4. Protection Period.

• Exception to Double Trigger: If the consideration to be received by stockholders of the Company in connection with a Change-in-Control consists of substantially all cash, then 100% of all unvested and outstanding Equity Awards granted to participant prior to the Change-in-Control shall have their vesting and exercisability accelerated in full immediately prior to the Change-in-Control regardless of whether there is a Termination Upon Change-in-Control.

6. Severance Benefits. The following severance benefits shall be provided to the participant, subject to the participant’s signing VeriSign’s General Release Agreement waiving all claims against VeriSign upon the termination of the participant’s employment with VeriSign:

6.1 Cash Severance.

• Pro rata target bonus for year of termination of employment

• Lump sum payment equal to applicable multiple of sum of salary plus Bonus. Applicable multiple is 2X for CEO and 1X for all other participants. “X” refers to the salary plus Bonus. The “Bonus” is equal to the average of bonuses earned for the 3 prior fiscal years (or, if fewer, number of full fiscal years the participant was employed by VeriSign before the CIC, or the target bonus in the fiscal year of the termination if the participant was not eligible to receive a bonus from the Company during any of the prior 3 fiscal years).

• Payment of the amounts listed above in this Section 6.1 shall be made within 60 days of the date on which the Double Trigger Events have both occurred, except that such payments are subject to a 6 month delay if required by Internal Revenue Code Section 409A deferred compensation rules.

6.2 Other Severance Benefits

• Continuation of health benefits for the participant and eligible dependents for the number of years equal to the severance multiple (e.g., for two years for the CEO and for one year for all other participants), provided that such coverage of health benefits will cease if the participant becomes eligible for comparable benefits from a new employer. The period of time of continued health benefits is subject to being shortened if required by 409A rules.

7. Acceleration of Vesting Upon Double Trigger. In the event both of the Double Trigger Events occur, the participant shall receive acceleration of vesting of 100% of all unvested stock options and restricted stock units, effective immediately upon the occurrence of the second triggering event; provided, however, in circumstances where the consideration to be received by stockholders of the Company in connection with a Change-in-Control consists of substantially all cash, then the participant shall receive acceleration of vesting of 100% of all unvested stock options and restricted stock units in full effective immediately prior to the occurrence of the first triggering event (i.e., the Change-in-Control).

8. Confidentiality. The participant will be perpetually obligated to maintain the confidentiality of all VeriSign confidential information.

9. Noncompete. The participant will not compete with VeriSign for at least 12 months from his/her employment termination date.

10. Nonsolicitation. The employee will not solicit any VeriSign employees for at least 12 months from his/her employment termination date.

11. Arbitration. All disputes arising under the Agreement shall be settled by binding arbitration in California pursuant to the commercial arbitration rules of the American Arbitration Association.

12. Legal Fees. VeriSign shall reimburse the participant for all reasonable legal fees and expenses that he/she incurs in connection with pursuing or defending itself in connection with any dispute that may arise under the Agreement unless the participant does not substantially prevail in such dispute.

4

13. Amending The Agreement. The Board may amend the Agreement at any time, provided that any amendment adverse to a participant is not effective if a CIC occurs within one year after such amendment.

14. Termination of Agreement.

• To terminate the Agreement at the end of the then current term the Board must terminate the Agreement before the last 90 days of the then current term, otherwise the Agreement will not be terminated until the end of the subsequent term.

• A termination of the Agreement will not be effective if the CIC occurs within one year of such termination.

15. Federal Excise Tax Under Section 280G And Parachute Payments. If the amounts payable to the participant under the CIC Agreement qualifies as a parachute payment under Section 4999 of the Internal Revenue Code of 1986, as amended, and if the participant would consequently be subject to U.S. federal excise tax, then the executive’s termination benefits under the CIC Agreement will be payable, at the participant’s election, either in full or in such less amounts as would result in the participant’s receipt on an after-tax basis of the greatest amount of termination and other benefits after taking into account the applicable federal, state, and local income taxes and the excise tax imposed by Section 4999.
