Dear Joe:


 


Following our recent discussions,
I am very pleased to invite you to serve as Chairman of the Board of Directors (the “Board”) of Century Therapeutics,
Inc. (f/k/a Century Therapeutics, LLC, the “Company”), on the terms and subject to the conditions set forth below.


 


1.             Appointment.
Upon your acceptance of this letter, in connection with the conversion of the Company from a Delaware limited liability company to a
Delaware corporation (which is anticipated to occur on or before February 24, 2021) (the “Conversion”), your nomination
to serve as Chairman of the Board will be submitted to the other members of the Board for approval. In connection with your appointment,
you shall hold office until such time that your successor is duly elected and qualified, or until your earlier death, retirement, resignation
or removal from office. The terms and obligations under this letter agreement shall remain in full force and effect until your earlier
death, retirement, resignation or removal from the Board; provided that the obligations under Section 6 shall survive indefinitely.


 


2.             Duties.
As an independent director, you will be expected to attend the meetings of the Board and the Committees of the Board on which you serve,
as regularly or specially called. Board meetings are scheduled upon prior consultation with directors and are typically held in Philadelphia,
PA. You may attend and participate at each such meeting via teleconference, video conference or in person.


 


3.             Fiduciary Obligations; Governance: The Company is governed by Delaware law. The structure, practices and authority of the
Board, including matters relating to the size and composition of the Board, the election and removal of directors, requirements relating
to Board action and the appointment of executive officers, effective as of the Conversion, will be governed by the Company’s Amended
and Restated Certificate of Incorporation and Bylaws, as each may be amended from time to time (the “Organizational Documents”).


 


4.             Compensation.
As consideration for your service as a member of the Board, the Company will pay you the following compensation:


 







(a)          
Equity Award. Subject to the approval of the Board, upon the closing of an equity financing resulting in gross proceeds
to the Company of at least $155,000,000 (the “Series C Financing”), the Company will grant to you a one-time nonqualified
stock option exercisable for the purchase of 683,601 shares of the Company’s common stock, par value $0.0001


 






     


     


    

 


per share (the “Common
Stock”) (the “Option”), which, together with existing awards previously granted to you by the Company, brings
your equity ownership in the Company following the closing of the Series C Financing to 1% of the Company measured on a fully diluted
basis. The Option will: (i) be subject to the terms and conditions of the Century Therapeutics, Inc. 2018 Stock Option and Grant Plan
(as amended, restated or otherwise modified from time to time, the “Plan”) and the Non-Qualified Stock Option Agreement
by and between you and the Company (the “Award Agreement”), (ii) have an exercise price per share equal to the fair
market value per share of Common Stock on the date of the grant, as determined by the Board, and (iii) be subject to vesting requirements
such that 25% of the shares of Common Stock underlying the Option shall vest on the first anniversary of the date of grant, and thereafter,
the remaining 75% of the shares of Common Stock underlying the Option shall vest in 36 substantially equal monthly installments, in each
case if you continue to provide services to the Company as of the applicable vesting date; provided, however, that any then-unvested
portion of the Option shall automatically vest upon the closing of a Sale Event (as defined in the Plan) if you continue to provide services
to the Company through such event.


 


(b)          Annual
Retainer. Subject to approval by the Board, for so long as you continue to serve as a director of the Company, you shall be entitled
to receive an annual retainer of $50,000, payable on a quarterly basis. Such retainer shall be pro-rated for any partial year.


 


5.             Expenses. The Company will pay or reimburse the reasonable, authorized expenses incurred by you in the discharge of your
duties as a director, in accordance with the general practices and policies of the Company and upon the submission of appropriate documentation.

addition, the Company will also carry director and officer liability insurance and you will be a covered person under any such policy
