Incentive Awards

Pursuant to the Plan, the Company granted nonqualified stock options and performance share awards to various officers and other employees effective February 17, 2006. The Plan, a copy of which was filed as Exhibit 10.1 to the Company's Current Report on Form 8-K, filed with the Securities and Exchange Commission on May 27, 2005, is incorporated by reference into this report.

The awards will be reflected in the 2006 Nonqualified Stock Option Agreements and 2006 Performance Share Award Agreements containing the following respective terms:

2006 Nonqualified Stock Option Agreement

Each nonqualified stock option represents the right and option to purchase, on the terms and conditions set forth in the agreement evidencing the grant, ordinary shares of the Company, par value

2




0.15144558 cent per share. The exercise price of the shares subject to the option is $23.65 per share, which as determined by the Plan is based on the arithmetic mean of the high and low prices of the ordinary shares on the grant date as reported by the NYSE. Exercise of options is contingent upon the achievement of specified return on equity ("ROE") targets.

One-third (1/3) of the shares underlying the options will become eligible for vesting upon the later of (i) the date the Company's outside auditors complete the audit of the Company's financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2006, or (ii) the date such ROE is approved by the Board of Directors or an authorized committee thereof, but only if the Company achieves its ROE target for the fiscal year ended December 31, 2006 (the "2006 Option Award"). If the Company fails to reach the ROE target for the 2006 fiscal year, but its actual ROE for such year is not less than 66.67% of the target ROE, then a reduced number of options will become eligible for vesting based on the percentage of target ROE achieved, for example, with 10% vesting at 66.67%. However, no options will become eligible for vesting if the ROE for the 2006 fiscal year is less than (i) 66.67% of the target ROE for such year or (ii) 10% in absolute terms.

Two-thirds (2/3) of the options will become eligible for vesting upon the later of (i) the date the Company's outside auditors complete the audit of the Company's financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such ROE is approved by the Board of Directors or an authorized committee thereof, but only if the Company's actual average annual ROE for the 2006, 2007 and 2008 fiscal years meets or exceeds the average annual ROE target for such period (the "2006-2008 Option Award"). If the Company fails to achieve the average annual ROE target for the 2006, 2007 and 2008 fiscal years, but its actual average ROE for such period is not less than 66.67% of the average annual ROE target, then a reduced number of options will become eligible for vesting based on the percentage of the average annual ROE target achieved, for example, with 10% being eligible for vesting at 66.67%. However, no options will be eligible for vesting for the 2006-2008 Option Award if the actual average annual ROE for the 2006, 2007 and 2008 fiscal years is less than (i) 66.67% of the average annual ROE target for such period or (ii) 10% in absolute terms.

Options which are eligible for vesting, as described above, as part of the 2006 Option Award and the 2006-2008 Option Award will vest and become exercisable upon the later of (i) the date the Company's outside auditors complete the audit of the Company's financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such 2008 ROE is approved by the Board of Directors or an authorized committee thereof, subject to the optionee's continued employment (and lack of notice of resignation or termination) until such date.

Once the options are exercisable, as described above, the optionee may exercise all or any part of the vested portion of their option at any time prior to the earliest to occur of (i) the tenth anniversary of the date of grant, (ii) the first anniversary of the optionee's termination of employment (x) due to death or disability (as defined in the option agreement), (y) by the Company without cause (as defined in the option agreement), or (z) by the optionee with good reason (as defined in the option agreement), (iii) three months following the date of the optionee's termination of employment by the optionee without good reason, or (iv) the date of the optionee's termination of employment by the Company for cause.

Options are exercised by providing written notice specifying the number of shares for which the option is being exercised and the method of payment of the exercise price. Payment of the exercise price may be made in cash (or cash equivalent), in shares, in a combination of cash and shares, or by broker-assisted cashless exercise. The optionee may be required to pay to the Company, and the Company will have the right to withhold, any applicable withholding taxes in respect of the option, its exercise or any payment or transfer under or with respect to the option. Options may not be assigned, sold or otherwise transferred by the optionee other than by will or by the laws of descent and distribution.

2006 Performance Share Award Agreement

Each performance share award represents the right to receive, on the terms and conditions set forth in the agreement evidencing the award, a specified number of ordinary shares of the Company, par value 0.15144558 cent per share. Payment of performance shares is contingent upon the achievement of specified ROE targets.

One-third (1/3) of the performance shares will become eligible for vesting upon the later of (i) the date the Company's outside auditors complete the audit of the Company's financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2006, or (ii) the date such ROE is approved by the Board of Directors or an authorized committee thereof, but only if the Company achieves its ROE target for the fiscal year ended December 31, 2006 (the "2006 Performance Award"). If the Company fails to reach the ROE target for the 2006 fiscal year, but its actual ROE for such year is not less than 66.67% of the target ROE, then a reduced number of performance shares will become eligible for vesting based on the percentage of target ROE achieved, for example, with 10% becoming eligible for vesting at 66.67%. However, no performance shares will become eligible for vesting if the ROE for the 2006 fiscal year is less than (i) 66.67% of the target ROE for such year or (ii) 10% in absolute terms.

Two-thirds (2/3) of the performance shares will become eligible for vesting and payable upon the later of (i) the date the Company's outside auditors complete the audit of the Company's financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such ROE is approved by the Board of Directors or an authorized committee thereof, but only if the Company's actual average annual ROE for the 2006, 2007 and 2008 fiscal years meets or exceeds the average annual ROE target for such period (the "2006-2008 Performance Award"). If the Company fails to achieve the average annual ROE target for the 2006, 2007 and 2008 fiscal years, but its actual average ROE for such period is not less than 66.67% of the average annual ROE target, then a reduced number of performance shares will become eligible for vesting based on the percentage of the average annual ROE target achieved, for example, with 10% becoming eligible for vesting at 66.67%. However, no performance shares will be eligible for vesting for the 2006-2008 Performance Award if the actual average annual ROE for the 2006, 2007 and 2008 fiscal years is less than (i) 66.67% of the average annual ROE target for such period or (ii) 10% in absolute terms.

Performance shares which are eligible for vesting, as described above, as part of the 2006 Performance Award and the 2006-2008 Performance Award will vest upon the later of (i) the date the Company's outside auditors complete the audit of the Company's financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such 2008 ROE is approved by the Board of Directors or an authorized committee thereof, subject to the participant's continued employment (and lack of notice of resignation or termination) until such date.

Payment of vested performance shares will occur as soon as practicable after the date the performance shares become vested. Participants may be required to pay to the Company, and the Company will have the right to withhold, any applicable withholding taxes in respect of the performance shares. Performance shares may not be assigned, sold or otherwise transferred by participants other than by will or by the laws of descent and distribution.
