INSMED INCORPORATED

NON-QUALIFIED STOCK OPTION AGREEMENT

UNDER THE AMENDED AND RESTATED 2019 INCENTIVE PLAN

FOR U.S. PARTICIPANTS

No. of shares subject to Option: /$AwardsGranted$/

THIS NON-QUALIFIED STOCK OPTION AGREEMENT (this “Agreement”) dated this /$GrantDate$/, between INSMED INCORPORATED, a Virginia corporation (the "Company"), and /$ParticipantName$/ ("Participant"), is made pursuant and subject to the provisions of the Insmed Incorporated Amended and Restated 2019 Incentive Plan, as amended (the "Plan"), a copy of which has been made available to Participant.  All terms used herein that are defined in the Plan have the same meaning given them in the Plan.

If and to the extent that this Agreement conflicts or is inconsistent with the terms, conditions and provisions of any employment, consulting or similar services agreement between Participant and the Company (or any of its Affiliates, as applicable) as may be in effect (the “Service Agreement”), the Service Agreement shall control, and this Agreement shall be deemed to be modified accordingly so long as such modification is not expressly prohibited by the Plan.

1.Grant of Option.  Pursuant to the Plan, the Company, on /$GrantDate$/ (the "Date of Grant"), granted to Participant, subject to the terms and conditions of the Plan and subject further to the terms and conditions herein set forth, the right and Option to purchase from the Company all or any part of an aggregate of /$AwardsGranted$/ shares of Common Stock at the Option price of /$GrantPrice$/ per share, being not less than the Fair Market Value of such shares on the Date of Grant.  This Option is intended to be a nonqualified stock option and not an "incentive stock option" within the meaning of Section 422 of the Code.  This Option is exercisable as hereinafter provided.

2.Terms and Conditions.  This Option is subject to the following terms and conditions:

a.Expiration Date.  This Option shall expire ten years from the Date of Xxxxx (the "Expiration Date").

b.Exercise of Option.  Except as provided in paragraphs 3, 4 and 5, this Option shall be exercisable with respect to twenty-five percent (25%) of the shares of Common Stock subject to this Option on the first annual anniversary of the first day of the month immediately following the Date of Grant (the “First Vesting Date”) and with respect to an additional twelve and a half percent (12.5%) of the shares of Common Stock subject to this Option on the six-month anniversary of the First Vesting Date and each six-month anniversary date thereafter through the fourth annual anniversary of the first day of the month immediately following the Date of Xxxxx. If the foregoing schedule would produce fractional shares, the number of shares for which the Option becomes exercisable shall be

rounded down to the nearest whole share. Once this Option has become exercisable in accordance with this subparagraph 2(b) it shall continue to be exercisable until the termination of Participant's rights hereunder pursuant to paragraph 3, 4 or 5 or until the Option has expired pursuant to subparagraph 2(a).  A partial exercise of this Option shall not affect Participant's right to exercise this Option with respect to the remaining shares, subject to the conditions of the Plan and this Agreement.

c.Method of Exercising Option and Payment for Shares.  This Option shall be exercised by written notice delivered to the attention of the Company's Chief Financial Officer at the Company's principal office in New Jersey.  The exercise date shall be (i) in the case of notice by mail, the date of postmark, or (ii) if delivered in person, the date of delivery.  Such notice shall be accompanied by payment of the Option price in full, in cash or cash equivalent acceptable to the Committee, or such other method as determined by the Committee, including an irrevocable commitment by a broker to pay over such amount from a sale of the shares of Common Stock issuable under the Option, the delivery of previously owned shares of Common Stock or withholding of shares of Common Stock deliverable upon exercise which, together with any cash or cash equivalent paid, is not less than the Option price for the number of shares for which this Option is being exercised.

d.Agreement with Terms. Execution of this Agreement by Participant or receipt of any benefits under this Agreement by Participant shall constitute Participant’s acknowledgement of and agreement with all of the provisions of this Agreement and of the Plan that are applicable to this Option, and the Company shall administer this Agreement accordingly.

e.Termination of Employment or Service; Forfeiture. Except as provided in this subparagraph 2(e), in the event of Participant’s termination of employment or service, any vested portion of this Option that is not exercised during the period specified in paragraph 3, paragraph 4 or paragraph 5 of this Agreement, as applicable, shall be forfeited upon the expiration of such period, and any portion of this Option that is unvested as of the date of Participant’s termination of employment or service shall be forfeited on such date. Notwithstanding the preceding sentence, if Participant’s employment or service terminates prior to the Expiration Date on account of Participant’s death or Participant becoming permanently and totally disabled within the meaning of Section 22(e)(3) of the Code (“Permanently and Totally Disabled”), then any unvested portion of this Option shall immediately become vested and exercisable on Participant’s termination date.

f.Change in Status. A change in the status (whether as employee, member of the Board or other non-employee advisor or service provider) in which Participant renders service to the Company and its Affiliates or a change in the entity for which Participant renders such service shall not constitute a termination of Participant’s employment or service for purposes of this Agreement, so long as there is no interruption or termination of Participant’s services to the Company and its Affiliates; provided, however, that if the entity employing or engaging Participant ceases to be an Affiliate of the Company, as determined by the Administrator, Participant’s employment or service shall be considered to have terminated on the date such entity ceased to be an Affiliate.

3.Exercise in the Event of Death.  In the event Participant dies before the expiration of this Option pursuant to subparagraph 2(a), this Option shall be exercisable with respect to all or part of the shares of Common Stock that Participant was entitled to purchase under subparagraph 2(b) and subparagraph 2(e) on the date of Participant’s death.  In that event, this Option may be exercised, to the extent exercisable, by Participant's estate or by the person or persons to whom his rights under this Option shall pass by will or the laws of descent and distribution.  Participant's estate or such persons may exercise this Option within one (1) year after Participant's death or during the remainder of the period preceding the Expiration Date, whichever is shorter.

4.Exercise in the Event of Permanent and Total Disability.  In the event Participant becomes Permanently and Totally Disabled before the expiration of this Option pursuant to subparagraph 2(a), this Option shall be exercisable with respect to all or part of the shares of Common Stock that Participant was entitled to purchase under subparagraph 2(b) and subparagraph 2(e) on the date he ceases to be employed or engaged by the Company and its Affiliates as a result of his becoming Permanently and Totally Disabled. In that event, Participant may exercise this Option, to the extent exercisable, within one (1) year after the date he ceases to be employed or engaged by the Company and its Affiliates as a result of his becoming Permanently and Totally Disabled or during the period preceding the Expiration Date, whichever is shorter.

5.Exercise After Termination of Employment or Service.  Except as provided in paragraphs 3 and 4 hereof, if Participant ceases to be employed or engaged by the Company and its Affiliates prior to the Expiration Date, this Option shall be exercisable for all or part of the number of shares that Participant was entitled to purchase under subparagraph 2(b), as well as set forth under any Service Agreement, on the date of Participant’s termination of employment or service. In that event, Participant may exercise this Option, to the extent exercisable under subparagraph 2(b) and/or under any Service Agreement, during the remainder of the period preceding the Expiration Date or until the date that is three (3) months (or such other period of time provided under any Service Agreement) after the date he ceases to be employed or engaged by the Company and its Affiliates, whichever is shorter.

6.Notice.  Any notice or other communication given pursuant to this Agreement shall be in writing and shall be personally delivered or mailed by United States registered or certified mail, postage prepaid, return receipt requested, to the Company at its principal place of business or to Participant at the address on the payroll records of the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing.  Additionally, if such notice or communication is by the Company to Participant, the Company may provide such notice electronically (including via email). Any such notice shall be deemed to have been given (a) on the date of postmark, in the case of notice by mail, or (b) on the date of delivery, if delivered in person or electronically.

7.Fractional Shares.  Fractional shares shall not be issuable hereunder, and when any provision hereof may entitle Participant to a fractional share such fraction shall be disregarded.

Participant shall, not later than the date as of which the receipt of this Award becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, local or other taxes required by law to be withheld on account of such taxable event. The Company shall have no obligation to deliver shares of Common Stock until such withholding requirements have been fully satisfied by Participant.

b.Tax Obligations. Nothing in the Plan or in this Agreement shall be interpreted or construed to transfer any liability for any tax (including, without limitation, a tax or penalty due as a result of a failure to comply with Section 409A of the Code) due by Participant to the Company, any Subsidiary or Affiliate, or to any other individual or entity, and the Company shall have no liability to Participant, or any other party, thereto. Participant acknowledges that the Company and its Subsidiaries and Affiliates: (a) make no representations or undertakings regarding the tax treatment in connection with any aspect of the Option; and (b) do not commit to structure the terms of the grant or any other aspect of the Option to reduce or eliminate Participant’s tax liabilities.

9.No Right to Continued Employment or Other Service. Nothing in the Plan or this Agreement shall interfere with or limit in any way the right of the Company, its Subsidiaries and/or its Affiliates to terminate Participant’s employment at any time or for any reason in accordance with the Company’s Bylaws, governing law and any applicable Service Agreement, nor shall any terms of the Plan or this Agreement confer upon Participant any right to continue his or her employment for any specified period of time. Neither this Agreement nor any benefits arising under the Plan or this Agreement shall constitute an employment contract or service contract with the Company, any Subsidiary and/or its Affiliates. If Participant is not an

employee, nothing in the Plan or this Agreement shall interfere with or limit in any way the right of the Company, its Subsidiaries and/or its Affiliates to terminate Participant’s service, (i) if a member of the Board, on the Board at any time or for any reason in accordance with the Company’s Bylaws and governing law, or (ii) if a non-employee consultant or advisor, in accordance with the terms of the contract with such consultant or advisor. In no event shall any of the terms of the Plan or this Agreement itself confer upon Participant any right to continue his or her service for any specified period of time.

10.Adjustments Upon Certain Unusual or Nonrecurring Events or Other Events. Upon certain unusual or nonrecurring events, or other events, the terms of this Option shall be adjusted by the Administrator pursuant to Section 14 of the Plan.
