Dear Changgeng:

and you (the Second Amendment, and, together with the Offer Letter and the First Amendment, the Amended Offer Letter).

Notwithstanding anything to the contrary in the Amended Offer Letter, Curis and you hereby agree that, as of the date hereof, in consideration for the grant to you of an Option to purchase 51,000 shares of common stock of Curis (the

Plan) and will be subject to the terms and conditions of the Plan and a stock option agreement by and between you and the Company in the form previously furnished to you.

Curis and you hereby agree that the aforementioned reduction in salary shall not constitute Good Reason as defined in the Amended Offer Letter and that in connection with any termination of employment you

employee within the meaning of Section 409A(a)(2)(B)(ii) of the Internal Revenue Code and the regulations thereunder, as determined by the Company in accordance with its procedures, by which determination the Executive hereby agrees that
he is bound, then any payments to be paid or provided to the Executive under this Amendment that constitute nonqualified deferred compensation within the meaning of Section 409A of the Code shall be delayed by a period of six
(6) months and all payments that would have been made to the Executive during such six (6) month period shall be made in a lump sum in the seventh (7th) month following the date of termination.

benefits are to be paid or commence occurs in the calendar year following the year of the Executives date of termination, the severance payments shall be paid or commence no earlier than January 1 of such subsequent calendar year.
