Explanation of Responses:

1. Represents the vesting (at 112% of target) of Performance-Based Restricted Stock Units (PSUs) granted on March 16, 2015 for the 2017 performance period. As a result of the achievement of 112%, which was above target, the Company increased the number of shares granted to the individual by 500 shares, or the above-target amount, to account for such achievement.Performance for this award during the award's 2017 performance period was measured based on the Issuer's total shareholder return (TSR) compared to pre-established relative TSR goals, based on the TSR of the NASDAQ Telecommunications Index, that were set by the Compensation Committee of the Issuer's Board of Directors.

2. The PSUs have fully vested and accordingly have no expiration date.

3. PAYMENT OF TAX LIABILITY BY DELIVERING SECURITIES TO THE COMPANY INCIDENT TO THE VESTING OF A SECURITY.
