and/or under any directors’ and officers’ liability insurance coverage which may be in effect from time to time. 
  

	SECTION 3.	STOCK ISSUABLE UNDER THE PLAN; CHANGES IN STOCK; SUBSTITUTION 

 (a) Stock
Issuable. The maximum number of Shares reserved and available for issuance under the Plan shall be 9877 Shares, subject to adjustment as provided in Section 3(b). For purposes of this limitation, the Shares underlying any Awards which are
forfeited, canceled, reacquired by the Company, satisfied without the issuance of Stock or otherwise terminated (other than by exercise) shall be added back to the Shares available for issuance under the Plan. Subject to such overall limitation,
Shares may be issued up to such maximum number pursuant to any type or types of Award. The Shares available for issuance under the Plan may be authorized but unissued Shares or Shares reacquired by the Company and held in its treasury. 

(b) Changes in Stock. Subject to Section 4 hereof, if, as a result of any reorganization, recapitalization, reclassification,
stock dividend, stock split, reverse stock split or other similar change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of
the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Stock or other securities, or, it as a
result of any merger, consolidation or sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for a different number or kind of securities of the Company or any successor entity
(or a parent or subsidiary thereof), the Committee shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, (ii) the number and kind of shares or other securities
subject to any then outstanding Awards under the Plan, (iii) the repurchase price per share subject to each outstanding Award, if any, and (iv) the exercise price and/or exchange price for each share subject to any then outstanding Stock
Options under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options) as to which such Stock Options remain exercisable. The adjustment by the Committee shall be final, binding and
conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Committee in its discretion may make a cash payment in lieu of fractional shares. 

  
  

5 













 The Committee may also adjust the number of shares subject to outstanding Awards and the
exercise price and the terms of outstanding Awards to take into consideration material changes in accounting practices or principles, extraordinary dividends, acquisitions or dispositions of stock or property or any other event if it is determined
by the Committee that such adjustment is appropriate to avoid distortion in the operation of the Plan, provided that no such adjustment shall be made in the case of an Incentive Stock Option, without the consent of the grantee, if it would
constitute a modification, extension or renewal of the Option within the meaning of Section 424(h) of the Code. 
 (c) Substitute
Awards. The Committee may grant Awards under the Plan in 
 substitution for stock and stock based awards held by employees, directors or other key
persons of another corporation in connection with a merger or consolidation of the employing corporation with the Company or a Subsidiary or the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The
Committee may direct that the substitute awards be granted on such terms and conditions as the Committee considers appropriate in the circumstances. Any substitute Awards granted under the Plan shall not count against the share limitation set forth
in Section 3(a). 
  

	SECTION 4.	TREATMENT UPON SALE EVENT OR OTHER EXTRAORDINARY TRANSACTION  

 (a)
Options. 
 (i) In the case of and subject to the consummation of a Sale Event, the Plan and all Options issued hereunder shall
terminate upon the effective time of any such Sale Event unless provision is made in connection with the Sale Event in the sole discretion of the parties thereto for the assumption or continuation of Options theretofore granted by the successor
entity, or the substitution of such Options with new Options of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree
(after taking into account any acceleration hereunder). 
 (ii) In the event of the termination of the Plan and all Options issued
hereunder, each Holder of Options shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Committee, to exercise all such Options which are then exercisable or will become exercisable as
of the effective time of the Sale Event; provided, however, that the exercise of Options not exercisable prior to the Sale Event shall be subject to the consummation of the Sale Event. 

(iii) Notwithstanding anything to the contrary in Section 4(a)(i), in the event of a Sale Event pursuant to which holders of the Stock of
the Company will receive upon consummation thereof a cash payment for each share surrendered in the Sale Event, the Company shall have the right, but not the obligation, to make or provide for a cash payment to the grantees holding vested Options in
exchange for the cancellation thereof, in an amount equal to the difference between (A) the value as determined by the Committee of the consideration payable per share of Stock pursuant to the Sale Event (the “Sale Price”) times the
number of shares of Stock subject to outstanding vested Options (to the extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding vested Options. 

  
  

6 













 (b) Option Shares and Restricted Stock Awards. Unless otherwise provided in an Award
agreement, in the case of and subject to the consummation of a Sale Event, Option Shares and shares of Restricted Stock shall be subject to the repurchase right set forth in Section 9(c)(i) and 9(c)(ii), respectively. 

(c) Unrestricted Stock Awards. Unless otherwise provided in an Award agreement, any shares of Unrestricted Stock shall be treated in a
Sale Event the same as all other Shares then outstanding. 
  

	SECTION 5.	ELIGIBILITY 

 Grantees under the Plan will be such full or part-time officers and
other employees, directors and key persons (including consultants and prospective employees) of the Company and its Subsidiaries as are selected from time to time by the Committee in its sole discretion. 

 

	SECTION 6.	STOCK OPTIONS 

 (a) Nature of Stock Options. A Stock Option is an Award
entitling the recipient to acquire, at such exercise price as determined by the Committee, shares of Stock subject to such restrictions and conditions as the Committee may determine at the time of grant. Conditions may be based on continuing
employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The grant of a Stock Option is contingent on the grantee executing the Stock Option agreement.
The terms and conditions of each such agreement shall be determined by the Committee, and such terms and conditions may differ among individual Awards and grantees. 

Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be
granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be
deemed a Non-Qualified Stock Option. 
 No Incentive Stock Option shall be granted under the Plan
after the date which is ten (10) years from the date the Plan is approved by Board of Directors. 
 (b) Grants of Stock Options.
The Committee in its discretion may grant Stock Options to eligible directors, officers, employees and key persons of the Company or any Subsidiary. Stock Options granted under the Plan shall be subject to the following terms and conditions and
shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Committee shall deem desirable. If the Committee so determines, Stock Options may be granted in lieu of cash compensation at the optionee’s
election, subject to such terms and conditions as the Committee may establish. 

  
  

7 













 (i) Exercise Price. The exercise price per share for the Stock covered by a Stock
Option granted under the Plan shall be determined by the Committee at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. If an employee owns or is deemed to own (by reason of the attribution
rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the option
price of an Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date. 
 (ii) Option
Term. The term of each Stock Option shall be fixed by the Committee, but no Stock Option shall be exercisable more than 10 years after the date the Stock Option is granted. If an employee owns or is deemed to own (by reason of the attribution
rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the term of
such Stock Option shall be no more than five years from the date of grant. 
 (iii) Exercisability; Rights of a Stockholder. Stock
Options shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Committee at or after the grant date. The Committee may at any time accelerate the exercisability of all or any portion of any
Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. An optionee shall not be deemed to have acquired any such shares unless and
until a Stock Option shall have been exercised pursuant to the terms hereof, the Company shall have issued and delivered the shares to the optionee, and the optionee’s name shall have been entered on the books of the Company as a stockholder.

 (iv) Method of Exercise. Stock Options may be exercised in whole or in part, by giving written notice of exercise to the Company,
specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods or as otherwise provided by the Committee: 

(A) In cash, by certified or bank check or other instrument acceptable to the Committee in U.S. funds payable to the order of
the Company in an amount equal to the purchase price of such Option Shares; 
 (B) By the optionee delivering to the Company
a promissory note if the Board has expressly authorized the loan of funds to the optionee for the purpose of enabling or assisting the optionee to effect the exercise of his or her Stock Option; provided that at least so much of the exercise price
as represents the par value of the Stock shall be paid other than with a promissory note if otherwise required by state law; or 

(C) If permitted by the Committee, through the delivery (or attestation to the ownership) of shares of Stock that have been
beneficially owned by the optionee for at least six months and are not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date. 

  
  

8 













 Payment instruments will be received subject to collection. No certificates for shares of
Stock so purchased will be issued to optionee until the Company has completed all steps required by law to be taken in connection with the issuance and sale of the shares, including, without limitation, (i) receipt of a representation from the
optionee at the time of exercise of the Option that the optionee is purchasing the shares for the optionee’s own account and not with a view to any sale or distribution thereof, (ii) the legending of any certificate representing the shares
to evidence the foregoing representations and restrictions, and (iii) obtaining from optionee payment or provision for all withholding taxes due as a result of the exercise of the Option. The delivery of certificates representing the shares of
Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price
for such shares and the fulfillment of any other requirements contained in the Option Award agreement or applicable provisions of laws. In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the
attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of shares attested to. 

(c) Annual Limit on Incentive Stock 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 shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and
subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a
Non-Qualified Stock Option. 
  

	SECTION 7.	RESTRICTED STOCK AWARDS 

 (a) Nature of Restricted Stock Awards. A
Restricted Stock Award is an Award pursuant to which the Company may, in its sole discretion, grant or sell, at such purchase price as determined by the Committee, in its sole discretion, shares of Stock subject to such restrictions and conditions
as the Committee may determine at the time of grant, which purchase price shall be payable in cash or other form of consideration acceptable to the Committee. Conditions may be based on continuing employment (or other service relationship) and/or
achievement of pre-established performance goals and objectives. The grant of a Restricted Stock Award is contingent on the grantee executing the Restricted Stock Award agreement. The terms and conditions of each such agreement shall be determined
by the Committee, and such terms and conditions may differ among individual Awards and grantees. 
 (b) Rights as a Stockholder. Upon
execution of a written instrument setting forth the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the Restricted Stock, subject to such conditions
contained in the written instrument evidencing the Restricted Stock Award. 
 (c) Vesting of Restricted Stock. The Committee at the
time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which Restricted Stock shall become vested, subject to such further
rights of the Company or its assigns as may be specified in the instrument evidencing the Restricted Stock Award. 

  
  

9 













 (d) Record Owner; Dividends. The Holder of Restricted Stock shall be considered the
record owners of and shall be entitled to vote the Shares of Restricted Stock if and to the extent such Shares are entitled to voting rights. The Holder shall be entitled to receive all dividends and any other distributions declared on the Shares;
provided, however, that the Company is under no duty to declare any such dividends or to make any such distribution. The Restricted Stock Award agreement may require or permit the immediate payment, waiver, deferral or investment of dividends
paid on the Restricted Stock. 
  

	SECTION 8.	UNRESTRICTED STOCK AWARDS  

 (a) Grant or Sale of Unrestricted Stock. The
Committee may, in its sole discretion, grant (or sell at par value or such higher purchase price determined by the Committee) an Unrestricted Stock Award to any grantee, pursuant to which such grantee may receive shares of Stock free of any vesting
restrictions under the Plan. Unrestricted Stock Awards may be granted or sold as described in the preceding sentence in respect of past services or other valid consideration, or in lieu of any cash compensation due to such individual. 

(b) Elections to Receive Unrestricted Stock In Lieu of Compensation. Upon the request of a grantee and with the consent of the
Committee, each such grantee may, pursuant to an advance written election delivered to the Company no later than the date specified by the Committee, receive a portion of the cash compensation otherwise due to such grantee in the form of shares of
Unrestricted Stock either currently or on a deferred basis. 
  

	SECTION 9.	TRANSFER RESTRICTIONS; COMPANY RIGHT OF FIRST REFUSAL; COMPANY REPURCHASE RIGHTS 


(a) Restrictions on Transfer. 

(i) Options. No Stock Option shall be transferable by the optionee otherwise than by will or by the laws of descent and distribution
and all Stock Options shall be exercisable, during the optionee’s lifetime, only by the optionee, or by the optionee’s legal representative or guardian in the event of the optionee’s incapacity. The Optionee may elect to designate a
beneficiary by providing written notice of the name of such beneficiary to the Company, and may revoke or change such designation at any time by filing written notice of revocation or change with the Company, and any such beneficiary may exercise
the Optionee’s Stock Option in the event of the Optionee’s death to the extent provided herein. If the Optionee does not designate a beneficiary, or if the designated beneficiary predeceases the Optionee, the legal representative of the
Optionee may exercise this Stock Option in the event of the Optionee’s death to the extent provided herein. Notwithstanding the foregoing, the Committee, in its sole discretion, may provide in the Award agreement regarding a given Option that
the optionee may transfer, without consideration for the transfer, his or her Non-Qualified Stock Options to members of his or her immediate family, to trusts for the benefit of such family members, or to
partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Option. 

  
  

10 













 (ii) Issued Shares. No Issued Shares shall be sold, assigned, transferred, pledged,
hypothecated, given away or in any other manner disposed of or encumbered, whether voluntarily or by operation of law, unless (i) such transfer is in compliance with the terms of the applicable Award, all applicable securities laws (including,
without limitation, the Act), and with the terms and conditions of this Section 9, (ii) such transfer does not cause the Company to become subject to the reporting requirements of the Exchange Act, and (iii) the transferee consents in
writing to be bound by the provisions of the Plan, including this Section 9. In connection with any proposed transfer, the Committee may require the transferor to provide at the transferor’s own expense an opinion of counsel to the
transferor, satisfactory to the Committee, that such transfer is in compliance with all foreign, federal and state securities laws (including, without limitation, the Securities Act). Any attempted disposition of Issued Shares not in accordance with
the terms and conditions of this Section 9 shall be null and void, and the Company shall not reflect on its records any change in record ownership of any Issued Shares as a result of any such disposition, shall otherwise refuse to recognize any
such disposition and shall not in any way give effect to any such disposition of Issued Shares. Subject to the foregoing general provisions, and unless otherwise provided in the agreement with respect to a particular Award, Issued Shares may be
transferred pursuant to the following specific terms and conditions (provided that with respect to any transfer of Restricted Stock, all vesting and forfeiture provisions shall continue to apply only with respect to the original recipient): 

(A) Transfers to Permitted Transferees. The Holder may sell, assign, transfer or give away any or all of the Issued
Shares to Permitted Transferees; provided, however, that following such sale, assignment, or other transfer, such Issued Shares shall continue to be subject to the terms of this Plan (including this Section 9) and such Permitted
Transferee(s) shall, as a condition to any such transfer, deliver a written acknowledgment to that effect to the Company. 

(B) Transfers Upon Death. Upon the death of the Holder, any Issued Shares then held by the Holder at the time of such
death and any Issued Shares acquired thereafter by the Holder’s legal representative shall be subject to the provisions of this Plan, and the Holder’s estate, executors, administrators, personal representatives, heirs, legatees and
distributees shall be obligated to convey such Issued Shares to the Company or its assigns under the terms contemplated hereby. 
 (b)
Right of First Refusal. In the event that a Holder desires at any time to sell or otherwise transfer all or any part of such Holder’s Issued Shares, the Holder first shall give written notice to the Company of the Holder’s intention
to make such transfer. Such notice shall state the number of Issued Shares which the Holder proposes to sell (the “Offered Shares”), the price and the terms at which the proposed sale is to be made and the name and address of the proposed
transferee. At any time within 30 days after the receipt of such notice by the Company, the Company or its assigns may elect to purchase all or any portion of the Offered Shares at the price and on the terms offered by the proposed transferee and
specified in the notice. The Company or its assigns shall exercise this right by mailing or delivering written notice to the Holder within the foregoing 30-day period. If the Company or its assigns elect to
exercise its 

  
  

11 













 
purchase rights under this Section 9(b), the closing for such purchase shall, in any event, take place within 45 days after the receipt by the Company of the initial notice from the Holder.
In the event that the Company or its assigns do not elect to exercise such purchase right, or in the event that the Company or its assigns do not pay the full purchase price within such 45-day period, the
Holder may, within 60 days thereafter, sell the Offered Shares to the proposed transferee and at the same price and on the same terms as specified in the Holder’s notice. Any Shares purchased by such proposed transferee shall no longer be
subject to the terms of the Plan. Any Shares not sold to the proposed transferee shall remain subject to the Plan. 
 (c) Company’s
Right of Repurchase. 
 (i) Right of Repurchase for Option Shares. The Company or its assigns shall have the right and option
upon a Repurchase Event to repurchase from a Holder of Option Shares some or all (as determined by the Company) of the Option Shares held or subsequently acquired upon exercise of a Stock Option by such Holder at the price per share specified below.
Such repurchase right may be exercised by the Company within the later of (A) six months following the date of such Repurchase Event or (B) seven months after the acquisition of such Option Shares upon exercise of a Stock Option (the
“Option Shares Repurchase Period”). The “Option Shares Repurchase Price” shall be equal to the Fair Market Value of the Option Shares, determined as of the date the Committee elects to exercise its repurchase rights in connection
with a Repurchase Event. 
 (ii) Right of Repurchase With Respect to Restricted Stock. Unless otherwise set forth in the agreement
entered into by the recipient and the Company in connection with a Restricted Stock Award, the Company or its assigns shall have the right and option upon a Repurchase Event to repurchase from a Holder of Issued Shares received pursuant to a
Restricted Stock Award some or all (as determined by the Company) of such Issued Shares at the price per share specified below. Such repurchase right may be exercised by the Company within six months following the date of such Repurchase Event (the “Non-Option Shares Repurchase Period”). The “Non-Option Shares Repurchase Price” shall be (i) in the case of Issued Shares which are vested as of the
date of the Repurchase Event, the Fair Market Value of such Issued Shares as of the date the Committee elects to exercise its repurchase rights in connection with a Repurchase Event and (ii) in the case of Issued Shares which have not vested as
of the date of the Repurchase Event, subject to adjustment as provided in Section 3(b), the original per share purchase price paid by the recipient. 

(iii) Procedure. Any repurchase right of the Company shall be exercised by the Company or its assigns by giving the Holder written
notice on or before the last day of the Option Shares Repurchase Period or Non-Option Shares Repurchase Period, as applicable, of its intention to exercise such repurchase right. Upon such notification, the
Holder shall promptly surrender to the Company, free and clear of any liens or encumbrances, any certificates representing the Shares being purchased, together with a duly executed stock power for the transfer of such Shares to the Company or the
Company’s assignee or assignees. Upon the Company’s or its assignee’s receipt of the certificates from the Holder, the Company or its assignee or assignees shall deliver to him, her or them a check for the Option Shares Repurchase
Price or the Non-Option Shares Repurchase Price, as applicable; provided, however, that the Company may pay the Option Shares Repurchase Price or Non-Option
Shares Repurchase Price, as applicable, by offsetting and canceling any indebtedness then owed by the Holder to the Company.

 (d) Drag Along Right. In the event the holders of a majority of the Company’s
equity securities then outstanding (the “Majority Shareholders”) determine to sell or otherwise dispose of all or substantially all of the assets of the Company or all or fifty percent (50%) or more of the capital stock of the Company, in
each case in a transaction constituting a change in control of the Company, to any non-Affiliate(s) of the Company or any of the Majority Shareholders, or to cause the Company to merge with or into or
consolidate with any non-Affiliate(s) of the Company or any of the Majority Shareholders (in each case, the “Buyer”) in a bona fide negotiated transaction (a “Sale”), a Holder of
Issued Shares, including any Permitted Transferees, shall be obligated to and shall upon the written request of the Majority Shareholders: (a) sell, transfer and deliver, or cause to be sold, transferred and delivered, to the Buyer, his or her
Issued Shares (including for this purpose all of such Holder’s or his or her Permitted Transferee’s Issued Shares that presently or as a result of any such transaction may be acquired upon the exercise of an Option (following the payment
of the exercise price therefor)) on substantially the same terms applicable to the Majority Shareholders (with appropriate adjustments to reflect the conversion of convertible securities, the redemption of redeemable securities and the exercise of
exercisable securities as well as the relative preferences and priorities of preferred stock); and (b) execute and deliver such instruments of conveyance and transfer and take such other action, including voting such Issued Shares in favor of
any Sale proposed by the Majority Shareholders and executing any purchase agreements, merger agreements, indemnity agreements, escrow agreements or related documents as the Majority Shareholders or the Buyer may reasonably require in order to carry
out the terms and provisions of this Section 9(d). 
 (e) Escrow Arrangement. 

(i) Escrow. In order to carry out the provisions of Sections 9(b), (c), and (d) of this Agreement more effectively, the Company
shall hold any Issued Shares in escrow together with separate stock powers executed by the Holder in blank for transfer, and any Permitted Transferee shall, as an additional condition to any transfer of Issued Shares, execute a like stock power as
to such Issued Shares. The Company shall not dispose of the Issued Shares except as otherwise provided in this Agreement. In the event of any repurchase by the Company (or any of its assigns), the Company is hereby authorized by the Holder and any
Permitted Transferee, as the Holder’s and each such Permitted Transferee’s attorney-in-fact, to date and complete the stock powers necessary for the transfer
of the Issued Shares being purchased and to transfer such Issued Shares in accordance with the terms hereof. At such time as any Issued Shares are no longer subject to the Company’s repurchase, first refusal and drag along rights, the Company
shall, at the written request of the Holder, deliver to the Holder (or the relevant Permitted Transferee) a certificate representing such Issued Shares with the balance of the Issued Shares to be held in escrow pursuant to this Section 9(e).

 (ii) Remedy. Without limitation of any other provision of this Agreement or other rights, in the event that a Holder, any
Permitted Transferees or any other Person is required to sell a Holder’s Issued Shares pursuant to the provisions of Sections 9(b), (c), or (d) hereof and in the further event that he or she refuses or for any reason fails to deliver to
the Company or its 

  
  

13 













 
designated purchaser of such Issued Shares the certificate or certificates evidencing such Issued Shares together with a related stock power, the Company or such designated purchaser may deposit
the applicable purchase price for such Issued Shares with a bank designated by the Company, or with the Company’s independent public accounting firm, as agent or trustee, or in escrow, for such Holder, any Permitted Transferees or other Person,
to be held by such bank or accounting firm for the benefit of and for delivery to him, her, them or it, and/or, in its discretion, pay such purchase price by offsetting any indebtedness then owed by such Holder as provided above. Upon any such
deposit and/or offset by the Company or its designated purchaser of such amount and upon notice to the Person who was required to sell the Issued Shares to be sold pursuant to the provisions of Sections 9(b), (c), or (d), such Issued Shares shall at
such time be deemed to have been sold, assigned, transferred and conveyed to such purchaser, such Holder shall have no further rights thereto (other than the right to withdraw the payment thereof held in escrow, if applicable), and the Company shall
record such transfer in its stock transfer book or in any appropriate manner. 
 (f) Lockup Provision. A Holder agrees, if requested
by the Company and any underwriter engaged by the Company, not to sell or otherwise transfer or dispose of any Issued Shares (including, without limitation, pursuant to Rule 144 under the Securities Act) held by him or her for such period following
the effective date of any registration statement of the Company filed under the Securities Act as the Company or such underwriter shall specify reasonably and in good faith, not to exceed 180 days in the case of the Company’s initial public
offering or 90 days in the case of any other public offering. 
 (g) Adjustments for Changes in Capital Structure. If as a result of
any reorganization, recapitalization, reclassification, stock dividend, stock split reverse stock split or other similar change in the Common Stock, the outstanding shares of Common Stock are increased or decreased or are exchanged for a different
number or kind of shares of the Company’s stock, the restrictions contained in this Section 9 shall apply with equal force to additional and/or substitute securities, if any, received by Holder in exchange for, or by virtue of his or her
ownership of, Issued Shares. 
 (h) Termination. The terms and provisions of Section 9(b), Section 9(c) and
Section 9(d) shall terminate upon the closing of the Company’s initial public offering or upon consummation of any Sale Event, in either case as a result of which shares of the Company (or a successor entity) of the same class as the
Issued Shares are registered under Section 12 of the Exchange Act and publicly traded on NASDAQ/NMS or any national security exchange. 
  

	SECTION 10.	TAX WITHHOLDING 

 (a) Payment by Grantee. Each grantee shall, no later than
the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the grantee for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the
Committee regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such
taxes from any payment of any kind otherwise due to the grantee. The Company’s obligation to deliver stock certificates to any grantee is subject to and conditioned on any such tax obligations being satisfied by the grantee. 

  
  

14 













 (b) Payment in Stock. Subject to approval by the Committee, a grantee may elect to
have the minimum required tax withholding obligation satisfied, in whole or in part, by (i) authorizing the Company to withhold from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as
of the date the withholding is effected) that would satisfy the withholding amount due, or (ii) transferring to the Company shares of Stock owned by the grantee with an aggregate Fair Market Value (as of the date the withholding is effected)
that would satisfy the minimum withholding amount due. 
  

	SECTION 11.	AMENDMENTS AND TERMINATION 

 The Plan may only be amended with the consent of the
holders of a majority of the outstanding shares of the Company entitled to vote at a meeting of the stockholders. Notwithstanding the foregoing, the Board may, at any time, discontinue the Plan and the Committee may, at any time, cancel any
outstanding Award, provided that no such action shall adversely affect rights under any outstanding Award without the holder’s consent. Nothing in this Section 11 shall limit the Committee’s authority to take any action permitted
pursuant to Section 3(c). 
  

	SECTION 12.	STATUS OF PLAN 

 With respect to the portion of any Award that has not been
exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Committee shall otherwise expressly determine in connection
with any Award or Awards. In its sole discretion, the Committee may authorize the creation of trusts or other arrangements to meet the Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the
existence of such trusts or other arrangements is consistent with the foregoing sentence. 
  

	SECTION 13.	GENERAL PROVISIONS  

 (a) No Distribution; Compliance with Legal
Requirements. The Committee may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof. No shares of Stock
shall be issued pursuant to an Award until all applicable securities law and other legal requirements have been satisfied. The Committee may require the placing of restrictive legends on certificates for Stock and Awards as it deems appropriate.

 (b) Delivery of Stock Certificates. Stock certificates to grantees under this Plan shall be deemed delivered for all purposes when
the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company. 

  
  

15 













 (c) Other Compensation Arrangements; No Employment Rights. Nothing contained in this
Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of
Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary. 
 (d) Loans to Award
Recipients. The Company shall have the authority to make loans to recipients of Awards hereunder (including to facilitate the purchase of shares) and shall further have the authority to issue shares for promissory notes hereunder. 

(e) Designation of Beneficiary. Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries
to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that purpose by the Committee and shall not be effective until received by the Committee.
If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate. 

(f) Legend. Any certificate(s) representing the Issued Shares shall carry substantially the following legend: 

The transferability of this certificate and the shares of stock represented hereby are subject to the restrictions, terms and conditions
(including repurchase and restrictions against transfers) contained in The Echo Nest Corporation 2007 Stock Option and Grant Plan and any agreement entered into thereunder by and between the company and the holder of this certificate (a copy of
which is available at the offices of the company for examination). 
  

	SECTION 14.	EFFECTIVE DATE OF PLAN 

 This Plan shall become effective upon approval by the
stockholders in accordance with applicable law. Subject to such approval by the stockholders and to the requirement that no Stock may be issued hereunder prior to such approval, Stock Options and other Awards may be granted hereunder on and after
adoption of this Plan by the Board. 
  

	SECTION 15.	GOVERNING LAW 

 This Plan and all Awards and actions taken thereunder shall be
governed by, and construed in accordance with, the laws of the State of Delaware, applied without regard to conflict of law principles.

	SECTION 16.	DISPUTE RESOLUTION 

 (a) Except as provided below, any dispute arising out of or
relating to this Plan or any Award made hereunder, or any agreement executed in connection herewith, or the breach, termination or validity of this Plan, any such Award or any such agreement, shall be finally settled by binding arbitration conducted
expeditiously in accordance with the J.A.M.S./Endispute Comprehensive Arbitration Rules and Procedures (the “J.A.M.S. Rules”). The arbitration shall be governed by the United States Arbitration Act, 9 U.S.C. Sections 1-16, and judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction thereof. The place of arbitration shall be Boston, Massachusetts. 

(b) The arbitration shall commence within 60 days of the date on which a written demand for arbitration is filed by any party hereto. In
connection with the arbitration proceeding, the arbitrator shall have the power to order the production of documents by each party and any third-party witnesses. In addition, each party may take up to three (3) depositions as of right, and the
arbitrator may in his or her discretion allow additional depositions upon good cause shown by the moving party. However, the arbitrator shall not have the power to order the answering of interrogatories or the response to requests for admission. In
connection with any arbitration, each party to the arbitration shall provide to the other, no later than seven (7) business days before the date of the arbitration, the identity of all persons that may testify at the arbitration and a copy of
all documents that may be introduced at the arbitration or considered or used by a party’s witness or expert. The arbitrator’s decision and award shall be made and delivered within six (6) months of the selection of the arbitrator.
The arbitrator’s decision shall set forth a reasoned basis for any award of damages or finding of liability. The arbitrator shall not have power to award damages in excess of actual compensatory damages and shall not multiply actual damages or
award punitive damages, and each party hereby irrevocably waives any claim to such damages. 
 (c) The Company, each recipient of an Award
hereunder, each party to an agreement governed hereby and any other holder of Stock issued under this Plan (each, a “Party”) covenants and agrees that such party will participate in the arbitration in good faith. This Section 14
applies equally to requests for temporary, preliminary or permanent injunctive relief, except that in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited purpose of avoiding
immediate and irreparable harm. 
 (d) Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District
Court of competent jurisdiction for the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any
claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an
inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives and agrees not to seek any review by any court
of any other jurisdiction which may be called upon to grant an enforcement of the judgment of any such court. Each Party hereby consents to service of process by registered mail at the address to which notices are to be given. Each Party agrees that
its, his or her submission to jurisdiction and its, his or her consent to 

  
  

17 













 
service of process by mail is made for the express benefit of each other Party. Final judgment against any Party in any such action, suit or proceeding may be enforced in other jurisdictions by
suit, action or proceeding on the judgment, or in any other manner provided by or pursuant to the laws of such other jurisdiction.
