Explanation of Responses:

1. The original Form 4 has been amended for the purpose of reporting this transaction. The reporting person acquired these shares pursuant to the Transaction Agreement among Alliant Techsystems Inc. (renamed Orbital ATK, Inc.) ("Orbital ATK"), Vista Merger Sub Inc., Vista Outdoor Inc. (formerly known as Vista SpinCo Inc.) and Orbital Sciences Corporation ("Orbital") (the "Transaction Agreement"), pursuant to which each share of Orbital common stock was converted into 0.449 shares of Orbital ATK common stock and cash payable in lieu of fractional shares of Orbital ATK common stock. The reporting person had purchased his now-converted Orbital shares in 2003 and 2006 through a brokerage firm. The market value of Orbital ATK common stock was $63.94 per share based on the opening price per share of Orbital ATK common stock on the first day of trading following the Merger (as defined in the Transaction Agreement).

2. At the time of this reported transaction, 3,943 of these shares were subject to certain restrictions including possible forfeiture under Orbital ATK's (formerly Alliant Techsystems Inc.'s) 2005 Stock Incentive Plan. In addition, this total has been adjusted to include 182 shares in paper certificate form that the reporting person has owned since 2002 and were inadvertently not included in previous totals.
