 ATTACHMENT I 

FORTY SEVEN, INC. 

2018 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 

(INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK
OPTION) 
 Pursuant to your Stock Option Grant Notice (“Stock Option Grant Notice”) and this
Option Agreement (this “Agreement”), Forty Seven, Inc. (the “Company”) has granted you an option under its 2018 Equity Incentive Plan (the “Plan”) to purchase the number of
shares of the Company’s Common Stock indicated in your Stock Option Grant Notice at the exercise price indicated in your Stock Option Grant Notice. The option is granted to you effective as of the date of grant set forth in the Stock Option
Grant Notice (the “Date of Grant”). If there is any conflict between the terms in this Agreement and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Agreement or in the Stock
Option Grant Notice but defined in the Plan will have the same definitions as in the Plan. 
 The details of your option, in addition to
those set forth in the Stock Option Grant Notice and the Plan, are as follows: 
 1. VESTING.
Your option will vest as provided in your Stock Option Grant Notice. Vesting will cease upon the termination of your Continuous Service, as described in Section 8 below. 

2. NUMBER OF SHARES AND EXERCISE
PRICE. The number of shares of Common Stock subject to your option and your exercise price per share in your Stock Option Grant Notice will be adjusted for Capitalization Adjustments. 

3. EXERCISE RESTRICTION FOR NON-EXEMPT
EMPLOYEES. If you are an Employee eligible for overtime compensation under the U.S. Fair Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”), and except as
otherwise provided in the Plan, you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant, even if you have already been an employee for more than six
(6) months. Consistent with the provisions of the U.S. Worker Economic Opportunity Act, you may exercise your option as to any vested portion prior to such six (6) month anniversary in the case of (i) your death or disability,
(ii) a Corporate Transaction in which your option is not assumed, continued or substituted, (iii) a Change in Control or (iv) your termination of Continuous Service on your “retirement” (as defined in the Company’s
benefit plans). 
 4. INCENTIVE STOCK OPTION
LIMITATION. If your option is an Incentive Stock Option, then, to the extent that the aggregate Fair Market Value (determined at the Date 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) will be treated as Nonstatutory Stock Options. 
 5.
METHOD OF PAYMENT. You must pay the full amount of the exercise price for the shares you wish to exercise. You may pay the exercise price in cash or by check, bank draft, wire
transfer or money order payable to the Company or in any other manner permitted by your Stock Option 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, 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. This manner of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover,” 

(b) Provided that at the time of exercise the Common Stock is publicly traded, 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 whose Fair Market Value is equal to the aggregate exercise price on the date of exercise.
“Delivery” for these purposes, in the sole discretion of the Company at the time you exercise your option, will include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the
Company. You may not exercise your option by delivery to the Company of Common Stock if doing so 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. COMPLIANCE. In no event may you exercise your option unless the shares of Common Stock
issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of the shares would be exempt from the registration requirements of the Securities Act. The
exercise of your option also must comply with all other applicable laws and regulations governing your option, including any U.S. state, federal and local laws, 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 (including any restrictions on exercise required for compliance with Treas. Reg. 1.401(k)-1(d)(3), if applicable). 

8. TERM. You may not exercise your option before the Date of Grant or after the expiration of the
option’s term. The term of your option expires, subject to the provisions of Section 5(h) of the Plan, upon the earliest of the following: 

(a) immediately upon the termination of your Continuous Service for Cause; 

(b) three (3) months after the termination of your Continuous Service for any reason other than Cause, your Disability, or your
death (except as otherwise provided in Section 8(d) below); provided, however, that if during any part of such three-month period your option is not exercisable solely because of the condition set forth in the section above
relating to “Compliance,” your option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; provided
further, that if (i) you are a Non-Exempt Employee, (ii) your Continuous Service terminates within six (6) months after the Date of Grant, and (iii) you have vested in a portion of your option at the time of your termination
of Continuous Service, your option will not expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date of Grant, and (B) the date that is three (3) months after the termination of your
Continuous Service, and (y) the Expiration Date; 
 (c) twelve (12) months after the termination of your Continuous Service
due to your Disability (except as otherwise provided in Section 8(d) below); 

  
 2 









 (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; 
 (e) the
Expiration Date indicated in your Stock Option Grant Notice; and 
 (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 U.S. federal income tax advantages associated with an
Incentive Stock Option, the Code requires that at all times beginning on the Date of Grant 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. 
 For purposes of your option, your Continuous Service will be considered terminated (regardless of the reason of
termination, whether or not later found to be invalid or in breach of employment or other laws or rules in the jurisdiction where you are providing services or the terms of your employment or service agreement, if any) effective as of the date that
you cease to actively provide services to the Company or any Affiliate and will not be extended by any notice period (e.g., employment or service would not include any contractual notice period or any period of “garden leave” or
similar period mandated under employment or other laws in the jurisdiction where you are employed or providing services or the terms of your employment or service agreement, if any). The Board shall have exclusive discretion to determine when you
are no longer actively employed or providing services for purposes of the Plan (including whether you still may be considered to be providing services while on a leave of absence). 

9. EXERCISE. 

(a) You may exercise the vested portion of your option during its term by (i) delivering a Notice of Exercise (in a form designated
by the Company) or completing such other documents and/or procedures designated by the Company for exercise and (ii) paying the exercise price and any applicable Tax-Related Items (as defined in Section 11 below) to the Company’s
Secretary, stock plan administrator, or such other person as the Company may designate, 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-Related Items. 
 (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 Grant or within one (1) year after such shares of Common Stock are transferred upon exercise of your option. 

(d) By exercising your option you agree that you 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 

  
 3 









 
transaction with the same economic effect as a sale with respect to 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 (the “Lock-Up Period”); provided, however, that nothing contained in this section will 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 or the underwriters 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. You also agree
that any transferee of any shares of Common Stock (or other securities) of the Company held by you will be bound by this Section 9(d). The underwriters of the Company’s stock are intended third party beneficiaries of this Section 9(d)
and will have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 
 10.
TRANSFERABILITY. Except as otherwise provided in this Section 10, 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. 
 (a) Certain Trusts. Upon receiving written permission from the Board or its duly authorized designee, 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 U.S. state law) while the option is held in the trust. You and the trustee must enter into transfer and other
agreements required by the Company. 
 (b) Domestic Relations Orders. Upon receiving written permission from the Board or its
duly authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your option pursuant to the terms of a domestic relations order, official marital
settlement agreement or other divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of
any division of this option with the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required information is contained within the domestic relations order or marital settlement agreement.
If this option is an Incentive Stock Option, this option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 

(c) Beneficiary Designation. Upon receiving written permission from the Board or its duly authorized designee, you may, by
delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to handle option exercises, designate a third party who, on your death, will thereafter be entitled to exercise this option and
receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, your executor or administrator of your estate or your legal heirs will be entitled to exercise this option and receive, on behalf of
your estate, the Common Stock or other consideration resulting from such exercise. 
 11. RESPONSIBILITY FOR
TAXES. 
 (a) You acknowledge that, regardless of any action the Company or, if different, your
employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, fringe benefit tax, payment on account or other tax related items related to your participation in the Plan and legally
applicable to you (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains your responsibility and may exceed the amount actually withheld by the Company or the Employer, if any. You further
acknowledge that the Company and the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any 

  
 4 









 
aspect of your option, including, but not limited to, the grant, vesting or exercise of your option, the subsequent sale of shares of Common Stock acquired pursuant to such exercise and the
issuance of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of your option to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result.
You acknowledge and agree that you will not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates for Tax-Related Items arising from your option. 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. Further, if you are subject to Tax-Related Items in more than one jurisdiction, you acknowledge that the Company and/or the Employer may be required to withhold or account for Tax-Related Items in more
than one jurisdiction. 
 (b) Prior to the relevant taxable or tax withholding event, as applicable, you agree to make adequate
arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, you authorize the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations
with regard to all Tax-Related Items by: (i) withholding from your wages or other cash compensation paid to you by the Company and/or the Employer, (ii) withholding from the proceeds of the sale of shares of Common Stock acquired at
exercise of your option and sold either through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf pursuant to this authorization without further consent); and/or (iii) if this option is a Nonstatutory Stock
Option, withholding a number of shares of Common Stock that are otherwise deliverable to you upon exercise. 
 (c) Depending on the
withholding method, the Company or the Employer may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates, including maximum applicable rates, in which case
you may receive a refund of any over-withheld amount in cash and will have no entitlement to the Common Stock equivalent. If the obligation for Tax-Related Items is satisfied by withholding a number of shares of Common Stock, for tax purposes, you
are deemed to have been issued the full number of shares of Common Stock, notwithstanding that a number of the shares of Common Stock is held back solely for the purpose of paying the Tax-Related Items. 

(d) You agree to pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to
withhold or account for as a result of your participation in the Plan that cannot be satisfied by the means previously described. You acknowledge and agree that the Company may refuse to honor the exercise and refuse to issue or deliver the shares
of Common Stock, or the proceeds of the sale of the shares of Common Stock, if you fail to comply with your obligations in connection with the Tax-Related Items. 

12. NATURE OF GRANT. In accepting your option, you acknowledge, understand
and agree that: 
 (a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified,
amended, suspended or terminated by the Company at any time, to the extent permitted under the Plan; 
 (b) the grant of this option
is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of options (whether on the same or different terms), or benefits in lieu of options, even if options have been granted in the past;


  
 5 









 (c) all decisions with respect to future options or other grants, if any, will be at the
sole discretion of the Company; 
 (d) you are voluntarily participating in the Plan; 

(e) this option and the shares of Common Stock subject to this option, and the income and value of same, are not intended to replace any
pension rights or compensation; 
 (f) the future value of the shares of Common Stock underlying the option is unknown,
indeterminable, and cannot be predicted with certainty; 
 (g) if the underlying shares of Common Stock do not increase in value, the
option will have no value; 
 (h) if you exercise the option and acquire shares of Common Stock, the value of such shares of Common
Stock may increase or decrease in value, even below the exercise price 
 (i) no claim or entitlement to compensation or damages shall
arise from forfeiture of this option resulting from the termination of your Continuous Service (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or
rendering services or the terms of your employment or service agreement, if any), and in consideration of the grant of this option, you irrevocably agree not to institute any claim against the Company or any Affiliate, 

(j) unless otherwise provided in the Plan or by the Company in its discretion, the option and the benefits evidenced by this Agreement
do not create any entitlement to have the option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the shares of Common
Stock; and 
 (k) unless otherwise agreed with the Company, this option and any shares of Common Stock acquired under the Plan, and
the income and value of same, are not granted as consideration for, or in connection with, the service you may provide as a director of an Affiliate. 

13. NO ADVICE REGARDING GRANT. The Company is not providing
any tax, legal or financial advice, nor is the Company making any recommendations regarding your participation in the Plan, or your acquisition or sale of the underlying shares of Common Stock. You are hereby advised to consult with your own
personal tax, legal and financial advisors regarding your participation in the Plan before taking any action related to the Plan. 
 14.
RIGHT OF REPURCHASE. The Company will have the right to repurchase all of the shares of Common Stock you acquire pursuant to the exercise of your option upon termination of your
Continuous Service for Cause. Such repurchase will be at the exercise price you paid to acquire the shares and will be effected pursuant to such other terms and conditions, and at such time, as the Company will determine. 

15. OPTION NOT A SERVICE CONTRACT. Your
option is not an employment or service contract, and nothing in your option will be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Employer, or of the Employer to continue your employment. In
addition, nothing in your option will obligate the Company or an Affiliate, their respective stockholders, boards of directors, officers or employees to continue any relationship that you might have 


  
 6 









 
as a Director or Consultant for the Company or an Affiliate. Finally, the grant of the option shall not be interpreted as forming an employment or service contract with the Company. 

16. NOTICES. Any notices provided for in your option or the Plan will be given in writing
(including electronically) and will 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. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this option by electronic means or to request your consent to participate in the Plan by
electronic means. By accepting this option, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by
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.
If there is any conflict between the provisions of your option and those of the Plan, the provisions of the Plan will control. In addition, your option (and any compensation paid or shares issued under your option) is subject to recoupment in
accordance with The U.S. Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable
law. No recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntarily terminate employment upon a resignation for “good reason,” or for a “constructive termination” or any similar
term under any plan of or agreement with the Company. 
 18. OTHER DOCUMENTS. You hereby
acknowledge receipt of and the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus. In addition, you acknowledge receipt of the Company’s
policy permitting certain individuals to sell shares only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

19. VOTING RIGHTS. You will not have voting or any other rights as a shareholder of the
Company with respect to the shares to be issued pursuant to this option until such shares are issued to you. Upon such issuance, you will obtain full voting and other rights as a shareholder of the Company. Nothing contained in this option, and no
action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

20. SEVERABILITY. If all or any part of this Agreement or the Plan is declared by any court or
governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so
declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

21. INSIDER TRADING RESTRICTIONS/MARKET ABUSE
LAWS. You acknowledge that you may be subject to insider trading restrictions and/or market abuse laws, which may affect your ability to acquire or sell the shares of Common Stock or rights to the shares of
Common Stock under the Plan during such times as you are considered to have “inside information” regarding the Company (as defined by the laws). Any restrictions under these laws or regulations are separate from and in addition to any
restrictions that may be imposed under any applicable Company insider trading policy. You acknowledge 

  
 7 









 
that it is your responsibility to comply with any applicable restrictions, and you are advised to speak to your personal advisor on this matter. 

22. IMPOSITION OF OTHER REQUIREMENTS. The Company reserves
the right to impose other requirements on your participation in the Plan, and on any shares of Common Stock acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to
require you to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing. 
 23.
GOVERNING LAW/VENUE. The interpretation, performance and enforcement of this Agreement will be governed by the law of the State of Delaware without regard to that state’s
conflicts of laws rules. For purposes of any action, lawsuit or other proceedings brought to enforce this Agreement, including its Exhibit, relating to it, or arising from it, the parties hereby submit to and consent to the sole and exclusive
jurisdiction of the courts within Santa Clara County, State of California, and no other courts, where this grant is made and/or to be performed. 

24. MISCELLANEOUS. 

(a) The rights and obligations of the Company under your option will be transferable to any one or more persons or entities, and all
covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns. 
 (b)
You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the Company to carry out the purposes or intent of your option. 

(c) You acknowledge and agree that you have reviewed your option in its entirety, have had an opportunity to obtain the advice of
counsel prior to executing and accepting your option, and fully understand all provisions of your option. 
 (d) All obligations of
the Company under the Plan and this Agreement will be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all
of the business and/or assets of the Company. 

*                *       
         * 
 This Agreement will be deemed to be signed by you upon the signing by you or 

otherwise by your acceptance of the Grant Notice to which it is attached.

Act”), and are deemed to constitute “restricted securities” under Rule 701 and 
  

	1 	Shares must meet the public trading requirements set forth in the option agreement. 


	2 	Shares must meet the public trading requirements set forth in the option agreement. Shares must be valued in accordance with the terms of the option being exercised, and must be owned free and clear of any liens,
claims, encumbrances or security interests. Certificates must be endorsed or accompanied by an executed assignment separate from certificate. 









 
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 (90) days 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 will 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 acknowledge and agree that, except for such information as required to be delivered to me by the Company
pursuant to the option or the Plan (if any), I will have no right to receive any information from the Company by virtue of the grant of the option or the purchase of shares of Common Stock through exercise of the option, ownership of such shares of
Common Stock, or as a result of my being a holder of record of stock of the Company. Without limiting the foregoing, to the fullest extent permitted by law, I hereby waive all inspection rights under Section 220 of the Delaware General
Corporation Law and all such similar information and/or inspection rights that may be provided under the law of any jurisdiction, or any federal, state or foreign regulation, that are, or may become, applicable to the Company or the Company’s
capital stock (the “Inspection Rights”). I hereby covenant and agree never to directly or indirectly commence, voluntarily aid in any way, prosecute, assign, transfer, or cause to be commenced any claim, action, cause of
action, or other proceeding to pursue or exercise the Inspection Rights. 
 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 with respect to any shares of Common Stock or other securities of the Company 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 the underwriters or the Company will request to facilitate compliance with FINRA Rule 2241 or any successor or similar rule or
regulation) (the “Lock-Up Period”). I further agree to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriters 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 securities subject to the foregoing restrictions until the end of
such period.
