 TABLUS, INC. 2006 STOCK PLAN

 SECTION 1. ESTABLISHMENT AND PURPOSE. 
 The purpose of the Plan is to offer selected persons an opportunity to acquire a proprietary interest in the success of the Company, or to increase such interest, by purchasing Shares of the Company’s Stock. The
Plan provides both for the direct award or sale of Shares and for the grant of Options to purchase Shares. Options granted under the Plan may include Nonstatutory Options as well as ISOs intended to qualify under Section 422 of the Code.

 Capitalized terms are defined in Section 12. 
 SECTION 2. ADMINISTRATION. 
 (a) Committees of the Board of Directors. The Plan may be administered by one or
more Committees. Each Committee shall consist of one or more members of the Board of Directors who have been appointed by the Board of Directors. Each Committee shall have such authority and be responsible for such functions as the Board of
Directors has assigned to it. If no Committee has been appointed, the entire Board of Directors shall administer the Plan. Any reference to the Board of Directors in the Plan shall be construed as a reference to the Committee (if any) to whom the
Board of Directors has assigned a particular function. 
 (b) Authority of the Board of Directors. Subject to the provisions of the
Plan, the Board of Directors shall have full authority and discretion to take any actions it deems necessary or advisable for the administration of the Plan. All decisions, interpretations and other actions of the Board of Directors shall be final
and binding on all Purchasers, all Optionees and all persons deriving their rights from a Purchaser or Optionee. 
 SECTION 3. ELIGIBILITY. 

 (a) General Rule. Only Employees, Outside Directors and Consultants shall be eligible for the grant of Nonstatutory Options or the
direct award or sale of Shares. Only Employees shall be eligible for the grant of ISOs. 
 (b) Ten-Percent Stockholders. A person who
owns more than 10% of the total combined voting power of all classes of outstanding stock of the Company, its Parent or any of its Subsidiaries shall not be eligible for designation as an Optionee or Purchaser unless (i) the Exercise Price is
at least 110% of the Fair Market Value of a Share on the date of grant, (ii) the Purchase Price (if any) is at least 100% of the Fair Market Value of a Share and (iii) in the case of an ISO, such ISO by its terms is not exercisable after
the expiration of five years from the date of grant. For purposes of this Subsection (b), in determining stock ownership, the attribution rules of Section 424(d) of the Code shall be applied. 

 SECTION 4. STOCK SUBJECT TO PLAN. 
 (a) Basic Limitation. Not more than 2,600,000 Shares may be issued under the Plan (subject to Subsection (b) below and
Section 8(a)). All of these Shares may be issued upon the exercise of ISOs. The number of Shares that are subject to Options or other rights outstanding at any time under the Plan shall not exceed the number of Shares that then remain available
for issuance under the Plan. The Company, during the term of the Plan, shall at all times reserve and keep available sufficient Shares to satisfy the requirements of the Plan. Shares offered under the Plan may be authorized but unissued Shares or
treasury Shares. 
 (b) Additional Shares. In the event that Shares previously issued under the Plan are reacquired by the Company,
such Shares shall be added to the number of Shares then available for issuance under the Plan. In the event that an outstanding Option or other right for any reason expires or is canceled, the Shares allocable to the unexercised portion of such
Option or other right shall be added to the number of Shares then available for issuance under the Plan. 
 SECTION 5. TERMS AND CONDITIONS OF AWARDS OR
SALES. 
 (a) Stock Purchase Agreement. Each award or sale of Shares under the Plan (other than upon exercise of an Option)
shall be evidenced by a Stock Purchase Agreement between the Purchaser and the Company. Such award or sale shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not
inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Purchase Agreement. The provisions of the various Stock Purchase Agreements entered into under the Plan need not be identical. 
 (b) Duration of Offers and Nontransferability of Rights. Any right to acquire Shares under the Plan (other than an Option) shall automatically
expire if not exercised by the Purchaser within 30 days after the grant of such right was communicated to the Purchaser by the Company. Such right shall not be transferable and shall be exercisable only by the Purchaser to whom such right was
granted. 
 (c) Purchase Price. The Purchase Price of Shares to be offered under the Plan shall not be less than 85% of the Fair
Market Value of such Shares, and a higher percentage may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors shall determine the Purchase Price at its sole discretion. The Purchase Price shall be payable in a
form described in Section 7. 
 (d) Withholding Taxes. As a condition to the purchase of Shares, the Purchaser shall make such
arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with such purchase. 
 (e) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares awarded or sold under the Plan shall be subject to such special forfeiture
conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the applicable Stock Purchase Agreement and 
  

 2 

 
shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of a Purchaser who is not an officer of the Company,
an Outside Director or a Consultant: 
 (i) Any right to repurchase the Purchaser’s Shares at the original Purchase Price
(if any) upon termination of the Purchaser’s Service shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the award or sale of the Shares; 
 (ii) Any such right may be exercised only for cash or for cancellation of indebtedness incurred in purchasing the Shares; and 

(iii) Any such right may be exercised only within 90 days after the termination of the Purchaser’s Service. 
 SECTION 6. TERMS AND CONDITIONS OF OPTIONS. 
 (a) Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company. The Option shall be subject to all applicable terms and conditions of the Plan
and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Option Agreement. The provisions of the various Stock Option Agreements entered
into under the Plan need not be identical. 
 (b) Number of Shares. Each Stock Option Agreement shall specify the number of Shares
that are subject to the Option and shall provide for the adjustment of such number in accordance with Section 8. The Stock Option Agreement shall also specify whether the Option is an ISO or a Nonstatutory Option. 
 (c) Exercise Price. Each Stock Option Agreement shall specify the Exercise Price. The Exercise Price of any Option shall not be less than 100% of
the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b). Subject to the preceding sentence, the Exercise Price shall be determined by the Board of Directors at its sole discretion. The
Exercise Price shall be payable in a form described in Section 7. 
 (d) Exercisability. Each Stock Option Agreement shall
specify the date when all or any installment of the Option is to become exercisable. No Option shall be exercisable unless the Optionee (i) has delivered an executed copy of the Stock Option Agreement to the Company or (ii) otherwise
agrees to be bound by the terms of the Stock Option Agreement. In the case of an Optionee who is not an officer of the Company, an Outside Director or a Consultant, an Option shall become exercisable at least as rapidly as 20% per year over the
five-year period commencing on the date of grant. Subject to the preceding sentence, the Board of Directors shall determine the exercisability provisions of the Stock Option Agreement at its sole discretion. 
 (e) Basic Term. The Stock Option Agreement shall specify the term of the Option. The term shall not exceed 10 years from the date of grant, and a
shorter term may be 
  

 3 

 
required by Section 3(b). Subject to the preceding sentence, the Board of Directors at its sole discretion shall determine when an Option is to expire.

 (f) Termination of Service (Except by Death). If an Optionee’s Service terminates for any reason other than the
Optionee’s death, then the Optionee’s Options shall expire on the earliest of the following occasions: 
 (i) The
expiration date determined pursuant to Subsection (e) above; 
 (ii) The date three months after the termination of the
Optionee’s Service for any reason other than Disability, or such later date as the Board of Directors may determine; or 
 (iii) The date twelve months after the termination of the Optionee’s Service by reason of Disability, or such later date as the Board of Directors may determine. 
 The Optionee may exercise all or part of the Optionee’s Options at any time before the expiration of such Options under the preceding sentence, but only to the extent that such Options had become exercisable
before the Optionee’s Service terminated (or became exercisable as a result of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result of the termination). The balance of such
Options shall lapse when the Optionee’s Service terminates. In the event that the Optionee dies after the termination of the Optionee’s Service but before the expiration of the Optionee’s Options, all or part of such Options may be
exercised (prior to expiration) by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent
that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result
of the termination). 
 (g) Leaves of Absence. For purposes of Subsection (f) above, Service shall be deemed to continue while
the Optionee is on a bona fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for this purpose is expressly required by the terms of such leave or by applicable law (as determined by the
Company). 
 (h) Death of Optionee. If an Optionee dies while the Optionee is in Service, then the Optionee’s Options shall
expire on the earlier of the following dates: 
 (i) The expiration date determined pursuant to Subsection (e) above; or

 (ii) The date twelve months after the Optionee’s death, or such later date as the Board of Directors may determine.

  

 4 

 All or part of the Optionee’s Options may be exercised at any time before the expiration of such Options under the
preceding sentence by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that such
Options had become exercisable before the Optionee’s death (or became exercisable as a result of the death) and the underlying Shares had vested before the Optionee’s death (or vested as a result of the Optionee’s death). The balance
of such Options shall lapse when the Optionee dies. 
 (i) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares issued
upon exercise of an Option shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the
applicable Stock Option Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of an Optionee who is not an officer of the Company, an Outside Director or a Consultant: 
 (i) Any right to repurchase the Optionee’s Shares at the original Exercise Price upon termination of the Optionee’s Service
shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the option grant; 
 (ii) Any such right may be exercised only for cash or for cancellation of indebtedness incurred in purchasing the Shares; and 
 (iii) Any such right may be exercised only within 90 days after the later of (A) the termination of the Optionee’s Service or (B) the date of the option exercise. 
 (j) Transferability of Options. An Option shall be transferable by the Optionee only by (i) a beneficiary designation, (ii) a will or
(iii) the laws of descent and distribution, except as provided in the next sentence. If the applicable Stock Option Agreement so provides, a Nonstatutory Option shall also be transferable by gift or domestic relations order to a Family Member
of the Optionee. An ISO may be exercised during the lifetime of the Optionee only by the Optionee or by the Optionee’s guardian or legal representative. 
 (k) Withholding Taxes. As a condition to the exercise of an Option, the Optionee shall make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign
withholding tax obligations that may arise in connection with such exercise. The Optionee shall also make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax
obligations that may arise in connection with the disposition of Shares acquired by exercising an Option. 
 (l) No Rights as a
Stockholder. An Optionee, or a transferee of an Optionee, shall have no rights as a stockholder with respect to any Shares covered by the Optionee’s Option until such person becomes entitled to receive such Shares by filing a notice of
exercise and paying the Exercise Price pursuant to the terms of such Option. 
 (m) Modification, Extension and Assumption of Options.
Within the limitations of the Plan, the Board of Directors may modify, extend or assume outstanding 

  

 5 

 
Options or may accept the cancellation of outstanding Options (whether granted by the Company or another issuer) in return for the grant of new Options for
the same or a different number of Shares and at the same or a different Exercise Price. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair the Optionee’s rights or increase the
Optionee’s obligations under such Option. 
 SECTION 7. PAYMENT FOR SHARES. 
 (a) General Rule. The entire Purchase Price or Exercise Price of Shares issued under the Plan shall be payable in cash or cash equivalents at the
time when such Shares are purchased, except as otherwise provided in this Section 7. 
 (b) Services Rendered. At the discretion
of the Board of Directors, Shares may be awarded under the Plan in consideration of services rendered to the Company, a Parent or a Subsidiary prior to the award. 
 (c) Promissory Note. At the discretion of the Board of Directors, all or a portion of the Purchase Price or Exercise Price (as the case may be) of Shares issued under the Plan may be paid with a full-recourse
promissory note. The Shares shall be pledged as security for payment of the principal amount of the promissory note and interest thereon. The interest rate payable under the terms of the promissory note shall not be less than the minimum rate (if
any) required to avoid the imputation of additional interest under the Code. Subject to the foregoing, the Board of Directors (at its sole discretion) shall specify the term, interest rate, amortization requirements (if any) and other provisions of
such note. 
 (d) Surrender of Stock. At the discretion of the Board of Directors, all or any part of the Exercise Price may be paid
by surrendering, or attesting to the ownership of, Shares that are already owned by the Optionee. Such Shares shall be surrendered to the Company in good form for transfer and shall be valued at their Fair Market Value as of the date when the Option
is exercised. 
 (e) Exercise/Sale. To the extent that a Stock Option Agreement so provides, and if Stock is publicly traded, all or
part of the Exercise Price and any withholding taxes may be paid by the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities broker approved by the Company to sell Shares and to deliver all or part of the sales
proceeds to the Company. 
 (f) Other Forms of Payment. To the extent that a Stock Purchase Agreement or Stock Option Agreement so
provides, the Purchase Price or Exercise Price of Shares issued under the Plan may be paid in any other form permitted by the Delaware General Corporation Law, as amended. 
 SECTION 8. ADJUSTMENT OF SHARES. 
 (a) General. In the event of a subdivision of the
outstanding Stock, a declaration of a dividend payable in Shares, a combination or consolidation of the outstanding Stock into a lesser number of Shares, a reclassification, or any other increase or decrease in the 

  

 6 

 
number of issued shares of Stock effected without receipt of consideration by the Company, proportionate adjustments shall automatically be made in each of
(i) the number of Shares available for future grants under Section 4, (ii) the number of Shares covered by each outstanding Option and (iii) the Exercise Price under each outstanding Option. In the event of a declaration of an
extraordinary dividend payable in a form other than Shares in an amount that has a material effect on the Fair Market Value of the Stock, a recapitalization, a spin-off, or a similar occurrence, the Board of Directors at its sole discretion may make
appropriate adjustments in one or more of (i) the number of Shares available for future grants under Section 4, (ii) the number of Shares covered by each outstanding Option or (iii) the Exercise Price under each outstanding
Option. 
 (b) Change in Control. In the event that the Company is a party to a Change in Control, all outstanding Options shall be
subject to the agreement evidencing the Change in Control. Such agreement shall provide for one or more of the following, without the Optionee’s consent: 
 (i) The continuation of such outstanding Options by the Company (if the Company is the surviving corporation). 
 (ii) The assumption of such outstanding Options by the surviving corporation or its parent in a manner that complies with
Section 424(a) of the Code (whether or not such Options are ISOs). 
 (iii) The substitution by the surviving corporation
or its parent of new options for such outstanding Options in a manner that complies with Section 424(a) of the Code (whether or not such Options are ISOs). 
 (iv) The acceleration of exercisability of each such outstanding Option and vesting acceleration of the Shares subject to each such
Option, such that each such outstanding Option shall become exercisable with respect to an additional portion of the Option equal to twenty-five percent (25%) of the then unexercisable portion of the Option and twenty-five percent (25%) of
the then unvested Shares subject to each such Option shall become vested, with the remaining unexercisable portion of each such Option and unvested Shares subject to each such Option becoming exercisable and vested in accordance with the vesting
schedule set forth in each Stock Option Agreement evidencing each such Option. The acceleration of exercisability of such Options and acceleration of vesting of the Shares subject to such Options may be contingent on the closing of such Change in
Control. The Board of Directors may, in its sole discretion, approve additional acceleration of exercisability and vesting acceleration for any outstanding Options, and such additional acceleration does not have to apply to all Options in the same
manner. 
 (v) The cancellation of such outstanding Options and a payment to the Optionees equal to the excess of (A) the
Fair Market Value of the Shares subject to such Options (whether or not such Options are then exercisable or such Shares are then vested) as of the closing date of such Change in Control 

  

 7 

 
over (B) their Exercise Price. Such payment shall be made in the form of cash, cash equivalents, or securities of the surviving corporation or its
parent with a Fair Market Value equal to the required amount. Such payment may be made in installments and may be deferred until the date or dates when such Options would have become exercisable or such Shares would have vested. Such payment may be
subject to vesting based on the Optionee’s continuing Service, provided that the vesting schedule shall not be less favorable to the Optionee than the schedule under which such Options would have become exercisable or such Shares would have
vested. If the Exercise Price of the Shares subject to such Options exceeds the Fair Market Value of such Shares, then such Options may be cancelled without making a payment to the Optionees. For purposes of this Paragraph (v), the Fair Market
Value of any security shall be determined without regard to any vesting conditions that may apply to such security. 
 Immediately following
a Change in Control, all outstanding Options shall terminate and cease to be outstanding, except to the extent such Options have been assumed, continued or substituted, as set forth above in Sections 8(b)(i), (ii) and/or (iii). 
 (c) Reservation of Rights. Except as provided in this Section 8, an Optionee or Purchaser shall have no rights by reason of (i) any
subdivision or consolidation of shares of stock of any class, (ii) the payment of any dividend or (iii) any other increase or decrease in the number of shares of stock of any class. Any issuance by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or Exercise Price of Shares subject to an Option. The grant of an Option pursuant to
the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or transfer all
or any part of its business or assets. 
 SECTION 9. SECURITIES LAW REQUIREMENTS. 
 (a) General. Shares shall not be issued under the Plan unless the issuance and delivery of such Shares comply with (or are exempt from) all
applicable requirements of law, including (without limitation) the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, state securities laws and regulations, and the regulations of any stock exchange or other
securities market on which the Company’s securities may then be traded. 
 (b) Financial Reports. The Company each year shall
furnish to Optionees, Purchasers and stockholders who have received Stock under the Plan its balance sheet and income statement, unless such Optionees, Purchasers or stockholders are key Employees whose duties with the Company assure them access to
equivalent information. Such balance sheet and income statement need not be audited. 
  

 8 

 SECTION 10. NO RETENTION RIGHTS. 
 Nothing in the Plan or in any right or Option granted under the Plan shall confer upon the Purchaser or Optionee any right to continue in Service for any
period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining the Purchaser or Optionee) or of the Purchaser or Optionee, which rights are hereby
expressly reserved by each, to terminate his or her Service at any time and for any reason, with or without cause. 
 SECTION 11. DURATION AND
AMENDMENTS. 
 (a) Term of the Plan. The Plan, as set forth herein, shall become effective on the date of its adoption by
the Board of Directors, subject to the approval of the Company’s stockholders. If the stockholders fail to approve the Plan within 12 months after its adoption by the Board of Directors, then any grants, exercises or sales that have already
occurred under the Plan shall be rescinded and no additional grants, exercises or sales shall thereafter be made under the Plan. The Plan shall terminate automatically 10 years after the later of (i) the date when the Board of Directors adopted
the Plan or (ii) the date when the Board of Directors approved the most recent increase in the number of Shares reserved under Section 4 that was also approved by the Company’s stockholders. The Plan may be terminated on any earlier

 (b) Right to Amend or Terminate the Plan. The Board of Directors may amend, suspend or
terminate the Plan at any time and for any reason; provided, however, that any amendment of the Plan shall be subject to the approval of the Company’s stockholders if it (i) increases the number of Shares available for issuance under the
Plan (except as provided in Section 8) or (ii) materially changes the class of persons who are eligible for the grant of ISOs. Stockholder approval shall not be required for any other amendment of the Plan. If the stockholders fail to
approve an increase in the number of Shares reserved under Section 4 within 12 months after its adoption by the Board of Directors, then any grants, exercises or sales that have already occurred in reliance on such increase shall be rescinded
and no additional grants, exercises or sales shall thereafter be made in reliance on such increase. 
 (c) Effect of Amendment or
Termination. No Shares shall be issued or sold under the Plan after the termination thereof, except upon exercise of an Option granted prior to such termination. The termination of the Plan, or any amendment thereof, shall not affect any Share

to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, including the power to delegate to a subcommittee any of the administrative powers the Committee is

	4.	SHARES SUBJECT TO THE PLAN.

 (b) Reversion of Shares
to the Share Reserve. If any Stock Award shall for any reason expire or otherwise terminate, in whole or in part, without having been exercised in full, the shares of Common Stock not acquired under such Stock Award shall revert to and again
become available for issuance under the Plan. 
  

 6. 

 (b) Reversion of Shares to the Share Reserve. If any Stock Award shall for any reason expire or
otherwise terminate, in whole or in part, without having been exercised in full, or if any shares of Common Stock issued to a Participant pursuant to a Stock Award are forfeited back to or repurchased by the Company, including, but not limited to,
any repurchase or forfeiture caused by the failure to meet a contingency or condition required for the vesting of such shares, then the shares of Common Stock not acquired under such Stock Award shall revert to and again become available for
issuance under the Plan; provided, however, that subject to the provisions of Section 11(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued as Incentive Stock Options
shall be two million (2,000,000) shares of Common Stock. If any shares subject to a Stock Award are not delivered to a Participant because such shares are withheld for the payment of taxes or the Stock Award is exercised through a reduction of
shares subject to the Stock Award (i.e., “net exercised”), then the number of shares that are not delivered shall revert to and again become available for issuance under the Plan. If the exercise price of any Stock Award is
satisfied by tendering shares of Common Stock held the Participant (either by actual deliver or attestation), then the number of such tendered shares shall revert to and again become available for issuance under the Plan. 
 (c) Source of Shares. The shares of Common Stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or
otherwise. 
  

	5.	ELIGIBILITY. 

 (a) Eligibility for
Specific Stock Awards. Incentive Stock Options may be granted only to Employees. Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants. 
 (b) Ten Percent Stockholders. A Ten Percent Stockholder shall not be granted an Incentive Stock Option unless the exercise price of such Option is
at least one hundred ten percent (110%) of the Fair Market Value of the Common Stock on the date of grant and the Option is not exercisable after the expiration of five (5) years from the date of grant. 
 (c) Consultants. A Consultant shall not be eligible for the grant of a Stock Award if, at the time of grant, either the offer or the sale of the
Company’s securities to such Consultant is not exempt under Rule 701 of the Securities Act (“Rule 701”) because of the nature of the services that the Consultant is providing to the Company, because the Consultant is not a natural
person, or because of some other provision of Rule 701. 
  

	6.	OPTION PROVISIONS. 

 Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and,
if certificates are issued, a separate certificate or certificates shall be issued for shares of Common Stock purchased on exercise of each type of Option. The provisions of separate Options need not be identical, but each Option shall include
(through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: 
  

 7. 

 (a) Term. Subject to the provisions of Section 5(b) regarding Ten Percent Stockholders, no
Incentive Stock Option granted shall be exercisable after the expiration of ten (10) years from the date on which it was granted. 
 (b) Exercise Price of an Incentive Stock Option. Subject to the provisions of Section 5(b) regarding Ten Percent Stockholders, the exercise price of each Incentive Stock Option shall be not less than one hundred percent
(100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Incentive Stock 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(a) of the Code. 
 (c) Exercise Price of a Nonstatutory Stock Option. The exercise price of each Nonstatutory Stock Option shall be not less than eighty-five percent
(85%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, a Nonstatutory Stock 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(a) of the Code. 
 (d) Consideration. The purchase price of Common Stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes
and regulations, either (i) in cash at the time the Option is exercised or (ii) at the discretion of the Board at the time of the grant of the Option (or subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the
Company of other Common Stock, (2) according to a deferred payment or other similar arrangement with the Optionholder or (3) by a “net exercise” of the Option (as further described below) (4) pursuant to a program developed
under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instruction to pay the aggregate exercise price
to the Company from the sales proceeds or (5) in any other form of legal consideration that may be acceptable to the Board. Unless otherwise specifically provided in the Option, the purchase price of Common Stock acquired pursuant to an Option
that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held for more than six (6) months (or such longer or
shorter period of time required to avoid a charge to earnings for financial accounting purposes). At any time that the Company is incorporated in Delaware, payment of the Common Stock’s “par value,” as defined in the Delaware General
Corporation Law, shall not be made by deferred payment. 
 In the case of any deferred payment arrangement, interest shall be compounded at
least annually and shall be charged at the minimum rate of interest necessary to avoid (1) the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the deferred
payment arrangement and (2) the treatment of the Option as a variable award for financial accounting purposes. 
  

 8. 

 In the case of a “net exercise” of an Option, the Company will not require a payment of the
exercise price of the Option from the Participant but will reduce the number of shares of Common Stock issued upon the exercise by the largest number of whole shares that has a Fair Market Value that does not exceed the aggregate exercise price.
With respect to any remaining balance of the aggregate exercise price, the Company shall accept a cash payment from the Participant. The shares of Common Stock so used to pay the exercise price of an Option under a “net exercise” will be
considered to have resulted from the exercise of the Option, and accordingly, the Option will not again be exercisable with respect to such shares, the shares actually delivered to the Participant, and any shares withheld for purposes of tax
withholding. 
 (e) Transferability of an Incentive Stock Option. An Incentive Stock Option shall not be transferable except by will
or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option. 
 (f) Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock Option shall be transferable to the extent provided in the Option Agreement. If the Nonstatutory Stock Option does not provide for
transferability, then the Nonstatutory Stock Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the
foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

 (g) Vesting Generally. The total number of shares of Common Stock subject to an Option may, but need not, vest and therefore become
exercisable in periodic installments that may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may
deem appropriate. The vesting provisions of individual Options may vary. The provisions of this Section 6(g) are subject to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be exercised.

 (h) Termination of Continuous Service. In the event that an Optionholder’s Continuous Service terminates (other than upon the
Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination) but only within such period of time ending on the
earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of the Option as
set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. 
 (i) Extension of Termination Date. An Optionholder’s Option Agreement may also provide that if the exercise of the Option following the
termination of the Optionholder’s Continuous Service (other than upon the Optionholder’s death or Disability) would be prohibited 

  

 9. 

 
at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option shall
terminate on the earlier of (i) the expiration of the term of the Option set forth in Section 6(a) or (ii) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during
which the exercise of the Option would not be in violation of such registration requirements. 
 (j) Disability of Optionholder. In
the event that an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of
the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination (or such longer or shorter period specified in the Option Agreement) or (ii) the
expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate. 
 (k) Death of Optionholder. In the event that (i) an Optionholder’s Continuous Service terminates as a result of the Optionholder’s
death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may be exercised (to the extent
the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option
upon the Optionholder’s death pursuant to Section 6(e) or 6(f), but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the
Option Agreement) or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate. 
 (l) Early Exercise. The Option may, but need not, include a provision whereby the Optionholder may elect at any time before the
Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. Any unvested shares of Common Stock so purchased may be
subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. The Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of
time required to avoid a charge to earnings for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option. 
 (m) Right of Repurchase. The Option may, but need not, include a provision whereby the Company may elect to repurchase all or any part of the
vested shares of Common Stock acquired by the Optionholder pursuant to the exercise of the Option. The Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid a
charge to earnings for financial accounting purposes) have elapsed following exercise of the Option otherwise specifically provided in the Option. 
 (n) Right of First Refusal. The Option may, but need not, include a provision whereby the Company may elect to exercise a right of first refusal following receipt of notice 

  

 10. 

 
from the Optionholder of the intent to transfer all or any part of the shares of Common Stock received upon the exercise of the Option. Except as expressly
provided in this Section 6(n) or in the Stock Award Agreement for the Option, such right of first refusal shall otherwise comply with any applicable provisions of the Bylaws of the Company. The Company will not exercise its right of first
refusal until at least six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) have elapsed following the exercise of the Option unless otherwise specifically provided
in the Option. 
  

	7.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

 (a) Restricted Stock Awards. Each Restricted Stock Award agreement shall be in such form and shall contain such
terms and conditions as the Board shall deem appropriate. The terms and conditions of Restricted Stock Award agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award agreements need not be identical;
provided, however, that each Restricted Stock Award agreement shall include (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 
 (i) Purchase Price. At the time of the grant of a Restricted Stock Award, the Board will determine the price to be paid by the Participant for each
share subject to the Restricted Stock Award. To the extent required by applicable law, the price to be paid by the Participant for each share of the Restricted Stock Award will not be less than the par value of a share of Common Stock. A Restricted
Stock Award may be awarded as a stock bonus (i.e., with no cash purchase price to be paid) to the extent permissible under applicable law. 
 (ii) Consideration. At the time of the grant of a Restricted Stock Award, the Board will determine the consideration permissible for the payment of the purchase price of the Restricted Stock Award. The purchase price of Common Stock
acquired pursuant to the Restricted Stock Award shall be paid in one of the following ways: (i) in cash at the time of purchase; (ii) at the discretion of the Board, according to a deferred payment or other similar arrangement with the
Participant; (iii) by services rendered or to be rendered to the Company; or (iv) in any other form of legal consideration that may be acceptable to the Board; provided, however, that at any time that the Company is incorporated in
Delaware, the Common Stock’s “par value,” as defined in the Delaware General Corporation Law, shall not be paid by deferred payment and must be paid in a form of consideration that is permissible under the Delaware Corporation Law.

 (iii) Vesting. Shares of Common Stock acquired under a Restricted Stock Award may, but need not, be subject to a share repurchase
option in favor of the Company in accordance with a vesting schedule to be determined by the Board. 
 (iv) Termination of
Participant’s Continuous Service. In the event that a Participant’s Continuous Service terminates, the Company may repurchase or otherwise reacquire any or all of the shares of Common Stock held by the Participant that have not vested
as of the date of termination under the terms of the Restricted Stock Award agreement. The Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid a charge to
earnings for financial accounting purposes) 

  

 11. 

 
have elapsed following the purchase of the restricted stock unless otherwise determined by the Board or provided in the Restricted Stock Award agreement.

 (v) Transferability. Rights to purchase or receive shares of Common Stock granted under a Restricted Stock Award shall be

remains subject to the terms of the Restricted Stock Award agreement. 
 (b) Stock Appreciation Rights. Each Stock Appreciation Right
agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of Stock Appreciation Right agreements may change from time to time, and the terms and conditions of separate
Stock Appreciation Rights agreements need not be identical, but each Stock Appreciation Right agreement shall include (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following
provisions: 
 (i) Calculation of Appreciation. Each Stock Appreciation Right will be denominated in share of Common Stock equivalents.
The appreciation distribution payable on the exercise of a Stock Appreciation Right will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the Stock Appreciation Right) of a
number of shares of Common Stock equal to the number of share of Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right and with respect to which the Participant is exercising the Stock Appreciation Right on
such date, over (B) an amount that will be determined by the Committee at the time of grant of the Stock Appreciation Right. 
 (ii)
Vesting. At the time of the grant of a Stock Appreciation Right, the Board may impose such restrictions or conditions to the vesting of such Right as it deems appropriate. 
 (iii) Exercise. To exercise any outstanding Stock Appreciation Right, the Participant must provide written notice of exercise to the Company in
compliance with the provisions of the Stock Appreciation Rights agreement evidencing such Right. 
 (iv) Payment. The appreciation
distribution in respect of a Stock Appreciation Right may be paid in Common Stock, in cash, or any combination of the two, as the Board deems appropriate. 
 (v) Termination of Continuous Service. If a Participant’s Continuous Service terminates for any reason, any unvested Stock Appreciation Rights shall be forfeited and any vested Stock Appreciation Rights
shall be automatically redeemed. 
  

	8.	COVENANTS OF THE COMPANY. 

 (a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of shares of Common
Stock required to satisfy such Stock Awards. 
  

 12. 

 (b) Securities Law Compliance. The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this undertaking shall not require the
Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or
agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such
Stock Awards unless and until such authority is obtained. 
  

	9.	USE OF PROCEEDS FROM STOCK. 

 Proceeds from the sale of Common Stock pursuant to Stock Awards shall constitute general funds of the Company. 
  

	10.	MISCELLANEOUS. 

 (a) Acceleration
of Exercisability and Vesting. The Board shall have the power to accelerate the time at which a Stock Award may first be exercised or the time during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding
the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it will vest. 
 (b)
Stockholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Stock Award unless and until such Participant has satisfied all
requirements for exercise of the Stock Award pursuant to its terms. 
 (c) No Employment or other Service Rights. Nothing in the Plan
or any instrument executed or Stock Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the
right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the
Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case
may be. 
 (d) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time
of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars
($100,000), the Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of any Stock Award Agreement. 

 

 13. 

 (e) Investment Assurances. The Company may require a Participant, as a condition of exercising or
acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative
reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the
Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling
or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares of Common Stock upon the exercise or acquisition of Common
Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement
need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order
to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 
 (f)
Withholding Obligations. To the extent provided by the terms of a Stock Award Agreement, the Participant may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of Common Stock under a Stock
Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the
Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant as a result of the exercise or acquisition of Common Stock under the Stock Award; provided, however, that no shares of Common
Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid variable award accounting); or (iii) delivering to the Company owned and unencumbered shares
of Common Stock. 
  

	11.	ADJUSTMENTS UPON CHANGES IN STOCK. 

 (a) Capitalization Adjustments. If any change is made in, or other event occurs with respect to, the Common Stock subject to the Plan or subject to
any Stock Award without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend,
combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company (each a “Capitalization Adjustment”), the Plan will be appropriately adjusted in the
class(es) and maximum number of securities subject to the Plan pursuant to Sections 4(a) and 4(b) and the outstanding Stock Awards will be appropriately adjusted in the class(es) and number of securities and price per share of Common Stock subject
to such outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction “without
receipt of consideration” by the Company.) 
  

 14. 

 (b) Dissolution or Liquidation. In the event of a dissolution or liquidation of the Company, then
all outstanding Options shall terminate immediately prior to the completion of such dissolution or liquidation, and shares of Common Stock subject to the Company’s repurchase option may be repurchased by the Company notwithstanding the fact
that the holder of such stock in still in Continuous Service. 
 (c) Corporate Transaction. In the event of a Corporate Transaction,
any surviving corporation or acquiring corporation may assume or continue any or all Stock Awards outstanding under the Plan or may substitute similar stock awards for Stock Awards outstanding under the Plan (it being understood that similar stock
awards include, but are not limited to, awards to acquire the same consideration paid to the stockholders or the Company, as the case may be, pursuant to the Corporate Transaction), and any reacquisition or repurchase rights held by the Company in
respect of Common Stock issued pursuant to Stock Awards may be assigned by the Company to the successor of the Company (or such successor’s parent company), if any, in connection with such Corporate Transaction. In the event that any surviving
corporation or acquiring corporation does not assume or continue any or all such outstanding Stock Awards or substitute similar stock awards for such outstanding Stock Awards, then with respect to Stock Awards that have not been assumed, continued
or substituted and that are held by Participants whose Continuous Service has not terminated prior to the effective time of the Corporate Transaction, the vesting of such Stock Awards (and, if applicable, the time at which such Stock Awards may be
exercised) shall (contingent upon the effectiveness of the Corporate Transaction) be accelerated in full to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a
date, to the date that is five (5) days prior to the effective time of the Corporate Transaction), the Stock Awards shall terminate if not exercised (if applicable) at or prior to such effective time, and any reacquisition or repurchase rights
held by the Company with respect to such Stock Awards held by Participants whose Continuous Service has not terminated shall (contingent upon the effectiveness of the Corporate Transaction) lapse. With respect to any other Stock Awards outstanding
under the Plan that have not been assumed, continued or substituted, the vesting of such Stock Awards (and, if applicable, the time at which such Stock Award may be exercised) shall not be accelerated, unless otherwise provided in a written
agreement between the Company or any Affiliate and the holder of such Stock Award, and such Stock Awards shall terminate if not exercised (if applicable) prior to the effective time of the Corporate Transaction. 
 (d) Change in Control. A Stock Award held by any Participant whose Continuous Service has not terminated prior to the effective time of a Change
in Control may be subject to additional acceleration of vesting and exercisability upon or after such event as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company
or any Affiliate and the Participant, but in the absence of such provision, no such acceleration shall occur. 
  

	12.	AMENDMENT OF THE PLAN AND STOCK AWARDS. 

 (a) Amendment of Plan. The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 11(a) relating

 15. 

 (b) Stockholder Approval. The Board, in its sole discretion, may submit any other amendment to the
Plan for stockholder approval. 
 (c) Contemplated Amendments. It is expressly contemplated that the Board may amend the Plan in any

to bring the Plan and/or Incentive Stock Options granted under it into compliance therewith. 
 (d) No Impairment of Rights. Rights
under any Stock Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 
 (e) Amendment of Stock Awards. The Board at any time, and from time to time, may amend the terms of any one or more Stock Awards; provided,
however, that the rights under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 
  

	13.	TERMINATION OR SUSPENSION OF THE PLAN. 

 (a) Plan Term. The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate on the day before the
tenth (10th) anniversary of the date the Plan is adopted by the Board or approved by the stockholders of the Company, whichever is earlier. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated.

 (b) No Impairment of Rights. Suspension or termination of the Plan shall not impair rights and obligations under any Stock Award
granted while the Plan is in effect except with the written consent of the Participant. 
  

	14.	EFFECTIVE DATE OF PLAN. 

 The Plan shall become effective as determined by the Board, but no Stock Award shall be exercised (or, in the case of a stock bonus, shall be granted)
unless and until the Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board. 
  

	15.	CHOICE OF LAW.
