blank, which shall be held by the Secretary of the Company. Purchaser shall be entitled to vote and to receive dividends and distributions on all such
deposited Shares. 
 4. Repurchase Upon Termination of Service. 
 (a) Repurchase Right. The Company shall have the right (but not the obligation) to repurchase (the “Repurchase
Right”) all or any part of the Shares in the event that the Purchaser’s Continuous Service terminates for any reason, including, without limitation, Purchaser’s death, disability, voluntary resignation or termination by the
Company with or without cause. Upon exercise of the Repurchase Right, the Purchaser shall be obligated to sell his or her Shares to the Company, as provided in this Section 4. In the event the Company does not exercise the Repurchase Right with
respect to all of the Shares, the Company shall nevertheless continue to have the “Right of First Refusal” with respect to any remaining Shares during the period and as set forth in Section 5 below. 
 (b) Consideration for Repurchase Right. The repurchase price of the Shares (the “Repurchase Price”)
shall be determined as follows: 
 (i) the Repurchase Price for any Vested Shares shall be equal to the Fair Market
Value of such Vested Shares (determined in accordance with Section 2.14 of the Plan) as of the Termination Date; and 
 (ii) the Repurchase Price for any Unvested Shares shall be equal to the Purchase Price of such Unvested Shares. 
 (c) Procedure for Exercise of Repurchase Right. For sixty (60) days after the Termination Date or other event described in this Section 4, the Company may exercise the Repurchase Right by giving Purchaser
and/or any other person obligated to sell written notice of the number of Shares which the Company desires to purchase. The Repurchase Price for the Shares (as determined pursuant to Section 4(b)) shall be payable, at the option of the Company,
by check or by cancellation of all or a portion of any outstanding indebtedness of Purchaser to the Company, or by any combination thereof. 
  

 2 

 (d) Notification and Settlement. In the event that the Company has
elected to exercise the Repurchase Right as to part or all of the Shares within the period described above, Purchaser or such other person shall deliver to the Company certificate(s) representing the Shares to be acquired by the Company, duly
endorsed for transfer to the Company, within thirty (30) days following the date of the notice from the Company. The Company shall deliver to Purchaser against delivery of the Shares, checks of the Company payable to Purchaser and/or any other
person obligated to transfer the Shares in the aggregate amount of the Repurchase Price to be paid (without any interest thereon and less any amount representing cancellation of indebtedness) as set forth in paragraph 4(b) above. 
 (e) Termination. The provisions of this Section 4 shall automatically terminate, and the Shares shall not be
subject to the Repurchase Right upon the closing of the initial public offering of shares of the Company’s Common Stock pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the
Securities Act (a “Public Offering”). 
 (f) If the Purchaser: (i) files a voluntary petition
under any bankruptcy or insolvency law or a petition for the appointment of a receiver or makes an assignment for the benefit of creditors; (ii) is subjected involuntarily to such a petition or assignment or to an attachment or other legal or
equitable interest with respect to the Shares and such involuntary petition or assignment or attachment is not discharged within sixty (60) days after its date; or (iii) is required to transfer the Shares by operation of law or by order or
decree of any court, then the Company shall have the option to exercise the Repurchase Right, whether or not the Continuous Service of the Purchaser shall then have terminated. 
 (g) The Company may assign its Repurchase Right under this Section 4 and its right of first refusal under Section 5 below
without the consent of the Purchaser. 
 5. Right of First Refusal. 
 (a) The Vested Shares acquired pursuant to this Agreement may be sold by the Purchaser only in compliance with the provisions of
this Section 5, and subject in all cases to compliance with the provisions of Section 9 hereof. Prior to any intended sale, Purchaser shall first give written notice (the “Offer Notice”) to the Company specifying
(i) his or her bona fide intention to sell or otherwise transfer such Vested Shares, (ii) the name and address of the proposed purchaser(s), (iii) the number of Vested Shares the Purchaser proposes to sell (the “Offered
Shares”), (iv) the price for which he or she proposes to sell the Offered Shares, and (v) all other material terms and conditions of the proposed sale. 
 (b) Within thirty (30) days after receipt of the Offer Notice, the Company or its nominee(s) may elect to purchase all or any
portion of the Offered Shares at the price and on the terms and conditions set forth in the Offer Notice by delivery of written notice (the “Acceptance Notice”) to the Purchaser specifying the number of Offered Shares that the
Company or its nominee(s) elect to purchase. Within fifteen (15) days after delivery of the Acceptance Notice to the Purchaser, the Company and/or its nominee(s) shall deliver to the Purchaser a check in the amount of the purchase price of the
Offered Shares to be purchased pursuant to this Section 5, against delivery by the Purchaser of a certificate or certificates representing the Offered Shares to be purchased, duly endorsed for transfer to the Company or such nominee(s), as the
case may be. However, (i) should the purchase price specified in the Offer Notice be payable in property other than cash or evidences of indebtedness, the Company or its nominee(s) shall have the right to pay the purchase price in the form of
cash equal in amount to the value of such property, and (ii) if there is no purchase price for 

  

 3 

 
the intended disposition, the Company or its nominee(s) shall have the right to purchase any or all of the Offered Shares for a purchase price in the form of
cash equal in amount to the value of such Offered Shares. If the Purchaser and the Company or its nominee(s) cannot agree on such cash value within ten (10) days after the Company’s receipt of the Offer Notice, the valuation shall be made
by an appraiser of recognized standing selected by the Purchaser and the Company or its nominee(s) or, if they cannot agree on an appraiser within ten (10) days after the Company’s receipt of such notice, each shall select an appraiser of
recognized standing and the two appraisers shall designate a third appraiser of recognized standing, whose appraisal shall be determinative of such value. 
 (c) If the Company and/or its nominee(s) do not elect to purchase all of the Offered Shares, the Purchaser shall be entitled to sell the balance of the Offered Shares to the purchaser(s) named in the Offer
Notice at the price specified in the Offer Notice or at a higher price and on the terms and conditions set forth in the Offer Notice; provided, however, that any such sale or disposition must not be effected in contravention of the representations
made by the Purchaser in Section 9 of this Agreement. Such sale or other transfer must be consummated within sixty (60) days from the date of the Offer Notice and any proposed sale after such 60-day period may be made only by again
complying with the procedures set forth in this Section 5. 
 (d) The Purchaser may transfer all or any portion of
the Shares to a trust established for the sole benefit of the Purchaser and/or his or her spouse or children without such transfer being subject to the right of first refusal set forth in this Section 5, provided that the Shares so transferred
shall remain subject to the terms and conditions of this Agreement and no further transfer of such Shares may be made without complying with the provisions of this Section 5. 
 (e) Any transferee of the Shares pursuant to this Section 5, shall hold the Shares subject to the terms and conditions of this
Agreement and no further transfer of the Shares may be made without complying with the provisions of this Section 5. 
 (f) The rights provided the Company and its nominee(s) under this Section 5 shall terminate upon the consummation of a Public Offering as defined in Section 4(e) above. 
 6. Purchaser’s Put Right. In the event that the Purchase Price is less than $4.10 per share, as adjusted for any
recapitalizations, stock splits, combinations of shares, reclassifications, stock dividends or other changes in the capital structure of the Company occurring after the reverse stock split effective July 14, 2005: 
 (a) Subject to the provisions of this Section 6, upon the occurrence of any liquidation, dissolution or winding up of the
Company (or a Deemed Liquidation Event as defined in the Company’s Amended and Restated Certificate of Incorporation filed with the Secretary of State of the State of Delaware on July 5, 2005, as amended to date, and as subsequently
amended after the date hereof (the “Restated Certificate”)), either voluntary or involuntary (each, a “Put Event”), Purchaser shall have the right and option (the “Put Right”), exercisable at his or
her sole discretion by giving prior irrevocable written notice to the Company (the “Put Notice”), to sell to the Company, and upon receipt of any such written notice, the Company hereby agrees to repurchase from Purchaser in cash on
the closing of the Put Event, Vested Shares then held by Purchaser and set forth in the Put Notice up to a maximum of fifty percent (50%) of the aggregate number of Shares originally subject to the Option Agreement at a per Share price equal to
the difference between $4.10 and the Exercise Price, with the foregoing amounts subject to appropriate adjustment for recapitalizations, stock splits, combinations of shares, reclassifications, stock dividends or other changes in the capital
structure of the Company occurring after the reverse stock split effective July 14, 2005. 
  

 4 

 (b) The Company shall not be obligated to repurchase the Vested Shares subject to
the Put Notice to the extent that such repurchase would be unlawful. Additionally, the payment of any amounts by the Company hereunder shall be subordinate to (i) the payment of the liquidation preferences for the Company’s Preferred Stock
set forth in the Restated Certificate and (ii) the repayment of indebtedness of the Company, but senior to any liquidation distribution to the holders of Common Stock or Preferred Stock on an as-converted basis (after repayment of the
Company’s indebtedness and payment of the Preferred Stock liquidation preferences). 
 (c) The Put Right may be
exercised in whole or in part in a single instance prior to a Put Event and shall automatically terminate following the occurrence of a Put Event. 
 (d) Notwithstanding anything to the contrary in this Section 6, the Put Right shall terminate and be of no further force and effect immediately upon the Company becoming subject to the reporting
requirements of the Securities Exchange Act of 1934, as amended. 
 7. Adjustments Upon Changes in Capital
Structure. In the event that the outstanding shares of Common Stock of the Company are hereafter increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason
of a recapitalization, stock split, combination of shares, reclassification, stock dividend, or other change in the capital structure of the Company, then Purchaser shall be entitled to new or additional or different shares of stock or securities,
in order to preserve, as nearly as practical, but not to increase, the benefits of Purchaser under this Agreement, in accordance with the provisions of Section 4.3 of the Plan. Such new, additional or different shares shall be deemed Shares for
purposes of this Agreement and subject to all of the terms and conditions hereof. 
 8. Shares Free and
Clear. All Shares purchased by the Company pursuant to this Agreement shall be delivered by Purchaser free and clear of all claims, liens and encumbrances of every nature (except the provisions of this Agreement and any conditions
concerning the Shares relating to compliance with applicable federal or state securities laws), and the purchaser thereof shall acquire full and complete title and right to all of the shares, free and clear of any claims, liens and encumbrances of
every nature (again except for the provisions of this Agreement and such securities laws). 
 9. Investment
Representations. The Purchaser acknowledges that he or she is aware that the Shares to be issued to him by the Company pursuant to this Agreement have not been registered under the Securities Act of 1933, as amended (the
“Act”). In this connection, the Purchaser warrants and represents to the Company as follows: 
 (a)
The Purchaser is purchasing the Shares solely for the Purchaser’s own account for investment and not with a view to or for sale or distribution of the Shares or any portion thereof and not with any present intention of selling, offering to sell
or otherwise disposing of or distributing the Shares or any portion thereof. The Purchaser also represents that the entire legal and beneficial interest of the Shares the Purchaser is purchasing is being purchased for, and will be held for the
account of, the Purchaser only and neither in whole nor in part for any other person. 
  

 5 

 (b) The Purchaser has heretofore discussed the Company and its plans, operations
and financial condition with its officers and that the Purchaser has heretofore received all such information as the Purchaser deems necessary and appropriate to enable the Purchaser to evaluate the financial risk inherent in making an investment in
the Shares of the Company and the Purchaser further represents and warrants that the Purchaser has received satisfactory and complete information concerning the business and financial condition of the Company in response to all inquiries in respect
thereof. 
 (c) The Purchaser realizes that the purchase of the Shares is a highly speculative investment and
represents that the Purchaser is able, without impairing the Purchaser’s financial condition, to hold the Shares for an indefinite period of time and to suffer a complete loss on the investment. 
 (d) The Company hereby discloses to the Purchaser and the Purchaser hereby acknowledges that: 
 (i) the Shares have not been registered under the Act, and such Shares must be held indefinitely unless a transfer of them is
subsequently registered under the Act or an exemption from such registration is available; 
 (ii) the federal
securities laws and the securities laws of the state in which he or she resides may require the placement of certain restrictive legends upon the certificate(s) representing the Shares, and Purchaser hereby consents to the placing of any such
legends upon certificates evidencing the Shares as the Company, or its counsel, may deem necessary or advisable; 
 (iii) the share certificate(s) representing the Shares will be stamped with the legends restricting transfer and noting the other rights and obligations specified in this Agreement, including, without limitation, a legend in
substantially the following form; and 
 “THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON
TRANSFER, DRAG-ALONG RIGHTS, A RIGHT OF FIRST REFUSAL AND A REPURCHASE RIGHT IN FAVOR OF THE COMPANY AND/OR ITS NOMINEE(S), AS SET FORTH IN A RESTRICTED STOCK PURCHASE AGREEMENT DATED
                         , 200_. TRANSFER OF THESE SHARES MAY BE MADE ONLY IN COMPLIANCE WITH THE PROVISIONS OF
SAID AGREEMENT, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY. SUCH TRANSFER RESTRICTIONS, DRAG-ALONG RIGHTS, RIGHT OF FIRST REFUSAL AND REPURCHASE RIGHT ARE BINDING ON TRANSFEREES OF THESE SHARES.” 
 (iv) the Company will make a notation in its records of the aforementioned restrictions on transfer and legends. 
  

 6 

 (e) The Purchaser understands that the Shares are restricted securities within the
meaning of Rule 144 promulgated under the Act; that the exemption from registration under Rule 144 will not be available in any event for at least one (1) year from the date of sale of the Shares to the Purchaser, and even then will not be
available unless (i) a public trading market then exists for the Shares of the Company, (ii) adequate current public information concerning the Company is then available to the public, (iii) the Purchaser has been the beneficial owner
and the Purchaser has paid the full Purchase Price for the Shares at least one (1) year prior to the sale, and (iv) other terms and conditions of Rule 144 are complied with; and that any sale of the Shares may be made by it only in limited
amounts in accordance with such terms and conditions, as amended from time to time. 
 (f) Without in any way limiting
any of the other provisions of this Agreement or its representations set forth above, the Purchaser further agrees that the Purchaser shall in no event make any disposition of all or any portion of the Shares which the Purchaser is purchasing unless
and until: 
 (i) there is then in effect a Registration Statement under the Act covering such proposed disposition
and such disposition is made in accordance with said Registration Statement; or 
 (ii) (A) the Purchaser shall have
notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, (B) the Purchaser shall have furnished the Company with an opinion of
counsel to the effect that such disposition will not require registration of such shares under the Act, and (C) such opinion of counsel shall have been concurred in by counsel for the Company and the Company shall have advised the Purchaser of
such concurrence. 
 (g) Purchaser acknowledges receipt of a copy of the Plan and understands that all rights and
obligations connected with the issuance of the Shares are set forth in this Agreement and in the Plan. 
 10.
Limitation of Company’s Liability for Nonissuance; Unpermitted Transfers. 
 (a) The Company agrees
to use its reasonable best efforts to obtain from any applicable regulatory agency such authority or approval as may be required in order to issue and sell the Shares to Purchaser pursuant to this Agreement. The inability of the Company to obtain,
from any such regulatory agency, authority or approval deemed by the Company’s counsel to be necessary for the lawful issuance and sale of the Shares hereunder and under the Plan shall relieve the Company of any liability in respect of the
nonissuance or sale of such Shares as to which such requisite authority or approval shall not have been obtained. 
 (b) The Company shall not be required to: (i) transfer on its books any Shares of the Company which shall have been sold or transferred in violation of any of the provisions set forth in this Agreement, or (ii) treat as
owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares shall have been so transferred. In the event of a sale of Shares by the Purchaser pursuant to Section 5, the Purchaser
shall furnish to the Company proof that such sale was made in compliance with the provisions of Section 5 as to price and general terms of such sale.

 11. Drag-Along Rights. Purchaser hereby agrees to vote all of the
Shares acquired hereunder in accordance with, and that such Shares shall be subject to, the drag-along rights provisions attached hereto as Appendix A, which are incorporated into this Section 11, as subsequently amended after the date
hereof in connection with any amendments to the Restated Rights Agreement (as defined below) (the “Drag-Along Rights Provisions”). The Drag-Along Rights Provisions are substantially the same provisions as those set forth in Sections
4.3, 4.4, 4.5 and 4.6 of that certain Second Amended and Restated Investors’ Rights and Voting Agreement by and among the Company and the persons identified on Schedule I thereto (the “Investors”), dated July 7, 2005 (the
“Restated Rights Agreement”). For purposes of this Section 11 only, Purchaser shall be an “Investor” as such term is used in the Drag-Along Rights Provisions. 
 12. Change in Control. In the event of a Change in Control (as defined in Section 2.4 of the Plan): 

(a) The vesting of the Shares shall accelerate automatically and in full (notwithstanding the provisions of Section 3
above) effective as of immediately prior to the consummation of the Change in Control unless this Agreement is to be assumed by the acquiring or successor entity (or parent thereof) or a new right or New Incentives are to be issued in exchange
therefor, as provided in subsection (b) below. If the vesting of the Shares subject to this Agreement will accelerate pursuant to this subsection (a), then the Administrator shall cause written notice of the Change in Control transaction to be
given to the Purchaser not less than fifteen (15) days prior to the anticipated effective date of the proposed transaction. 
 (b) The vesting of the Shares shall not accelerate if and to the extent that: (i) this Agreement (including the Unvested Shares represented hereby) is to be assumed by the acquiring or successor entity (or parent thereof) or a
new equity right of comparable value is to be issued in exchange therefor pursuant to the terms of the Change in Control transaction, or (ii) this Agreement (including the Unvested Shares represented hereby) is to be replaced by the acquiring
or successor entity (or parent thereof) with other incentives of comparable value under a new equity incentive program (“New Incentives”) containing such terms and provisions as the Administrator in its discretion may consider
equitable. If this Agreement is assumed, or if a new equity right of comparable value is issued in exchange therefor, then this Agreement or the new equity right shall be appropriately adjusted, concurrently with the Change in Control, to apply to
the number and class of securities or other property that the Purchaser would have received pursuant to the Change in Control transaction in exchange for the Shares represented by this Agreement. 
 13. Interpretation. This issuance of Shares is being made pursuant to the terms of the Plan, and shall in all
respects be interpreted in accordance therewith. The Administrator shall interpret and construe this Agreement and the Plan, and any action, decision, interpretation or determination made in good faith by the Administrator shall be final and binding
on the Company and Purchaser. As used in this Agreement, the term “Administrator” shall refer to the committee of the Board of Directors of the Company appointed to administer the Plan, and if no such committee has been appointed,
the term Administrator shall mean the Board of Directors. 
 14. Notices. Any notice, demand or
request required or permitted to be given under this Agreement shall be in writing and shall be deemed given when delivered personally or three (3) days after being deposited in the United States mail, as certified or registered mail, with
postage prepaid, (or by such other method as the Administrator may from time to time deem appropriate), and addressed, if to the Company, at its principal place of business, Attention: Chief Financial Officer, and if to Purchaser, at his or her most
recent address as shown in the employment or stock records of the Company. 
  

 8 

 15. Binding Obligations. All covenants and agreements herein
contained by or on behalf of any of the parties hereto shall bind and inure to the benefit of the parties hereto and their permitted successors and assigns. 
 16. Captions and Section Headings. Captions and section headings used herein are for convenience only, and are
not part of this Agreement and shall not be used in construing it. 
 17. Amendment. This
Agreement may not be amended, waived, discharged, or terminated other than by written agreement of the parties. 
 18.
Entire Agreement. This Agreement and the Plan constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior or contemporaneous written or oral agreements and understandings
of the parties, either express or implied. Specifically, this Agreement and the Plan supercede the terms of the Option Agreement with respect to the Shares subject to this Agreement. 
 19. Assignment. Purchaser shall have no right, without the prior written consent of the Company, to
(i) sell, assign, mortgage, pledge or otherwise transfer any interest or right created hereby, or (ii) delegate his or her duties or obligations under this Agreement. This Agreement is made solely for the benefit of the parties hereto, and
no other person, partnership, association or corporation shall acquire or have any right under or by virtue of this Agreement. 
 20. Severability. Should any provision or portion of this Agreement be held to be unenforceable or invalid for any reason, the remaining provisions and portions of this Agreement shall be unaffected by such
holding. 
 21. Counterparts. This Agreement may be executed in one or more counterparts, all of
which taken together shall constitute one agreement and any party hereto may execute this Agreement by signing any such counterpart. This Agreement shall be binding upon Purchaser and the Company at such time as the Agreement, in counterpart or
otherwise, is executed by Purchaser and the Company. 
 22. Applicable Law. This Agreement shall
be construed in accordance with the laws of the State of California without reference to choice of law principles, as to all matters, including, but not limited to, matters of validity, construction, effect or performance. 
 23. No Agreement to Employ. Nothing in this Agreement shall affect any right with respect to continuance of
employment by the Company or any of its subsidiaries. The right of the Company or any of its subsidiaries to terminate at will the Purchaser’s employment at any time (whether by dismissal, discharge or otherwise), with or without cause, is
specifically reserved, subject to any other written employment agreement to which the Company and Purchaser may be a party. 
 24. “Market Stand-Off” Agreement. Purchaser agrees that, if requested by the Company or the managing underwriter of any proposed public offering of the Company’s securities, Purchaser will not sell or
otherwise transfer or dispose of any Shares held by Purchaser without the 

  

 9 

 
prior written consent of the Company or such underwriter, as the case may be, during such period of time, not to exceed one hundred eighty (180) days
following the effective date of the registration statement filed by the Company with respect to such offering, as the Company or the underwriter may specify. 
 25. Tax Elections. Purchaser acknowledges that Purchaser has considered the advisability of all tax elections
in connection with the purchase of the Shares hereunder, including the making of an election under Section 83(b) under the Internal Revenue Code of 1986, as amended, and that the Company has no responsibility for the making of any such
election. 
 26. California Corporate Securities Law. The sale of the Shares that are the subject of this
Agreement has not been qualified with the Commissioner of Corporations of the State of California and the issuance of such Shares or the payment or receipt of any part of the consideration therefor prior to such qualification is unlawful, unless the
sale of such Shares is exempt from such qualification by Section 25100, 25102 or 25105 of the California Corporate Securities Law of l968, as amended. The rights of all parties to this Agreement are expressly conditioned upon such qualification
being obtained, unless the sale is so exempt. 
  

 10 

 IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first above written.

 Appendix A 
 1. Drag Along Rights. 
 (a) In the event that the Board of Directors of the Company and the
holders of at least two-thirds of the outstanding shares of the Company’s Series I Preferred Stock (the “Series I Supermajority Holders”) vote to approve or otherwise enter into a transaction with another entity (the
“Purchasing Entity”) that would qualify as a Company Sale (as defined in Section 5 below), then the Series I Supermajority Holders shall have the right to require all other Investors to vote in favor of, consent to and raise no
objection to such Company Sale, and if such right is exercised pursuant to this Section 1, each holder of the Company’s capital stock hereto hereby agrees to vote all of the shares of the Company’s capital stock held by such holder in
favor of such Company Sale. 
 (b) In the event that the Board of Directors and the Series I Supermajority Holders vote to approve or
otherwise enter into a transaction with another entity that would qualify as a Company Sale (such Series I Supermajority Holders are referred to herein as the “Drag-Along Rights Holders”), the Drag-Along Rights Holders shall have
the right to require all other Investors to sell or transfer all of their capital stock of the Company to such unaffiliated purchaser on the same terms and conditions applicable, and for the same type and amount of consideration payable, to such
Drag-Along Rights Holders as determined on a pro rata basis (treating all convertible securities as fully converted into Common Stock for purposes of calculating such Investor’s pro rata share); provided, however, that the aggregate proceeds
from such sale or sales shall be distributed to the selling holders (including holders selling due to the exercise of the rights set forth in this Section 1(b)) in accordance with the rights and preferences set forth in, and assuming the
Company had been liquidated under the appropriate provisions of, the Amended and Restated Certificate of Incorporation (as amended from time to time). In the event the Drag-Along Rights Holders agree to any Company Sale and elect to require all
other Investors to sell or transfer their capital stock pursuant to this Section 1(b), the Drag-Along Rights Holders shall notify the other Investors of such proposed Company Sale (the “Drag Notice”) at least thirty
(30) days prior to the consummation of such proposed Company Sale. 
 (c) The Drag Notice shall set forth (a) a summary description
of the form of the proposed Company Sale, (b) the name of the proposed purchaser and (c) the proposed amount and form of consideration and terms and conditions of payment offered by the proposed purchaser, including copies of any terms
sheet or letter of intent with respect to the proposed Company Sale. Within twenty (20) days after receipt of the Drag Notice, the Investors (other than the Drag-Along Rights Holders) shall take all necessary and reasonably desirable actions in
connection with the consummation of the proposed Company Sale described in the Drag Notice, including, without limitation, (a) executing and delivering agreements and instruments reasonably satisfactory in form and substance to the proposed

shares and the price per share subject to outstanding Option Agreements, Stock Appreciation Rights Agreements and Restricted Stock Award Agreements and the limits on the number of shares under Sections 3.3 and 4.1 all in order to preserve, as nearly
as practical, but not to increase, the benefits to Participants. 
 ARTICLE 5. 
 OPTIONS 
 5.1 Grant of Stock Options. The Administrator shall have the
right to grant pursuant to this Plan, Options subject to such terms, restrictions and conditions as the Administrator may determine at the time of grant. Such conditions may include, but are not limited to, continued employment or the achievement of

Agreements. Each Option granted pursuant to this Plan shall be evidenced by an Option Agreement which shall specify the number of shares subject thereto, vesting provisions relating to such Option, the Exercise Price per share, and
whether the Option is an Incentive Option or Nonqualified Option. As soon as is practical following the grant of an Option, an Option Agreement shall be duly executed and delivered by or on behalf of the Company to the Optionee to whom such Option
was granted. Each Option Agreement shall be in such form and contain such additional terms and conditions, not inconsistent with the provisions of this Plan, as the Administrator shall, from time to time, deem desirable. 
 5.3 Exercise Price. The Exercise Price per share of Common Stock covered by each Option shall be determined by the Administrator, subject to the
following: (a) the Exercise Price of an Incentive Option shall not be less than 100% of Fair Market Value on the date the Incentive Option is granted, (b) the Exercise Price of a Nonqualified Option shall not be less than 100% of Fair
Market Value on the date the Nonqualified Option is granted, and (c) if the person to whom an Incentive Option is granted is a 10% Stockholder on the date of grant, the Exercise Price shall not be less than 110% of Fair Market Value on the date
the Incentive Option is granted. However, an Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner
satisfying the provisions of Section 424 of the Code. 
 5.4 Payment of Exercise Price. Payment of the Exercise Price
shall be made upon exercise of an Option and may be made, in the discretion of the Administrator, subject to any legal restrictions, by: (a) cash; (b) check; (c) the surrender of shares of Common Stock owned by the Optionee (provided
that shares acquired pursuant to the exercise of options granted by the Company must have been held by the Optionee for the requisite period necessary to avoid a charge to the Company’s earnings for financial reporting purposes), which
surrendered shares shall be valued at Fair Market Value as of the date of such exercise; (d) the cancellation of indebtedness of the Company to the Optionee; (e) the waiver of compensation due or accrued to the Optionee for services
rendered; (f) provided that a public market for the Common Stock exists, a “same day sale” commitment from the Optionee and an FINRA Dealer whereby the Optionee irrevocably elects to exercise the Option and to sell a portion of the
shares so purchased to pay for the Exercise Price and whereby the FINRA Dealer irrevocably commits upon receipt of such shares to forward the Exercise Price directly to the Company; (g) provided that a public market for the Common Stock exists,
a 

  

 7 

 
“margin” commitment from the Optionee and an FINRA Dealer whereby the Optionee irrevocably elects to exercise the Option and to pledge the shares
so purchased to the FINRA Dealer in a margin account as security for a loan from the FINRA Dealer in the amount of the Exercise Price, and whereby the FINRA Dealer irrevocably commits upon receipt of such shares to forward the Exercise Price
directly to the Company; or (h) any combination of the foregoing methods of payment or any other consideration or method of payment as shall be permitted by applicable law. 
 5.5 Term and Termination of Options. Except for issuances of Incentive Options to 10% Stockholders, the term and provisions for termination of
each Option shall be as fixed by the Administrator, but no Option may be exercisable more than ten (10) years after the date it is granted. With respect to the issuance of Incentive Options to 10% Stockholders, the term and provisions for
termination of each such Incentive Option shall not exceed five (5) years after the date it is granted. 
 5.6 Vesting and Exercise
of Options. Each Option shall vest and become exercisable in one or more installments, at such time or times and subject to such conditions, including without limitation the achievement of specified performance goals or objectives established
with respect to one or more Performance Criteria, as shall be determined by the Administrator. 
 5.7 Annual Limit on Incentive
Options. To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the Common Stock with respect to which Incentive Options
granted under this Plan and any other plan of the Company or any Affiliated Company become exercisable for the first time by an Optionee during any calendar year shall not exceed $100,000. 
 5.8 Nontransferability of Options. Except as otherwise provided in this Section 5.8, Options shall not be assignable or transferable
except by will, the laws of descent and distribution or pursuant to a DRO entered by a court in settlement of marital property rights, and during the life of the Optionee, Options shall be exercisable only by the Optionee. At the discretion of the
Committee and in accordance with rules it establishes from time to time, Optionees may be permitted to transfer some or all of their Nonqualified Options to one or more “family members,” which is not a “prohibited transfer for
value,” provided that (i) the Optionee (or such Optionee’s estate or representative) shall remain obligated to satisfy all income or other tax withholding obligations associated with the exercise of such Nonqualified Option;
(ii) the Optionee shall notify the Company in writing that such transfer has occurred and disclose to the Company the name and address of the “family member” or “family members” and their relationship to the Optionee, and
(iii) such transfer shall be effected pursuant to transfer documents in a form approved by the Committee. For purposes of the foregoing, the terms “family members” and “prohibited transfer for value” have the meaning
ascribed to them in the General Instructions to form S-8 (or any successor form) promulgated under the Securities Act of 1933, as amended. 
 5.9 Rights as a Stockholder. An Optionee or permitted transferee of an Option shall have no rights or privileges as a stockholder with respect to any shares covered by an Option until such Option has been duly exercised and
certificates representing shares purchased upon such exercise have been issued to such person. 
 5.10 Repricing Prohibited.
Subject to Section 4.2 hereof, without the prior approval of the Company’s stockholders, evidenced by a majority of votes cast, neither the Committee nor the Board shall cause the cancellation, substitution or amendment of an Option
Agreement that would 

  

 8 

 
have the effect of reducing the exercise price of such an Option previously granted under the Plan, or otherwise approve any modification to such an Option
that would be treated as a “repricing” under the then applicable rules, regulations or listing requirements adopted by the Nasdaq Stock Market. 
 5.11 Compliance with Code Section 409A. Notwithstanding anything in this Article 5 to the contrary, all Option Agreements must be structured to satisfy the requirements of Code Section 409A or
an applicable exemption therefrom, as determined by the Committee in its sole discretion.

in such form, and shall set forth the Purchase Price, if any, and such other terms, conditions and restrictions of the Restricted Stock Award Agreement, not inconsistent with the provisions of this Plan, as the Administrator shall, from time to
time, deem desirable. Each such Restricted Stock Award Agreement may be different from each other Restricted Stock Award Agreement. 
  

 10 

 7.3 Purchase Price.  
 (a) Amount. Restricted Stock Units may be issued to Participants for such consideration as is determined by the Administrator in
its sole discretion, including no consideration or such minimum consideration as may be required by applicable law. 
 (b) Payment. Payment of the Purchase Price, if any, may be made, in the discretion of the Administrator, subject to any legal restrictions, by: (a) cash; (b) check; (c) the surrender of shares of Common Stock
owned by the Participant (provided that shares acquired pursuant to the exercise of options granted by the Company shall have been held by the Participant for the requisite period necessary to avoid a charge to the Company’s earnings for
financial reporting purposes), which surrendered shares shall be valued at Fair Market Value as of the date of such acceptance; (d) the cancellation of indebtedness of the Company to the Participant; (e) the waiver of compensation due or
accrued to the Participant for services rendered; or (f) any combination of the foregoing methods of payment or any other consideration or method of payment as shall be permitted by applicable law. 
 7.4 Vesting of Restricted Stock Units. The Restricted Stock Award Agreement shall specify the date or dates, the performance goals, if any,
established by the Committee with respect to one or more Performance Criteria that must be achieved, and any other conditions on which the Restricted Stock Units and may vest. 
 7.5 Rights as a Stockholder. Holders of Restricted Stock Units shall not be entitled to vote or to receive dividends unless or until they
become owners of the shares of Common Stock pursuant to their Restricted Stock Award Agreement and the terms and conditions of the Plan. 
 7.6 Restrictions. Until vested, Restricted Stock Units may not be sold, pledged or otherwise encumbered or disposed of and shall not be assignable or transferable except by will, the laws of descent and distribution or
pursuant to a DRO entered by a court in settlement of marital property rights, except as specifically provided in the Restricted Stock Award Agreement or as authorized by the Administrator. In the event of termination of a Participant’s
employment, service as a director of the Company or Service Provider status for any reason whatsoever (including death or disability), the Restricted Stock Award Agreement may provide that all Restricted Stock Units that have not vested as of such
date shall be automatically forfeited by the Participant. However, if, with respect to such unvested Restricted Stock Units the Participant paid a Purchase Price, the Administrator shall have the right, exercisable at the discretion of the
Administrator, to exercise a Repurchase Right to cancel such unvested Restricted Stock Units upon payment to the Participant of the original Purchase Price. The Participant shall forfeit such unvested Restricted Stock Units upon the
Administrator’s exercise of such right. 
  

 11 

 7.7 Compliance with Code Section 409A. Notwithstanding anything in this Article 7 to
the contrary, all Restricted Stock Award Agreements must be structured to satisfy the requirements of Code Section 409A or an applicable exemption therefrom, as determined by the Committee in its sole discretion. 
 ARTICLE 8. 
 STOCK APPRECIATION
RIGHTS 
 8.1 Grant of Stock Appreciation Rights. A Stock Appreciation Right may be granted to any Participant selected by the
Committee. Stock Appreciation Rights may be granted on a basis that allows for the exercise of the right by the Participant or that provides for the automatic settlement of the right upon a specified date or event. Stock Appreciation Rights shall be
exercisable or subject to settlement at such time or times and upon conditions as may be approved by the Committee, provided that the Committee may accelerate the exercisability or settlement of a Stock Appreciation Right at any time. 
 8.2 Stock Appreciation Rights Agreements. Each Stock Appreciation Right granted pursuant to this Plan shall be evidenced by a Stock Appreciation
Rights Agreement, which shall specify the number of shares subject thereto, vesting provisions relating to such Stock Appreciation Right and the Base Value per share. As soon as is practicable following the grant of a Stock Appreciation Right, a
Stock Appreciation Rights Agreement shall be duly executed and delivered by or on behalf of the Company to the Stock Appreciation Right Holder to whom such Stock Appreciation Right was granted. Each Stock Appreciation Rights Agreement shall be in
such form and contain such additional terms and conditions, not inconsistent with the provisions of this Plan, as the Administrator shall, from time to time, deem desirable. 
 8.3 Base Value. The Base Value per share of Common Stock covered by each Stock Appreciation Right shall be determined by the Administrator, except
that the Base Value of a Stock Appreciation Right shall not be less than 100% of Fair Market Value of the Common Stock on the date the Stock Appreciation Right is granted. 
 8.4 Term and Termination of Stock Appreciation Rights. The term and provisions for termination of each Stock Appreciation Right shall be fixed by
the Administrator, but no Stock Appreciation Right may be exercisable or subject to settlement more than ten (10) years after the date it is granted. 
 8.5 Vesting of Stock Appreciation Rights. Each Stock Appreciation Right shall vest and become exercisable in one or more installments at such time or times and subject to such conditions, including without
limitation the achievement of specified performance goals or objectives established with respect to one or more Performance Criteria, as shall be determined by the Administrator. A Stock Appreciation Right will be exercisable or payable at such time
or times as determined by the Committee, provided that the maximum term of a Stock Appreciation Right shall be ten (10) years from the Date of Grant. 
 8.6 Exercise or Settlement of Stock Appreciation Rights. A Stock Appreciation Right will entitle the holder, upon exercise or other settlement of the Stock Appreciation Right, as applicable, to receive an
amount determined by multiplying: (i) the excess of the Fair Market Value of a share of Common Stock on the date of exercise or settlement of the Stock Appreciation Right 

  

 12 

 
over the Base Value of such Stock Appreciation Right, by (ii) the number of shares as to which such Stock Appreciation Right is exercised or settled.
Upon such exercise or settlement, the Company shall issue to the Stock Appreciation Right Holder a number of shares of Common Stock determined by dividing the amount determined under the preceding sentence by the Fair Market Value of such shares on
the date of exercise or settlement, subject to applicable tax withholding requirements and to such conditions, as are set forth in this Plan and the applicable Stock Appreciation Rights Award Agreement. 
 8.7 Repricing Prohibited. Without the prior approval of the Company’s stockholders, evidenced by a majority of votes cast, neither the
Committee nor the Board shall cause the cancellation, substitution or amendment of a Stock Appreciation Right Award that would have the effect of reducing the base price of such a Stock Appreciation Right previously granted under the Plan, or
otherwise approve any modification to such a Stock Appreciation Right Award that would be treated as a “repricing” under the then applicable rules, regulations or listing requirements adopted by Nasdaq. 
 8.8 Nontransferability of Stock Appreciation Rights. Except as otherwise provided in this Section 8.8, Stock Appreciation Rights shall not be
assignable or transferable except by will, the laws of descent and distribution or pursuant to a DRO entered by a court in settlement of marital property rights, and during the life of the Stock Appreciation Rights Holder, Stock Appreciation Rights
shall be exercisable only by the Stock Appreciation Rights Holder. At the discretion of the Committee and in accordance with rules it establishes from time to time, Stock Appreciation Rights Holders may be permitted to transfer some or all of their
Stock Appreciation Rights to one or more “family members,” which is not a “prohibited transfer for value,” provided that (i) the Stock Appreciation Rights Holder (or such holder’s estate or representative) shall remain
obligated to satisfy all income or other tax withholding obligations associated with the exercise of such Stock Appreciation Right; (ii) the Stock Appreciation Rights Holder shall notify the Company in writing that such transfer has occurred
and disclose to the Company the name and address of the “family member” or “family members” and their relationship to the holder, and (iii) such transfer shall be effected pursuant to transfer documents in a form approved by
the Committee. For purposes of the foregoing, the terms “family members” and “prohibited transfer for value” have the meaning ascribed to them in the General Instructions to form S-8 (or any successor form) promulgated under
the Securities Act of 1933, as amended. 
 8.9 Rights as a Stockholder. A Stock Appreciation Rights Holder or permitted transferee of
a Stock Appreciation Rights Holder shall have no rights or privileges as a stockholder with respect to any shares covered by a Stock Appreciation Right until such Stock Appreciation Right has been duly exercised or settled and certificates
representing shares issued upon such exercise or settlement have been issued to such person. 
 8.10 Compliance with Code
Section 409A. Notwithstanding anything in this Article 8 to the contrary, all Stock Appreciation Rights Awards must be structured to satisfy the requirements of Code Section 409A or an applicable exemption therefrom, as
determined by the Committee in its sole discretion. 
  

 13 

 ARTICLE 9. 
 ADMINISTRATION OF THE PLAN 
 9.1 Administrator. Authority to control and manage the operation
and administration of the Plan shall be vested in the Board, which may delegate such responsibilities in whole or in part to a committee consisting of two (2) or more members of the Board (the “Committee”). Members of the Committee
may be appointed from time to time by, and shall serve at the pleasure of, the Board. The Board may limit the composition of the Committee to those persons necessary to comply with the requirements of Section 162(m) of the Code and

Plan or by law, the Administrator shall have full power and authority: (a) to determine the persons to whom, and the time or times at which, Incentive Options, Nonqualified Options, Stock Appreciation Rights or Restricted Stock Awards shall be
granted, the number of shares to be represented by each Option or Stock Appreciation Right and the number of shares of Common Stock to be subject to Restricted Stock Awards, and the consideration to be received by the Company upon the exercise of
such Options or sale of the Restricted Stock or the Restricted Stock Units governed by such Restricted Stock Awards; (b) to interpret the Plan; (c) to create, amend or rescind rules and regulations relating to the Plan; (d) to
determine the terms, conditions and restrictions contained in, and the form of, Option Agreements, Stock Appreciation Rights Agreements and Restricted Stock Award Agreements; (e) to determine the identity or capacity of any persons who may be
entitled to exercise a Participant’s rights under any Option Agreement, Stock Appreciation Rights Agreement or Restricted Stock Award Agreement under the Plan; (f) to correct any defect or supply any omission or reconcile any inconsistency
in the Plan or in any Option Agreement, Stock Appreciation Rights Agreement or Restricted Stock Award Agreement; (g) to accelerate the vesting of any Option or Stock Appreciation Rights Agreement or waive any repurchase rights of the Company
with respect to Restricted Stock Awards; (h) to extend the expiration date of any Option or Stock Appreciation Rights Agreement; (i) to amend outstanding Option Agreements, Stock Appreciation Rights Agreements and Restricted Stock

necessary or advisable for the administration of the Plan, but only to the extent not contrary to the express provisions of the Plan. Any action, decision, interpretation or determination made in good faith by the Administrator in the exercise of
its authority conferred upon it under the Plan shall be final and binding on the Company and all Participants. 
 9.3 Limitation on
Liability. No employee of the Company or member of the Board or Committee shall be subject to any liability with respect to duties under the Plan unless the person acts fraudulently or in bad faith. To the extent permitted by law, the Company
shall indemnify each member of the Board or Committee, and any employee of the Company with duties under the Plan, who was or is a party, or is threatened to be made a party, to any threatened, pending or completed proceeding, whether civil,
criminal, administrative or investigative, by reason of such person’s conduct in the performance of duties under the Plan.

 ARTICLE 10. 
 CHANGE IN CONTROL 
 10.1 Options and Stock Appreciation Rights. In order to preserve a
Participant’s rights with respect to any outstanding Options and Stock Appreciation Rights in the event of a Change in Control of the Company: 
 (a) Vesting of all outstanding Options and Stock Appreciation Rights shall accelerate automatically effective as of immediately prior to the consummation of the Change in Control unless the Options and
Stock Appreciation Rights are to be assumed by the acquiring or successor entity (or parent thereof) or new options or new stock appreciation rights under a new stock incentive program (“New Incentives”) are to be issued in exchange
therefor, as provided in subsection (b) below. 
 (b) Vesting of outstanding Options and Stock Appreciation Rights
Agreements shall not accelerate if and to the extent that: (i) the Options and Stock Appreciation Rights (including the unvested portion thereof) are to be assumed by the acquiring or successor entity (or parent thereof) or new options
and stock appreciation rights of comparable value are to be issued in exchange therefor pursuant to the terms of the Change in Control transaction, or (ii) the Options and Stock Appreciation Rights (including the unvested portions thereof) are
to be replaced by the acquiring or successor entity (or parent thereof) with New Incentives containing such terms and provisions as the Administrator in its discretion may consider equitable. If outstanding Options or Stock Appreciation Rights are
assumed, or if New Incentives of comparable value are issued in exchange therefor, then each such Option and Stock Appreciation Right or new stock option or new stock appreciation right shall be appropriately adjusted, concurrently with the Change
in Control, to apply to the number and class of securities or other property that the Optionee or Stock Appreciation Rights Holder would have received pursuant to the Change in Control transaction in exchange for the shares issuable upon exercise of
the Option or Stock Appreciation Right had the Option or Stock Appreciation Right been exercised immediately prior to the Change in Control, and appropriate adjustment also shall be made to the Exercise Price such that the aggregate Exercise Price
of each such Option or new option and the aggregate Base Value of each such Stock Appreciation Right or new stock appreciation right shall remain the same as nearly as practicable. 
 (c) If any Option or Stock Appreciation Right is assumed by an acquiring or successor entity (or parent thereof) or a New Incentive
is issued in exchange therefor pursuant to the terms of a Change in Control transaction, then if so provided in an Option Agreement or a Stock Appreciation Right Award Agreement, the vesting of the Option, the Stock Appreciation Right or the New
Incentive shall accelerate if and at such time as the Optionee’s or Stock Appreciation Rights Holder’s service as an employee, director, officer, consultant or other service provider to the acquiring or successor entity (or a parent or
subsidiary thereof) is terminated involuntarily or voluntarily under certain circumstances within a specified period following consummation of the Change in Control, pursuant to such terms and conditions as shall be set forth in the Option Agreement
or Stock Appreciation Rights Agreement, as the case may be. 
 (d) If vesting of outstanding Options will accelerate
pursuant to subsection (a) above, the Administrator in its discretion may provide, in connection with the Change in Control transaction, for the purchase or exchange of each Option for an amount of cash or other property having a value equal to
the difference (or “spread”) between: (x) the value of the cash or other 

  

 15 

 
property that the Optionee would have received pursuant to the Change in Control transaction in exchange for the shares issuable upon exercise of the Option
had the Option been exercised immediately prior to the Change in Control, and (y) the Exercise Price of the Option. 
 (e) The Administrator shall have the discretion to provide in each Option Agreement and Stock Appreciation Rights Agreement other terms and conditions that relate to (i) vesting of such Option or Stock Appreciation Right in the
event of a Change in Control, and (ii) assumption of such Options and Stock Appreciation Rights or issuance of comparable securities or New Incentives in the event of a Change in Control. The aforementioned terms and conditions may vary in each
Option Agreement and Stock Appreciation Agreement, and may be different from and have precedence over the provisions set forth in Sections 10.1(a) - 10.1(d) above. 
 (f) Outstanding Options and Stock Appreciation Rights shall terminate and cease to be exercisable upon consummation of a Change in
Control except to the extent that the Options or Stock Appreciation Rights are assumed by the successor entity (or parent thereof) pursuant to the terms of the Change in Control transaction. 
 (g) If outstanding Options or Stock Appreciation Rights will not be assumed by the acquiring or successor entity (or parent
thereof), the Administrator shall cause written notice of a proposed Change in Control transaction to be given to Optionees and Stock Appreciation Rights Holders not less than fifteen (15) days prior to the anticipated effective date of the
proposed transaction. 
 10.2 Restricted Stock Awards. In order to preserve a Participant’s rights with respect to any
outstanding Restricted Stock Awards in the event of a Change in Control of the Company: 
 (a) All Repurchase Rights
shall automatically terminate immediately prior to the consummation of such Change in Control and any shares of Restricted Stock or Restricted Stock Units subject to such terminated Repurchase Rights, or Restricted Stock Units, whether or not
subject to such terminated Repurchase Rights shall immediately vest in full, except to the extent that in connection with such Change in Control, the acquiring or successor entity (or parent thereof) provides for the continuance or assumption
of Restricted Stock Award Agreements or the substitution of new agreements of comparable value covering shares of a successor corporation, with appropriate adjustments as to the number and kind of shares and purchase price. 
 (b) The Administrator in its discretion may provide in any Restricted Stock Award Agreement that if, upon a Change in Control, the
acquiring or successor entity (or parent thereof) assumes such Restricted Stock Award Agreement or substitutes new agreements of comparable value covering shares of a successor corporation (with appropriate adjustments as to the number and kind of
shares and purchase price), then any Repurchase Right provided for in such Restricted Stock Award Agreement shall terminate, and the shares of Common Stock subject to the terminated Repurchase Right or any substituted shares shall immediately vest
in full, if the Participant’s service as an employee, director, officer, consultant or other service provider to the acquiring or successor entity (or a parent or subsidiary thereof) is terminated involuntarily or voluntarily under certain
circumstances within a specified period following consummation of a Change in Control, pursuant to such terms and conditions as shall be set forth in the Restricted Stock Award Agreement.

 ARTICLE 11. 
 AMENDMENT AND TERMINATION OF THE PLAN 
 11.1 Amendments. The Board may from time to time
alter, amend, suspend or terminate the Plan in such respects as the Board may deem advisable. No such alteration, amendment, suspension or termination shall be made which shall substantially affect or impair the rights of any Participant under an
outstanding Option Agreement or Restricted Stock Award Agreement without such Participant’s consent. The Board may alter or amend the Plan to comply with requirements under the Code relating to Incentive Options or other types of options which
give Optionees more favorable tax treatment than that applicable to Options granted under this Plan as of the date of its adoption. Upon any such alteration or amendment, any outstanding Option granted hereunder may, if the Administrator so
determines and if permitted by applicable law, be subject to the more favorable tax treatment afforded to an Optionee pursuant to such terms and conditions. 
 11.2 Plan Termination. Unless the Plan shall theretofore have been terminated, the Plan shall terminate on the tenth (10th) anniversary of the Effective Date and no Options or Restricted Stock
Awards may be granted under the Plan thereafter, but Option Agreements and Restricted Stock Award Agreements then outstanding shall continue in effect in accordance with their respective terms. 
 ARTICLE 12. 
 TAX WITHHOLDING 

 12.1 Withholding. The Company shall have the power to withhold, or require a Participant to remit to the Company, an amount
sufficient to satisfy any applicable Federal, state, and local tax withholding requirements with respect to any Options exercised or, with respect to the issuance of Restricted Stock, the date that the shares are issued, if the Purchaser makes the
election set forth in Code Section 83(b), or, if the Purchaser does not make such election, then, then with respect to the Restricted Stock Award, as of the date that the applicable restrictions set forth in the Restricted Stock Award Agreement
and the Plan lapse. To the extent permissible under applicable tax, securities and other laws, the Administrator may, in its sole discretion and upon such terms and conditions as it may deem appropriate, permit a Participant to satisfy his or her
obligation to pay any such tax, in whole or in part, up to an amount determined on the basis of the highest marginal tax rate applicable to such Participant, by (a) directing the Company to apply shares of Common Stock to which the Participant
is entitled as a result of the exercise of an Option or as a result of the purchase of or lapse of restrictions on Restricted Stock Awards or (b) delivering to the Company shares of Common Stock owned by the Participant. The shares of Common
Stock so applied or delivered in satisfaction of the Participant’s tax withholding obligation shall be valued at their Fair Market Value as of the date of measurement of the amount of income subject to withholding. 
  

 17 

 ARTICLE 13 
 MISCELLANEOUS 
 13.1 Benefits Not Alienable. Other than as provided above, benefits under the
Plan may not be assigned or alienated, whether voluntarily or involuntarily. Any unauthorized attempt at assignment, transfer, pledge or other disposition shall be without effect. 
 13.2 No Enlargement of Employee Rights. This Plan is strictly a voluntary undertaking on the part of the Company and shall not be deemed to
constitute a contract between the Company and any Participant to be consideration for, or an inducement to, or a condition of, the employment of any Participant. Nothing contained in the Plan shall be deemed to give the right to any Participant to
be retained as an employee of the Company or any Affiliated Company or to interfere with the right of the Company or any Affiliated Company to discharge any Participant at any time. 
 13.3 Application of Funds. The proceeds received by the Company from the sale of Common Stock pursuant to Option Agreements and Restricted Stock
Award Agreements, except as otherwise provided herein, will be used for general corporate purposes.
