On March 5, 2010, the United States District Court for the Northern District of California (the “Court”) issued an order (the “Preliminary Order”) granting preliminary approval of the settlement of the consolidated stockholder derivative litigation captioned In re VeriSign, Inc. Derivative Litigation, Master File No. 4:06-cv-04165-PJH (the “Litigation”).

Pursuant to the Stipulation and Agreement of Settlement of Litigation (“Stipulation”), attached hereto as Exhibit 99.1, the Company, the plaintiffs, and certain of the Company’s former and current officers and directors have entered into a settlement of the Litigation. The settlement is subject to final approval by the Court, which has scheduled a hearing on June 2, 2010.

Under the terms and conditions of the Stipulation, the Company will make certain corporate governance changes and the Company will pay an agreed amount of $750,000 to plaintiffs’ counsel for attorneys’ fees and expenses, all subject to final Court approval. Upon final approval of the Stipulation, the settling defendants will be dismissed with prejudice from the Litigation. Plaintiffs in the cases captioned Port Authority of Allegheny County v.
