ACCRUAL OF BENEFITS DURING DISABILITY
A SIAC Participant whose employment with the Employer terminates as a result of a Total Disability shall continue to accrue Years of Service and Years of SERP Participation under the Plan for benefit accrual and vesting purposes from the onset of the Total Disability until his Normal Retirement Date or until such SIAC Participants death or cessation of Total Disability, whichever shall first occur, but in no event later than March 31, 2006. Notwithstanding any of the foregoing, no SIAC Participant who has a Total Disability shall accrue a benefit hereunder after March 31, 2006, but may accrue Years of Service and Years of SERP Participation for vesting purposes to the extent provided above.
Such SIAC Participants Final Average Compensation shall not be less than (a) the total base salary paid by the Employer to such SIAC Participant or deferred by such SIAC Participant during the twelve months preceding such SIAC Participants Total Disability, plus, (b) in the case of a SIAC Participant who at any time during his employment with the Employer held the office of Senior Vice President (or a higher office), two-thirds of the average of the annual Incentive Awards paid by the Employer to such SIAC Participant or deferred by such SIAC Participant during the last five annual periods preceding such SIAC Participants Total Disability; provided that the amount of any annual Incentive Award included in computing Final Average Compensation shall not exceed the SIAC Participants base salary for the applicable annual period. Notwithstanding the foregoing, for purposes of computing Final Average Compensation for a SIAC Participant with a Total Disability, only the five highest Incentive Awards paid consecutively in the five annual periods preceding such SIAC Participants Total Disability shall be taken into account. For purposes of this Article V, the phrase five annual periods means (i) the sixty consecutive month period immediately preceding the SIAC Participants Total Disability or (ii) the last five consecutive full calendar years preceding the SIAC Participants Total Disability, whichever period results in the higher benefit. Notwithstanding the foregoing, the Final Average Compensation of a SIAC Participant who is accruing a benefit hereunder as of March 31, 2006 shall be determined as of such date and shall not increase thereafter.
