 Alvaro Amorrortu 

Dear Alvaro, 
 I am pleased to provide you with
the terms and conditions of your anticipated employment by Solid Biosciences, LLC (the “Company”). 
 1.    Position.
Your initial position will be Senior VP of Operations of the Company, reporting to the Company’s CEO, and you will be located initially in the Company’s office at One Broadway, Cambridge, MA. In addition to performing duties and
responsibilities associated with the position of Senior VP of Operations, from time to time the Company may assign you other duties and responsibilities consistent with such position. As a full-time employee of the Company, you will be expected to
devote your full business time and energies to the business and affairs of the Company. Your performance will be reviewed formally after six months of employment and annually thereafter. 

2.    Starting Date. It is expected that your employment will start on November 30, 2015 (the date on which your employment
starts being referred to herein as the “Start Date”). 
 3.    Compensation. 

 

	 	(a)	Your initial salary will be at the rate of $25,000 per month, annualized at $300,000, and you will be paid on a semi-monthly basis at the rate of $12,500. 


 

	 	(b)	The Company will pay you a signing bonus of $100,000 on your Start Date. If your employment with the Company ends for any reason prior to the first anniversary of the Start Date, you will be required to promptly repay
to the Company the full amount of the signing bonus. To the maximum extent permitted by applicable law, you authorize the Company to deduct as a valid set-off, any unpaid compensation, accrued and unused
vacation pay, unpaid performance bonus/incentive compensation, outstanding business expenses, and/or any other payments or compensation otherwise owed to you by the Company, against the amount of the signing bonus (if any) that you are obligated to
repay to the Company pursuant to this Section 3(b). 









	 	(c)	As an important hire of the Company, promptly following your Start Date you will be awarded at no cost to you, 171,000 Series A Common Units of the Company and 1,388 Class C
Non-Voting Units of Solid GT, LLC (“Solid GT”). 25% of each award will vest on the first anniversary of the Start Date and an additional 2.084% of each award will vest on each monthly anniversary
thereafter, provided you continue to be employed by the Company. In addition, you will be awarded 694 Class C Non-Voting Units of Solid GT upon filing by Solid GT of a valid IND with the US Food and Drug
Administration, and an additional 694 Class C Non-Voting Units of Solid GT upon a qualified IPO or sale of the Company or Solid GT, provided, in each case, you continue to be employed by the Company at
the time. These additional awards will be subject to the same vesting schedule as described above, commencing from the date of achievement of the applicable milestone. These awards are intended to be “profits interests” within the meaning
of IRS Revenue Procedures 93-27 and 2001-43, that allow you to participate in distributions by the Company or Solid GT, as applicable, above a certain threshold amount
determined by the board of managers of the relevant entity. Distributions in respect of your Units in the Company and Solid GT may be subject to limitations as provided in the limited liability company agreements of the Company and Solid GT. You
will be required to execute and become a party to such limited liability company agreements at the time Units are awarded to you. 

  

	 	(d)	You will have the opportunity to earn a bonus of up to twenty percent (20%) of your annual base salary per year, based on the achievement of or progress toward individual departmental and/or corporate objectives and
goals, as determined by the Board of Managers of the Company (the “Board”) in its sole discretion, provided that to be eligible for any such bonus, you must be employed by the Company in good standing at the time such bonus is awarded.


 4.    Benefits. You will be entitled as an employee of the Company to receive such benefits as are generally
provided to its employees and for which you are eligible in accordance with Company policy as in effect from time to time. The Company retains the right to change, add or terminate any particular benefit. You will be eligible for 11 paid holidays
and 3 weeks of paid vacation per year. 
 5.    Termination and Severance.     Your employment may be
terminated by you or the Company as follows: 
  

	 	(a)	the Company may terminate your employment for “Cause” (as defined below) upon written notice to you effectively immediately, in which case you will not be entitled to receive any payment other than your earned
compensation and accrued and unused vacation time through your date of separation; 

  

	 	(b)	you may terminate your employment voluntarily other than for “Good Reason” (as defined below) upon at least thirty (30) days’ prior written notice to the Company, in which case you will not be
entitled to receive any payment other than your earned compensation and accrued and unused vacation time through your date of separation; and

	 	(c)	(i) the Company may terminate your employment other than for “Cause” upon at least thirty (30) days’ prior written notice to you and (ii) you may you terminate your employment voluntarily for

Notwithstanding the foregoing, but subject to Section 6(g), the Company’s obligations to make payments under this Section 6(c) are conditioned upon your execution and delivery of a fully effective and irrevocable separation agreement
and general release of claims against the Company and its subsidiaries and affiliates in a form satisfactory to the Company within sixty (60) days after your termination of employment. If you fail to comply with the requirements of the
preceding sentence, the Company will not have any obligation to provide the payments contemplated under this Section 6(c). Notwithstanding anything herein to the contrary, no payments under this Section 6(c) will be made until the first
regular Company payroll date that occurs following the expiration of the sixty (60) day period described above (the “Release Payment Date”), with all payments delayed pursuant to this sentence being paid on the Release Payment Date to
you in a lump sum, and any remaining payments due under this Section 6(c) being paid in accordance with the normal payment dates specified for them. 

  

	 	(d)	For purposes of this letter, “Cause” means (i) your conviction of a felony, your plea of guilty or “no contest” to a felony, or your confession of guilt to a felony, in each case whether or not
in connection with the performance of your duties to the Company, (ii) any act or omission by you which constitutes willful misconduct or negligence that results in loss, damage or injury to the Company or its prospects, including, but not
limited to (A) disloyalty, dishonesty or a breach of fiduciary duty to the Company or its shareholders, (B) theft, fraud, embezzlement or other illegal conduct, or (C) disregard of a rule or policy of the Company, (iii) your
failure, refusal or unwillingness to perform, to the reasonable satisfaction of the Board determined in good faith, any duty or responsibility assigned to you in connection with the performance of your duties hereunder, which failure of performance
continues for a period of more than seven (7) days after written notice thereof has been provided to you by the Board, such notice to set forth in reasonable detail the nature of such failure of performance, or (iv) the material breach by
you of any of the provisions of this letter, including specifically Exhibit A. 

  

	 	(e)	 For purposes of this letter, “Good Reason” means, in the context of your resignation from your
employment position with the Company, a resignation that occurs within thirty (30) days following: (i) a change in the principal location at which you provide services to the Company beyond fifty (50) miles from Cambridge, MA;
(ii) a reduction in your compensation or a material reduction in other benefits, except such a reduction in connection with a general reduction in compensation or other benefits of all senior executives of the Company; or (iii) a




  
 -3- 









	 	
material breach of this letter by the Company that has not been cured within ten (10) days after written notice thereof by you to the Company, which notice sets forth in reasonable detail
the nature of such breach. 

  

	 	(f)	In the event of your death or permanent disability (as defined below) while you are employed by the Company, your employment hereunder shall immediately and automatically terminate and the Company shall pay to you or
your personal representative or designated beneficiary or, if no beneficiary has been designated by you, to your estate, any earned and unpaid base salary, pro-rated through the date of your death or permanent
disability. For purposes of this letter, “permanent disability” shall mean your inability, due to physical or mental illness or disease, to perform the functions then performed by you for ninety (90) days during any twelve
(12) month period; provided that the foregoing definition shall not include a disability for which the Company is required to provide reasonable accommodation pursuant to the Americans with Disabilities Act or other similar statute or
regulation. 

  

	 	(g)	Notwithstanding anything in this Agreement to the contrary: 

  

	 	(i)	The parties agree that this Agreement will be interpreted to comply with or be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations and guidance
promulgated thereunder to the extent applicable (collectively “Section 409A”), and all provisions of this Agreement will be construed in a manner consistent with the requirements for avoiding taxes or penalties under
Section 409A. In no event whatsoever will the Company be liable for any additional tax, interest or penalties that may be imposed on you under Section 409A or any damages for failing to comply with Section 409A. 


 

	 	(ii)	 A termination of employment will not be deemed to have occurred for purposes of any provision of this Agreement
providing for the payment of any amounts or benefits upon or following a termination of employment that are considered “nonqualified deferred compensation” under Code Section 409A unless such termination is also a “separation
from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination”, “termination of employment”, or like terms will mean “separation from
service”. If you are deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment that is considered nonqualified deferred
compensation under Code Section 409A payable on account of a “separation from service,” such payment or benefit will be made or provided at the date which is the earlier of (A) the expiration of the six (6)-month period measured
from the date of your “separation from service”, and (B) the date of your death (as applicable, the “Delayed Payment Date”), and all payments and benefits delayed pursuant to this sentence (whether they would have otherwise
been payable in a single 



  
 -4- 









	 	
sum or in installments in the absence of such delay) will be paid or reimbursed on the Delayed Payment Date to you (or your estate) in a lump sum, and any remaining payments and benefits due
under Section 6(c) of this Agreement will be paid or provided in accordance with the normal payment dates specified for them. 

  

	 	(iii)	With regard to any provision in this Agreement that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Code Section 409A,
(i) the right to reimbursement or in-kind benefits will not be subject to liquidation or exchange for another benefit, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year will not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year,
provided that the foregoing clause (ii) will not be violated with regard to expenses reimbursed under any arrangement covered by Code Section 105(b) solely because such expenses are subject to a limit related to the period the arrangement
is in effect and (iii) such payments will be made on or before the last day of your taxable year following the taxable year in which the expense occurred. 

  

	 	(iv)	For purposes of Code Section 409A, your right to receive any installment payments pursuant to this Agreement will be treated as a right to receive a series of separate and distinct payments. Whenever a payment
under this Agreement may be paid within a specified period, the actual date of payment within the specified period will be within the sole discretion of the Company. 


 

	 	(h)	Payroll Deductions. All payments to you under this Agreement will be reduced by all applicable payroll deductions and withholdings. 


6.    General. 
  

	 	(a)	This letter, together with Exhibits A, will constitute our entire agreement as to your employment by the Company and will supersede any prior agreements or understandings, whether in writing or oral.


  

	 	(b)	This letter shall be governed by the law of the Commonwealth of Massachusetts. 

  

	 	(c)	The Company’s obligations under this letter are contingent upon approval of its terms by the Board and the board of managers of Solid GT. 


You may accept this offer of employment and the terms and conditions thereof by signing the enclosed additional copy of this letter, which
execution will evidence your agreement with the terms and conditions set forth herein and therein, and returning them to the Company.

 EXHIBIT A 

EMPLOYEE TERMS AND CONDITIONS 
 In
consideration and as a condition of my employment and/or continued employment by Solid Biosciences, LLC, a Delaware limited liability company (the “Company”), I hereby agree as follows: 

 

	1.	Nondisclosure. I shall not at any time, whether during or after my employment, regardless of the reason for my termination, reveal to any person or entity any Confidential Information except to employees of the
Company who need to know such Confidential Information for the purposes of their employment, or as otherwise authorized by the Company in writing. The term “Confidential Information” shall include, without limitation, any information and
derivative information, in whatever form or medium, including oral information, concerning the organization, business, finances or personnel of the Company or of any third party which the Company is under an obligation to keep confidential or that
is maintained by the Company as confidential. Such Confidential Information includes, but is not limited to, research and development activities performed by or on behalf of the Company, financial information about the Company or of any third party,
personnel information, information regarding the business activities or personnel actions of the Company, and any confidential information or documents of third parties, including, but not limited to, business plans, projects, and proposals.
Notwithstanding the foregoing, Confidential Information does not include information that: (a) is publicly known and generally available in the public domain other than in consequence of improper action by any person; or (b) was acquired
by me free and clear of any duty of confidentiality or restricted use and without improper action by the transferor of such information or any other person. I shall not use or attempt to use any Confidential Information except as may be required in
the ordinary course of performing my duties as an employee of the Company, and I shall not use any Confidential Information in any manner that may injure or cause loss or may be calculated to injure or cause loss to the Company, whether directly or
indirectly. 

 2.    Work-Made-for Hire. 

 

	 	a)	All right, title and interest in any and all writings, ideas, inventions, know-how, designs, improvements or other property created, adapted or improved by me (whether alone or in
conjunction with any other person) during my employment which relate in any way to the assets, business or operations of the Company, constituting copyrights, patents, trademarks, service marks and related rights or other forms of proprietary rights
or information (regardless of whether any such copyrights, patents, trademarks and service marks or other rights have or may be registered), and all material created during my employment that includes any of the foregoing (collectively,
“Covered Material”), are hereby assigned to, and shall be owned by, the Company, and to the extent that they include copyrightable subject matter, shall be deemed works made for hire for the Company within the meaning of the United States
Copyright Act of 1976 and for all other purposes. 


  
 -7- 









	 	b)	The Company shall have the right to apply for and obtain registrations in the United States Copyright Office and the United States Patent and Trademark Office, in its own or its designee’s name, of its rights in
any or all of the Covered Material. If for any reason the rights in any Covered Material are registered, or applied to be registered, in my name, I shall assign in writing such application or registration to the Company and hereby authorize and
appoint the Company its agent for the purpose of recording such assignment. 

  

	 	c)	Whenever the Company shall so request, whether during or after my employment, I shall execute, acknowledge and deliver all applications, assignments or other instruments; make or cause to be made all rightful oaths;
testify in all legal proceedings; communicate all known facts which relate to such works, copyrights, inventions, ideas, discoveries, designs and improvements; perform all lawful acts and otherwise render all such assistance as the Company may deem
necessary to protect the Company’s interest therein including any assistance which the Company shall deem necessary in connection with any proceeding or litigation involving the same. The Company shall reimburse me for all reasonable out-of-pocket costs, incurred by me in rendering any such assistance requested by the Company pursuant to this Section. 


 

	3.	Non-hire of Employees and Consultants. During my employment and the one year period following the termination of my employment, regardless of the reason for my termination,
I will not (except on the Company’s behalf), directly or indirectly, alone or as a consultant, partner, officer, director, employee, joint venturer, lender or stockholder of any entity, employ, hire, retain, attempt to employ, hire or retain,
or knowingly permit any company or business organization by which I am employed or which is directly or indirectly controlled by me to employ, hire or retain, any Company employee or consultant, or any such person whose employment or consultancy
with the Company has terminated within six months prior to or after my departure from the Company. 

  

	4.	Nonsolicitation of Employees and Consultants. During my employment and the one year period following the termination of my employment, regardless of the reason for my termination, I will not (except on the
Company’s behalf), directly or indirectly, alone or as a consultant, partner, officer, director, employee, joint venturer, lender or stockholder of any entity, in any manner seek to solicit or induce any Company employee or consultant, or any
such person whose employment or consultancy with the Company has terminated within six months prior to or after my departure from the Company, to leave his or her employment or consultancy with the Company, or assist in the recruitment or hiring of
any such person. 

  

	5.	Nondisparagement. I shall not at any time, whether during or after the termination of my employment, regardless of the reason for my termination, make to any person or entity disparaging, critical or otherwise
detrimental comments of a business or personal nature relating to the Company or its personnel. 


  
 -8- 









	6.	Company Property. I agree that during my employment I shall not make, use or permit to be used any Company Property otherwise than for the benefit of the Company. The term “Company Property” shall
include all Confidential Information; the Company’s records, files and data; all Company computers, cellular telephones, personal digital assistants, credit and/or calling cards, keys, access cards and the like; and all other documentation or
materials of any nature and in any form, whether written, printed, electronic or in digital format or otherwise, relating to any matter within the scope of the business of the Company or concerning any of its dealings or affairs and any other
Company property in my possession, custody or control. I further agree that I shall not, after the termination of my employment, regardless of the reason for my termination, use or permit others to use any such Company Property. I acknowledge and
agree that all Company Property shall be and remain the sole and exclusive property of the Company. Immediately upon the termination of my employment I shall deliver all Company Property in my possession, and all copies thereof, to the Company.


  

	7.	Term of Employment. I understand and agree that my employment with the Company is on an “at will” basis and that either the Company or I may terminate my employment at any time, for any or no reason, on
notice to the other party. 

 8.    Representations. 

 

	 	a.	I represent that my employment with the Company and my performance of all of these terms and conditions do not and will not breach any agreement to keep in confidence proprietary information acquired by me in confidence
or in trust prior to my Company employment, nor will it violate any nonsolicitation and/or noncompetition agreements entered into prior to my Company employment. I have not entered into, and I shall not enter into, any agreement either written or
oral in conflict herewith. 

  

	 	b.	I further agree that any breach of these terms and conditions by me will cause irreparable damage to the Company and that in the event of such breach the Company shall have, in addition to any and all remedies of law,
the right to an injunction, specific performance or other equitable relief to prevent the violation of my obligations hereunder. 

  

	9.	Waiver; Amendments. Any waiver by the Company of a breach of any provision of these terms and conditions shall not operate or be construed as a waiver of any subsequent breach of such provision or any other
provision hereof. In addition, any amendment to or modification of these terms and conditions or any waiver of any provision hereof must be in writing. 

  

	10.	 Severability. I agree that each provision and the subparts of each provision herein shall be treated as
separate and independent clauses, and the unenforceability of any one clause shall in no way impair the enforceability of any of the other clauses of these terms and conditions. Moreover, if one or more of the provisions contained in these terms and
conditions shall for any reason be held to be excessively broad as to scope, activity, term, subject or otherwise so as to be unenforceable at law, such provision or provisions shall




  
 -9- 









	 	
be construed by the appropriate judicial body by limiting or reducing it or them, so as to be enforceable to the maximum extent compatible with the applicable law as it shall then appear. I
hereby further agree that the language of all parts of these terms and conditions shall in all cases be construed as a whole according to its fair meaning and not strictly for or against either of the parties. 


 

	11.	Survival. These terms and conditions shall be effective as of the date entered below. My obligations under these terms and conditions shall survive the termination of my employment regardless of the reason for or
manner of such termination and shall be binding upon my heirs, executors, administrators and legal representatives. 

  

	12.	Assignment. The Company shall have the right to assign these terms and conditions to its successors and assigns, and all covenants and agreements hereunder shall inure to the benefit of and be enforceable by said
successors or assigns. I may not assign these terms and conditions. 

  

	13.	Governing Law. These terms and conditions shall be governed by and construed in accordance with the laws of the State of Delaware and shall in all respects be interpreted, enforced and governed under the internal
and domestic laws of Delaware, without giving effect to the principles of conflicts of laws of such state. The laws of the State of Delaware shall govern any claims or legal actions by one party against the other arising out of the relationship
between the parties contemplated herein (whether or not arising under these terms and conditions). 

 IN WITNESS HEREOF, I have executed these
terms and conditions as of the date first written below.
