Exhibit 10.38

ACCURAY CYBERKNIFE® SILVER ELITE SERVICE AGREEMENT

1.

Scope of Service.    This Silver Elite Service Agreement ("Agreement") is made by and between Accuray Incorporated ("Accuray"), a California corporation, located at 1310 Chesapeake Terrace, Sunnyvale, CA 94089, and                                    ("Customer"), located at                                    , for Accuray to provide planned maintenance service when scheduled by Accuray and corrective maintenance service when requested by Customer to maintain the CyberKnife System installed at Customer's site at                                    ("System") so that it performs substantially in accordance with the Specifications (user Manuals and Reference Guides) defined for the System revision as installed and/or upgraded.

1.1.

Effective Date.    This Agreement shall be effective as of demonstration of acceptance testing by Accuray as described in the CyberKnife Quotation and Purchase Agreement dated                                    , 2005 and signed by the parties, or the expiration of any prior service or warranty agreement, if applicable.

1.2.

Definitions:

1.2.1.

Bug Fix means an error correction or minor change in the existing software and/or hardware configuration that is required in order to enable the existing software and/or hardware configuration to perform to the existing functional specification(s).

1.2.2.

Update means a release of the software or a change to the existing hardware containing substantially only error corrections, minor new features, functionality and/or performance improvements, but that would not be required for the existing software and/or hardware configuration to perform to the existing functional specification(s) of that particular product. Such Update would not necessarily replace or extend the life of the existing software and/or hardware configuration of the product. For example, an Update of software would be indicated where the version number is changed by incrementing the numeric digits to the right of the decimal point, e.g., versions 1.1, 1.2, 1.3, and 1.4 would each be Updates of the software.

1.2.3.

Upgrade/Enhancement means a release of the software or a change to the existing hardware containing major new features, functionality and/or performance improvements that would enable the existing software and/or hardware configuration to perform to the level of the next version of the software and/or hardware configuration and designed to replace the older software and/or hardware version of the same product and/or extend the useful life of that product. For example, an Upgrade/Enhancement of software would be indicated where the version number is changed by incrementing the numeric digits to the left of the decimal point, e.g., versions 1.0, 2.0, 3.0, and 4.0 would each be Upgrades/Enhancements of the software.

1.2.4.

New Version/New Product means a release of the software or a change to the hardware that may or may not work with the existing software and/or hardware configuration, but that in its totality requires, in Accuray's sole opinion, enough change to the software and/or hardware configuration to be considered a New Version or New Product.

1.2.5.

Exclusions means items that are excluded from the definition of Upgrade/Enhancement because of the very nature of the item, as compared to the rest of the components in the system whether in the software and/or hardware configuration, it

1

would cost, in Accuray's sole opinion, more than the average current list price of an Upgrade/Enhancement to an existing product to implement. Examples of such components that are made up of software and/or hardware components that would likely fall into this category are: the linac, the robot, the workstation, the imaging system, the patient couch, and the CyRIS family of products. This exclusion does not mean, however, that portions of such components would not qualify under the definitions of Upgrade/Enhancement, and such items may be offered as an Update/Enhancement at Accuray's sole discretion.

1.2.6.

Consumables means items that are not necessarily part of the CyberKnife system, but are consumed as part of the operation of the CyberKnife system, for example fiducials.

2.

Service Period.

2.1.

The Agreement shall be for an initial period of four (4) years (years 1, 2, 3, & 4) from the Effective Date of this Agreement, including the warranty year, with an optional fifth year. There is no payment required under this Agreement in the first year ("Year 1" or the "Warranty Year"). Customer may elect to receive an additional optional fifth year (the "Optional Year 5") at the price of $260,000 and on terms that are defined below (Section 3.4). Billing will commence on the day following the anniversary of the Effective Date of this Agreement.

2.2.

The Agreement price shall be one of the following, at Customer's option (indicate preferred option):

o

$260,000 per year, paid yearly in advance, for years 2, 3, 4 and Optional Year 5.

o

$68,500 quarterly, paid at the beginning of each quarter, for years 2, 3, 4 and Optional Year 5.

o

$24,000 monthly, paid at the beginning of each month, for years 2, 3, 4 and Optional Year 5.

3.

Equipment to be Covered.    This Agreement is available only for equipment that was purchased directly from Accuray, installed by Accuray engineers and has not been moved from its original installation location or disconnected from its original power supply without written permission or direction from Accuray. The Agreement must immediately commence at the expiration of the factory warranty period or prior service agreement. In the event of lapse of service, Customer shall have the right to reinstate such service by payment of the current service fee for the then-current service period in addition to the reasonable costs for Accuray to inspect, repair, and return the System to the state at which the System would have been had a service agreement been in force continuously since the expiration of the System factory warranty.

4.

Software Maintenance (Bug Fixes and Updates)

4.1.

For the duration of this Agreement, Accuray will provide software Updates and Bug Fixes for software that is included as a part of the CyberKnife System. These Updates and Bug Fixes may be transmitted electronically to Customer for subsequent installation by Customer technicians. Corrections of significant complexity, however, may be installed by Accuray service engineers. Software maintenance will be included only for those product features that were originally purchased with the System or subsequently purchased by Customer from Accuray as a System Upgrade/Enhancement.

4.2.

Customer is not entitled to any Upgrades/Enhancements or New Version/New Products under this Agreement. Customer may purchase Upgrades/Enhancements and New Version/

2

New Products separately, and such Upgrades/Enhancements or New Version/New Products will then be maintained in accordance with the terms of this Agreement.

4.3.

During the service periods, Accuray shall provide Customer with any and all applicable product notices regarding maintenance, support, Upgrades/Enhancements, Updates and Bug Fixes generally circulated by Accuray to Accuray Customers with CyberKnife installations.



4.4.

All such Updates and Bug Fixes, when made by Accuray or according to Accuray instructions or the product notice, shall be considered to be done by and under the direction of Accuray.

5.

System Quality Assurance Testing

5.1.

The maintenance and support services provided by Accuray under this Agreement do not include any System Quality Assurance Testing ("QA"). System commissioning and QA are the sole responsibility of Customer, and Customer is advised to perform QA on a regular and ongoing basis. In addition, Customer is required to maintain up-to-date QA logs. If Customer fails to perform the appropriate QA of the System, and to record such QA in the appropriate logs, Accuray, upon giving Notice to Customer in accordance with Section 11 of this Agreement, reserves the right to terminate this Agreement.

5.2.

Prior to performing any scheduled service or preventive maintenance on the System, Accuray will review Customer's QA logs, and if such logs are not up-to-date, Accuray may refuse to service the System. In the event that the requested service is necessary to bring the System to a point where QA can be performed, Accuray will proceed with the service only after Customer signs a written acknowledgement that QA is Customer's sole responsibility and that appropriate QA will be performed prior to conducting any patient treatments.

6.

Service Coverage Period

6.1.

The Service Coverage Period will be the hours of 8:00 AM to 9:00 PM local time Monday through Saturday (excluding Federal holidays). Customer has the option to request service during non-normal hours, in which case Customer shall pay the overtime premium portion of the non-normal hours worked. (Non-normal hourly rate minus normal hourly rate.) Accuray shall provide Customer with contact points to request service on a 24-hours-a-day, 7-days-a-week ("24/7") basis. Accuray, directly or remotely as the situation requires, either with its own personnel or through contractors, shall initially respond within one (1) hour of receipt of a call for service. The initial response shall include telephone support, including (as applicable) consultations, diagnostic assistance and advice on the use and maintenance of the System.

6.2.

Customer will promptly notify Accuray, by calling Accuray's Customer Support Line at 1-877-668-8667, of any problem or defect with the System and, at no charge, provide Accuray service engineers access to the System and use of adequate facilities and equipment at mutually agreeable times as necessary for Accuray to perform the service. Customer shall have as many service calls as are reasonably needed to maintain the System so that it performs substantially in accordance with the Specifications during the period of this Agreement.

6.3.

Use of the facility CT scanner may be required for testing purposes and shall be scheduled to allow as expeditious completion of service as is reasonably possible. Facility staff will operate the CT scanner. If service is unreasonably delayed and Accuray service engineers are required to remain on site, Accuray may choose to charge the current hourly service rates for the duration of the delay period.

3

6.4.

Accuray will perform System planned maintenance as prescribed in the current System maintenance manuals. Planned service will be scheduled at least two (2) weeks in advance and will be performed at a mutually agreed-upon time. Upon completion of a service or preventive maintenance call, Accuray shall leave Customer a copy of a service report describing the service or maintenance performed.



6.5.

To the extent that they become available during the term of this Agreement, Customer will be entitled to the benefits of remote diagnostic capabilities used by Accuray support engineers. This may require Customer to modify their telecommunications infrastructure to take advantage of this capability. This would be at Customer expense.

7.

Uptime

7.1.

Uptime/Downtime.    Uptime shall mean any time that the System is not down ("Uptime"). A down System means that a patient cannot be treated due to an actual malfunction of the System and that the System is immediately available for an Accuray service engineer to work on it ("Downtime").

7.2.

Guarantee.    Accuray will guarantee that the System shall have an Uptime percentage of at least 98% of normal treatment hours on an annual basis during the Term of this Agreement. Normal treatment hours shall be from 8:00 AM to 5:00 PM local time Monday through Friday (excluding Federal holidays). The first 12-month period will start as of the Effective Date of this Agreement.

7.3.

Calculation.    Downtime will be calculated from the time a down System call is received by Accuray to the time of repair, counting normal treatment hours. The System will be calculated as up when the System repair has been completed and the System is available for treatment during normal treatment hours, whether or not patients are scheduled for treatment. Scheduled preventive maintenance, System upgrades, and time that the System is unavailable as a result of something beyond Accuray's control, including without limitation (i) Customer's use of the System for purposes other than its intended and authorized purposes, (ii) the negligence of Customer, (iii) the failure of Customer to operate the System in accordance with the User Manuals, (iv) use by untrained operators, (v) e-Stops, power outages or the like or (vi) the negligence of any party other than Accuray, will be calculated as Uptime.

7.4.

Reports.    Customer is responsible for recording and reporting Downtime to Accuray. Reports for the previous month's Downtime shall be provided to Accuray on or before the 15^th day of each month.

7.5.

Failure to Meet Guarantee.    For each year of the term of this Agreement, if Accuray achieves a 12-month uptime average of 90-97.9%, the Agreement period will be extended one (1) week for every percentage point or fraction thereof below 98%.

8.

Replacement Parts

8.1.

Accuray shall make a commercially reasonable effort to supply at the time of need or stock at Customer's facility all tools, equipment, replacement parts and Consumables as would reasonably be required by Accuray to perform the required repairs and return the System to good working order. Accuray shall make a commercially reasonable effort to maintain at its factory or service center(s) a stock of spare parts, including, in particular, long-procurement-lead-time parts.

8.2.

Replacement parts used under this Agreement may be either new manufacture or factory refurbished at Accuray's choice. All replacement parts and assemblies provided will be manufactured in accordance with Accuray's quality system, and any applicable laws and

4

regulations. Parts replaced under this Agreement become the property of Accuray and will be disposed of by Accuray Field Service engineers. Notwithstanding the foregoing, all parts that are considered by local regulation to be "hazardous" or "contaminated" waste, or material that requires "special handling" will be disposed of or retained by Customer at Customer's facility.

9.

Exceptions

9.1.

All obligations of Accuray under this Agreement shall be suspended and/or cease in the event of:

9.1.1.

The intentional abuse of the System or negligence by Customer.

Use of the System for other than its intended and authorized purposes, or in a manner not consistent with Accuray's User Manuals, including maintenance of the necessary operating environment and line current conditions, and the failure of Customer to cure such matter within thirty (30) days of actual written notice thereof from Accuray.

9.1.5.

Failure to make payments in accordance with the payment schedule set forth above in Section 2.2.

9.2.

If corrective action or adjustment of the System is performed by Customer's staff at the direction of Accuray, such action or adjustment shall not reduce Accuray's responsibility under this Agreement or liability for the performance of the System.

10.

Cancellation Penalty.    Customer shall have the right to cancel and terminate this Agreement, with or without cause, at any time upon thirty (30) days' prior written notice to Accuray. There shall be no penalty for such cancellation and termination.

11.

Breach.    Either party reserves the right to cancel this Agreement by written notice upon the breach of the other. An event of breach may include, but is not limited to, failure to make payment due under this Agreement, failure to provide access as required to execute the services contemplated by this Agreement, failure to perform and log QA, or the filing of notice under Federal bankruptcy laws. If the breaching party is unable or unwilling to cure or make a good faith effort to cure such breach within thirty (30) days of actual written notice the other shall be relieved of all obligations under this Agreement and may terminate. Termination shall not be the terminating party's exclusive remedy, and the terminating party shall retain all other available legal and equitable remedies.

12.

Limitation of Liability and Warranty

12.1.

If it is determined in accordance with applicable law that any fault or neglect of either party, its employees or agents, substantially contributes to damage or injury to third parties, such party shall be responsible in such proportion as reflects its relative fault therefore, and shall hold the other party harmless from any liability or damages arising out of such fault or neglect. Accuray's liability arising under this Agreement shall be limited to an amount not to exceed the payment(s) received by Accuray for the then current Agreement year. In addition, Accuray shall not be liable to Customer in the event that Customer's or any third party's acts or omissions contributed in any way to any loss it sustained or the loss or

5

damage is due to an act of God or other causes beyond its reasonable control. IN NO EVENT WILL ACCURAY BE LIABLE TO CUSTOMER FOR ANY LOST PROFITS, LOST SAVINGS, LOST REVENUES OR DOWNTIME, SPECIAL, INDIRECT, INCIDENTAL DAMAGES OR OTHER CONSEQUENTIAL DAMAGES ARISING OUT OF OR IN CONNECTION WITH THE AGREEMENT OR THE USE OR PERFORMANCE OF THE SYSTEM.
