10b5-1 Trading Plans
The following executive officers have entered into trading plans intended to comply with the guidelines specified in Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (Rule 10b5-1): Aristotle N. Balogh, Executive Vice President, Chief Technology Officer; Albert E. Clement, Chief Financial Officer; John M. Donovan, Executive Vice President, Global Sales and Consulting Services; and Mark D. McLaughlin, Executive Vice President, Products, Marketing and Customer Care. Other VeriSign executive officers (as well as VeriSign employees) may adopt Rule 10b5-1 trading plans from time to time. These plans generally provide for the exercise of stock options and the subsequent sale of the acquired shares on the open market and the sale of shares that were acquired upon vesting of restricted stock units, subject to specified limitations and minimum price thresholds. Under these plans, the executive officers do not control the specific timing of any option exercise or sale. Rule 10b5-1 permits corporate officers and directors to adopt written, pre-arranged stock trading plans when they are not in possession of material, non-public information.
