Other than the agreements and transactions described under the heading “Management” and the transactions described below, since January 1, 2005, there have not been, and there is not currently proposed, any transaction or series of similar transactions pursuant to which we were or will be a party in which the amount involved exceeded or will exceed $60,000 and in which any director, executive officer, holder of 5% or more of any class of our capital stock or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest.

In May 2005, we acquired Avivo Corporation, which was doing business as Atomz, a provider of on-demand website search and web content management, in exchange for approximately $4.2 million in cash, 2,958,713 shares of common stock and 164,434 options to purchase our common stock. Of this consideration, Mr. Kusmer, who at the time was the chief executive officer and a significant stockholder of Avivo and who is now one of our senior vice presidents and the general manager of our search and content solutions business unit, received approximately $316,000 in cash and 231,730 shares of our common stock.

In February 2006, we acquired Visual Sciences, LLC in exchange for $22.0 million in cash, 568,512 shares of common stock, warrants to purchase 1,082,923 shares of common stock, which expire on August 1, 2007 and have an exercise price of $18.4685 per share, and $20.0 million in aggregate principal amount of unsecured senior notes. Of this consideration, Mr. MacIntyre, who at the time was the chief executive officer and a significant member of Visual Sciences and who is now the chief executive officer of our Visual Sciences business unit, received approximately $5.4 million in cash, 161,749 shares of common stock, which are being held in escrow until April 1, 2007 to satisfy possible indemnification claims we may bring against Visual Sciences, a warrant to purchase 308,095 shares of common stock and an unsecured senior note in the approximate principal amount of $5.7 million.

We have entered into indemnification agreements with each of our executive officers and directors. Those indemnification agreements require us to indemnify these individuals to the fullest extent permitted by Delaware law. In addition, we have purchased a policy of directors’ and officers’ liability insurance that insures our directors and officers against the cost of defense, settlement or payment of a judgment in some circumstances.
