 2015 STOCK INCENTIVE PLAN 

OF 

PRODIGY SOFTWARE, INC. 

1. Purpose 
 The purpose of this 2015
Stock Incentive Plan (the “Plan”) of Prodigy Software, Inc., a Delaware corporation (the “Company”), is to advance the interests of the Company’s stockholders by enhancing the Company’s ability to
attract, retain and motivate persons who are expected to make important contributions to the Company and by providing such persons with equity ownership opportunities and performance-based incentives that are intended to better align the interests
of such persons with those of the Company’s stockholders. Except where the context otherwise requires, the term “Company” shall include any of the Company’s present or future parent or subsidiary corporations as defined in
Sections 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations thereunder (the “Code”) and any other business venture (including, without limitation, joint venture or limited liability company) in
which the Company has a controlling interest, as determined by the Board of Directors of the Company (the “Board”); provided, however, that such other business ventures shall be limited to entities that, where required
by Section 409A of the Code, are eligible issuers of service recipient stock (as defined in Treas. Reg. Section 1.409A-1(b)(5)(iii)(E), or applicable successor regulation). 

2. Eligibility 
 All of the Company’s
employees, officers and directors, as well as consultants and advisors to the Company (as such terms consultants and advisors are defined and interpreted for purposes of Rule 701 under the Securities Act of 1933, as amended (the “Securities
Act”) (or any successor rule)) are eligible to be granted Awards under the Plan. Each person who is granted an Award under the Plan is deemed a “Participant.” “Award” means Options (as defined in
Section 5), SARs (as defined in Section 6), Restricted Stock (as defined in Section 7), Restricted Stock Units (as defined in Section 7) and Other Stock-Based Awards (as defined in Section 8). 

3. Administration and Delegation 
 (a)
Administration by the Board. The Plan will be administered by the Board. The Board shall have authority to grant Awards and to adopt, amend and repeal such administrative rules, guidelines and practices relating to the Plan as it shall deem
advisable. The Board may construe and interpret the terms of the Plan and any Award agreements entered into under the Plan. The Board may correct any defect, supply any omission or reconcile any inconsistency in the Plan or any Award in the manner
and to the extent it shall deem expedient to carry the Plan into effect and it shall be the sole and final judge of such expediency. All decisions by the Board shall be made in the Board’s sole discretion and shall be final and binding on all
persons having or claiming any interest in the Plan or in any Award. 

  
 1 

 (b) Appointment of Committees. To the extent permitted by applicable law, the Board
may delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board (each, a “Committee”). All references in the Plan to the “Board” shall mean the Board or a Committee of
the Board to the extent that the Board’s powers or authority under the Plan have been delegated to such Committee. 
 4. Stock Available for
Awards 
 (a) Number of Shares. Subject to adjustment under Section 9, Awards may be made under the Plan for up to 2,765,954
shares of common stock, $0.0001 par value per share, of the Company (the “Common Stock”), any or all of which Awards may be in the form of Incentive Stock Options (as defined in Section 5(b)). If any Award expires or is
terminated, surrendered or canceled without having been fully exercised, is forfeited in whole or in part (including as the result of shares of Common Stock subject to such Award being repurchased by the Company at the original issuance price
pursuant to a contractual repurchase right), or results in any Common Stock not being issued, the unused Common Stock covered by such Award shall again be available for the grant of Awards under the Plan. Further, shares of Common Stock tendered to
the Company by a Participant to exercise an Award or to satisfy tax withholding obligations arising with respect to an Award shall be added to the number of shares of Common Stock available for the grant of Awards under the Plan. However, in the
case of Incentive Stock Options, the two immediately preceding sentences shall be subject to any limitations under the Code. Shares issued under the Plan may consist in whole or in part of authorized but unissued shares or treasury shares. 

(b) Substitute Awards. In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of
property or stock of an entity, the Board may grant Awards in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof. Substitute Awards may be granted on such terms as the Board deems
appropriate in the circumstances, notwithstanding any limitations on Awards contained in the Plan. Substitute Awards shall not count against the overall share limit set forth in Section 4(a), except as may be required by reason of
Section 422 and related provisions of the Code. 
 5. Stock Options 

(a) General. The Board may grant options to purchase Common Stock (each, an “Option”) and determine the number of
shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option, including conditions relating to applicable federal or state securities laws, as it
considers necessary or advisable. 
 (b) Incentive Stock Options. An Option that the Board intends to be an “incentive stock
option” as defined in Section 422 of the Code (an “Incentive Stock Option”) shall only be granted to employees of Prodigy Software, Inc., any of Prodigy Software, Inc.’s present or future parent or subsidiary
corporations as defined in Sections 424(e) or (f) of the Code, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code, and shall be subject to and shall be construed consistently with the
requirements of Section 422 of the Code. An Option that is not intended to be an Incentive Stock Option shall be designated a “Nonstatutory Stock Option.” The Company shall have no liability to a Participant, or any other
party, if an Option (or any part thereof) that is intended to be an Incentive Stock Option is not an Incentive Stock Option or if the Company converts an Incentive Stock Option to a Nonstatutory Stock Option. 

  
 2 

 (c) Exercise Price. The Board shall establish the exercise price of each Option and
specify the exercise price in the applicable Option agreement. The exercise price shall be not less than 100% of the fair market value per share of Common Stock, as determined by (or in a manner approved by) the Board (“Fair Market
Value”), on the date the Option is granted. “Fair Market Value” of a share of Common Stock for purposes of the Plan will be determined as follows: 

(1) if the Common Stock is not publicly traded, the Board will determine the Fair Market Value for purposes of the Plan using any measure
of value it determines to be appropriate (including, as it considers appropriate, relying on appraisals) in a manner consistent with the valuation principles under Code Section 409A, except as the Board may expressly determine otherwise; 

(2) if the Common Stock trades on a national securities exchange, the closing sale price (for the primary trading session) on the date of
grant; or 
 (3) if the Common Stock does not trade on any such exchange, the average of the closing bid and asked prices as reported by
an authorized OTCBB market data vendor as listed on the OTCBB website (otcbb.com) on the date of grant. 
 For any date that is not a
trading day, the Fair Market Value of a share of Common Stock for such date will be determined by using the closing sale price or average of the bid and asked prices, as appropriate, for the immediately preceding trading day and with the timing in
the formulas above adjusted accordingly. The Board can substitute a particular time of day or other measure of “closing sale price” or “bid and asked prices” if appropriate because of exchange or market procedures or can, in its
sole discretion, use weighted averages either on a daily basis or such longer period as complies with Code Section 409A. 
 The Board
has sole discretion to determine the Fair Market Value for purposes of the Plan, and all Awards are conditioned on the participants’ agreement that the Administrator’s determination is conclusive and binding even though others might make a
different determination. 
 (d) Duration of Options. Each Option shall be exercisable at such times and subject to such terms and
conditions as the Board may specify in the applicable option agreement; provided, however, that no Option will be granted with a term in excess of 10 years. 

(e) Exercise of Options. 

(1) Options may be exercised by delivery to the Company of a notice of exercise in a form of notice (which may be electronic) approved by the
Company, together with payment in full (in a manner specified in Section 5(f)) of the exercise price for the number of shares for which the Option is exercised. Shares of Common Stock subject to the Option will be delivered by the Company as
soon as practicable following exercise. 

  
 3 

 (2) Unless a Participant’s employment is terminated for cause (as defined by applicable
law, the terms of the Plan or option grant or a contract of employment), in the event of termination of employment of such Participant, such Participant shall have the right to exercise an Option, to the extent that such Participant is entitled to
exercise such Option on the date employment terminated, until the earlier of: (i) at least six (6) months from the date of termination, if termination was caused by such Participant’s death or disability, (ii) at least thirty
(30) days from the date of termination, if termination was caused other than by such Participant’s death or disability and (iii) the Option expiration date. 

(f) Payment Upon Exercise. Common Stock purchased upon the exercise of an Option granted under the Plan shall be paid for as follows:

 (1) in cash or by check, payable to the order of the Company; 

(2) when the Common Stock is registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
except as may otherwise be provided in the applicable Option agreement or approved by the Board, in its sole discretion, by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company
sufficient funds to pay the exercise price and any required tax withholding or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company
cash or a check sufficient to pay the exercise price and any required tax withholding; 
 (3) when the Common Stock is registered under
the Exchange Act and to the extent provided for in the applicable Option agreement or approved by the Board, in its sole discretion, by delivery (either by actual delivery or attestation) of shares of Common Stock owned by the Participant valued at
their Fair Market Value, provided (i) such method of payment is then permitted under applicable law, (ii) such Common Stock, if acquired directly from the Company, was owned by the Participant for such minimum period of time, if
any, as may be established by the Board in its discretion and (iii) such Common Stock is not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements; 

(4) to the extent provided for in the applicable Nonstatutory Stock Option agreement or approved by the Board in its sole discretion, by
delivery of a notice of “net exercise” to the Company, as a result of which the Participant would pay the exercise price for the portion of the Option being exercised by cancelling a portion of the Option for such number of shares as is
equal to the exercise price divided by the excess of the Fair Market Value on the date of exercise over the Option exercise price per share. 

(5) to the extent permitted by applicable law and provided for in the applicable Option agreement or approved by the Board, in its sole
discretion, by (i) delivery of a promissory note of the Participant to the Company on terms determined by the Board, or (ii) payment of such other lawful consideration as the Board may determine; or 

(6) by any combination of the above permitted forms of payment. 

  
 4 

 6. Stock Appreciation Rights 

(a) General. The Board may grant Awards consisting of stock appreciation rights (“SARs”) entitling the holder, upon
exercise, to receive an amount of Common Stock or cash or a combination thereof (such form to be determined by the Board) determined by reference to appreciation, from and after the date of grant, in the Fair Market Value of a share of Common Stock
over the measurement price established pursuant to Section 6(b). The date as of which such appreciation is determined shall be the exercise date. 

(b) Measurement Price. The Board shall establish the measurement price of each SAR and specify it in the applicable SAR agreement. The
measurement price shall not be less than 100% of the Fair Market Value on the date the SAR is granted. 
 (c) Duration of SARs. Each
SAR shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable SAR agreement; provided, however, that no SAR will be granted with a term in excess of 10 years. 

(d) Exercise of SARs. SARs may be exercised by delivery to the Company of a notice of exercise in a form (which may be electronic)
approved by the Company, together with any other documents required by the Board. 
 7. Restricted Stock; Restricted Stock Units 

(a) General. The Board may grant Awards entitling recipients to acquire shares of Common Stock (“Restricted Stock”),
subject to the right of the Company to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) from the recipient in the event that conditions
specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for such Award. The Board may also grant Awards entitling the recipient to receive shares of
Common Stock or cash to be delivered at the time such Award vests (“Restricted Stock Units”) (Restricted Stock and Restricted Stock Units are each referred to herein as a “Restricted Stock Award”). 

(b) Terms and Conditions for All Restricted Stock Awards. The Board shall determine the terms and conditions of a Restricted Stock
Award, including the conditions for vesting and repurchase (or forfeiture) and the issue price, if any. 
 (c) Additional Provisions
Relating to Restricted Stock. 
 (1) Dividends. Unless otherwise provided in the applicable Award agreement, any dividends
(whether paid in cash, stock or property) declared and paid by the Company with respect to shares of Restricted Stock (“Accrued Dividends”) shall be paid to the Participant only if and when such shares become free from the
restrictions on transferability and forfeitability that apply to such shares. Each payment of Accrued Dividends will be made no later than the end of the calendar year in which the dividends are paid to stockholders of that class of stock or, if
later, the 15th day of the third month following the lapsing of the restrictions on transferability and the forfeitability provisions applicable to the underlying shares of Restricted Stock. 

  
 5 

 (2) Stock Certificates. The Company may require that any stock certificates issued in
respect of shares of Restricted Stock, as well as dividends or distributions paid on such Restricted Stock, shall be deposited in escrow by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). At the
expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to such restrictions to the Participant or if the Participant has died, to Participant’s Designated Beneficiary.
“Designated Beneficiary” means (i) the beneficiary designated, in a manner determined by the Board, by a Participant to receive amounts due or exercise rights of the Participant in the event of the Participant’s death or
(ii) in the absence of an effective designation by a Participant, “Designated Beneficiary” the Participant’s estate. 

(d) Additional Provisions Relating to Restricted Stock Units. 

(1) Settlement. Upon the vesting of and/or lapsing of any other restrictions (i.e., settlement) with respect to each Restricted Stock
Unit, the Participant shall be entitled to receive from the Company one share of Common Stock or (if so provided in the applicable Award agreement) an amount of cash equal to the Fair Market Value of one share of Common Stock. The Board may, in its
discretion, provide that settlement of Restricted Stock Units shall be deferred, on a mandatory basis or at the election of the Participant in a manner that complies with Section 409A of the Code. 

(2) Voting Rights. A Participant shall have no voting rights with respect to any Restricted Stock Units. 

(3) Dividend Equivalents. The Award agreement for Restricted Stock Units may provide Participants with the right to receive an amount
equal to any dividends or other distributions declared and paid on an equal number of outstanding shares of Common Stock (“Dividend Equivalents”). Dividend Equivalents may be paid currently or credited to an account for the
Participants, may be settled in cash and/or shares of Common Stock and may be subject to the same restrictions on transfer and forfeitability as the Restricted Stock Units with respect to which paid, in each case to the extent provided in the
applicable Award agreement. 
 8. Other Stock-Based Awards 

(a) General. Other Awards of shares of Common Stock, and other Awards that are valued in whole or in part by reference to, or are
otherwise based on, shares of Common Stock or other property, may be granted hereunder to Participants (“Other Stock-Based-Awards”). Such Other Stock-Based Awards shall also be available as a form of payment in the settlement of
other Awards granted under the Plan or as payment in lieu of compensation to which a Participant is otherwise entitled. Other Stock-Based Awards may be paid in shares of Common Stock or cash, as the Board shall determine. 

(b) Terms and Conditions. Subject to the provisions of the Plan, the Board shall determine the terms and conditions of each Other
Stock-Based Award, including any purchase price applicable thereto. 

  
 6 

 (c) Additional Limitations for Other Stock-Based Awards. The terms of all Awards
granted to a Participant under this Section 8 shall comply, to the extent applicable, with Sections 260.140.42, 260.140.45 and 260.140.46 of the California Code of Regulations. 

9. Adjustments for Changes in Common Stock and Certain Other Events 

(a) Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of
shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of Common Stock other than an ordinary cash dividend, (i) the
number and class of securities available under the Plan, (ii) the number and class of securities and exercise price per share of each outstanding Option, (iii) the share and per-share provisions and
the measurement price of each outstanding SAR, (iv) the number of shares subject to and the repurchase price per share subject to each outstanding Restricted Stock Award and (v) the share and
per-share-related provisions and the purchase price, if any, of each outstanding Other Stock-Based Award, shall be equitably adjusted by the Company (or substituted Awards may be made, if applicable) in the
manner determined by the Board. Without limiting the generality of the foregoing, in the event the Company effects a split of the Common Stock by means of a stock dividend and the exercise price of and the number of shares subject to an outstanding
Option are adjusted as of the date of the distribution of the dividend (rather than as of the record date for such dividend), then an optionee who exercises an Option between the record date and the distribution date for such stock dividend shall be
entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon such Option exercise, notwithstanding the fact that such shares were not outstanding as of the close of business on the record
date for such stock dividend. 
 (b) Reorganization Events. 

(1) Definition. A “Reorganization Event” shall mean: (a) any merger or consolidation of the Company with or into
another entity as a result of which all of the Common Stock of the Company is converted into or exchanged for the right to receive cash, securities or other property or is cancelled, (b) any transfer or disposition of all of the Common Stock of
the Company for cash, securities or other property pursuant to a share exchange or other transaction or (c) any liquidation or dissolution of the Company. 

(2) Consequences of a Reorganization Event on Awards Other than Restricted Stock. 

(i) In connection with a Reorganization Event, the Board may take any one or more of the following actions as to all or any (or any portion
of) outstanding Awards other than Restricted Stock on such terms as the Board determines (except to the extent specifically provided otherwise in an applicable Award agreement or another agreement between the Company and the Participant): (i)
provide that such Awards shall be assumed, or substantially equivalent Awards shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to a Participant, provide that all of the
Participant’s unexercised Awards will terminate immediately prior to the consummation of such Reorganization Event unless exercised by the Participant (to the extent then exercisable) within a 

  
 7 

 
specified period following the date of such notice, (iii) provide that outstanding Awards shall become exercisable, realizable, or deliverable, or restrictions applicable to an Award shall
lapse, in whole or in part prior to or upon such Reorganization Event, (iv) in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share surrendered
in the Reorganization Event (the “Acquisition Price”), make or provide for a cash payment to Participants with respect to each Award held by a Participant equal to (A) the number of shares of Common Stock subject to the vested
portion of the Award (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such Reorganization Event) multiplied by (B) the excess, if any, of (I) the Acquisition Price over (II) the exercise,
measurement or purchase price of such Award and any applicable tax withholdings, in exchange for the termination of such Award, (v) provide that, in connection with a liquidation or dissolution of the Company, Awards shall convert into the
right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings) and (vi) any combination of the foregoing. In taking any of the actions permitted under this
Section 9(b)(2), the Board shall not be obligated by the Plan to treat all Awards, all Awards held by a Participant, or all Awards of the same type, identically. 

(ii) Notwithstanding the terms of Section 9(b)(2)(i), in the case of outstanding Restricted Stock Units that are subject to
Section 409A of the Code: (i) if the applicable Restricted Stock Unit agreement provides that the Restricted Stock Units shall be settled upon a “change in control event” within the meaning of Treasury Regulation Section 1.409A-3(i)(5)(i), and the Reorganization Event constitutes such a “change in control event”, then no assumption or substitution shall be permitted pursuant to Section 9(b)(2)(i)(i) and
the Restricted Stock Units shall instead be settled in accordance with the terms of the applicable Restricted Stock Unit agreement; and (ii) the Board may only undertake the actions set forth in clauses (iii), (iv) or (v) of
Section 9(b)(2)(i) if the Reorganization Event constitutes a “change in control event” as defined under Treasury Regulation Section 1.409A-3(i)(5)(i) and such action is permitted or
required by Section 409A of the Code; if the Reorganization Event is not a “change in control event” as so defined or such action is not permitted or required by Section 409A of the Code, and the acquiring or succeeding
corporation does not assume or substitute the Restricted Stock Units pursuant to clause (i) of Section 9(b)(2)(i), then the unvested Restricted Stock Units shall terminate immediately prior to the consummation of the Reorganization Event
without any payment in exchange therefor. 
 (iii) For purposes of Section 9(b)(2)(i)(i), an Award (other than Restricted Stock) shall
be considered assumed if, following consummation of the Reorganization Event, such Award confers the right to purchase or receive pursuant to the terms of such Award, for each share of Common Stock subject to the Award immediately prior to the
consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the
consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the
consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for
the consideration to be received upon the 

  
 8 

 
exercise or settlement of the Award to consist solely of such number of shares of common stock of the acquiring or succeeding corporation (or an affiliate thereof) that the Board determined to be
equivalent in value (as of the date of such determination or another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event. 

(3) Consequences of a Reorganization Event on Restricted Stock. Upon the occurrence of a Reorganization Event other than a liquidation
or dissolution of the Company, the repurchase and other rights of the Company with respect to outstanding Restricted Stock shall inure to the benefit of the Company’s successor and shall, unless the Board determines otherwise, apply to the
cash, securities or other property which the Common Stock was converted into or exchanged for pursuant to such Reorganization Event in the same manner and to the same extent as they applied to such Restricted Stock; provided, however,
that the Board may provide for termination or deemed satisfaction of such repurchase or other rights under the instrument evidencing any Restricted Stock or any other agreement between a Participant and the Company, either initially or by amendment.
Upon the occurrence of a Reorganization Event involving the liquidation or dissolution of the Company, except to the extent specifically provided to the contrary in the instrument evidencing any Restricted Stock or any other agreement between a
Participant and the Company, all restrictions and conditions on all Restricted Stock then outstanding shall automatically be deemed terminated or satisfied. 

(c) Additional Restriction Regarding Recapitalizations, Stock Splits, Etc. For purposes of this Section 9, in the event of a stock
split, reverse stock split, stock dividend, recapitalization, combination, reclassification or other distribution of the Company’s securities underlying the Award without the receipt of consideration by the Company, the number of securities
purchasable, and in the case of Options, the exercise price of such Options, must be proportionately adjusted. 
 10. General Provisions Applicable to
Awards. 
 (a) Transferability of Awards. Awards (or any interest in an Award, including, prior to exercise, any interest in
shares of Common Stock issuable upon exercise of an Option or SAR) shall not be sold, assigned, transferred (including by establishing any short position, put equivalent position (as defined in Rule 16a-1
issued under the Exchange Act) or call equivalent position (as defined in Rule 16a-1 issued under the Exchange Act)), pledged, hypothecated or otherwise encumbered by the person to whom they are granted,
either voluntarily or by operation of law, and, during the life of the Participant, shall be exercisable only by the Participant; except that Awards, other than Awards subject to Section 409A of the Code, may be transferred to family members
(as defined in Rule 701(c)(3) under the Securities Act) through gifts or (other than Incentive Stock Options) domestic relations orders or to an executor or guardian upon the death of the Participant. The Company shall not be required to recognize
any such permitted transfer until such time as such permitted transferee shall deliver to the Company a written instrument, as a condition to such transfer, in form and substance satisfactory to the Company confirming that such transferee shall be
bound by all of the terms and conditions of the Award. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees. For the avoidance of doubt, nothing contained in this Section 10(a)
shall be deemed to restrict a transfer to the Company. 

  
 9 

 (b) Documentation. Each Award shall be evidenced in such form (written, electronic or
otherwise) as the Board shall determine. Each Award may contain terms and conditions in addition to those set forth in the Plan. 
 (c)
Board Discretion. Except as otherwise provided by the Plan, each Award may be made alone or in addition or in relation to any other Award. The terms of each Award need not be identical, and the Board need not treat Participants uniformly.

 (d) Termination of Status. The Board shall determine the effect on an Award of the disability, death, termination or other
cessation of employment, authorized leave of absence or other change in the employment or other status of a Participant and the extent to which, and the period during which, the Participant, or the Participant’s legal representative,
conservator, guardian or Designated Beneficiary, may exercise rights under the Award. 
 (e) Withholding. The Participant must satisfy
all applicable federal, state, and local or other income and employment tax withholding obligations before the Company will deliver stock certificates or otherwise recognize ownership of Common Stock under an Award. The Company may decide to satisfy
the withholding obligations through additional withholding on salary or wages. If the Company elects not to or cannot withhold from other compensation, the Participant must pay the Company the full amount, if any, required for withholding or have a
broker tender to the Company cash equal to the withholding obligations. Payment of withholding obligations is due before the Company will issue any shares on exercise, vesting or release from forfeiture of an Award or at the same time as payment of
the exercise or purchase price unless the Company determines otherwise. If provided for in an Award or approved by the Board in its sole discretion, a Participant may satisfy such tax obligations in whole or in part by delivery (either by actual
delivery or attestation) of shares of Common Stock, including shares retained from the Award creating the tax obligation, valued at their Fair Market Value; provided, however, except as otherwise provided by the Board, that the total tax
withholding where stock is being used to satisfy such tax obligations cannot exceed the Company’s minimum statutory withholding obligations (based on minimum statutory withholding rates for federal and state tax purposes, including payroll
taxes, that are applicable to such supplemental taxable income). Shares used to satisfy tax withholding requirements cannot be subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements. 

(f) Amendment of Award. 

(1) The Board may amend, modify or terminate any outstanding Award, including but not limited to, substituting therefor another Award of the
same or a different type, changing the date of exercise or realization, and converting an Incentive Stock Option to a Nonstatutory Stock Option. The Participant’s consent to such action shall be required unless (i) the Board determines
that the action, taking into account any related action, does not materially and adversely affect the Participant’s rights under the Plan or (ii) the change is permitted under Section 9. 

  
 10 

 (2) The Board may, without stockholder approval, amend any outstanding Award granted under
the Plan to provide an exercise price per share that is lower than the then-current exercise price per share of such outstanding Award. The Board may also, without stockholder approval, cancel any outstanding award (whether or not granted under the
Plan) and grant in substitution therefor new Awards under the Plan covering the same or a different number of shares of Common Stock and having an exercise price per share lower than the then-current exercise price per share of the cancelled award.

 (g) Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan
or to remove restrictions from shares previously issued or delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all
other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and regulations and any applicable stock exchange or stock market rules and regulations, and (iii) the
Participant has executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules or regulations. 

(h) Acceleration. The Board may at any time provide that any Award shall become immediately exercisable in whole or in part, free of
some or all restrictions or conditions, or otherwise realizable in whole or in part, as the case may be. 
 (i) Additional Limitations on
Timing of Awards. No Award granted to a Participant shall become exercisable, vested or realizable, as applicable to such Award, unless the Plan has been approved by the holders of a majority of the Company’s outstanding voting securities
by the later of (i) within twelve (12) months before or after the date the Plan was adopted by the Board, or (ii) prior to or within twelve (12) months of the granting of any Award to a Participant. 

11. Miscellaneous. 
 (a) No Right To
Employment or Other Status. No person shall have any claim or right to be granted an Award by virtue of the adoption of the Plan, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any
other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan, except as expressly provided in the
applicable Award. 
 (b) No Rights As Stockholder. Subject to the provisions of the applicable Award, no Participant or Designated
Beneficiary shall have any rights as a stockholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder of such shares. 

(c) Effective Date and Term of Plan. The Plan shall become effective on the date on which it is adopted by the Board. No Awards shall be
granted under the Plan after the expiration of 10 years from the earlier of (i) the date on which the Plan was adopted by the Board or (ii) the date the Plan was approved by the Company’s stockholders, but Awards previously granted
may extend beyond that date. 

  
 11 

 (d) Amendment of Plan. The Board may amend, suspend or terminate the Plan or any
portion thereof at any time; provided that if at any time the approval of the Company’s stockholders is required as to any modification or amendment under Section 422 of the Code or any successor provision with respect to Incentive
Stock Options, the Board may not effect such modification or amendment without such approval. Unless otherwise specified in the amendment, any amendment to the Plan adopted in accordance with this Section 11(d) shall apply to, and be binding on
the holders of, all Awards outstanding under the Plan at the time the amendment is adopted, provided the Board determines that such amendment, taking into account any related action, does not materially and adversely affect the rights of
Participants under the Plan. 
 (e) Authorization of Sub-Plans (including Grants to non-U.S. Employees). The Board may from time to time establish one or more sub-plans under the Plan for purposes of satisfying applicable securities, tax or other laws of
various jurisdictions. The Board shall establish such sub-plans by adopting supplements to the Plan containing (i) such limitations on the Board’s discretion under the Plan as the Board deems
necessary or desirable or (ii) such additional terms and conditions not otherwise inconsistent with the Plan as the Board shall deem necessary or desirable. All supplements adopted by the Board shall be deemed to be part of the Plan, but each
supplement shall apply only to Participants within the affected jurisdiction and the Company shall not be required to provide copies of any supplement to Participants in any jurisdiction which is not the subject of such supplement. 

(f) Compliance with Section 409A of the Code. Except as provided in individual Award agreements initially or by amendment, if and
to the extent (i) any portion of any payment, compensation or other benefit provided to a Participant pursuant to the Plan in connection with Participant’s employment termination constitutes “nonqualified deferred compensation”
within the meaning of Section 409A of the Code and (ii) the Participant is a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, in each case as determined by the Company in accordance with its procedures, by which
determinations the Participant (through accepting the Award) agrees that the Participant is bound, such portion of the payment, compensation or other benefit shall not be paid before the day that is six months plus one day after the date of
“separation from service” (as determined under Section 409A of the Code) (the “New Payment Date”), except as Section 409A of the Code may then permit. The aggregate of any payments that otherwise would have been
paid to the Participant during the period between the date of separation from service and the New Payment Date shall be paid to the Participant in a lump sum on such New Payment Date, and any remaining payments will be paid on their original
schedule. 
 The Company makes no representations or warranty and shall have no liability to the Participant or any other person if any provisions of or
payments, compensation or other benefits under the Plan are determined to constitute nonqualified deferred compensation subject to Section 409A of the Code but do not to satisfy the conditions of that section. 

(g) Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a director,
officer, other employee, or agent of the Company will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan, nor will such
individual be personally liable with respect to the Plan because of any contract or other instrument such individual executes in such individual’s capacity as a director, officer, other employee, or agent of the Company. The Company will
indemnify and hold harmless each director, officer, other employee, or agent of the Company to whom any duty or power relating to the administration or interpretation of the Plan has been or will be delegated, against any cost or expense (including
attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Board’s approval) arising out of any act or omission to act concerning the Plan unless arising out of such person’s own fraud or bad faith. 

  
 12 

 (h) Governing Law. The provisions of the Plan and all Awards made hereunder shall be
governed by and interpreted in accordance with the laws of the State of Delaware, excluding choice-of-law principles of the law of such state that would require the
application of the laws of a jurisdiction other than the State of Delaware.

 PRODIGY SOFTWARE, INC. 

INCENTIVE STOCK OPTION AGREEMENT 

GRANTED UNDER 2015 STOCK INCENTIVE PLAN 

1. Grant of Option. 
 This Incentive Stock
Option Agreement (the “Agreement”) evidences the grant by Prodigy Software, Inc., a Delaware corporation (the “Company”), on [________ __, 20__] (the “Grant Date”) to [___________], an employee of
the Company (the “Participant”), of an option to purchase, in whole or in part, on the terms provided herein and in the Company’s 20[__] Stock Incentive Plan (the “Plan”), a total of [_________] shares (the
“Shares”) of common stock, $0.0001 par value per share, of the Company (“Common Stock”) at $[_______] per Share. Unless earlier terminated, this option shall expire at 5:00 p.m., Eastern time, on [_______ __,
20__] [date is ten years minus one day from grant date] (the “Final Exercise Date”). 
 It is intended that the
option evidenced by this Agreement shall be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”). Except as otherwise
indicated by the context, the term “Participant”, as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms. 

2. Vesting Schedule. 
 This option will
become exercisable (“vest”) as to 25% of the original number of Shares on the first anniversary of the Vesting Commencement Date (as defined below) and as to an additional 2.0833% of the original number of Shares at the end of each
successive month following the first anniversary of the Vesting Commencement Date until the fourth anniversary of the Vesting Commencement Date. On the fourth anniversary of the Vesting Commencement Date, this option will be exercisable as to
all Shares. For purposes of this Agreement, “Vesting Commencement Date” shall mean [__________________]. 
 The right of
exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the
earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan. 
 3. Exercise of Option. 

(a) Form of Exercise. Each election to exercise this option shall be accompanied by a completed Notice of Stock Option Exercise in the
form attached hereto as Exhibit A, signed by the Participant, and received by the Company at its principal office, accompanied by this Agreement, and payment in full in the manner provided in the Plan. The Participant may purchase less than
the number of Shares covered hereby, provided that no partial exercise of this option may be for any fractional share or for fewer than ten whole shares. 

 (b) Continuous Relationship with the Company Required. Except as otherwise provided
in this Section 3, this option may not be exercised unless the Participant, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee or officer of, or consultant or advisor to, the Company or
any parent or subsidiary of the Company as defined in Section 424(e) or (f) of the Code (an “Eligible Participant”). 

(c) Termination of Relationship with the Company. If the Participant ceases to be an Eligible Participant for any reason, then, except
as provided in paragraphs (d) and (e) below, the right to exercise this option shall terminate three months after such cessation (but in no event after the Final Exercise Date), provided that this option shall be
exercisable only to the extent that the Participant was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, violates the
non-competition or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company, the right to exercise this
option shall terminate immediately upon such violation. 
 (d) Exercise Period Upon Death or Disability. If the Participant dies or
becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for “cause” as specified in
paragraph (e) below, this option shall be exercisable, within the period of one year following the date of death or disability of the Participant, by the Participant (or in the case of death by an authorized transferee), provided
that this option shall be exercisable only to the extent that this option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final
Exercise Date. 
 (e) Termination for Cause. If, prior to the Final Exercise Date, the Participant’s employment is terminated by
the Company for Cause (as defined below), the right to exercise this option shall terminate immediately upon the effective date of such termination of employment. If, prior to the Final Exercise Date, the Participant is given notice by the Company
of the termination of his or her employment by the Company for Cause, and the effective date of such employment termination is subsequent to the date of delivery of such notice, the right to exercise this option shall be suspended from the time of
the delivery of such notice until the earlier of (i) such time as it is determined or otherwise agreed that the Participant’s employment shall not be terminated for Cause as provided in such notice or (ii) the effective date of such
termination of employment (in which case the right to exercise this option shall, pursuant to the preceding sentence, terminate upon the effective date of such termination of employment). If the Participant is party to an employment or severance
agreement with the Company that contains a definition of “cause” for termination of employment, “Cause” shall have the meaning ascribed to such term in such agreement. Otherwise, “Cause” shall mean willful misconduct by
the Participant or willful failure by the Participant to perform his or her responsibilities to the Company (including, without limitation, breach by the Participant of any provision of any employment, consulting, advisory, nondisclosure, non-competition or other similar agreement between the Participant and the Company), as determined by the Company, which determination shall be conclusive. The Participant’s employment shall be considered to
have been terminated for Cause if the Company determines, within 30 days after the Participant’s resignation, that termination for Cause was warranted. 

  
 - 2 - 

 4. Company Right of First Refusal. 

(a) Notice of Proposed Transfer. If the Participant proposes to sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by
operation of law or otherwise (collectively, “transfer”) any Shares acquired upon exercise of this option, then the Participant shall first give written notice of the proposed transfer (the “Transfer Notice”) to the
Company. The Transfer Notice shall name the proposed transferee and state the number of such Shares the Participant proposes to transfer (the “Offered Shares”), the price per share and all other material terms and conditions of the
transfer. 
 (b) Company Right to Purchase. For 30 days following its receipt of such Transfer Notice, the Company shall have the
option to purchase all or part of the Offered Shares at the price and upon the terms set forth in the Transfer Notice. In the event the Company elects to purchase all or part of the Offered Shares, it shall give written notice of such election to
the Participant within such 30-day period. Within 10 days after his or her receipt of such notice, the Participant shall tender to the Company at its principal offices the certificate or certificates
representing the Offered Shares to be purchased by the Company, duly endorsed in blank by the Participant or with duly endorsed stock powers attached thereto, all in a form suitable for transfer of the Offered Shares to the Company. Promptly
following receipt of such certificate or certificates, the Company shall deliver or mail to the Participant a check in payment of the purchase price for such Offered Shares; provided that if the terms of payment set forth in the
Transfer Notice were other than cash against delivery, the Company may pay for the Offered Shares on the same terms and conditions as were set forth in the Transfer Notice; and provided further that any delay in making such payment
shall not invalidate the Company’s exercise of its option to purchase the Offered Shares. 
 (c) Shares Not Purchased By Company.
If the Company does not elect to acquire all of the Offered Shares, the Participant may, within the 30-day period following the expiration of the option granted to the Company under subsection (b) above,
transfer the Offered Shares which the Company has not elected to acquire to the proposed transferee, provided that such transfer shall not be on terms and conditions more favorable to the transferee than those contained in the Transfer
Notice. Notwithstanding any of the above, all Offered Shares transferred pursuant to this Section 4 shall remain subject to the right of first refusal set forth in this Section 4 and such transferee shall, as a condition to such transfer,
deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Section 4. 

(d) Consequences of Non-Delivery. After the time at which the Offered Shares are required to be
delivered to the Company for transfer to the Company pursuant to subsection (b) above, the Company shall not pay any dividend to the Participant on account of such Offered Shares or permit the Participant to exercise any of the privileges or
rights of a stockholder with respect to such Offered Shares, but shall, insofar as permitted by law, treat the Company as the owner of such Offered Shares. 

(e) Exempt Transactions. The following transactions shall be exempt from the provisions of this Section 4: 

(1) any transfer of Shares to or for the benefit of any spouse, child or grandchild of the Participant, or to a trust for their benefit; 

  
 - 3 - 

 (2) any transfer pursuant to an effective registration statement filed by the Company under
the Securities Act of 1933, as amended (the “Securities Act”); and 
 (3) the sale of all or substantially all of the
outstanding shares of capital stock of the Company (including pursuant to a merger or consolidation); 
 provided, however, that in the case
of a transfer pursuant to clause (1) above, such Shares shall remain subject to the right of first refusal set forth in this Section 4. 

(f) Assignment of Company Right. The Company may assign its rights to purchase Offered Shares in any particular transaction under this
Section 4 to one or more persons or entities. 
 (g) Termination. The provisions of this Section 4 shall terminate upon the
earlier of the following events: 
 (1) the closing of the sale of shares of Common Stock in an underwritten public offering pursuant to an
effective registration statement filed by the Company under the Securities Act; or 
 (2) the sale of all or substantially all of the
outstanding shares of capital stock, assets or business of the Company, by merger, consolidation, sale of assets or otherwise (other than a merger or consolidation in which all or substantially all of the individuals and entities who were beneficial
owners of the Company’s voting securities immediately prior to such transaction beneficially own, directly or indirectly, more than 75% (determined on an as-converted basis) of the outstanding securities
entitled to vote generally in the election of directors of the resulting, surviving or acquiring corporation in such transaction). 
 (h)
No Obligation to Recognize Invalid Transfer. The Company shall not be required (1) to transfer on its books any of the Shares which shall have been sold or transferred in violation of any of the provisions set forth in this
Section 4, or (2) to treat as owner of such Shares or to pay dividends to any transferee to whom any such Shares shall have been so sold or transferred. 

(i) Legends. The certificate representing Shares shall bear a legend substantially in the following form (in addition to, or in
combination with, any legend required by applicable federal and state securities laws and agreements relating to the transfer of the Company securities): 

“The shares represented by this certificate are subject to a right of first refusal in favor of the Company, as provided
in a certain stock option agreement with the Company.” 

  
 - 4 - 

 5. Agreement in Connection with Initial Public Offering. 

The Participant agrees, in connection with the initial underwritten public offering of the Common Stock pursuant to a registration statement under the
Securities Act, (i) not to (a) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any other securities of the Company or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of
ownership of shares of Common Stock or other securities of the Company, whether any transaction described in clause (a) or (b) is to be settled by delivery of securities, in cash or otherwise, during the period beginning on the date of the
filing of such registration statement with the Securities and Exchange Commission and ending 180 days after the date of the final prospectus relating to the offering (plus up to an additional 34 days to the extent requested by the managing
underwriters for such offering in order to address NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4) or any similar successor provision), and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the
managing underwriters at the time of such offering. The Company may impose stop-transfer instructions with respect to the shares of Common Stock or other securities subject to the foregoing restriction until the end of the “lock-up” period. 
 6. Tax Matters. 

(a) Withholding. No Shares will be issued pursuant to the exercise of this option unless and until the Participant pays to the Company,
or makes provision satisfactory to the Company for payment of, any federal, state or local withholding taxes required by law to be withheld in respect of this option. 

(b) Disqualifying Disposition. If the Participant disposes of Shares acquired upon exercise of this option within two years from the
Grant Date or one year after such Shares were acquired pursuant to exercise of this option, the Participant shall notify the Company in writing of such disposition. 

7. Transfer Restrictions. 
 (a) This option
may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this option
shall be exercisable only by the Participant. 
 (b) The Participant agrees that he or she will not transfer any Shares issued pursuant to
the exercise of this option unless the transferee, as a condition to such transfer, delivers to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of Section 4 and Section 5;
provided that such a written confirmation shall not be required with respect to (1) Section 4 after such provision has terminated in accordance with Section 4(g) or (2) Section 5 after the completion of the lock-up period in connection with the Company’s initial underwritten public offering. 

  
 - 5 - 

 8. Provisions of the Plan. 

This option is subject to the provisions of the Plan (including the provisions relating to amendments to the Plan), a copy of which is
furnished to the Participant with this option.

spouse also accept the option. The following are community property states: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, and Washington. Although Wisconsin is not formally a community property state, it has laws governing the
division of marital property similar to community property states and it may be desirable to have a Wisconsin Participant’s spouse accept the option.

evaluate the risks involved in the purchase of the Shares and to make an informed investment decision with respect to such purchase. 
 4. I can afford a
complete loss of the value of the Shares and am able to bear the economic risk of holding such Shares for an indefinite period. 
 5. I understand that
(i) the Shares have not been registered under the Securities Act and are “restricted securities” within the meaning of Rule 144 under the Securities Act, (ii) the Shares cannot be sold, transferred or otherwise disposed of unless
they are subsequently registered under the Securities Act or an exemption from registration is then available; (iii) in any event, the exemption from registration under Rule 144 will not be available for at least one year and even then will not
be available unless a public market then exists for the Common Stock, adequate information concerning the Company is then available to the public, and other terms and conditions of Rule 144 are complied with; and (iv) there is now no
registration statement on file with the Securities and Exchange Commission with respect to any stock of the Company and the Company has no obligation or current intention to register the Shares under the Securities Act.

 PRODIGY SOFTWARE, INC. 

NONSTATUTORY STOCK OPTION AGREEMENT 

GRANTED UNDER 2015 STOCK INCENTIVE PLAN 

1. Grant of Option. 
 This Nonstatutory
Stock Option Agreement (the “Agreement”) evidences the grant by Prodigy Software, Inc., a Delaware corporation (the “Company”), on [________ __, 20__] (the “Grant Date”) to [___________], an
employee, consultant or director of the Company (the “Participant”), of an option to purchase, in whole or in part, on the terms provided herein and in the Company’s 2015 Stock Incentive Plan (the “Plan”), a
total of [___________] shares (the “Shares”) of common stock, $0.0001 par value per share, of the Company (“Common Stock”) at $[_________] per Share. Unless earlier terminated, this option shall expire at 5:00 p.m.,
Eastern time, on [________ __, 20__] [date is ten years minus one day from grant date] (the “Final Exercise Date”). 
 It
is intended that the option evidenced by this Agreement shall not be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”).
Except as otherwise indicated by the context, the term “Participant”, as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms. 

2. Vesting Schedule. 
 This option will
become exercisable (“vest”) as to 25% of the original number of Shares on the first anniversary of the Vesting Commencement Date (as defined below) and as to an additional 2.0833% of the original number of Shares at the end of each
successive month following the first anniversary of the Vesting Commencement Date until the fourth anniversary of the Vesting Commencement Date. On the fourth anniversary of the Vesting Commencement Date, this option will be
exercisable as to all Shares. For purposes of this Agreement, “Vesting Commencement Date” shall mean [__________________]. 

The right of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it
shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan. 

3. Exercise of Option. 
 (a) Form of
Exercise. Each election to exercise this option shall be accompanied by a completed Notice of Stock Option Exercise in the form attached hereto as Exhibit A, signed by the Participant, and received by the Company at its principal office, accompanied
by this Agreement, and payment in full in the manner provided in the Plan. The Participant may purchase less than the number of Shares covered hereby, provided that no partial exercise of this option may be for any fractional share or for fewer than
ten whole shares. 

 (b) Continuous Relationship with the Company Required. Except as otherwise provided
in this Section 3, this option may not be exercised unless the Participant, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor to, the
Company or any other entity the employees, officers, directors, consultants, or advisors of which are eligible to receive option grants under the Plan (an “Eligible Participant”). 

(c) Termination of Relationship with the Company. If the Participant ceases to be an Eligible Participant for any reason, then, except
as provided in paragraphs (d) and (e) below, the right to exercise this option shall terminate three months after such cessation (but in no event after the Final Exercise Date), provided that this option shall be exercisable only to the extent
that the Participant was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, violates the non-competition or
confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company, the right to exercise this option shall terminate immediately upon such violation. 

(d) Exercise Period Upon Death or Disability. If the Participant dies or becomes disabled (within the meaning of Section 22(e)(3)
of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for “cause” as specified in paragraph (e) below, this option shall be exercisable, within
the period of one year following the date of death or disability of the Participant, by the Participant (or in the case of death by an authorized transferee), provided that this option shall be exercisable only to the extent that this
option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final Exercise Date. 

(e) Termination for Cause. If, prior to the Final Exercise Date, the Participant’s employment or other relationship with the
Company is terminated by the Company for Cause (as defined below), the right to exercise this option shall terminate immediately upon the effective date of such termination of employment or other relationship. If, prior to the Final Exercise Date,
the Participant is given notice by the Company of the termination of his or her employment or other relationship by the Company for Cause, and the effective date of such employment or other termination is subsequent to the date of the delivery of
such notice, the right to exercise this option shall be suspended from the time of the delivery of such notice until the earlier of (i) such time as it is determined or otherwise agreed that the Participant’s employment or other
relationship shall not be terminated for Cause as provided in such notice or (ii) the effective date of such termination of employment or other relationship (in which case the right to exercise this option shall, pursuant to the preceding
sentence, terminate immediately upon the effective date of such termination of employment or other relationship). If the Participant is party to an employment, consulting or severance agreement with the Company that contains a definition of
“cause” for termination of employment or other relationship, “Cause” shall have the meaning ascribed to such term in such agreement. Otherwise, “Cause” shall mean willful misconduct by the Participant or willful failure
by the Participant to perform his or her responsibilities to the Company (including, without limitation, breach by the Participant of any provision of any employment, consulting, advisory, nondisclosure,
non-competition or other similar agreement between the Participant and the Company), as determined by the Company, which determination shall be conclusive. The Participant’s employment or other
relationship shall be considered to have been terminated for “Cause” if the Company determines, within 30 days after the Participant’s resignation, that termination for Cause was warranted. 

  
 -2- 

 4. Company Right of First Refusal. 

(a) Notice of Proposed Transfer. If the Participant proposes to sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by
operation of law or otherwise (collectively, “transfer”) any Shares acquired upon exercise of this option, then the Participant shall first give written notice of the proposed transfer (the “Transfer Notice”) to the
Company. The Transfer Notice shall name the proposed transferee and state the number of such Shares the Participant proposes to transfer (the “Offered Shares”), the price per share and all other material terms and conditions of the
transfer. 
 (b) Company Right to Purchase. For 30 days following its receipt of such Transfer Notice, the Company shall have the
option to purchase all or part of the Offered Shares at the price and upon the terms set forth in the Transfer Notice. In the event the Company elects to purchase all or part of the Offered Shares, it shall give written notice of such election to
the Participant within such 30-day period. Within 10 days after his or her receipt of such notice, the Participant shall tender to the Company at its principal offices the certificate or certificates
representing the Offered Shares to be purchased by the Company, duly endorsed in blank by the Participant or with duly endorsed stock powers attached thereto, all in a form suitable for transfer of the Offered Shares to the Company. Promptly
following receipt of such certificate or certificates, the Company shall deliver or mail to the Participant a check in payment of the purchase price for such Offered Shares; provided that if the terms of payment set forth in the
Transfer Notice were other than cash against delivery, the Company may pay for the Offered Shares on the same terms and conditions as were set forth in the Transfer Notice; and provided further that any delay in making such payment
shall not invalidate the Company’s exercise of its option to purchase the Offered Shares. 
 (c) Shares Not Purchased By Company.
If the Company does not elect to acquire all of the Offered Shares, the Participant may, within the 30-day period following the expiration of the option granted to the Company under subsection (b) above,
transfer the Offered Shares which the Company has not elected to acquire to the proposed transferee, provided that such transfer shall not be on terms and conditions more favorable to the transferee than those contained in the Transfer
Notice. Notwithstanding any of the above, all Offered Shares transferred pursuant to this Section 4 shall remain subject to the right of first refusal set forth in this Section 4 and such transferee shall, as a condition to such transfer,
deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Section 4. 

(d) Consequences of Non-Delivery. After the time at which the Offered Shares are required to be
delivered to the Company for transfer to the Company pursuant to subsection (b) above, the Company shall not pay any dividend to the Participant on account of such Offered Shares or permit the Participant to exercise any of the privileges or
rights of a stockholder with respect to such Offered Shares, but shall, insofar as permitted by law, treat the Company as the owner of such Offered Shares. 

  
 -3- 

 (e) Exempt Transactions. The following transactions shall be exempt from the
provisions of this Section 4: 
 (1) any transfer of Shares to or for the benefit of any spouse, child or grandchild of the Participant,
or to a trust for their benefit; 
 (2) any transfer pursuant to an effective registration statement filed by the Company under the
Securities Act of 1933, as amended (the “Securities Act”); and 
 (3) the sale of all or substantially all of the
outstanding shares of capital stock of the Company (including pursuant to a merger or consolidation); 
 provided, however, that in the case
of a transfer pursuant to clause (1) above, such Shares shall remain subject to the right of first refusal set forth in this Section 4.     

(f) Assignment of Company Right. The Company may assign its rights to purchase Offered Shares in any particular transaction under this
Section 4 to one or more persons or entities. 
 (g) Termination. The provisions of this Section 4 shall terminate upon the
earlier of the following events: 
 (1) the closing of the sale of shares of Common Stock in an underwritten public offering pursuant to an
effective registration statement filed by the Company under the Securities Act; or 
 (2) the sale of all or substantially all of the
outstanding shares of capital stock, assets or business of the Company, by merger, consolidation, sale of assets or otherwise (other than a merger or consolidation in which all or substantially all of the individuals and entities who were beneficial
owners of the Company’s voting securities immediately prior to such transaction beneficially own, directly or indirectly, more than 75% (determined on an as-converted basis) of the outstanding securities
entitled to vote generally in the election of directors of the resulting, surviving or acquiring corporation in such transaction). 
 (h)
No Obligation to Recognize Invalid Transfer. The Company shall not be required (1) to transfer on its books any of the Shares which shall have been sold or transferred in violation of any of the provisions set forth in this
Section 4, or (2) to treat as owner of such Shares or to pay dividends to any transferee to whom any such Shares shall have been so sold or transferred. 

(i) Legends. The certificate representing Shares shall bear a legend substantially in the following form (in addition to, or in
combination with, any legend required by applicable federal and state securities laws and agreements relating to the transfer of the Company securities): 

“The shares represented by this certificate are subject to a right of first refusal in favor of the Company, as provided in a certain
stock option agreement with the Company.” 

  
 -4- 

 5. Agreement in Connection with Initial Public Offering. 

The Participant agrees, in connection with the initial underwritten public offering of the Common Stock pursuant to a registration statement
under the Securities Act, (i) not to (a) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to
purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any other securities of the Company or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic
consequences of ownership of shares of Common Stock or other securities of the Company, whether any transaction described in clause (a) or (b) is to be settled by delivery of securities, in cash or otherwise, during the period beginning on the
date of the filing of such registration statement with the Securities and Exchange Commission and ending 180 days after the date of the final prospectus relating to the offering (plus up to an additional 34 days to the extent requested by the
managing underwriters for such offering in order to address NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4) or any similar successor provision), and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company
or the managing underwriters at the time of such offering. The Company may impose stop-transfer instructions with respect to the shares of Common Stock or other securities subject to the foregoing restriction until the end of the “lock-up” period. 
 6. Withholding. 

No Shares will be issued pursuant to the exercise of this option unless and until the Participant pays to the Company, or makes provision
satisfactory to the Company for payment of, any federal, state or local withholding taxes required by law to be withheld in respect of this option. 
 7.
Transfer Restrictions. 
 (a) This option may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant,
either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this option shall be exercisable only by the Participant. 

(b) The Participant agrees that he or she will not transfer any Shares issued pursuant to the exercise of this option unless the transferee, as
a condition to such transfer, delivers to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of Section 4 and Section 5; provided that such a written confirmation shall not be
required with respect to (1) Section 4 after such provision has terminated in accordance with Section 4(g) or (2) Section 5 after the completion of the lock-up period in connection
with the Company’s initial underwritten public offering.

that any reduction in duties, authority or responsibilities or reduction in the level of management to which the Participant reports resulting solely from a Change in Control which results in the Company being acquired by and made a part of a larger
entity shall not constitute Good Reason; provided, further, however, that no such events or conditions shall constitute Good Reason unless (x) the Participant gives the Company a written notice of termination for Good Reason not more
than ninety (90) days after the initial existence of the event or condition, (y) the grounds for termination, if susceptible to correction, are not corrected by the Company within thirty (30) days of its receipt of such notice and

Service over the [thirty-six (36)-month] period measured from the first anniversary of the Vesting Commencement Date.5

 (c) If[, within twelve (12) months] following a Change in Control, the
Participant’s Service is terminated (i) by the Company without Cause or (ii) by the Participant for Good Reason, then the vesting schedule of the Shares shall be accelerated such that [100%] of the Shares then subject to the Purchase
Option shall immediately become vested and free from the Purchase Option on the date of such termination.67 

Monthly Vesting, No Cliff: 
 All of the Shares shall
initially be subject to the Purchase Option. The Participant shall acquire a vested interest in, and the Company’s Purchase Option shall accordingly lapse with respect to the balance of the Shares in a series of successive equal monthly
installments of [1/48] of the Shares upon Participant’s completion of each additional month of Service over the [forty-eight (48)-month] period following the Vesting Commencement Date.  

Some, But Not All, Vested Shares at Signing: 
 [###] of
the Shares shall be fully vested as of the date hereof, and the balance of the Shares shall be subject to the Purchase Option. The Participant shall acquire a vested interest in, and the Company’s Purchase Option shall accordingly lapse with
respect to, (i) [###] shares on the Vesting Commencement Date and (ii) the balance of the Shares in a series of successive equal monthly installments of [1/48] of the Shares upon Participant’s completion of each additional month of Service
over the [forty-eight (48)-month] period following the Vesting Commencement Date. 
 Fully-Vested Shares: 

Use QuickStart form – Stock Purchase Agreement (Fully-Vested). 
  

Full Acceleration 
 Upon the consummation of a Change in
Control, the vesting schedule of the Shares shall be accelerated, and the Purchase Option shall accordingly lapse, such that one hundred percent (100%) of the original number of Shares shall immediately become vested and free from the Purchase
Option on the date of such Change in Control. 
 Partial Acceleration 

[This example assumes the original option grant had a four year vesting schedule with a 25% cliff on the first anniversary of the Vesting Commencement Date and
monthly vesting thereafter. This example provides for 25% partial acceleration upon a Change in Control and a reduction in the total vesting period from four years to three years with original cliff vesting concept retained in the case where the
Change of Control occurs prior to the one year cliff.] 
 Upon the consummation of a Change in Control, the vesting schedule of the Shares shall be
accelerated, and the Purchase Option shall accordingly lapse, such that the lesser of (i) 25% of the original number of Shares or (ii) all of the Shares that remain unvested hereunder, in each case shall immediately become vested and free form

 4. Exercise of Purchase Option and Closing. 

(a) The Company may exercise the Purchase Option by delivering or mailing to the Participant (or the Participant’s estate), within 180
days after the termination of the Service of the Participant, a written notice of exercise of the Purchase Option. Such notice shall specify the number of Shares to be purchased. If and to the extent the Purchase Option is not so exercised by the
giving of such a notice within such 180-day period, the Purchase Option shall automatically expire and terminate effective upon the expiration of such 180-day period.

 (b) Within ten (10) days after delivery to the Participant of the Company’s notice of the exercise of the Purchase Option
pursuant to subsection (a) above, the Participant (or the Participant’s estate) shall, pursuant to the provisions of the Joint Escrow Instructions referred to in Section 8 below, tender to the Company at its principal offices the
certificate or certificates representing the Shares that the Company has elected to purchase in accordance with the terms of this Agreement, duly endorsed in blank or with duly endorsed stock powers attached thereto, all in form suitable for the
transfer of such Shares to the Company. Promptly following its receipt of such certificate or certificates, the Company shall pay to the Participant the aggregate Option Price for such Shares (provided that any delay in making such payment shall not
invalidate the Company’s exercise of the Purchase Option with respect to such Shares). 
 (c) After the time at which any Shares are
required to be delivered to the Company for transfer to the Company pursuant to subsection (b) above, the Company shall not pay any dividend to the Participant on account of such Shares or permit the Participant to exercise any of the
privileges or rights of a stockholder with respect to such Shares, but shall, in so far as permitted by law, treat the Company as the owner of such Shares. 

(d) The Option Price may be payable, at the option of the Company, in cancellation of all or a portion of any outstanding indebtedness of the
Participant to the Company or in cash (by check) or both. 
  
  

Purchase Option on the date of such Change in Control. Thereafter, the Purchase Option shall accordingly lapse as follows: 

(i) if a Change in Control occurs prior to the [first] anniversary of the Vesting Commencement Date, then the Purchase Option shall lapse with respect to
(A) an additional 25%) of the original number of Shares on the first anniversary of the Vesting Commencement Date and (B) the remaining Shares in equal successive monthly installments following the first anniversary of the Vesting Commencement
Date (on the day of the month corresponding to the day of the month of the Vesting Commencement Date) until the third anniversary of the Vesting Commencement Date; or 

(ii) if a Change in Control occurs after the first anniversary of the Vesting Commencement Date, then then the Purchase Option shall lapse with respect to any
remaining Shares subject to the Purchase Option in equal successive monthly installments following the Change in Control (on the day of the month corresponding to the day of the month of the Vesting Commencement Date) until the third anniversary of
the Vesting Commencement Date. 

  
 - 4 - 

 (e) The Company shall not purchase any fraction of a Share upon exercise of the Purchase
Option, and any fraction of a Share resulting from a computation made pursuant to Section 3 of this Agreement shall be rounded to the nearest whole Share (with any one-half Share being rounded upward).

 (f) The Company may assign its Purchase Option to one or more persons or entities. 

5. Restrictions on Transfer. 

(a) The Participant shall not sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by operation of law or otherwise
(collectively “transfer”) any Shares, or any interest therein, that are subject to the Purchase Option, except that the Participant may transfer such Shares (i) to or for the benefit of any spouse, children, parents, uncles,
aunts, siblings, grandchildren and any other relatives approved by the Board of Directors (collectively, “Approved Relatives”) or to a trust established solely for the benefit of the Participant and/or Approved Relatives, provided
that such Shares shall remain subject to this Agreement (including without limitation the restrictions on transfer set forth in this Section 5, the Purchase Option and the right of first refusal set forth in Section 6) and such permitted
transferee shall, as a condition to such transfer, deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Agreement or (ii) as part of the sale of all or
substantially all of the shares of capital stock of the Company (including pursuant to a merger or consolidation), provided that, in accordance with the Plan, the securities or other property received by the Participant in connection with such
transaction shall remain subject to this Agreement. 
 (b) The Participant shall not transfer any Shares, or any interest therein, that are
no longer subject to the Purchase Option, except in accordance with Section 6 below. 
 6. Right of First Refusal. 

(a) If the Participant proposes to transfer any Shares that are no longer subject to the Purchase Option (either because they are free from the
Purchase Option pursuant to Section 3 or because the Purchase Option expired unexercised pursuant to Section 4), then the Participant shall first give written notice of the proposed transfer (the “Transfer Notice”) to the
Company. The Transfer Notice shall name the proposed transferee and state the number of such Shares the Participant proposes to transfer (the “Offered Shares”), the price per share and all other material terms and conditions of the
transfer. 
 (b) For 30 days following its receipt of such Transfer Notice, the Company shall have the option to purchase all or part of the
Offered Shares at the price and upon the terms set forth in the Transfer Notice. In the event the Company elects to purchase all or part of the Offered Shares, it shall give written notice of such election to the Participant within such 30-day period. Within 10 days after the Participant’s receipt of such notice, the Participant shall tender to the Company at its principal offices the certificate or certificates representing the Offered Shares
to be purchased by the Company, duly endorsed in blank by the Participant or with duly endorsed stock powers attached thereto, all in a form suitable for transfer of the Offered Shares 

  
 - 5 - 

 
to the Company. Promptly following receipt of such certificate or certificates, the Company shall deliver or mail to the Participant a check in payment of the purchase price for such Offered
Shares; provided that if the terms of payment set forth in the Transfer Notice were other than cash against delivery, the Company may pay for the Offered Shares on the same terms and conditions as were set forth in the Transfer Notice;
and provided further that any delay in making such payment shall not invalidate the Company’s exercise of its option to purchase the Offered Shares. 

(c) If the Company does not elect to acquire all of the Offered Shares, the Participant may, within the
30-day period following the expiration of the option granted to the Company under subsection (b) above, transfer the Offered Shares which the Company has not elected to acquire to the proposed transferee,
provided that such transfer shall not be on terms and conditions more favorable to the transferee than those contained in the Transfer Notice. Notwithstanding any of the above, all Offered Shares transferred pursuant to this
Section 6 shall remain subject to this Agreement (including without limitation the restrictions on transfer set forth in Section 5 and the right of first refusal set forth in this Section 6) and such transferee shall, as a condition
to such transfer, deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Agreement. 

(d) After the time at which the Offered Shares are required to be delivered to the Company for transfer to the Company pursuant to subsection
(b) above, the Company shall not pay any dividend to the Participant on account of such Offered Shares or permit the Participant to exercise any of the privileges or rights of a stockholder with respect to such Offered Shares, but shall,
insofar as permitted by law, treat the Company as the owner of such Offered Shares. 
 (e) The following transactions shall be exempt from
the provisions of this Section 6: 
 (1) a transfer of Shares to or for the benefit of any Approved Relatives, or to a trust
established solely for the benefit of the Participant and/or Approved Relatives; 
 (2) any transfer pursuant to an effective registration
statement filed by the Company under the Securities Act of 1933, as amended (the “Securities Act”); and 
 (3) the sale of
all or substantially all of the outstanding shares of capital stock of the Company (including pursuant to a merger or consolidation); 
 provided,
however, that in the case of a transfer pursuant to clause (1) above, such Shares shall remain subject to this Agreement (including without limitation the restrictions on transfer set forth in Section 5 and the right of first refusal set
forth in this Section 6) and such transferee shall, as a condition to such transfer, deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Agreement. 

(f) The Company may assign its rights to purchase Offered Shares in any particular transaction under this Section 6 to one or more persons
or entities. 

  
 - 6 - 

 (g) The provisions of this Section 6 shall terminate upon the earlier of the following
events: 
 (1) the closing of the sale of shares of Common Stock in an underwritten public offering pursuant to an effective registration
statement filed by the Company under the Securities Act; or 
 (2) a Change in Control. 

(h) The Company shall not be required (1) to transfer on its books any of the Shares which shall have been sold or transferred in
violation of any of the provisions set forth in this Agreement, or (2) to treat as owner of such Shares or to pay dividends to any transferee to whom any such Shares shall have been so sold or transferred. 

7. Agreement in Connection with Initial Public Offering. 

The Participant agrees, in connection with the initial underwritten public offering of the Common Stock pursuant to a registration statement
under the Securities Act, (i) not to (a) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to
purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock or (b) enter into any swap or other agreement that
transfers, in whole or in part, any of the economic consequences of ownership of shares of Common Stock, whether any transaction described in clause (a) or (b) is to be settled by delivery of shares of Common Stock or other securities, in cash
or otherwise, during the period beginning on the date of the filing of such registration statement with the Securities and Exchange Commission and ending 180 days from the date of the final prospectus relating to the offering (plus up to an
additional 34 days to the extent requested by the managing underwriters for such offering in order to address NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4) or any similar successor provision), and (ii) to execute any agreement reflecting clause
(i) above as may be requested by the Company or the managing underwriters at the time of such offering. The Company may impose stop-transfer instructions with respect to the shares of Common Stock or other securities subject to the foregoing
restriction until the end of the “lock-up” period. 
 8. Escrow. 

The Participant shall, upon the execution of this Agreement, execute Joint Escrow Instructions in the form attached to this Agreement as
Exhibit A. The Joint Escrow Instructions shall be delivered to the Secretary of the Company, as escrow agent thereunder. The Participant shall deliver to such escrow agent a stock assignment duly endorsed in blank, in the form attached to
this Agreement as Exhibit B, and hereby instructs the Company to deliver to such escrow agent, on behalf of the Participant, the certificate(s) evidencing the Shares issued hereunder. Such materials shall be held by such escrow agent pursuant
to the terms of such Joint Escrow Instructions. 

  
 - 7 - 

 9. Restrictive Legends. 

All certificates representing Shares shall have affixed thereto legends in substantially the following form, in addition to any other legends
that may be required under federal or state securities laws: 
 “The shares of stock represented by this certificate
are subject to restrictions on transfer and an option to purchase set forth in a certain Restricted Stock Agreement between the corporation and the registered owner of these shares (or such owner’s predecessor in interest), and such Agreement
is available for inspection without charge at the office of the Secretary of the corporation.” 
 “The shares
represented by this certificate have not been registered under the Securities Act of 1933, as amended, and may not be sold, transferred or otherwise disposed of in the absence of an effective registration statement under such Act or an opinion of
counsel satisfactory to the corporation to the effect that such registration is not required.” 
 10. Provisions of the Plan.

 This Agreement is subject to the provisions of the Plan, a copy of which is furnished to the Participant with this Agreement. 

11. Investment Representations. 

The Participant represents, warrants and covenants as follows: 

(a) The Participant is purchasing the Shares for Participant’s own account for investment only, and not with a view to, or for sale in
connection with, any distribution of the Shares in violation of the Securities Act, or any rule or regulation under the Securities Act. 

(b) The Participant has had such opportunity as Participant has deemed adequate to obtain from representatives of the Company such information
as is necessary to permit him to evaluate the merits and risks of Participant’s investment in the Company. 
 (c) The Participant has
sufficient experience in business, financial and investment matters to be able to evaluate the risks involved in the purchase of the Shares and to make an informed investment decision with respect to such purchase. 

(d) The Participant can afford a complete loss of the value of the Shares and is able to bear the economic risk of holding such Shares for an
indefinite period. 
 (e) The Participant understands that (i) the Shares have not been registered under the Securities Act and are
“restricted securities” within the meaning of Rule 144 under the Securities Act; (ii) the Shares cannot be sold, transferred or otherwise disposed of unless they are subsequently registered under the Securities Act or an exemption
from registration is then available; (iii) in any event, the exemption from registration under Rule 144 will not be available 

  
 - 8 - 

 
for at least one year and even then will not be available unless a public market then exists for the Common Stock, adequate information concerning the Company is then available to the public, and
other terms and conditions of Rule 144 are complied with; and (iv) there is now no registration statement on file with the Securities and Exchange Commission with respect to any stock of the Company and the Company has no obligation or current
intention to register the Shares under the Securities Act. 
 12. Withholding Taxes; Section 83(b) Election. 

(a) The Participant acknowledges and agrees that the Company has the right to deduct from payments of any kind otherwise due to the Participant
any federal, state or local taxes of any kind required by law to be withheld with respect to the purchase of the Shares by the Participant or the lapse of the Purchase Option. 

(b) The Participant has reviewed with the Participant’s own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Participant understands that the Participant
(and not the Company) shall be responsible for the Participant’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. The Participant understands that it may be beneficial in many
circumstances to elect to be taxed at the time the Shares are granted by the Company rather than when and as the Company’s Purchase Option expires by filing an election under Section 83(b) of the Internal Revenue Code of 1986 with the
I.R.S. within 30 days from the date of grant by the Company. 
 THE PARTICIPANT ACKNOWLEDGES THAT IT IS SOLELY THE PARTICIPANT’S
RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF THE PARTICIPANT REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON THE PARTICIPANT’S BEHALF. 

13. Miscellaneous. 
 (a)
No Rights to Employment. The Participant acknowledges and agrees that the vesting of the Shares pursuant to Section 3 hereof is earned only by the Participant’s continuous Service (not through the act of being hired or purchasing
the Shares hereunder). The Participant further acknowledges and agrees that the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of continued engagement as an employee or
consultant for the vesting period, for any period, or at all. 
 (b) Severability. The invalidity or unenforceability of any provision
of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, and each other provision of this Agreement shall be severable and enforceable to the extent permitted by law. 

  
 - 9 - 

 (c) Waiver. Any provision for the benefit of the Company contained in this Agreement
may be waived, either generally or in any particular instance, by the Board of Directors of the Company. 
 (d) Binding Effect. This
Agreement shall be binding upon and inure to the benefit of the Company and the Participant and their respective heirs, executors, administrators, legal representatives, successors and assigns, subject to the restrictions on transfer set forth in
Sections 5 and 6 of this Agreement. 
 (e) Notice. All notices required or permitted hereunder shall be in writing and deemed
effectively given upon personal delivery or five days after deposit in the United States Post Office, by registered or certified mail, postage prepaid, addressed to the other party hereto at the address shown beneath his or her or its respective
signature to this Agreement, or at such other address or addresses as either party shall designate to the other in accordance with this Section 13(e). 

(f) Pronouns. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine
or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa. 
 (g) Entire Agreement. This
Agreement and the Plan constitute the entire agreement between the parties, and supersedes all prior agreements and understandings, relating to the subject matter of this Agreement. 

(h) Amendment. This Agreement may be amended or modified only by a written instrument executed by both the Company and the Participant.

 (i) Governing Law. This Agreement shall be construed, interpreted and enforced in accordance with the internal laws of the State of
Delaware without regard to any applicable conflict of law principles. 
 (j) Participant’s Acknowledgments. The Participant
acknowledges that he or she: (i) has read this Agreement; (ii) has been represented in the preparation, negotiation, and execution of this Agreement by legal counsel of the Participant’s own choice or has voluntarily declined to seek
such counsel; (iii) understands the terms and consequences of this Agreement; (iv) is fully aware of the legal and binding effect of this Agreement; and (v) understands that the law firm of WilmerHale is acting as counsel to the
Company in connection with the transactions contemplated by the Agreement, and is not acting as counsel for the Participant.

 SECTION 83(B) ELECTION 

BACKGROUND INFORMATION 

Section 83(b) of the Internal Revenue Code permits persons who receive restricted property, such as restricted stock, in connection with
the performance of services to include the value of such property in their gross income for the year the property is received. Such persons who purchase stock of the company subject to a stock restriction agreement providing for the vesting of such
stock over a period of time are entitled to make this election. Any person who makes a timely Section 83(b) election will recognize compensation income on the date of grant (the date listed in item 3 of the election form) equal to the
difference, if any, between the fair market value of the stock and the amount paid for the stock. A person who pays taxes in connection with an election and subsequently forfeits the stock, however, will not receive a refund or other tax benefit for
the taxes previously paid. 
 Any person who does not make the election will be required to include the value of the stock in gross income
in the year in which the stock vests. In particular, when the stock vests, the person will recognize compensation income in an amount equal to the difference between the fair market value of the stock on the vesting date and the amount paid for the
stock. As a result, if the value of the stock increases, a person who does not make a timely Section 83(b) election will have compensation income at the time each installment of stock vests. 

Each person should consult with his or her tax or legal advisor regarding the advisability and timing of filing the election. The original,
signed and dated Section 83(b) election must be filed within 30 days of the grant date but may be filed prior to the grant date. The election should be filed by certified mail, return receipt requested, with the Internal
Revenue Service at the service center where the electing person ordinarily files his or her annual tax return. A copy of the Section 83(b) election, as filed, must be returned to the company. A copy of the Section 83(b) election must also
be included with the person’s federal income tax return for the year of grant (each person should check with his or her tax preparer regarding this and any state, local, foreign or other filing requirements). 

Please also note that the certified mailing receipt for the Section 83(b) election should be retained. This receipt is essential if
the Internal Revenue Service does not receive the Section 83(b) election and challenges the election.Exhibit 4.2

with the provisions of this Section 1.2. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition
of all or any portion of the Restricted Securities, or any beneficial interest therein, unless and until (x) the transferee thereof

owners or retired partners, retired members or other equity owners, or (iii) transfers in compliance with Rule 144, as long as

Holder thereof shall give written notice to the Company of such Holder's intention to effect such disposition and shall have furnished

“THE SHARES
REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED,
PLEDGED, OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT, OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL OR
OTHER EVIDENCE, IF REQUESTED, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.”

 

“THE SHARES
REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN INVESTORS’ RIGHTS AGREEMENT BETWEEN THE COMPANY
AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.”

 

The Holders consent to
the Company making a notation on its records and giving instructions to any transfer agent of the Restricted Securities in order

first legend referring to federal and state securities laws identified in Section 1.2(c) hereof stamped on a certificate evidencing
the Restricted Securities and the stock transfer instructions and record notations with respect to such Restricted Securities
shall be removed and the Company shall issue a certificate without such legend to the holder of such Restricted Securities if
(i) such securities are registered under the Securities Act, (ii) such holder provides the Company with an opinion of counsel
reasonably acceptable to the Company to the effect that a public sale or transfer of such securities may be made without registration
under the Securities Act, or (iii) such holder provides the Company with reasonable assurances, which may, at the option of the
Company, include an opinion of counsel satisfactory to the Company, that such securities can be sold pursuant to Rule 144 under
the Securities Act.

 

    4

     

    

 

1.3           Request
for Registration.

 

(a)                 Subject
to the conditions of this Section 1.3, if the Company shall receive at any time after the earlier of the date that is (i) three
(3) years after the date of this Agreement or (ii) six months following the effective date of the registration statement pertaining
to the IPO, a written request pursuant to this Section 1.3 from Holders of at least 35% of the Registrable Securities then
outstanding (assuming conversion of all Preferred Stock and exercise of the Common Warrants) (the “Initiating Holders”)
that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities which
would have an aggregate offering price of not less than $5,000,000, the Company shall within twenty (20) days of the receipt thereof,
give written notice of such request to all Holders, and subject to the limitations of this Section 1.3, use its best efforts to
effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Holders request
to be registered in a written request received by the Company within twenty (20) days of the mailing of the Company’s notice
pursuant to this Section 1.3(a).

 

(b)                If
the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they
shall so advise the Company as a part of their request made pursuant to Section 1.3(a) and the Company shall include such information
in the written notice referred to in Section 1.3(a). The underwriter will be selected by the Company and shall be reasonably acceptable
to a majority in interest of the Initiating Holders. In such event, the right of any Holder to include its Registrable Securities
in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such
Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their
securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting. Notwithstanding any other provision of this Section 1.3, if the underwriter determines in
good faith that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise
all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares of Registrable
Securities that may be included in the underwriting shall be allocated, first, to the Initiating Holders on a pro rata
basis based on the total number of Registrable Securities held by the Initiating Holders; and second, to any Holder on a pro
rata basis among all such Holders; provided, however, that if as a result of any such cutback fewer than fifty-percent
(50%) of the total number of Registrable Securities that have been requested by Holders of Registrable Securities to be included
in such registration statement are actually included, than such registration statement shall not be counted as “effected”
for purposes of this Section 1.3 (including for purposes of Section 1.3(d)(i)), notwithstanding the obligation of the Company
to proceed with the offering.

 

(c)                Notwithstanding
the foregoing, if the Company shall furnish to the Holders requesting a registration statement pursuant to this Section 1.3 a
certificate signed by the Chief Executive Officer of the Company (“Chief Executive Officer”) stating
that, in the good faith judgment of the Board of Directors of the Company (the “Board of Directors”),
it would be materially detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore
essential to defer the filing of such registration statement, then the Company shall have the right to defer taking action with
respect to such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders;
provided, however, that the Company may not utilize this right more than once in any twelve (12) month period; and, provided,
further, that the Company shall not register any securities for its own account or that of any other stockholders during such
ninety (90) day period other than (i) a registration relating to the sale of securities to employees of the Company or a subsidiary
pursuant to a stock option, stock purchase, or similar plan; (ii) a registration relating to an SEC Rule 145 transaction; (iii)
a registration on any form that does not include substantially the same information as would be required to be included in a registration
statement covering the sale of the Registrable Securities; or (iv) a registration in which the only Common Stock being registered
is Common Stock issuable upon conversion of debt securities that are also being registered.

 

    5

     

    

 

(d)            In
addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section
1.3:

 

(i)          after
the Company has effected two (2) registrations pursuant to this Section 1.3 and such registrations have been declared or ordered
effective;

 

(ii)         during
the six-month period following the effective date of the registration statement pertaining to the IPO; or

 

(iii)        if,
within thirty (30) days of a registration request by the Initiating Holders, the Company gives notice to the Holders of its
intent to file a registration statement for its IPO within ninety (90) days.

 

1.4           Company
Registration.

 

(a)                 If
(but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by
the Company for stockholders other than the Holders) any of its stock or other securities under the Securities Act in connection
with the public offering of such securities solely for cash (other than a registration relating solely to the sale of securities
to participants in a Company stock plan, any registration statements relating to any corporate reorganization or transaction under
Rule 145 of the Securities Act or any registration statements related to the issuance or resale of securities issued in such a
transaction or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt
securities which are also being registered), the Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within ten (10) days after mailing of such notice by the Company in
accordance with Section 5.6, the Company shall, subject to the provisions of Section 1.4(b), cause to be registered under the
Securities Act all of the Registrable Securities that each such Holder has requested to be registered. Registrations effected
pursuant to this Section 1.4 shall not be counted as demands for registration pursuant to Section 1.3 or registrations pursuant
to Section 1.5.

 

(b)                 If
the registration statement under which the Company gives notice under this Section 1.4 is for an underwritten offering, the Company
shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration
pursuant to this Section 1.4 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion
of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute
their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter
or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Agreement, if the underwriter
determines in good faith that marketing factors require a limitation of the number of shares to be underwritten, the number of
shares that may be included in the underwriting shall be allocated, first, to the Company; second, to the Holders on a pro
rata basis based on the total number of Registrable Securities held by the Holders; and third, to any stockholder of the Company
(other than a Holder) on a pro rata basis. No such reduction shall reduce the amount of securities of the selling Holders
included in the registration below twenty-five percent (25%) of the total amount of securities included in such registration,
unless such offering is the IPO and such registration does not include shares of any other selling stockholders, in which event
any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding sentence.
For any Holder which is a partnership or corporation, the partners, retired partners and shareholders of such Holder, or the estates
and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall
be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall
be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such
 “Holder,” as defined in this sentence.

 

    6

     

    

 

(c)                The
Company shall have the right to terminate or withdraw any registration initiated by it under this Section 1.4 prior to the effectiveness
of such registration whether or not any Holder has elected to include securities in such registration.

 

1.5           Form
S-3 Registration. In case the Company shall receive from any Holders of a majority of the then outstanding Registrable Securities
(assuming conversion of all Preferred Stock and exercise of the Common Warrants) a written request or requests that pursuant to
this Section 1.5 the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all
or a part of the Registrable Securities owned by such Holder or Holders, the Company will:

 

(a)               promptly
give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and

 

(b)               use its best efforts to effect such registration and all such qualifications and compliances as may be so requested
and as would permit or facilitate the sale and distribution of all or such portion of such Holders’ Registrable Securities
as are specified in such request, together with all or such portion of the Registrable Securities of any other Holders joining
in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from
the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 1.5: (i) if Form S-3 is not available for such offering by the Holders; (ii) if the Holders
propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than $1,000,000;
(iii) if, in a given twelve-month period, the Company has already effected two (2) such registrations pursuant to this Section
1.5 in such period; (iv) if the Company shall furnish to the Holders a certificate signed by the President of the Company stating
that in the good faith judgment of the Board of Directors, it would be materially detrimental to the Company and its stockholders
for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, in
which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more
than ninety (90) days after receipt of the request of the Holder or Holders under this Section 1.5; provided, however, that
the Company shall not utilize this right more than once in any twelve (12) month period; or (v) in any particular jurisdiction
in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting
such registration, qualification or compliance or otherwise subject itself to general taxation. Subject to the foregoing, the Company
shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon
as practicable after receipt of the request or requests of the Holders. Registrations effected pursuant to this Section 1.5 shall
not be counted as demands for registration effected pursuant to Section 1.3.

 

1.6           Obligations
of the Company.  Whenever required under this Section 1 to effect the registration of any Registrable Securities, the
Company shall, as expeditiously as reasonably possible:

 

(a)                 Prepare
and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for a period of up to 120 days, or if earlier, until the distribution contemplated
in the registration statement has been completed.

 

    7

     

    

 

(b)                Prepare
and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with
such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement.

 

(c)                Furnish
to the Holders of Registrable Securities registered thereunder such numbers of copies of a prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

 

(d)                Use
its best efforts to register and qualify the securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders of Registrable Securities registered thereunder;
provided, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business
or to file a general consent to service of process, or subject itself to general taxation, in any such states or jurisdictions.

 

(e)                In
the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder of Registrable Securities registered thereunder
participating in such underwriting shall also enter into and perform its obligations under such an agreement.

 

(f)                Notify
each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act or the happening of any event as a result of which the prospectus included in
such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then
existing.

 

(g)               Cause
all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange or nationally recognized
quotation system on which similar securities issued by the Company are then listed.

 

(h)               Provide
a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable
Securities, in each case not later than the effective date of such registration.

 

(i)                Cooperate
in all necessary respects with (A) counsel in preparation of the customary legal opinions and (B) accountants in preparation of
the customary comfort letters, copies of which shall be provided to each Holder of Registrable Securities registered thereunder
so requesting; provided that such Holders shall not be entitled to rely upon such legal opinions and comfort letters other than
in accordance with their own respective terms.

 

(j)                Promptly
make available for inspection by the Holders of Registrable Securities registered thereunder, any managing underwriter(s)
participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent
retained by any such underwriter or selected by the Holders of Registrable Securities registered thereunder, all financial and
other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors,
employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney,
accountant, or agent, in each case, as necessary or advisable
to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection
therewith.

 

    8

     

    

 

1.7           Furnish
Information.

 

(a)                 It
shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 with respect to
the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect
the registration of such Holder’s Registrable Securities.

 

(b)                 The
Company shall have no obligation with respect to any registration requested pursuant to Section 1.3 or Section 1.5 if, due to
the operation of Section 1.7(a), the number of shares of the Registrable Securities to be included in the registration does
not equal or exceed the number of shares required to originally trigger the Company’s obligation to initiate such registration
as specified in Section 1.3(a) or Section 1.5(b), as the case may be.

 

1.8           Expenses
of Registration. All expenses, other than underwriting discounts, transfer taxes and commissions incurred by the selling Holders
in connection with registrations, shall be paid or reimbursed by the Company for filings or qualifications pursuant to Section
1.3, Section 1.4 and Section 1.5, including (without limitation) all registration, filing and qualification fees, printers’
and accounting fees, fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one counsel
for the selling Holders (collectively, the “Registration Expenses”); provided, however, that
the Company shall not be required to pay for any Registration Expenses of any registration proceeding begun pursuant to Section
1.3(a) or Section 1.5 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered unless (a) the withdrawal is based upon material adverse information concerning the Company
of which the Initiating Holders or Holders, as applicable, were not aware at the time of such request or (b) the Holders of a
majority of Registrable Securities to be registered agree to deem such registration to have been effected as of the date of such
withdrawal for purposes of determining whether the Company shall be obligated pursuant to Section 1.3 to undertake any subsequent
registration, in which event such right shall be forfeited by all Holders. If the Holders are required to pay the Registration
Expenses, such expenses shall be borne pro rata based upon the number of Registrable Securities that were to be registered
in the withdrawn registration.

 

1.9           Delay
of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 1.

 

1.10        Indemnification.
In the event any Registrable Securities are included in a registration statement under this Section 1:

 

(a)                 To
the fullest extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers,
directors, stockholders and former stockholders of each Holder, any underwriter (as defined in the Securities Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages or liabilities (joint or several) to which they may become subject under the Securities Act,
the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”):
(i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading,
or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or
any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law; and the Company will
pay to each such Holder, underwriter or controlling person any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability or action, as such expenses are incurred; provided,
however, that the indemnity agreement contained in this Section 1.10(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability
or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with
written information relating to any such Holder and furnished expressly for inclusion in a registration statement in connection
with such registration by such Holder, the partners, members, officers, directors and stockholders of such Holder, the underwriter
for such Holder or a controlling person of such Holder and; provided further, however, that the foregoing indemnity agreement
with respect to any preliminary prospectus shall not inure to the benefit of any Holder, partners, members, officers, directors
and stockholders of any Holder, or any underwriter for such Holder, or any person controlling such Holder, from whom the person
asserting any such losses, claims, damages or liabilities purchased shares in the offering, if a copy of the prospectus (as then
amended or supplemented) was not sent or given by or on behalf of such Holder or underwriter to such person, if required by law
so to have been delivered by such Holder, at or prior to the written confirmation of the sale of the shares to such person, and
if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability.

 

    9

     

    

 

(b)                To
the extent permitted by law, each selling Holder, severally, and not jointly, will indemnify and hold harmless the Company, each
of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company
within the meaning of the Securities Act, any underwriter, any other Holder selling securities in such registration statement
and any controlling person of any such underwriter or other Holder, against any losses, claims, damages or liabilities to which
any of the foregoing persons may become subject, under the Securities Act, the Exchange Act or other federal or state law, insofar
as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information
relating to such Holder and furnished by such Holder expressly for use in connection with such registration; and each such Holder
will pay any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this Section 1.10(b),
in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that
the indemnity agreement contained in this Section 1.10(b) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be
unreasonably withheld, provided that in no event shall any indemnity under this Section 1.10(b) exceed the net proceeds from
the offering received by such Holder (including net of any underwriting discounts, selling commissions, and stock transfer taxes
applicable to the sale of Registrable Securities).

 

(c)                Promptly
after receipt by an indemnified party under this Section 1.10 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party
under this Section 1.10, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party
shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel)
shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation
of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure
to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial
to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this
Section 1.10, but the omission to so deliver written notice to the indemnifying party will not relieve it of any liability that
it may have to any indemnified party otherwise than under this Section 1.10.

 

    10

     

    

 

(d)                If
the indemnification provided for in this Section 1.10 is held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage or expense referred to therein, then the indemnifying party, in lieu
of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as
a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault
of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions
that resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations; provided,
that, in no event shall any contribution under this Section 1.10(d) by a Holder exceed the net proceeds from the offering received
by such Holder (including net of any underwriting discounts, selling commissions, and stock transfer taxes applicable to the sale
of Registrable Securities). The relative fault of the indemnifying party and of the indemnified party shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material
fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission.

 

(e)                Notwithstanding
the foregoing, to the extent that the provisions on indemnification and contribution between the Company and underwriter contained
in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing
provisions, the provisions in the underwriting agreement shall control.

 

(f)                The
obligations of the Company and Holders under this Section 1.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1.

 

1.11        Reports
Under Securities Exchange Act of 1934. With a view to making available to the Holders the benefits of Rule 144 promulgated
under the Securities Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of
the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to:

 

(a)                make
and keep public information available, as those terms are understood and defined in Rule 144, at all times after ninety (90) days
after the effective date of the IPO;

 

(b)                file
with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange
Act; and

 

    11

     

    

 

(c)               furnish
to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company
that it has complied with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date
of the first registration statement filed by the Company), the Securities Act and the Exchange Act (at any time after it has become
subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form
S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any
Holder of any rule or regulation of the SEC which permits the selling of any such-securities without registration or pursuant
to such form.

 

1.12         Assignment
of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 1 may
be assigned (but only with all related obligations) by (i) a Holder that is a partnership, to any partner, retired partner or
affiliated fund of such Holder, (ii) a Holder that is a limited liability company or a corporation, to any member or former member
or stockholder of such Holder, (iii) a Holder who is an individual, to such Holder’s family member or trust for the benefit
of such Holder or such Holder’s family member, (iv) a Holder that transfers all shares of Registrable Securities held by
he, she or it, or (v) to any other person acquiring at least 500,000 shares (or not less than all of such Holder’s Registrable
Securities, if such Holder holds less than 500,000 Registrable Securities) (as appropriately adjusted for any stock split, dividend,
combination or other recapitalization or like transactions) of Registrable Securities; provided (in all cases) (a) the Company
is, promptly after such transfer, furnished with written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned; (b) such transferee or assignee agrees in writing
to be bound by and subject to the terms and conditions of this Agreement, including without limitation the provisions of Section
2 below; and (c) such assignment shall be effective only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Securities Act.

 

1.13         
Termination of Registration Rights. All registration rights granted under this Section 1 shall terminate and be of no
further force and effect upon the earlier of (i) four (4) years after the consummation of the IPO, or (ii) the effective date
of a Change of Control pursuant to which the Holders receive cash or securities traded on a nationally recognized securities exchange.
In addition, a Holder’s registration rights under this Section 1 shall expire at such time as all Registrable Securities
held by such Holder (together with any affiliates of such Holder with whom such Holder must aggregate its sales under Rule 144)
can be sold in any three (3) month period without registration under Rule 144.

 

1.14         
Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without
the prior written consent of the Holders of a majority of the Registrable Securities then outstanding (assuming conversion of all
Preferred Stock and exercise of the Common Warrants) and the approval of a majority of the Board of Directors, enter into any agreement
with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder to include
such securities in any registration filed under Section 1.3 hereof, unless under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce
the amount of the Registrable Securities of the Holders which is included.

 

    12

     

    

 

2.              “Market
Stand-Off” Agreement. Each Holder hereby agrees that such Holder shall not sell, transfer, make any short sale of,
grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a
sale of, any Common Stock (or other securities) of the Company held by such Holder (other than those included in the
registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the
Company not to exceed one hundred eighty (180) days following the effective date of a registration statement of the Company
filed under the Securities Act in connection with the Company’s IPO (such period of time, the “Lockup
Period”), provided that all officers and directors of the Company and holders of at least one percent (1%) of
the Company’s voting securities (on an as-converted to Common Stock basis) are bound by and have entered into similar
agreements. The foregoing provisions of this Section 2 shall apply only to the IPO, and shall not apply to the sale of
any shares to an underwriter pursuant to an underwriting agreement, or any shares purchased in connection with the IPO or on
the open market following the IPO. Each Holder agrees to execute and deliver such other
agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which
are necessary to give further effect thereto. The Company may impose stop-transfer instructions with respect to the shares of
Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day
period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 2 and shall have
the right, power and authority to enforce the provisions hereof as though they were a party hereto. Any discretionary waiver
or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata
to all Company stockholders that are subject to such agreements, based on the number of shares subject to such
agreements.

 

3.            
Covenants of the Company.

 

3.1          
Delivery of Financial Statements to Investors. So long as an Investor holds at least 20,000,000 shares (as adjusted
for stock splits, combinations, reorganizations and the like) of Registrable Securities (a “Major Investor”),
the Company shall deliver to such Major Investor:

 

(a)               
as soon as practicable, but in any event within one hundred twenty (120) days after the end of each fiscal year of the
Company, an income statement for such fiscal year, a balance sheet of the Company and statement of stockholder’s equity as
of the end of such fiscal year, and a statement of cash flows for such fiscal year, such year-end financial reports to be in reasonable
detail, prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States,
and audited and certified by independent public accountants of nationally recognized standing selected by the Board of Directors,
and accompanied by a certificate executed by the chief financial officer of the Company (in the event of no Company chief financial
officer then by the Chief Executive Officer) certifying that such financial statements fairly present the financial condition of
the Company and its results of operations for the periods specified therein; and

 

(b)              
as soon as practicable, but in any event within forty-five (45) days after the end of each of the first three fiscal
quarters of each fiscal year of the Company, an unaudited income statement, a statement of cash flows and an unaudited balance
sheet for such quarter, prepared in accordance with GAAP (except that such financial statements may (i) be subject to normal year-end
audit adjustments and (ii) not contain all notes thereto that may be required in accordance with GAAP), and accompanied by a certificate
executed by the chief financial officer of the Company (in the event of no Company chief financial officer then by the Chief Executive
Officer) certifying that such financial statements fairly present the financial condition of the Company and its results of operations
for the periods specified therein;

 

(c)               
as soon as practicable, but in any event thirty (30) days prior to the beginning of each fiscal year an annual budget
and operating plans for such fiscal year, prepared on a monthly basis, and, as soon as prepared, any other budgets or revised budgets
prepared by the Company;

 

(d)              
upon request, a detailed capitalization table of the Company; and

 

    13

     

    

 

(e)               
 upon the request of a Major Investor, such additional information and materials as the Major Investor may reasonably
request, and the Chief Executive Officer may consent to provide, such consent not to be unreasonably withheld, including documents
of the Company’s management, reports of operations, reports of adverse developments, copies of any management letters, and
stockholder communications.

 

3.2           Inspection.
The Company shall permit each Major Investor, at such Major Investor’s expense, to visit and inspect the Company’s
properties, to examine its books of account and records and to discuss the Company’s affairs, finances and accounts with
its officers, all at such reasonable times as may be convenient to the Company and such Major Investor; provided, however,
that the Company shall not be obligated pursuant to this Section 3.2 to provide access to any information that it reasonably considers
to be a trade secret or similar confidential information (unless covered by a confidentiality agreement, in form and substance
reasonably acceptable to the Company) or the disclosure of which would adversely affect the attorney-client privilege between
the Company and its counsel.

 

3.3           Confidentiality
of Records. Each Investor agrees to use the same degree of care as such Investor uses to protect its own confidential information
but in no event less than a reasonable degree of care, to keep confidential any information furnished to it that the Company identifies
as being confidential or proprietary (so long as such information is not in the public domain) and to keep confidential any confidential
information, knowledge or data concerning or relating to the business or financial affairs of the Company which such Investor
has been or shall become privy by reason of this Agreement, except that such Investor may disclose such proprietary or confidential
information (i) to any existing or prospective partner, affiliate (excluding portfolio companies), subsidiary, parent or member
of such Investor for the purpose of evaluating its investment in the Company as long as such existing or prospective partner,
affiliate (excluding portfolio companies), subsidiary, parent or member is advised of the confidentiality provisions of this Section
3.3 and is directed by such Investor to maintain the confidentiality of such information; (ii) to its attorneys, accountants,
consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment
in the Company, as long as such attorney, accountant, consultant or other professional is bound to the Investor to keep such information
confidential by industry standards or ethical rules (such as those applicable to attorney and accountants) or provisions at least
as stringent as those contained in this Section 3.3; (iii) to any prospective purchaser of any Registrable Securities from such
Investor, if such prospective purchaser agrees to be bound by the provisions of this Section 3.3; (iii) at such time as it enters
the public domain through no fault of such Investor; (iv) that is communicated to it free of any obligation of confidentiality;
(v) that is developed by Investor or its agents independently of and without reference to any confidential information communicated
by the Company; or (vi) as may otherwise be required by law, provided, however, that the Investor promptly notifies the
Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure.

 

3.4          Right
of First Offer. Subject to the terms and conditions specified in this Section 3.4, the Company hereby grants to each Major
Investor a right of first offer with respect to future sales by the Company of its Shares. A Major Investor shall be entitled
to apportion the right of first offer hereby granted it among itself and its partners and affiliates in such proportions as it
deems appropriate; provided, that any such partner or affiliate shall, if not already a party, agree to become a party
to this Agreement as an “Investor” hereunder.

 

Each time following
the date hereof that the Company proposes to offer any shares of, or securities convertible into or exchangeable or exercisable
for any shares of, any class of its capital stock (“Shares”), the Company shall first make an offering
of such Shares to each Major Investor in accordance with the following provisions.

 

    14

     

    

 

(a)              The Company shall deliver a notice in accordance with Section 5.6 to the Major Investors stating (i) its bona fide
intention to offer such Shares, (ii) the number of such Shares to be offered, and (iii) the price and terms upon which it proposes
to offer such Shares.

 

(b)            
By written notification received by the Company, within fifteen (15) calendar days after delivery of the notice, the
Major Investor may elect to purchase or obtain, at the price and on the terms specified in the notice, up to that portion of such
Shares that equals the proportion that the number of shares of Common Stock deemed to be held by such Major Investor (including
all shares of Common Stock issuable or issued upon conversion of the Preferred Stock or upon the exercise of outstanding warrants
or options) bears to the total number of shares of Common Stock of the Company then outstanding (including all shares of Common
Stock issuable or issued upon conversion of the Preferred Stock or upon the exercise of outstanding warrants or options). The Company
shall promptly, in writing, inform each Major Investor that elects to purchase all the shares available to it (a “Fully-Exercising
Investor”) of any other Major Investor’s failure to do likewise. During the ten (10) day period commencing
after such information is given, each Fully-Exercising Investor may elect to purchase that portion of the Shares for which Major
Investors were entitled to subscribe but which were not subscribed for that is equal to the proportion that the number of shares
of Common Stock issued and held, or issuable upon conversion of Preferred Stock then held, by such Fully-Exercising Investor bears
to the total number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, by
all Fully-Exercising Investors who wish to purchase some of the unsubscribed shares.

 

(c)           
If all Shares that Major Investors are entitled to obtain pursuant to Section 3.4(b) are not elected to be obtained
as provided in Section 3.4(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period
provided in Section 3.4(b) hereof, offer the remaining unsubscribed portion of such Shares to any person or persons at a price
not less than, and upon terms no more favorable to the offeree than those specified in the notice. If the Company does not enter
into an agreement for the sale of the Shares within such period, or if such agreement is not consummated within ninety (90) days
of the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless
first reoffered to the Major Investors in accordance herewith.

 

(d)           
The right of first offer in this Section 3.4 shall not be applicable to:

 

(i)                
the issuance of Series F Preferred Stock as part of the Financing;

 

(ii)              
the issuance of Common Stock upon the conversion of Convertible Securities (as defined in the Restated Certificate)
or shares of Preferred Stock, and capital stock issued pursuant to any such rights or agreements granted after the date of this
Agreement, so long as the rights of first offer established by this Section 3.4 were complied with, waived or inapplicable pursuant
to any provisions of this section 3.4(d);

 

(iii)            
shares of Common Stock issued or issuable by reason of a dividend, stock split, split-up or other distribution on shares
of Common Stock that is covered by Section 3(f) or Section 3(g) of Article FOURTH, Part C of the Restated Certificate and shares
of Common Stock issued or deemed issued as a dividend or Distribution (as defined in the Restated Certificate) on Preferred Stock;

 

(iv)              the
issuance of Common Stock and/or options, warrants or other Common Stock purchase rights and the Common Stock issued pursuant
to such options, warrants or other rights to employees, officers or directors of, or consultants or advisors to, the Company
or any subsidiary pursuant to stock purchase or stock option plans or other arrangements, the principal purpose of which is
other than the raising of capital through the sale of equity securities of the Company and the terms of which are approved by
the Board of Directors;

 

    15

     

    

 

(v)               
the issuance of shares of Common Stock or Convertible Securities to financial institutions, equipment lessors, landlords,
brokers or similar entities in connection with commercial credit arrangements, equipment financings, commercial property lease
transactions or similar transactions, the principal purpose of which is other than the raising of capital through the sale of equity
securities of the Company and the terms of which are approved by the Board of Directors;

 

(vi)             
the issuance of shares of Common Stock or Convertible Securities in connection with bona fide acquisitions, mergers
or similar transactions, the terms of which are approved by the Board of Directors;

 

(vii)           
shares of Common Stock issued or issuable upon the conversion of the Preferred Stock or the exercise of the Common Warrants;

 

(viii)         
shares of Common Stock issued or issuable pursuant to a Qualified Public Offering; or

 

(ix)             
shares of Common Stock or Convertible Securities issuable or issued to an entity as a component of any corporate strategic
relationship or transaction, the principal purpose of which is other than the raising of capital through the sale of equity securities
of the Company and which terms are approved by the Board of Directors.

 

(e)            
Notwithstanding the foregoing, the right of first offer in this Section 3.4 shall not be applicable to any Major Investor
with respect to any issuance of Shares if (i) at the time the Company issues such Shares, such Major Investor is not an “accredited
investor,” as defined in Rule 501(d) of Regulation D promulgated under the Securities Act, and (ii) such issuance of Shares
is only being offered by the Company to accredited investors.

 

3.5           Liability Insurance. The Company shall, at all times, maintain a directors’ and officers’ liability insurance
policy from a financially sound and reputable insurer with coverage limits reasonably acceptable to the majority of directors appointed
by the holders of Preferred Stock serving on the Board of Directors.

 

3.6           Stock
Vesting. Unless otherwise approved by the Board of Directors, all stock, stock options and other stock equivalents issued
after the date of this Agreement to employees, directors, consultants and other service providers shall be subject to vesting
as follows: (a) twenty-five percent (25%) of such stock shall vest at the end of the first year following the earlier of the date
of issuance or such person’s services commencement date with the Company, and (b) seventy-five percent (75%) of such stock
shall vest in equal monthly installments over the remaining three (3) years. With respect to any shares of stock purchased by
any such person still subject to vesting, the Company’s repurchase option shall provide that upon such person’s termination
of employment or service with the Company, with or without cause, the Company or its assignee shall have the option to purchase
at cost any unvested shares of stock held by such person. No stock option, restricted stock or similar equity grant to officers,
employees and consultants shall be transferable until such time as such stock option, restricted stock or similar equity grant
is fully vested.

 

3.7           Confidentiality
and Inventions Assignment Agreement. The Company shall require all employees to execute and deliver a Confidentiality and
Inventions Assignment Agreement substantially in a form approved by the Company’s counsel or Board of Directors and all
consultants to execute and deliver a consulting agreement containing reasonable provisions regarding the protection of the Company’s
confidential information and assignment of intellectual property created on behalf of the Company.

 

    16

     

    

 

3.8           Right of First Refusal. All shares of Common Stock of the Company shall be subject to a right of first refusal on all
transfers, which right shall be subject to the exemptions set forth in Article X, Sections 1(e) and 1(f) of the Company’s
Amended and Restated Bylaws. In the event the Company elects not to exercise any right of first refusal or right of first offer
the Company may have on a proposed transfer of any of the Company’s outstanding capital stock pursuant to the Company’s
charter documents, by contract or otherwise, the Company shall, to the extent it may do so, assign such right of first refusal
or right of first offer to each Major Investor. In the event of such assignment, each Major Investor shall have a right to purchase
its pro rata portion of the capital stock proposed to be transferred. Each Major Investor’s pro rata portion
shall be equal to the product obtained by multiplying (i) the aggregate number of shares proposed to be transferred by (ii) a fraction,
the numerator of which is the number of shares of Registrable Securities held by such Major Investor at the time of the proposed
transfer and the denominator of which is the total number of Registrable Securities owned by all Major Investors at the time of
such proposed transfer. If any Major Investors do not exercise in full this right of first refusal, the shares that would otherwise
be allocated to such non-fully exercising Major Investors shall be allocated among the fully exercising Major Investors wishing
to purchase the remaining shares (the “Over-Allotment”) on a pro-rata basis (calculated in the
same manner as above, provided, however, the denominator for purposes of such calculation shall be the total number of shares
held by all Major Investors participating in such Over-Allotment) up to the maximum shares specified by each such applicable Major
Investor. The Major Investors shall be entitled to apportion shares of Company capital stock purchasable hereunder among their
respective partners and affiliates in such proportions as they deem appropriate; provided, that any such partner or affiliate
shall, if not already a party, agree to become a party to this Agreement as an “Investor” hereunder.

 

3.9           Market Stand-off Restrictions. All capital stock issued by the Company, including any capital stock issuable or issued
upon exercise or conversion of any “Convertible Securities,” as defined in the Restated Certificate, shall be subject
to a market stand-off provision substantially similar to Section 2 of this Agreement.

 

3.10         Expenses Relating to Board Meetings. The Company shall promptly reimburse in full, each non-employee director of the
Company for all of his or her reasonable out-of-pocket expenses incurred related to attending meetings of the Company’s Board
of Directors or any committee thereof.

 

3.11         Board Approval. The Company hereby covenants and agrees with each of the Investors that it shall not, without approval
of the Board of Directors, which approval must include the affirmative vote of at least one of the directors appointed by the holders
of Preferred Stock:

 

(a)               
make, or permit any subsidiary to make, any loan or advance to, or own any stock or other securities of, any subsidiary
or other corporation, partnership, or other entity unless it is majority owned by the Company;

 

(b)              
make, or permit any subsidiary to make, any loan or advance to any person, including, without limitation, any employee
or director of the Company or any subsidiary, except advances and similar expenditures in the ordinary course of business or under
the terms of an employee stock or option plan approved by the Board of Directors;

 

    17

     

    

 

(c)               
 guarantee, directly or indirectly, or permit any subsidiary to guarantee, directly or indirectly, any indebtedness
except for trade accounts of the Company or any subsidiary arising in the ordinary course of business;

 

(d)              
incur any aggregate indebtedness in excess of $20,000 that is not already included in a budget approved by the Board
of Directors, other than trade credit or indebtedness to the Company incurred in the ordinary course of business;

 

(e)               
otherwise enter into or be a party to any transaction with any director, officer, or employee of the Company or any
 “associate” (as defined in Rule 12b-2 promulgated under the Exchange Act) of any such person, except for transactions
contemplated by this Agreement or the Financing, or transactions made in the ordinary course of business and pursuant to reasonable
requirements of the Company’s business and upon fair and reasonable terms that are approved by a majority of the Board of
Directors;

 

(f)                
hire, terminate, or change the compensation of the Chief Executive Officer;

 

(g)               
sell, assign, license, pledge, or encumber material technology or intellectual property, other than licenses granted
in the ordinary course of business;

 

(h)              
enter into any corporate strategic relationship involving the payment, contribution, or assignment by the Company or
to the Company of money or assets greater than $250,000; or

 

(i)                
enter into or joinder as a party to any transaction with any director or officer of the Company (other than for the
payment of salary and reimbursement of expenses made in the ordinary course of business), unless approved by a majority of the
directors who are disinterested in such transaction (with any interested director being required to recuse himself or herself).

 

3.12        Successor
Indemnification. If the Company or any of its successors or assignees consolidates with or merges into any other person and
is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper
provision shall be made so that the successors and assignees of the Company assume the obligations of the Company with respect
to indemnification of members of the Board of Directors as in effect immediately before such transaction, whether such obligations
are contained in the Company’s Amended and Restated Bylaws, its Restated Certificate, or elsewhere, as the case may be.

 

3.13        Investor
Form S-3 Registration Agreement. Following the closing of a Qualified IPO (as defined in the Restated Certificate), upon or
after the expiration of the Lockup Period, if the Company shall receive a written request from any Investor who may be deemed
an “affiliate” (as defined for this purpose in Rule 144), the Company agrees to enter into a Registration Rights Agreement,
in substantially the form attached hereto as Exhibit B, with such Investor. In the event any Registration Rights Agreement
is entered into, and any demand for registration is made pursuant thereto, it will be deemed to be a demand for registration pursuant
to the relevant section(s) of this Agreement for so long as such rights exist pursuant to this Agreement.

 

3.14        Termination
of Covenants. Except as set forth below, the covenants set forth in this Section 3 (other than Section 3.12) shall
terminate and be of no further force or effect upon the earlier of (a) the closing of a Qualified IPO; or (b) the
effective date of a Change of Control pursuant to which the Holders receive cash or securities traded on a nationally
recognized securities exchange. The covenants set forth in Sections 3.1 and 3.2 shall also terminate and be of no further
force or effect upon the Company becoming subject to the reporting provisions of the Exchange Act. Section
3.13 of this Agreement shall only terminate upon such time that such Investor, as reflected on the Company’s list of
stockholders, holds less than 1% of the Company’s outstanding Common Stock (treating all shares of Preferred Stock on
an as-converted basis), the Company has completed its IPO and all Registrable Securities of the Company issuable or issued
upon conversion of the Shares held by and issuable to such Investor may be sold pursuant to Rule 144 during any ninety (90)
day period.

 

    18

     

    

 

4.             Additional Covenants of the Parties.

 

4.1                FIRPTA. For so long as New Enterprise Associates 13, Limited Partnership; NEA Ventures 2009, Limited Partnership; KPCB
Holdings, Inc.; the Column Group, LP; ABG II-3V Limited; Rock Springs Capital Master Fund LP; Four Pines Master Fund LP; Baker
Brothers Life Sciences, L.P. and 667, L.P. (“Baker Brothers,” and each, individually, a “Participant”)
holds Preferred Stock of the Company or Registrable Securities, the Company shall provide prompt notice to the Participant, following
any “determination date” (as defined in United States Treasury Regulation Section 1.897-2(c)(1)) on which the
Company becomes a United States real property holding corporation. In addition, upon a written request by a Participant, the Company
shall provide the Participant with a written statement informing the Participant whether such Participant’s interest in the
Company constitutes a United States real property interest. The Company’s determination shall comply with the requirements
of Treasury Regulation Section 1.897-2(h)(1) or any successor regulation, and the Company shall provide timely notice to the
Internal Revenue Service, in accordance with and to the extent required by Treasury Regulation Section 1.897-2(h)(2) or any
successor regulation, that such statement has been made. The Company’s written statement to the Participant shall be delivered
to the Participant within 10 days of the Participant’s written request therefor. The Company’s obligation to furnish
such written statement shall continue notwithstanding the fact that a class of the Company’s stock may be regularly traded
on an established securities market or the fact that there is no preferred stock then outstanding.

 

4.2                Commerce
Department Compliance. The Company may be required to file reports with the Bureau of Economic Analysis (the “BEA”)
of the US Commerce Department when a US affiliate of a foreign Investor if such foreign Investor, together with its affiliates,
directly or indirectly controls ten percent (10%) or more of the voting securities of the Company. Such foreign Investor that
is a foreign individual or entity or a US subsidiary or affiliate of a foreign parent covenants to provide information necessary
for the Company to comply with BEA filings required under the International Investment and Trade in Services Act.

 

4.3                Indemnification Agreement. Immediately prior to the election or appointment of the Baker Brothers Director (as defined
in the Voting Agreement) to the Board of Directors, the Company shall enter into an Indemnification Agreement with the Baker Brothers
Director, in form reasonably approved by Baker Brothers.

 

4.4               Right
to Conduct Activities. The Company hereby agrees and acknowledges that SGMT Holdings Limited, Rock Springs Capital Master
Fund LP, Four Pines Master Fund LP, PFM Healthcare Master Fund, L.P. and Invus Public Equity, L.P. are professional
investment organizations, and as such reviews the business plans and related proprietary information of many enterprises,
some of which may compete directly or indirectly with the Company’s business (as currently conducted or as currently
propose to be conducted). The Company hereby agrees that, to the extent permitted under applicable law, SGMT Holdings
Limited, Rock Springs Capital Master Fund LP, Four Pines Master Fund LP, PFM Healthcare Master Fund, L.P. and Invus Public
Equity, L.P. shall not be liable to the Company for any claim arising out of, or based upon, (i) the investment by SGMT
Holdings Limited, Rock Springs Capital Master Fund LP, Four Pines Master Fund LP, PFM Healthcare Master Fund, L.P. and Invus
Public Equity, L.P. in any entity competitive with the Company, or (ii) actions taken by any partner, officer, employee or
other representative of SGMT Holdings Limited, Rock Springs Capital Master Fund LP, Four Pines Master Fund LP, PFM Healthcare
Master Fund, L.P. and Invus Public Equity, L.P. to assist any such competitive company, whether or not such action was taken
as a member of the board of directors of such competitive company or otherwise, and whether or not such action has a
detrimental effect on the Company; provided, however, that the foregoing shall not relieve (x) any of the
Investors from liability associated with the unauthorized disclosure of the Company’s confidential information obtained
pursuant to this Agreement, or (y) any director or officer of the Company from any liability associated with his or her
fiduciary duties to the Company.

 

    19

     

    

 

4.5               Qualified Small Business Stock. The Company agrees that for so long as any shares of Preferred Stock are held by an
Investor (or transferee) in whose hands such shares are eligible to qualify as “qualified small business stock” within
the meaning of Section 1202(c) of the Internal Revenue Code (the “Code”) it will (a) use best commercial
efforts to comply with any applicable filing and reporting requirements of Section 1202 of the Code and any regulations promulgated
thereunder; provided, however, that “best commercial efforts” as used in this section shall not be construed
to require the Company to operate its business in a manner which would adversely affect its business, limit its future prospects
or alter the timing or resource allocation of its planned operations or financing activities and (b) provide appropriate documentation
as to status with respect to “qualified small business stock” to each Investor that makes a request therefor within
ten (10) days of any such request.

 

5.             Miscellaneous.

 

5.1               Successors
and Assigns. Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of
and be binding upon the respective successors and assigns of the parties (including transferees of any shares of Registrable Securities).
Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective
successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly
provided in this Agreement.

 

5.2               Governing
Law. This Agreement shall be governed by the internal law of the State of Delaware, without regard to conflict of law principles
that would result in the application of any law other than the law of the State of Delaware.

 

5.3               Venue.
 Any suit or proceeding relating to, arising out of or arising under this Agreement shall be brought in the Delaware Court
of Chancery, which court shall have the sole and exclusive in personal, subject matter and other jurisdiction in connection with
such suit or proceedings and venue shall be appropriate for all purposes in such court.

 

5.4               Counterparts.
This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. Counterparts may be delivered via electronic mail (including pdf or any
electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and
any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

 

5.5               Titles
and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered
in construing or interpreting this Agreement.

 

5.6               Notices.
All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery
to the party to be notified; (b) when sent by confirmed electronic mail if sent during normal business hours of the recipient,
if not, then on the next business day; (c) five business days after having been sent by registered or certified mail, return receipt
requested, postage prepaid; or (d) one business day after deposit with a nationally recognized overnight courier, specifying next

5.7               Amendments
and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company,
the Holders of a majority of the Registrable Securities then outstanding (assuming conversion of all Preferred Stock and exercise
of the Common Warrants) and the approval of a majority of the Board of Directors; provided, that the Schedule of Investors
attached as Exhibit A hereto may be amended by the Company without the consent of the Holders to include any additional
Holders of additional shares of Series F Preferred Stock sold and issued by the Company in any Additional Closing, as defined
in the Purchase Agreement; provided further, that any other section of this Agreement applicable to the Major Investors
may be amended, modified, terminated or waived only with the written consent of the Company and the holders of a majority of the
Registrable Securities then outstanding and held by the Major Investors; and provided further, that the consent of Baker
Brothers, SGMT Holdings Limited, Invus Public Equity, L.P., PFM Healthcare Master Fund, L.P., New Enterprise Associates 13, Limited
Partnership, KPCB Holdings, Inc., AP 11 Limited, Qianhai Ark (Cayman) Investment Co. Limited, Rock Springs Capital Master Fund
LP and Four Pines Master Fund LP shall be required to amend, modify, terminate or waive Section 3.1 in a manner that affects such
Investor, including, for the avoidance of doubt, the minimum number of shares necessary to be deemed a “Major Investor”
thereunder. Sections 3.13 and the last sentence of Section 3.14 may be amended, modified, terminated or waived only with the written
consent of the Company and Baker Brothers. Further, this Agreement may not be amended, and no provision hereof may be waived,
in each case, in any way that by its terms treats (a) a particular Investor in a disproportionately adverse manner relative to
the other Investors without such Investor’s written consent, or (b) a particular Major Investor in a disproportionately
adverse manner relative to the other Major Investors without such Major Investor’s written consent it being understood in
each instance that an Investor or Major Investor, as applicable, shall not be deemed to be treated differently because of the
proportional differences in the amounts of respective issue prices, liquidation preferences and redemption prices that arise out
of differences in the original issue price vis-à-vis other existing or future series of Preferred Stock. Notwithstanding
the foregoing, the Major Investors agree that a waiver of the provisions of Section 3.4 with respect to a particular transaction
shall be deemed to apply to all Major Investors in the same fashion if such waiver does so by its terms, notwithstanding the fact
that certain Major Investors may nonetheless, by agreement with the Company, purchase securities in such transaction, provided,
a Major Investor shall have the right to purchase its pro rata number of securities in such transaction, regardless of the waiver
of the provisions of Section 3.4, if any other Major Investor purchases in the same transaction. The Company will give reasonably
prompt notice of any amendment or termination hereof or waiver hereunder (other than a waiver by an Investor of only such Investor’s
rights hereunder) to any party hereto that did not consent in writing to such amendment, termination or waiver. Any amendment
effected in accordance with this Section 5.7 shall be binding upon each Holder of Registrable Securities of the Company.

 

    21

     

    

 

5.8               Severability.
If any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect, such provision will be
enforced to the maximum extent possible and such invalidity, illegality or unenforceability will not affect any other provision
of this Agreement. In such event, the parties shall negotiate, in good faith, a legal, valid and enforceable substitute provision
which most nearly effects the intent of the parties in entering into this Agreement.

 

5.9               Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party to this Agreement,
upon any breach or default of any party to this Agreement, shall impair any such right, power or remedy of such non-breaching or
non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, of or
in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver
of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character
on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions
or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.
All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

 

5.10              Entire Agreement. This Agreement constitutes the entire agreement between the parties hereto pertaining to the subject
matter hereof, and any and all other written or oral agreements relating to the subject matter hereof existing between the parties
hereto are expressly canceled.

 

5.11              Aggregation
of Stock.  All shares of Registrable Securities of the Company held or acquired by a stockholder and its affiliated entities
shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

 

5.12              Advice
of Counsel. EACH PARTY TO THIS AGREEMENT ACKNOWLEDGES THAT, IN EXECUTING THIS AGREEMENT, SUCH PARTY HAS HAD THE OPPORTUNITY
TO SEEK THE ADVICE OF INDEPENDENT LEGAL COUNSEL, AND HAS READ AND UNDERSTOOD ALL OF THE TERMS AND PROVISIONS OF THIS AGREEMENT.
THIS AGREEMENT SHALL NOT BE CONSTRUED AGAINST ANY PARTY BY REASON OF THE DRAFTING OR PREPARATION HEREOF.
