Terms not defined in this Share Agreement shall have the meaning ascribed in the Plan except for the terms “Cause”, “Change in Control”, Disability, and “Good Reason”, which terms shall have the meanings set forth in the Employment Agreement dated as of November 9, 2003 (the “Employment Agreement” between the Corporation and the Employee.

2.	Calculation of Potential Award. The Employee shall be eligible to vest in shares of the Company’s stock as provided in this section (shares that have so vested, “Vested Shares”).
	Employee’s Target Performance Shares: 55,000
	Performance will be measured over the Performance Period using Baseline Year results and Final Year results for the Company as well as for the companies in the Comparator Peer Group (see Appendix A for these defined terms). After the Final Year of the Performance Period, the results of each company in the Comparator Peer Group will be arrayed from highest to lowest. The Company’s results will then be compared to that of the Comparator Peer Group and, based on the Company’s relative position in this array; Vested Shares will be awarded based upon the following formula:

Performance Relative to Peers *	“Earnings Multiple”* multiplied by Target Performance Shares = Vested Shares
Greater Than or Equal to 85th%ile	2 x Target Performance Shares = Vested Shares
Equal to 55th%ile	1 x Target Performance Shares = Vested Shares
Less Than or Equal to 25th%ile	0 x Target Performance Shares = 0 Shares
*Intermediate Performance and resulting Earnings Multiple will be interpolated.

	For example, if the Company’s EPS Compound Annual Growth Rate (CAGR) from fiscal year 2005 to fiscal year 2007 is at the 70th %ile relative to the companies in the S&P500 Healthcare Index, an Earnings Multiple of 1.5 will be applied to the Target Performance Shares to calculate the Vested Shares.
3.	Adjustments to Target Performance Shares: The Target Performance Shares will only be adjusted on a pro rata basis in the event either of the following occur:
	(a)	the Employee’s employment with the Company ends prior to the end of the Performance Period by reason of involuntary termination (other than for Cause) or voluntary termination for Good Reason, the Target Performance Shares will be pro-rated by adding the number of full months

		served by the Employee during the Performance Period plus 24 (but not to exceed the number of months remaining in the Performance Period) and then dividing that total by the number of months in the Performance Period (“Pro Ration Factor”); provided however, that there shall be no pro ration (so that the Pro Ration Factor is 1) if the Employee’s termination of employment occurs within 90 days prior to a Change in Control. At the end of the Performance Period, the Vested Shares will be calculated based on the product of the Target Performance Shares, the Pro Ration Factor and the Earnings Multiple; or
	(b)	the Employee’s employment with the Company is terminated as a result of the non-renewal of the Employment Agreement, the Target Performance Shares will be pro-rated by adding the number of full months served by the Employee during the Performance Period plus 18 (but not to exceed the number of months remaining in the Performance Period) and then dividing that total by the number of months in the Performance Period (“Non Renewal Pro Ration Factor”). At the end of the Performance Period, the Vested Shares will be calculated based on the product of the Target Performance Shares, the Non Renewal Pro Ration Factor and the Earnings Multiple; or
	(c)	If the Employee terminates his employment other than by reason of death or Disability or as contemplated by Section 3(a) or Section 3(b) prior to the end of the Performance Period, the Target Performance Shares will be pro-rated by dividing the number of full months served by the Employee during the Performance Period by the number of months in the Performance Period (“ Voluntary Termination Pro Ration Factor”). At the end of the Performance Period, the Vested Shares will be calculated based on the product of the Target Performance Shares, the Voluntary Termination Pro Ration Factor and the Earnings Multiple.

	(x)	The Employee was terminated for Cause; or

	•	Fiscal Year refers to the year during which the last full month occurs in each company’s annual reporting period. For the Company and most companies in the Comparator Peer Group, the Fiscal Year 2005 ended in December. For certain other companies, the Fiscal Year ended during other months in 2005.
Final Year – Fiscal Year 2008 for the Company and each company in the Comparator Peer Group.
Performance Period – The Performance Period will run from January 1, 2006 through December 31, 2008, the Final Year for the Company (and corresponding Peer Group fiscal years).
Performance Goal(s) - Compound Annual Growth Rate (CAGR) in Fully-Diluted Earnings Per Share for the Company and each company in the Comparator Peer Group from the Baseline Year to the Final Year (i.e., for Fiscal Years 2006, 2007 and 2008).
