CLASS ACTION COMPLAINT

JURY TRIAL DEMANDED

Plaintiff, individually and on behalf of all other persons similarly situated, by plaintiff' s

undersigned attorneys, alleges the following based upon personal knowledge as to plaintiff and

plaintiffs own acts, and upon information and belief as to all other matters, based on, inter alia,

the investigation conducted by and through plaintiff's attorneys, including a review of the

defendants' press releases, Securities and Exchange Commission ("SEC") filings by Vonage

Holdings Corporation ("Vonage" or the "Company") and media reports about the Company .

Plaintiff believes that substantial evidentiary support will exist for the allegations set forth herein

after a reasonable opportunity for discovery .

NATURE OF THE ACTION AND OVERVIEW

I . This is a federal class action on behalf of purchasers of the publicly traded

common stock of Vonage who purchased or otherwise acquired Vonage common stock pursuant

or traceable to the Company's May 23, 2006 Initial Public Offering (the "IPO" or the

"Offering"), seeking to pursue remedies under the Securities Act of 1933 (the "Securities Act") .

This claim is also being brought on behalf of Vonage customers who purchased or otherwise

acquired Vonage common stock through the Vonage Directed Share Program (the "Subclass") .

2. Vonage is a leading provider of broadband telephone services with over 1 .6

million subscriber lines as of April 1, 2006 .

3. The complaint alleges that, in connection with the Company's IPO, defendant s

failed to disclose that: ( 1) Vonage's technology platform experienced problems carrying

telephone data over the networks of certain internet service providers ; (2) Vonage's voice-over-

Internet protocol ("VoIP") technology did not properly allow facsimile transmissions ; (3) the

Company's management team's problematic history, including the fact that Tyco's ADT

Security division took $600 million in charges for accounting improp rieties while defendant

Michael Snyder was President of the division ; and (4) with respect to customers that opened

brokerage accounts and participated in Vonage 's Directed Share Program, such individuals were

not adequately informed regarding their obligations to purchase allocated shares , specifically,

that they were obligated to purchase allocated shares before they received notice that their

conditional offers had been accepted , and were led to believe that the IPO would take place later

than May 23, 2006 .

2

4. Immediately following the IPO, shares of Vonage plunged from the offering pric e

of $17.00 per share to close, on May 24, 2006, at $14 .85 per share, a loss of $2.15, or 12.6

percent, on concerns about the Company's ability to compete in the market place .

5 . Following these concerns, shares of Vonage continued to fall on news that the

Company's Directed Share Program was plagued by serious technical and logistical issues . In

the seven days after the 1PO, shares of Vonage declined over 30 percent .

SUBSTANTIVE ALLEGATIONSBackground

26 . Vonage is a leading provider of broadband telephone services with over 1 . 6

million subscriber lines as of April 1, 2006. The Company's award-winning technology enable s

anyone to make and receive phone calls with a touch tone telephone almost anywhere a

broadband Internet connection is available .

27 . Prior to its IPO, Vonage was a company that used its innovations into broadban d

telephone technology to generate near-term subscriber growth. However, the Company' s

elevated marketing costs and build-out expenses resulted in a mammoth deficit and failure t o

achieve profitability .

28 . As a result of the Company's high deficit and lack of profitability, and, amon g

other things, to reassure the investment community regarding its future growth plans, in it s

Prospectus, the Company stated:

For the period from our inception through March 31, 2006, ouraccumulated deficit was $467 .4 million . Our quarterly net losses

generally have increased each quarter from our inception throughthe quarter ended March 31, 2006, for which our net loss was$85 .2 million . Initially, our net losses were driven principally bystart-up costs and the costs of developing our technology. Morerecently, our net losses have been driven principally by marketingexpense, which was $88 .3 million for the three months endedMarch 31, 2006 . In order to grow our revenue and customer base,we have chosen to increase our marketing expendituressignificantly . We are pursuing growth, rather than profitability, inthe near term to capitalize on the current expansion of thebroadband and VoIP markets and enhance the future value of ourcompany . . . . We intend to continue to increase our marketingexpense, and we may continue to generate losses for the

6

foreseeable future . . .

29. Additionally, and with respect to the Company' s tenuous financial situation and

overall business model, various market commentators and analysts made the following critica l

statements at or around the time of the IPO :

Reuters, May 24, 2006

Vonage has acknowledged it may never be profitable and isviewed with skepticism by many analysts , who cite the growingcompetition it faces in providing voice-over-Internet protocol(VoIP) services. "It's very hard to see what their competitiveadvantage is," said Richard Greenfield , an analyst at Pali Research ."We basically believed , pre-IPO , that the price should be $10 orless . "

TheStreet.com, May 24, 2006

"Vonage is a ride-along service" using other companies'broadband connections to deliver calls, says one telecom investorwho is not buying the initial offering . "There is no sustainableadvantage as cable rolls out VoIP." . . .Indeed, Vonage's appeal toinvestors has been waning as more players rush to offer VoIPservices . Between low-cost calling plans from cable companiesand telcos, and the fast-growing appeal of free phone service fromoutfits like eBay's Skype, Vonage faces a formidable cast ofchallengers .

FORTUNE Magazine, May 24, 2006

Because Vonage's service rides on the broadband connectionscontrolled by cable or phone operators, it is somewhat limited inthe kinds of new services it can roll out . The cable operators, forexample, have been offering faster speeds over the cable modem

connection for an extra monthly fee . Vonage wouldn't be able tooffer that kind of premium service to its subscribers because itdoesn't control the pipeline to the customer . . . .And as for sellingother services, such as cable-television or wireless phone service,sure Vonage could resell another providers' offer, but reselling is apretty low margin business .

FORBES .com, May 24, 200 6

Vonage specializes in voice-over-Internet Protocol technology,which makes it possible to receive and send phone calls through anInternet connection. Eventually, the pricing for such technology

7

will drop to nil, [Todd Rothemeier, an analyst at SoleilSecurities/Sur Terre Research] says, as competition forces a price

war. "[Vonage] will have to radically change their businessmodel," he says .

The IPO

30. On February 8, 2006, Vonage filed its initial Form S-1 Registration Statemen t

with the SEC . The Company's Form S-1 stated that Vonage's IPO sought to raise up to $25 0

million .

31 . Also on February 8, 2006, Vonage announced that the Company had entered int o

an agreement with defendant Snyder. The Company reported that defendant Snyder woul d

replace defendant Citron as Vonage's Chief Executive Officer .

32 . From February 8, 2006 through May 23, 2006, Vonage amended the Company' s

Form S-1 on eight separate occasions on the following dates : April 7, 2006; April 12, 2006 ;

April 26, 2006 ; April 28, 2006; May 8, 2006 ; May 22, 2006 ; and two separate amendments on

May 23, 2006 .

33 . On May 23, 2006, the Company and the Underwriter Defendants set the price o f

the Vonage IPO shares at $17 .00 per share .

34. Also on May 23, 2006, the SEC declared that Vonage's Registration Statemen t

for the Offering was effective . Vonage and the Underwriter Defendants sold shares to Vonag e

customer investors that same day.

Materially False and Misleading StatementsMade In the Registration Statement or Prospectu s

a) Misstatements and Omissions Concerning Vonage's Services and Product s

35 . With respect to the risks related to the Company's service and products, th e

Company, in its Prospectus, stated :

Flaws in our technology and systems could cause delays or

8

interruptions of service, damage our reputation, cause us to losecustomers and limit our growth .

Although we have designed our service network to reduce the

possibility of disruptions or other outages, our service may bedisrupted by problems with our technology and systems, such asmalfunctions in our software or other facilities and overloading of

our network . Our customers have experienced interruptions in thepast and may experience interruptions in the future as a result of

these types of problems . Interruptions have in the past and may in

the future cause us to lose customers and offer substantial customercredits, which could adversely affect our revenue and profitability.For example, during 2005 our service was significantly impaired

on two separate occasions . In March 2005, a problem during a

software upgrade to our call processing system caused most of ourcustomers to experience intermittent service for several hours. In

August 2005, one of our third-party carriers experienced an outageof approximately 90 seconds, which caused a failure in some ofour gateways. As a result, during a period of several hours,approximately two out of three outbound calls from our customersto the public switched telephone network experienced an "allcircuits busy" condition. We have since had other outages thataffected smaller groups of customers at various times . In addition,because our systems and our customers' ability to use our servicesare Intern et-dependant, our services may be subject to "hackerattacks" from the Internet, which could have a significant impacton our systems and services . If service interruptions adverselyaffect the perceived reliability of our service, we may havedifficulty attracting and retaining customers and our brandreputation and growth may suffer.

Our ability to provide our service is dependent upon third-partyfacilities and equipment, the failure of which could cause delays orinterruptions of our service, damage our reputation, cause us tolose customers and limit our growth .

Our success depends on our ability to provide quality and reliable

service, which is in part dependent upon the proper functioning offacilities and equipment owned and operated by third parties andis, therefore, beyond our control . Unlike traditional wirelinetelephone service or wireless service, our service requires ourcustomers to have an operative broadband Internet connection andan electrical power supply, which are provided by the customer'sInternet service provider and electric utility company, respectively,and not by us . The quality of some broadband Internet connectionsmay be too poor for customers to use our services properly . Inaddition, if there is any interruption to a customer's broadband

9

Internet service or electrical power supply, that customer will beunable to make or receive calls, including emergency calls, usingour service. We also outsource several of our network functions tothird-party providers . For example, we outsource the maintenanceof our regional data connection points, which are the facilities atwhich our network interconnects with the public switchedtelephone network. If our third-party service providers fail tomaintain these facilities properly, or fail to respond quickly toproblems, our customers may experience service interruptions .Our customers have experienced such interruptions in the past andwill experience interruptions in the future. In addition, our new E-911 service is currently dependent upon several third-partyproviders . Interruptions in service from these vendors could causefailures in our customers' access to E-911 services . Interruptionsin our service caused by third-party facilities have in the pastcaused and may in the future cause us to lose customers, or cause

us to offer substantial customer credits, which could adverselyaffect our revenue and profitability. If interruptions adverselyaffect the perceived reliability of our service, we may havedifficulty attracting new customers and our brand, reputation andgrowth will be negatively impacted .

36. With respect to Vonage's facsimile and other services, the Company, in it s

Prospectus, stated :

We also offer a number of premium services for an additional fee,such as toll free numbers, fax numbers and virtual phone numbers .

Subscriber lines [as reported] include, as of a particular date, allsubscriber lines from which a customer can make an outboundtelephone call on that date . Our subscriber lines include fax lines,SoftPhones and WiFi phones but do not include our virtual phonenumbers or toll free numbers, which only allow inbound telephonecalls to customers .

We derive most of our telephony services revenue from monthlysubscription fees that we charge our customers under our serviceplans. We also offer residential fax service, virtual phonenumbers, toll free numbers and other services, for each of whichwe charge an additional monthly fee . One business fax line isincluded with each of our two small office and home office plans,but we charge monthly fees for additional business fax lines .

10

- Residential Fax Service . We offer 250 minutes of outgoing faxservice within the United States, Puerto Rico and Canada on adedicated fax line for $9.99 per month, plus unlimited incomingfaxes, with customers charged a per minute fee of 3 .9 centsthereafter .

- Business Fax Service. We offer 500 minutes of outgoing faxservice within the United States, Puerto Rico and Canada on adedicated fax line plus unlimited incoming faxes, with customerscharged a per minute fee of 3 .9 cents thereafter. One business faxline is included in each of our business calling plans. We offeradditional business fax lines for a monthly fee in the United Statesof $9.99 per line .

b) Misstatements Concerning Defendant Snyder

37. With respect to defendant Snyder's previous employment history, the Company ,

in its Prospectus, stated only that defendant Snyder had been employed as President of ADT

Security Services , Inc., a subsidiary of Tyco International Ltd. from 1997 to February 2006.

c) Misstatements Concerning Vonage's Directed Share Progra m

38. With respect how the share price was determined, the Company, in its Prospectus ,

stated:

The initial public offering price for the shares was determined bynegotiation between us and Citigroup Global Markets Inc .,Deutsche Bank Securities Inc . and UBS Securities LLC. Amongthe factors considered in determining the initial public offeringprice were our record of operations, our current financialcondition, our future prospects, the markets in which we operate,the economic conditions in and future prospects for the industry inwhich we compete, our management, and currently prevailinggeneral conditions in the equity securities markets, includingcurrent market valuations of publicly traded companies consideredcomparable to our company . The prices at which the shares willsell in the public market after this offering may be lower, however,than the initial public offering price. Furthermore, an activetrading market in our common stock may not develop or continueafter this offering .

39 . Additionally, and with respect to the Directed Share Program, the Company, in it s

11

Prospectus, stated that the underwriters would "reserve up to 13 .5% and 1 .5% of the common

stock offered in this prospectus for sale of our certain of our customers and other persons relate d

to us, respectively, at the initial public offering price . "

40. The Company, in its Prospectus, also stated :

In connection with the Directed Share Programs, we have agreedto indemnify the underwriters against certain liabilities, includingthose that may be caused by the failure of Directed Share Program

participants to pay for and accept delivery of the common stockwhich had been allocated to them or were subject to a properlyconfirmed agreement to purchase . As a result, our expected netproceeds could be reduced if Directed Share Program participantsfail to pay for an accept delivery of the common stock which hadbeen allocated to them or were subject to a properly confirmedagreement to purchase and, as a result, we must indemnify theunderwriters for such failure.

41 . However, rather than properly qualifying Vonage customers, defendants allowed

Vonage customers to receive up to 5,000 shares of Vonage stock based upon an e-mail reques t

and the opening of an account with either Smith Barney, Deutsche Bank Alex. Brown or UBS

Financial . The IPO failed to contain any request for the customer's financial information, ta x

status, investment objectives, or other information considered to be reasonable beyond

confirmation that the Vonage customer's telephone account was in good standing, opened prio r

to December 15, 2005, and that the customer was a U .S. citizen.

42 . Subclass members that participated in the Directed Share Program were instructe d

by Vonage in its Prospectus "not to call us about the initial public offering or the Vonag e

Customer Directed Share Program." Instead , Vonage customers were told that the "Vonag e

Customer Directed Share Program [would] be centrally administered through the program

website at ipoinfo.vonage.com" (the "IPO Website") .

43 . Problems with the IPO Website and the dissemination of information to Subclas s

members quickly arose. With respect to the IPO Website, the Company, in its Prospectus ,

12

stated :

Our initial email communication to prospective participants in theVonage Customer Directed Share Program and the first page of thewebsite identified above (from which a reader could access a

detailed "frequently asked questions" section about the VonageCustomer Directed Share Program) did not include an activehyperlink to the prospectus contained in our most recently filedregistration statement relating to this offering as required pursuantto Rule 433 under the Securities Act . As a result, it is possible thatthe e-mail communication and the first page of the website couldbe determined to be an illegal offer in violation of Section 5 of theSecurities Act, in which case recipients could seek to recoverdamages or seek to require us to repurchase their shares at the IPOprice .

In addition, our initial voicemail communication to prospectiveVonage Customer Directed Share Program participants, whichcommunication may contain only limited information pursuant toRule 134 under the Securities Act, included the Internet address at

which prospective participants could obtain additional informationabout the Vonage Customer Directed Share Program, including acopy of the prospectus contained in our most recently filed

registration statement related to this offering. However, the

voicemail did not include the name and address of a person fromwhom such a prospectus could be obtained . The inclusion of theInternet address in the voicemail might be viewed as incorporating

into the voicemail information that is beyond the scope permissibleunder Rule 134. In addition, the omission of the name and addressof a contact person means that the voicemail would not be entitledto the "safe-harbor" provided by Rule 134 . As a result, it ispossible that the voicemail could be determined to be an illegaloffer in violation of Section 5 of the Securities Act, in which caserecipients could seek to recover damages or seek to require us torepurchase their shares at the IPO price .

44. The statements contained in 11 35-43 were materially false and misleading when

made because defendants failed to disclose or indicated the following: (1) that Vonage' s

technology platform experienced problems carrying telephone data over the networks of certain

Internet service providers, including Time Warner Inc's AOL; (2) that Vonage's VoIP

technology did not properly allow facsimile transmissions ; (3) that the Company did not

adequately inform investors about the history of Vonage's management team ; (4) specifically,

13

that Vonage failed to disclose that Tyco's ADT Security division took $600 million in charges

for accounting improprieties while defendant Snyder was President of the division ; (5) that the

Company did not adequately inform Vonage customers that opened brokerage accounts and

participated in Vonage's Directed Share Program concerning the customers' obligations to

purchase allocated shares; (6) specifically, that Vonage customers that participated in the

Directed Share Program were obligated to purchase allocated shares before they received notice

that their conditional offers had been accepted, and were led to believe that the IPO would take

place later than May 23, 2006 .

The Truth Begins to Emerge

45. On May 19, 2006, a class action lawsuit was filed in the United States District

Court for the District of New Jersey against Vonage and its U .S. subsidiary, Vonage America,

Inc. by two Vonage customers . The lawsuit, captioned Bustos and Watts v. Vonage America,

Inc. and Vonage Holdings Corp ., No. 06 Civ . 02308 (D.N.J .) (`Bustos and Watts Class Action")

alleged that Vonage's failures in the Company's facsimile services violated state common law

and the New Jersey Consumer Fraud Act .

46. The Bustos and Watts Class Action further alleged that Vonage failed to

adequately disclose that the Company's technology platform could not handle the transmission

of facsimiles to Vonage customers . Fascimile transmission via the Internet is plagued by "packet

loss," the failure of some of the data packets in which the facsimile is split up to transmit . To

prevent "packet loss," certain corrective measures may be utilitized, the most popular of which is

the "Transmission Control Protocol ." Vonage failed to implement any such corrective protocol,

yet continued to tout the reliability of its facsimile transmission capabilities . The Prospectus

made no mention of the Bustos and Watts Class Action or the allegations contained therein .

14

47, On May 24, 2006, CNBC initially reported that Vonage stated that the Company

would not "alienate" its customers by forcing payment from Vonage customers that refused t o

pay for their ]PO shares . Vonage further stated that the Company would repurchase any shares

from the Underwriter Defendants that were allocated to Vonage customers but remained unpaid .

48. Also on May 24, 2006, Vonage customers began to reveal problems they had with

the IPO. Specifically, FORBES .com reported, in relevant part :

Retail investors who participated in the Vonage initial publicoffering Wednesday got snared by glitches that tripped up theirability to bail after the debut quickly turned into a flop, with a 13%decline on the first day of trading .

Adding insult to injury, these investors-as many as 300 of them atone of the three principal trading houses where they could make

their transactions were also Vonage customers .

Some of Vonage's 1 .6 million subscribers were given a fairlyunique opportunity to participate in the IPO through a Vonageprogram that would distribute some 4 million shares to subscriberswho asked for them .

All the subscribers had to do was set up a limited-purposebrokerage account at either Citigroup's Smith Barney, UBS orDeutsche Bank's Alex. Brown. The three banks were the mainunderwriters on the IPO .

Vonage shares priced Tuesday night at $17, at the mid-range forthe targeted price, and subscribers who signed up to participate inVonage's "directed share program" were told Tuesday night howmany shares they would be getting and how much they'd have topay for them .

The shares opened flat in trading Wednesday and pretty quicklystarted to fall, down almost 5% by mid-morning . And when an

IPO stock starts to fall, everyone wants to sell .

But while the shares were falling, investors couldn't get through totheir brokers to make a sell order. One investor said he sat on holdfor 20 to 30 minutes, and even after getting through, he haddifficulty executing a sell order. "It was like 1994," said theinvestor (who requested anonymity), referring to that primitivetime before ubiquitous Internet access .

15

The self described professional investor (aka day trader) says hewas told by UBS that the Internet function set up for the Vonageprogram participants wasn't working. He had initially requestedan allocation of 3,000 shares and was given 800 shares, he said------and he lost about $800 by the time he got his sale executedWednesday morning .

He also said he couldn't get a quote on the stock or anyinformation about it via the Internet. At Smith Barney,information about Vonage's share price was also missing on the

client Web site . No Smith Barney representative was available forcomment .

A UBS spokeswoman confirmed that technical problems onWednesday affected some 10% of the 3,000 or so Vonage programparticipants the firm was working with, though not all of the 300had difficulty putting through sell orders, she said . "We areworking with our systems people to satisfy the needs of ourclients," she said.

A Vonage spokesman would not comment on anything, citing the

quiet period surrounding the IPO .

49. On May 30, 2006, TheStreet .com reported a similar story and stated, in relevant

part :

Last week's selloff taught one Vonage customer a lesson she won'tsoon forget .

Nina Schreiber, a novice investor who has been a Vonagecustomer since 2004, tried to buy shares in the Holmdel, N .J .-based company's initial public offering. Vonage, saying much ofits success has been "attributable to our customers," earlier thismonth allocated 15% of the IPO to users.

Earlier this month, Shreiber says she requested 5,000 Vonageshares, the most she could get .

On the evening of May 23, when the IPO was priced, Shreiber saysthe Vonage IPO Web site reported that her purchase never wentthrough.

"In big, huge, bold letters it said I was allocated zero, and that Iowed zero dollars," says Shreiber in an interview .

16

The next day, though, Shreiber was surfing the Internet again anddecided to take another peek at the IPO site . She was stunned tofind out that the site now said she had been awarded 1,300 sharesand owed $22,100 .

By then, Vonage shares had cratered more than 13% in the worstIPO debut since 2004. Now, Shreiber is working with her brokerto get out of the transaction.

"In my mind, I don't own this stock," Shreiber says .

A similar account is offered by Vonage customer DavidMcFeeters-Krone . He says he didn't realize he had acquiredshares until a statement came in the mail that he almost threw outin the trash .

"Anyway, I thought it was lame that their system screwed up and Iprobably held my shares a day or two longer than I would have

otherwise, but hey I obligated myself to this process," he writes inan email.

Others say they had a difficult time selling them.

"After the stock tanked, it took me hours to find out how to sell myshares," writes Vonage customer Bob Moriarty in an email . "I'mstill trying to find out how to get my cash out of the account ."

50. On May 31, 2006, Vonage reversed its previous position, and stated that th e

Company would undertake efforts to force Vonage customers to pay for their allocated shares .

51 . On this news, shares of Vonage traded to a low of $11 .52 per share, before

closing, on June 1, 2006, at $11 .63 per share . In the seven trading days after the IPO, shares o f

Vonage declined over 30 percent .

52. Reports of Vonage customers experiencing problems with the IPO Website

continued to surface. Specifically, the June 3-4, 2006 weekend edition of The Wall Stree t

Journal reported :

Yesterday, some customers-turned-shareholders said problems inthe online system for ordering shares delayed their attempts totrade, or led them to believe they didn't own shares when in facttheir orders had gone through and they did. As Vonage stock

17

dropped, these customers say, their losses mounted without their

knowledge .

Mr. Baden, for instance, says he signed up for 200 shares butwasn't notified of the $17 offering price or given a chance to

confirm his purchase before his deal went through. "I think it has

been very lousy as a customer experience," he says, adding that hehasn't decided whether he will contest the purchase .

Says Steve Norsworthy, a telecommunications engineeringconsultant from San Diego who bought 1,300 shares : "Vonageand the underwriters didn't do their jobs, and the customers whohelped make the company successful are taking it on the chin ." He

adds, "This is definitely cooling my interest in staying withVonage as a customer ."

Some customers who bought the IPO have even threatened towithhold payment, a step Vonage has said it will answer withcollection efforts .

***

A key issue, investors say, is a line from the IPO prospectus thatsaid Vonage would compensate its underwriters in the event thatcustomers didn't pay for the shares they had pledged to buy . Some

investors took that to mean they weren't obligated to pay .

In the first days of trading, the company added to the confusion bysuggesting on CNBC that it wasn't likely to play hardball withcustomers who balked . "While all avenues are available to us, wecannot imagine alienating our customers in that way," the companysaid in a statement on May 30 . If certain . . . customers don't pay,we expect to repurchase the shares from the underwriters ifnecessary . "

The statement set off a flood of speculation on www .vonage-fot•uni . co n and elsewhere that Vonage was allowing customers toback out and would buy shares back from customers . But a weekafter trading began, Vonage clarified that it wouldn 't buy back

shares and reserved the right to pursue payment. It sent customersemails reiterating their obligation to pay .

A spokesman for Citigroup's Smith Barney said the companyfound no technical glitches in its systems for handling custome r

18

orders. A spokesman for the securities unit of Deutsche Bankdeclined to comment .

A UBS spokesman said about 300 of its customers encounteredtechnical problems, such as being unable to log onto their accountsor complete trades . He said UBS has records of their efforts andphone calls if they couldn't trade online and would honor theirintentions. Citing a legally mandated quiet period, theunderwriters declined to comment on the pricing of the IPO andother aspects of the deal .

PLAINTIFF'S CLASS ACTION ALLEGATION S

53. Plaintiff brings this action as a class action pursuant to Federal Rule of Civi l

Procedure 23(a) and (b)(3) on behalf of a Class, consisting of all those who purchased or

otherwise acquired Vonage common stock pursuant or traceable to the Company's May 23, 2006

IPO, and who were damaged thereby (the "Class") . Excluded from the Class are defendants, the

officers and directors of the Company, at all relevant times, members of their immediate families

and their legal representatives, heirs, successors or assigns and any entity in which defendants

have or had a controlling interest .

54. Plaintiff also brings this action as a class action pursuant to Federal Rules of Civi l

Procedure 23(a) and (b)(3) on behalf of a Subclass, consisting of all Class members wh o

purchased or otherwise acquired Vonage common stock through the Vonage Directed Shar e

Program and were damaged thereby . Excluded from the Subclass are defendants , the officers

and directors of the Company, at all relevant times, members of their immediate families and

their legal representatives , heirs, successors or assigns and any entity in which defendants hav e

or had a controlling interest .

55 . The members of the Class and Subclass are so numerous that joinder of al l

members is impracticable . Throughout the Class Period, Vonage's common stock was actively

traded on the New York Stock Exchange ("NYSE"). While the exact number of Class an d

19

Subclass members is unknown to Plaintiff at this time and can only be ascertained through

appropriate discovery, Plaintiff believes that there are hundreds or thousands of members in th e

proposed Class and Subclass . Record owners and other members of the Class and Subclass may

be identified from records maintained by Vonage or its transfer agent and may be notified of th e

pendency of this action by mail, using the form of notice similar to that customarily used i n

securities class actions .

56. Plaintiffs claims are typical of the claims of the members of the Class an d

Subclass as all members of the Class and Subclass are similarly affected by defendants' wrongful

conduct in violation of federal law that is complained of herein .

57. Plaintiff will fairly and adequately protect the interests of the members of the

Class and Subclass and have retained counsel competent and experienced in class and securitie s

litigation.

58 . Common questions of law and fact exist as to all members of the Class an d

Subclass and predominate over any questions solely affecting individual members of the Clas s

and Subclass . Among the questions of law and fact common to the Class and Subclass are :

a. whether the federal securities laws were violated by defendants' acts as

alleged herein ;

b. whether statements made by defendants to the investing public during th e

Class Period misrepresented material facts about the business, operation s

and management of Vonage; and

c. to what extent the members of the Class and Subclass have sustained

damages and the proper measure of damages .

59. A class action is superior to all other available methods for the fair and efficien t

20

adjudication of this controversy since joinder of all members is impracticable . Furthermore, as

the damages suffered by individual Class and Subclass members may be relatively small, the

expense and burden of individual litigation make it impossible for members of the Class and

Subclass to individually redress the wrongs done to them. There will be no difficulty in the

management of this action as a class action .

UNDISCLOSED ADVERSE FACT S

60. The market for Vonage's common stock was open, well-developed and efficient

at all relevant times . As a result of these materially false and misleading statements and failures

to disclose, Vonage's common stock traded at artificially inflated prices during the Class Period .

Plaintiff and other members of the Class and Subclass purchased or otherwise acquired Vonage

common stock relying upon the integrity of the market price of Vonage's securities and market

information relating to Vonage, and have been damaged thereby .

61 . During the Class Period, defendants materially misled the investing public,

thereby inflating the price of Vonage's common stock, by publicly issuing false and misleading

statements and omitting to disclose material facts necessary to make defendants' statements, as

set forth herein, not false and misleading . Said statements and omissions were materially false

and misleading in that they failed to disclose material adverse information and misrepresented

the truth about the Company, its business and operations, as alleged herein .

62. At all relevant times, the material misrepresentations and omissions particularize d

in this Complaint directly or proximately caused or were a substantial contributing cause of the

damages sustained by Plaintiff and other members of the Class and Subclass . As described

herein, during the Class Period, defendants made or caused to be made a series of materially

false or misleading statements about Vonage's business, prospects and operations . These

21

material misstatements and omissions had the cause and effect of creating in the market an

unrealistically positive assessment of Vonage and its business, prospects and operations, thus

causing the Company's common stock to be overvalued and artificially inflated at all relevant

times. Defendants' materially false and misleading statements during the Class Period resulted

in Plaintiff and other members of the Class purchasing the Company's common stock at

artificially inflated prices, thus causing the damages complained of herein . ,

LOSS CAUSATIO N

63 . Defendants' wrongful conduct, as alleged herein, directly and proximately caused

the economic loss suffered by Plaintiff and the Class and Subclass .

64. During the Class Period, Plaintiff and the Class and Subclass purchased the

common stock of Vonage at artificially inflated prices and were damaged thereby. The price of

Vonage's common stock declined when the misrepresentations made to the market, and/or the

information alleged herein to have been concealed from the market, and/or the effects thereof,

were revealed, causing investors' losses .

Applicability of Presumption of Reliance :Fraud On The Market Doctrine

65 . At all relevant times, the market for Vonage common stock was an efficient

market for the following reasons, among others:

a. Vonage stock met the requirements for listing, and was listed and actively

traded on the NYSE, a highly efficient and automated market ;

b . As a regulated issuer, Vonage filed periodic public reports with the SEC

and the NYSE;

c. Vonage regularly communicated with public investors via established

market communication mechanisms, including through regular

22

disseminations of press releases on the national circuits of major newswire

services and through other wide-ranging public disclosures, such as

communications with the financial press and other similar reporting

services ; and

d. Vonage was followed by several securities analysts employed by major

brokerage firms who wrote reports which were distributed to the sales

force and certain customers of their respective brokerage firms. Each of

these reports was publicly available and entered the public marketplace .

66. As a result of the foregoing, the market for Vonage common stock promptly

digested current information regarding Vonage from all publicly-available sources and reflected

such information in Vonage's stock price . Under these circumstances, all purchasers of Vonage

common stock during the Class Period suffered similar injury through their purchase of Vonage

common stock at artificially inflated prices and a presumption of reliance applies .

NO SAFE HARBOR

67. The statutory safe harbor provided for forward-looking statements under certain

circumstances does not apply to any of the allegedly false statements pleaded in this complaint .

Many of the specific statements pleaded herein were not identified as "forward-looking

statements" when made. To the extent there were any forward-looking statements, there were no

meaningful cautionary statements identifying important factors that could cause actual results to

differ materially from those in the purportedly forward-looking statements . Alternatively, to the

extent that the statutory safe harbor does apply to any forward-looking statements pleaded

herein, defendants are liable for those false forward-looking statements because at the time each

of those forward-looking statements was made, the particular speaker knew that the particular

23

forward-looking statement was false, and/or the forward-looking statement was authorized

and/or approved by an executive officer of Vonage who knew that those statements were false

when made .

FIRST CLAIMViolation of Section 11 of the

Securities Act Against All Defendants

68 . Plaintiff repeats and realleges each and every allegation contained above as if fully

set forth herein only to the extent, however, that such allegations do not allege fraud, scienter or

the intent of the defendants to defraud Plaintiff or members of the Class and Subclass . This

count is predicated upon defendants' strict liability for making false and materially misleading

statements in the Registration Statement and Prospectus .

69. This claim is asserted by Plaintiff against all defendants by and on behalf of

persons who acquired shares of the Company pursuant to or traceable to the false Registration

Statement and Proxy Statement issued in connection with the May 2006 IPO .

70. Individual Defendants as signatories of the Registration Statement and th e

Prospectus, as directors and/or officers of Vonage and controlling persons of the issuer, owed to

the holders of the stock obtained through the Prospectus the duty to make a reasonable and

diligent investigation of the statements contained in the Registration Statement and the

Prospectus at the time they became effective to ensure that such statements were true and correct

and that there was no omission of material facts required to be stated in order to make the

statements contained therein not misleading . Defendants knew, or in the exercise of reasonable

care should have known, of the material misstatements and omissions contained in or omitted

from the Registration Statement and the Prospectus as set forth herein . As such, defendants are

liable to the Class and Subclass .

grounds for the belief that the statements contained in the Registration Statement and th e

Prospectus were true or that there was no omission of material facts necessary to make th e

statements made therein not misleading .

73 . Defendants issued and disseminated, caused to be issued and disseminated, an d

participated in the issuance and dissemination of, material misstatements to the investing publi c

which were contained in the Prospectus, which misrepresented or failed to disclose, inter alia ,

the facts set forth above. By reason of the conduct herein alleged, each defendant violated and/o r

controlled a person who violated Section i i of the Securities Act .

74. As a direct and proximate result of defendants' acts and omissions in violation o f

the Securities Act, the market price of Vonage stock sold in the IPO was artificially inflated an d

Plaintiff and the Class and Subclass suffered substantial damage in connection with thei r

ownership of Vonage common stock pursuant to the Registration Statement and the Prospectus .

75. Vonage is the issuer of the stock sold via the Registration Statement . As issuer of

the stock, the Company is strictly liable to Plaintiff and the Class and Subclass for the material

25

misstatements and omissions therein.

76. At the times they obtained their shares of Vonage, Plaintiff and members of the

Class and Subclass did so without knowledge of the facts concerning the misstatements or

omissions alleged herein .

77. This action is brought within one year after discovery of the untrue statements and

omissions in and from the Prospectus which should have been made through the exercise of

reasonable diligence, and within three years of the effective date of the Prospectus .

78 . By virtue of the foregoing, Plaintiff and the other members of the Class an d

Subclass are entitled to damages under Section 11 as measured by the provisions of Section

11(e), from the defendants and each of them, jointly and severally .

not misleading, and concealed and failed to disclose material facts . The Individual Defendants '

actions of solicitation included participating in the preparation of the false the misleading

Prospectus and Registration Statement .

26

83. Defendants owed to the purchasers of Vonage common stock, including Plaintiff

and other members of the Class and Subclass, the duty to make a reasonable and diligent

investigation of the statements contained in the IPO materials, including the Proxy-Prospectus

and Registration Statement, to ensure that such statements were true and that there was no

omission to state a material fact required to be stated in order to make the statements contained

therein not misleading . Defendants knew of, or in the exercise of reasonable care should have

known of, the misstatements and omissions contained in the IPO materials as set forth above .

84. Plaintiff and other members of the Class and Subclass purchased or otherwis e

acquired Vonage common stock pursuant to and/or traceable to the defective Proxy-Prospectus .

Plaintiff did not know, or in the exercise of reasonable diligence could not have known, of th e

untruths and omissions contained in the Prospectus .
