C. The parties intend to upgrade the Model 4C to a Leksell Gamma Knife Perfexion which will be equipped with new cobalt-60 (the "Equipment" or "Perfexion") which will be leased by GKF to Medical Center pursuant to the terms and conditions of this Agreement.

Agreement:

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Lease. Subject to and in accordance with the covenants and conditions set forth in this Agreement, GKF hereby leases to Medical Center, and Medical Center hereby leases from GKF, the Equipment. The Equipment to be leased to Medical Center pursuant to this Agreement shall include the latest approved Gamma Knife technology available as of the date of this Agreement, including all hardware and software related thereto as listed in the Specifications.

2. Execution of LGK Agreement by and between Medical Center and Elekta. Medical Center agrees that simultaneously with the execution of this Agreement it shall execute that certain LGK Agreement with Elekta, (hereinafter referred to as the "LGK Agreement"), a copy of which is attached hereto as Exhibit 1 and incorporated herein by this reference.

Exhibit 10.22b

3. Perfexion Upgrade.

3.1 Subject to the terms and conditions set forth below, GKF, at GKF's cost and expense, shall upgrade the Model 4C to the Equipment described in Recital C above (the "Perfexion Upgrade"). GKF shall be responsible for all third party costs related to installation and rigging associated with the Perfexion and de-installation of the Model 4C. In connection with the Perfexion Upgrade, GKF shall also upgrade the flooring and painting in the Medical Center gamma knife suite. In connection with the Perfexion Upgrade, Medical Center, at Medical Center's cost and expense, shall provide GKF with Medical Center personnel (including Medical Center physicists) and services upon request and as required by GKF, among other things, to oversee, supervise and assist with construction and compliance with local, state and federal regulatory requirements and with nuclear regulatory compliance issues and the calibration of the Perfexion, and modification of the Determination of Need, as necessary. Subject to Medical Center's compliance with Section 3.2 below, GKF shall use commercially reasonable efforts to perform the Perfexion Upgrade in the Fall of 2013. The Parties agree that, once the Model 4C is no longer operable due to the commencement of de-installation, GKF will use commercially reasonable efforts to complete the installation and rigging of the Perfexion within six (6) weeks (the “Down Period”) so as to minimize the interruption of Medical Center’s services to its patients. GKF will provide Medical Center with not less than sixty (60) days notice of the approximate dates of the Down Period so that Medical Center can appropriately manage patient scheduling.

3.2 Notwithstanding the foregoing, the Perfexion Upgrade shall be performed by GKF only after all licenses, permits, approvals, consents and authorizations necessary and appropriate for the Perfexion Upgrade, including, without limitation, the proper handling of the cobalt-60 (collectively, the "Permits"), have been obtained by Medical Center at Medical Center's sole cost and expense (other than any filing or registration fees which shall be paid for by GKF). The timing and procedure for such Perfexion Upgrade shall be as mutually agreed upon between the parties. Medical Center represents and warrants to GKF that the Site and shielding in the vault for the Perfexion are compliant with all applicable Nuclear Regulatory Commission and other federal and state requirements.

3.3 GKF confirms and warrants that the Perfexion fits into the existing footprint of the Model 4C, that there is no need for construction at the site (other than minor modifications to be made by GKF as needed), and that Medical Center’s site meets all requirements of the Site Planning Criteria, as that term is used in the purchase agreement between Elekta, Inc. and GKF; provided that, in so warranting, GKF relies upon the warranties and representations made by Medical Center under the Prior Lease and in this Agreement, including without limitation, Section 3.2 above (all of which representations and warranties shall survive and remain in full force and effect).

3.4 Medical Center warrants that it shall utilize its best efforts to fulfill on an expeditious basis its obligations under this Section 3. Medical Center further warrants that it shall on a regular basis keep GKF informed of Medical Center's progress in fulfilling its obligations pursuant to this Section 3.

Exhibit 10.22b

3.5 Upon receipt of Elekta’s report on the results of the Acceptance Tests (as defined in the LGK Agreement), Medical Center shall have three (3) business days to review and validate the results of the Acceptance Tests to confirm that the Perfexion meets the manufacturer’s specifications and documentation. If Medical Center fails to respond within such three (3) business day period, Medical Center shall be deemed to have validated and confirmed the results of the Acceptance Tests.

3.6 It is understood by the parties that GKF is not responsible for any additional upgrades, hardware, cobalt reloading, software changes and/or other modifications to the Perfexion except as expressly set forth herein or otherwise agreed upon in writing by Medical Center and GKF.

3.7 Unless Medical Center notifies GKF at least one hundred eighty (180) days prior to the expiration of the Term that Medical Center wishes to further extend the Term of its Lease Agreement with GKF upon such terms as shall be mutually agreed upon in writing between the parties, GKF shall remove the Perfexion, at its sole expense, within ninety (90) days after the expiration of the Term.

3.8 Notwithstanding anything to the contrary set forth in this Agreement, (i) GKF shall de-install, remove and retain all ownership rights and title to the existing Model 4C; (ii) GKF shall acquire and hold title to the Perfexion; and (iii) Medical Center shall have no ownership interest (or option to purchase any ownership interest) in the Model 4C and/or the Perfexion.

3.9 On the date on which the Model 4C is no longer operable due to the commencement of its de-installation (the “Early Termination Date”), the Prior Lease shall be terminated and of no further force and effect; provided, however, that those provisions of the Prior Lease that are expressly stated or intended to survive termination of the Prior Lease shall survive and remain applicable beyond the Early Termination Date.

4. Additional Services of GKF.

4.1 GKF shall provide maintenance and service of the Equipment as needed for the term of this Agreement to keep the Equipment in a good state of repair, reasonable wear and tear excepted, including but not limited to providing a minimum of two PMI (Preventative Maintenance Inspections) per year and repair work as needed. GKF agrees to exercise due and proper care in the repair and maintenance of the Equipment. GKF shall have the right of access to the Equipment for the purpose of inspecting same at all reasonable times and upon reasonable notice. In the event the Equipment is improperly used by Medical Center or its employees, agents, officers and physicians, GKF may service or repair the same as needed and such expense shall be paid by Medical Center, unless the repair is covered by the Repair Service Agreement, if any, referenced in Section 17, below.

4.2 Use of the calibration phantom system by the Medical Center as requested by the Medical Center, based on availability.

3

Exhibit 10.22b

4.3 Training of Medical Center staff on the proper use of the Equipment (i) at the time of installation of the Perfexion and (ii) at the request of Medical Center for the term of this Agreement, such requests not to exceed more than one request annually;

4.4 Upon the termination of this Agreement, the de-installation and removal of the Perfexion, including any third party costs (but excluding Medical Center costs). Medical Center, at Medical Center's cost and expense, shall provide GKF with Medical Center personnel (including Medical Center physicists) and services upon request and as required by GKF to oversee, supervise and assist with such de-installation and removal.

5. [Intentionally omitted.]

6. Term of the Agreement. The initial term of this Agreement (the "Term") shall commence as of the Effective Date and, unless earlier terminated or extended in accordance with the provisions of this Agreement, shall continue until the date that is six (6) years after the date on which the first procedure using the Perfexion is performed at the Site (the "First Procedure Date"). Medical Center's obligation to make the rental payments to GKF for the Equipment as described in Paragraph 7 below shall commence on the first day of the first full month after the Effective Date of this Agreement. The rental payments described in Paragraph 7 shall apply to the Model 4C until such time as it is upgrade to the Perfexion, and shall then continue to apply to the Perfexion for the duration of the Term of this Agreement.

7. Per Procedure Payments. Medical Center shall pay to GKF the applicable per procedure payment as specified in Exhibit 2 for the use of the Equipment, subject to adjustment as set forth in Sections 7.1(a) and 7.1(b) below. A "procedure" shall be defined as a single patient treatment session using the Equipment provided by GKF pursuant to this Agreement, that may include one or more isocenters during that session. Medical Center shall be billed on the fifteenth (15th) and the last day of each month for the actual number of procedures performed during the first and second half of the month, respectively. Medical Center shall pay for the procedures invoiced within thirty (30) days after being invoiced.

The parties acknowledge that the compensation payable by Medical Center for the Perfexion as set forth in this Agreement has been negotiated by the parties at arm’s length based upon reasonable and jointly derived assumptions regarding the capacity for clinical services available from the Perfexion, Medical Center’s capabilities in providing high quality radiation oncology services, market dynamics, GKF’s risk in providing the Perfexion, and the provision to GKF of a reasonable rate of return on its investment in support of the Perfexion. Based thereon, the parties believe that the rent payments represent fair market value for the use of the Perfexion, the de-installation and removal of the Model 4C, the Perfexion upgrade, maintenance and service, personal property taxes, cost of insurance coverage for the Perfexion, and any other additional services and costs to be provided or paid for by GKF pursuant to this Agreement. Medical Center undertakes no obligation to perform any minimum number of procedures on the Perfexion, and the use of the Perfexion for the performance of procedures is wholly based upon the independent judgment of physicians who order such procedures to meet the medical needs of their patients.

Exhibit 10.22b

(a) If at any time or from time-to-time after the Effective Date, the Medical Center’s Commercial Rate with any "Designated Payor" (excluding those covered in 7(b) below), is increased or decreased such that the new Commercial Rate for such Designated Payor is greater or less than the "Base Commercial Rate" for that Designated Payor (or the then current Commercial Rate if the Non-Medicare Fee Per Procedure rates shown in Exhibit 2 for such Designated Payor have previously been revised pursuant to this subsection) by *, then, (1) Medical Center shall notify GKF thereof in writing (but without disclosing the identity of the Designated Payor) within thirty (30) days of any such increase or decrease and shall provide GKF with reasonably sufficient documentation evidencing the revised Commercial Rate for that Designated Payor (and the amount of the increase or decrease), including, without limitation, copies of the applicable contractual language or fee schedule (with the identity of the Designated Payor redacted), and any remittance advices, EOBs or other documentation showing the payments made to Medical Center by such Designated Payor immediately before and after the subject increase or decrease to its Commercial Rate, it being understood that such documentation may become available following the effective date of such increase or decrease and that Medical Center shall provide such documentation to GKF as and when available; (2) effective in the next billing cycle after said notification (provided that such increase or decrease to the Commercial Rate is then effective), the fee for procedures performed on patients who are assigned to or enrolled with such Designated Payor shall be equal to the Non-Medicare Fee Per Procedure rates as shown in Exhibit 2 (or the then current Non-Medicare Fee Per Procedure rates for such Designated Payor if said Non-Medicare Fee Per Procedure rates have previously been revised pursuant to this subsection), increased or decreased therein by * of the dollar-for-dollar increase or decrease to the Commercial Rate for that Designated Payor; and (3) the Non-Medicare Fee Per Procedure rates set forth in Exhibit 2 for all other Designated Payors shall remain unchanged and in full force and effect. For example, if a Designated Payor’s Commercial Rate decreases by * from the Base Commercial Rate (which, for purposes of this example, is assumed to exceed the * threshold above), then, each Non-Medicare Fee Per Procedure rate shown in Exhibit 2 for that Designated Payor shall be decreased by *.

(b) If at any time or from time-to-time after the Effective Date, the "Medicare Rate" is increased or decreased such that the new Medicare Rate is greater or less than the "Base Medicare Rate" (or the then current Medicare rate if the Medicare Fee Per Procedure rates shown in Exhibit 2 have previously been revised pursuant to this subsection) by * or more, then, (1) Medical Center shall notify GKF thereof in writing within thirty (30) days of any such increase or decrease and shall provide GKF

(c) with reasonably sufficient documentation evidencing the revised Medicare Rate (and the amount of the increase or decrease), including, without limitation, copies of the applicable contractual language or fee schedule (with the identity of the Designated Payor redacted), and any remittance advices, EOBs or other documentation showing the payments made to Medical Center immediately before and after the subject increase or decrease to its Medicare Rate, it being understood that such documentation may become available following the effective date of such increase or decrease and that Medical Center shall provide such documentation to GKF as and when available; (2) effective in the next billing cycle after said notification (provided that such increase or decrease to the revised Medicare Rate is then effective), the fee for procedures performed on Medicare patients shall be equal to the Medicare Fee Per Procedure rates as shown in Exhibit 2 (or the then current Medicare Fee Per Procedure rates if said Medicare Fee Per Procedure rates have previously been revised pursuant to this subsection), increased or decreased therein by * of the dollar-for-dollar increase or decrease to the Medicare Rate. For example, if the Medicare Rate increases by * over the Base Medicare Rate (which, for purposes of this example, is assumed to exceed the * threshold above), then, each Medicare Fee Per Procedure rate shown in Exhibit 2 shall be increased by *.

11.1 Each party shall indemnify, defend and hold harmless the other party, and such other party’s directors, officers, employees, agents and affiliates, from and against any and all claims, actions, liabilities, costs and expenses (including without limitation judgment and settlement costs, court costs and attorneys’ fees) arising out of or relating to negligent or intentional acts or omissions of the indemnifying party or any failure by the indemnifying party to perform any obligation or covenant of the indemnifying party in this Agreement

11.2 Medical Center shall further indemnify GKF for any damage to the Equipment to the extent such damage is caused by the negligent or willfully wrongful acts or omissions of Medical Center or its agents, officers, physicians and employees and are not covered and reimbursed by GKF’s insurance. In the event the Equipment is destroyed or rendered unusable as a result of such negligent or willfully wrongful acts or omissions, this indemnification shall extend up to (but not exceed) the full replacement value of the Equipment at the time of its destruction less salvage value, if any.

11.3 GKF shall further indemnify Medical Center in the event that Medical Center suffers any loss, damage, claim or expense solely as the result of GKF’s breach of its obligations under Section 17, below.

12. Ownership/Title. It is expressly understood that Medical Center shall acquire no right, title or interest in or to the Equipment, other than the right to the possession and use of the same in accordance with the terms of this Agreement.

GKF may at its sole discretion finance the Equipment. Financing may be in the form of an installment loan or a capitalized lease or other commercially available debt instrument. Should GKF finance the Equipment through an installment loan, GKF shall be required to provide the Equipment as collateral against the loan. Should GKF finance the Equipment through a capitalized lease title shall vest with the lessor until GKF exercises its buy-out option. In addition, should GKF finance the Equipment, said agreement may be used as collateral against the loan. No financing by GKF will relieve GKF of its obligations to Medical Center or materially change Medical Center's duties or materially increase the burdens or risks imposed on Medical Center. Medical Center's interest under this Agreement shall be subject and subordinate to the interests of the Lender, which Medical Center shall promptly confirm in writing on Lender's form, if requested by GKF.

15. [Intentionally omitted.]

16. [Intentionally omitted.]

17. Repair Service Agreement. GKF may at its discretion enter into a Repair Service Agreement with Elekta. If GKF has entered into a Repair Service Agreement with Elekta, (a) GKF agrees to fulfill all of its obligations under the Repair Service Agreement and acknowledges that Medical Center is a third party beneficiary of the Repair Service Agreement; (b) GKF will reasonably pursue any and all remedies it may have against Elekta under the Repair Service Agreement, if any, to insure that the Equipment will be in conformity with Elekta's warranties so that it is free from defects in design, materials, workmanship or manufacture which result in noncompliance with the Specifications and/or Elekta's warranties to GKF; provided that, for the avoidance of doubt, none of the foregoing obligations in this Section shall be binding upon GKF if GKF has not entered into a Repair Service Agreement with Elekta.

18. Termination. If, after the initial twenty-four (24) month period following the First Procedure Date or any subsequent 12 month period, the sum of all per procedure payments made by Medical Center to GKF under this Agreement during the most recent twelve (12) month period fell short of *, then and in that event, GKF shall have the option (but not the obligation) of terminating this Agreement upon the giving of written notice to Medical Center of said termination not less than one hundred and eighty (180) days prior to GKF's designated termination date. GKF shall remove the Equipment, at its sole expense, within ninety (90) days after the designated termination date, unless Medical Center notifies GKF within ninety (90) days following receipt of GKF's notice of termination that it wishes to purchase the Equipment in cash at a price to be mutually agreed upon by the parties.

Medical Center shall exercise such option by giving written notice to GKF not less than ninety (90) days prior to the expiration of the initial Term. If Medical Center does not issue such notice, Medical Center shall be deemed to have elected not to exercise such option, and GKF shall remove the Equipment, at its sole cost and expense, within ninety (90) days after the expiration of the initial Term.

9

Exhibit 10.22b

Medical Center shall exercise one (1) of the two (2) options referred to above by mailing an irrevocable written notice thereof to GKF at Four Embarcadero Center, Suite 3700, San Francisco, California, 94111, by registered mail, postmarked on or before the end of the year immediately preceding the expiration of the initial Term of this Agreement. Any such notice shall be sufficient if it states in substance that Medical Center elects to exercise its option and states which of the two (2) options referred to above Medical Center is exercising.

20. No Warranties by GKF with Respect to the Equipment. GKF SUPPLIES THE EQUIPMENT "AS IS" AND 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, DESIGN, CONDITION, DURABILITY, CAPACITY, MATERIAL OR WORKMANSHIP OR AS TO PATENT INFRINGEMENT OR THE LIKE, it being agreed that all such risks as between GKF and Medical Center, shall be borne by Medical Center. Medical Center agrees to look solely to the manufacturer (Elekta) or to suppliers of the Equipment (and its software) for any and all warranty claims with respect to the Equipment. Any and all warranties made by Elekta to GKF will be in its good faith best efforts enforced by GKF on behalf of Medical Center during the initial Term hereof and any renewal Terms.

In any event, Medical Center shall, without further demand, pay to GKF an amount equal to all sums due and payable for all periods up to and including the date on which GKF had declared this Agreement to be in default.

Medical Center agrees that GKF shall have no obligation to sell the Equipment. Medical Center shall in any event remain fully liable for reasonable damages as provided by law for all costs and expenses incurred by GKF on account of such default, including but not limited to, all court costs and reasonable attorneys' fees.

(f) All advertising or promotional materials in which the mark is utilized shall comply with all applicable laws and regulations as well as the standards of proper advertising.

(g) Elekta shall have the right to terminate the license granted in this section with immediate effect if End User violates any provision of this section or utilizes the Mark in any manner which, in the sole opinion of Elekta, presents a reasonable possibility of damage to the Mark.

(h) Upon termination of the license granted by this section, End User shall immediately cease all use of the mark, including, but not limited to, the use permitted under subsection (e) of this section.

(i) Buyer acknowledges that a breach of any of its covenants or agreements hereunder will cause immediate and irreparable harm to Elekta and Elekta Instrument S.A.
