28 CLASS ACTION COMPLAINT 1 Plaintiff, Eugene L. Hammer ("Plaintiff'), individually and on behalf of all other persons

2 similarly situated, alleges the following based upon personal knowledge as to Plaintiff and Plaintiffs'

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

4 investigation conducted by and through Plaintiff's counsel, which included, among other things: a

5 review of the Defendants' public documents, conference calls and announcements made by

6 Defendants; United States Securities and Exchange Commission (the "SEC") filings by BigBand

7 Networks Inc. ("BigBand" or the "Company") and its related entities; wire and press releases

8 published by and regarding BigBand; securities analysts' reports and advisories about the Company;

9 and information readily obtainable on the Internet.

10 NATURE OF THE ACTIONS

11 1. This is a federal class action brought by Plaintiff on behalf of all purchasers of Bi

12 common stock between March 14, 2007, and September 27, 2007, (the "Class Period") against BigBE

13 and certain of its officers and directors ("Defendants"). Purchasers include those who purcha:

14 BigBand common stock pursuant or traceable to the Company's amended registration statement gig

15 effect on March 14, 2007 ("Registration Statement") through a Form S-1 SEC filing, and the prospec

16 dated March 14, 2007, (individually and collectively with the Registration Statement, the "Prospectu

17 issued in connection with the Company's initial public offering on or about March 14, 2007, (

18 "Offering" or the "IPO"). Plaintiff seeks to pursue remedies under the Securities Act of 1933 (

19 "Securities Act") and the Securities Exchange Act of 1934 (the "Exchange Act").

20 2. BigBand develops, markets, and sells broadband multimedia infrastructure for

21 voice and data enabling cable operators and telephone companies to offer voice, video and data servi

22 across coaxial fiber and copper networks . BigBand is incorporated in Delaware and headquartered

23 Redwood City, California. The Company has research and development facilities in Westborou€

24 Massachusetts, Tel Aviv, Israel and Redwood City, California.

25 3. On March 14, 2007, BigBand and Company insiders completed an IPO, selling 7

26 million shares of BigBand common stock from the Company and 4.8 million shares of

27

28 1 CLASS ACTION COMPLAINT 1I common stock from selling stockholders, for a total of 12.3 million shares at $13 per share for

21 proceeds totaling $159.9 million.

3 4. During the Class Period, however, Defendants made false and misleading

4 regarding the Company's business prospects, financial results and forward guidance. Defendants faile

5 to disclose that the Company had achieved revenue growth and profitability at the end of 2006 only as

6 result of non-recurring orders from Inc. ("Verizon"). As a result, BigBar

7 would not achieve further revenue growth from Verizon until Verizon worked off the inventor

8 purchased in late 2006 and early 2007. Rather, Defendants stated that BigBand would achiei

9 aggressive revenue and profit projections, misrepresenting and omitting the truth with regard I

10 Verizon's need to deplete its excess inventory. BigBand also failed to disclose that delays wei

11 occurring in the customization of certain customer specific products involving switched digital vide

12 ("SDV") technology. The viability of the Company's cable modem termination system ("CMTS") w,

13 also in doubt. Not only were these problems contributing to its failure to achieve revenue and pros

14 projections, they caused the Company to lack an objectively reasonable basis to make busine

15 projections and forward guidance during the Class Period.

16 5. After the market closed on September 27, 2007, the Company, through a press

17 revealed the truth of its product development problems. BigBand announced that it was revising i

18 revenue outlook for the third quarter ending September 30, 2007. The Company revealed that it no

19 expected to report revenue for the third quarter in the range of $35 million to $39 million, as much

20 $23 million below the Company's previous guidance of $54 million to $58 million. BigBand attribute

21 the dramatic decline in expectations to one customer, not named but assumed to be Verizon, havir

22 excessive inventory of BigBand's products and with no expectation to increase its purchases in tl

23 immediate future. The press release also revealed that BigBand was having difficulty obtainir

24 customer acceptance of other products necessary for revenue recognition. BigBand stated that all the;

25 issues were expected to persist for a number of quarters.

26 6. On this news, shares ofthe Company's stock fell nearly $2.67 per share, or 29.4

27 to close, on September 28, 2007, at $6.40 per share. 2 28 CLASS ACTION COMPLAINT 1 JURISDICATION AND VENUE

27 5 28 CLASS ACTION COMPLAINT 1 C /"'PTT 1^TTT' 1

21 24. As alleged herein, Defendants acted with scienter in that Defendants knew that the

3 documents and statements issued or disseminated in the name ofthe Company were materially false an(

4 misleading; knew that such statements or documents would be issued or disseminated to the investing

7 detail, Defendants, by virtue of their receipt of information reflecting the true facts regarding BigBand

8 their control over, and/or receipt and/or modification of BigBand's allegedly materially misleading

91 misstatements and/or their associations with the Company which made them privy to confident

10 1 proprietary information concerning BigBand, participated in the fraudulent scheme alleged herein.

11 CLASS ACTION ALLEGATIONS

12 25. Plaintiff brings this action as a class action pursuant to Federal Rule of Civil

13 23(a) and (b)(3) on behalf of a Class consisting of all purchasers of the publicly traded securities o

14 BigBand during the Class Period, including purchasers of BigBand securities pursuant or traceable to

15 Registration Statement and Prospectus issued in connection with the Company's IPO (the "Class").

16 26. Excluded from the Class are Defendants, the officers and directors ofthe Company at

17 relevant times, members oftheir immediate families and their legal representatives, heirs, successors

18 assigns and any entity in which Defendants have or had a controlling interest.

19 27. Questions of law and fact common to the members of the Class which predominate

20 questions which may affect individual Class members include:

21 i. Whether the federal securities laws were violated by Defendants by the acts

22 herein;

23 ii. Whether Defendants omitted and/or misrepresented material facts to the

24 public during the Class Period about the business, operations and management o

25 BigBand;

26 iii. Whether Defendants' statements omitted material facts necessary to make

27 statements made, in light of the circumstances under which they were made, 6 28 CLASS ACTION COMPLAINT I misleading;

2 iv. Whether Defendants knew or deliberately disregarded that their statements were

3 and misleading;

4 v. Whether the price of BigBand common stock was artificially inflated; and

5 vi. The extent of damage sustained by Class members and the proper measure of dama

6 28. At all relevant times, the market for BigBand securities was an efficient market for

7 following reasons:

8 i. BigBand securities were actively traded on NASDAQ, an efficient and

9 market;

10 ii. During the Class Period, thousands of shares of BigBand securities were

11 on the open market;

12 iii. BigBand filed periodic public reports with the SEC and the NASDAQ fol

13 the responsibilities of a regulated issuer of stock; and

14 iv. BigBand was covered by multiple securities analysts employed by differ,

15 brokerage firms. Reports were penned by these analysts that were distributed

16 their respective brokerage firms. These reports were publicly available z

17 entered the public marketplace.

18 29. Plaintiff's claims are typical of those of the Class because the market for BigBz

19 securities absorbed current information regarding the Company from all publicly available sources a

20 reflected that information in BigBand's share price. Under these circumstances, all purchasers of 1

21 Company's common shares during the Class Period suffered similar injury through their purchase

22 shares at artificially inflated prices and presumably relied upon the information publicly available.

23 30. The members of the Class are so numerous that joinder of all members is impracticab

24 The disposition of their claims in a class action will provide substantial benefits to the parties and

25 Court. Throughout the Class Period, BigBand securities were actively traded on NASDAQ

26 millions of shares of stock outstanding, owned by hundreds, if not thousands, of persons. While

27 exact number of Class members is unknown to Plaintiff at this time and can only be ascertained thro

1) Qn 7 -- 11 CLASS ACTION COMPLAINT 1 I appropriate discovery, Plaintiff believes that there are hundreds or thousands of members in

2 proposed Class.

3 31. Plaintiff will adequately protect the interests of the Class and has retained counsel

4 are experienced in class action securities litigation. Plaintiff has no interests which conflict with those

5 the Class.

61 32. A class action is superior to other available methods for the fair and efficient

7 of this controversy. Furthermore, as the damages suffered by individual Class members may

8 relatively small, the expense and burden of individual litigation make it impossible for members of

9 Class to individually redress the wrongs done to them. Plaintiff's counsel is experienced in comp

10 litigation of this nature and there will be no difficulty in the management of this case as a class acti

11 SUBSTANTIVE ALLEGATIONS

12 33. BigBand recognizes revenue mainly from the sale of products. BigBand's

13 revenue source is derived from the sale of services. In 2006, the sale ofproducts netted BigBand $154.

14 million in revenue (approximately 87.2% of total net revenue), and the sale of services netted Bi

15 $22.6 million in revenue (approximately 12.8% of net revenue).

16 34. BigBand product sales are divided primarily into three markets : TelcoTV, Sw

17 Broadcast video, and data.

18 35. BigBand's TelcoTV sales have historically been primarily sales to Verizon. The prop

19 is however, available to all telephone companies that use a broadband multimedia-service router (BT

20 such as BigBand' s for the real-time processing and switching ofvideo. BigBand states in its Prospe

21 that its TelcoTV products are a major attraction to telephone companies for reasons of convenience

22 cost savings.

23 We enable telephone companies to leverage their existing Synchronous Optical Network, or SONET, infrastructure which was originally designed for voice communications, to transport 24 video content throughout the network. This provides significant cost savings as telephone companies are not required to build a dedicated video transport network. 25

26 36. According to BigBand's Prospectus, there are some unique and innovative aspects

27 BigBand's Switched Broadcast application: 8 28 CLASS ACTION COMPLAINT Our Switched Broadcast application enables service providers to transmit video channels to subscribers only when the subscribers in a smaller subset of subscribers within the network, 2 called a service group, are in the process of watching those channels. Depending on the number of subscribers and the amount of duplicate channels within a service group, our 3 Switched Broadcast product application typically allows service providers to achieve up to 4 50% bandwidth savings in the delivery of digital video content and use the reclaimed bandwidth to offer additional content. 5 37. However, the company's commercial products were hardly that, since BigBand 6 growing undisclosed product implementation woes and serious product commercialization issues 7

8 potentially would have derailed the Company's financial projections claims.

9 FALSE AND MISLEADING STATEMENTS ISSUED BY DEFENDANTS

10 38. On or about March 14, 2007, BigBand filed with the SEC a Form S-1 11 Registration Statement for its IPO. The SEC issued an Effectiveness Order, and the S-1 became 12 March 14, 2007. 13 39. From approximately March 14, 2007 to March 20, 2007, the Company sold 7.5 14

15 shares of BigBand common stock and selling stockholders sold 4.8 million shares, for a total of 1

16 million shares at $13 per share for proceeds totaling $159.9 million. (Form 8-K, March 20, 2007)

17 Individual Defendants Bassan-Eskenazi, Oz, Gilbert, and Israely all sold stock as a part of the initi 18 public offering for a profit of approximately $16.4 million. 19 40. In the Prospectus, BigBand represented, among other things, that it had experienced 20 revenue growth from 2005 to 2006 (from $98.0 million to $176.6 million) and had operated profitably 21 the third and fourth quarters of 2006 and overall for the year. The Registration Statement stated in part: 22

23 We develop, market and sell network-based platforms that enable cable operators and telephone companies, collectively called service providers, to offer video, voice and 24 data services across coaxial, fiber and copper networks. We have significant expertise in rich media processing, communications networking and bandwidth management. 25 We have delivered what we believe to be the only successful commercial deployments of switched broadcast, an application that substantially increases the 26 volume of content that a service provider can offer. In addition, we were the first to 27 implement what we believe has become the industry's de facto network architecture 9 28 CLASS ACTION COMPLAINT for digital simulcast, an application that facilitates the insertion of advertising and the transmission of video in a digital format across a network while still providing service 2 to analog subscribers . Our product applications of Digital Simulcast, TelcoTV, Switched Broadcast, and High-Speed Data 3 and Voice-over-IP are a combination of our modular software and programmable video and data hardware platforms. 4 Our software and hardware product applications are used by leading service providers 5 worldwide to offer video, voice and data services to tens of millions of subscribers, 24 hours a day, seven days a week. We have sold our product applications to more than 6 100 customers globally, including , Charter, , Cox, and Verizon, which are six 7 of the ten largest service providers in the United States. Our net revenues increased 80.3% to $176.6 million for the year ended 8 December 31, 2006 from $98.0 million in 2005. We have been profitable on a quarterly basis since the three months ended September 30, 2006, and we first 9 achieved profitability on an annual basis in 2006. 10 41. In the Company' s Registration Statement, BigBand stated that product sales during 11 were a result of an $87.6 million increase in revenues from video products, partially offset by a $19. 12 million decrease in revenues from data products. The Registration Statement further stated that a primar 13 reason for the $87.6 million growth in video product revenues during 2006 was that the Company sa` 14

15 the first recognizable net revenues from BigBand's TelcoTV product:

16 Net revenues for 2006 were $176.6 million compared to $98.0 million for 2005, an increase of $78.6 million, or 80.3%. Revenues from our top five customers comprised 17 79% and 69% of net revenues for 2006 and 2005, respectively. During 2006, revenues from customers in the United States comprised 89% of net revenues, and revenues 18 from customers outside the United States comprised 11 % of net revenues, compared 19 to the same period in 2005, in which customers in the United States comprised 83% of net revenues, and revenues from customers outside the United States comprised 17% 20 of net revenues.

21 Products revenues for 2006 were $154.0 million compared to $86.0 million for 2005, an increase of $68.0 million, or 79.2%. This increase was primarily due 22 to a $87.6 million increase in revenues from our video products, partially offset by a $19.6 23 million decrease in revenues from our data products. The $87.6 million increase in video products was attributable to the first recognition of significant net revenues 24 from our TelcoTV product and significant growth in revenues from our Switched Broadcast product. The decrease in revenues from data products was almost entirely 25 due to $18.8 million of revenues recognized in 2005 following satisfaction of customer acceptance criteria for product shipped 26 to a single customer in 2004.

27

28 10 CLASS ACTION COMPLAINT 42. According to the Registration Statement, BigBand's "sales cycle for an initial

2 purchase typically ranges from nine to eighteen months..." However, "[a]fter initial deployment of 3 products, subsequent purchase of our products typically have a more compressed sales cycle." 4 43. Approximately 89% of BigBand' s sales in 2006 were to customers in the United 5 BigBand sells its products and services to customers in the United States through a direct sales force. 6 44. The Registration Statement described BigBand's sales as highly concentrated among 7

8 five largest customers . Over time, sales to those customers became more concentrated, equaling 90%

9 revenue in the fourth quarter of 2006. The Registration Statement further indicated that sales at the

10 of the filing were concentrated among four customers : Comcast, Cox, Time Warner Cable and V 11 Each of these four customers represented more than 10% of sales during 2006: 12 A substantial majority of our sales have been to relatively few customers. However, 13 our large customers have changed over time. Sales to our five largest customers represented 79%, 69% and 61% of our net revenues in the year ended December 31, 14 2006, the year ended December 31, 2005, and the year ended December 31, 2004, respectively, and were particularly significant in the three months ended 15 December 31, 2006 when they represented approximately 90% of our net 16 revenues. In 2006, Comcast, Cox, Time Warner Cable and Verizon each represented 10% or more of our net revenues. In 2005, Adelphia, Cox and Time Warner Cable 17 each represented 10% or more of our net revenues. In 2004, Adelphia, Comcast, Cox and Time Warner Cable each represented 10% or more of our net revenues. Although 18 we are attempting to broaden our customer base by penetrating new markets and expect continuing customer concentration due to the 19 expanding internationally, we significant capital costs of constructing service provider networks and industry 20 consolidation. We expect that in future periods a limited number of large customers will continue to comprise a large percentage of our revenues. 21 45. In the Company 's Prospectus, BigBand stated that the Company had maintained a 22 established backlog: 23 customer commitment demonstrated through its

24 We schedule production of our products based upon our backlog, open contracts, informal commitments from customers and sales projections . Our backlog consists 25 of firm purchase orders by customers for delivery within the next six months. As of December 31, 2006, we had backlog of $36.2 million, compared with backlog of 26 $33.1 million as of December 31, 2005. Anticipated orders from customers may fail of 27 to materialize and delivery schedules may be deferred or canceled for a number 11 28 CLASS ACTION COMPLAINT 1 reasons, including reductions in capital spending by service providers or changes in specific customer requirements. Because of the complexity of our customer 2 acceptance and revenue recognition criteria, in addition to backlog, we have significant deferred revenues. As a result, our backlog alone is not necessarily 3 indicative of revenues for any succeeding period. 4 46. BigBand reported $56.7 million in net revenue and $8.9 million in net income for 5 fourth quarter of 2006 according to the Prospectus. 6 47. The statements referenced above were each materially false and misleading because 7

8 failed to disclose and misrepresented at least the following adverse facts: (1) that the Company

9 distorted the growth in its sales through the method of channel stuffing on sales of TelcoTV products

10 Verizon prior to the IPO; and (2) BigBand was experiencing delays in customer acceptance of 11 specific products due to difficulty in customizing these products. 12 48. In reliance on the truth and accuracy of the representations contained in the 13 with respect to BigBand's business, BigBand common stock traded from March 15, 2007 (the first 14 BigBand common stock traded) and May 3, 2007 between $17.00 and $21.43 per share. 15

16 49. On May 3, 2007, after the close of trading on U.S. securities markets, BigBand issued

171 press release reporting first quarter 2007 financial results. For the quarter ended March 31, 2007

18 BigBand reported net revenues of $52.8 million (62% over the prior year) and a GAAP net loss of $1. 19 million or ($0.05) per diluted share. The company reported that non-GAAP results (excluding 20 non-cash charges) were $5 . 8 million, or $0.09 per diluted share . (Form 8-K, May 3, 2007). 21 50. Defendants Bassan-Eskenazi-Eskanazi was quoted in the press release as stating: 22

23 During the quarter, we continued to see an expansion of our installed base of solutions and of the capacity of our existing footprint, which favorably benefited our gross 24 margin.

25 We are delighted to report strong financial results for the first quarter of 2007, our first quarter as a public company. Some of the world's largest cable and 26 telecommunications carriers continue to demonstrate interest in our media services 27 12 28 CLASS ACTION COMPLAINT platforms, built upon a unique combination of networking, video processing, and bandwidth management capabilities. 2 We believe that our financial achievements to date demonstrate the increasing 3 consumer demand for more and better video services, including high-definition 4 programming. Our growth continues to be a function of the broader adoption of our switched broadcast solution by major cable operators and the increasing deployment 5 of television services by telecommunications carriers, among many other initiatives.

6 Looking ahead, we are optimistic about our business and long-term market opportunity. We expect to further leverage our platform and gain footprint with new 7 customers in new geographies. BigBand Networks continues to innovate, and we 8 believe our technology will remain a key point of differentiation in the future.

9 51. The May 3, 2007 press release reported that management anticipated net revenues for

10 second quarter of 2007 would be in the range of approximately $52 to $56 million and that 11 earnings per share would be in the range of $0.02 to $0.06 per share. For 2007, net revenues 12 anticipated to be in the range of approximately $225 to $230 million, and GAAP earnings per share 13 anticipated to be in the range of $0.06 to $0.11 per share. 14 52. On a conference call conducted immediately after the issuance of the May 3, 2007 15

16 release, Defendant Bassan-Eskenazi stated that BigBand's "switched broadcast solution continue to be

17 major driver of our business... We are now deploying our fourth-generation switched broadcast produce

18 while many competitors are still developing their first and switched broadcast is a fraction of the cost c 19 competing alternatives.... Time Warner Cable was the first major cable operator to adopt switche 20 broadcast. During the first quarter of 2007, we recognized revenue associated with Cablevision' 21 deployment of switched broadcast, the second [Multiple System Operator] to adopt our solution." 22 "continuing demand for [its' 23 53. Bassan-Eskenazi further stated that BigBand was seeing

24 TelcoTV solutions" in the first quarter:

25 BigBand carrier-grade platform is deployed at the edge of our Telco customers' networks and is used to ensure reliable and efficient delivery of TV programming. We 26 continue to support the ongoing rollout of Verizon's FiOS TV. Our ability to 27 successfully deploy with this important customer gives us the confidence in our 13 28 CLASS ACTION COMPLAINT 1 platform fit for TelcoTV, as well as validates our ability to add value to this important market segment. 2 54. On that same conference call, Defendant Ball assured investors that he had good visibi 3

4 on projecting second quarter operations and at the end ofthe second quarter would have an equally

5 basis for projecting third quarter operations: "I still view the world as a kind of six- month window.

6 have a ... pretty good view of Q2 . I have a little bit less so view of Q3. There are some things that 7 to happen in Q2 for me to fill in Q3...." 8 55. With regard to certain orders where the products had not yet been deployed, Ball 9 that "our typical pattern from switched broadcast orders is kind of a six-to-nine month window 10 revenue or sign-off by the customers," and those orders where products had not been deployed were 11

12 included in current period projections.

13 ADVERSE FACTS HIDDEN FROM THE PUBILC, NOW REVEALED

14 56. On August 2, 2007, after the close ofthe U. S. securities markets, BigBand issued a 15 release reporting second quarter 2007 operating results. Net revenues for the second quarter 16 reported at $54.5 million (43% over the prior year). GAAP net income for the quarter was $1.7 17 or $0.02 per diluted share. Defendant Bassan-Eskenazi was quoted in the press release as stating: 18 our improvements in both revenues and earnings results in the second 19 We are pleased with quarter. We continued to drive significant expansion of the footprint of our media service 20 platforms. We continue to work closely with customers in supporting their efforts to enhance their existing networks for advanced video services. We believe that BigBand's 21 solutions for switched broadcast and TelcoTV will continue to gain traction with major customers both in the U.S. and internationally. 22 *** 23 Video continues to be a major driver of capital expenditures in service provider networks. 24 We believe that our technology, innovation and time-to-market leadership are key competitive differentiators in our video and data markets. Our product roadmap calls for 25 more innovation as the industry moves to addressable advertising and personalized video services. We continue to be well positioned for additional growth over the long-term 26 and are optimistic about our business. [emphasis added] 27 14 28 CLASS ACTION COMPLAINT 1 57. The August 2, 2007 press release added that management ' s current expectations for

2 third quarter were net revenues of approximately $54 to $58 million, and GAAP earnings (loss) 3 share in the range of ($0.01) to $0.03 per share . The Company again indicated that net revenues 4 anticipated to be in the range of approximately $225 to $230 million, and that GAAP earnings per 5 were anticipated to be in the range of $0.03 to $0.08 per share. This was less than previous 6 forecasts for revenues and earnings. 7

8 58. On a conference call conducted on August 2, 2007, immediately after issuance of

9 August 2, 2007, press release, Defendant Bassan-Eskenazi sought to quell investor discontent caused

10 the reduced income forecast. Bassan-Eskenazi assured investors that "[w]e are growing our top-line as 11 direct impact ofthe healthy demand for the unique video solutions which drive strategic footprint 12 with key customers." Bassan-Eskenazi added that "[t]he competition among cable, satellite and 13 providers is accelerating, and is causing all of them to invest heavily and add new capabilities to 14 network. growing industry second quarter we experienced 15 As a result of these trends, in the

16 growth, meaningful design wins, and significant milestones."

17 59. On September 27, 2007, after the close of trading on U.S. securities markets, BigB 18 announced in a press release entitled "BigBand Networks Announces Revised Revenue Outlook 19 Third Quarter of 2007" that it was revising "its revenue outlook for the third quarter ending 20 30, 2007." The Company now expected to "report revenue for the third quarter in the range of $35 21 $39 million," which was "below the Company's previous guidance of $54 to $58 million" by as much 22

23 23 million. BigBand's revised revenue forecast for the third quarter reflected no revenue growth

24 revenue for the third quarter of 2006.

25 60. BigBand attributed the reduced revenue outlook "to several coincident factors": 26

27 15 28 CLASS ACTION COMPLAINT 1 i. Referencing the deployment of switched digital video across "an expanding

2 number of customers and configurations," BigBand explained that "[s]ome ... 3 deployments have required more software customization and integration than 4 originally expected. This impacted the Company's ability to recognize 5 switched digital revenue for some deployments in the third quarter"; 6

7 ii. Because a "major customer" (presumably Verizon) "worked through some

8 previously purchased inventory" TelcoTV revenue was reduced; 9 iii. BigBand "experienced continued softness in its data business." 10

11 61. The September 27, 2007, press release added that "[a]s a result of lower revenue

12 expectations, BigBand expects to report an operating loss for the third quarter of fiscal year 13 2007."Bassan-Eskenazi's comments in the press release included in relevant part: 14 While we believe the market for our video solutions continues to be strong and are 15 confident in our roadmap for the long term, we are clearly disappointed in our execution this quarter. We are aggressively addressing these issues and will provide 16 more specifics in our announcement of third quarter financial results in early November. 17

18 62. Once the true status of BigBand's product development problems came to light, BigBan 19 was forced to reveal to the market its current and potential depressed financial performance and outlook. 20 In response to this negative news, the market quickly reacted. Shares ofthe Company's stock fell $2.6 21

22 per share, or 29.4 percent, to close, on September 28, 2007, at $6.40 per share.

23 63. Morgan Keegan analyst Simon Leopold cut his rating on the stock to market perform

24 from outperform. Jefferies & Co. also cut its rating on the company to hold from buy, reducing 2007 25 revenue estimates to $181.7 million from $224.6 million. Jefferies analyst George Notter said in 26 research note, "[w]e recommend that investors stay on the sidelines." 27 16 28 CLASS ACTION COMPLAINT 1 64. The nearly 28% decline in the price of BigBand Networks stock on August 3, 2007, anc

2 the subsequent 29% decline on September 28, 2007, at the end ofthe Class Period, were the direct resul- 3 of the nature and extent of Defendants ' fraud finally being revealed to investors and the market. The 4 timing and magnitude of BigBand Networks ' stock price declines negate any inference that the los: 5 suffered by Plaintiff and other Class members was caused by changed market conditions 6 macroeconomics or industry factors or Company-specific facts unrelated to the Defendants' fraudulen 7

8 conduct.

10 65. On October 18, 2007, Frederick Ball stepped down as Chief Financial Officer o: 11 BigBand.

INSTRUCTIONS FOR ATTORNEYS COMPLETING CIVIL COVER SHEET FORM JS-44 Authority For Civil Cover Sheet

The JS-44 civil cover sheet and the information contained herein neither replaces nor supplements the filings and service of pleading or other papers as required by law, except as provided by local rules of court. This form, approved by the Judicial Conference of the United States in September 1974, is required for the use of the Clerk of Court for the purpose of initiating the civil docket sheet. Consequently a civil cover sheet is submitted to the Clerk of Court for each civil complaint filed. The attorney filing a case should complete the form as follows:

1. (a) Plaintiffs - Defendants. Enter names (last, first, middle initial) of plaintiff and defendant. If the plaintiff or defendant is a government agency, use only the full name or standard abbreviations. If the plaintiff or defendant is an official within a government agency, identify first the agency and then the official, giving both name and title.

(b) County of Residence. For each civil case filed, except U.S. plaintiff cases, enter the name of the county where the first listed plaintiff resides at the time of filing. In U.S. plaintiff cases, enter the name of the county in which the first listed defendant resides at the time of filing. (NOTE: In land condemnation cases, the county of residence of the "defendant" is the location of the tract of land involved.)

(c) Attorneys. Enter the firm name, address, telephone number, and attorney of record. If there are several attorneys, list them on an attachment, noting in this section "(see attachment)".

II. Jurisdiction. The basis of jurisdiction is set forth under Rule 8(a). F.R.C.P., which requires that jurisdictions be shown in pleadings. Place an "X" in one of the boxes. If there is more than one basis of jurisdiction, precedence is given in the order shown below.

United States plaintiff. (1) Jurisdiction based on 28 U.S.C. 1345 and 1348. Suits by agencies and officers of the United States are included here.

United States defendant. (2) When the plaintiff is suing the United States, its officers or agencies, place an "X" in this box.

Federal question. (3) This refers to suits under 28 U.S.C. 1331, where jurisdiction arises under the Constitution of the United States, an amendment to the Constitution, an act of Congress or a treaty of the United States. In cases where the U.S. is a party, the U.S. plaintiff or defendant code takes precedence, and box 1 or 2 should be marked.

Diversity of citizenship. (4) This refers to suits under 28 U.S.C. 1332, where parties are citizens of different states. When Box 4 is checked, the citizenship of the different parties must be checked. (See Section III below; federal question actions take precedence over diversity cases.)

III. Residence (citizenship) of Principal Parties. This section of the JS-44 is to be completed if diversity of citizenship was indicated above. Mark this section for each principal party.

IV. Origin. Place an "X" in one of the seven boxes.

Original Proceedings. (1) Cases which originate in the United States district courts.

Removed from State Court. (2) Proceedings initiated in state courts may be removed to the district courts under Title 28 U.S.C., Section 1441. When the petition for removal is granted, check this box.

Remanded from Appellate Court. (3) Check this box for cases remanded to the district court for further action. Use the date of remand as the filing date.

Reinstated or Reopened. (4) Check this box for cases reinstated or reopened in the district court. Use the reopening date as the filing date.

Transferred from Another District. (5) For cases transferred under Title 28 U.S.C. Section 1404(a). Do not use this for within district transfers or multidistrict litigation transfers.

Multidistrict Litigation. (6) Check this box when a multidistrict case is transferred into the district under authority of Title 28 U.S.C. Section 1407. When this box is checked, do not check (5) above.

Appeal to District Judge from Magistrate Judgment. (7) Check this box for an appeal from a magistrate judge's decision.

V. Nature of Suit. Place an "X" in the appropriate box. If the nature of suit cannot be determined, be sure the cause of action, in Section IV above, is sufficient to enable the deputy clerk or the statistical clerks in the Administrative Office to determine the nature of suit. If the cause fits more than one nature of suit, select the most definitive.

VI. Cause of Action. Report the civil statute directly related to the cause of action and give a brief description of the cause.

VII. Requested in Complaint. Class Action. Place an "X" in this box if you are filing a class action under Rule 23, F.R.Cv.P.

Demand. In this space enter the dollar amount (in thousands of dollars) being demanded or indicate other demand such as a preliminary injunction.

Jury Demand. Check the appropriate box to indicate whether or not a jury is being demanded.

VIII. Related Cases. This section of the JS-44 is used to reference related pending cases if any. If there are related pending cases, insert the docket numbers and the corresponding judge names for such cases. Date and Attorney Signature.

Date and Attorney Signature. Date and sign the civil cover sheet.
