(4) Loews Corporation holds none of the shares directly and specifically disclaims beneficial ownership of the securities identified herein. Includes 27,425,147 shares owned directly or indirectly by Continental Casualty Company prior to the completion of the tender offer made by Surety Acquisition Corporation and 14,711,891 shares tendered pursuant to such tender offer, which tender offer expired at midnight, New York City time, on June 8, 2011. On June 10, 2011, Surety Acquisition Corporation was merged with and into CNA Surety Corporation in accordance with the previously announced merger agreement and CNA Surety Corporation became a wholly owned subsidiary of the Continental Casualty Corporation. The characterization of shared dispositive power with the parent company is made solely as a consequence of SEC interpretations regarding control of the subsidiaries.

This Amendment No. 4 amends the statement on Schedule 13D (the “Schedule 13D”) filed with the Securities and Exchange Commission (“SEC”) on March 27, 2000 by Continental Casualty Company, an Illinois insurance company (“Continental”), CNA Financial Corporation, a Delaware corporation (“CNAF”), and Loews Corporation, a Delaware corporation (“Loews”), as amended by Amendment No. 1 filed on May 31, 2000, Amendment No. 2 filed on November 1, 2010 and Amendment No. 3 filed on April 21, 2011. Capitalized terms used but not defined herein shall have the meanings ascribed to them on the Schedule 13D, as amended.

Item 4. Purpose of Transaction.

Item 4 of Schedule 13D is hereby amended by inserting the following at the end thereof:

“Surety Acquisition Corporation (“Merger Sub”), a direct subsidiary of Continental, has accepted for payment and paid for all of the Shares of CNA Surety validly tendered and not withdrawn in response to the previously announced Offer. The Offer expired at 12:00 midnight, New York City time, on Wednesday, June 8, 2011.

On June 10, 2011, CNAF caused a short-form merger (the “Merger”) pursuant to §253 of the General Corporation Law of the State of Delaware (“DGCL”), pursuant to which Merger Sub, merged with and into CNA Surety, with CNA Surety continuing as the surviving corporation. The Merger was consummated in accordance with the terms of the previously announced Merger Agreement. As a result of the Merger, all of the Shares held by the stockholders of CNA Surety, other than Shares held by CNAF and its subsidiaries, were cancelled and, subject to appraisal rights under Delaware law, converted into the right to receive $26.55 per share in cash, without interest and subject to any applicable withholding of taxes (the “Merger Consideration”). As a result of the Merger, CNA Surety is now a wholly-owned subsidiary of Continental.

As a result of the Merger, the New York Stock Exchange (“NYSE”) suspended trading in the Shares prior to the open of trading on June 13, 2011 and filed a Form 25 with the Securities and Exchange Commission (the “SEC”) to withdraw the Shares from listing on the NYSE and from registration under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In addition, CNA Surety will file a Form 15 with the SEC to terminate registration of the Shares under the Exchange Act.

In accordance with the terms of the Merger Agreement, at the effective time of the Merger, the directors of Merger Sub, Thomas F. Motamed, D. Craig Mense, Larry A. Haefner, Jonathan D. Kantor and Thomas Pontarelli became the directors of CNA Surety.”
