Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On December 21, 2011, the Art and Jayn Marshall Trust DTD 7/2/1973 (the "Art and Jayn Trust") received 31,000 shares from the Arthur Trust DTD 7/2/1973 (the "Arthur Trust"). Because the Reporting Person was a trustee of the Art and Jayn Trust, and not a trustee of the Arthur Trust, the transfer was a gift that should have been included in the Reporting Person's Form 4 filings.
(2) On February 2, 2012, the Art and Jayn Trust transferred 31,000 shares to the Jayn Marshall Family GST Exempt U/A DTD 7/29/73 (the "Jayn Marshall Trust"), of which the Reporting Person is also a trustee. No transactions have subsequently occurred that would effect the balance of securities reported in the Jayn Marshall Trust.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
