WHEREAS, Licensee is desirous of obtaining a non-exclusive worldwide license to manufacture and sell certain products embodying and employing the inventions of the aforesaid Letters Patents, and of any reissues or reexaminations thereof; and

WHEREAS, concurrently herewith, the Parties are entering into the License Agreement effective as of the effective date specified therein (the “License Agreement”).

NOW THEREFORE, the Parties hereto, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, agree as follows:

1.5.                              “Licensed Products” means any software, hardware or other product that is owned by Licensee, and that is covered by one or more claims of the Licensed Patents, regardless of whether such product is combined with any Licensee technology or any third party technology, but excluding any CyberKnife System (as defined in the License Agreement) or any other product or component that contains functionality in addition to that required to implement the claims of the Licensed Patents.

2.                                                                                       GRANT OF RIGHTS, SUBLICENSING, RETAINED RIGHTS.

2.1.                              Grant.  Subject to the terms and conditions of this Agreement, Licensor hereby grants to Licensee a non-exclusive, worldwide, non-transferable (except as provided in Section 10.2), perpetual (subject to the provisions of Article 6 hereto), royalty-bearing right and license under the Licensed Patents, with the right to authorize or grant sublicenses (solely as set forth in Section 2.2), to make, have made, use, sell, have sold, offer to sell, market, have marketed, import, export, and otherwise exploit and commercialize the Licensed Products solely in the CyberHeart Field; provided, however, that Licensee agrees not to exercise any rights under the license granted under this Section 2.1, or any rights under this Agreement, prior to the occurrence of a Trigger Event as provided in Section 2.3 of the License Agreement.

2.2.                              Sublicensing.  The license granted in Section 2.1 includes the right for Licensee, without Licensor’s consent, to grant and authorize sublicenses to any Affiliate of Licensee and to customers and final end-users to use only (but no other right other than use) the Licensed Products solely in the CyberHeart Field, on commercially reasonable terms.

2.3                                 Retained Rights; No Other Rights.  Licensor expressly reserves and retains all right, title, and interest in, to, and under Licensed Patents all rights of Licensor not expressly granted to Licensee under this Agreement.  No other rights, licenses, or interest are granted by a Party to the other Party by implication, estoppel, or otherwise, other than as expressly granted by this Agreement.

3.                                                                                       PAYMENTS, AUDITS, REASONABLE EFFORTS.

3.1.                              Royalty.  Within thirty (30) days after the end of each calendar quarter, Licensee shall pay to Licensor a royalty equal to {*****} recognized by Licensee, in accordance

2

with Licensee’s accounting policies and generally accepted accounting principles, from the sale, license, lease, use, or other distribution (“Sale”) of Licensed Products.

3.1.1                        Bundled Products.  In the event that a Licensed Product under this Agreement is sold in a combination package or bundled by or on behalf of Licensee or any Licensee Affiliate with any other products, components or systems that contain functionality in addition to that required to implement the claims of the Licensed Patents (including without limitation, as a component of a system in which other components or products are integrated), then Licensee {*****}, for purposes of determining royalty under Section 3.1, shall be calculated by {*****}.  In the event that {*****}, then {*****}, as det ermined by Licensor in good faith, shall be used in place of {*****}.  For example, if Licensee sells for {*****} a Licensed Product with a {*****} and another product with a {*****}, the Licensee {*****} for purposes of the royalty payable under Section 3.1 would be determined by {*****}.

3.1.2                        Unpriced Products.   In the event that a Licensed Product under this Agreement is provided (other than part of a combination or bundle, which is covered under Section 3.1.1) by or on behalf of Licensee or its Affiliate to any third party receiving below-market or no payment by such third party, then Licensee {*****}, for purposes of determining royalty under Section 3.1, shall be calculated {*****}.

3.2.                              Foreign Sales.  For purposes of computing royalty payments under Section 3.1 based on transactions made in a currency other than United States dollars, royalty payments will be determined in the foreign funds for the country in which the Licensed Products are sold, leased or otherwise distributed and then converted into equivalent United States dollars at the rate of exchange for selling funds as published by the Wall Street Journal (U.S., Western Edition) for the last business day of each quarter.

3.3.                              Audit Rights.  Licensee shall keep or cause to be kept such records as are required to determine, in a manner consistent with Generally Accepted Accounting Principles (GAAP) and this Agreement, the sums due under this Agreement, including, but not limited to, sales of Licensed Products.  At the request (and expense) of Licensor, Licensee and its Affiliates and sublicensees shall permit an independent certified public accountant appointed by Licensor and reasonably acceptable to Licensee, at reasonable times and upon reasonable notice, to examine only those reco rds as may be necessary to determine, with respect to any calendar year ending not more than three (3) calendar years prior to the beginning of the calendar year in which such audit occurs, for records to be kept as provided in this Section 3.3 prior to Licensor’s request, the correctness or completeness of any report or payment made under this Agreement.  Results of any such examination shall be: (a) limited to information relating to Licensed Products; (b) made available to both Parties, and (c) deemed the Confidential Information of Licensee subject to Article 5.  Licensor shall bear the full cost of the performance of any such audit, unless such audit discloses a variance to the detriment of Licensor of more than five percent (5%) of the amount of the original report, royalty or payment calculation.  In such case, Licensee shall bear the full cost of the performance of such audit.

3.4.                              Payment Terms.  All amounts paid hereunder shall be in U.S. dollars.  Licensee shall pay all amounts that have become due and payable hereunder within thirty (30) days of each calendar quarter.  If Licensee fails to make any payment required under this

3

Agreement within thirty (30) days after the date on which such payment becomes due and payable, then Licensor may, at its option and sole discretion and in addition to any other remedies it may have at law or equity, assess a late fee in the amount equal to one percent (1%) of the unpaid balance for each month after payment is due until the invoice is paid in full, or if less, the maximum allowable by law.  For purposes of clarity, failure to make any payment when due pursuant to the terms of this Agreement shall constitute a material breach of this Agreement under Section 6.2, without limiting Licensor’s rights under Section 6.2 or otherwise.

3.5.                              Sole Remuneration.  The payments set out in this Section 3 represent Licensor’s sole remuneration for all rights and licenses granted under this Agreement.

4.                                                                                       INTELLECTUAL PROPERTY OWNERSHIP.

4.1.                              Notification.  Licensee shall promptly notify Licensor in writing (and provide a reasonable description) of any suspected infringement or misappropriation by a third party of any Licensed Patents (a “Third-Party Infringement”), of which it becomes aware.  The obligations under this Section 4.1 do not create any affirmative obligation on the part of one Party to police, review, or otherwise investigate any potential Third Party Infringement.

4.2.                              Enforcement of Licensed Patents.  Licensor shall have the first right, but not the obligation, to file and pursue any suit or action for any third-party infringement of the Licensed Patents.  Licensee agrees to provide reasonable assistance, as may be requested by Licensor, and will reasonably cooperate with Licensor’s enforcement of the Licensed Patents. Licensor shall bear the reasonable expenses incurred by Licensee in providing assistance and cooperation pursuant to this Section 4.2 as requested by Licensor.

4.3.                              Indemnification.  Licensor shall:  (i) at its sole option and expense, defend Licensee, its Affiliates, and their respective agents, employees, and officers (each an “Licensee Indemnitee”) against, or settle, any suit, complaint, demand, or action by a third party against any Licensee Indemnitee arising out of a claim by a third party that one or more claims of an enforceable patent owned by or exclusively licensed to such third party and that issued prior to the date on which the Parties enter into this Agreement, are infringed as a direc t result of Licensee exercising the rights granted to it under Section 2.1 (“Infringement Claim”); and (ii) indemnify each Licensee Indemnitee against any and all damages, cost, expenses, losses, and liabilities, including without limitation reasonable attorneys’ fees, which are awarded in connection with, or which are included in any settlement amounts of, any such Infringement Claim.  Notwithstanding any provision contained herein to the contrary, in no event shall Licensor’s liability under this Section 4.3 exceed the aggregate amount of royalty payments made or to be made by Licensee to Licensor under Section 3.1.  At such time as the liability incurred by Licensor under this Section 4.3 equals at least the aggregate amount of royalty payments theretofore made by Licensee to Licensor under Section 3.1, Licensor’s obligation to indemnify Licensee pursuant to Section 4.3 shall be suspended; provided that, to the extent that Licens ee has then incurred or thereafter incurs damages, costs, expenses, losses and liabilities that are subject to indemnification by Licensor under this Section 4.3 for which Licensee has not been fully indemnified in accordance with the terms of this Section 4.3 (“Indemnifiable Losses”), Licensee may withhold any other royalty payments that are then or that thereafter

4

become payable by Licensee to Licensor pursuant to Section 3.1 and irrevocably offset and credit all such payments against any and all Indemnifiable Losses incurred by Licensee that have not previously been paid or reimbursed by Licensor.

5.                                                                                       CONFIDENTIALITY.

5.1.                              Confidential Information.  “Confidential Information” shall mean any trade secrets, confidential data or other confidential information that is disclosed by one Party (“Disclosing Party”) to the other Party (“Receiving Party”), which: (i) if disclosed in writing, is marked “Confidential,” “Proprietary,” or in some other manner to indicate its confidential nature; (ii) if disclosed orally, is designated as confidential at the time of disclosure and confirmed in writing as confidential wi thin thirty (30) days after its oral disclosure, which confirmation is marked in a manner to indicate its confidential nature and delivered to the Receiving Party within such thirty (30) day period; or (iii) given the contents thereof or circumstances surrounding its disclosure, would reasonably be considered by an objective third party to be the other Party’s Confidential Information.

5.2.                              Exclusions.  Notwithstanding the foregoing, Confidential Information shall not include any information which the Receiving Party can establish: (i) was publicly known or made available in the public domain prior to the time of disclosure by the Disclosing Party; (ii) becomes publicly known or made available after disclosure to the Receiving Party through no action or inaction of the Receiving Party; (iii) is in the possession of the Receiving Party, without confidentiality restrictions, at the time of disclosure by the Disclosing Party as shown by the Receiving Party’s files and records immediately prior to the time of disclosure; (iv) disclosed to the Receiving Party without restriction by a third party who had a right to disclose and was not under an obligation of confidence to the Disclosing Party; or (v) is independently developed by the Receiving Party without use of or reference to the Confidential Information of the Disclosing Party.

5.3.                              Non-Use and Non-Disclosure.  Each Party agrees to use the Confidential Information of the other Party solely for the purposes of exercising its rights or performing its obligations under this Agreement.  Each Party further agrees not to disclose any Confidential Information of the other Party to any third parties other than those third parties who are bound, prior to receiving any Confidential Information, by confidentiality obligations at least as protective as those in this Agreement.

5.4.                              Maintenance of Confidentiality.  Each Party agrees that it shall take reasonable measures to protect the secrecy of and avoid unauthorized disclosure and unauthorized use of the Confidential Information of the other Party.  Without limiting the foregoing, each Party shall take at least those measures that such Party takes to protect its own confidential information of a similar nature, but in no event less than reasonable measures.  Each Party shall reproduce the other Party’s proprietary rights notices on all copies, in the same manner in which such notices were set forth in or on the original.  Each Party shall immediately notify the other Party in the event of any unauthorized use or disclosure of the Confidential Information of the Disclosing Party.

5

5.5.                              Non-Disclosure of Terms.  Each Party agrees not to disclose to any third party the terms of this Agreement (including without limitation all Exhibits) without the prior written consent of the other Party, except to such Party’s attorneys, advisors, investors, potential investors, and others on a need to know basis under circumstances that reasonably ensure the confidentiality thereof, or in connection with financing activities, securities filings, mergers, acquisitions, or the like.

5.6.                              Permitted Disclosures.  Nothing in this Agreement shall be deemed to prohibit the Receiving Party from disclosing any Confidential Information to the extent: (i) required by law; or (ii) pursuant to the written consent of the Disclosing Party; provided, however, that in the event of such requirement, prior to disclosing any Confidential Information, the Receiving Party shall notify the Disclosing Party of the scope and source of such legal requirement and shall, to the extent reasonably possible, give the Disclosing Party the opportunity to challenge the n eed to disclose and/or limit the scope of disclosed information.

6.                                                                                       TERM AND TERMINATION.

6.1.                              Term.  This Agreement shall become effective on the Effective Date and shall remain in effect until the expiration of the last to expire of the Licensed Patents, unless earlier terminated as provided Section 6.2 or Section 6.3 (such period of effectiveness, the “Term”).

6.2.                              Termination for Cause.  Either Party shall have the right to terminate this Agreement following bankruptcy or insolvency of the other party, or any material breach or default in performance under this Agreement by the other Party with sixty (60) days prior written notice to the breaching party specifying the nature of the breach or default.  Unless the breaching party has cured the breach or default prior to the expiration of the sixty (60) day period, the non-breaching party, at its sole option, may terminate this Agreement upon written notice to the breaching party.  Termination of this Agreement shall become effective upon receipt by the breaching party of such second notice.

6.3.                              Effect of Termination or Expiration.  Subject to the provisions of Section 6.6 upon termination of this Agreement by Licensor under Section 6.2 :  (i) the license granted under Section 2.1, and any sublicense granted pursuant to Section 2.2, terminates; (ii) all rights and obligations of each party terminate, except with respect to any rights or obligations that accrued prior to such termination; and (iii) each party shall return to the other party all copies of any and all materials, including any Confidential Information, re ceived by the other Party during the term of this Agreement.  In the event of termination of this Agreement by Licensee, the license granted under Section 2.1 shall become perpetual and royalty-free, and Licensor shall return to Licensee all copies of any materials, including any Confidential Information, received from Licensee during the term of this Agreement.

6.4.                              Effect on Customers.  For avoidance of doubt, no termination or expiration of this Agreement shall be deemed to terminate or otherwise extinguish any rights of any customers of a Licensed Product under their then-current contracts for use of such Licensed Product.

6
