Class Action Suit Filed against Vonage Holdings Corporation by the Law Firm of Lovell Stewart Halebian LLP

NEW YORK--(BUSINESS WIRE)--June 19, 2006--Lovell Stewart Halebian LLP hereby gives notice that it has filed a class action lawsuit in the United States District Court for the District of New Jersey on behalf of purchasers of the common stock of Vonage Holdings Corporation ("Vonage" or the "Company") who purchased or otherwise acquired Vonage common stock pursuant or traceable to the Company's May 23, 2006 Initial Public Offering (the "IPO"). If you would like to discuss this action, receive a copy of the complaint, or have any questions about this notice or your rights or interests with respect to these matters, please contact Lovell Stewart Halebian LLP (Christopher Lovell, Esq. or Imtiaz A. Siddiqui, Esq.) at [phone] or via email at [e-mail].

The Complaint alleges that Vonage, the underwriters of its IPO, and certain of its officers and directors violated federal securities laws. Specifically, the Complaint alleges that the Company failed to disclose and misrepresented the following material adverse facts which were known to defendants or recklessly disregarded by them: (1) that Vonage's Voice over Internet Protocol ("VoIP") technology platform was unsuitable for transmitting facsimile communications; (2) that certain of its products are incompatible with the products and services of other VoIP providers; (3) that the Company did not adequately inform investors of the history of certain officers and directors of the Company; and (4) that Vonage customers who participated in the Directed Share Program (the "Program") were not informed of several key facts relating to the Program.

Plaintiff seeks to recover damages on behalf of class members and is represented by the law firm of Lovell Stewart Halebian LLP.

Lovell Stewart Halebian LLP has represented investors in numerous financial class actions and obtained, what were at the time, the largest class action recoveries under three separate federal statutes. If you are a member of the class described above, you may, not later than August 1, 2006, move the Court to serve as lead plaintiff of the class, if you should so choose. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member's claim is typical of other class members, and that the class member will adequately represent the class. Under certain circumstances, one or more class members may together serve as "lead plaintiff." Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. You may retain Lovell Stewart Halebian LLP, or other counsel of your choice, to serve as your counsel in this action.
