Item 2.01 Completion of Acquisition or Disposition of Assets.

On November 21, 2011, pursuant to the terms of the previously announced Agreement and Plan of Merger, dated October 10, 2011 (the “Merger Agreement”), among ARRIS Group, Inc., a Delaware corporation (“Parent”), Amsterdam Acquisition Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Purchaser”), and BigBand Networks Inc., a Delaware Corporation (“BigBand”), Purchaser was merged with and into BigBand, with BigBand continuing as the surviving corporation and a wholly owned subsidiary of Parent.

As previously announced, pursuant to the terms of the Merger Agreement, Purchaser commenced a cash tender offer (the “Offer”) to acquire all of the issued and outstanding shares of BigBand’s common stock, par value $0.001 per share (the “Shares”), for $2.24 per Share in cash, without interest and less any applicable withholding taxes (the “Offer Price”), upon the terms and subject to the conditions set forth in the Offer to Purchase, dated October 21, 2011 (the “Offer to Purchase”), as amended on November 14, 2011, and as further amended on November 18, 2011 (“Amendment No. 2”), and in the related Letter of Transmittal (the “Letter of Transmittal”). Copies of the Offer to Purchase and Letter of Transmittal were filed as Exhibits (a)(1)(A) and (a)(1)(B), respectively, to the Schedule TO filed with the SEC on October 21, 2011.

The Offer expired at midnight, New York City time, on Friday, November 18, 2011. According to American Stock Transfer & Trust Company, LLC, the depositary for the Offer, as of the expiration time, an aggregate of 67,103,577 Shares (including approximately 728,324 Shares delivered through notices of guaranteed delivery) were validly tendered and not properly withdrawn, representing approximately 92.5% of the total outstanding Shares on a diluted basis including shares underlying options to purchase shares of BigBand common stock that were then exercisable and had an exercise price less than the Offer Price. Purchaser accepted all of the Shares that were validly tendered and not properly withdrawn for payment pursuant to the terms of the Offer.

Pursuant to the terms of the Merger Agreement, on November 21, 2011, Purchaser effected a “short form” merger under Section 253 of the Delaware General Corporation Law (“DGCL”), pursuant to which Purchaser merged with and into BigBand, with BigBand as the surviving corporation (the “Merger”). As a result of the Merger, Shares that were not tendered in the Offer (other than Shares owned by Parent, Purchaser or BigBand, or any of their respective wholly owned subsidiaries, or Shares that were held by stockholders who properly and validly perfected their appraisal rights under DGCL) were converted into the right to receive an amount equal to the Offer Price. As a result of the Merger, BigBand became a wholly owned subsidiary of Parent.

Purchaser’s acquisition of the Shares in the Offer and the Merger was funded through Parent’s existing working capital.

On November 21, 2011, Parent issued a press release announcing the expiration and completion of the Offer and its intention to complete the Merger. The full text of the press release was filed as Exhibit (a)(1)(J) to Amendment No. 2.
