K. Asirifi and Kathy L. Uttley, signing singly, the undersigned's true and
lawful attorney-in-fact and agent to:

1) execute for, in the name of and on behalf of the undersigned Forms 3, 4 and
5 with respect to the securities of the Company beneficially owned by the
undersigned in accordance with Section 16(a) of the Securities Exchange
Act of 1934, as amended (the "1934 Act") and the rules and regulations
thereunder and Form 144 with respect to the securities of the Company
beneficially owned by the undersigned in accordance with Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act");

2) do and perform any and all acts for, in the name of and on behalf of the
undersigned which may be necessary or desirable to complete and execute any
such Form 3, 4 or 5 or such Form 144, complete and execute any amendment or
amendments thereto, and timely file any such form (and any such amendment or
amendments) 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 each 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 and resubstitution, 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 above-named attorneys-in-fact, in serving in such

issued by the Company, unless earlier revoked by the undersigned in a signed
writing delivered to the above-named attorneys-in-fact.  I hereby revoke all
previous Powers of Attorney that have been granted by me in connection with
my reporting obligations under the 1934 Act or the Securities Act with respect
to my holdings of and transactions in securities issued by the Company.

	IN WITNESS WHEREOF, the undersigned has caused this Power
of Attorney to be executed as of this 5th day of May, 2016.
