POWER OF ATTORNEY

	I, Dalvir S. Gill, hereby authorize and designate each of David B.
Kaysen, Scott Kellen, W. Morgan Burns, Joshua L. Colburn and Justina A.
Roberts, signing singly, as my true and lawful attorney-in-fact to:

(1) execute for and on my behalf, in my capacity as an officer and/or
director of Sun BioPharma, Inc. (the "Company"), Form ID or Forms 3, 4 and 5
in accordance with Section 16(a) of the Securities Exchange Act of 1934 (the
"Exchange Act") and the rules and regulations promulgated thereunder and
other forms or reports on my behalf as may be required to be filed in
connection with my ownership, acquisition, or disposition of securities of
the Company, including Form 144;

(2) do and perform any and all acts for and on my behalf which may be
necessary or desirable to complete and execute any such Form ID or Forms
3, 4 or 5 and timely file such form with the 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 to my
benefit, in my best interest, or legally required of me, it being understood
that the statements executed by such attorney-in-fact on my behalf 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.

I hereby further grant 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 I 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.  I
hereby acknowledge that the foregoing attorneys-in-fact, in serving in such
capacity at my request, are not assuming, nor is the Company assuming, any of
my responsibilities to comply with Section 16 of the Exchange Act.

This Power of Attorney shall remain in full force and effect until I am no
longer required to file Form ID or Forms 3, 4 and 5 with respect to my holdings
of and transactions in securities issued by the Company, unless earlier revoked
by me in a signed writing delivered to the foregoing attorneys-in-fact.
Notwithstanding the foregoing, if any such attorney-in-fact hereafter ceases to
be at least one of the following:  (i) a partner or employee of Faegre Baker
Daniels LLP or (ii) an officer or employee of Sun BioPharma, Inc., then this
Power of Attorney shall be automatically revoked solely as to such individual,
immediately upon such cessation, without any further action on my part.

I hereby revoke all previous Powers of Attorney that have been granted by me in
connection with my reporting obligations under Section 16 of the Exchange Act
with respect to my holdings of and transactions in securities issued by the
Company.

IN WITNESS WHEREOF, I have caused this Power of Attorney to be duly executed as
of this 13th day of December 2016.
