Exhibit 8

PURCHASED SERVICES PAYMENTS

Annual Paid Procedures Performed	Percentage of Technical Component Collections Payable To GKF For Each Procedure
[*****]	[*****]
[*****]	[*****]

Notwithstanding anything to the contrary set forth herein, for purposes of determining the Purchased Services Payments, the number of annual Procedures performed shall be reset to zero (0) at the commencement of each anniversary of the First Procedure Date after the Icon Upgrade and Reload has been completed.

For Procedure count purposes, any patient treatment provided on a fractionated basis shall count as one (1) Procedure. Charity cases shall not be included in the annual Procedures performed count.

Charity Cases

As a means to support Medical Center’s mission of providing charity care for persons who require Gamma Knife procedures who are not covered by Medicare, Medicaid, TriCare, Ohio’s Hospital Care Assurance Program, or private insurance programs (whether indemnity, preferred provider, health maintenance organization, etc.) and who do not have the means to pay for such procedures based on Medical Centers adopted standards of indigency, GKF agrees that Medical Center may perform Procedures on a charity or unreimbursed basis so long as no such charity or unreimbursed Procedures are counted towards the number of annual paid Procedures performed for purposes of determining the Purchased Services Payments due hereunder. Medical Center shall be solely responsible (and GKF shall not in any manner be or become responsible) for determining whether any person meets the standards of indigency. Medical Center shall provide reasonable written documentation evidencing satisfaction of the conditions set forth herein to GKF at or prior to the expected time of treatment.
