issued to employees in February 2012. Excludes purchase rights that accrue under the ESPP. Purchase rights
under the ESPP are considered equity compensation for accounting purposes; however, the number of shares
to be purchased is indeterminable until the time shares are actually issued, as automatic employee
contributions may be terminated before the end of an offering period and, due to the look-back pricing
feature, the purchase price and corresponding number of shares to be purchased is unknown.
(c) Excludes performance share units and restricted stock units because those awards do not have exercise prices
associated with them. Also excludes purchase rights under the ESPP for the reasons described in (b) above.
(d) The shares remaining available include 8,938,274 shares under our 2009 Stock Incentive Plan and
668,986 shares under our ESPP. No additional shares may be issued under any of the other plans approved by
stockholders, other than on account of awards already outstanding.
(e) Includes our 2000 Broad-Based Employee Plan. No awards under the Broad-Based Plan are held by, or may
be granted to, any of our directors or executive officers. The Broad-Based Plan allows for the granting of
equity awards on such terms and conditions as the MD&C Committee may decide; provided, that the exercise
price of options may not be less than 100% of the fair market value of the stock on the date of grant, and all
options expire no later than ten years from the date of grant.
(f) Includes options exercisable for shares of Common Stock.
