OPTION AGREEMENT

 ARIOSA DIAGNOSTICS, INC. 

2009 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 

(INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK
OPTION) 
 Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement,
ARIOSA DIAGNOSTICS, INC. (the “Company”) has granted you an option under its 2009 Equity Incentive Plan (the “Plan”) to purchase the number of shares
of the Company’s Common Stock indicated in your Grant Notice at the exercise price indicated in your Grant Notice. Defined terms not explicitly defined in this Option Agreement but defined in the Plan shall have the same definitions as in the
Plan. 
 The details of your option are as follows: 

1. VESTING. Subject to the limitations contained herein, your option will vest as provided
in your Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. 
 2. NUMBER
OF SHARES AND EXERCISE PRICE. The number of shares of Common Stock subject to your option and your exercise price per share referenced in your Grant Notice may be
adjusted from time to time for Capitalization Adjustments. 
 3. EXERCISE RESTRICTION FOR
NON-EXEMPT EMPLOYEES. In the event that you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (i.e., a “Non-Exempt
Employee”), you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant specified in your Grant Notice, notwithstanding any other provision of your option.

 4. EXERCISE PRIOR TO VESTING (“EARLY
EXERCISE”). If permitted in your Grant Notice (i.e., the “Exercise Schedule” indicates “Early Exercise Permitted”) and subject to the provisions of your option, you may elect at any time that is
both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the unvested portion of your option; provided, however, that: 

(a) a partial exercise of your option shall be deemed to cover first vested shares of Common Stock and then the earliest vesting
installment of unvested shares of Common Stock; 
 (b) any shares of Common Stock so purchased from installments that have not vested
as of the date of exercise shall be subject to the purchase option in favor of the Company as described in the Company’s form of Early Exercise Stock Purchase Agreement; 

(c) you shall enter into the Company’s form of Early Exercise Stock Purchase Agreement with a vesting schedule that will result in
the same vesting as if no early exercise had occurred; and 

  
 2 








 (d) if your option is an Incentive Stock Option, then, to the extent that the aggregate
Fair Market Value (determined at the time of grant) of the shares of Common Stock with respect to which your option plus all other Incentive Stock Options you hold are exercisable for the first time by you during any calendar year (under all plans
of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 

5. METHOD OF PAYMENT. Payment of the exercise price is due in full upon exercise of all or
any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner permitted by your Grant Notice, which may include one or more of the following: 

(a) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, pursuant
to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds. 
 (b) Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, by delivery to the Company (either by actual delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or
security interests, and that are valued at Fair Market Value on the date of exercise. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of
any law, regulation or agreement restricting the redemption of the Company’s stock. 
 6. WHOLE
SHARES. You may exercise your option only for whole shares of Common Stock. 
 7.
SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then
registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of
your option also must comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 

8. TERM. You may not exercise your option before the commencement or after the expiration of its term. The term
of your option commences on the Date of Grant and expires upon the earliest of the following: 
 (a) immediately upon the termination
of your Continuous Service for Cause (as defined in the Plan); 

  
 3 








 (b) three (3) months after the termination of your Continuous Service for any reason
other than Cause (as defined in the Plan), Disability or death, provided that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above relating to
“Securities Law Compliance,” your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service;

 (c) twelve (12) months after the termination of your Continuous Service due to your Disability; 

(d) eighteen (18) months after your death if you die either during your Continuous Service or within three (3) months after
your Continuous Service terminates for any reason other than Cause (as defined in the Plan); 
 (e) the Expiration Date indicated in
your Grant Notice; or 
 (f) the day before the tenth (10th) anniversary of the Date of Grant. 

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option,
the Code requires that at all times beginning on the date of grant of your option and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event
of your death or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you
continue to provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an
Affiliate terminates. 
 9. EXERCISE. 

(a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during
its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with
such additional documents as the Company may then require. 
 (b) By exercising your option you agree that, as a condition to any
exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option,
(2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. 

(c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within
fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one (1) year after such
shares of Common Stock are transferred upon exercise of your option. 

  
 4 








 (d) By exercising your option you agree that you shall not sell, dispose of, 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, any shares of Common Stock or other securities of the Company held by you, for a period of one
hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer period as necessary to permit compliance with NASD Rule 2711 or NYSE Member Rule 472 and similar
rules and regulations (the “Lock-Up Period”); provided, however, that nothing contained in this section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You further
agree to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to your shares of Common Stock until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 9(d) and
shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 
 10.
TRANSFERABILITY. Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. In addition, if permitted by the Company you may transfer your option to a trust
if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust, provided that you and the trustee enter into a transfer and other agreements
required by the Company. 
 11. RIGHT OF FIRST REFUSAL. Shares of Common
Stock that you acquire upon exercise of your option are subject to any right of first refusal that may be described in the Company’s Bylaws in effect at such time the Company elects to exercise its right; provided, however, that if your
option is an Incentive Stock Option and the right of first refusal described in the Company’s Bylaws in effect at the time the Company elects to exercise its right is more beneficial to you than the right of first refusal described in the
Company’s Bylaws on the Date of Grant, then the right of first refusal described in the Company’s Bylaws on the Date of Grant shall apply. The Company’s right of first refusal shall expire on the first date upon which any security of
the Company is listed (or approved for listing) upon notice of issuance on a national securities exchange or quotation system. 
 12.
RIGHT OF REPURCHASE. To the extent provided in the Company’s Bylaws in effect at such time the Company elects to exercise its right, the Company shall have the right to repurchase all or any part
of the shares of Common Stock you acquire pursuant to the exercise of your option. 
 13. OPTION NOT
A SERVICE CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the
employ of the Company or an Affiliate, or of the 

  
 5 








 
Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers
or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 
 14.
WITHHOLDING OBLIGATIONS. 
 (a) At the time you exercise your option, in whole or in part, or at
any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant
to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an
Affiliate, if any, which arise in connection with the exercise of your option. 
 (b) Upon your request and subject to approval by
the Company, in its sole discretion, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole
shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of
your option as a liability for financial accounting purposes). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence
shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise
deferred, to accelerate the determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common
Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

(c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.
Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any
escrow provided for herein unless such obligations are satisfied. 
 15. TAX CONSEQUENCES. You hereby
agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You shall not make any claim against the Company, or any of its Officers, Directors,
Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the Code only if the exercise price per share specified in
the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with the option. Because the Common Stock


  
 6 








 
is not traded on an established securities market, the Fair Market Value is determined by the Board, perhaps in consultation with an independent valuation firm retained by the Company. You
acknowledge that there is no guarantee that the Internal Revenue Service will agree with the valuation as determined by the Board, and you shall not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in
the event that the Internal Revenue Service asserts that the valuation determined by the Board is less than the “fair market value” as subsequently determined by the Internal Revenue Service. 

16. NOTICES. Any notices provided for in your option or the Plan shall be given in writing and shall be deemed
effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 

17. GOVERNING PLAN DOCUMENT. Your option is subject to all the provisions of the Plan, the
provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict
between the provisions of your option and those of the Plan, the provisions of the Plan shall control.

both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the unvested portion of your option; provided, however, that:

Fair Market Value (determined at the time of grant) of the shares of Common Stock with respect to which your option plus all other Incentive Stock Options you hold are exercisable for the first time by you during any calendar year (under all plans
of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 

22. METHOD OF PAYMENT. Payment of the exercise price is due in
full upon exercise of all or any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner permitted by your Grant Notice, which may include one or more of the following:

 (a) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street
Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable
instructions to pay the aggregate exercise price to the Company from the sales proceeds.

encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate
the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 
 23. WHOLE
SHARES. You may exercise your option only for whole shares of Common Stock. 
 24. SECURITIES
LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act
or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option also must comply with
other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 

25. TERM. You may not exercise your option before the commencement or after the expiration of its term. The term of your
option commences on the Date of Grant and expires upon the earliest of the following: 
 (a) immediately upon the termination of your
Continuous Service for Cause (as defined in the Plan); 

  
 9 








 (b) three (3) months after the termination of your Continuous Service for any reason
other than Cause (as defined in the Plan), Disability or death, provided that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above relating to
“Securities Law Compliance,” your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service;

 (c) twelve (12) months after the termination of your Continuous Service due to your Disability; 

(d) eighteen (18) months after your death if you die either during your Continuous Service or within three (3) months after
your Continuous Service terminates for any reason other than Cause (as defined in the Plan); 
 (e) the Expiration Date indicated in
your Grant Notice; or 
 (f) the day before the tenth (10th) anniversary of the Date of Grant. 

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option,
the Code requires that at all times beginning on the date of grant of your option and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event
of your death or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you
continue to provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an
Affiliate terminates. 
 26. EXERCISE. 

(a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during
its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with
such additional documents as the Company may then require. 
 (b) By exercising your option you agree that, as a condition to any
exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option,
(2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. 

(c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within
fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one (1) year after such
shares of Common Stock are transferred upon exercise of your option. 

  
 10 








 (d) By exercising your option you agree that you shall not sell, dispose of, 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, any shares of Common Stock or other securities of the Company held by you, for a period of one
hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer period as necessary to permit compliance with NASD Rule 2711 or NYSE Member Rule 472 and similar
rules and regulations (the “Lock-Up Period”); provided, however, that nothing contained in this section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You further
agree to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to your shares of Common Stock until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 9(d) and
shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 
 27.
TRANSFERABILITY. Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. In addition, if permitted by the Company you may transfer your option to a trust
if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust, provided that you and the trustee enter into a transfer and other agreements
required by the Company. 
 28. RIGHT OF FIRST REFUSAL. Shares of
Common Stock that you acquire upon exercise of your option are subject to any right of first refusal that may be described in the Company’s Bylaws in effect at such time the Company elects to exercise its right; provided, however, that
if your option is an Incentive Stock Option and the right of first refusal described in the Company’s Bylaws in effect at the time the Company elects to exercise its right is more beneficial to you than the right of first refusal described in
the Company’s Bylaws on the Date of Grant, then the right of first refusal described in the Company’s Bylaws on the Date of Grant shall apply. The Company’s right of first refusal shall expire on the first date upon which any security
of the Company is listed (or approved for listing) upon notice of issuance on a national securities exchange or quotation system. 
 29.
RIGHT OF REPURCHASE. To the extent provided in the Company’s Bylaws in effect at such time the Company elects to exercise its right, the Company shall have the right to repurchase all or any part
of the shares of Common Stock you acquire pursuant to the exercise of your option. 
 30. OPTION NOT
A SERVICE CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the
employ of the Company or an Affiliate, or of the 

  
 11 








 
Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers
or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 
 31.
WITHHOLDING OBLIGATIONS. 
 (a) At the time you exercise your option, in whole or in part, or at
any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant
to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an
Affiliate, if any, which arise in connection with the exercise of your option. 
 (b) Upon your request and subject to approval by
the Company, in its sole discretion, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole
shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of
your option as a liability for financial accounting purposes). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence
shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise
deferred, to accelerate the determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common
Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

(c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.
Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any
escrow provided for herein unless such obligations are satisfied. 
 32. TAX CONSEQUENCES. You hereby
agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You shall not make any claim against the Company, or any of its Officers, Directors,
Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the Code only if the exercise price per share specified in
the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with the option. Because the Common Stock

 I hereby make
the following certifications and representations with respect to the number of shares of Common Stock of the Company listed above (the “Shares”), which are being acquired by me for my own account upon exercise of the Option as set forth
above: 







 I acknowledge that the Shares have not been registered under the Securities Act of 1933, as
amended (the “Securities Act”), and are deemed to constitute “restricted securities” under Rule 701 and “control securities” under Rule 144 promulgated under the Securities Act. I warrant and represent to the Company
that I have no present intention of distributing or selling said Shares, except as permitted under the Securities Act and any applicable state securities laws. 

I further acknowledge that I will not be able to resell the Shares for at least ninety days (90) after the stock of the Company becomes
publicly traded (i.e., subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934) under Rule 701 and that more restrictive conditions apply to affiliates of the Company under Rule 144. 

I further acknowledge that all certificates representing any of the Shares subject to the provisions of the Option shall have endorsed thereon
appropriate legends reflecting the foregoing limitations, as well as any legends reflecting restrictions pursuant to the Company’s Articles of Incorporation, Bylaws and/or applicable securities laws. 

I further agree that, if required by the Company (or a representative of the underwriters) in connection with the first underwritten
registration of the offering of any securities of the Company under the Securities Act, I will not sell, dispose of, 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, any Shares or other securities of the Company held by me, for a period of time specified by the underwriter(s) (not to exceed one hundred eighty (180) days) following the effective date of the registration
statement of the Company filed under the Securities Act. I further agree to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are
necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to my Shares until the end of such period. 

 

			
	Very truly yours,
