     The information in the Offer to Purchase and the Letter of Transmittal is incorporated into this Amendment by reference to all of the applicable items in the Schedule TO, except that such information is hereby amended and supplemented to the extent provided herein. Capitalized terms used but not defined herein have the meanings ascribed to them in the Schedule TO and the Offer to Purchase.

Item 11. Additional Information.

Item 11 of the Schedule TO is hereby amended and supplemented by adding the following text thereto:

     “The Offer expired at 12:00 midnight, New York City time, on Wednesday, June 8, 2011. Wells Fargo Bank, N.A., the Depositary for the Offer has advised Purchaser that, as of such time, a total of 14,711,891 Shares had been validly tendered and not withdrawn in the Offer, with an additional 376,057 Shares tendered by notice of guaranteed delivery. The tendered Shares (excluding shares tendered subject to guaranteed delivery procedures) represent approximately 84% of the outstanding Shares not owned by CNA Financial and its subsidiaries. The number of Shares tendered pursuant to the Offer satisfies the non-waivable “majority-of-minority” condition to the Offer. Purchaser has accepted for payment all Shares that were validly tendered in the Offer, and payment for such Shares will be made promptly in accordance with the terms of the Offer. Upon purchase of the tendered Shares, CNA Financial and its subsidiaries will own approximately 94% of the outstanding Shares.

     As soon as practicable, Purchaser intends to complete a short-form merger with and into CNA Surety. No vote of CNA Surety stockholders will be required in connection with the merger. As a result of the merger, all shares of CNA Surety common stock held by the remaining minority stockholders of CNA Surety will be cancelled and, subject to appraisal rights under Delaware law, converted into the right to receive $26.55 per share in cash, the same consideration paid in the tender offer. Following the completion of the merger, CNA Surety will be a wholly owned indirect subsidiary of CNA Financial and CNA Surety’s common stock will cease to be traded on the New York Stock Exchange.

     On June 9, 2011, CNA Financial issued a press release announcing the expiration and results of the Offer. The full text of the press release is attached hereto as Exhibit (a)(5)((iii)) and is incorporated herein by reference.”
