<i>Stock-based Compensation Plans.</i>  Effective
April 29, 2008, the Company adopted the 2008 Long Term
Performance Plan (2008 LTPP) and the 2008 Directors Stock
Incentive Plan (2008 DSIP). As a result, no subsequent awards in
respect of shares of L-3 Holdings common stock have been or will
be issued under the Company’s 1997 Stock Option Plan, the
1998 Directors Stock Option Plan and the 1999 Long Term
Performance Plan (Prior Plans).

Awards under the 2008 LTPP may be granted to any officer or
employee of the Company or any of its subsidiaries, or to any
other individual who provides services to or on behalf of the
Company or any of its subsidiaries. Awards under the 2008 LTPP
may be in the form of stock options, stock appreciation rights,
restricted stock and other stock-based awards (including
restricted stock units and performance units).

Under the terms of the 2008 LTPP, (i) the maximum number of
shares of L-3 Holdings’ common stock that may be issued
pursuant to “incentive” stock option awards (i.e.,
stock options granted in accordance with Section 422 of the
U.S. Internal Revenue Code of 1986, as amended) is 3,000,000,
(ii) the maximum number of shares of L-3 Holdings’
common stock that may be issued (or paid in cash by reference to
such shares) pursuant to all awards granted during a calendar
year to any individual participant is 500,000 and (iv) the
maximum number of shares of L-3 Holdings’ common stock that
may be issued (or paid in cash by reference to such shares) to
any participant over the life of the 2008 LTPP with respect to
performance-based awards may not exceed 5% of L-3 Holdings’
total outstanding shares of common stock.

On April 27, 2010, the stockholders of L-3 Holdings
approved an amendment to the 2008 LTPP that increased the number
of shares authorized for issuance under the 2008 LTPP to
approximately 12.2 million shares, except that each
share of L-3 Holdings common stock issued under a “full
value” award (i.e., awards other than stock options or
stock appreciation rights) granted on or after March 1,
2010 will be counted as 2.6 shares for purposes of this
share limit. At December 31, 2010, 8.4 million shares
of L-3 Holdings’ common stock remained available for future
awards under the 2008 LTPP.

Awards under the 2008 DSIP may be granted only to non-employee
directors of the Company. Awards under the 2008 DSIP may be in
the form of stock options, restricted stock, restricted stock
units and minimum ownership stock. At December 31, 2010,
the number of shares of L-3 Holding’s common stock
authorized for grant under the 2008 DSIP was 300,000, of which,
272,218 shares were still available for awards. The 2008 LTPP
and the 2008 DSIP are collectively referred to as the 2008 Plans.

To date, awards under the 2008 Plans and Prior Plans
(collectively, the Plans) have been in the form of L-3
Holdings’ restricted stock, restricted stock units,
performance units and options to purchase L-3 Holdings’
common stock. The Company adopted the Plans in order to provide
incentives to directors, officers, employees and other
individuals providing services to or on behalf of the Company
and its subsidiaries. The Company believes that its stock-based
compensation awards encourage high levels of performance by
individuals who contribute to the success of the Company and
enable the Company to attract, retain and reward talented and
experienced individuals. This is accomplished by providing
eligible individuals with an opportunity to obtain or increase a
proprietary interest in the Company
<font style="white-space: nowrap">and/or</font> by
providing eligible individuals with additional incentives to
join or remain with the Company. The Plans serve to better align
the interests of management and its employees with those of the
Company’s shareholders.

<i>Stock Options.</i> The exercise price of stock options
that may be granted under the 2008 Plans may not be less than
the fair market value of L-3 Holdings’ common stock on the
date of grant. Options expire after 10 years from the date
of grant and vest ratably over a three year period on the annual
anniversary of the date of grant. All unvested options are
subject to forfeiture upon termination of employment (subject to
customary exceptions for death or disability). Compensation
expense for stock option awards was $12 million
($8 million after income taxes) for the year ended
December 31, 2010, $16 million ($10 million after
income taxes) for the year ended December 31, 2009, and
$17 million ($10 million after income taxes) for the
year ended December 31, 2008. All of the stock option
awards issued under the Plans are non-qualified stock options
for U.S. income tax regulations. The table below presents a
summary of the Company’s stock option activity as of
December 31, 2010 and changes during the year then ended.

<i>Restricted Stock Units.</i> The Company awards
restricted stock units that automatically convert into shares of
L-3 Holdings’ common stock upon vesting (in the case of
awards granted to employees) or upon the date on which the
recipient ceases to be a director (in the case of awards granted
to directors). These awards are subject to forfeiture until
certain restrictions have lapsed, including a three year cliff
vesting period for employees and a one year cliff vesting period
for directors, in each case starting on the date of grant. The
weighted average grant date fair value of each restricted stock
units awarded was $90.23, $74.02 and $98.18 for the years ended
December 31, 2010, 2009 and 2008, respectively. The grant
date fair value of the restricted stock unit awards is based on
L-3 Holdings’ closing stock price at the date of grant, and
will generally be recognized as compensation expense on a
straight-line basis over the vesting period. However, for
employees who attain retirement eligibility status prior to the
end of the three year cliff vesting period, and who have
provided at least one year of service after the date of grant,
compensation expense is recognized over the shorter period from
the date of grant to the retirement eligibility date. Retirement
eligible employees are those employees that have
attained the age of 65 and have completed at least five years of
service (which service must be continuous through the date of
termination except for a single break in service that does not
exceed one year in length).

As of December 31, 2010, total unrecognized compensation
costs related to nonvested restricted stock unit awards were

<i>Performance Units.</i> The Company’s Long-Term
Incentive Program (LTIP) is a multi-year performance program
under which each participant receives a target award of
performance units, with each unit having a value at the time of
grant equal to a share of L-3 Holdings’ common stock. The
number of units ultimately earned can range from zero to 200% of
the target award. The final value of each award will vary based
upon (1) the level of performance achieved by the Company
over the associated performance period in relation to
pre-determined performance goals established by the Compensation
Committee of the Board of Directors of L-3 Holdings and
(2) the closing price of L-3 Holdings’ common stock at
the end of the performance period. Units issued under the
program are payable in either cash or shares of
<font style="white-space: nowrap">L-3 Holdings’</font>
common stock as determined at the time of grant by the
Compensation Committee.

In 2010, 2009, and 2008, the Company awarded performance units
with a weighted average grant date fair value per unit of
$105.14, $87.18, and $103.10, respectively. Of these units,
(1) the final value of half of the units is contingent upon
the compound annual growth rate in L-3’s diluted earnings
per share (the EPS Element) and (2) the final value of half
of the units is contingent upon L-3’s total stockholder
return relative to a peer group of companies (the TSR Element).
The performance period for units awarded during 2010 is for the
three-year period ending December 31, 2012. The performance
period for units awarded during 2009 and 2008 begins on the
first day of the Company’s fiscal third quarter of the
applicable grant year and ends on the December 31 that is two
and a half years later. Units related to the EPS Element are
payable in shares of L-3 Holdings’ common stock, while
units related to the TSR Element are payable in cash based on
the closing price of L-3 Holdings’ common stock at the end
of the performance period. The total compensation expense
recognized for all LTIP awards for the years ended
December 31, 2010, 2009, and 2008 was $3 million
($2 million after income taxes), $9 million
($5 million after income taxes), and $4 million
($2 million after income taxes), respectively. As of
December 31, 2010, total unrecognized compensation costs
related to the performance units were $4 million
($3 million after income taxes) and are expected to be
recognized over a weighted average remaining period of
1.6 years.

<i>Employee Stock Purchase Plan.</i> Effective July 1,
2009, the Company adopted the 2009 Employee Stock Purchase Plan
(2009 ESPP). As a result, no subsequent options to purchase
shares of L-3 Holdings’ common stock have been or will be
granted under the Company’s prior employee stock purchase
plan (2001 ESPP).

The general terms of the 2009 ESPP are substantially identical
to those of the 2001 ESPP. Under the 2009 ESPP, eligible
employees are offered options to purchase shares of L-3
Holdings’ common stock at the end of each six-month
offering period at 85% of fair market value (or 95% of fair
market value for offering periods beginning on or after
January 1, 2011) based on the average of the highest
and lowest sales prices for the stock on the purchase date.
Eligible employees generally include all employees of the
Company and each subsidiary or affiliate of the Company that has
been designated to participate in the 2009 ESPP. Offering
periods begin on the first trading day in January and July of
each calendar year and end on the last trading day in June and
December of each calendar year. Share purchases are funded
through payroll deductions of up to 10% of an employee’s
eligible compensation for each payroll period, or $21,250 each
calendar year.
