▇▇▇▇▇.▇▇▇▇▇▇▇▇@▇▇▇▇▇▇▇▇▇.▇▇▇

Dear ▇▇▇▇▇,

This Retention Agreement (this “Agreement”) is being provided to you in furtherance of our prior discussions regarding your transition from the position of President and Chief Operating Officer (“President”) of Dermavant Sciences, Inc. (“Dermavant” or the “Company”). Consistent with such discussions, this Agreement sets forth the terms for the continuation of your employment with the Company for a transitional period extending through January 4, 2019 (such date being referred to as the “Termination Date”). Further, this Agreement sets forth the additional pay and benefits the Company is offering you in connection with your continuation of employment through the Termination Date on the terms and conditions set forth herein, and in consideration for making and honoring certain commitments, including agreeing not to pursue legal action against the Company as described in Sections 5 and 6. The additional pay and benefits provided herein is subject to your execution of this Agreement without revocation.

Whether or not you enter into this Agreement, the status of your employment with the Company will be as set forth below, and you will receive the following upon the termination of your employment with the Company:

In order to enter into this Agreement, you must sign and date the Agreement, and return the executed Agreement to me by December 25, 2018, unless such period is extended in writing by the Company. If I do not receive the signed and dated Agreement by that date, the offer will be deemed withdrawn, this Agreement will not take effect and you will not receive the pay and benefits described in Section 1. In addition, as set forth in Section 2.a. above, your employment will remain at-will, your employment may be immediately terminated by the Company, and/or the Company may transition your role from that of President/COO.

By entering into this Agreement, you are agreeing:

While it is very important that you read this entire Agreement carefully, it is especially important that you read this Section carefully, because it lists important rights you are giving up if you decide to enter into this Agreement.

Who And What Does The Release Cover?

What Are You Giving Up? It is the Company’s position that you have no legitimate basis for bringing a legal action against it. You may agree or believe otherwise or simply not know. However, if you Execute this Agreement, subject to the Company’s compliance with Section 1.a.i. and 1.a.ii., you agree, except for certain exceptions described in Section 9, to give up your ability to bring a legal action against the Company and others, including, but not limited to its affiliates. More specifically, by Executing this Agreement, except as specifically set forth herein, subject to the Company’s compliance with Section 1.a.i. and 1.a.ii., you agree to give up any right you may have to bring various types of “Claims,” which means possible lawsuits, claims, demands and causes of action of any kind (based on any legal or equitable theory, whether contractual, common-law, statutory, federal, state, local or otherwise), whether known or unknown, by reason of any act or omission up to and including the date on which you Execute this Agreement. You also agree to give up potential Claims arising under any contract or implied contract, including but not limited to your Transfer Letter or any handbook, tort law or public policy having any bearing on your employment or the termination of your employment, such as Claims for wrongful discharge, discrimination, hostile work environment, breach of contract, tortious interference, harassment, bullying, infliction of emotional distress, defamation, back pay, vacation pay, sick pay, wage, commission or bonus payment, equity grants, stock options, restricted stock option payments, payments under any bonus or incentive plan, attorneys’ fees, costs and future wage loss. This Agreement includes

a release of your right to assert a Claim of discrimination on the basis of age, sex, race, religion, national origin, marital status, sexual orientation, gender identity, gender expression, ancestry, parental status, handicap, disability, military status, veteran status, harassment, retaliation or attainment of benefit plan rights. However, as described in Section 9, this Agreement does not and cannot prevent you from asserting your right to bring a claim against the Company and Releasees, as defined below, before the Equal Employment Opportunity Commission or other agencies enforcing non-discrimination laws or the National Labor Relations Board.

Whose Possible Claims Are You Giving Up? You agree to waive Claims that you may otherwise be able to bring. You not only agree that you will not personally bring these Claims in the future, but that no one else will bring them in your place, such as your heirs and executors, and your dependents, legal representatives and assigns. Together, you and these groups of individuals are referred to in the Agreement as“Releasors.”

Who Are You Releasing From Possible Claims? You not only agree to waive Claims that you and the Releasors may otherwise be able to bring against the Company, but also Claims that could be brought against “Releasees,” which means the Company and all of their past, present and future:

Possible Claims You May Not Know. It is possible that you may have a Claim that you do not know exists. By entering into this Agreement, you agree to give up all Claims that you ever had including Claims arising out of your employment or the termination of your employment. Even if Claims exist that you do not know about, you agree to give them up.

What Types of Claims Are You Giving Up? In exchange for the pay and benefits in Section 1, you (on behalf of yourself and the Releasors) forever release and discharge the Company and all of the Releasees from any and all Claims including Claims arising under the following laws (including amendments to these laws):

Federal Laws, such as:

State and Municipal Laws, such as:

You Are Giving Up Potential Remedies and Relief. You agree to waive any relief that may be available to you (such as money damages, equity grants, benefits, attorneys’ fees, and equitable relief such as reinstatement) under any of the waived Claims, except as provided in Section 9.

This Release Is Extremely Broad. This release is meant to be as broad as legally permissible and applies to both employment-related and non-employment-related Claims up to the time that you execute this Agreement. This release includes a waiver of jury trials and non-jury trials. This Agreement does not release or waive Claims or rights that, as a matter of law, cannot be waived, which include, but are not necessarily limited to, the exceptions to your release of claims or covenant

not to sue referenced in Section 9. Additionally, you are not waiving (i) any right to the rights, payments or benefits to which you are entitled under this Agreement, (ii) any claim relating to directors’ and officers’ liability insurance coverage or any right of indemnification under applicable law or the Company’s organizational documents or otherwise (which such rights shall continue and survive the execution of this Agreement and your termination of service with the Company), or (iii) any rights you may have as a member or holder of equity or other securities of the Company or its affiliates (subject to the provisions and agreements set forth herein) (the foregoing, together with the compensation and benefits specified in Section 2 hereof and the other matters not released hereunder, collectively, the “Excluded Claims”).

The Company is not aware after reasonable inquiry as of the date hereof of any Claims that the Company or any of its Affiliates may have against you.

Except as provided in Section 9, you agree not to sue or otherwise bring any legal action against the Company or any of the Releasees ever for any Claim released in Section 5 arising before you Execute this Agreement. You are not only waiving any right you may have to proceed individually, but also as a member of a class or collective action. You waive any and all rights you may have had to receive notice of any class or collective action against Releases for claims arising before you Execute this Agreement. In the event that you receive notice of a class or collective action against Releasees for claims arising before you Execute this Agreement, you must “opt out” of and may not “opt in” to such action. You are also giving up any right you may have to recover any relief, including money damages, from the Releasees as a member of a class or collective action.

You represent that you are not aware of any facts that might justify a Claim by you against the Company for any violation of the Family and Medical Leave Act (“FMLA”). You also represent that you have received all wages for all work you performed and any commissions, bonuses, stock options, restricted stock option payments, overtime compensation and FMLA leave to which you may have been entitled up to the date of this Agreement, except for accrued and unpaid salary and as set forth in this Agreement, and that you are not aware of any facts constituting a violation by the Company or Releasees of any violation of the Fair Labor Standards Act or any other federal, state or municipal laws.

You represent that you have not sued or otherwise filed any actions (or participated in any actions) of any kind against the Company or Releasees in any court or before any administrative or investigative body or agency. The Company is relying on this assurance in entering into this Agreement.

In Sections 5 and 6, you are releasing Claims and agreeing not to sue, but there are exceptions to those commitments. Specifically, nothing in this Agreement prevents you from bringing a legal action or otherwise taking steps to:

For purposes of clarity, this Agreement does not limit your or the Company’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. This Agreement does not limit your right to receive an award for information provided to any Government Agencies.

You acknowledge and re-affirm your obligations pursuant to the NDA and specifically with respect to Sections 2, 3 and 4 thereof, without limitation. In addition, you agree not to disclose the existence or terms of this Agreement without the prior written consent of the Company, except: (a) to your spouse, domestic partner or immediate family member; (b) to the extent required by law; (c) in connection with any claim to enforce, interpret or determine the scope, meaning, enforceability or effect of the Agreement; (d) to obtain confidential legal, tax or financial advice with respect thereto; (e) in connection with the exceptions set forth in Section 9 above; or (f) as may be previously publicly disclosed by the Company in its public filings with the Securities and Exchange Commission.

Pursuant to the Defend Trade Secrets Act of 2016, you acknowledge and understand that you will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of the trade secrets of the Company or any of its affiliates that is made by you (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.

As of your Termination Date, you agree that you have returned to the Company all property belonging to the Company including, but not limited to, electronic devices, equipment, access cards, and paper and electronic documents obtained in the course of your employment, except as may be specifically agreed to by the Company in writing; provided however, that you may retain (and make copies of) your address book, and correspondence, files and documents relating to your equity rights, personal compensation, benefits, and obligations.

You acknowledge that, prior to the termination of your employment with the Company, you disclosed to the Company, in accordance with applicable policies and procedures, any and all information relevant to any investigation of the Company’s business practices conducted by any governmental agency or to any existing, threatened or anticipated litigation involving the Company, whether administrative, civil or criminal in nature, and that you are otherwise unaware of any wrongdoing committed by any current or former employee of the Company that has not been disclosed. Nothing in this Agreement shall prohibit or restrict you or the Company from (1) making any disclosure of information required by law; (2) providing information to, or testifying or otherwise assisting in any investigation or proceeding brought by any federal or state regulatory or law enforcement agency or legislative body, any self-regulatory organization, or with respect to any internal investigation by the Company or its affiliates; or (3) testifying, participating in or otherwise assisting in a proceeding relating to an alleged violation of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002, the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act, any federal, state or municipal law relating to fraud, or any rule or regulation of any self-regulatory organization.

You agree that you will not, through any medium including, but not limited to, the press, Internet or any other form of communication, intentionally or negligently disparage, defame, or otherwise damage or assail the reputation, integrity or professionalism of the Company, its affiliated companies or any director or officer of the Company or any of its affiliated companies. The Company shall not make or authorize any public statements or comments that disparage you. Nothing in this Section 13 is intended to restrict or impede either party’s participation in proceedings or investigations brought by or before the EEOC, NLRB, or other federal, state or local government agencies, or otherwise exercising protected rights to the extent that such rights cannot be waived by agreement, including Section 7 rights under the National Labor Relations Act.

If you breach any section of this Agreement, including without limitation, Section 5, 6, 10, 11, or 13 the Company will be entitled to all relief legally available to it including equitable relief such as injunctions, and the Company will not be required to post a bond. For the avoidance of doubt, any material breach by you of this Agreement shall constitute cause for purposes of termination of the Agreement by the Company.

This Agreement is governed by New York law, without regard to conflicts of laws principles.

This Agreement is binding on the Parties and their heirs, executors, successors and assigns.

If a court with jurisdiction to consider this Agreement determines that any provision is illegal, void or unenforceable, that provision will be invalid. However, the rest of the Agreement will remain in full force and effect. A court with jurisdiction to consider this Agreement may modify invalid provisions if necessary to achieve the intent of the Parties.

By entering into this Agreement, neither you nor the Company admits wrongdoing of any kind.

You acknowledge and agree that:

YOU AGREE THAT ANY MODIFICATIONS, MATERIAL OR OTHERWISE, MADE TO THIS AGREEMENT DO NOT RESTART, EXTEND OR AFFECT IN ANY MANNER THE ORIGINAL TWENTY-ONE (21) CALENDAR DAY REVIEW PERIOD DESCRIBED ABOVE WHICH COMMENCED ON DECEMBER 4, 2018.

(b) All Inventions will be deemed “work made for hire” as that term is used in the U.S. Copyright Act, and belong solely to the Company from conception. I hereby expressly disclaim all interest in all Inventions. To the extent that title to any Invention or any materials comprising or including any Invention is found not be a “work made for hire” as a matter of law, I hereby irrevocably assign to the Company all of my right, title and interest to that Invention. At any time during or after my employment with the Company that the Company requests, I will sign whatever written documents of assignment are necessary to formally evidence my irrevocable assignment to the Company of any Invention.

(c) At all times during or after my employment with the Company I will assist the Company in obtaining, maintaining and renewing patent, copyright, trademark and other appropriate protection for any Invention, in the United States and in any other country, at the Company’s expense.

3.3 Excluded Information. On Exhibit A attached to this agreement I have included a complete list, with nonconfidential descriptions, of any inventions, ideas, reports and other creative works that I made or conceived prior to my employment with the Company (collectively, the “Excluded Information”). I intend that the items on that list and only the items on that list shall be excluded from the restrictions set forth in this agreement. I will not assert any right, title or interest in or to any Invention or claim that I made, conceived or acquired any Invention before my employment with the Company unless I have specifically identified that Invention on the attached Exhibit A. In the event that any Excluded Information is incorporated into any Invention, I hereby grant Company a perpetual, worldwide, royalty free, non-exclusive license to use and reproduce the Excluded Information for commercial, internal business and all other purposes.

4. Non-Solicitation. In order to protect the legitimate business interests of the Company and in consideration of the Company’s willingness to provide to me access to its Confidential Information, I agree that during the period beginning on the initial date of my employment with the Company and ending one (1) year after termination of my employment with the Company for any reason, I will not directly or indirectly, whether as owner, sole proprietor, partner, shareholder, director, member, consultant, agent, founder, co-venture partner or otherwise, (i) do anything to divert or attempt to divert from the Company any business of any kind, including, without limitation, solicit or interfere with any of the Company’s customers, clients, members, business partners or suppliers, or (ii) solicit, induce, recruit or encourage any person engaged or employed by the Company to terminate his or her employment or engagement.

If any provision is held to be unenforceable as written, it shall be enforced to the fullest extent permitted under applicable law. In the event that one or more of the provisions contained in this agreement shall for any reason be held unenforceable in any respect under the law of any state of the United States or the United States, then it shall (a) be enforced to the fullest extent permitted under applicable law and (b) such unenforceability shall not affect any other provision of this agreement, but this agreement shall then be construed as if such unenforceable portion(s) had never been contained herein.

5.2 Remedies. I understand and agree that if I breach or threaten to breach any of the provisions of this agreement the Company would suffer immediate and irreparable harm and that monetary damages would be an inadequate remedy. I agree that, in the event of my breach or threatened breach of any of the provisions of this agreement, the Company shall have the right to seek relief from a court to restrain me (on a temporary, preliminary and permanent basis) from using or disclosing Company Confidential Information or Inventions or otherwise violating the provisions of this agreement, and that any such restraint shall be in addition to (and not instead of) any and all other remedies to which the Company shall be entitled, including money damages. The Company shall not be required to post a bond to secure against an imprudently granted injunction (whether temporary, preliminary or permanent).

5.3 Governing Law; Jury Waiver; Consent to Jurisdiction. This agreement (together with any and all modifications, extensions and amendments of it) and any and all matters arising directly or indirectly herefrom shall be governed by and construed and enforced in accordance with the internal laws of the state of New York applicable to agreements made and to be performed entirely in such state, without giving effect to the conflict or choice of law principles thereof. For all matters arising directly or indirectly from this Agreement (“Agreement Matters”), I hereby (a) irrevocably consent and submit to the sole exclusive jurisdiction of the United States District Court for the Southern District of New York and any state court in the state of New York that is located in the Manhattan county of New York (and of the appropriate appellate courts from any of the foregoing) in connection with any legal action, lawsuit, arbitration, mediation, or other legal or quasi legal proceeding (“Proceeding”) directly or indirectly arising out of or relating to any Agreement Matter; provided that a party to this Agreement shall be entitled to enforce an order or judgment of any such court in any United States or foreign court having jurisdiction over the other party, (b) irrevocably waive, to the fullest extent permitted by law, any objection that I may now or later have to the laying of the venue of any such Proceeding in any such court or that any such Proceeding which is brought in any such court has been brought in an inconvenient forum, (c) irrevocably waive, to the fullest extent permitted by law, any immunity from jurisdiction of any such court or from any legal process therein, (d) irrevocably waive, to the fullest extent permitted by law, any right to a trial by jury in connection with a Proceeding, (e) covenant that I will not, directly or indirectly, commence any Proceeding other than in such courts and (f) agree that service of any summons, complaint, notice or other process relating to such Proceeding may be effected in the manner provided for the giving of notice as set forth in this agreement.

ATTACHMENT I

OPTION AGREEMENT

DERMAVANT SCIENCES LTD.

(F/K/A ROIVANT DERMATOLOGY LTD.)

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 “Option Agreement”), Dermavant Sciences Ltd., f/k/a Roivant Dermatology Ltd., (the “Company”) has granted you an option under its 2016 Equity Incentive Plan (the “Plan”) to purchase the number of common shares of the Company (the “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 Option Agreement and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option 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.

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 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 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. EXERCISE PRIOR TO VESTING (“EARLY EXERCISE”). If permitted in your Stock Option 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:

I-1

(a) a partial exercise of your option will 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 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 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 $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 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 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. SECURITIES LAW 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

I-2

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 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) the Expiration Date indicated in your Stock Option Grant Notice; and

(c) the day before the tenth (10th) anniversary of the Date of ▇▇▇▇▇.

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 (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 Stock Option 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 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 withholding obligation of the Company arising by reason of (i) the exercise of your option, or (ii) 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 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.

I-3

(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 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 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 regulation (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 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 will be entitled to exercise this option and receive, on behalf of your estate, the Common Stock or other consideration resulting from such exercise.

I-4

11. 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 shall determine.

12. 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 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.

13. 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 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 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). 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 shares of Common Stock or release such shares of Common Stock from any escrow provided for herein, if applicable, unless such obligations are satisfied.

14. 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,

I-5

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 Stock Option Grant Notice is at least equal to the “fair market value” per share of Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with the option. Because the Common Stock 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 will 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.

15. 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 another third party designated by the Company.

This Restricted Stock Unit Award Agreement (“RSU Award Agreement”), dated as of the Grant Date set forth in the Restricted Stock Unit Grant Notice to which this RSU Award Agreement is attached (the “Grant Notice”), is made between Roivant Sciences Ltd. and the Participant designated in the Grant Notice. The Grant Notice and the RSU Award Agreement, collectively, are referred to herein as this “Agreement.”

1. Definitions. Capitalized terms used but not defined herein have the meaning set forth in the Plan or the Grant Notice, as applicable.

2. Grant of Restricted Stock Units. Subject to the provisions of this Agreement and the provisions of the Plan, the Company hereby grants to the Participant the number of RSUs set forth in the Grant Notice.

3. Period of Restriction. The Period of Restriction with respect to the RSUs shall commence and lapse as set forth in the Grant Notice.

4. Vesting and Forfeiture. If the Participant’s service with the Company or any Subsidiary, as applicable, is terminated for any reason, all RSUs with respect to which the Performance Requirement has not been satisfied as of the date of such termination shall automatically be forfeited upon such termination of service. Upon such a termination of service, any RSUs as to which the Performance Requirement had been satisfied will (if an IPO or Change in Control has not previously occurred) remain outstanding until the first to occur of an IPO, Change in Control, or the Expiration Date. In case of any dispute as to whether a termination of the Participant’s service has occurred, the Committee shall have sole discretion to determine whether such termination has occurred and the effective date of such termination. Further, if an IPO or Change in Control does not occur on or before the Expiration Date, all RSUs (regardless of whether or not, or the extent to which, the Performance Requirement has been previously satisfied as to such RSUs) shall automatically be forfeited upon such Expiration Date. Upon the forfeiture of any RSUs pursuant to this Section 4, the Participant shall have no further right with respect to such RSUs.

5. Settlement of Restricted Stock Units. As soon as reasonably practicable following the Vesting Date, but in no event later than two and a half (2-1/2) months following the end of the year in which the Vesting Date occurs, the Company shall cause to be delivered to the Participant, in full settlement and satisfaction of the vested RSUs, either: (i) the full number of Shares underlying such vested RSUs, (ii) a cash payment in an amount equal to the Fair Market Value of such Shares on the Vesting Date or (iii) a combination of such Shares and cash payment, as the Committee in its sole discretion shall determine, in each case, subject to satisfaction of applicable tax withholding obligations with respect thereto in accordance with Section 6 of this Agreement.    

6. Taxes. Upon settlement of the RSUs, or as of any other date on which the value of any RSUs otherwise becomes includible in the Participant’s gross income for tax purposes, any taxes of any kind required by applicable law to be withheld with respect to such RSUs shall, at the Participant’s election, be satisfied by the Company withholding Shares or cash otherwise deliverable or payable to the Participant pursuant to this Agreement. Any such withholding of Shares or cash under this Section 6 shall be subject to applicable law and subject to any limitations, and pursuant to any procedures, as the Committee may prescribe, based on the Fair Market Value of the Shares on the payment date. The Company or Subsidiary of the Company may, in the discretion of the Committee and in consultation with the Participant, provide for alternative arrangements to satisfy applicable tax withholding requirements in accordance with Section 6 of the Plan. Regardless of any action the Company or any Subsidiary of the Company may take with respect to any or all tax withholding obligations, the Participant acknowledges that the ultimate liability for all such taxes is and remains the Participant’s responsibility (or that of the Participant’s beneficiary).

7. No Rights as a Shareholder Prior to Issuance of Shares. Neither the Participant nor any other person shall become the beneficial owner of the Shares underlying the RSUs, nor have any rights to dividends or other rights as a shareholder with respect to any such Shares, until and after such Shares, if any, have been actually issued to the Participant and transferred on the books and records of the Company or its agent in accordance with the terms of the Plan and this Agreement.

8. Transferability. The RSUs shall not be transferable otherwise than by will or the laws of descent and distribution; provided, however, that the Committee may, in its discretion, permit the RSUs to be transferred subject to such conditions and limitations as may be imposed by the Committee.

9. No Right as Employee or Consultant. Neither the grant of the RSUs nor any terms contained in this Agreement shall (i) affect in any manner whatsoever the right or power of the Company or any Subsidiary of the Company, to terminate the Participant’s service for any reason, with or without cause, (ii) if applicable, affect the Participant’s status as an at-will employee of the Company who is subject to termination of service without cause, (iii) confer upon the Participant any right to remain employed by or in service to the Company or any Subsidiary of the Company, (iv) interfere in any way with the right of the Company or any Subsidiary of the Company at any time to terminate such employment or service, or (v) affect the right of the Company or any Subsidiary of the Company to increase or decrease the Participant’s other compensation.

(i) The RSUs and the obligation of the Company to deliver any Shares or cash hereunder shall be subject in all respects to (a) all applicable federal and state laws, rules and regulations and (b) any registration, qualification, approvals or other requirements imposed by any government or regulatory agency or body which the Committee shall, in its discretion, determine to be necessary or applicable. Moreover, the Company shall not deliver any certificates for Shares to the Participant or any other person pursuant to this Agreement if doing so would be contrary to applicable law. If at any time the Company determines, in its discretion, that the listing, registration or qualification of Shares upon any national securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body, is necessary or desirable, the Company shall not be required to deliver any certificates for Shares to the Participant or any other person pursuant to this Agreement unless and until such listing, registration, qualification, consent or approval has been effected or obtained, or otherwise provided for, free of any conditions not acceptable to the Company.

(ii) If at any time the Shares are not registered under the Securities Act, and/or there is no current prospectus in effect under the Securities Act with respect to the Shares, the Participant shall execute, prior to the delivery of any Shares to the Participant by the Company pursuant to this Agreement, an agreement (in such form as the Company may specify) in which the Participant represents and warrants that the Participant is acquiring the Shares acquired under this Agreement for the Participant’s own account, for investment only and not with a view to the resale or distribution thereof, and represents and agrees that any subsequent offer for sale or distribution of any kind of such Shares shall be made only pursuant to either (a) a registration statement on an appropriate form under the Securities Act, which registration statement has become effective and is current with regard to the Shares being offered or sold; or (b) a specific exemption from the registration requirements of the Securities Act, but in claiming such exemption, the Participant shall, prior to any offer for sale of such Shares, obtain a prior favorable written opinion, in form and substance satisfactory to the Company, from counsel for or approved by the Company, as to the applicability of such exemption thereto.

12. Market Standoff Agreement. The Participant agrees that in connection with any registration of the Company’s securities that, upon the request of the Company or the underwriters managing any public offering of the Company’s securities, the Participant will not sell or otherwise dispose of any Shares without the prior written consent of the Company or such underwriters, as the case may be, for such reasonable period of time after the effective date of such registration as may be requested by such managing underwriters and subject to all restrictions as the Company or the underwriters may specify. The Participant will enter into any agreement reasonably required by the underwriters to implement the foregoing.
