Explanation of Responses:

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 grant of phantom stock units which was inadvertently omitted from the original Form 4 of the reporting person dated October 3, 2007. The original Form 4 was timely filed and correct in all other respects.

2. These restricted stock units were granted by the issuer in substitution of 2,791 shares of restricted stock units of NCR Corporation ("NCR"), at a ratio of 1 to 1, in connection with the spin-off of the issuer by NCR (the "Spin-Off") pursuant to which, on September 30, 2007, NCR distributed one share of the issuer's common stock for every one share of NCR common stock held as of the close of business on September 14, 2007. The reporting person has elected to defer receipt of the stock awarded upon vesting of such units until the termination of his service as a director.

3. Includes shares of common stock acquired as a result of the distribution 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 11,628 NCR phantom stock units.

5. The phantom stock units are to be settled in cash and/or common stock upon the reporting person's termination of service as a director.
