          8.1 Per Procedure Payments . As rent for the lease of the Equipment to Hospital pursuant to this Agreement, Hospital shall pay to GKF the sum as set forth in Exhibit 8 of this Agreement. (the “Lease Payment”). Hospital shall pay the Lease Payment for each “Procedure” that is completed by the Hospital or its representatives or affiliates at the Site, as defined in Section 5.1, irrespective of whether the Procedure is performed on the Equipment or using any other equipment or devices. As used herein, the term a “Procedure” means any treatment using external, single fraction, conformal radiation, commonly called stereotactic radiosurgery, that may include one or more isocenters during the patient treatment session, delivered to any site(s) superior to the foramen magnum. Hospital’s obligation to make Lease Payments pursuant to this Section shall be expressly limited by Section 8.2, 8.3 and 8.4 hereof.

               If no Procedures are performed by Hospital or any other person utilizing the Equipment or any other equipment devices at the Hospital , Hospital shall not owe any Lease Payment to GKF. GKF shall submit an invoice to Hospital on the fifteenth (15th) and the last day of each calendar month (or portion thereof) for the actual number of Procedures performed during the first and second half of the calendar month, respectively.

For invoices received by the Hospital following the initial three (3) months following the First Procedure Date, the Hospital shall pay invoices within thirty (30) days after submission by GKF to Hospital. All or any portion of an invoice which is not paid in full within forty-five (45) days after submission (with respect to invoices provided after the intial three (3) months following the First Procedure Date) or seventy (75) days after submission (with respect to invoices provided during the initial three (3) months following the First Procedure Date) shall bear interest at the rate of the lesser of one percent (1.0%) per month (or the maximum monthly interest rate permitted to be charged by law between an unrelated, commercial borrower and lender, if less) until the unpaid rent invoice together with all accrued interest thereon is paid in full. If GKF shall at any time accept a Lease Payment from Hospital after it shall become due, such acceptance shall not constitute or be construed as a waiver of any or all of GKF’s rights under this Agreement, including the rights of GKF set forth in Section 20 hereof.

               Within ten (10) days after Hospital’s receipt of written request by GKF, GKF shall have the right to audit Hospital’s books and records (including, without limitation, the books and records pertaining to any other radiosurgery equipment or devices) relating solely to the Hospital’s provision of Procedures to verify the number of Procedures that have been performed by Hospital, and Hospital shall provide GKF with access to such books and records; provided that any patient names or identifiers shall not be disclosed. GKF shall not have access to nor shall it directly or indirectly access any “ Patient Health Information” as such terms are defined by HIPAA. GKF agrees that it shall execute such documents and agreements as may be reasonably required by Hospital to assure compliance with HIPAA.

               In the event a Procedure is not completed due to a technical problem with the Equipment, the Hospital will not be charged a Lease Payment for such Procedure.

          8.2 Adjustment to Lease Payment Due to Increase/Decrease in the Reimbursement Rate.

               (a) If the “Reimbursement Rate” in effect on any “Reset Date” is * less than the “Base Rate” (as such quoted terms are defined in Section 8.2(e) below), Hospital shall inform GKF in writing within ninety (90) days after the applicable Reset Date and shall provide GKF with the information used in calculating such Reimbursement Rate. Within thirty (30) days after GKF’s receipt of such notice, the parties shall meet to renegotiate in good faith the Lease Payments payable by Hospital under this Agreement.

                    In determining the renegotiated Lease Payment, any reduction or increase thereto may or may not be (and is not required to be) in proportion to the reduction to the Reimbursement Rate. Furthermore, any reduction to the Lease Payment will be calculated to provide Hospital with “Operating Income” (as defined below) at a break even level as a result of such reduction (i.e., any reduction shall not exceed the amount required to achieve such “Break Even Level”. The term “Break Even Level” is defined herein as zero dollars ($0) in Operating Income (as defined in Section 8.2(e) hereof) arising from the operation of the Equipment; provided that no Lease Payment reduction shall be imposed that would result in negative Operating Income to GKF in accordance with subsection 8.2(e) below. If the Lease Payment proposed by Hospital would result in negative Operating Income to GKF, then (i) Hospital shall have the recourse to arbitration as provided in Section 8.2(c) below, and (ii) this Agreement shall remain unchanged and in full force and effect until outcome of arbitration, if any.

               (b) Each of GKF and Hospital shall permit the other party and its representatives to inspect its books and records pertaining to the Equipment in order to verify such Operating Income. All HIPAA regulations will be applied in the inspection of Hospital’s books and GKF agrees that it shall execute such documents and agreement as may be reasonably required by Hospital to assure compliance with HIPAA.

               (c ) If the Hospital and GKF are unable to reach an agreement on the new Lease Payment rate, then GKF and Hospital shall within ten (10) days of their failure to reach an agreement in accordance with the last sentence of Section 8.2(a), then GKF and Hospital shall each appoint an arbitrator within ten (10) days of their failure to reach an agreement in accordance with the time frames set forth in Section 8.2(a). Such arbitrators shall appoint a third arbitrator within ten (10) days after their appointment. The arbitrators shall have not less than ten (10) years experience in medical equipment financing, be in good standing with the American Arbitration Association or other comparable organization, and have no prior relationship, attorney/client or otherwise, with any of the parties. The parties shall present all necessary information concerning the dispute to the arbitrators within thirty (30) days following the arbitrator’s appointment. Such arbitrators shall review the information presented by both parties and shall render a decision within thirty (30) days of his of her appointment. The arbitrator’s decision, which shall be made by majority or unanimously, shall be based on a determination of an equitable apportioning of the economic losses resulting to the Hospital as a result of the decrease in the Reimbursement Rate among the Hospital and GKF, and taking into account the capital investment made by the parties. The arbitrators’ decision shall be binding upon the parties and non-appealable. The fees and expenses of the arbitrator shall be shared equally between the parties. The foregoing arbitration procedure shall apply only to disagreements arising from this Section 8.2 and not to any other disputes or disagreements arising from this Agreement.

               (d) If the parties mutually agree on a renegotiated Lease Payment or if a renegotiated Lease Payment is determined by the arbitrator as set forth above, then such renegotiated Lease Payment shall become effective on the date that is three (3) months following the applicable Reset Date, and Exhibit 8.2 hereto shall be deemed automatically amended as of such date.

               (e) As used in this Section 8.2, (i) the “Reimbursement Rate” means the average aggregate technical component reimbursement for Gamma Knife Procedures received by Hospital from all payor sources in effect as of any Reset Date; (ii) the “Base Rate” means the average aggregate technical component reimbursement for Gamma Knife Procedures received by Hospital from all payor sources in effect on the date which is one (1) year after the First Procedure Date ; provided that, if the Lease Payment is renegotiated by the parties at any time or from time-to-time pursuant to this Section 8.2, then, immediately following the implementation of the renegotiated Lease Payment, the Base Rate shall become the Reimbursement Rate in effect as of the Reset Date that immediately precedes the implementation of such renegotiated Lease Payment; (iii) the “Reset Date” means the date which is two (2) years after the First Procedure Date of this Agreement and each annual anniversary date thereafter and (iv) “Operating Income” with respect to either party, means the revenues generated by such party from the Equipment less such party’s corresponding direct operating expenses related to the Equipment, including, without limitation, applicable interest and depreciation expenses on the Equipment and Site improvements, but excluding physician professional fees and direct or indirect administrative overhead expenses.

               (f) If the Lease Payment is reduced at any time or from time-to-time pursuant to this Section 8.2, and thereafter, the Reimbursement Rate in effect on any Reset Date increases by * or more over the then-effective Base Rate, then, for each such increase, the Lease Payment shall also be increased in proportion to the percentage increase in the Reimbursement Rate; provided that in no event shall the increased Lease Payment exceed the Lease Payment in effect on the First Procedure Date.

          8.3 New Technology . Except for Section 8.3(d) below, this Section 8.3 shall only become applicable (i) on or after the date that is * after the First Procedure Date (the “* Year Date”), and (ii) if the average number of Procedures actually performed using the Equipment during the twelve (12) month period immediately preceding the * Year Date was not less than * Procedures (collectively, the “New Technology Preconditions”). If both of the New Technology Preconditions have been satisfied, the following provisions shall apply:

               (a) If at any time on or after the * Year Date, “New Technology” becomes commercially available to perform Procedures which Hospital desires to purchase or lease, Hospital shall, promptly provide written notice thereof to GKF (the “New Technology Notice”).

               (b) If, within ninety (90) days following GKF’s receipt of the New Technology Notice, the parties are unable to agree in good faith on the lease payment or sale price or other material terms for the New Technology, Hospital may lease or purchase the New Technology from any other person or entity; provided that, prior to entering into any lease or purchase agreement with another person or entity for the New Technology, Hospital shall first provide written notice to GKF setting forth the equipment to be used, the amount to be paid, the payment of and (if applicable) the term of such proposal transaction (the “Option Notice”). GKF shall have thirty (30) days following its receipt of the Option Notice (the “Option Period”) within which to agree or decline to lease or sell the New Technology to Hospital on the same terms as

stated in the Option Notice. If GKF agrees to lease or sell the New Technology to Hospital on the same terms as stated in the Option Notice, GKF shall provide written notice of the same to Hospital, and the parties shall promptly enter into a lease or sale of the New Technology on such terms as stated in the Option Notice. If GKF declines to lease or sell the New Technology to Hospital on the terms as stated on the Option Notice, GKF shall provide written notice of, same to Hospital (or, if GKF fails to provide such written notice, GKF shall be deemed to have declined to lease or sell such New Technology) and Hospital shall have one hundred twenty days (120) days following its receipt of GKF’s notice of declination (the “Post-Option Period”) within which to enter into a lease or purchase of the New Technology in accordance with the terms of the Option Notice. Hospital shall provide GKF with a certification of its officer promptly following the full execution of such lease or purchase agreement which certification shall set forth that Hospital has entered into a lease or purchase agreement for the New Technology which lease or purchase agreement contains the terms set forth in the Option Notice, as well as any and all additional terms not noted in the Option Notice and contains no additional substantive terms not stated in the Option Notice. If Hospital does not enter into a lease or purchase agreement for the New Technology containing the terms substantially similar to the terms set forth in the Option Notice within the Post-Option Period, or if any of the terms set forth in the Option Notice are supplemented, deleted, changed or otherwise modified in any way, the process of requiring a new Option Notice, Option Period and Post-Option Period shall be repeated in accordance with the terms set forth in this Section 8.3(b)

               (c) From and after the date on which the Hospital first uses the New Technology, Hospital will not be obligated to pay Lease Payments to GKF for Procedures that are performed on the New Technology. In consideration for the foregoing concession made by GKF, Hospital agrees to guarantee a minimum payment (the “Minimum New Technology Payment”) to GKF for each 365-day period during the Term of this Agreement commencing from and after the date on which the first procedure is performed on the New Technology, the New Technology order date (each such 365-day period is referred to as a “New Technology Payment Period”). The Minimum New Technology Payment shall be equal to the Lease Payment then in effect multiplied by *. Thus, for each New Technology Payment Period, GKF shall be entitled to the greater of: (a) the Lease Payment then in effect, multiplied by the number of Procedures that are performed using the Equipment and any other equipment or devices (other than the New Technology) during such New Technology Payment Period, or (b) the Minimum New Technology Payment (the “New Technology Lease Payment”) . The foregoing shall apply irrespective of whether * Procedures are actually performed using the Equipment during the New Technology Payment Period, and/or whether the New Technology is acquired by Hospital through purchase or lease (from GKF or any other entity). To the extent applicable, within thirty (30) days following the close of each New Technology Payment Period, Hospital shall pay to GKF the shortfall between the Lease Payments made to GKF during such New Technology Payment Period and the Minimum New Technology Payment.
