The exchange is intended to further enhance the alignment between compensation and shareholder value creation. The time-based RSUs, which were scheduled to vest on January 1, 2008, were exchanged for RSUs that will vest, if at all, on January 15, 2008 based on the attainment of pre-determined performance goals involving the completion of 3G agreements having certain values and benefits to the Company. If less than 80% performance of the target goal is achieved, participants will receive no payout. If performance meets or exceeds 150% of the target goal, the payout will be three times the number of RSUs exchanged. The remaining 50% of the time-based vesting RSUs which were previously granted to the persons identified above under the Company's Long Term Compensation Program remain unchanged. William J. Merritt, Chief Executive Officer; Bruce Bernstein, General Patent Counsel; Richard J. Fagan, Chief Financial Officer; Mark Lemmo, Senior Business Development & Product Management Officer; William K.
