       On April&amp;#160;14, 2010, the Company acquired all of the
       outstanding stock of Insight Technology Incorporated, a
       manufacturer of mission critical night vision and
       electro-optical equipment, for a preliminary purchase price of
       $613&amp;#160;million. The purchase price was funded with cash on
       hand and is subject to adjustment based on the closing date
       actual net working capital, which has not been finalized. The
       final purchase price allocation is expected to be completed by
       the fourth quarter of 2010.

       On January&amp;#160;30, 2009, the Company acquired all of the
       outstanding stock of Chesapeake Sciences Corporation (CSC) for a
       purchase price of $91&amp;#160;million in cash, which included a
       $7&amp;#160;million net working capital adjustment and
       $4&amp;#160;million related to certain tax benefits acquired. The
       net working capital adjustment included $6&amp;#160;million for cash
       acquired. The acquisition was financed using cash on hand. CSC
       is a developer and manufacturer of anti-submarine warfare
       systems for use onboard submarines and surface ship combatants.
       Based on the final purchase price allocation, the amount of
       goodwill recognized was $56&amp;#160;million, which was assigned to
       the Electronic Systems reportable segment, and is not expected
       to be deductible for income tax purposes.
