held by such Person, constitutes more than 50% of the total voting power of the stock of the Company, except that any change in the ownership of the stock of the Company as a result of a private financing of the Company that is approved by the Board

market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 

For purposes of this Section 2(f), persons will be considered to be acting as a group if they are owners of a corporation that

sole discretion.

follows: 
 (i) If the Common Stock is listed on any established stock exchange or a national market system, including without
limitation the Nasdaq Global Market, the Nasdaq Global Select Market or the Nasdaq Capital Market, its Fair Market Value shall be the closing sales price for such stock (or, if no closing sales price was reported on that date, as applicable, on the

If an Award expires or becomes unexercisable without having been exercised in full, or is surrendered pursuant to an Exchange Program,

returned to the Plan and shall not become available for future distribution under the Plan, except that if unvested Shares of Restricted Stock are repurchased by the Company at their original purchase price, such Shares shall become available for
future grant under the Plan. Notwithstanding the foregoing and, subject to adjustment provided in Section 11, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options shall equal the aggregate Share number

 -5-








 6. Stock Options. 

(a) Term of Option. The term of each Option shall be stated in the Award Agreement; provided, however, that the term shall be no
more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to a Participant who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 

(b) Option Exercise Price and Consideration. 
 (i) Exercise Price. The per share exercise price for the Shares to be issued upon exercise of an Option shall be such price as is determined by the Administrator, but shall be subject to the
following: 
 (A) In the case of an Incentive Stock Option 

a) granted to an Employee who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than one hundred and ten percent (110%) of the Fair Market Value per Share on the date of grant. 

b) granted to any other Employee, the per Share exercise price shall be no less than one hundred percent (100%) of the Fair Market
Value per Share on the date of grant. 
 (B) In the case of a Nonstatutory Stock Option, the per Share exercise price shall be
no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (C) Notwithstanding
the foregoing, Options may be granted with a per Share exercise price other than as required above in accordance with and pursuant to a transaction described in Section 424 of the Code. 

(ii) Forms of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the
method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant). Such consideration may consist of, without limitation, (1) cash, (2) check,
(3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option
shall be exercised and provided that accepting such Shares, in the sole discretion of the Administrator, shall not result in any adverse accounting consequences to the Company, (5) consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan, (6) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws, or (7) any combination of the foregoing methods of
payment. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company. 

  
 -6-








 (c) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable according to the terms
hereof at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option shall be deemed exercised when the Company receives (i) written or electronic notice of exercise (in accordance with the
Award Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised, together with any applicable withholding taxes. Full payment may consist of any consideration
and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Participant or, if requested by the Participant, in the name of the
Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to the Shares, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment shall be made for a dividend or other
right for which the record date is prior to the date the Shares are issued, except as provided in Section 11 of the Plan. 

Exercise of an Option in any manner shall result in a decrease in the number of Shares thereafter available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (ii) Termination of
Relationship as a Service Provider. If a Participant ceases to be a Service Provider, such Participant may exercise his or her Option within such period of time as is specified in the Award Agreement, to the extent that the Option is vested on
the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for three
(3) months following the Participant’s termination. Unless the Administrator provides otherwise, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Participant does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

 (iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the
Participant’s Disability, the Participant may exercise his or her Option within such longer period of time as is specified in the Award Agreement, to the extent the Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for twelve (12) months following the Participant’s termination.
Unless the Administrator provides otherwise, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the
Participant does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 

  
 -7-








 (iv) Death of Participant. If a Participant dies while a Service Provider, the
Option may be exercised within such longer period of time as is specified in the Award Agreement, to the extent that the Option is vested on the date of death (but in no event later than the expiration of the term of such Option as set forth in the
Award Agreement) by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to the Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the
Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent
and distribution. In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for twelve (12) months following the Participant’s termination. If, at the time of death, the Participant is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan. 
 (v) Incentive Stock Option Limit. Each Option shall be designated in the Award
Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable
for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options shall be treated as Nonstatutory Stock Options. For purposes
of this Section 6(c)(v), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted.

 7. Restricted Stock. 
 (a) Rights to Purchase. Restricted Stock may be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the
Administrator determines that it shall offer Restricted Stock under the Plan, it shall advise the offeree in writing or electronically of the terms, conditions and restrictions related to the offer, including the number of Shares that such person
shall be entitled to purchase, the price to be paid (if any), and the time within which such person must accept such offer. 

(b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the
Company a repurchase option exercisable within ninety (90) days of the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or Disability). Unless the Administrator provides
otherwise, the purchase price for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The
repurchase option shall lapse at such rate as the Administrator may determine. 

  
 -8-








 (c) Other Provisions. The Restricted Stock Purchase Agreement shall contain such
other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 (d) Rights as a Stockholder. Once the Restricted Stock is purchased or otherwise issued, the purchaser shall have rights equivalent to those of a stockholder and shall be a stockholder when his or
her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Restricted Stock is purchased or otherwise
issued, except as provided in Section 11 of the Plan. 
 8. Tax Withholding. Prior to the delivery of any Shares
pursuant to an Award (or exercise thereof), the Company shall have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes
(including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise thereof). The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, shall
determine in what manner it shall allow a Participant to satisfy such tax withholding obligation and may permit the Participant to satisfy such tax withholding obligation, in whole or in part by one (1) or more of the following: (a) paying
cash (or by check), (b) electing to have the Company withhold otherwise deliverable Shares having a Fair Market Value equal to the minimum amount statutorily required to be withheld, or (c) selling a sufficient number of such Shares
otherwise deliverable to a Participant through such means as the Company may determine in its sole discretion (whether through a broker or otherwise) equal to the minimum amount statutorily required to be withheld. 

9. Limited Transferability of Awards. Unless determined otherwise by the Administrator, Awards may not be sold, pledged, assigned,
hypothecated, transferred, or disposed of in any manner other than by will or the laws of descent and distribution, and may be exercised during the lifetime of the Participant, only by the Participant. 

10. Leaves of Absence; Transfers. 
 (a) Unless the Administrator provides otherwise, or except as otherwise required by Applicable Laws, vesting of Awards granted hereunder shall be suspended during any unpaid leave of absence. 

(b) A Service Provider shall not cease to be a Service Provider in the case of (i) any leave of absence approved by the Company, or
(ii) transfers between locations of the Company or between the Company, its Parent, any Subsidiary, or any successor. 

(c) For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such
leave is guaranteed by statute or 

  
 -9-








 
contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then six (6) months following the first (1st) day of such leave, any Incentive Stock Option held by the
Participant shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory Stock Option. 
 11. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or
other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate
structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, shall adjust the number and class of Shares
that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award. 
 (b)
Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent
it has not been previously exercised, an Award shall terminate immediately prior to the consummation of such proposed action. 

(c) Merger or Change in Control. In the event of a merger or Change in Control, each outstanding Award shall be treated as the
Administrator determines, including, without limitation, that each Award be assumed or an equivalent award substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Administrator shall not be required to
treat all Awards similarly in the transaction. 
 Notwithstanding the foregoing, in the event of a Change in Control in which
the successor corporation does not assume or substitute for the Award, the Participant shall fully vest in and have the right to exercise his or her outstanding Awards, including Shares as to which such Award would not otherwise be vested or
exercisable, and restrictions on all of the Participant’s Restricted Stock shall lapse. In addition, if an Award is not assumed or substituted in the event of a merger or Change in Control, the Administrator shall notify the Participant in
writing or electronically that the Award shall be fully vested and exercisable for a period of time determined by the Administrator in its sole discretion, and any Award not assumed or substituted for shall terminate upon the expiration of such
period for no consideration, unless otherwise determined by the Administrator. 
 For the purposes of this Section 11(c),
the Award shall be considered assumed if, following the merger or Change in Control, the option or right confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in Control, the
consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, 

  
 -10-








 
however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of
the successor corporation, provide for the consideration to be received upon the exercise of the Award, for each Share subject to the Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per
share consideration received by holders of common stock in the merger or Change in Control. 
 12. Time of Granting
Awards. The date of grant of an Award shall, for all purposes, be the date on which the Administrator makes the determination granting such Award, or such later date as is determined by the Administrator. Notice of the determination shall be
given to each Service Provider to whom an Award is so granted within a reasonable time after the date of such grant. 
 13.
No Effect on Employment or Service. Neither the Plan nor any Award shall confer upon any participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company, nor shall it interfere in
any way with his or her right or the Company’s right to terminate such relationship at any time, with or without cause, and with or without notice. 
 14. Conditions Upon Issuance of Shares. 
 (a) Legal Compliance.
Shares shall not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company
with respect to such compliance. 
 (b) Investment Representations. As a condition to the exercise of an Award, the
Administrator may in its discretion require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute
such Shares. 
 15. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained. 
 16. Reservation of Shares. The Company,
during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
 17. Stockholder Approval. The Plan shall be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted. Such stockholder approval shall
be obtained in the degree and manner required under Applicable Laws. 

  
 -11-








 18. Term of Plan. Subject to stockholder approval in accordance with
Section 17, the Plan shall become effective upon its adoption by the Board. Unless sooner terminated under Section 19, it shall continue in effect for a term of ten (10) years from the later of (a) the effective date of the Plan,
or (b) the earlier of the most recent Board or stockholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 19. Amendment and Termination of the Plan. 
 (a) Amendment and
Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 
 (b) Stockholder Approval. The
Board shall obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Participant, unless mutually agreed otherwise between the
Participant and the Administrator, which agreement must be in writing (which may include e-mail) and signed by the Participant and the Company. Termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted
to it hereunder with respect to Options granted under the Plan prior to the date of such termination.

accordance with the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for twelve (12) months following the
Participant’s termination. 
 (f) No Award shall be granted to a resident of California more than ten (10) years after
the earlier of the date of adoption of the Plan or the date the Plan is approved by the stockholders.

exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits
intended to be made available under the Plan, shall adjust the number and class of shares of common stock that may be delivered under the Plan and/or the number, class, and price of shares covered by each outstanding Option. The Administrator shall
also make such adjustments to the extent required by Section 25102(o) of the California Corporations Code.

		  	Incentive Stock Option
		
	Term / Expiration Date:	  	[                    ]

 Subject to Section 19(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and
this Option Agreement, the terms and conditions of the Nan shall prevail. 
 2. Vesting Schedule. This Option shall
become exercisable, and Participant shall be entitled to purchase a percentage of the Shares in accordance with the following vesting schedule: 
 (a) This Option shall become exercisable with respect to twenty-five percent (25%) of the Shares on the one (1) year anniversary of the Vesting Commencement Date, subject to Participant
continuing to be a Service Provider through such date, and 
 (b) This Option shall become exercisable with
respect to an additional one forth-eighth (1/48th) of
the Shares on the last day of each month following the one (1) year anniversary of the Vesting Commencement Date, subject to Participant continuing to be a Service Provider through each such date. 






 3. Exercise of Option. 

(a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set forth in
Section 1.2 above and with the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of
Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which
shall state that Participant has elected to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be

accompanied by the aggregate Exercise Price, together with any applicable tax withholding. 
 No Shares shall be issued pursuant

with respect to such Shares.

	II.	OTHER TERMS 

 1.
Option. If this Option has been designated in the Stock Option Notice as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to
the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further, if for any reason this Option (or portion thereof) shall not qualify as an ISO, then,
to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator, the Company or any Parent or Subsidiary or any of their respective employees or
directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 2. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, Participant shall, if
required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B. 

3. Lock-Up Period. Participant hereby agrees that Participant shall not offer, pledge, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to 

  
 2 







 
sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any
swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by Participant (other than those included in the
registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and eighty (180) days following the effective date of any registration statement of
the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and
(ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(0(4) or NYSE Rule 4720(4), or any successor provisions or amendments thereto). 

Participant agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which
are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Participant shall
provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration
statement filed under the Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or
a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other
securities) subject to the foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this
Section 3. 
 4. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a
combination thereof, at the election of the Participant: 
 (a) cash; 

(b) check; 

(c) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or

 (d) surrender of other Shares which (i) shall be valued at its Fair Market Value on the date of exercise, and
(ii) must be owned free and clear of any liens, claims, encumbrances or security interests, if accepting such Shares, in the sole discretion of the Administrator, shall not result in any adverse accounting consequences to the Company.

 5. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the
stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 

  
 3 







 6. Non-Transferability of Option. This Option may not be transferred in any manner
otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs,
successors and assigns of Participant. 
 7. Term of Option. This Option may be exercised only within the term set out in
the Stock Option Notice, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 

8. Tax Obligations. 
 (a) Tax Withholding. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Federal,
state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding
amounts are not delivered at the time of exercise. 
 (b) Notice of Disqualifying Disposition of ISO Shares. If the
Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, or (ii) the
date one (1) year after the date of exercise, Participant shall immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation
income recognized by Participant. 
 (c) Code Section 409A. Under Code Section 409A, an Option that vests after
December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the Internal Revenue Service (the “IRS”)
to be less than the Fair Market Value of a Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount option” may result in (i) income recognition by
Participant prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. 
 The “discount option” may also result in additional state income, penalty and interest tax to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the
IRS will agree that the per Share exercise price of this Option equals or exceeds the Fair Market Value of a Share on the date of grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per
Share exercise price that was less than the Fair Market Value of a Share on the date of grant, Participant shall be solely responsible for Participant’s costs related to such a determination. 

9. Entire Agreement; Governing_ Law. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute
the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of 

  
 4 







 
the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and
Participant. This Agreement is governed by the internal substantive laws but not the choice of law rules of the State of Delaware. 
 10. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT
THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS
AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT
CAUSE. 
 Participant acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and
provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing
this Option and fully understands all provisions of the Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option.
Participant further agrees to notify the Company upon any change in the residence address indicated below.

Attention: President 
  

	 	1.	Exercise of Option. Effective as of the date set forth below,
[                    ] (“Participant”) hereby elects to exercise Participant’s option (the “Option”) to purchase shares of
the Class B Non-Voting Common Stock (the “Shares”), of Model Metrics, Inc. (the “Company”) under and pursuant to the 2008 Stock Plan (the “Plan”) and the Stock Option Agreement dated
[                    ] (the “Option Agreement”). 


 

	 	2.	Delivery of Payment. Participant herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any and all
withholding taxes due in connection with the exercise of the Option. 

  

	 	3.	Representations of Participant. Participant acknowledges that Participant has received, read and understood the Plan and the Option Agreement and agrees to abide
by and be bound by their terms and conditions. 

  

	 	4.	Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent
of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the exercise of the Option. The Shares shall be issued to Participant as
soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as provided in Section 11 of
the Plan. 

  

	 	5.	Company’s Right of First Refusal. Before any Shares held by Participant or any transferee (either being sometimes referred to herein as the
“Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this
Section 5 (the “Right of First Refusal”). 

  

	 	a.	Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the
Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed
Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its
assignee(s). 


  
 6 








	 	b.	Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving
written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (c) below.


  

	 	c.	Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 5 shall be the
Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 


 

	 	d.	Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of
any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set
forth in the Notice. 

  

	 	e.	Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company
and/or its assignee(s) as provided in this Section 5, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the
provisions of this Section 5 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to
the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 


 

	 	f.	Exception for Certain Family Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer of any or all of the Shares
during the Participant’s lifetime or on the Participant’s death by will or intestacy to the Participant’s immediate family or a trust for the benefit of the Participant’s immediate family shall be exempt from the provisions of
this Section 5. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section 5, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 5. 


  
 7 








	 	g.	Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the first sale of Common Stock of
the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

  

	 	6.	Drag Along Right. In the event that the Board of Directors of the Company notifies Participant that it has approved a Sale of the Company (as defined below),
then Participant shall do the following: 

  

	 	a.	if such transaction requires stockholder approval, with respect to all Shares that such Stockholder owns or over which such Stockholder otherwise exercises voting
power, to vote (in person, by proxy or by action by written consent, as applicable) all Shares in favor of, and adopt, such Sale of the Company (together with any related amendment to the Company’s Certificate of Incorporation required in order
to implement such Sale of the Company) and to vote in opposition to any and all other proposals that could reasonably be expected to delay or impair the ability of the Company to consummate such Sale of the Company; 


 

	 	b.	if such transaction is sale of the capital stock of the Company, to sell the same proportion of shares of capital stock of the Company beneficially held by Participant
as is being sold by the Company’s selling stockholder to the Person to whom such selling stockholders propose to sell their capital stock, and, except as permitted below, on the same terms and conditions as the selling stockholders;


  

	 	c.	to execute and deliver all related documentation and take such other action in support of the Sale of the Company as shall reasonably be requested by the Company in
order to carry out the terms and provision of this section, including without limitation executing and delivering instruments of conveyance and transfer, and any purchase agreement, merger agreement, indemnity agreement, escrow agreement, consent,
waiver, governmental filing, share certificates duly endorsed for transfer (free and clear of impermissible liens, claims and encumbrances) and any similar or related documents; 


 

	 	d.	not to deposit any Shares in a voting trust or subject any Shares to any arrangement or agreement with respect to the voting of such Shares, unless specifically
requested to do so by the acquiror in connection with the Sale of the Company; 

  

	 	e.	 to refrain from exercising any dissenters’ rights or rights of appraisal under applicable law at any time with respect to such Sale of the
Company; if the consideration to be paid in exchange for the Shares pursuant to the Sale of the Company includes any securities and due receipt thereof by any stockholder would require under applicable law
(x)



  
 8 








	 	
the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities or (y) the provision to any stockholder of any
information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act of 1933, as amended, the Company may
cause to be paid to any such stockholder in lieu thereof, against surrender of the Shares which would have otherwise been sold by Participant, an amount in cash equal to the fair value (as determined in good faith by the Company) of the securities
which Participant would otherwise receive as of the date of the issuance of such securities in exchange for the Shares; and 

  

	 	f.	for purposes of this Section, “Sale of the Company” shall mean: (i) a transaction or series of related transactions in which a third-party(ies)
acquires from stockholders of the Company shares representing a majority of the outstanding voting power of the Company; (ii) the sate of all or substantially all the Company’s assets in one or a series of related transactions; or
(iii) a merger, consolidation or other transaction in which the stockholders of the Company immediately prior to such transaction do not represent immediately following such transaction a majority of the voting power of the surviving entity.


  

	 	7.	Tax Consultation. Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s purchase or disposition of the
Shares. Participant represents that Participant has consulted with any tax consultants Participant deems advisable in connection with the purchase or disposition of the Shares and that Participant is not relying on the Company for any tax advice.


  

	 	8.	Restrictive Legends and Stop-Transfer Orders. 

  

	 	a.	Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially equivalent thereto, to be placed
upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 


THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED,
SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH.

	 	b.	Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate
“stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

	SECURITY	  	    CLASS B NON-VOTING COMMON STOCK
		
	AMOUNT	  	
		
	DATE	  	

 In connection with the purchase of the above-listed Securities, the undersigned Participant represents to
the Company the following: 
 (a) Participant is aware of the Company’s business affairs and financial condition and has
acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not with a view to, or
for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance
upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this connection, Participant understands that, in the view of the Securities
and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in the future. Participant further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and understands that the Company is under no obligation to register the Securities.
Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 
 (c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities”
acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to
Participant, the exercise shall be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days
thereafter (or such longer period as any market stand-off agreement may require) the 






 
Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an
unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public
information about the Company, (3) the amount of Securities being sold during any three (3) month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable. 

In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one (1) year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an
affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two (2) years, the satisfaction of the conditions
set forth in sections (1), (2), (3) and (4) of the paragraph immediately above. 
 (d) Participant further understands
that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that, notwithstanding the
fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant
to Rules 144 or 701 shall have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at
their own risk. Participant understands that no assurances can be given that any such other registration exemption shall be available in such event.
