Explanation of Responses:

1. On June 1, 2009, Reporting Person was granted 85,000 performance-based restricted stock units, each representing a contingent right to receive one share of Limelight Networks common stock at no cost. The actual award could have been as low as 0 shares or as high as 85,000 shares based upon the achievement of certain revenue and adjusted EBIT performance metrics during the performance period. Following the conclusion of the performance period, it was determined that the performance was achieved at a level that entitled Reporting Person to be eligible to receive 90.4% of the award, or 76,874 shares. On August 10, 2010, the first 1/3 of the award vested and converted into 25,624 shares.

2. The amount in this column previously reflected the entire June 1, 2010 award of 85,000 performance-based restricted stock units. It was determined that the performance was achieved at a level that entitled Reporting Person to be eligible to receive 90.4% of the award, or 76,874 shares. The amount currently in this column has been updated to reflect that 25,624 restricted stock units vested and were delivered to Reporting Person on August 10, 2010 and that 51,250 restricted stock units remain eligible to vest subject to service requirement.

3. The sale reported in this row represents restricted stock units that were withheld by the Company solely for the purpose of satisfying tax obligations arising upon the automatic vesting of 25,624 restricted stock units.
