       A substantial majority of the Company&amp;#8217;s revenues are
       generated from providing products and services under legally
       binding agreements or contracts with U.S.&amp;#160;Government and
       foreign government customers. U.S.&amp;#160;Government contracts are
       subject to extensive legal and regulatory requirements, and from
       time to time, agencies of the U.S.&amp;#160;Government investigate
       whether such contracts were and are being conducted in
       accordance with these requirements. The Company is currently
       cooperating with the U.S.&amp;#160;Government on several
       investigations, including those specified below, from which
       civil, criminal or administrative proceedings have or could
       result and give rise to fines, penalties, compensatory and
       treble damages, restitution
       &lt;font style="white-space: nowrap"&gt;and/or&lt;/font&gt;
       forfeitures. The Company does not currently anticipate that any
       of these investigations will have a material adverse effect,
       individually or in the aggregate, on its consolidated financial
       position, results of operations or cash flows. However, under
       U.S.&amp;#160;Government regulations, an indictment of the Company
       by a federal grand jury, or an administrative finding against
       the Company as to its present responsibility to be a
       U.S.&amp;#160;Government contractor or subcontractor, could result
       in the Company being suspended for a period of time from
       eligibility for awards of new government contracts or task
       orders or in a loss of export privileges. A conviction, or an
       administrative finding against the Company that satisfies the
       requisite level of seriousness, could result in debarment from
       contracting with the federal government for a specified term. In
       addition, all of the Company&amp;#8217;s U.S.&amp;#160;Government
       contracts: (1)&amp;#160;are subject to audit and various pricing and
       cost controls, (2)&amp;#160;include standard provisions for
       termination for the convenience of the U.S.&amp;#160;Government or
       for default, and (3)&amp;#160;are subject to cancellation if funds
       for contracts become unavailable. Foreign government contracts
       generally include comparable provisions relating to terminations
       for convenience and default, as well as other procurement
       clauses relevant to the foreign government.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;

       The Company is also subject to litigation, proceedings, claims
       or assessments and various contingent liabilities incidental to
       its businesses, including those specified below. Furthermore, in
       connection with certain business acquisitions, the Company has
       assumed some or all claims against, and liabilities of, the
       acquired business, including both asserted and unasserted claims
       and liabilities.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 2%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       In accordance with the accounting standard for contingencies,
       the Company records a liability when management believes that it
       is both probable that a liability has been incurred and the
       Company can reasonably estimate the amount of the loss.
       Generally, the loss is recorded at the amount the Company
       expects to resolve the liability. The estimated amounts of
       liabilities recorded for pending and threatened litigation are
       disclosed in Note&amp;#160;8. Amounts recoverable from insurance
       contracts or third parties are recorded as assets when deemed
       probable. At April&amp;#160;1, 2011, the Company did not record any
       amounts for recoveries from insurance contracts or third parties
       in connection with the amount of liabilities recorded for
       pending and threatened litigation. Legal defense costs are
       expensed as incurred. The Company believes it has recorded
       adequate provisions for its litigation matters. The Company
       reviews these provisions quarterly and adjusts these provisions
       to reflect the impact of negotiations, settlements, rulings,
       advice of legal counsel and other information and events
       pertaining to a particular matter. While it is reasonably
       possible that an unfavorable outcome may occur in one or more of
       the following matters, unless otherwise stated below, the
       Company believes that it is not probable that a loss has been
       incurred in any of these matters. An estimate of loss or range
       of loss is disclosed for a particular litigation matter when
       such amount or amounts can be reasonably estimated and no loss
       has been accrued. The Company believes that any damage amounts
       claimed in the specific matters discussed below do not
       constitute reasonable estimates of loss. Although the Company
       believes that it has valid defenses with respect to legal
       matters and investigations pending against it, the results of
       litigation can be difficult to predict, particularly those
       involving jury trials. Accordingly, our current judgment as to
       the likelihood of our loss (or our current estimate as to the
       potential range of loss, if applicable) with respect to any
       particular litigation matter may turn out to be wrong.
       Therefore, it is possible that the financial position, results
       of operations or cash flows of the Company could be materially
       adversely affected in any particular period by the unfavorable
       resolution of one or more of these or other contingencies.
   &lt;/div&gt;

       &lt;i&gt;Kalitta Air.&lt;/i&gt;&amp;#160;On January&amp;#160;31, 1997, a predecessor
       of Kalitta Air filed a lawsuit in the U.S.&amp;#160;District Court
       for the Northern District of California (the trial court)
       asserting, among other things, negligence and negligent
       misrepresentation against Central Texas Airborne Systems, Inc.
       (CTAS), a predecessor to L-3 Integrated Systems (L-3 IS), in
       connection with work performed by a predecessor to CTAS to
       convert two Boeing 747 aircraft from passenger configuration to
       cargo freighters. The work was performed using Supplemental Type
       Certificates (STCs) issued in 1988 by the Federal Aviation
       Administration (FAA). In 1996, following completion
   of the work, the FAA issued an airworthiness directive with
       respect to the STCs that effectively grounded the aircraft. On
       August&amp;#160;11, 2000, the trial court granted CTAS&amp;#8217; motion
       for summary judgment as to negligence, dismissing that claim. In
       January 2001, after a ruling by the trial court that excluded
       certain evidence from trial, a jury rendered a unanimous defense
       verdict in favor of CTAS on the negligent misrepresentation
       claim. On December&amp;#160;10, 2002, the U.S.&amp;#160;Court of Appeals
       for the Ninth Circuit (the Court of Appeals) reversed the trial
       court&amp;#8217;s decisions as to summary judgment and the exclusion
       of evidence, and remanded the case for a new trial on both the
       negligence and negligent misrepresentation claims. The retrial
       ended on March&amp;#160;2, 2005 with a deadlocked jury and mistrial.
       On July&amp;#160;22, 2005, the trial court granted CTAS&amp;#8217; motion
       for judgment as a matter of law as to negligence, dismissing
       that claim, and denied CTAS&amp;#8217; motion for judgment as a
       matter of law as to negligent misrepresentation. On
       October&amp;#160;8, 2008, the Court of Appeals reversed the trial
       court&amp;#8217;s dismissal of the negligence claim and affirmed the
       trial court&amp;#8217;s ruling as to the negligent misrepresentation
       claim. As a result, the case was remanded to the trial court to
       reconsider the negligence claim and for further proceedings on
       the negligent misrepresentation claim. The trial court held a
       new hearing on CTAS&amp;#8217; motion to dismiss the negligence claim
       on April&amp;#160;30, 2009, after which it determined to take the
       matter under advisement. The case is currently scheduled to go
       to a third jury trial on October&amp;#160;31, 2011. The parties have
       participated in court-ordered mediations from time to time, and
       may participate in future court-ordered mediations prior to
       trial, but to date such mediations have not resulted in a
       mutually acceptable resolution of this matter. In connection
       with these mediations, Kalitta Air has claimed it may seek
       damages at the third trial of between $430&amp;#160;million and
       $900&amp;#160;million, including between $200&amp;#160;million and
       $240&amp;#160;million of pre-judgment interest. CTAS&amp;#8217; insurance
       carrier has accepted defense of this matter and has retained
       counsel, subject to a reservation of rights by the insurer to
       dispute its obligations under the applicable insurance policies
       in the event of a finding against L-3. The Company believes that
       it has meritorious defenses to the claims asserted and the
       damages sought and intends to defend itself vigorously.
   &lt;/div&gt;

       &lt;i&gt;CyTerra Government Investigation.&lt;/i&gt;&amp;#160;Since November
       2006, CyTerra has been served with civil and Grand Jury
       subpoenas by the DoD Office of the Inspector General and the DoJ
       and has been asked to facilitate employee interviews. The
       Company is cooperating fully with the U.S.&amp;#160;Government. The
       Company believes that it is entitled to indemnification with
       respect to this matter, and has made a claim against a
       $15&amp;#160;million escrow fund established in connection with the
       Company&amp;#8217;s acquisition of CyTerra in March 2006.
   &lt;/div&gt;

       &lt;i&gt;Bashkirian Airways.&lt;/i&gt;&amp;#160;On July&amp;#160;1, 2004, lawsuits
       were filed on behalf of the estates of 31 Russian children in
       the state courts of Washington, Arizona, California, Florida,
       New York and New Jersey against Honeywell, Honeywell TCAS,
       Thales USA, Thales France, the Company and Aviation
       Communications&amp;#160;&amp;#038; Surveillance Systems (ACSS), which is
       a joint venture of L-3 and Thales. The suits relate to the crash
       over southern Germany of Bashkirian Airways Tupelov TU 154M
       aircraft and a DHL Boeing 757 cargo aircraft. On-board the
       Tupelov aircraft were 9 crew members and 60 passengers,
       including 45 children. The Boeing aircraft carried a crew of
       two. Both aircraft were equipped with Honeywell/ACSS Model 2000,
       Change 7 Traffic Collision and Avoidance Systems (TCAS). Sensing
       the other aircraft, the on-board DHL TCAS instructed the DHL
       pilot to descend, and the Tupelov on-board TCAS instructed the
       Tupelov pilot to climb. However, the Swiss air traffic
       controller ordered the Tupelov pilot to descend. The Tupelov
       pilot disregarded the on-board TCAS and put the Tupelov aircraft
       into a descent striking the DHL aircraft in midair at
       approximately 35,000&amp;#160;feet. All crew and passengers of both
       planes were lost. Investigations by the National Transportation
       Safety Board after the crash revealed that both TCAS units were
       performing as designed. The suits allege negligence and strict
       product liability based upon the design of the units and the
       training provided to resolve conflicting commands and seek
       approximately $315&amp;#160;million in damages, including
       $150&amp;#160;million in punitive damages. The Company&amp;#8217;s
       insurers have accepted defense of this matter and have retained
       counsel. The matters were consolidated in the U.S.&amp;#160;District
       Court for the District of New Jersey, which has dismissed the
       actions on the basis of forum non conveniens. The plaintiffs
       re-filed a complaint on April&amp;#160;23, 2007 with the Barcelona
       Court&amp;#8217;s Registry in Spain. On March&amp;#160;9, 2010, the court
       ruled in favor of the plaintiffs and entered judgment against
       ACSS in the amount of approximately $6.7&amp;#160;million, all of
       which represented compensatory damages. The Company believes
       that the verdict and the damages awarded are inconsistent with
       the law and evidence presented. Accordingly, ACSS filed an
       appeal of this ruling on April&amp;#160;27, 2010. The plaintiffs
       also filed an appeal of this ruling on the same date.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 2%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       &lt;i&gt;Gol Airlines.&lt;/i&gt;&amp;#160;A complaint was filed on
       November&amp;#160;7, 2006 in the U.S.&amp;#160;District Court for the
       Eastern District of New York against ExcelAire, Joseph Lepore,
       Jan Paul Paladino, and Honeywell. On October&amp;#160;23, 2007, an
       amended complaint was filed to include Lockheed, Raytheon,
       Amazon Technologies and ACSS. The complaints relate to the
       September&amp;#160;29, 2006 airplane crash over Brazil of a Boeing
       &lt;font style="white-space: nowrap"&gt;737-800&lt;/font&gt;
       operated by GOL Linhas Aereas Inteligentes, S.A. and an Embraer
       600 business jet operated by ExcelAire. The complaints allege
       that ACSS designed the TCAS on the ExcelAire jet, and assert
       claims of negligence, strict products liability and
   breach of warranty against ACSS based on the design of the TCAS
       and the instructions provided for its use. The complaints seek
       unspecified monetary damages, including punitive damages. The
       Company&amp;#8217;s insurers have accepted defense of this matter and
       have retained counsel. On July&amp;#160;2, 2008, the District Court
       dismissed the actions on the basis of forum non conveniens on
       the grounds that Brazil was the location of the accident and is
       more convenient for witnesses and document availability. On
       December&amp;#160;2, 2009, the U.S.&amp;#160;Court of Appeals for the
       Second Circuit upheld this decision. Twelve of the plaintiffs
       re-filed their complaints in the Lower Civil Court in the
       Judicial District of Peixoto de Azevedo in Brazil on
       July&amp;#160;3, 2009, but withdrew their complaints in July 2010
       without prejudice to their right to re-file them against ACSS.
       An additional four plaintiffs re-filed their complaints in the
       Lower Civil Court in Rio de Janiero before the expiration of the
       statute of limitations. ACSS has not been served in any of these
       actions. While the statute of limitations has expired and would
       bar any additional plaintiffs (beyond the 16 noted above) from
       re-filing claims directly against ACSS, it would not bar GOL
       from filing a future suit against ACSS based on litigation
       claims being pursued by the original plaintiffs against GOL in
       connection with this matter.
   &lt;/div&gt;
