What Is The Option Exchange? How the Option Exchange Works Making Your Decision Using the Option Exchange Website Questions You have until 4 p.m. Pacific Time on September 14, 2011 to make elections online Overview Leap’s long-standing practice has been to grant equity awards from time to time to eligible employees as a substantial component of their at-risk compensation in order to motivate them to achieve key business objectives. Like many telecommunications companies, the price of our common stock has declined over the past several years. As a result, many of our employees hold stock options with exercise prices that are higher than the recent trading prices of Leap common stock. We continue to believe that equity awards are an important component of our compensation program. However, we believe that many employees view their existing stock options as having little or no retentive or incentive value due to the significant difference between the exercise prices and the current market price of Leap common stock. In order to restore the intended retentive and motivational value of our employees’ stock options, we have designed the Option Exchange to give employees the opportunity to exchange eligible existing stock options for a lesser number of replacement stock options with a lower exercise price. In order to achieve this goal without increasing overhang (the total number of shares underlying outstanding stock options as a percentage of Leap’s total shares of common stock), we also designed the Option Exchange to return surrendered options to the authorized pool of shares that may be granted in the future.
