Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On 2/7/05, Reporting Person was granted 1,800 (target) performance-based restricted stock units (the "2005 PBRSUs") pursuant to Issuer's Amended Long-Term Stock Incentive Plan (the "1996 Plan"). Provided the Issuer's property and casualty operations achieved a specified return on equity for the year 2007 (the "2007 ROE Target") and Reporting Person remains continuously employed by the Issuer until such date, the 2005 PBRSUs vest three years after the grant date. The actual 2005 PBRSU award could be as low as zero, and as high at 150% of the target, based on the return on equity actually achieved. On 2/7/08, the Issuer determined that the 2007 ROE Target had been achieved at a level that entitled holders of 2005 PBRSUs to 150% of their target award. Accordingly, Reporting Person was issued 2,700 shares of common stock.
(2) On 2/14/06, Reporting Person was granted 3,781 (target) performance-based restricted stock units (the "2006 PBRSUs") pursuant to Issuer's 1996 Plan. Provided the Issuer's property and casualty operations achieved a specified average return on equity for the years 2006 and 2007 (the "ROE Target") and Reporting Person remains continuously employed by the Issuer until such date, 50% of the 2006 PBRSUs vest two years after the grant date and the remaining 50% of the 2006 PBRSUs vest three years after the grant date. The actual 2006 PBRSU award could be as low as zero, and as high as 175% of the target, based on the return on equity actually achieved. On 2/7/08, the Issuer determined that the ROE Target had been achieved at a level that entitled holders of the 2006 PBRSUs to 147.25% of their target award. Accordingly, provided Reporting Person remains employed by the Issuer on the applicable vesting dates, Reporting Person will be issued an aggregate of 5,568 shares of common stock.
