Actuate Commences $60 Million Dutch Auction Tender Offer

San Mateo, California — Actuate Corporation (NASDAQ: ACTU), the leader in delivering Rich Internet Applications Without Limits™, announced its intention to commence a “modified Dutch auction” tender offer to purchase for cash up to a maximum of $60 million worth of its common stock, par value $0.001 per share, at a price per share not less than $3.15 and not greater than $3.40. Actuate Corporation intends to commence the stock tender offer today, November 5, 2008, and expects the stock tender offer to expire at 5:00 p.m. New York City time on December 5, 2008, unless extended. The maximum number of shares proposed to be purchased in the stock tender offer represents approximately 31.29% percent of Actuate’s currently outstanding common stock. Actuate Corporation plans to fund this tender offer with $60 million of cash, of which approximately $30 million will be from the net proceeds to us from a credit facility and of which approximately $30 million will be from cash on hand.

Jefferies & Company, Inc. will serve as the dealer manager for the stock tender offer; D.F. King & Co., Inc. will serve as the information agent; and Computershare, Inc. will serve as the depositary.

Pete Cittadini, President and Chief Executive Officer, commented: “The Board believes that this offer is an opportunity to increase the long-term value of our stock for our stockholders, while at the same time providing stockholders who wish to tender some or all of their shares a way to do so efficiently.”

A “modified Dutch auction” allows stockholders to indicate how many shares and at what price within Actuate Corporation’s specified range they wish to tender. Based on the number of shares tendered and the price specified by the tendering stockholders, Actuate Corporation will determine the lowest price per share within the range that will enable it to purchase $60 million worth of its shares, or such lesser dollar value of shares as are properly tendered. At the minimum price of $3.15 per share, Actuate Corporation would purchase a maximum of 19,047,619 shares, while at the maximum price of $3.40 per share, Actuate Corporation would purchase a maximum of 17,647,058 shares. Actuate Corporation will not purchase shares below a price stipulated by a stockholder, and in some cases, may actually purchase shares at prices above a stockholder’s indication under the terms of the “modified Dutch auction.” The stock tender offer is not contingent upon a minimum number of shares being tendered but is conditioned on a number of events as described in the offer to purchase. Specific instructions and a complete explanation of the terms and conditions of the stock tender offer are contained in the Offer to Purchase and related materials that will be mailed to stockholders of record as of October 31, 2008 beginning on November 5, 2008.

Actuate Corporation’s executive management team and its board of directions are not participating in the tender offer.

Neither of Actuate Corporation’s management, nor any of its board of directors, executive officers, the dealer manager, the information agent or the depositary is making any recommendation to stockholders as to whether to tender or refrain from tendering their shares in the stock tender offer. Stockholders must decide how many shares they will tender, if any, and the price within the stated range at which they will tender their shares. Stockholders should consult their financial and tax advisors in making this decision.
