Each of these plans provides for the grant of stock options and
other stock- based awards to employees, officers, directors,
consultants and advisors of the Company and its subsidiaries.
Stock option grants have an exercise price equal to the fair
market value of the Company’s common stock on the date of
grant and generally have a
<font style="white-space: nowrap">10-year</font>
term. The fair value of stock option grants is recognized, net
of an estimated forfeiture rate, using an accelerated method
over the vesting period of the options, which is generally four
years.

In February 2009, the Board of Directors adopted the 2009 Plan,
which provided for the grant of stock options, restricted stock
awards, stock appreciation rights and other stock-based awards
to any person who (a) was not previously an employee or
director of the Company or (b) was commencing employment
with the Company following a bona fide period of non-employment
by the Company, as an inducement material to the individual
entering into employment with the Company. The purpose of the
2009 Plan was to advance the interests of the Company’s
stockholders by enhancing the Company’s ability to attract,
retain and motivate persons who were expected to make important
contributions to the Company and providing such persons with
equity ownership opportunities that were intended to better
align their interests with those of the Company’s
stockholders. The 2009 Plan was administered by the Compensation
Committee of the Board of Directors, which had the authority to
grant awards under the 2009 Plan. Under the 2009 Plan, the
Company was authorized to issue up to 1,500,000 shares of
common stock, subject to adjustment in the event of stock splits
and other similar events, pursuant to awards granted under the
2009 Plan. Options granted under the 2009 Plan generally have a
<font style="white-space: nowrap">10-year</font> term
and vest 25% one year after grant and thereafter in equal
monthly installments over a three-year period. The 2009 Plan
terminated on May 31, 2010. As of December 31, 2010,
an aggregate of 316,967 options had been issued and remained
outstanding under the 2009 Plan.

In April 1998, the Company adopted the 1998 Plan, which provided
for the grant of stock options, restricted stock and other
stock-based awards to employees, officers, directors,
consultants, and advisors of the Company and its subsidiaries,
including any individuals who have accepted an offer of
employment. The 1998 Plan terminated in April 2008. Under the
1998 Plan, the Board of Directors had authority to determine the
term of each option, the option price, the number of shares for
which each option is granted and the rate at which each option
becomes exercisable. The 1998 Plan provided that
6,118,259 shares of common stock could be issued pursuant
to awards under the 1998 Plan. Shares awarded under the 1998
Plan that were subsequently cancelled were available to be
granted again under the 1998 Plan. During 1999, the Board of
Directors amended all then-outstanding options to allow holders
to exercise the options prior to vesting, provided that the
shares of common stock issued upon exercise of the option would
be subject to transfer restrictions and vesting provisions that
allowed the Company to repurchase unvested shares at the
exercise price. The Board of Directors delegated its authority
under the 1998 Plan to the Compensation Committee, which
administered the 1998 Plan, including granting options and other
awards under the 1998 Plan. In addition, pursuant to the terms
of the 1998 Plan, the Board of Directors delegated to the
Company’s chief executive officer limited authority to
grant stock options to employees without further action by the
Board of Directors or the Compensation Committee. Options
granted under the 1998 Plan generally vest in increments over
four years and have a ten-year term. The Company ceased making
grants under the 1998 Plan following adoption of an amendment to
the 2004 Plan at its annual stockholders’ meeting on
May 25, 2006.

Aggregate intrinsic value is the sum of the amounts by which the
quoted market price of the Company’s common stock exceeded
the exercise price of the options at December 31, 2010, for
those options for which the quoted market price was in excess of
the exercise price. The weighted-average grant date fair value
of options granted during the years ended December 31,
2010, 2009 and 2008 was $4.27, $4.69, and $8.08, respectively.
The total intrinsic value of options exercised during the years
ended December 31, 2010, 2009 and 2008 was
$1.0 million, $0.1 million, and $1.2 million,
respectively.

The fair value of each option element of the Company’s 2000
Employee Stock Purchase Plan and 2010 Employee Stock Purchase
Plan (the 2000 ESPP and the 2010 ESPP) is estimated on the date

six-month offering period for the 2000 ESPP. The risk-free
