Reference is made to (i) that certain base call option transaction confirmation, dated as of November 8, 2017, by and between Sarepta Therapeutics, Inc. (“Counterparty”) and JPMorgan Chase Bank, National Association, London Branch (“Dealer”) (the “Base Capped Call Confirmation”) and (ii) that certain additional call option transaction confirmation, dated as of November 9, 2017, between Counterparty and Dealer (the “Additional Capped Call Confirmation” and, together with the Base Capped Call Confirmation, the “Capped Call Confirmations”). Capitalized terms used but not defined herein have the meaning ascribed to them in the Capped Call Confirmations.

Notwithstanding anything to the contrary in the Capped Call Confirmations, or in any notice delivered by Counterparty to Dealer prior to the date hereof, Counterparty hereby requests Dealer, and by signing below Dealer hereby agrees, that the Settlement Method for the Options will be Cash Settlement.

Except as otherwise set forth herein, the Capped Call Confirmations shall remain unchanged and in full force and effect. From and after the date hereof, any reference to the Capped Call Confirmations shall be a reference to the Capped Call Confirmations as supplemented hereby. This supplement may not be modified, amended or supplemented, except in a written instrument signed by Counterparty and Dealer.

Each of Dealer and Counterparty reaffirms and repeats the representations and warranties in Section 3(a) of the Agreement. Counterparty also represents that it is not, as of the date hereof, in possession of any material non‑public information with respect to the Counterparty or the Shares.
