(1)	Due to a trading error, the scheduled sale by Nicolas Nierenberg of 120,000 shares of Actuate Corporation was not executed on February 22, 2008, as should have occurred pursuant to the terms of a 10b5-1 trading plan between Mr. Nierenberg and UBS Financial Services Inc. Upon discovery of the error, UBS Financial Services purchased the stock reported in this Form 4 at $5.00 for their own account; the price recieved for the shares was consistent with the 10b5-1 plan's limit order of $5.00 or higher.
