Each New Project Interest will be documented in the organizational documents (for each New Project Entity, the “New Project Entity Organizational Documents”) of a new entity (for each New Project, the “New Projects Entity”) formed to own such New Project. Seller will acquire the New Project Interest pursuant to a purchase agreement customary for transactions of a similar nature, which purchase agreement shall include customary representations and warranties of Seller for such a transaction.  Seller will also be party to such other ancillary documents of the New Project Entities as reasonably determined by Buyer at the time of formation of such New Project Entities.

(b)           The New Project Entity Organizational Documents of each New Project Entity shall (i) grant Seller pre-emptive rights (subject to customary carve-outs) with respect to future equity issuances by such New Project Entity to maintain the proportionate ownership interest represented by Seller’s initial Capital Interest in such New Project Entity, (ii) grant Seller customary tag-along rights with respect to future sales of equity interests in such New Project Entities by Buyer and (iii) provide that the New Projects Interest is not transferable by Seller without Buyer’s consent (other than for estate planning purposes).

8.6           Notice and Opportunity to Defend. If any Party (the “Indemnitee”) receives notice of any claim or the commencement of any action or proceeding with respect to which any other Party is obligated to provide indemnification (the “Indemnifying Party”) pursuant to Section 8.1 or 8.2, the Indemnitee shall promptly, (and in any event within five (5) Business Days after receiving notice of the claim) give the Indemnifying Party notice thereof; provided, however, that the failure to deliver such notice shall not be a condition precedent to any liability of the Indemnifying Party under the provisions for indemnification contained in this Agreement except to the extent the failure to deliver such notice prejudices the Indemnifying Party’s ability to defend such proceeding.  The Indemnifying Party may assume control of such defense; provided, that prior to the Indemnifying Party assuming control of such defense, it shall (x) demonstrate to the Indemnitee in writing such Indemnifying Party’s financial ability to provide full indemnification to the Indemnitee with respect to such proceeding (including the ability to post any bond required by the court or adjudicative body before which such Proceeding is taking place) and (y) agree in writing to be fully responsible for all Losses relating to such proceeding; provided, further, that: (a) the Indemnitee shall be entitled to participate in the defense of such claim and to employ counsel of its choice for such purpose at its own expense; and (b) the Indemnifying Party shall not be entitled to assume control of such defense without the prior written consent of the Indemnitee if (i) the claim for indemnification relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (ii) the Indemnitee reasonably believes an adverse determination with respect to the Proceeding giving rise to such claim for indemnification would be materially detrimental to or materially injure the Indemnitee’s reputation or future business prospects, (iii) such claim seeks an injunction or equitable relief against the Indemnitee, (iv) a conflict of interest exists between the Indemnifying Party and the Indemnitee, or (v) the Indemnifying Party failed or is failing to

35

vigorously prosecute or defend such claim.  In any event, the Indemnitee, the Indemnifying Party and the Indemnifying Party’s counsel shall cooperate in the compromise of, or defense against, any such asserted liability; provided, however, that Indemnifying Party shall not compromise or settle any such matter without Indemnitee’s prior written consent. If the Indemnifying Party chooses to defend any claim, the Indemnitee shall make available to the Indemnifying Party any books, records or other documents within its control that are necessary or appropriate to such defense.

8.7           Payment.  The Indemnifying Party shall pay the Indemnitee the amount of established claims for indemnification within ten (10) days after the establishment thereof (the “Due Date”). Any amounts not paid by the Indemnifying Party when due under this Section 8.7 shall bear interest from the Due Date thereof until the date paid at a rate equal to three (3) points above the interest announced from time to time by Citibank, N.A. as its prime or base rate of interest. All payments after the Closing by the Seller to a Buyer Indemnified Party pursuant to this Section 8 shall be satisfied as follows: (i) first, from the Escrow Funds (to the extent funds from the Escrow Funds are sufficient) and Buyer and the Seller shall execute the necessary documents instructing the Escrow Agent to make the applicable payments, and (ii) second, paid by Seller in cash to Buyers; provided, that, if Seller fails to satisfy its cash payment obligations pursuant to this Section 8.7, Buyers may elect (in their sole discretion) to satisfy any such outstanding amounts by forfeiture of Preferred Units and Class A Units (in the same proportion and at the same issuance price implied by the Contribution Agreement).  On the Escrow Release Date, Buyer and Seller shall execute the necessary documents instructing the Escrow Agent to release to Seller an amount equal to the balance of the Escrow Funds minus the aggregate amount, if any, which any Buyer Indemnified Party has claimed under this Section 8 (to the extent such claims, if any, remain unresolved or are resolved but unpaid as of the Escrow Release Date).  To the extent there are any unresolved and/or unpaid claims as of the Escrow Release Date, Buyer and Seller shall execute the necessary documents instructing the Escrow Agent to make the applicable payment to the party entitled to such amounts upon resolution of such claims.  Seller shall take all action requested by Buyers in connection with the reduction and/or forfeiture of the Class A Units and Preferred Units and hereby irrevocably appoints Buyer (or its designee(s)) as its attorney-in-fact with full power to act on its behalf in connection therewith.  Notwithstanding anything to the contrary herein, in the LLC Agreement, the Contribution Agreement, or the Incentive Equity Subscription Agreement, Buyers and their Affiliates shall not have any obligation to make any payments or other distributions under the RTI Units so long as any indemnification claims are in dispute or payment thereof is outstanding.

8.8           Indemnification Rights. The right of any Party to indemnification, reimbursement or other remedy based upon the representations, warranties, covenants and obligations contained herein shall not be affected by any investigation conducted with respect to, or any Knowledge acquired (or capable of being acquired) at any time, whether before or after the Closing Date, with respect to the accuracy or inaccuracy of or compliance with any such representation, warranty, covenant or obligation, including — without limitation — by any report that may have been received by Buyers from Seller or resulting from Buyers’ due diligence procedures conducted with respect to the Group Companies.

36

8.9           No Double-Recovery. Notwithstanding anything to the contrary herein, the Buyer Indemnitees shall not be entitled to recover for any particular Loss to the extent such Buyer Indemnitees have recovered such Loss from another Seller Party.

8.10         Letter Agreement. Notwithstanding anything to the contrary herein, (a) Buyer and its Affiliates shall not be restricted from or in any way limited (including by Section 8.5) in their ability to recover from Seller pursuant to that certain letter agreement between Seller (on behalf of the sellers in the Original Agreement) and RTS, dated as of January 29, 2010 (the “Letter Agreement”) and (b) the Buyer Indemnitees may make claims under the Letter Agreement without recovering from the Escrow Agreement or any other available security; provided, that notwithstanding the foregoing, the Buyer Indemnitees may in their sole discretion) make claims under this Agreement for the matters covered by the Letter Agreement.

9.             Restrictive Covenants.

9.1           Restrictive Covenants.  For a period of five (5) years following the Closing Date, Seller shall not, nor shall he permit any Person (alone or together with others) controlling, controlled by, Affiliated with or related to Seller to, directly or indirectly (including through ownership, management, operation, or control of any other Person, or participation in the ownership, management, operation or control of any other Person, or by being connected with or having any interest in, as a stockholder, agent, consultant or partner, any other Person):

(a)           make statements or representations, or otherwise communicate, directly or indirectly, in writing, orally, or otherwise, to any vendors, payors, referring physicians or any other third parties, or take any action which may, directly or indirectly, disparage any Group Company, their respective Affiliates or any of such Person’s officers, directors, employees, advisors, businesses, or reputations. Notwithstanding the foregoing, nothing in this Agreement shall preclude Seller from making truthful statements or disclosures that are required by applicable law, regulation or legal process;

(b)           engage in the ownership, operation, control, or management of radiation oncology facilities, or otherwise engage in the provision of radiation oncology services (whether as a separate business or in conjunction with any business or practice) (a “Competing Business”) anywhere in Latin America or the Caribbean or any other jurisdiction in the world that the Company or any of its Affiliates is operating or planning to operate (the “Service Area”);

(c)           have any interest, whether as owner, stockholder, member, partner, director, officer, consultant or otherwise, in any Competing Business in the Service Area; provided, however, that the foregoing restriction shall not prevent Seller from owning stock in any Competing Business listed on a national securities exchange or traded in the over-the-counter market provided that Seller does not own more than an aggregate of one percent (1%) of the stock of such entity; or

(d)           directly or indirectly employ or retain or attempt to employ or retain or knowingly arrange or solicit to have any other Person employ or retain, any employee, consultant or any Person who heretofore has been employed or retained by Group Company in

37

connection with any aspect of the Business during the eighteen (18) month period prior to the Closing Date or anytime thereafter.

9.2           Reasonableness of Restrictive Covenants.  Seller acknowledges and agrees that Buyer and its Affiliates operate the Business internationally and therefore, the restrictive covenants contained herein have unique value to Buyers, the breach of which cannot be adequately compensated in an action of law. Seller further agrees that, in the event of the breach of the restrictive covenants contained herein, Buyers shall be entitled to obtain appropriate equitable relief, including, without limitation, a permanent injunction or similar court order enjoining Seller from violating any of such provisions, and that pending the hearing and the decision on the application for permanent equitable relief, Buyers shall be entitled to a temporary restraining order and a preliminary injunction. The prevailing Party shall be entitled to reimbursement from the other Party of its reasonable costs and expenses (including attorneys’ fees and disbursements) of, or related to, such action or proceeding. No such remedy shall be construed to be the exclusive remedy of Buyers and any and all such remedies shall be held and construed to be cumulative and not exclusive of any rights or remedies, whether at law or in equity, otherwise available under the terms of this Agreement, at common law, or under federal, state or local statutes, rules and regulations.  If any court of competent jurisdiction shall deem any of the restrictive covenants contained in this Section 9.2, or portion of any such covenants, too extensive or unenforceable, the other provisions of this Section 9.2 shall nevertheless stand and remain enforceable according to their terms. In such circumstance, the Parties expressly authorize the court to modify such covenants or offending portion thereof, so that the restrictions, limitations and scope of the restrictive covenants extend for the longest period, comprise the largest territory and are enforceable to the maximum permissible extent by law under the circumstances.  The provisions of this Section 9.2 shall survive the execution and delivery of this Agreement.

10.           Disclosure of Information.

10.1         Confidential Information. Each of the Parties hereto recognizes and acknowledges that (a) the Transaction (including the terms and existence of this Agreement and the other Transaction Documents) are highly confidential matters and (b) during the course of negotiations in connection with the transaction contemplated hereby each Party will grant access to, certain plans, systems, methods, designs, procedures, books and records relating to operations, personnel and practices, as well as records, documents and information concerning business activities, practices, procedures and other confidential information of the other Party (all of the foregoing, collectively, the “Confidential Information”), all of which constitute and will constitute valuable, special and unique assets of such Party’s business.  Seller agrees to treat Confidential Information as confidential, shall make all reasonable efforts to preserve its confidentiality, and shall not duplicate or disclose such Confidential Information, except in connection with the transaction contemplated hereby to advisors, attorneys, accountants, bankers, investment bankers, consultants and affiliates (the foregoing parties being referred to herein as “Designated Representatives”) Seller, in its reasonable discretion, shall deem necessary and which Designated Representatives shall agree to be bound by an obligation of confidentiality at least as restrictive as set forth herein. Except for such disclosure to Designated Representatives as may be necessary or appropriate and such public or other disclosures as may be required by court order or any state or federal law or regulation to which a Party is subject or in order to

38

defend litigation (in which case the disclosing Party shall provide the other Party with notice and a copy of the required disclosure a reasonable period of time in advance of such disclosure), the Parties agree to use all reasonable efforts to maintain in confidence the existence and terms of this Agreement and the Transaction and no Party shall issue any press release or public statement without the prior written consent of all other Parties.

10.2         Injunctive Relief. The Parties hereto acknowledge that the restrictions contained in Section 10.1, in view of the nature of the business in which the other Parties are engaged, are reasonable and necessary in order to protect the respective legitimate interests of such other Parties, and that any material violation thereof could result in irreparable injuries to such other Party. Each therefore acknowledges that, in the event of a breach or threatened breach of the provisions of this Section 10, the other Party shall be entitled to obtain from any court of competent jurisdiction, preliminary and permanent injunctive relief restraining the breaching Party from disclosing any such records, documents or information to any person, firm, corporation, association or other entity whatsoever or from using any thereof in any manner whatsoever.

10.3         Other Remedies. Nothing contained in Section 9 or this Section 10 shall be construed as prohibiting any Party hereto from pursuing any other remedies available to it for any such breach or threatened breach, including the recovery of damages.

10.4         Survival. The provisions of this Section 10 shall survive the execution and delivery of this Agreement.

11.           Directors and Officers. Seller agrees to take actions directed by Buyer to reconstitute the boards of directors slate of any of the Group Companies in the manner designated by Buyer. During the period during which Seller is eligible to earn the Earnout Payment or make investments in New Projects and for so long as Seller is an employee of the Group Companies (the “Eligibility Period”), if requested by Seller, Buyer will use commercially reasonable efforts to designate a representative of Seller as a member (or observer) of the board of directors of each Group Company requested by Seller for the Eligibility Period.

12.           Further Assurances.  Each of the Parties hereto shall, at the request of the other Party, furnish, execute and deliver such documents, instruments, certificates, notices and further assurances as counsel for the requesting Party shall reasonably deem necessary or desirable to effect complete consummation of this Agreement and the consummation of each of the Transaction Documents and to carry out the Transactions, or in connection with the preparation and filing of reports required or requested by any Governmental or Regulatory Authority.  At either Party’s request and upon reasonable notice, the other Party shall provide the requesting Party with access to all books and records related to the Business for purposes of review by any Governmental or Regulatory Authority having jurisdiction over Buyers or Seller.

13.           Miscellaneous.

13.4         Waivers and Amendments. This Agreement may be amended, modified, superseded, canceled, renewed or extended, and the terms and conditions hereof may be waived, only by a written instrument signed by the Parties or, in the case of a waiver, by the Party waiving compliance. No delay on the part of any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any Party of any right, power or privilege hereunder, nor any single or partial exercise of any right, power or privilege hereunder, preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder. The rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies which any Party may otherwise have at law or in equity.
