Supplement to Proxy Statement

All page references are to pages in the Proxy Statement, and terms used below, unless otherwise defined, have the meanings set forth in the Proxy Statement.

The disclosure under the heading “Antitrust Matters” is hereby updated by replacing the first full paragraph on page 4 of the Proxy Statement with the following disclosure:

Antitrust Matters  (page  61).  The Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and applicable competition laws in Germany prohibit us from completing the merger until we have furnished certain information and materials to the Antitrust Division of the Department of Justice, the Federal Trade Commission and the German Federal Cartel Office (“FCO”) and the required waiting periods under the HSR Act have expired or been terminated and applicable competition law approvals in Germany have been obtained. BroadSoft and Cisco each filed the requisite notification and report forms with the Federal Trade Commission and the Antitrust Division on November 13, 2017. Cisco withdrew its filing on December 13, 2017, and refiled on December 15, 2017 to provide the antitrust agencies more time to review the transaction. On January 16, 2018, BroadSoft received notice from the Department of Justice and the Federal Trade Commission granting early termination of the waiting period under the HSR Act in connection with the merger. On January 8, 2018, Cisco filed a notice with the FCO in coordination with BroadSoft, and the merger remains subject to either expiration of the waiting period under relevant German competition law or approval by the German FCO. There is no assurance that expiration of the waiting period or approval will be obtained in Germany.

The disclosure under the heading “Antitrust Matters” is hereby updated by replacing the third full paragraph on page 61 of the Proxy Statement with the following disclosure:

Antitrust Matters

Under the HSR Act or any foreign or other antitrust law and the rules that have been promulgated thereunder, certain acquisitions may not be completed until information has been furnished to the Antitrust Division of the U.S. Department of Justice (“DOJ”), to the Federal Trade Commission (“FTC”), or to certain applicable foreign antitrust authorities and applicable HSR Act waiting period requirements have been satisfied, early termination of the HSR Act waiting period has been granted, or the applicable foreign antitrust approvals have been obtained. The merger of BroadSoft with Merger Sub and the conversion of shares of BroadSoft common stock into the right to receive the merger consideration are subject to the provisions of the HSR Act and applicable competition laws in Germany. The merger therefore cannot be completed until the expiration or early termination of the HSR Act waiting period and the receipt of applicable competition law approvals in Germany following the filing of Hart-Scott-Rodino Notification and Report Forms and the applicable competition law filings in Germany by Cisco and BroadSoft. BroadSoft and Cisco each filed the requisite notification and report forms with the FTC and DOJ on November 13, 2017. Cisco withdrew its filing on December 13, 2017, and refiled on December 15, 2017 to provide the antitrust agencies more time to review the transaction. On January 16, 2018, BroadSoft received notice from the Department of Justice and the Federal Trade Commission granting early termination of the waiting period under the HSR Act in connection with the merger. On January 8, 2018, Cisco filed a notice with the FCO in coordination with BroadSoft, and the merger remains subject to either expiration of the waiting period under relevant German competition law or approval by the German Federal Cartel Office. There is no assurance that expiration of the waiting period or approval will be obtained in Germany. The merger agreement provides that each of Cisco and BroadSoft will use its respective reasonable best efforts to obtain all consents and approvals required to be obtained by it for the consummation of the merger, including regulatory clearance. However, if any legal proceeding is instituted or (threatened to be instituted) challenging the merger or the related transactions as violative of any antitrust law, Cisco does not have any obligation to litigate or contest any such legal proceeding or order resulting therefrom and Cisco does not have any obligation to make proposals, execute or carry out agreements or submit to orders providing for (a) the sale, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Cisco or BroadSoft or any of their respective affiliates, (b) the imposition of any limitation or restriction on the ability of Cisco or any of its affiliates to freely conduct their business or, following the closing of the merger, BroadSoft’s business or own such assets or (c) the holding separate of the shares of BroadSoft capital stock or any limitation or regulation on the ability of Cisco or any of its affiliates to exercise full rights of ownership of the shares of BroadSoft capital stock (any of the foregoing, an “Antitrust Restraint”).
