Re:Transition Agreement

Dear June:

This confirms that your employment with MyoKardia, Inc. (the “Company”) will be ending. We appreciate your contributions and wish to make this transition as smooth as possible for both you and the Company.  Consistent with that notion, this letter proposes an agreement (the “Agreement”), under which you will continue to be employed by the Company during a Transition Period (defined below) and, thereafter, you will receive Severance Benefits (defined below) if you enter into this Agreement and satisfy the other conditions that are set forth and defined below.  

Regardless of whether you sign this Agreement:

For your part, regardless of whether enter into this Agreement, you remain bound by the continuing obligations under your December 6, 2016 MyoKardia, Inc. Employee Confidentiality

ACTIVE/101014600.11  

and Assignment Agreement (the “Confidentiality Agreement”).  Notwithstanding anything to the contrary in this Agreement or any other agreement, after the Separation Date, you shall be entitled to retain copies of the following documents or items as your personal property: (i) all employment agreements and documents related to compensation that you and the Company executed in connection with your employment with the Company; (ii) all wage statements and other payroll records issued to you, as well as documents issued to you with regard to your employee benefits and (iii) as otherwise allowed under applicable law.  Further, effective immediately your access to the Company’s systems will be aligned with your transition duties and job search efforts as authorized in writing by the Company’s CEO in line with these requirements. You will not dispose of any other Company property (including information or documents, including computerized data and any copies made of any computerized data or software) except as set forth in the following paragraph.

You agree to return as soon as possible to the Company all Company property, including, without limitation, computer equipment, software, keys and access cards, credit cards, files and any Documents containing information concerning the Company, its business or its business relationships (in the latter two cases, actual or prospective), located upon a reasonable search.  After returning all Documents and Company property, you commit to (with reasonable effort) deleting and finally purging any duplicates of files or documents that may contain Company information from any non-Company computer or other device that remains your property.  In the event that you discover that you continue to retain any such property, you shall promptly return it to the Company.  

The remainder of this letter sets forth the terms of the Agreement.  You acknowledge that you are entering into this Agreement knowingly and voluntarily.  With those understandings, you and the Company agree as follows:

1.Transition Period; Separation from Employment

If you enter into and comply with this Agreement and unless you sooner resign or are terminated by the Company for Cause (as defined below), your at-will employment with the Company will terminate on June 30, 2020 (the “Anticipated Separation Date”).  For purposes of this Agreement, the actual last day of your employment with the Company—whether the Anticipated Separation Date or an earlier date—-shall be referred to as the “Separation Date.” If you do not enter into this Agreement, the Separation Date will be on the next business day following the Consideration Period (as defined in Section 18).  The period from September 30, 2019 through the Separation Date shall be referred to as the “Transition Period.” “Cause” means dismissal as a result of (i) any material breach by you of any written agreement between you and the Company after a period to cure if the breach is curable consistent with Paragraph 10 below; and (ii) the conviction of or plea of nolo contendere by you to a felony or a crime involving moral turpitude.

During the Transition Period, you will retain the title of Executive Vice President and Chief Development Officer unless the Company’s Chief Executive Officer (“CEO”) requests that you resign from that position and become a Senior Advisor on an earlier date.  Regardless of your title, your duties during the Transition Period shall be limited to those duties and responsibilities specifically requested in writing by the CEO (the “Transitional Services”) as consistent with your role and title. You are not authorized to execute your previous job responsibilities during

ACTIVE/101014600.11  

the Transition Period unless requested by the CEO.  The Transitional Services shall be performed at such locations as determined by the CEO . Unless otherwise determined by the CEO, you will also retain such electronic access as is approved by the CEO and use of email on a computer to be provided by the Company.

With respect to compensation, you will continue to receive your base salary (Base Salary”) and you will be eligible for regular employee benefits as currently in effect throughout the Transition Period, provided you will not accrue vacation or other paid time off.  You will also continue to vest in your outstanding restricted stock and stock options consistent with the Equity Documents until the Separation Date. In the event you find another job prior to the Anticipated Separation Date, you must resign from the Company and the Separation Date will be on the date of that resignation.  In the event you resign on or prior to the Anticipated Separation Date and provided you satisfy each of the Severance Conditions (as defined below), you will be entitled to Severance Benefits (as defined in Section 2). You will not be eligible for any bonus, severance pay or benefits or other compensation other than to the extent specifically set forth herein. During the Transition Period you are free to pursue other opportunities and investments provided you continue to comply with this Agreement and the Confidentiality Agreement.

You acknowledge and agreed that you are not entitled to any bonus for 2019, 2020 or otherwise and that the Severance Pay shall be your sole post-employment compensation.  

(b)Health Benefits.  If you elect COBRA continuation coverage, the Company will pay for COBRA coverage through the earliest of the following: (i) June 30, 2020; (ii) the date you become eligible to in fact receive health benefits through another employer; or (iii) the date you otherwise become ineligible for COBRA.  The Company will make COBRA reimbursements to you consistent with the Company’s normal expense reimbursement policy, provided that you submit documentation to the Company substantiating your payments for COBRA coverage.

Background

I, June Lee, acknowledge that I entered into a Transition Agreement (the “Agreement”) with MyoKardia, Inc.

I understand that for this Supplemental Release to become effective, I must sign this Supplemental Release no earlier than the Separation Date and return the signed copy to Ingrid Boyes (333 Allerton Avenue, South San Francisco, CA 94080; ***@***) no later than twenty one (21) days after the Separation Date.  

I acknowledge that I have had had the opportunity to consider this Supplemental Release since first receiving it at the same time I received the Agreement.  I understand that, for the period of seven (7) days from the date when I sign this Supplemental Release, I have the right to revoke this Supplemental Release by written notice to Ms. Boyes, provided that such notice is delivered so that it is received at or before the expiration of the seven (7) day revocation period.  This Supplemental Release shall not become effective or enforceable during the revocation period.  This Supplemental Release shall become effective on the first day following expiration of the revocation period (the “Supplemental Release Effective Date”).  

This Supplemental Release shall be supplemental to the release of claims in Section 3 of the Agreement, which shall remain in full force and effect regardless of whether this Supplemental Release becomes effective.

In consideration for, among other terms, the Severance Benefits (as defined in the Agreement), to which I acknowledge I would otherwise not be entitled, I voluntarily release and forever discharge the Company, its affiliated and related entities (including, without limitation, its parent companies), its and their respective predecessors, successors and assigns, its and their respective current and former officers, directors, managers, , employees, attorneys, accountants and agents of each of the foregoing in their official and personal capacities (collectively referred to as the “Releasees”) generally from all claims, demands, debts, damages and liabilities of every name and nature, known or unknown (“Claims”) that, as of the date when I sign this Supplemental Release, I have, I had, now claim to have or ever claimed to have had against any or all of the Releasees.  This release includes, without limitation, all Claims: my employment with and separation from employment with the Company; of wrongful discharge or violation of public policy; of breach of contract; of defamation or other torts; of retaliation or discrimination under federal, state or local law (including, without limitation, Claims of discrimination or retaliation under the Americans with Disabilities Act, Title VII of the Civil Rights Act of 1964, the Age

A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.

I, being aware of said code section, agree to expressly waive any rights I may have thereunder, as well as under any other statute or common law principles of similar effect.
