WFII Wireless Facilities (MM)

Johnson & Perkinson (�J&P�), hereby amends its prior notice regarding the filing of this suit. J&P�s prior notice incorrectly stated that if you bought Wireless Facilities securities between March 29, 2001 and March 12, 2007, you may, not later than sixty (60) days from March 16, 2007, move the court to serve as lead plaintiff. The correct date for moving for lead plaintiff is 60 days from March 19, 2007. While other law firms have published advertisements referencing the filing of a suit on behalf of such purchasers, J&P, along with its local counsel, Scott & Scott, LLP, assembled and filed the only suit which has been brought on behalf of the plaintiff and the proposed class of purchasers of securities of Wireless Facilities, Inc. (NASDAQ: WFII) (�WFI� or �Company�) during the period March 29, 2001 to March 12, 2007 inclusive (the �Class Period�).

Members of the firm have prosecuted complex class actions on behalf of plaintiffs in the areas of securities and consumer fraud since 1985. Based in South Burlington, Vermont, the firm has prosecuted leading actions on behalf of defrauded investors against numerous public companies resulting in the recovery of many millions of dollars and has been singled out for its excellence by various courts. The firm is litigating, or recently resolved litigation, as lead or co-lead counsel in securities class actions against Xerox, Priceline, i2, Allaire, and Xchange, and serves on the Executive Committee in the Global Crossing case.
