(1) This amendment is being filed solely to (i) correct the number of restricted stock units that were subject to the transaction reported in Table I and (ii) add the grants of phantom stock units which were inadvertently omitted from the original Form 4 of the reporting person dated October 3, 2007.

The reporting person has elected to defer receipt of the stock awarded upon vesting of such units until April 30, 2016.
(3) Includes shares of common stock acquired as a result of the disbribution of issuer common stock in connection with Spin-Off.
(4) The phantom stock units are converted on a one for one basis and were granted by the issuer in connection with the Spin-Off in substitution of 8,527 NCR phantom stock units.
(5) The phantom stock units are to be settled in cash and/or common stock on April 30, 2015.
(6) The phantom stock units are converted on a one for one basis and were granted by the issuer in connection with the Spin-Off in substitution of 6,034 NCR phantom stock units.
(7) The phantom stock units are to be settled in cash and/or common stock on April 30, 2014.
(8) The phantom stock units are converted on a one for one basis and were granted by the issuer in connection with the Spin-Off in substitution of 5,080 NCR phantom stock units.
(9) The phantom stock units are to be settled in cash and/or common stock on April 30, 2013.
(10) The phantom stock units are converted on a one for one basis and were granted by the issuer in connection with the Spin-Off in substitution of 238 NCR phantom stock units.
