 ATTACHMENT I 

ITERUM THERAPEUTICS LIMITED 

2015 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 

(INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK OPTION) 

Pursuant to your Stock Option Grant Notice (the “Grant Notice”) and this Option Agreement, Iterum Therapeutics Limited
(the “Company”) has granted you an Option under its 2015 Equity Incentive Plan (the “Plan”) to purchase the number of the Company’s Ordinary Shares indicated in your Grant Notice at the exercise
price indicated in your Grant Notice. The Option is granted to you effective as of the date of grant set forth in the Grant Notice (the “Date of Grant”). If there is any conflict between the terms in this Option Agreement and
the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option Agreement or in the 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 Grant Notice and the Plan, are as follows: 

1.    VESTING. Your Option will vest as provided in your Grant Notice. Vesting
will cease upon the termination of your Continuous Service. 
 2.    NUMBER OF
SHARES AND EXERCISE PRICE. The number of Ordinary Shares subject to your Option and the exercise price per share in your 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 months of Continuous Service measured from the Date of Grant,
even if you have already been an employee for more than six 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 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, or (iii) your termination of Continuous Service on your “retirement” (as defined in the Company’s
benefit plans). 
 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 will be deemed to cover first vested Ordinary Shares and then the
earliest vesting installment of unvested Ordinary Shares; 
 (b)    any Ordinary Shares so purchased from
installments that have not vested as of the date of exercise will 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 will 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 

(d)    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 Ordinary Shares 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 $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 or money order payable to the Company 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 Ordinary Shares are
publicly traded, pursuant to a program developed under Regulation T as promulgated by the U.S. Federal Reserve Board that, prior to the issuance of Ordinary Shares, 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 Ordinary Shares are publicly traded, by delivery to the Company
(either by actual delivery or attestation) of already-owned Ordinary Shares 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.
“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 Ordinary Shares in a form approved by the Company. You
may not exercise your Option by delivery to the Company of Ordinary Shares if doing so would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 

(c)    If this Option is a Nonstatutory Stock Option, subject to the consent of the Company at the time of
exercise, by a “net exercise” arrangement pursuant to which the Company will reduce the number of Ordinary Shares issued upon exercise of your Option by the largest whole number of shares with a Fair Market Value that does not exceed the
aggregate exercise price. You must pay any remaining balance of the aggregate exercise price not satisfied by the “net exercise” in cash or other permitted form of payment. Ordinary Shares will no longer be outstanding under your Option
and will not be exercisable thereafter if those shares (i) are used to pay the exercise price pursuant to the “net exercise,” (ii) are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax
withholding obligations. 
 6.    WHOLE SHARES. You may
exercise your Option only for whole Ordinary Shares. 
 7.    SECURITIES LAW
COMPLIANCE. In no event may you exercise your Option unless the Ordinary Shares 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, 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 U.S. 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)    90 days 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 90 day period your Option is not exercisable solely because of the condition set forth in the section above
relating to “Securities Law Compliance,” your Option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of 90 days 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 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 months after the Date of Grant, and (B) the date that is three months after the
termination of your Continuous Service, and (y) the Expiration Date; and provided further, if during any part of such ninety-day period, the sale of any Ordinary Shares received upon exercise of
your Option would violate the Company’s insider trading policy, then your Option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of 90 days after the termination of your
Continuous Service during which the sale of the Ordinary Shares received upon exercise of your Option would not be in violation of the Company’s insider trading policy; 

(c)    12 months after the termination of your Continuous Service due to your Disability (except as otherwise
provided in Section 8(d)) below; 
 (d)    18 months after your death if you die either during your
Continuous Service or within 90 days after your Continuous Service terminates for any reason other than Cause; 

(e)    the Expiration Date indicated in your Grant Notice; or 

(f)    the day before the 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 and ending on the day three 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 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 (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 withholding taxes to the Company’s 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 withholding obligation of the Company arising by reason of
(i) the exercise of your Option, (ii) the lapse of any substantial risk of forfeiture to which the Ordinary Shares are subject at the time of exercise, or (iii) the disposition of Ordinary Shares 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 15 days after the date of any disposition of any of the Ordinary Shares issued upon exercise of your Option that occurs within two years after the Date of Grant or within one year after such Ordinary Shares are transferred
upon exercise of your Option. 

(d)    LOCK-UP IN
CONNECTION WITH PUBLIC OFFERING. 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 transaction with the same economic effect as a sale with respect to any Ordinary Shares or other securities of the Company held by you, for a period of 180 days following the effective date of a registration statement of
the Company (filed in the United States under the Securities Act or similar regulations in such applicable jurisdiction) or such longer period as the underwriters or the Company will request to facilitate compliance with FINRA Rule 2711 or NYSE
Member Rule 472 or any successor or similar rules or regulations (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 Ordinary Shares until the end of such
period. You also agree that any transferee of any Ordinary Shares (or other securities) of the Company held by you will be bound by this Section. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 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 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 Ordinary Shares or other consideration resulting from such exercise. In the absence of such a designation, your executor or administrator of your estate will be entitled
to exercise this Option and receive, on behalf of your estate, the Ordinary Shares or other consideration resulting from such exercise. 

11.    RIGHT OF FIRST REFUSAL.
Ordinary Shares that you acquire upon exercise of your Option are subject to any right of first refusal that may be described in the Company’s Constitution in effect at such time the Company elects to exercise its right; provided,
however, that if there is no right of first refusal described in the Company’s Constitution at such time, the right of first refusal described below will apply. The Company’s right of first refusal will 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 (the “Listing Date”). 

(a)    Prior to the Listing Date, you may not validly Transfer (as defined below) any Ordinary Shares acquired upon
exercise of your Option, or any interest in such shares, unless such Transfer is made in compliance with the following provisions: 

(i)    Before there can be a valid Transfer of any Ordinary Shares or any interest therein, the record holder of
the Ordinary Shares to be transferred (the “Offered Shares”) will give written notice (by registered or certified mail) to the Company. Such notice will specify the identity of the proposed transferee, the cash price offered
for the Offered Shares by the proposed transferee (or, if the proposed Transfer is one in which the holder will not receive cash, such as an involuntary transfer, gift, donation or pledge, the holder will state that no purchase price is being
proposed), and the other terms and conditions of the proposed Transfer. The date such notice is mailed will be hereinafter referred to as the “Notice Date” and the record holder of the Offered Shares will be hereinafter
referred to as the “Offeror.” If, from time to time, there is any stock dividend, stock split or other change in the character or amount of any of the outstanding Ordinary Shares which is subject to the provisions of your
Option, then in such event any and all new, substituted or additional securities to which you are entitled by reason of your ownership of the Ordinary Shares acquired upon exercise of your Option will be immediately subject to the Company’s
Right of First Refusal (as defined below) with the same force and effect as the shares subject to the Right of First Refusal immediately before such event. 

(ii)    For a period of 30 calendar days after the Notice Date, or such longer period as may be required to avoid
the classification of your Option as a liability for financial accounting purposes, the Company will have the Option to purchase all (but not less than all) of the Offered Shares at the purchase price and on the terms set forth in
Section 11(a)(iii) (the Company’s “Right of First Refusal”). In the event that the proposed Transfer is one involving no payment of a purchase price, the purchase price will be deemed to be the Fair Market Value of
the Offered Shares as determined in good faith by the Board in its discretion. The Company may exercise its Right of First Refusal by mailing (by registered or certified mail) written notice of exercise of its Right of First Refusal to the Offeror
prior to the end of said 30 days (including any extension required to avoid classification of the Option as a liability for financial accounting purposes). 

(iii)    The price at which the Company may purchase the Offered Shares pursuant to the exercise of its Right of
First Refusal will be the cash price offered for the Offered Shares 












 
by the proposed transferee (as set forth in the notice required under Section 11(a)(i)), or the Fair Market Value as determined by the Board in the event no purchase price is involved. To
the extent consideration other than cash is offered by the proposed transferee, the Company will not be required to pay any additional amounts to the Offeror other than the cash price offered (or the Fair Market Value, if applicable). The
Company’s notice of exercise of its Right of First Refusal will be accompanied by full payment for the Offered Shares and, upon such payment by the Company, the Company will acquire full right, title and interest to all of the Offered Shares.

 (iv)    If, and only if, the Option given pursuant to Section 11(a)(ii) is not exercised, the Transfer
proposed in the notice given pursuant to Section 11(a)(i) may take place; provided, however, that such Transfer must, in all respects, be exactly as proposed in said notice except that such Transfer may not take place either before the
10th calendar day after the expiration of the 30 day Option exercise period or after the ninetieth 90th calendar day after the expiration of
the 30 day Option exercise period, and if such Transfer has not taken place prior to said 90th day, such Transfer may not take place without once again complying with this Section 11(a). The
Option exercise periods in this Section 11(a)(iv) will be adjusted to include any extension required to avoid the classification of your Option as a liability for financial accounting purposes. 

(b)    As used in this Section 11, the term “Transfer” means any sale, encumbrance,
pledge, gift or other form of disposition or transfer of Ordinary Shares or any legal or equitable interest therein; provided, however, that the term Transfer does not include a transfer of such shares or interests by will or intestacy to
your Immediate Family (as defined below). In such case, the transferee or other recipient will receive and hold the Ordinary Shares so transferred subject to the provisions of this Section, and there will be no further transfer of such shares except
in accordance with the terms of this Section 11. As used herein, the term “Immediate Family” will mean your spouse, the lineal descendant or antecedent, father, mother, brother or sister, child, adopted child, grandchild
or adopted grandchild of you or your spouse, or the spouse of any child, adopted child, grandchild or adopted grandchild of you or your spouse. 

(c)    None of the Ordinary Shares purchased on exercise of your Option will be transferred on the Company’s
books nor will the Company recognize any such Transfer of any such shares or any interest therein unless and until all applicable provisions of this Section 11 have been complied with in all respects. The certificates of stock evidencing
Ordinary Shares purchased on exercise of your Option will bear an appropriate legend referring to the transfer restrictions imposed by this Section 11. 

(d)    To ensure that the shares subject to the Company’s Right of First Refusal will be available for
repurchase by the Company, the Company may require you to deposit the certificates evidencing the shares that you purchase upon exercise of your Option with an escrow agent designated by the Company under the terms and conditions of an escrow
agreement approved by the Company. If the Company does not require such deposit as a condition of exercise of your Option, the Company reserves the right at any time to require you to so deposit the certificates in escrow. As soon as practicable
after the expiration of the Company’s Right of First Refusal, the agent will deliver to you the shares and any other property no longer subject to such restriction. In the event the shares and any other property held in escrow are subject to
the Company’s exercise of its Right of First Refusal, the notices required to be given to you will be given to the escrow agent, and any payment required to be given to you will be given to the escrow agent. Within 30 days after payment by the
Company for the Offered Shares, the escrow agent will deliver the Offered Shares that the Company has repurchased to the Company and will deliver the payment received from the Company to you. 

12.    RIGHT OF REPURCHASE. To the extent
provided in the Company’s Constitution in effect at such time the Company elects to exercise its right, the Company (or its designee as applicable) will have the right to repurchase all or any part of the Ordinary Shares you acquire pursuant to
the exercise of your Option. 












 13.    COMPULSORY TRANSFER
OF SHARES ON CESSATION OF CONTINUOUS SERVICE.    Ordinary Shares that you acquire upon exercise of your Option
may be subject to compulsory transfer provisions upon cessation of your Continuous Service in accordance with any such provisions that are contained in the Company’s Constitution at the time of such cessation; provided, however, that if there
is no such compulsory transfer described in the Company’s Constitution at such time, the compulsory transfer provisions described below will apply. These compulsory transfer provisions will 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 (the “Listing Date”). 

(a)    Prior to the Listing Date, if your Continuous Service ceases for whatever reason then if the Board so determine in
their absolute discretion at any time thereafter, the Board may direct you in writing to serve a notice of transfer offering all Shares held by you at that time (together the “Leaver Shares”) for sale. If you fail to serve a transfer
notice within 10 Business Days of first being notified of this obligation to do so any director shall be deemed appointed hereunder as your attorney with authority in your name and on your behalf to serve a notice of transfer in respect of such
Leaver Shares at any time thereafter and to execute and sign any and all agreements, instruments, deeds or other papers and documents and do all things in his name as the Company may in its absolute discretion consider necessary or desirable. 

(b)    Where Continuous Service ceases other than for Cause, the sale price of the Leaver Shares shall be the Fair Market
Value of the Leaver Shares. 
 (c)    Where Continuous Service ceases for Cause, the sale price of the Leaver Shares
shall be the lesser of (i) the aggregate of the amount paid by you on acquisition of the Leaver Shares being sold and (ii) the Fair Market Value of the Leaver Shares. 

14.    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 Company or an
Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your Option will obligate the Company or an Affiliate, their respective shareholders, 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. 

15.    WITHHOLDING OBLIGATIONS. 

(a)    At the time you exercise your Option, in whole or in part, and 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 “same day sale” pursuant to a program developed under Regulation T as
promulgated by the U.S. 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)    If this Option is a Nonstatutory Stock Option, then upon your request
and subject to approval by the Company, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested Ordinary Shares otherwise issuable to you upon the exercise of your Option a number of whole
Ordinary Shares 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 Ordinary Shares 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, Ordinary Shares shall be withheld solely from fully vested Ordinary Shares 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 will have no obligation to issue a certificate for such Ordinary Shares or release such Ordinary Shares from any
escrow provided for herein, if applicable, unless such obligations are satisfied. 
 16.    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 will 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 Ordinary Shares on the Date of Grant and there is no other impermissible deferral of compensation
associated with the Option. Because the Ordinary Shares are 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 U.S. Internal Revenue Service will agree with the valuation as determined by the Board, and you will not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates
in the event that the U.S. Internal Revenue Service asserts that the valuation determined by the Board is less than the “fair market value” as subsequently determined by the U.S. Internal Revenue Service. 

17.    NOTICES. Any notices provided for in your Option, the Grant Notice,
this Option Agreement or the Plan will be given in writing (including electronically) and will be deemed effectively given when personally delivered, when sent by fax or electronic mail (transmission confirmed), when actually delivered if sent
express overnight courier service or five days after deposit in first class 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 another third party designated by the Company. 

18.    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 this Option Agreement 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 Dodd–Frank Wall Street Reform and Consumer Protection Act, if applicable, and any implementing regulations thereunder, any clawback policy adopted by the Company and any compensation recovery policy
otherwise required by applicable law. 












 19.    SEVERABILITY. If all
or any part of this Option 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 Option Agreement or the Plan not declared to be
unlawful or invalid. Any Section of this Option 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. 
 20.    WAIVER. You acknowledge
that a waiver by the Company of breach of any provision of the Option Agreement shall not operate or be construed as a waiver of any other provision of the Option Agreement, or of any subsequent breach of the Option Agreement.

 I hereby make the following certifications and representations with respect to the number of
Shares listed above, 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 U.S. Securities Act of 1933, as amended (the “Securities Act”), and are deemed to constitute “restricted securities” under Rule 701 and 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 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 shall have endorsed thereon
appropriate legends reflecting the foregoing limitations, as well as any legends reflecting restrictions pursuant to the Company’s Constitution 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 with respect to any Ordinary Shares or other securities of the Company for a period of one hundred 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 shall request to facilitate compliance with FINRA Rule 2711 or NYSE Member Rule 472 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.
