As used herein:

     (1) For each Procedure that is performed using the Equipment, “Lease Payment” shall be equal to *. For each Procedure using any other equipment or devices, Lease Payment shall be equal to the Technical Component Collections for any other equipment or devices during each such month.

     (2) “Technical Component Collections” means the total amount actually collected by Hospital or its representatives or affiliates during each month from any and all payor sources, including, without limitation, patients, insurance companies, state or federal government programs or any other third party payors, as reimbursement for the technical component of each Procedure, irrespective of whether the Procedure is performed on the Equipment or using any other equipment or devices. The technical fees to be billed for Procedures performed utilizing the Equipment during the Term of this Agreement shall be an amount which is economically justifiable based upon GKF’s direct operating expenses and its total project costs, together with a return thereon. Hospital shall consult and mutually agree with GKF from time to time regarding the amount of the technical fees to be billed by Hospital for Procedures that are performed utilizing the Equipment and any revisions thereto. Subject to compliance with the standard described in the preceding sentence, Hospital and GKF shall mutually agree on the setting or revision of the amount of the technical fees and the acceptance of technical fee component amounts with third party payors prior to their implementation.

     (3) “Cost Component” means the costs incurred by Hospital during the corresponding month for services and personnel associated with the

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.

taxes, in which event the amount paid by GKF shall be immediately payable by Hospital to GKF upon written request; provided that, if GKF is not repaid in full by Hospital within sixty (60) days after GKF’s request therefor, in addition to the repayment of the amounts paid by GKF, Hospital shall pay interest thereon to GKF until paid in full at the annual rate of five percent (5%) in excess of the Federal Reserve Discount Rate then in effect, as published in the Wall Street Journal or similar publication (or the maximum monthly interest rate permitted to be charged by law between an unrelated, commercial borrower and lender, if less) and costs incurred by GKF in collecting such amount from Hospital (other than attorneys’ fees).

     17. No Warranties by GKF. Hospital warrants that as of the First Procedure Date, it shall have (a) thoroughly inspected the Equipment, (b) determined that the Equipment is consistent with the size, design, capacity and manufacture selected by it, and (c) satisfied itself that to the best of its knowledge the Equipment is suitable for Hospital’s intended purposes and is good working order, condition and repair at the time of acceptance. GKF SUPPLIES THE EQUIPMENT UNDER THIS AGREEMENT IN ITS “AS IS” CONDITION. GKF, NOT BEING THE MANUFACTURER OF THE EQUIPMENT OR THE MANUFACTURER’S AGENT, MAKES NO WARRANTY OR REPRESENTATION, EITHER EXPRESSED OR IMPLIED, AS TO THE EQUIPMENT’S MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR USE, DESIGN, CONDITION, DURABILITY, CAPACITY, MATERIAL OR WORKMANSHIP OR AS TO PATENT INFRINGEMENT OR THE LIKE. As between GKF and Hospital, Hospital shall bear all risks with respect to the foregoing warranties. GKF shall not be liable for any direct, indirect and consequential losses or damages suffered by Hospital or by any other person for, and Hospital expressly waives any right to hold GKF liable hereunder for, any claims, demands and liabilities arising out of or in connection with the design or manufacture, possession or operation of the Equipment, including injury to persons or property resulting from the failure of, defective or faulty design, operation, condition, suitability or use of the Equipment. All warranty or other similar claims with respect to the Equipment shall be made by Hospital solely and exclusively against persons other than GKF, including Elekta or any other manufacturers or suppliers. In this regard and with prior written approval of GKF, Hospital may, in GKF’s name, but at Hospital’s sole cost and expense, enforce all warranties, agreements or representations, if any, which may have been made by Elekta or manufacturers, suppliers or other third parties regarding the Equipment to GKF or Hospital. GKF shall not be responsible for the operation of the Equipment, however it shall be GKF’s responsibility that the equipment be properly maintained. GKF and Hospital shall mutually agree to an acceptable delivery date for the Equipment.

     18. Termination for Economic Justification.

          18.1 Following the initial twenty-four (24) months after the First Procedure Date and following each subsequent 12 month period thereafter during the Term, GKF shall have the option to terminate this Agreement if, within a reasonable period of time after GKF’s written request, Hospital does not provide GKF with a reasonable economic justification to continue this Agreement and the provision of Gamma Knife services at the Hospital. GKF’s determination shall be based upon the utilization of the Equipment and other factors considered relevant by GKF in the exercise of its discretion. If GKF elects to terminate pursuant to this Section, GKF shall give written notice thereof to Hospital not less than ninety (90) days prior to the effective date of the termination designated in GKF’s written notice.

          18.2 Notwithstanding the provisions of Section 18.1, if at any time during the Term of this Agreement, Hospital is suspended or terminated from participation in the Medicare program, GKF shall have the option to terminate this Agreement immediately by giving written notice thereof to Hospital.

          18.3 As a result of any termination of this Agreement pursuant to this Section, GKF may enter upon the Site under Hospital supervision and remove the Equipment and any improvements made by GKF to the Site without liability of any kind or nature for appropriate removal or GKF may demand that Hospital remove and return the Equipment and such improvements to GKF, all at GKF’s sole cost and expense. GKF shall restore the Site to a similar pre-deinstallation appearance and condition.

     19. Options to Extend Agreement. As of the end of the Term, Hospital shall have the option either to:

          19.1 Extend the Term of this Agreement for a five (5) year period of time upon the terms and conditions of this Agreement; or

          19.2 Terminate this Agreement as of the expiration of the Term.

Hospital shall exercise one (1) of the two (2) options referred to above by giving an irrevocable written notice thereof to GKF at least twelve (12) months prior to the expiration of the initial Term. Any such notice shall be sufficient if it states in substance that Hospital elects to exercise its option and states which of the two (2) options referred to above Hospital is exercising. If Hospital fails to exercise the option granted herein at least twelve (12) months prior to the expiration of the initial Term, the option shall lapse and this Agreement shall expire as of the end of the initial Term. Further, if Hospital exercises the option to extend the Term and the parties are unable to mutually agree upon the length of the extension of the Term or any other terms or conditions applicable to such extension prior to the expiration of the Term, this Agreement shall expire as of the end of the initial Term.

     20. Events of Default by Hospital and Remedies.

          20.1 The occurrence of any one of the following shall constitute an event of default under this Agreement (an “Event of Default”):

               20.1.1 Hospital fails to pay any Lease Payment when due pursuant to Paragraph 8 above and such failure continues for a period of thirty (30) days after written notice thereof is given by GKF or its assignee to Hospital; however, if Hospital cures the rent payment default within the applicable thirty (30) day period, such default shall not constitute an Event of Default.

               20.1.2 Hospital attempts to remove, sell, transfer, encumber, assign, sublet or part with possession of the Equipment or any items thereof, except as expressly permitted herein.

               20.1.3 Hospital fails to observe or perform any of its covenants, duties or obligations arising under this Agreement or the LGK Agreement and such failure continues for a

period of thirty (30) days after written notice thereof by GKF to Hospital; however, if Hospital cures the default within the applicable thirty (30) day period or if the default reasonably requires more than thirty (30) days to cure, Hospital commences to cure the default during the initial thirty (30) day period and Hospital diligently completes the cure as soon as reasonably possible following the end of the thirty (30) day period, such default shall not constitute an Event of Default.

               20.1.4 Hospital ceases doing business as a going concern, makes an assignment for the benefit of creditors, admits in writing its inability to pay its debts as they become due, files a voluntary petition in bankruptcy, is adjudicated a bankrupt or an insolvent, files a petition seeking for itself any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar arrangement under any present or future statute, law or regulation or files an answer admitting the material allegations of a petition filed against it in any such proceeding, consents to or acquiesces in the appointment of a trustee, receiver, or liquidator of it or of all or any substantial part of its assets or properties, or it or its shareholders shall take any action looking to its dissolution or liquidation.

               20.1.5 Within sixty (60) days after the commencement of any proceedings against Hospital seeking reorganization, arrangement, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, such proceedings shall not have been dismissed, or if within thirty (30) days after the appointment without Hospital’s consent or acquiescence of any trustee, receiver or liquidator of it or of all or any substantial part of its assets and properties, such appointment shall not be vacated.

          20.2 Upon the occurrence of an Event of Default with respect to Hospital, GKF may at its option do any or all of the following:

               20.2.1 By written notice to Hospital, immediately terminate this Agreement as to the Equipment, wherever situated. As a result of the termination, GKF may enter upon the Site and remove the Equipment and any improvements made by GKF to the Site without liability of any kind or nature for so doing or GKF may demand that Hospital remove and return the Equipment and such improvements to GKF, all at Hospital’s sole cost and expense.

               20.2.2 Recover damages from Hospital as may be awarded by a court of competent jurisdiction for the loss of the bargain represented by this Agreement. For purposes of determining such damages, the parties agree that the following methodology shall be used: (a) the amount of such damages shall be equal to the present value of the unpaid estimated future Lease Payments to be made by Hospital to GKF through the end of the Term discounted at the rate of nine percent (9%); and (b) the unpaid estimated future Lease Payments shall be based on the historical trend of payments made by Hospital to GKF hereunder taking into account known factors which could impact the historical trend through the end of the Term. Hospital and GKF acknowledge that the methodology set forth in this Section constitutes a reasonable method to calculate GKF’s damages resulting from an Event of Default under the circumstances existing as of the date of this Agreement. GKF shall use reasonable commercial efforts to mitigate its damages by attempting to sell or lease the Equipment; provided that (i) GKF shall not be obligated to give preference to the sale or lease of the Equipment over the sale, lease or other

disposition of similar equipment or improvements owned or leased by GKF, (ii) GKF shall have no obligation to sell or lease any improvements made by GKF to the Site, and (iii) GKF’s inability in good faith to mitigate damages shall not limit or otherwise affect the foregoing methodology for determining damages as set forth in this Section.

               20.2.3 Sell, dispose of, hold, use or lease the Equipment or any improvements made by GKF to the Site, as GKF in its sole and absolute discretion may determine (and GKF shall not be obligated to give preference to the sale, lease or other disposition of the Equipment or improvements over the sale, lease or other disposition of similar Equipment or improvements owned or leased by GKF).

               20.2.4 Exercise any other right or remedy which may be available to GKF under the Uniform Commercial Code or any other applicable law or proceed by appropriate court action, without affecting GKF’s title or right to possession of the Equipment or improvements, to enforce the terms hereof or to recover damages for the breach hereof or to cancel this Agreement as to the Equipment.

In addition to the foregoing remedies, Hospital shall be liable to GKF for all reasonable costs and expenses incurred by GKF as a result of the Event of Default or the exercise of GKF’s remedies.

          20.3 Upon termination of this Agreement or the exercise of any other rights or remedies under this Agreement or available under applicable law following an Event of Default, Hospital shall, without further request or demand, pay to GKF all Lease Payments and other sums then owing under this Agreement. Hospital shall in any event remain fully liable for all damages as may be provided by law and for all costs and expenses incurred by GKF on account of such default, including but not limited to, all court costs. The rights and remedies afforded GKF under this Agreement shall be deemed cumulative and not exclusive, and shall be in addition to any other rights or remedies to GKF provided by law or in equity.

     21. Removal of Equipment. Upon expiration of the Term, GKF, at its cost and expense, shall remove the Equipment from the Site not more than one hundred (120) days following the last day of the Term; provided that all of GKF’s right, title and interest in and to the improvements made by GKF to the Site pursuant to Section 6 above shall thereupon transfer to Hospital.

     22. Insurance.

          22.1 During the Term, GKF shall, at its cost and expense, purchase and maintain in effect an all risk property and casualty insurance policy covering the Equipment. The all risk property and casualty insurance policy shall be for an amount not less than the replacement cost of the Equipment. The all risk property and casualty insurance policy maintained by GKF shall be evidenced by a certificate of insurance or other reasonable documentation which shall be delivered by GKF to Hospital upon request following the commencement of this Agreement and as of each annual renewal of such policy during the Term.

          22.2 During the Term, Hospital shall, at its cost and expense, purchase and maintain in effect general and professional liability insurance covering the use or operation of the Equipment by Hospital’s employees and agents. The general and professional liability insurance policies shall each provide coverage in amounts not less than One Million Dollars ($1,000,000.00) per occurrence and One and Five Million Dollars ($5,000,000.00) annual aggregate. The policies to be maintained by Hospital hereunder shall be evidenced by a certificate of insurance or other reasonable documentation which shall be delivered by Hospital to GKF no later than the First Procedure Date and as of each annual renewal of such policies during the Term. Hospital shall require any physicians using the equipment to show evidence of professional liability insurance consistent with Hospital’s Medical Staff Bylaws.

          22.3 During the construction of the Site and prior to the First Procedure Date, GKF, at its cost and expense, shall purchase and maintain a general liability insurance policy which conforms with the coverage amounts and other requirements described in Section 22.2 above and which names Hospital as an additional insured party. The policy to be maintained by GKF hereunder shall be evidenced by a certificate of insurance or other reasonable documentation which shall be delivered by GKF to Hospital prior to the commencement of any construction at the Site.

          22.4 During the Term, Hospital shall purchase and maintain all workers compensation insurance to the maximum extent required by applicable law.

     23. Indemnification.

          23.1 Hospital and GKF each hereby covenants and agrees that it will defend, indemnify and hold the other party and the other party’s officers, directors, members, employees and agents at all times harmless from and against any loss, damage and expense (including reasonable attorneys’ fees and other costs of defense) caused by or arising out of: (i) any liability or obligation related to the business of the indemnifying party prior to the date hereof; (ii) any obligation or liability arising from services provided under this Agreement by the indemnifying party to the extent any such liability or obligation directly results from the negligence or intentional misconduct of the indemnifying party, it’s employees or agents ; or (iii) any obligation or liability resulting from a breach of any provision of this Agreement by the indemnifying party, it’s employees or agents. The obligations of the parties under this Section shall survive the expiration or earlier termination of this Agreement.

          23.2 Any party that intends to enforce an indemnity obligation shall give the indemnifying party notice of any claim as soon as possible, but the failure to give such notice shall not constitute a waiver or release of the indemnifying party and shall not affect the rights of the indemnified party to recover under this indemnity, except to the extent the indemnifying party is materially prejudiced thereby. In connection with any claim giving rise to indemnity under this Section resulting from or arising out of any claim or legal proceeding by a person who is not a party to this Agreement, the indemnifying party, at its sole cost and expense, may, upon

written notice to the indemnified party, assume control of the defense of such claim or legal proceeding, to the extent that the indemnifying party admits in writing its indemnification liability to the indemnified party with respect to all material elements thereof. If the indemnifying party assumes the defense of any such claim or legal proceeding, the obligations of the indemnifying party hereunder as to such claim or legal proceeding shall be to take all steps necessary in the defense or settlement thereof and to hold the indemnified party harmless from and against any losses, damages, expenses or liability caused by or arising out of any settlement approved by the indemnifying party and the indemnified party or any judgment in connection with such claim or legal proceeding. Each indemnified party shall cooperate with the indemnifying party in the defense of any such action, the defense of which is assumed by the indemnifying party. Except with the consent of the indemnified party, which consent may be withheld at the indemnified party’s sole discretion, the indemnifying party shall not consent to any settlement or the entry of any judgment arising from any such claim or legal proceeding which, in each case, does not include as an unconditional term thereof the delivery by the claimant or the plaintiff to the indemnified party of a release from all liability in respect thereof. If the indemnifying party does not assume the defense of any claim or litigation, any indemnified party may defend against such claim or litigation in such manner as it may deem appropriate, including but not limited to settling such claim or litigation, after giving notice of the same to the indemnifying party, on such terms as the indemnified party may deem appropriate. The indemnifying party will, promptly after any of the same is incurred, reimburse the indemnified party in accordance with the provisions hereof for all damages, losses, liabilities, costs and expenses incurred by the indemnified party.

          23.3 The indemnity obligations under this Section shall survive the termination of this Agreement with respect to events occurring during or relating to the Term.

     24. Restrictive Covenant.

          24.1 During the Term of this Agreement, neither GKF nor American Shared Radiosurgery Services (“ASRS”) shall, directly or indirectly, within the * of Baptist Health System, own, operate or sell any Gamma Knife system.

          24.2 GKF and ASRS acknowledge that; (i) the terms contained in this Section are necessary for the commercially reasonable and proper protection of the Hospital’s interests; (ii) each and every covenant and restriction contained in this Section is reasonable in respect of such matter, length of time and geographical area; and (iii) the Hospital is relying on the representations of the parties contained in this Section that they shall abide by and be bound by each of the aforesaid covenants and restrictions.

          24.3 If any court or tribunal of competent jurisdiction determines that the duration, geographical limit or any other aspect of the provisions of this Section is unenforceable in accordance with its terms in a particular jurisdiction, the provisions of this Section shall not terminate, but shall be deemed amended to the extent required to render them valid and

enforceable in such jurisdiction and such court or tribunal is hereby authorized and directed to amend this Agreement only to the extent that such court or tribunal determines such an amendment is necessary to make it valid and enforceable in said jurisdiction.

          24.4 Each of GKF and ASRS further agree that damages at law would be an insufficient remedy for the Hospital in the event that any of them violate the provisions of this Section, and that the Hospital shall be entitled to make an application to a court of competent jurisdiction to obtain injunctive relief.

          24.5 The restrictive covenants contained in this Section shall automatically terminate and be of no further force and effect upon the termination of this Agreement for any reason.

     25. Miscellaneous.

          25.1 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Neither party shall assign this Agreement nor any of its respective rights hereunder and Hospital shall not sublease the Equipment without the prior written consent of the other party, which consent shall not be unreasonably withheld.

          25.4 Attorney’s Fees and Costs.
