*	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)	The Deferred Stock Units ("DSUs") are fully vested on grant, but settlement is deferred until the earlier of Wes Robinson and/or John Lagemann's termination of board service (as the case may be) and a change in control of the Issuer.
(2)	In accordance with the Issuer's 2016 Omnibus Equity Incentive Plan, the closing price per share of the Issuer's common stock on May 17, 2016 was used to determine the number of DSUs to be issued.
(3)	Represents DSUs awarded on behalf of Messrs. Robinson and Lagemann in connection with their service as directors of the Issuer. As employees/director designees of the Reporting Person (Deere & Company) and as previously disclosed by the Issuer, Messrs. Robinson and Lagemann have assigned to the Reporting Person all rights to compensation otherwise receivable by them as directors of the Issuer. The DSUs are fully vested. A corresponding number of shares of common stock will be issued at such time as Messrs. Robinson and/or Lagemann no longer serve as directors.
