       On January&amp;#160;30, 2009, the Company acquired all of the
       outstanding stock of CSC for a preliminary purchase price of
       $92&amp;#160;million, consisting of: (1)&amp;#160;$87&amp;#160;million in
       cash, including a $7&amp;#160;million net working capital
       adjustment, of which $6&amp;#160;million was for cash acquired, and
       (2)&amp;#160;a purchase price payable of $5&amp;#160;million related to
       certain tax benefits acquired. CSC is a developer and
       manufacturer of anti-submarine warfare systems for use onboard
       submarines and surface ship combatants. Based on the preliminary
       purchase price allocation, the amount of goodwill recognized was
       $57&amp;#160;million, which was assigned to the Specialized Products
       reportable segment, and is not expected to be deductible for
       income tax purposes. The final purchase price allocation is
       expected to be completed during the
   fourth quarter of 2009, and will be based on final appraisals
       and other analyses of fair values for acquired assets and
       assumed liabilities. The Company does not expect any of the
       differences between the preliminary and final purchase price
       allocations to have a material impact on its results of
       operations and financial position. The acquisition was financed
       with cash on hand.
   &lt;/div&gt;

   &lt;/div&gt;

       During the
       &lt;font style="white-space: nowrap"&gt;year-to-date&lt;/font&gt;
       period ended September&amp;#160;25, 2009, the Company completed the
       purchase price allocations for G.A. International (GAI) and
       International Resources Group, Ltd. (IRG), subject to the
       finalization of the purchase price for GAI. The purchase price
       for GAI is subject to additional consideration not to exceed
       $1&amp;#160;million that is contingent upon GAI&amp;#8217;s
       post-acquisition financial performance through July&amp;#160;25,
       2011. Any additional consideration paid that is contingent upon
       post-acquisition performance will be accounted for as goodwill.
       The final purchase price allocations for these business
       acquisitions compared to the preliminary purchase price
       allocations did not have a material impact on the Company&amp;#8217;s
       results of operations or financial position.

       On October&amp;#160;8, 2008, the Company divested its 85% ownership
       interest in Medical Education Technologies, Inc. (METI), which
       was within the Specialized Products reportable segment. The sale
       resulted in a fourth quarter 2008 after-tax gain of
       $20&amp;#160;million (pre-tax gain of $33&amp;#160;million). The gain
       was excluded from income from continuing operations for the 2008
       fourth quarter in accordance with U.S.&amp;#160;GAAP for impairment
       or disposal of long-lived assets (contained in FASB ASC Topic
       360, &lt;i&gt;Property, Plant, and Equipment &lt;/i&gt;and FASB ASC Topic
       205, &lt;i&gt;Presentation of Financial Statements&lt;/i&gt;)&lt;i&gt;.&lt;/i&gt;The
       revenues, operating results and net assets of METI for all
       periods presented were not material and, therefore, are not
       presented as discontinued operations. METI generated
       $17&amp;#160;million of sales and $2&amp;#160;million of operating
       income for the quarter ended September&amp;#160;26, 2008,
       $47&amp;#160;million of sales and $4&amp;#160;million of operating
       income for the
       &lt;font style="white-space: nowrap"&gt;year-to-date&lt;/font&gt;
       period ended September&amp;#160;26, 2008, and $48&amp;#160;million of
       sales and $4&amp;#160;million of operating income for the year ended
       December&amp;#160;31, 2008.
   &lt;/div&gt;

       On May&amp;#160;9, 2008, the Company sold the Electron Technologies
       Passive Microwave Devices (PMD) product line, which was within
       the Specialized Products reportable segment. The sale resulted
       in a second quarter 2008 after-tax gain of approximately
       $7&amp;#160;million (pre-tax gain of $12&amp;#160;million), which was
       recorded as a reduction of cost
   of sales for products in the Unaudited Condensed Consolidated
       Statement of Operations. The net proceeds from the sale are
       included in investing activities on the Unaudited Condensed
       Consolidated Statement of Cash Flows. The PMD product line
       generated $8&amp;#160;million of sales for both the
       &lt;font style="white-space: nowrap"&gt;year-to-date&lt;/font&gt;
       period ended September&amp;#160;26, 2008 and the year ended
       December&amp;#160;31, 2008.
