The complaints are similar and allege violations of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, primarily based on the allegation that the underwriters received undisclosed compensation in connection with Primus’ initial public offering. The litigation has been coordinated in the United States District Court for the Southern District of New York with claims against approximately 300 other companies that had initial public offerings during the same general time period. The parties have reached a global settlement of the litigation under which insurance will pay the full amount of the settlement share allocated to Primus, and Primus bears no financial liability. In October 2009, the Court issued an order granting final approval of the settlement. Certain objectors are appealing the final order. While the Company cannot predict the outcome of the litigation, it does not expect any material adverse impact to its business, or the results of its operations, from this matter. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In May 2009, LivePerson, Inc. (“LivePerson”) commenced an action in the United States District Court for the Southern District of New York against InstantService. In the action, LivePerson alleges that InstantService infringes two United States patents held by LivePerson and seeks injunctive relief, damages and attorneys’ fees. In April 2010, InstantService asserted counter-claims against LivePerson, alleging that LivePerson infringes one of InstantService’s patents and is seeking injunctive relief, damages and attorneys fees. In May 2010, the Company joined the action and asserted counter claims against LivePerson, alleging that LivePerson infringes two of its patents and is seeking injunctive relief, damages and attorneys fees against LivePerson. In August 2010, LivePerson added the Company as a defendant to the suit. The Company is investigating the claims made by LivePerson and has reached no conclusion as to the likelihood of an adverse outcome in the litigation, which the Company intends to contest vigorously. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Litigation.
