provide additional incentives to Employees, Directors and Consultants and to promote the success of the Company’s business. 

2.     Definitions. The following definitions shall apply as used herein and in the individual Award Agreements
except as defined otherwise in an individual Award Agreement. In the event a term is separately defined in an individual Award Agreement, such definition shall supersede the definition contained in this Section 2. 

(a)     “Administrator” means the Board or any of the Committees appointed to administer the Plan. 

(b)     “Applicable Laws” means the legal requirements relating to the Plan and the Awards under
applicable provisions of federal and state securities laws, the corporate laws of California, and to the extent other than California, the corporate law of the state of the Company’s incorporation, the Code, the rules of any applicable stock
exchange or national market system, and the rules of any non-U.S. jurisdiction applicable to Awards granted to residents therein. 

(c)     “Assumed” means that pursuant to a Corporate Transaction either (i) the Award is expressly
affirmed by the Company or (ii) the contractual obligations represented by the Award are expressly assumed (and not simply by operation of law) by the successor entity or its Parent in connection with the Corporate Transaction with appropriate
adjustments to the number and type of securities of the successor entity or its Parent subject to the Award and the exercise or purchase price thereof which at least preserves the compensation element of the Award existing at the time of the
Corporate Transaction as determined in accordance with the instruments evidencing the agreement to assume the Award. 

(d)     “Award” means the grant of an Option, SAR, Dividend Equivalent Right, Restricted Stock,
Restricted Stock Unit or other right or benefit under the Plan.

written agreement evidencing the grant of an Award executed by the Company and the Grantee, including any amendments thereto. 

(f)     “Board” means the Board of Directors of the Company. 

(g)     “Cause” means, with respect to the termination by the Company or a Related Entity of the
Grantee’s Continuous Service, that such termination is for “Cause” as such term (or word of like import) is expressly defined in a then-effective written agreement between the Grantee and the Company or such Related Entity, or in the
absence of such then-effective written agreement and definition, is based on, in the determination of the Administrator, the Grantee’s: (i) performance of any act or failure to perform any act in bad faith and to the detriment of the
Company or a Related Entity; (ii) dishonesty, intentional misconduct or material breach of any agreement with the Company or a Related Entity; or (iii) commission of a crime involving dishonesty, breach of trust, or physical or emotional

a Related Entity in any capacity of Employee, Director or Consultant is not interrupted or terminated. In jurisdictions requiring notice in advance of an effective termination as an Employee, Director or Consultant, Continuous Service shall be
deemed terminated upon the actual cessation of providing services to the Company or a Related Entity notwithstanding any required notice period that must be fulfilled before a termination as an Employee, Director or Consultant can be effective under
Applicable Laws. A Grantee’s Continuous Service shall be deemed to have terminated either upon an actual termination of Continuous Service or upon the entity for which the Grantee provides services ceasing to be a Related Entity. Continuous
Service shall not be considered interrupted in the case of (i) any approved leave of absence, (ii) transfers among the Company, any Related Entity, or any successor, in any capacity of Employee, Director or Consultant, or (iii) any
change in status as long as the individual remains in the service of the Company or a Related Entity in any capacity of Employee, Director or Consultant (except as otherwise provided in the Award Agreement). Notwithstanding the foregoing, except as
otherwise determined by the Administrator, in the event of any spin-off of a Related Entity, service as an Employee, Director or Consultant for such Related Entity following such
spin-off shall be deemed to be Continuous Service for purposes of the Plan and any Award under the Plan. An approved leave of absence shall include sick leave, military leave, or any other authorized personal
leave. For purposes of each Incentive Stock Option granted under the Plan, if such leave exceeds three (3) months, and reemployment upon expiration of such leave is not guaranteed by statute or contract, then the Incentive Stock Option shall be
treated as a Non-Qualified Stock Option on the day three (3) months and one (1) day following the expiration of such three (3) month period.

long-term disability plan in place, “Disability” means that a Grantee is unable to carry out the responsibilities and functions of the position held by the Grantee by reason of any medically determinable physical or mental impairment for a

(ii)     If the Common Stock is regularly quoted on an automated quotation system (including the OTC Bulletin Board) or
by a recognized securities dealer, its Fair Market Value shall be the closing sales price for such stock as quoted on such system or by such securities dealer on the date of determination, but if selling prices are not reported, the Fair Market
Value of a share of Common Stock shall be the mean between the high bid and low asked prices for the Common Stock on the date of determination (or, if no such prices were reported on that date, on the last date such prices were reported), as
reported in The Wall Street Journal or such other source as the Administrator deems reliable; or 
 (iii)     In the
absence of an established market for the Common Stock of the type described in (i) and (ii), above, the Fair Market Value thereof shall be determined by the Administrator in good faith and in a manner consistent with Applicable

 4.     Administration of the Plan. 

(a)     Plan Administrator.     

(i)     Administration with Respect to Directors and Officers. Prior to the Registration Date, with respect to
grants of Awards to Directors or Employees who are also Officers or Directors of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner
as to satisfy the Applicable Laws. On or after the Registration Date, with respect to grants of Awards to Directors or Employees who are also Officers or Directors of the Company, the Plan shall be administered by (A) the Board or (B) a
Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws and to permit such grants and related transactions under the Plan to be exempt from Section 16(b) of the Exchange Act in
accordance with Rule 16b-3. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. 

(ii)     Administration With Respect to Consultants and Other Employees. With respect to grants of Awards to
Employees or Consultants who are neither Directors nor Officers of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy
the Applicable Laws. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. 

(iii)     Administration With Respect to Covered Employees. Notwithstanding the foregoing, as of and after the
date that the exemption for the Plan under Section 162(m) of the Code expires, as set forth in Section 19 below, grants of Awards to any Covered Employee intended to qualify as Performance-Based Compensation shall be made only by a
Committee (or subcommittee of a Committee) which is comprised solely of two or more Directors eligible to serve on a committee making Awards qualifying as Performance-Based Compensation. In the case of such Awards granted to Covered Employees,
references to the “Administrator” or to a “Committee” shall be deemed to be references to such Committee or subcommittee. 

(b)     Multiple Administrative Bodies. The Plan may be administered by different bodies with respect to Directors,
Officers, Consultants, and Employees who are neither Directors nor Officers. 
 (c)     Powers of the
Administrator. Subject to Applicable Laws and the provisions of the Plan (including any other powers given to the Administrator hereunder), and except as otherwise provided by the Board, the Administrator shall have the authority, in its
discretion: 
 (i)     to select the Employees, Directors and Consultants to whom Awards may be granted from time to
time hereunder; 
 (ii)     to determine whether and to what extent Awards are granted hereunder; 

  
 7 













 (iii)     to determine the number of Shares or the amount of other
consideration to be covered by each Award granted hereunder; 
 (iv)     to approve forms of Award Agreements for use
under the Plan; 
 (v)     to determine the terms and conditions of any Award granted hereunder; 

(vi)     to establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable non-U.S. jurisdictions and to afford Grantees favorable treatment under such rules or laws; provided, however, that no Award shall be granted under any such additional terms, conditions, rules or procedures with
terms or conditions which are inconsistent with the provisions of the Plan; 
 (vii)     to amend the terms of any
outstanding Award granted under the Plan, provided that any amendment that would adversely affect the Grantee’s rights under an outstanding Award shall not be made without the Grantee’s written consent, provided, however, that an amendment
or modification that may cause an Incentive Stock Option to become a Non-Qualified Stock Option shall not be treated as adversely affecting the rights of the Grantee. Notwithstanding the foregoing,
(A) the reduction or increase of the exercise price of any Option awarded under the Plan and the base appreciation amount of any SAR awarded under the Plan and (B) canceling an Option or SAR at a time when its exercise price or base
appreciation amount (as applicable) exceeds the Fair Market Value of the underlying Shares, in exchange for another Option, SAR, Restricted Stock, or other Award, in each case, shall not be subject to stockholder approval; 

(viii)     to construe and interpret the terms of the Plan and Awards, including without limitation, any notice of award
or Award Agreement, granted pursuant to the Plan; and 
 (ix)     to take such other action, not inconsistent with the
terms of the Plan, as the Administrator deems appropriate. 
 The express grant in the Plan of any specific power to the Administrator shall not be
construed as limiting any power or authority of the Administrator; provided that the Administrator may not exercise any right or power reserved to the Board. Any decision made, or action taken, by the Administrator or in connection with the
administration of this Plan shall be final, conclusive and binding on all persons having an interest in the Plan. 

(d)     Indemnification. In addition to such other rights of indemnification as they may have as members of the
Board or as Officers or Employees of the Company or a Related Entity, members of the Board and any Officers or Employees of the Company or a Related Entity to whom authority to act for the Board, the Administrator or the Company is delegated shall
be defended and indemnified by the Company to the extent permitted by law on an after-tax basis against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection
with the defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or
any Award granted 

  
 8 













 
hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by the Company) or paid by them in satisfaction of a judgment in any such claim,
investigation, action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such claim, investigation, action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct;
provided, however, that within thirty (30) days after the institution of such claim, investigation, action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at the Company’s expense to defend the
same. 
 5.     Eligibility. Awards other than Incentive Stock Options may be granted to Employees, Directors and
Consultants. Incentive Stock Options may be granted only to Employees of the Company or a Parent or a Subsidiary of the Company. An Employee, Director or Consultant who has been granted an Award may, if otherwise eligible, be granted additional
Awards. Awards may be granted to such Employees, Directors or Consultants who are residing in non-U.S. jurisdictions as the Administrator may determine from time to time. 

6.     Terms and Conditions of Awards. 

(a)     Types of Awards. The Administrator is authorized under the Plan to award any type of arrangement to an
Employee, Director or Consultant that is not inconsistent with the provisions of the Plan and that by its terms involves or might involve the issuance of (i) Shares, (ii) cash or (iii) an Option, a SAR, or similar right with a fixed or
variable price related to the Fair Market Value of the Shares and with an exercise or conversion privilege related to the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions. Such
awards include, without limitation, Options, SARs, sales or bonuses of Restricted Stock, Restricted Stock Units or Dividend Equivalent Rights, and an Award may consist of one such security or benefit, or two (2) or more of them in any
combination or alternative. 
 (b)     Designation of Award. Each Award shall be designated in the Award
Agreement. In the case of an Option, the Option shall be designated as either an Incentive Stock Option or a Non-Qualified Stock Option. However, notwithstanding such designation, an Option will qualify as an
Incentive Stock Option under the Code only to the extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. The $100,000 limitation of Section 422(d) of the Code is calculated based on the aggregate Fair Market
Value of the Shares subject to Options designated as Incentive Stock Options which become exercisable for the first time by a Grantee during any calendar year (under all plans of the Company or any Parent or Subsidiary of the Company). For purposes
of this calculation, Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the grant date of the relevant Option. In the event that the Code or
the regulations promulgated thereunder are amended after the date the Plan becomes effective to provide for a different limit on the Fair Market Value of Shares permitted to be subject to Incentive Stock Options, then such different limit will be
automatically incorporated herein and will apply to any Options granted after the effective date of such amendment. 

(c)     Conditions of Award. Subject to the terms of the Plan, the Administrator shall determine the provisions,
terms, and conditions of each Award including, but not limited to, the Award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, 

  
 9 













 
form of payment (cash, Shares, or other consideration) upon settlement of the Award, payment contingencies, and satisfaction of any performance criteria. The performance criteria established by
the Administrator may be based on any one of, or combination of, increase in share price, earnings per share, total stockholder return, return on equity, return on assets, return on investment, net operating income, cash flow, revenue, economic
value added, personal management objectives, or other measure of performance selected by the Administrator. Partial achievement of the specified criteria may result in a payment or vesting corresponding to the degree of achievement as specified in
the Award Agreement. In addition, the performance criteria shall be calculated in accordance with generally accepted accounting principles, but excluding the effect (whether positive or negative) of any change in accounting standards and any
extraordinary, unusual or nonrecurring item, as determined by the Administrator, occurring after the establishment of the performance criteria applicable to the Award intended to be performance-based compensation. Each such adjustment, if any, shall
be made solely for the purpose of providing a consistent basis from period to period for the calculation of performance criteria in order to prevent the dilution or enlargement of the Grantee’s rights with respect to an Award intended to be
performance-based compensation. 
 (d)     Acquisitions and Other Transactions. The Administrator may issue
Awards under the Plan in settlement, assumption or substitution for, outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring another entity, an interest in another entity or an additional
interest in a Related Entity whether by merger, stock purchase, asset purchase or other form of transaction. 
 (e)    
Deferral of Award Payment. The Administrator may establish one or more programs under the Plan to permit selected Grantees the opportunity to elect to defer receipt of consideration upon exercise of an Award, satisfaction of performance
criteria, or other event that absent the election would entitle the Grantee to payment or receipt of Shares or other consideration under an Award. The Administrator may establish the election procedures, the timing of such elections, the mechanisms
for payments of, and accrual of interest or other earnings, if any, on amounts, Shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any
such deferral program. 
 (f)     Separate Programs. The Administrator may establish one or more separate
programs under the Plan for the purpose of issuing particular forms of Awards to one or more classes of Grantees on such terms and conditions as determined by the Administrator from time to time. 

(g)     Individual Limitations on Awards. 

(i)     Individual Option and SAR Limit. Following the date that the exemption from application of
Section 162(m) of the Code described in Section 19 (or any exemption having similar effect) ceases to apply to Awards, the maximum number of Shares with respect to which Options and SARs may be granted to any Grantee in any calendar year
shall be 666,178 Shares. The foregoing limitations shall be adjusted proportionately in connection with any change in the Company’s capitalization pursuant to Section 10, below. To the extent required by Section 162(m) of the Code or
the regulations thereunder, in applying the foregoing limitations with respect to a Grantee, if any Option or SAR is canceled, the canceled 

  
 10 













 
Option or SAR shall continue to count against the maximum number of Shares with respect to which Options and SARs may be granted to the Grantee. For this purpose, the repricing of an Option (or
in the case of a SAR, the base amount on which the stock appreciation is calculated is reduced to reflect a reduction in the Fair Market Value of the Common Stock) shall be treated as the cancellation of the existing Option or SAR and the grant of a
new Option or SAR. 
 (ii)     Individual Limit for Restricted Stock and Restricted Stock Units. Following the
date that the exemption from application of Section 162(m) of the Code described in Section 19 (or any exemption having similar effect) ceases to apply to Awards, for awards of Restricted Stock and Restricted Stock Units that are intended
to be Performance-Based Compensation, the maximum number of Shares with respect to which such Awards may be granted to any Grantee in any calendar year shall be 666,178 Shares. The foregoing limitation shall be adjusted proportionately in connection
with any change in the Company’s capitalization pursuant to Section 10, below. 
 (h)     Early
Exercise. The Award Agreement may, but need not, include a provision whereby the Grantee may elect at any time while an Employee, Director or Consultant to exercise any part or all of the Award prior to full vesting of the Award. Any unvested
Shares received pursuant to such exercise may be subject to a repurchase right in favor of the Company or a Related Entity or to any other restriction the Administrator determines to be appropriate. 

(i)     Term of Award. The term of each Award shall be the term stated in the Award Agreement, provided, however,
that the term shall be no more than ten (10) years from the date of grant thereof. However, in the case of an Incentive Stock Option granted to a Grantee 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 of the Company, the term of the Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided
in the Award Agreement. Notwithstanding the foregoing, the specified term of any Award shall not include any period for which the Grantee has elected to defer the receipt of the Shares or cash issuable pursuant to the Award. 

(j)     Transferability of Awards. Incentive Stock Options may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Grantee, only by the Grantee. Other Awards shall be transferable (i) by will and by the laws
of descent and distribution and (ii) during the lifetime of the Grantee, to the extent and in the manner authorized by the Administrator by gift or pursuant to a domestic relations order to members of the Grantee’s Immediate Family.
Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Award in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator. 

(k)     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 to grant such Award, or such other later date as is determined by the Administrator. 

  
 11 













 7.     Award Exercise or Purchase Price, Consideration and Taxes.

 (a)     Exercise or Purchase Price. The exercise or purchase price, if any, for an Award shall be as follows:

 (i)     In the case of an Incentive Stock Option: 

(A)     granted to an Employee who, at the time of the grant of such Incentive Stock 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 of the Company, the per Share exercise price shall be not less than one hundred ten percent (110%) of the Fair Market Value per Share on
the date of grant; or 
 (B)     granted to any Employee other than an Employee described in the preceding paragraph,
the per Share exercise price shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(ii)     In the case of a Non-Qualified Stock Option, the per Share exercise
price shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(iii)     In the case of SARs, the base appreciation amount shall not be less than one hundred percent (100%) of the Fair
Market Value per Share on the date of grant. 
 (iv)     In the case of Awards intended to qualify as Performance-Based
Compensation, the exercise or purchase price, if any, shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(v)     In the case of the sale of Shares, the per Share purchase price, if any, shall be such price as is determined by
the Administrator. 
 (vi)     In the case of other Awards, such price as is determined by the Administrator. 

(vii)     Notwithstanding the foregoing provisions of this Section 7(a), in the case of an Award issued pursuant to
Section 6(d), above, the exercise or purchase price for the Award shall be determined in accordance with the provisions of the relevant instrument evidencing the agreement to issue such Award. 

(b)     Consideration. Subject to Applicable Laws, the consideration to be paid for the Shares to be issued upon
exercise or purchase of an Award including the method of payment, shall be determined by the Administrator. In addition to any other types of consideration the Administrator may determine, the Administrator is authorized to accept as consideration
for Shares issued under the Plan the following provided that the portion of the consideration equal to the par value of the Shares must be paid in cash or other legal consideration permitted by the Delaware General Corporation Law: 

(i)     cash; 

  
 12 













 (ii)     check; 

(iii)     delivery of Grantee’s promissory note with such recourse, interest, security, and redemption provisions as
the Administrator determines as appropriate (but only to the extent that the acceptance or terms of the promissory note would not violate an Applicable Law); 

(iv)     surrender of Shares held for the requisite period, if any, necessary to avoid a charge to the Company’s
earnings for financial reporting purposes, or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require which have a Fair Market Value on the date of surrender or attestation equal to the aggregate
exercise price of the Shares as to which said Award shall be exercised; 
 (v)     with respect to Options, if the
exercise occurs on or after the Registration Date, payment through a broker-dealer sale and remittance procedure pursuant to which the Grantee (A) shall provide written instructions to a Company designated brokerage firm to effect the immediate
sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate exercise price payable for the purchased Shares and (B) shall provide written directives to the Company to deliver the certificates for
the purchased Shares directly to such brokerage firm in order to complete the sale transaction; 
 (vi)     with
respect to Options, payment through a “net exercise” such that, without the payment of any funds, the Grantee may exercise the Option and receive the net number of Shares equal to (i) the number of Shares as to which the Option is
being exercised, multiplied by (ii) a fraction, the numerator of which is the Fair Market Value per Share (on such date as is determined by the Administrator) less the exercise price per Share, and the denominator of which is such Fair Market
Value per Share (the number of net Shares to be received shall be rounded down to the nearest whole number of Shares); or 

(vii)     any combination of the foregoing methods of payment. 

The Administrator may at any time or from time to time, by adoption of or by amendment to the standard forms of Award Agreement described in
Section 4(c)(iv), or by other means, grant Awards which do not permit all of the foregoing forms of consideration to be used in payment for the Shares or which otherwise restrict one or more forms of consideration. 

(c)     Taxes. No Shares shall be delivered under the Plan to any Grantee or other person until such Grantee or
other person has made arrangements acceptable to the Administrator for the satisfaction of any non-U.S., federal, state, or local income and employment tax withholding obligations, including, without
limitation, obligations incident to the receipt of Shares. Upon exercise or vesting of an Award the Company shall withhold or collect from the Grantee an amount sufficient to satisfy such tax obligations, including, but not limited to, by surrender
of the whole number of Shares covered by the Award sufficient to satisfy the minimum applicable tax withholding obligations incident to the exercise or vesting of an Award (reduced to the lowest whole number of Shares if such number of Shares
withheld would result in withholding a fractional Share with any remaining tax withholding settled in cash). 

  
 13 













 8.     Exercise of Award. 

(a)     Procedure for Exercise; Rights as a Stockholder 

(i)     Any Award granted hereunder shall be exercisable at such times and under such conditions as determined by the
Administrator under the terms of the Plan and specified in the Award Agreement. 
 (ii)     An Award shall be deemed to
be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Award by the person entitled to exercise the Award and full payment for the Shares with respect to which the Award is exercised has
been made, including, to the extent selected, use of the broker-dealer sale and remittance procedure to pay the purchase price as provided in Section 7(b)(v). 

(b)     Exercise of Award Following Termination of Continuous Service. In the event of termination of a
Grantee’s Continuous Service for any reason other than Disability or death (but not in the event of a Grantee’s change of status from Employee to Consultant or from Consultant to Employee), such Grantee may, but only during the
Post-Termination Exercise Period (but in no event later than the expiration date of the term of such Award as set forth in the Award Agreement), exercise the portion of the Grantee’s Award that was vested at the date of such termination or such
other portion of the Grantee’s Award as may be determined by the Administrator. The Grantee’s Award Agreement may provide that upon the termination of the Grantee’s Continuous Service for Cause, the Grantee’s right to exercise
the Award shall terminate concurrently with the termination of Grantee’s Continuous Service. In the event of a Grantee’s change of status from Employee to Consultant, an Employee’s Incentive Stock Option shall convert automatically to
a Non-Qualified Stock Option on the day three (3) months and one day following such change of status. To the extent that the Grantee’s Award was unvested at the date of termination, or if the Grantee
does not exercise the vested portion of the Grantee’s Award within the Post-Termination Exercise Period, the Award shall terminate. 

(c)     Disability of Grantee. In the event of termination of a Grantee’s Continuous Service as a result of
his or her Disability, such Grantee may, but only within twelve (12) months from the date of such termination (or such longer period as specified in the Award Agreement but in no event later than the expiration date of the term of such Award as
set forth in the Award Agreement), exercise the portion of the Grantee’s Award that was vested at the date of such termination; provided, however, that if such Disability is not a “disability” as such term is defined in
Section 22(e)(3) of the Code, in the case of an Incentive Stock Option such Incentive Stock Option shall automatically convert to a Non-Qualified Stock Option on the day three (3) months and one day
following such termination. To the extent that the Grantee’s Award was unvested at the date of termination, or if Grantee does not exercise the vested portion of the Grantee’s Award within the time specified herein, the Award shall
terminate. 
 (d)     Death of Grantee. In the event of a termination of the Grantee’s Continuous Service as
a result of his or her death, or in the event of the death of the Grantee during the Post-Termination Exercise Period or during the twelve (12) month period following the Grantee’s termination of Continuous Service as a result of his or
her Disability, the Grantee’s estate or a person who acquired the right to exercise the Award by bequest or inheritance may exercise the portion of the Grantee’s Award that was vested as of the date of termination, within


  
 14 













 twelve (12) months from the date of death (or such longer period as specified in the Award Agreement
but in no event later than the expiration of the term of such Award as set forth in the Award Agreement). To the extent that, at the time of death, the Grantee’s Award was unvested, or if the Grantee’s estate or a person who acquired the
right to exercise the Award by bequest or inheritance does not exercise the vested portion of the Grantee’s Award within the time specified herein, the Award shall terminate.     

(e)     Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of an Award within
the applicable time periods set forth in this Section 8 is prevented by the provisions of Section 9 below, the Award shall remain exercisable until one (1) month after the date the Grantee is notified by the Company that the Award is
exercisable, but in any event no later than the expiration of the term of such Award as set forth in the Award Agreement and only in a manner and to the extent permitted under Code Section 409A. 

9.     Conditions Upon Issuance of Shares. 

(a)     If at any time the Administrator determines that the delivery of Shares pursuant to the exercise, vesting or any
other provision of an Award is or may be unlawful under Applicable Laws, the vesting or right to exercise an Award or to otherwise receive Shares pursuant to the terms of an Award shall be suspended until the Administrator determines that such
delivery is lawful and shall be further subject to the approval of counsel for the Company with respect to such compliance. The Company shall have no obligation to effect any registration or qualification of the Shares under federal or state laws.

 (b)     As a condition to the exercise of an Award, the Company may 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 if, in the opinion of counsel for the Company, such a representation
is required by any Applicable Laws. 
 10.     Adjustments Upon Changes in Capitalization. Subject to any
required action by the stockholders of the Company and Section 11 below, the number of Shares covered by each outstanding Award, and the number of Shares which have been authorized for issuance under the Plan but as to which no Awards have yet
been granted or which have been returned to the Plan, the exercise or purchase price of each such outstanding Award, the maximum number of Shares with respect to which Awards may be granted to any Grantee in any calendar year, as well as any other
terms that the Administrator determines require adjustment shall be proportionately adjusted for (i) any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Shares, or similar transaction affecting the Shares, (ii) any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company, or (iii) any other transaction with
respect to Common Stock including a corporate merger, consolidation, acquisition of property or stock, separation (including a spin-off or other distribution of stock or property), reorganization, liquidation
(whether partial or complete) or any similar transaction; provided, however that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” In the event of any
distribution of cash or other assets to stockholders other than a normal cash dividend, the Administrator shall also make such adjustments as provided in this Section 10 or substitute, exchange or grant Awards to effect


  
 15 













 
such adjustments (collectively “adjustments”). Any such adjustments to outstanding Awards will be effected in a manner that precludes the enlargement of rights and benefits under such
Awards. In connection with the foregoing adjustments, the Administrator may, in its discretion, prohibit the exercise of Awards or other issuance of Shares, cash or other consideration pursuant to Awards during certain periods of time. Except as the
Administrator determines, no issuance by the Company of shares of any class, or securities convertible into shares of any class, shall affect, and no adjustment by reason hereof shall be made with respect to, the number or price of Shares subject to
an Award. 
 11.     Corporate Transactions. 

(a)     Termination of Award to Extent Not Assumed in Corporate Transaction. Effective upon the consummation of a
Corporate Transaction, all outstanding Awards under the Plan shall terminate. However, all such Awards shall not terminate to the extent they are Assumed in connection with the Corporate Transaction. 

(b)     Acceleration of Award Upon Corporate Transaction. The Administrator shall have the authority, exercisable
either in advance of any actual or anticipated Corporate Transaction or at the time of an actual Corporate Transaction and exercisable at the time of the grant of an Award under the Plan or any time while an Award remains outstanding, to provide for
the full or partial automatic vesting and exercisability of one or more outstanding unvested Awards under the Plan and the release from restrictions on transfer and repurchase or forfeiture rights of such Awards in connection with a Corporate
Transaction, on such terms and conditions as the Administrator may specify. The Administrator also shall have the authority to condition any such Award vesting and exercisability or release from such limitations upon the subsequent termination of
the Continuous Service of the Grantee within a specified period following the effective date of the Corporate Transaction. The Administrator may provide that any Awards so vested or released from such limitations in connection with a Corporate
Transaction, shall remain fully exercisable until the expiration or sooner termination of the Award. 
 (c)    
Effect of Acceleration on Incentive Stock Options. Any Incentive Stock Option accelerated under this Section 11 in connection with a Corporate Transaction shall remain exercisable as an Incentive Stock Option under the Code only to the
extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. 
 12.     Effective Date
and Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company. It shall continue in effect for a term of ten (10) years unless sooner terminated.
Subject to Section 17 below, and Applicable Laws, Awards may be granted under the Plan upon its becoming effective. 

13.     Amendment, Suspension or Termination of the Plan. 

(a)     The Board may at any time amend, suspend or terminate the Plan. To the extent necessary to comply with Applicable
Laws, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required. 

  
 16 













 (b)     No Award may be granted during any suspension of the Plan or
after termination of the Plan. 
 (c)     No suspension or termination of the Plan (including termination of the Plan
under Section 12, above) shall adversely affect any rights under Awards already granted to a Grantee. 
 14.    
Reservation of Shares. 
 (a)     The Company, during the term of the Plan, will at all times reserve and keep
available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
 (b)     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. 

15.     No Effect on Terms of Employment/Consulting Relationship. The Plan shall not confer upon any Grantee any
right with respect to the Grantee’s Continuous Service, nor shall it interfere in any way with his or her right or the right of the Company or any Related Entity to terminate the Grantee’s Continuous Service at any time, with or without
cause, including but not limited to, Cause, and with or without notice. The ability of the Company or any Related Entity to terminate the employment of a Grantee who is employed at will is in no way affected by its determination that the
Grantee’s Continuous Service has been terminated for Cause for the purposes of this Plan. 
 16.     No Effect
on Retirement and Other Benefit Plans. Except as specifically provided in a retirement or other benefit plan of the Company or a Related Entity, Awards shall not be deemed compensation for purposes of computing benefits or contributions under
any retirement plan of the Company or a Related Entity, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of
compensation. The Plan is not a “Pension Plan” or “Welfare Plan” under the Employee Retirement Income Security Act of 1974, as amended. 

17.     Stockholder Approval. Continuance of the Plan shall be subject to approval by the stockholders of the
Company within twelve (12) months before or after the date the Plan is adopted. Such stockholder approval shall be obtained in the degree and manner required under Applicable Laws. Any Award exercised before stockholder approval is obtained
shall be rescinded if stockholder approval is not obtained within the time prescribed, and Shares issued on the exercise of any such Award shall not be counted in determining whether stockholder approval is obtained. 

18.     Information to Grantees. To the extent required by Applicable Laws, the Company shall provide to each
Grantee, during the period for which such Grantee has one or more Awards outstanding, copies of financial statements at least annually. The Company shall not be required to provide such information to persons whose duties in connection with the
Company assure them access to equivalent information. 

  
 17 













 19.     Effect of Section 162(m) of the Code.
Section 162(m) of the Code does not apply to the Plan prior to the Registration Date or such earlier time that the Company first becomes subject to the reporting obligations of Section 12 of the Exchange Act. Following the Registration
Date or such earlier time that the Company first becomes subject to the reporting obligations of Section 12 of the Exchange Act, the Plan, and all Awards (except Awards of Restricted Stock that vest over time) issued thereunder, are intended to
be exempt from the application of Section 162(m) of the Code, which restricts under certain circumstances the Federal income tax deduction for compensation paid by a public company to named executives in excess of $1 million per year. The
exemption is based on Treasury Regulation Section 1.162-27(f), in the form existing on the effective date of the Plan, with the understanding that such regulation generally exempts from the application of
Section 162(m) of the Code compensation paid pursuant to a plan that existed before a company becomes publicly held. Under such Treasury Regulation, this exemption is available to the Plan for the duration of the period that lasts until the
earliest of (i) the expiration of the Plan, (ii) the material modification of the Plan, (iii) the exhaustion of the maximum number of shares of Common Stock available for Awards under the Plan, as set forth in Section 3(a), (iv)
the first meeting of stockholders at which directors are to be elected that occurs after the close of the third calendar year following the calendar year in which the Company first becomes subject to the reporting obligations of Section 12 of
the Exchange Act, or (v) such other date required by Section 162(m) of the Code and the rules and regulations promulgated thereunder. To the extent that the Administrator determines as of the date of grant of an Award that (i) the
Award is intended to qualify as Performance-Based Compensation and (ii) the exemption described above is no longer available with respect to such Award, such Award shall not be effective until any stockholder approval required under
Section 162(m) of the Code has been obtained. 
 20.     Unfunded Obligation. Grantees shall have the status
of general unsecured creditors of the Company. Any amounts payable to Grantees pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act
of 1974, as amended. Neither the Company nor any Related Entity shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain
at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Grantee account shall not
create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Related Entity and a Grantee, or otherwise create any vested or beneficial interest in any Grantee or the Grantee’s creditors in any assets of
the Company or a Related Entity. The Grantees shall have no claim against the Company or any Related Entity for any changes in the value of any assets that may be invested or reinvested by the Company with respect to the Plan. 

21.     Construction. Captions and titles contained herein are for convenience only and shall not affect the
meaning or interpretation of any provision of the Plan. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive,
unless the context clearly requires otherwise. 

  
 18 













 22.     Nonexclusivity of the Plan. Neither the adoption of the
Plan by the Board, the submission of the Plan to the stockholders of the Company for approval, nor any provision of the Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements
as it may deem desirable, including, without limitation, the granting of Awards otherwise than under the Plan, and such arrangements may be either generally applicable or applicable only in specific cases.

SIGHT SCIENCES, INC. 

2011 STOCK INCENTIVE PLAN 

STOCK OPTION AWARD AGREEMENT 

1.    Grant of Option. Sight Sciences, Inc., a Delaware corporation (the “Company”), hereby grants to the
Grantee (the “Grantee”) named in the Notice of Stock Option Award (the “Notice”), an option (the “Option”) to purchase the Total Number of Shares of Common Stock subject to the Option (the “Shares”) set forth
in the Notice, at the Exercise Price per Share set forth in the Notice (the “Exercise Price”) subject to the terms and provisions of the Notice, this Stock Option Award Agreement (the “Option Agreement”) and the Company’s
2011 Stock Incentive Plan, as amended from time to time (the “Plan”), which are incorporated herein by reference. Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Option Agreement.

 If designated in the Notice as an Incentive Stock Option, the Option is intended to qualify as an Incentive Stock Option as defined in
Section 422 of the Code. However, notwithstanding such designation, the Option will qualify as an Incentive Stock Option under the Code only to the extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. The
$100,000 limitation of Section 422(d) of the Code is calculated based on the aggregate Fair Market Value of the Shares subject to options designated as Incentive Stock Options which become exercisable for the first time by the Grantee during
any calendar year (under all plans of the Company or any Parent or Subsidiary of the Company). For purposes of this calculation, Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value
of the shares subject to such options shall be determined as of the grant date of the relevant option. 

2.    Exercise of Option. 

(a)    Right to Exercise. The Option shall be exercisable during its term in accordance with the Vesting Schedule
set out in the Notice and with the applicable provisions of the Plan and this Option Agreement. The Option shall be subject to the provisions of Section 11 of the Plan relating to the exercisability or termination of the Option in the event of
a Corporate Transaction. The Grantee shall be subject to reasonable limitations on the number of requested exercises during any monthly or weekly period as determined by the Administrator. In no event shall the Company issue fractional Shares. 

(b)    Method of Exercise. The Option shall be exercisable by delivery of an exercise notice (a form of which is
attached as Exhibit A) or by such other procedure as specified from time to time by the Administrator which shall state the election to exercise the Option, the whole number of Shares in respect of which the Option is being exercised, and such other
provisions as may be required by the Administrator. The exercise notice shall be delivered in person, by certified mail, or by such other method (including electronic transmission) as determined from time to time by the Administrator to the Company
accompanied by payment of the Exercise Price and all applicable income and employment taxes required to be withheld. The Option shall be deemed to be exercised upon receipt by the Company of such notice accompanied by the Exercise Price and all
applicable withholding taxes, which, to the extent selected, shall be deemed to be satisfied by use of the broker-dealer sale and remittance procedure to pay the Exercise Price provided in Section 4(d) below to the extent such procedure is
available to the Grantee at the time of exercise and such an exercise would not violate any Applicable Law. 

(c)    Taxes. No Shares will be delivered to the Grantee or other person pursuant to the exercise of the Option
until the Grantee or other person has made arrangements acceptable to the Administrator for the satisfaction of applicable income tax and employment tax withholding obligations, 

  
 1 













 
including, without limitation, such other tax obligations of the Grantee incident to the receipt of Shares. Upon exercise of the Option, the Company or the Grantee’s employer may offset or
withhold (from any amount owed by the Company or the Grantee’s employer to the Grantee) or collect from the Grantee or other person an amount sufficient to satisfy such tax withholding obligations. Furthermore, in the event of any determination
that the Company has failed to withhold a sum sufficient to pay all withholding taxes due in connection with the Option, the Grantee agrees to pay the Company the amount of such deficiency in cash within five (5) days after receiving a written
demand from the Company to do so, whether or not the Grantee is an employee of the Company at that time. 

3.    Grantee’s Representations. The Grantee understands that neither the Option nor the Shares exercisable
pursuant to the Option have been registered under the Securities Act of 1933, as amended or any United States securities laws. In the event the Shares purchasable pursuant to the exercise of the Option have not been registered under the Securities
Act of 1933, as amended, at the time the Option is exercised, the Grantee shall, if requested by the Company, concurrently with the exercise of all or any portion of the Option, deliver to the Company his or her Investment Representation Statement
in the form attached hereto as Exhibit B. 
 4.    Method of Payment. Payment of the Exercise Price shall be made
by any of the following, or a combination thereof, at the election of the Grantee; provided, however, that such exercise method does not then violate any Applicable Law and, provided further, that the portion of the Exercise Price equal to the par
value of the Shares must be paid in cash or other legal consideration permitted by the Delaware General Corporation Law: 

(a)    cash; 

(b)    check; 

(c)    if the exercise occurs on or after the Registration Date, surrender of Shares held for the requisite period, if
any, necessary to avoid a charge to the Company’s earnings for financial reporting purposes, or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require which have a Fair Market Value on the
date of surrender or attestation equal to the aggregate Exercise Price of the Shares as to which the Option is being exercised; or 

(d)    if the exercise occurs on or after the Registration Date, payment through a broker-dealer sale and remittance
procedure pursuant to which the Grantee (i) shall provide written instructions to a Company-designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the
aggregate exercise price payable for the purchased Shares and (ii) shall provide written directives to the Company to deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction.

 5.    Restrictions on Exercise. The Option may not be exercised if the issuance of the Shares subject to the
Option upon such exercise would constitute a violation of any Applicable Laws. In addition, the Option may not be exercised until such time as the Plan has been approved by the stockholders of the Company. If the exercise of the Option within the
applicable time periods set forth in Section 6, 7 and 8 of this Option Agreement is prevented by the provisions of this Section 5, the Option shall remain exercisable until one (1) month after the date the Grantee is notified by the
Company that the Option is exercisable, but in any event no later than the Expiration Date set forth in the Notice. 

6.    Termination or Change of Continuous Service. In the event the Grantee’s Continuous Service terminates,
other than for Cause, the Grantee may, but only during the Post-Termination Exercise Period, exercise the portion of the Option that was vested at the date of such termination (the “Termination Date”). The Post-Termination Exercise Period
shall commence on the Termination Date.

 In the event of termination of the Grantee’s Continuous Service for Cause, the Grantee’s right to
exercise the Option shall, except as otherwise determined by the Administrator, terminate concurrently with the termination of the Grantee’s Continuous Service (also the “Termination Date”). In no event, however, shall the Option be
exercised later than the Expiration Date set forth in the Notice. In the event of the Grantee’s change in status from Employee, Director or Consultant to any other status of Employee, Director or Consultant, the Option shall remain in effect
and the Option shall continue to vest in accordance with the Vesting Schedule set forth in the Notice; provided, however, with respect to any Incentive Stock Option that shall remain in effect after a change in status from Employee to Director or
Consultant, such Incentive Stock Option shall cease to be treated as an Incentive Stock Option and shall be treated as a Non-Qualified Stock Option on the day three (3) months and one (1) day
following such change in status. Except as provided in Sections 7 and 8 below, to the extent that the Option was unvested on the Termination Date, or if the Grantee does not exercise the vested portion of the Option within the
Post-Termination Exercise Period, the Option shall terminate. 
 7.    Disability of Grantee. In the event the
Grantee’s Continuous Service terminates as a result of his or her Disability, the Grantee may, but only within twelve (12) months commencing on the Termination Date (but in no event later than the Expiration Date), exercise the portion of
the Option that was vested on the Termination Date; provided, however, that if such Disability is not a “disability” as such term is defined in Section 22(e)(3) of the Code and the Option is an Incentive Stock Option, such Incentive
Stock Option shall cease to be treated as an Incentive Stock Option and shall be treated as a Non-Qualified Stock Option on the day three (3) months and one (1) day following the Termination Date. To
the extent that the Option was unvested on the Termination Date, or if the Grantee does not exercise the vested portion of the Option within the time specified herein, the Option shall terminate. Section 22(e)(3) of the Code provides that an
individual is permanently and totally disabled if he or she is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or
can be expected to last for a continuous period of not less than twelve (12) months. 
 8.    Death of
Grantee. In the event of the termination of the Grantee’s Continuous Service as a result of his or her death, or in the event of the Grantee’s death during the Post-Termination Exercise Period or during the twelve (12) month
period following the Grantee’s termination of Continuous Service as a result of his or her Disability, the person who acquired the right to exercise the Option pursuant to Section 9 may exercise the portion of the Option that was vested at
the date of termination within twelve (12) months commencing on the date of death (but in no event later than the Expiration Date). To the extent that the Option was unvested on the date of death, or if the vested portion of the Option is not
exercised within the time specified herein, the Option shall terminate. 
 9.    Transferability of Option. The
Option, if an Incentive Stock Option, may not be transferred in any manner other than by will or by the laws of descent and distribution and may be exercised during the lifetime of the Grantee only by the Grantee. The Option, if a Non-Qualified Stock Option, may not be transferred in any manner other than by will or by the laws of descent and distribution; provided, however, that a Non-Qualified Stock
Option may be transferred during the lifetime of the Grantee by gift or pursuant to a domestic relations order to members of the Grantee’s Immediate Family to the extent and in the manner determined by the Administrator. Notwithstanding the
foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Incentive Stock Option or Non-Qualified Stock Option in the event of the Grantee’s death on a beneficiary designation
form provided by the Administrator. Following the death of the Grantee, the Option, to the extent provided in Section 8, may be exercised (a) by the person or persons designated under the deceased Grantee’s beneficiary designation or
(b) in the absence of an effectively designated beneficiary, by the Grantee’s legal representative or by any person empowered to do so under the deceased Grantee’s will or under the then applicable laws of descent and distribution.
The terms of the Option shall be binding upon the executors, administrators, heirs, successors and transferees of the Grantee. 

  
 3 













 10.    Term of Option. The Option must be exercised no later than
the Expiration Date set forth in the Notice or such earlier date as otherwise provided herein. After the Expiration Date or such earlier date, the Option shall be of no further force or effect and may not be exercised. 

11.    Company’s Right of First Refusal. The Grantee acknowledges and agrees that the Shares are subject to a
right of first refusal (“Right of First Refusal”) as set forth in the Bylaws of the Company, which Right of First Refusal is incorporated herein by reference irrespective of whether the Bylaws are amended at some future date to remove the
Right of First Refusal therefrom, and that, except in compliance with such Right of First Refusal, neither the Grantee nor a transferee (either being sometimes referred to herein as the “Holder”) shall sell, hypothecate, encumber or
otherwise transfer any Shares or any right or interest therein. 
 12.    Stop-Transfer Notices. In order to
ensure compliance with the restrictions on transfer set forth in this Option Agreement, the Notice or the Plan, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and, if the Company transfers its
own securities, it may make appropriate notations to the same effect in its own records. 
 13.    Refusal to
Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Option Agreement or (ii) to treat as owner of such Shares or
to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 

14.    Tax Consequences. 

(a)    The Grantee may incur tax liability as a result of the Grantee’s purchase or disposition of the Shares. THE
GRANTEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES. 
 (b)    Notwithstanding
the Company’s good faith determination of the Fair Market Value of the Company’s Common Stock for purposes of determining the Exercise Price Per Share of the Option as set forth in the Notice, the taxing authorities may assert that the
Fair Market Value of the Common Stock on the Date of Award was greater than the Exercise Price Per Share. If designated in the Notice as an Incentive Stock Option, the Option may fail to qualify as an Incentive Stock Option if the Exercise Price Per
Share of the Option is less than the Fair Market Value of the Common Stock on the Date of Award. In addition, under Section 409A of the Code, if the Exercise Price Per Share of the Option is less than the Fair Market Value of the Common Stock
on the Date of Award, the Option may be treated as a form of deferred compensation and the Grantee may be subject to an acceleration of income recognition, an additional 20% tax, plus interest and possible penalties. The Company makes no
representation that the Option will comply with Section 409A of the Code and makes no undertaking to prevent Section 409A of the Code from applying to the Option or to mitigate its effects on any deferrals or payments made in respect of
the Option. The Grantee is encouraged to consult a tax adviser regarding the potential impact of Section 409A of the Code. 

15.    Lock-Up Agreement. 

(a)    Agreement. The Grantee, if requested by the Company and the lead underwriter of any public offering of the
Common Stock (the “Lead Underwriter”), hereby irrevocably agrees not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of
any interest in any Common Stock or any securities convertible into or exchangeable or exercisable for or any other rights to purchase or acquire Common Stock (except Common Stock included in such public offering or acquired on the public market
after such offering) during the 180-day period following the effective date of a registration statement of 

  
 4 













 
the Company filed under the Securities Act of 1933, as amended, or such shorter or longer period of time as the Lead Underwriter shall specify. The Grantee further agrees to sign such documents
as may be requested by the Lead Underwriter to effect the foregoing and agrees that the Company may impose stop-transfer instructions with respect to such Common Stock subject to the lock-up period until the
end of such period. The Company and the Grantee acknowledge that each Lead Underwriter of a public offering of the Company’s stock, during the period of such offering and for the lock-up period
thereafter, is an intended beneficiary of this Section 15. 
 (b)    No Amendment Without Consent of
Underwriter. During the period from identification of a Lead Underwriter in connection with any public offering of the Company’s Common Stock until the earlier of (i) the expiration of the
lock-up period specified in Section 15(a) in connection with such offering or (ii) the abandonment of such offering by the Company and the Lead Underwriter, the provisions of this Section 15 may
not be amended or waived except with the consent of the Lead Underwriter. 
 16.    Restrictive Covenants. As a
condition to this Option, the Grantee agrees as follows: 

(a)    Non-Competition. The Grantee will not, during the term of the
Grantee’s employment and for one (1) year thereafter (the “Restricted Period), in any part of the United States of America, and each state therein (the “Restricted Territory”), (i)(A) engage or provide services to, as an
employee, director, officer, contractor, consultant or other service provider (“Provide Services”), any business competitive to the Business that is developing, manufacturing, marketing, or selling any (1) medical device or drug for
the treatment of dry eye disease, or (2) medical device for the treatment of Glaucoma, or (B) engage in any other line of business the Company is engaged in or has taken material preparatory steps to engage in as of the end of
Grantee’s employment (collectively, the “Business”);, or (ii) become a partner, shareholder, member, investor, lender or otherwise have a financial interest in any person or entity which engages or is preparing to engage in the
Business; provided that, the Grantee may: (x) own, as a passive investment, less than 2% of the outstanding shares of capital stock of any entity traded on a national securities exchange or publicly traded in the
over-the-counter market that engages in or is preparing to engage in the Business, and/or (y) the Grantee may Provide Services to a diversified business entity that
is engaged or preparing to engage in the Business, provided that the Grantee’s services are limited to a division, subsidiary, or unit of business entity that is not engaged in or preparing to engage in the Business, and such entity provides
written assurances to the Company that the Grantee will have no role in or access to information (other than publicly-available information) concerning the Business, and will not be permitted to share information concerning the Business. The
Employee agrees and acknowledges that this Section is necessary to protect the Company’s trade secrets, Confidential Information, and goodwill, and that the Company’s business interests cannot be fully protected through less restrictive
means. 
 (b)    Non-Solicitation of Employees. During the term of the
Grantee’s employment and for one (1) year thereafter, the Grantee will not directly or indirectly solicit, or assist any other person or entity in its solicitation of, any employee or consultant of the Company with whom the Grantee worked
during the Grantee’s employment with the Company to terminate his or her relationship with the Company for the Grantee’s own benefit or for the benefit of any other person or entity. This Section 16(b) only prohibits solicitations
that specifically target such employees or consultants. Accordingly, this Section 16(b) would not be violated by job postings that are widely accessible or by hiring any person (including an employee or consultant of the Company) who responded
to such a posting. 
 (c)    Non-Solicitation of Customers. During the
Restricted Period, the Grantee will not directly or indirectly solicit or attempt to solicit business of or from any customer of the Company for purposes of providing products or services in the Business with respect to any customer or prospective
customer: (i) upon whom the Grantee called as an employee of the Company, (ii) as to whom the Grantee, 

  
 5 













 
directly or indirectly, oversaw individuals who called upon that Customer, (iii) known to the Grantee due to the Grantee’s employment by the Company; or (iv) as to whom the Grantee
received trade secret information of the Company. 
 (d)    Exceptions. Section 16(a), (b), and (c)(i-iii) shall not apply to the Grantee if the Grantee regularly works and resides in the State of California during the Grantee’s employment by the Company, nor to any Grantee working and residing in any
jurisdiction in which this Section 16 would be unlawful. Section 16(a) shall not apply to the Grantee if the Grantee’s employment is terminated by the Company without Cause. 

(e)    Enforced to the Greatest Extent Permitted. If any court determines that any portion of this Section 16
cannot be enforced under applicable law because as restriction is too great in scope or time period, it is the parties intention that the restriction be enforced to the greatest scope or time period permitted by applicable law. 

(f)    Enforcement. The Grantee acknowledges that any breach of this Section 16 would cause irreparable injury
to the Company for which monetary damages would not be an adequate remedy and, therefore, will entitle the Company to injunctive relief (including specific performance) without any requirement to post a bond or prove the inadequacy of monetary
damages. The rights and remedies provided to each party in this Agreement are cumulative and in addition to any other rights and remedies available to such party at law or in equity. 

17.    Entire Agreement: Governing Law. The Notice, 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 the Company and the Grantee with respect to the subject matter hereof, and may not be modified adversely to
the Grantee’s interest except by means of a writing signed by the Company and the Grantee. Nothing in the Notice, the Plan and this Option Agreement (except as expressly provided therein) is intended to confer any rights or remedies on any
persons other than the parties. The Notice, the Plan and this Option Agreement are to be construed in accordance with and governed by the internal laws of the State of Delaware without giving effect to any choice of law rule that would cause
the application of the laws of any jurisdiction other than the internal laws of the State of Delaware to the rights and duties of the parties. Should any provision of the Notice, the Plan or this Option Agreement be determined to be illegal or
unenforceable, such provision shall be enforced to the fullest extent allowed by law and the other provisions shall nevertheless remain effective and shall remain enforceable. 

18.    Construction. The captions used in the Notice and this Option Agreement are inserted for convenience and
shall not be deemed a part of the Option for construction or interpretation. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not
intended to be exclusive, unless the context clearly requires otherwise. 
 19.    Administration and
Interpretation. Any question or dispute regarding the administration or interpretation of the Notice, the Plan or this Option Agreement shall be submitted by the Grantee or by the Company to the Administrator. The resolution of such question or
dispute by the Administrator shall be final and binding on all persons. 
 20.    Venue. The Company, the
Grantee, and the Grantee’s assignees pursuant to Section 9 (the “parties”) agree that any suit, action, or proceeding arising out of or relating to the Notice, the Plan or this Option Agreement shall be brought in the Chancery
Court of the State of Delaware or the United States District Court for the District of Delaware, and that the parties shall submit to the jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any
objection the party 

  
 6 













 
may have to the laying of venue for any such suit, action or proceeding brought in such court. If any one or more provisions of this Section 20 shall for any reason be held invalid or
unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable. 

21.    Notices. Any notice required or permitted hereunder shall be given in writing and shall be deemed
effectively given upon personal delivery, upon deposit for delivery by an internationally recognized express mail courier service or upon deposit in the United States mail by certified mail (if the parties are within the United States), with postage
and fees prepaid, addressed to the other party at its address as shown in these instruments, or to such other address as such party may designate in writing from time to time to the other party. 

22.    Confidentiality. To the extent required by Applicable Law, the Company shall provide to the Grantee, during
the period the Option is outstanding, copies of financial statements of the Company at least annually. The Grantee understands and agrees that such financial statements are confidential and shall not be disclosed by the Grantee, to any entity or
person, for any reason, at any time, without the prior written consent of the Company, unless required by law. If disclosure of such financial statements is required by law, whether through subpoena, request for production, deposition, or otherwise,
the Grantee promptly shall provide written notice to Company, including copies of the subpoena, request for production, deposition, or otherwise, within five (5) business days of their receipt by the Grantee and prior to any disclosure so as to
provide Company an opportunity to move to quash or otherwise to oppose the disclosure. Notwithstanding the foregoing, the Grantee may disclose the terms of such financial statements to his or her spouse or domestic partner, and for legitimate
business reasons, to legal, financial, and tax advisors.

 THE GRANTEE ACKNOWLEDGES AND AGREES THAT THE SHARES SUBJECT TO THE OPTION SHALL VEST, IF AT ALL, ONLY DURING THE PERIOD
OF THE GRANTEE’S CONTINUOUS SERVICE (NOT THROUGH THE ACT OF BEING EMPLOYED, BEING GRANTED THE OPTION OR ACQUIRING SHARES HEREUNDER). THE GRANTEE FURTHER ACKNOWLEDGES AND AGREES THAT NOTHING IN THIS NOTICE, THE OPTION AGREEMENT, OR THE PLAN

2011 STOCK INCENTIVE PLAN 

STOCK OPTION AWARD AGREEMENT 

1. Grant of Option. Sight Sciences, Inc., a Delaware corporation (the “Company”), hereby grants to the Grantee (the
“Grantee”) named in the Notice of Stock Option Award (the “Notice”), an option (the “Option”) to purchase the Total Number of Shares of Common Stock subject to the Option (the “Shares”) set forth in the
Notice, at the Exercise Price per Share set forth in the Notice (the “Exercise Price”) subject to the terms and provisions of the Notice, this Stock Option Award Agreement (the “Option Agreement”), the Section 431 Election
and the UK Sub-Plan to the Company’s 2011 Stock Incentive Plan, as amended from time to time (the “Plan”), which are incorporated herein by reference. Unless otherwise defined herein, the terms
defined in the Plan shall have the same defined meanings in this Option Agreement. 
 2. Exercise of Option. 

(a) Right to Exercise. The Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice
and with the applicable provisions of the Plan and this Option Agreement. The Option shall be subject to the provisions of Section 11 of the Plan relating to the exercisability or termination of the Option in the event of a Corporate
Transaction. The Grantee shall be subject to reasonable limitations on the number of requested exercises during any monthly or weekly period as determined by the Administrator. In no event shall the Company issue fractional Shares. 

(b) Method of Exercise. The Option shall be exercisable by: delivery of an exercise notice (a form of which is attached as Exhibit A)
or by such other procedure as specified from time to time by the Administrator which shall state the election to exercise the Option, the whole number of Shares in respect of which the Option is being exercised; delivery of the signed
Section 431 Election; and such other provisions as may be required by the Administrator. The exercise notice shall be delivered in person, by certified mail, or by such other method (including electronic transmission) as determined from time to
time by the Administrator to the Company accompanied by payment of the Exercise Price and all applicable income and employment taxes required to be withheld (including any Award Tax Liability and Secondary NIC Liability). The Option shall be deemed
to be exercised upon receipt by the Company of such notice accompanied by the signed Section 431 Election and the Exercise Price and all applicable income and employment taxes required to be withheld (including any Award Tax Liability and
Secondary NIC Liability), which, to the extent selected, shall be deemed to be satisfied by use of the broker-dealer sale and remittance procedure to pay the Exercise Price provided in Section 4(d) below to the extent such procedure is
available to the Grantee at the time of exercise and such an exercise would not violate any Applicable Law. 
 3. Tax Consequences.

 (a) Secondary NIC Liability. As a condition of the exercise of this Option, the Grantee irrevocably agrees to reimburse the Company or
any other company or person who is or becomes a Secondary Contributor for any Secondary NIC Liability. 
 (b) Withholding. In the event that
the Company determines that it or any subsidiary is required to account to HM Revenue & Customs for the Option Tax Liability and any Secondary NIC Liability or to withhold any other tax as a result of the exercise of this Option, the
Grantee, as a condition to the exercise of the Option, shall make arrangements satisfactory to the Company to enable it or any subsidiary to satisfy all withholding liabilities. The Grantee shall also make arrangements satisfactory to the Company to
enable it to satisfy any withholding requirements that may arise in connection with the vesting or disposition of Shares purchased by exercising this Option. 












 (c) Tax Consultation. The Grantee understands that he or she may suffer adverse tax
consequences as a result of the Grantee’s purchase or disposition of the Shares. the Grantee represents that he or she will consult with any tax advisors the Grantee deems appropriate in connection with the purchase or disposition of the Shares
and that the Grantee is not relying on the Company or any Affiliate for any tax advice. 
 (d) Section 431 Election. As a further condition
of the exercise of this Option, the Grantee shall have signed a Section 431 Election in the form set out in Exhibit C or in such other form as may be determined by HM Revenue & Customs from time to time. 

(e) Grantee’s Tax Indemnity. 
  

	 	i.	 Indemnity. To the extent permitted by law, the Grantee hereby agrees to indemnify and keep indemnified the
Company, and the Company as trustee for and on behalf of any related corporation, for any Option Tax Liability and Secondary NIC Liability. 


  

	 	ii.	 No Obligation to Issue Shares. The Company shall not be obliged to allot and issue any Shares or any interest
in Shares pursuant to the exercise of this Option unless and until the Grantee has paid to the Company such sum as is, in the opinion of the Company, sufficient to indemnify the Company in full against the Option Tax Liability and the Secondary NIC
Liability, or the Grantee has made such other arrangement as in the opinion of the Company will ensure that the full amount of any Option Tax Liability and any Secondary NIC Liability will be recovered from the Grantee within such period as the
Company may then determine. 


  

	 	iii.	 Right of Retention. In the absence of any such other arrangement being made, the Company shall have the right
to retain out of the aggregate number of shares to which the Grantee would have otherwise been entitled upon the exercise of this Option, such number of Shares as, in the opinion of the Company, will enable the Company to sell as agent for the
Grantee (at the best price which can reasonably expect to be obtained at the time of the sale) and to pay over to the Company sufficient monies out of the net proceeds of sale, after deduction of all fees, commissions and expenses incurred in
relation to such sale, to satisfy the Grantee’s liability under such indemnity. 


 (f) Notwithstanding the
Company’s good faith determination of the Fair Market Value of the Company’s Common Stock for purposes of determining the Exercise Price Per Share of the Option as set forth in the Notice, the taxing authorities may assert that the Fair
Market Value of the Common Stock on the Date of Award was greater than the Exercise Price Per Share. If designated in the Notice as an Incentive Stock Option, the Option may fail to qualify as an Incentive Stock Option if the Exercise Price Per
Share of the Option is less than the Fair Market Value of the Common Stock on the Date of Award. In addition, under Section 409A of the Code, if the Exercise Price Per Share of the Option is less than the Fair Market Value of the Common Stock
on the Date of Award, the Option may be treated as a form of deferred compensation and the Grantee may be subject to an acceleration of income recognition, an additional 20% tax, plus interest and possible penalties. The Company makes no
representation that the Option will comply with Section 409A of the Code and makes no undertaking to prevent Section 409A of the Code from applying to the Option or to mitigate its effects on any deferrals or payments made in respect of
the Option. The Grantee is encouraged to consult a tax adviser regarding the potential impact of Section 409A of the Code. 












 4. Grantee’s Representations. The Grantee understands that neither the Option
nor the Shares exercisable pursuant to the Option have been registered under the Securities Act of 1933, as amended or any United States securities laws. In the event the Shares purchasable pursuant to the exercise of the Option have not been
registered under the Securities Act of 1933, as amended, at the time the Option is exercised, the Grantee shall, if requested by the Company, concurrently with the exercise of all or any portion of the Option, deliver to the Company his or her
Investment Representation Statement in the form attached hereto as Exhibit B. 
 5. Method of Payment. Payment of the Exercise Price
shall be made by any of the following, or a combination thereof, at the election of the Grantee; provided, however, that such exercise method does not then violate any Applicable Law and, provided further, that the portion of the Exercise Price
equal to the par value of the Shares must be paid in cash or other legal consideration permitted by the Delaware General Corporation Law: 

(a) cash; 
 (b) cheque; 

(c) if the exercise occurs on or after the Registration Date, payment through a broker-dealer sale and remittance procedure pursuant to which
the Grantee (i) shall provide written instructions to a Company-designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate exercise price
payable for the purchased Shares and (ii) shall provide written directives to the Company to deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction. 

6. Restrictions on Exercise. The Option may not be exercised if the issuance of the Shares subject to the Option upon such exercise
would constitute a violation of any Applicable Laws. If the exercise of the Option within the applicable time periods set forth in Section 6, 7 and 8 of this Option Agreement is prevented by the provisions of this Section 5, the Option
shall remain exercisable until one (1) month after the date the Grantee is notified by the Company that the Option is exercisable, but in any event no later than the Expiration Date set forth in the Notice. 

7. Termination or Change of Continuous Service. In the event the Grantee’s Continuous Service terminates, other than for Cause,
the Grantee may, but only during the Post-Termination Exercise Period, exercise the portion of the Option that was vested at the date of such termination (the “Termination Date”). The Post-Termination Exercise Period shall commence on the
Termination Date. In the event of termination of the Grantee’s Continuous Service for Cause, the Grantee’s right to exercise the Option shall, except as otherwise determined by the Administrator, terminate concurrently with the termination
of the Grantee’s Continuous Service (also the “Termination Date”). In no event, however, shall the Option be exercised later than the Expiration Date set forth in the Notice. Except as provided in Sections 7 and 8 below, to the extent
that the Option was unvested on the Termination Date, or if the Grantee does not exercise the vested portion of the Option within the Post-Termination Exercise Period, the Option shall terminate. 

8. Disability of Grantee. In the event the Grantee’s Continuous Service terminates as a result of his or her Disability, the
Grantee may, but only within twelve (12) months commencing on the Termination Date (but in no event later than the Expiration Date), exercise the portion of the Option that was vested on the Termination Date. 

9. Death of Grantee. In the event of the termination of the Grantee’s Continuous Service as a result of his or her death, or in
the event of the Grantee’s death during the Post-Termination Exercise Period or during the twelve (12) month period following the Grantee’s termination of Continuous Service as a result of his or her Disability, the Grantee’s
Personal Representative may exercise the portion of the Option that was vested at the date of termination within twelve (12) months commencing on the date of death (but in no event later than the Expiration Date). To the extent that the Option
was unvested on the date of death, or if the vested portion of the Option is not exercised within the time specified herein, the Option shall terminate. 












 10. Transferability of Option. The Option may not be transferred in any manner other
than on the Grantee’s death to the Grantee’s Personal Representative. 
 11. Term of Option. The Option must be exercised
no later than the Expiration Date set forth in the Notice or such earlier date as otherwise provided herein. After the Expiration Date or such earlier date, the Option shall be of no further force or effect and may not be exercised. 

12. Company’s Right of First Refusal. The Grantee acknowledges and agrees that the Shares are subject to a right of first refusal
(“Right of First Refusal”) as set forth in the Bylaws of the Company, which Right of First Refusal is incorporated herein by reference irrespective of whether the Bylaws are amended at some future date to remove the Right of First Refusal
therefrom, and that, except in compliance with such Right of First Refusal, neither the Grantee nor a transferee (either being sometimes referred to herein as the “Holder”) shall sell, hypothecate, encumber or otherwise transfer any Shares
or any right or interest therein. 
 13. Stop-Transfer Notices. In order to ensure compliance with the restrictions on transfer set
forth in this Option Agreement, the Notice or the Plan, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and, if the Company transfers its own securities, it may make appropriate notations to
the same effect in its own records. 
 14. Refusal to Transfer. The Company shall not be required (i) to transfer on its books
any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Option Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee
to whom such Shares shall have been so transferred. 
 15. Lock-Up Agreement. 

a. Agreement. The Grantee, if requested by the Company and the lead underwriter of any public offering of the Common Stock (the
“Lead Underwriter”), hereby irrevocably agrees not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of any interest in any
Common Stock or any securities convertible into or exchangeable or exercisable for or any other rights to purchase or acquire Common Stock (except Common Stock included in such public offering or acquired on the public market after such offering)
during the 180-day period following the effective date of a registration statement of the Company filed under the Securities Act of 1933, as amended, or such shorter or longer period of time as the Lead
Underwriter shall specify. The Grantee further agrees to sign such documents as may be requested by the Lead Underwriter to effect the foregoing and agrees that the Company may impose stop- transfer instructions with respect to such Common Stock
subject to the lock-up period until the end of such period. The Company and the Grantee acknowledge that each Lead Underwriter of a public offering of the Company’s stock, during the period of such
offering and for the lock-up period thereafter, is an intended beneficiary of this Section 15. 

b. No Amendment Without Consent of Underwriter. During the period from identification of a Lead Underwriter in connection with any
public offering of the Company’s Common Stock until the earlier of (i) the expiration of the lock-up period specified in Section 15(a) in connection with such offering or (ii) the
abandonment of such offering by the Company and the Lead Underwriter, the provisions of this Section 15 may not be amended or waived except with the consent of the Lead Underwriter. 












 16. Data protection 

a. As a condition of the grant of the Option, the Grantee hereby explicitly and unambiguously acknowledges the necessity of the collection,
use, processing and transfer, in electronic or other form, of personal data as described in this paragraph by and among, as applicable, the Company and its subsidiaries for the exclusive purpose of implementing, administering and managing the
Option. 
 b. The Grantee understands that the Company and its subsidiaries, may hold certain Data for the purpose of managing and
administering the Option. 
 c. The Grantee acknowledges that Data may be transferred to such Data Recipient as may be selected by the
Company in the future (such as a stock plan service provider or broker), provided that the Company ensures that the Data Recipient maintains a level of privacy broadly equivalent to the standard set forth in the Company’s Internal Privacy
Policy (if any) and in any event, no less than that required by any relevant applicable legislation. The Grantee accepts that Data Recipients may be located in the United States or the European Economic Area or elsewhere and the Data
Recipient’s country may have different data privacy laws and protections than the Grantee’s country. 
 d. The Grantee authorizes
the Company and any Data Recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing the Grantee’s participation in the Option, including any
requisite transfer of Data to a designated broker or other third party with whom the Grantee may elect to deposit any Option Shares acquired upon exercise of the Option, as such Data may be required for the administration of the Option and/or the
subsequent holding of Option Shares on the Grantee’s behalf. 
 e. The Grantee understands Data will be held only as long as necessary
to implement, administer and manage the Grantee’s participation in the Option. 
 f. The Grantee understands that the Grantee may, at
any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, without cost to the Grantee, by contacting in writing the
Grantee’s local human resources representative. Further, the Grantee understands that the Grantee is providing the representations herein on a purely voluntary basis. If the Grantee opposes, or later seeks to oppose any processing of the Data,
the Grantee’s employment status or service and career with the Company will not be affected; the only consequence opposing such processing is that the Company would not be able to grant the Grantee Options or other equity awards or administer
or maintain such awards. Therefore, the Grantee understands that opposing the processing of the Data may affect the Grantee’s ability to participate in the Option or in any future equity awards. 

g. For more information on the consequences of opposing the processing of the Data, the Grantee understands that the Grantee may contact the
Grantee’s local human resources representative. 
 h. As a condition of the grant of the Option, the Grantee unambiguously gives his or
her consent to the transfer of Data, as described in this Agreement, and although countries outside of the European Union may lack legal provisions that offer an adequate level of protection, similar to the General Data Protection Regulation ((EU)
2016/679) or any national implementing laws, regulations and secondary legislation, as amended or updated from time to time, in the UK; the Grantee agrees that Data may be transferred to such countries. 

17. No right to compensation or damages 

a. The Grantee has no right to compensation or damages for any loss in respect of the Option where such loss arises (or is claimed to arise),
in whole or in part, from the termination of the Grantee’s employment; or notice to terminate employment given by or to the Grantee. This exclusion of liability shall apply however termination of employment, or the giving of notice, is caused
other than in a case where a competent tribunal or court, from which there can be no appeal (or which the relevant employing company has decided not to appeal), has found that the cessation of the Grantee’s employment amounted to unfair or
constructive dismissal of the Grantee and however compensation or damages may be claimed. 












 b. The Grantee has no right to compensation or damages for any loss in respect of an Option
where such loss arises (or is claimed to arise), in whole or in part, from any company ceasing to be a subsidiary of the Company; or the transfer of any business from a subsidiary of the Company to any person which is not a subsidiary of the
Company. This exclusion of liability shall apply however the change of status of the relevant company, or the transfer of the relevant business, is caused, and however compensation or damages may be claimed. 

18. Entire Agreement: Governing Law. The Notice, the Plan, the Section 431 Election 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 the Company and the Grantee with respect to the subject matter hereof, and may not be modified
adversely to the Grantee’s interest except by means of a writing signed by the Company and the Grantee. Nothing in the Notice, the Plan and this Option Agreement (except as expressly provided therein) is intended to confer any rights or
remedies on any persons other than the parties. The Notice, the Plan, and this Option Agreement are to be construed in accordance with and governed by the internal laws of the State of California without giving effect to any choice of law rule that
would cause the application of the laws of any jurisdiction other than the internal laws of the State of California to the rights and duties of the parties. Should any provision of the Notice, the Plan or this Option Agreement be determined to be
illegal or unenforceable, such provision shall be enforced to the fullest extent allowed by law and the other provisions shall nevertheless remain effective and shall remain enforceable. The Section 431 Election shall be governed by the laws of
England and Wales. 
 19. Construction. The captions used in the Notice and this Option Agreement are inserted for convenience and
shall not be deemed a part of the Option for construction or interpretation. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not
intended to be exclusive, unless the context clearly requires otherwise. 
 20. Administration and Interpretation. Any question or
dispute regarding the administration or interpretation of the Notice, the Plan or this Option Agreement shall be submitted by the Grantee or by the Company to the Administrator. The resolution of such question or dispute by the Administrator shall
be final and binding on all persons. 
 21. Venue. The Company, the Grantee, and the Grantee’s assignees pursuant to
Section 9 (the “parties”) agree that any suit, action, or proceeding arising out of or relating to the Notice, the Plan or this Option Agreement shall be brought in the United States District Court for the Northern District of
California (or should such court lack jurisdiction to hear such action, suit or proceeding, in a California state court in the County of San Francisco) and that the parties shall submit to the jurisdiction of such court. The parties irrevocably
waive, to the fullest extent permitted by law, any objection the party may have to the laying of venue for any such suit, action or proceeding brought in such court. If any one or more provisions of this Section 19 shall for any reason be held
invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable. 

22. Notices. Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal
delivery, upon deposit for delivery by an internationally recognized express mail courier service or upon deposit in the United States mail by certified mail (if the parties are within the United States), with postage and fees prepaid, addressed to
the other party at its address as shown in these instruments, or to such other address as such party may designate in writing from time to time to the other party. 












 23. Confidentiality. To the extent required by Applicable Law, the Company shall
provide to the Grantee, during the period the Option is outstanding, copies of financial statements of the Company at least annually. The Grantee understands and agrees that such financial statements are confidential and shall not be disclosed by
the Grantee, to any entity or person, for any reason, at any time, without the prior written consent of the Company, unless required by law. If disclosure of such financial statements is required by law, whether through subpoena, request for
production, deposition, or otherwise, the Grantee promptly shall provide written notice to Company, including copies of the subpoena, request for production, deposition, or otherwise, within five (5) business days of their receipt by the
Grantee and prior to any disclosure so as to provide Company an opportunity to move to quash or otherwise to oppose the disclosure. Notwithstanding the foregoing, the Grantee may disclose the terms of such financial statements to his or her spouse
or domestic partner, and for legitimate business reasons, to legal, financial, and tax advisors.

 In connection with the purchase of the above-listed Securities, the undersigned Grantee represents to the Company the
following: 
 (a) Grantee 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. Grantee is acquiring these Securities for investment for Grantee’s own account only and not with a view to, or for resale in connection with, any

 (b)
Grantee 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 Grantee’s investment intent as expressed herein. Grantee 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. Grantee further acknowledges and understands that the Company is under no obligation to register the Securities. Grantee understands that the certificate evidencing the Securities will be
imprinted with a legend which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion of counsel satisfactory to the Company. 

(c) Grantee 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 the Grantee, the exercise will 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, except in the case of affiliates, such Securities may be resold subject to the satisfaction of the applicable conditions specified by Rule 144, including: (1) the availability of certain public information about
the Company, the amount of Securities being sold during any three month period not exceeding specified limitations, the resale being made in an unsolicited “broker’s transaction,” in transactions directly with a “market
maker” or “riskless principal transactions” (as said terms are defined under the Securities Exchange Act of 1934) 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 the grant of
the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require: the availability of current public information about the Company; the resale to occur more than a specified
period after the purchase and full payment (within the meaning of Rule 144) for the Securities; and, in the case of the sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3) and (4) of the
paragraph immediately above. 
 (d) Grantee 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 will 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 will 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. Grantee understands that no assurances can be given that any
such other registration exemption will be available in such event.

SECTION 431 ELECTION 












 Joint Election under s431 ITEPA 2003 for full or partial disapplication of Chapter 2 Income Tax (Earnings
and Pensions) Act 2003 
 One Part Election 
  

	1.	 Between 


  

			
	the Employee	  	[insert name of employee]
	whose National Insurance Number is	  	[insert NINO]
	and	  	
	 the Company (who is the Employee’s employer)
	  	[insert name of company]
	of Company Registration Number	  	[insert CRN]

  

	2.	 Purpose of Election 



This joint election is made pursuant to section 431(1) or 431(2) Income Tax (Earnings and Pensions) Act 2003 (ITEPA) and applies where employment-related
securities, which are restricted securities by reason of section 423 ITEPA, are acquired. 
 The effect of an election under section 431(1) is that, for the
relevant Income Tax and NIC purposes, the employment-related securities and their market value will be treated as if they were not restricted securities and that sections 425 to 430 ITEPA do not apply. An election under section 431(2) will ignore
one or more of the restrictions in computing the charge on acquisition. Additional Income Tax will be payable (with PAYE and NIC where the securities are Readily Convertible Assets). 

 

Should the value of the securities fall following the acquisition, it is possible that Income Tax/NIC that would have arisen because of any
future chargeable event (in the absence of an election) would have been less than the Income Tax/NIC due by reason of this election. Should this be the case, there is no Income Tax/NIC relief available under Part 7 of ITEPA 2003; nor is it available
if the securities acquired are subsequently transferred, forfeited or revert to the original owner. 

  

	3.	 Application 



This joint election is made not later than 14 days after the date of acquisition of the securities by the employee and applies to: 

 

			
	 Number of securities
	  	[insert number]
	 Description of securities
	  	 Common Stock

	 Name of issuer of securities
	  	 Sight Sciences, Inc.


 To be acquired by the Employee after [dd/mm/yyyy] under the terms of the UK
Sub-Plan to the Sight Sciences, Inc. 2011 Stock Incentive Plan.

This election disapplies: 
 S.431(1) ITEPA: All restrictions
attaching to the securities. 
  

	5.	 Declaration
