       The undersigned hereby constitutes and appoints each of Tracy Hanson,
Justin Judd, Jillian Forusz, Jonathan Vaas, Allison Blais, and Lucy Jensen
signing individually, the undersigned's true and lawful attorney-in-fact to:
       (1)    execute for and on behalf of the undersigned, in the undersigned's
capacity as a Section 16 officer of Adobe Systems Incorporated (the "Company"), Form
ID, and Forms 3, 4 and 5 (collectively, "Forms") in accordance with Section 16(a) of
the Securities Exchange Act of 1934 and the rules thereunder;
       (2)    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 Forms and timely
file such form with the United States Securities and Exchange Commission and any stock
exchange or similar authority; and
       (3)    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 Securities Exchange Act of 1934.
       The undersigned agrees that each such attorney-in-fact may rely on information furnished
by the undersigned. The undersigned also agrees to indemnify and hold harmless the Company and
each attorney-in-fact against any losses, claims, damages or liabilities (or actions in these
respects) that arise as a result of 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.
       This Power of Attorney supersedes any power of attorney previously executed by the
undersigned regarding the purposes outlined herein ("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 with respect to the undersigned's holding of and transaction in
securities issued by the Company, unless earlier revoked by the undersigned in a signed writing
delivered to the foregoing attorneys-in-fact.
       IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be executed as of
January 24, 2018.
