     KNOW ALL BY THESE PRESENTS, that the undersigned hereby constitutes and
appoints Christopher Garabedian, Sandesh Mahatme, David Tyronne Howton and
Anthony Martignetti, and their respective successors, and each of them his true
and lawful attorney-in-fact and agent with full power of substitution, signing
singly, for his and in his name, place and stead, in any and all capacities, to:

  1. prepare, execute in the undersigned's name and on the undersigned's behalf,
     and submit to the U.S. Securities and Exchange Commission (the "SEC") a Form ID,
     including amendments thereto, and any other documents necessary or appropriate
     to obtain codes and passwords enabling the undersigned to make electronic
     filings with the SEC of reports required by Section 16(a) of the Securities
     Exchange Act of 1934 (as amended, the "Exchange Act") or any rule or
     regulation of the SEC;

  2. complete and execute for and on behalf of the undersigned, in the undersigned's
     capacity as an officer and/or director of Sarepta Therapeutics, Inc.
     (the "Company") and/or 10% holder of the Company's capital stock, Forms 3,
     4, 5 and Form ID, any other forms, and any amendments thereto in accordance
     with Section 16(a) of the Exchange Act and the rules and regulations thereunder;

   3. do and perform any and all acts for and on behalf of the undersigned which
      may be necessary or desirable to complete and execute any such Form 3, 4, 5
      or Form ID, or any other forms,  complete and execute any amendment or
      amendments thereto, and timely file such form with the SEC and any stock
      exchange or similar authority; and

  4. take any other action of any type whatsoever in connection with the foregoing
     which, in the opinion of such attorney-in-fact, may be of benefit to, in the
     best interest of, or legally required by, the undersigned, it being
     understood that the documents executed by such attorney-in-fact on behalf of
     the undersigned pursuant to this Power of Attorney shall be in such form and
     shall contain such terms and conditions as such attorney-in-fact may approve
     in such attorney-in-fact's discretion.

     The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this power of attorney and the rights and powers herein granted.
The undersigned acknowledges that the foregoing attorneys-in-fact, in serving
in such capacity at the request of the undersigned, are not assuming, nor is the
Company assuming, any of the undersigned's responsibilities to comply with
Section 16 of the Exchange Act.

     The undersigned agrees that each such attorney-in-fact herein may rely
entirely on information furnished orally or in writing by the undersigned to such
attorney-in-fact.  The undersigned also agrees to indemnify and hold harmless the
Company and each such attorney-in-fact against any losses, claims, damages or
liabilities (or actions in these respects) that arise out of or are based upon
any untrue statements or omission of necessary facts in the information provided
by the undersigned to such attorney-in fact for purposes of executing,
acknowledging, delivering or filing Forms 3, 4 or 5, Form ID or any other form
(including amendments thereto) and agrees to reimburse the Company and such
attorney-in-fact for any legal or other expenses reasonably incurred in connection
with investigating or defending against any such loss, claim, damage, liability
or action.

     This Power of Attorney supersedes any power of attorney previously executed
by the undersigned regarding the purposes outlined in the first paragraph hereof
("Prior Powers of Attorney"), and the authority of the attorneys-in-fact named in
any Prior Powers of Attorney is hereby revoked.

     This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier (a) revoked by the undersigned in a signed writing delivered to
the foregoing attorneys-in-fact or (b) superseded by a new power of attorney
regarding the purposes outlined in the first paragraph hereof dated as of a
later date.

     IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 19th day of April, 2013.
