WHEREAS, the Executive is currently employed by the Company as its Medical Director and Secretary and is a licensed radiation oncologist who provides medical services at the Company’s radiation therapy centers;

WHEREAS, the Company has entered into that certain Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Radiation Therapy Investments, LLC, a Delaware limited liability company, Holdings and RTS MergerCo, Inc., a Florida corporation (“Merger Sub”), dated as of October 19, 2007, pursuant to which Merger Sub will merge with and into the Company (the “Merger”), with the Company as the surviving corporation in the Merger and a wholly-owned subsidiary of Holdings;

WHEREAS, the Executive and the Company are currently parties to an Executive Employment Agreement dated as of April, 2004 (the “Prior Executive Agreement”), and the Executive is currently party to a Physician Employment Agreement, dated as of April, 2004, with 21st Century Oncology, Inc.

WHEREAS, the Company wishes to assure itself of the continued services of the Executive for the period provided in this Agreement and the Executive is willing to serve in the employ of the Company for such period upon the terms and conditions hereinafter set forth; and

NOW THEREFORE, in consideration of the mutual covenants herein contained, the parties, intending to be legally bound, hereby agree as follows:

1. EMPLOYMENT. The Company hereby agrees to employ the Executive upon the terms and conditions herein contained, and the Executive hereby agrees to accept such employment for the term described below. The Executive agrees to serve as the Company’s Medical Director and Secretary during the term of this Agreement. In such capacity, the Executive shall have the authorities, functions, powers, duties and responsibilities that are customarily associated with such positions and as the Chief Executive Officer may reasonably assign to him from time to time consistent with such positions.

Throughout the term of this Agreement, the Executive shall devote his best efforts and substantially all of his business time and services to the business and affairs of the Company. The Executive currently serves on the board of directors of the entities set forth on the attached

Exhibit A. Nothing herein shall preclude Executive from (i) providing physician services for up to two (2) days per week pursuant to the Physician Agreement, (ii) serving or continuing to serve on the board of directors of entities that do not compete with the Company and to the extent such service does not materially interfere with Executive’s performance under this Agreement or the Physician Agreement; provided that Executive will not agree to serve or actually serve on the board of directors of any entity for which he has not previously served without first notifying the Board or (iii) serving or continuing to serve on the boards or advisory committees of medical, charitable or other similar organizations to the extent such service does not materially interfere with Executive’s performance under this Agreement or the Physician Agreement. As periodically requested by the Board, Executive shall use commercially reasonable efforts to assist the Board in determining whether Executive’s membership on the board of directors or any other involvement with any entity could reasonably be expected to result in health care compliance issues or liability for the Company or any of its subsidiaries, affiliates and/or joint ventures and to take such actions as are reasonably requested by the Board to remedy and/or mitigate any such issues or liability identified by the Board.

2. TERM OF AGREEMENT. The initial three (3) year term of employment under this Agreement shall commence as of the date of closing of the Merger (the “Effective Date”). After the expiration of such initial 3 year employment period, the term of the Executive’s employment hereunder shall automatically be extended without further action by the parties for successive two (2) year renewal terms, provided that if either party gives the other party at least one hundred twenty (120) days advance written notice of its intention to not renew this Agreement for an additional term, the Agreement shall terminate upon the expiration of the current term.

Notwithstanding the foregoing, the Company shall be entitled to terminate this Agreement immediately before the end of the initial term or any renewal term, subject to a continuing obligation to make the payments, if any, required under Section 6 below, if the Executive (i) becomes Disabled (as defined in Section 6(c) below), (ii) is terminated by the Company for Cause or without Cause or (iii) voluntarily terminates his employment for Good Reason or for any other reason or no reason before the then current term of this Agreement expires.

3. EXECUTIVE COMPENSATION.

(a) Annual Base Salary. Subject to Section 5 below, the Executive shall receive an annual base salary during the term of this Agreement at a rate of not less than Four Hundred Thousand Dollars ($400,000) (as adjusted from time to time pursuant to this Agreement, the “Base Salary”), payable in installments consistent with the Company’s normal payroll schedule. The Board or its Compensation Committee (the “Compensation Committee”) shall review this Base Salary at annual intervals, and may, but shall not be obligated to, adjust the Base Salary from time to time as the Board or the Compensation Committee deems to be appropriate.

(b) Performance Incentive Bonus. The Executive shall also be entitled to receive an annual performance-based incentive bonus from the Company during the term of this Agreement with a target bonus amount not less than $400,000 per annum (as the

Board may, but shall not be obligated to adjust from time to time, the “Target Bonus”), the actual amount of the bonus to be determined by the Board, in good faith, on an annual basis pursuant to a bonus plan based on factors including, without limitation, the Company’s achievement of earnings before interest, taxes, depreciation and amortization and net debt targets (the “Bonus Plan”); ; provided, that Executive’s 2008 Bonus shall be determined as set forth on Exhibit B. The bonus amount to be paid to the Executive in any given year pursuant to the Bonus Plan shall be referred to as the Executive’s “Bonus.” The Bonus shall be paid to the Executive within thirty (30) days following the availability of the Company’s annual financial statements and shall be payable in cash.

4. ADDITIONAL COMPENSATION AND BENEFITS. The Executive shall receive the following additional compensation and welfare and fringe benefits:

(a) Participation in Benefit Plans. The Executive shall be eligible to participate in the employee benefit plans and programs maintained by the Company from time to time for its executives, or for its employees generally, including without limitation any life, medical, dental, accidental and disability insurance and profit sharing, pension, retirement, savings, stock option, incentive stock and deferred compensation plans, in accordance with the terms and conditions as in effect from time to time.

(b) Vacation. The Executive shall be entitled to no less than five weeks of vacation (or such greater vacation benefits as may be provided in the future by the Board or Compensation Committee) during each year during the term of this Agreement and any extensions thereof, prorated for partial years.

(c) Business Expenses. The Company shall reimburse the Executive for all reasonable expenses he incurs in promoting the Company’s business, including expenses for travel, entertainment of business associates, service and usage charges for business use of cellular phones and similar items, upon presentation by the Executive from time to time of an itemized account of such expenditures.

(d) Other. In addition to the benefits provided pursuant Sections 4(a), 4(b) and 4(c), the Executive shall be eligible to participate in such other executive compensation and retirement plans of the Company as are available generally to other officers, and in such welfare benefit plans, programs, practices and policies of the Company as are generally applicable to other key employees, including any deferred compensation plan made generally available to the senior officers of the Company. The Company will use commercially reasonable efforts to obtain on behalf of Executive long-term disability insurance coverage during the term of the Agreement on such terms and conditions as are standard in the industry.

5. PHYSICIAN AGREEMENT. The compensation set forth in Section 3 above is intended to compensate Executive for the services he provides while Medical Director and Secretary. If the Physician Agreement is terminated for any reason, but this Agreement is not terminated, the Agreement shall remain in full force and effect except that Executive’s annual base salary shall be increased to $700,000 and subsection (i) of Section 1 of this Agreement shall be deemed to be of no further force or effect.

6. PAYMENTS UPON TERMINATION.

(a) Involuntary Termination. If the Executive’s employment is terminated by the Company during the term of this Agreement, the Executive shall be entitled to receive his Base Salary accrued and unpaid through the date of termination (the “Termination Date”) and his earned and unpaid Bonus, if any, for the fiscal year ending prior to the Termination Date. The Executive shall also receive any nonforfeitable benefits already earned and payable to him under the terms of any deferred compensation, incentive or other benefit plan maintained by the Company, payable in accordance with the terms of the applicable plan. The payments and benefits that the Executive shall be entitled to pursuant to this Section 6(a) are collectively referred to as the Executive’s “Accrued Compensation”.

(b) Severance Payments. If the Executive’s employment is terminated (i) by the Company without Cause or (ii) by the Executive for Good Reason, in addition to payment of the Accrued Compensation, the Company shall also be obligated to make a series of monthly payments to the Executive for a period of twenty four (24) months immediately following the Termination Date. Each monthly payment shall be equal to one-twelfth (1/12th) of the sum of (x) the Executive’s annual Base Salary, as in effect on the Termination Date, plus (y) the Executive’s Bonus for the year immediately prior to the year during which termination occurs; provided that for purposes of this Section 6(b), Executive’s 2006 and 2007 Bonus shall each be deemed to be $200,000. Executive shall also be permitted, to the extent permitted under applicable law, to continue to participate at the Company’s expense in all benefit and insurance plans, coverage and programs in which he was participating immediately prior to the Termination Date, for a period of one (1) year from the Termination Date (Executive will reasonably cooperate with the Company to facilitate the continuation of such benefits, including, without limitation, electing “COBRA” coverage as required by the Company). Executive shall not be required to mitigate the amount of any payment or benefit contemplated by this paragraph.

(c) Disability. The Company shall be entitled to terminate this Agreement, if the Board determines that the Executive has been unable to attend to his duties for at least one-hundred and twenty (120) days because of a medically diagnosable physical or mental condition, and has received a written opinion from a physician acceptable to the Board that such condition prevents the Executive from resuming full performance of his duties at such time and during the succeeding 120 days or is likely to continue for an indefinite period (any such condition, a “Disability”). If the Company terminates this Agreement due to Executive’s Disability, the Executive shall be entitled to receive the Accrued Compensation and any disability benefits payable pursuant to any long-term disability plan or other disability program or insurance policies maintained or provided by the Company.

(d) Termination for Cause. If the Executive’s employment is terminated by the Company for Cause, the amount the Executive shall be entitled to receive from the Company shall be limited to the Accrued Compensation.

For purposes of this Agreement, the term “Cause” shall be limited to (i) any action by the Executive involving willful disloyalty to the Company, such as embezzlement, fraud, misappropriation of corporate assets or a breach of the covenants set forth in Sections 9 and 10 below; (ii) the Executive being convicted of or entering a plea of guilty or no contest or similar plea with respect to, a felony; (iii) the Executive being convicted of or entering a plea of guilty or no contest or similar plea with respect to, any lesser crime or offense (x) committed in connection with the performance of his duties hereunder, (y) involving fraud, dishonesty or moral turpitude or (z) that causes the Company or any of its subsidiaries a substantial and material financial detriment; (iv) substantial neglect or willful misconduct in carrying out Executive’s material duties (other than resulting from the Executive’s Disability) or violations of policies of the Company and/or its subsidiaries resulting in material harm to the Company or any of its subsidiaries; (v) substantial and repeated failure, refusal or inability (except where due to illness or Disability) to perform Executive’s duties hereunder or (vi) termination of the Physician Agreement for Cause. Notwithstanding the foregoing, no termination pursuant to subsection (iv) or (v) shall be treated as termination for Cause unless the Board has provided the Executive with written notice specifying in reasonable detail the alleged Cause for termination and the Cause is not cured within 30 days after the date of such notice.

(e) Voluntary Termination by the Executive. If the Executive resigns or otherwise voluntarily terminates his employment and the termination is not for Good Reason, the Executive shall only be entitled to the Accrued Compensation upon such termination.

For purposes of this Agreement, a termination by the Executive shall be for “Good Reason” if the Executive resigns during the period of three months after the date the Executive is (i) assigned to a position other than Medical Director and Secretary of the Company (other than any such assignment for Cause or by reason of Disability) without the Executive’s consent, (ii) assigned duties materially inconsistent with such position (other than any such assignment for Cause or by reason of Disability) without the Executive’s consent, and such assignment is not rectified within 15 business days after written notice to the Company, (iii) transferred to a geographic location of employment more than 30 miles from the current location of employment without the Executive’s consent, (iv) directed to report to anyone other than the Chief Executive Officer, without the Executive’s consent or (v) the Company materially breaches any material term of this Agreement; provided that no breach of this Agreement by the Company shall be deemed to constitute “Good Reason” unless the Executive provides the Board with written notice specifying in reasonable detail the alleged breach and such breach is not cured within 30 days after the date of such notice.

(f) Release. In order to receive the payment(s) provided for in this Section 6, Executive must execute and deliver to the Company a release substantially similar to the form attached hereto as Appendix C.

(g) In the event that any payment or benefits received or to be received by Executive pursuant to this Agreement (“Benefits “) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as

amended (the “Code”), or any comparable successor provisions, and (ii) but for this subsection, would be subject to the excise tax imposed by Section 4999 of the Code, or any comparable successor provisions (the “Excise Tax”), then benefits to which Executive will be entitled pursuant to this Section 6 (the “Benefits “) shall be either: (i) provided to Executive in full, or (ii) provided to Executive as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, when taking into account applicable federal, state, local and foreign income and employment taxes, the Excise Tax, and any other applicable taxes, results in the receipt by Executive, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under the Excise Tax. Unless the Company and Executive otherwise agree in writing, any determination required under this subsection shall be made in writing in good faith by an accountant selected by the mutual agreement of Executive and the Company (the “Accountant”). The Company shall bear all costs the Accountant may reasonably incur in connection with any calculations contemplated by this subsection.

(h) For purposes of this Section 6, the term “Base Salary” as used in this Section 6 shall include the amount of Base Salary (as defined in the Physician Agreement) in effect immediately prior to such termination under the Physician Agreement.

7. DEATH. If the Executive dies during the term of this Agreement, the Company shall pay to the Executive’s estate a lump sum payment equal to the sum of (i) the Executive’s Accrued Compensation, plus (ii) the product of (x) the Board’s good faith estimated annual Bonus for the fiscal year during which the death occurs based on the performance of the Company at the time of death and (y) a fraction, the numerator of which is the number of whole and partial months in the fiscal year in which the death occurs through the date of death, and the denominator of which is 12. In addition, the death benefits payable by reason of the Executive’s death under any retirement, deferred compensation or other employee benefit plan maintained by the Company shall be paid to the beneficiary designated by the Executive in accordance with the terms of the applicable plan or plans.

8. WITHHOLDING. The Company shall, to the extent permitted by law, have the right to withhold and deduct from any payment hereunder any federal, state or local taxes of any kind required by law to be withheld with respect to any such payment.

9. PROTECTION OF CONFIDENTIAL INFORMATION. The Executive agrees that he will keep all confidential and proprietary information of the Company or relating to its business (including, but not limited to, information regarding the Company’s customers, pricing policies, methods of operation, proprietary computer programs and trade secrets) confidential, and that he will not (except with the Company’s prior written consent), while in the employ of the Company or at any time thereafter, disclose any such confidential information to any person, firm, corporation, association or other entity, other than in furtherance of his duties hereunder, and then only to those with a “need to know.” The Executive shall not make use of any such confidential information for his own purposes or for the benefit of any person, firm, corporation, association or other entity (except the Company) under any circumstances during or at any time after the term of his employment. The foregoing shall not apply to any information

which is already in the public domain, or is generally disclosed by the Company or is otherwise in the public domain at the time of disclosure, except if such information is in the public domain as a result of the Executive’s actions in contravention of this Section 9.

The Executive recognizes that because his work for the Company will bring him into contact with confidential and proprietary information of the Company, the restrictions of this Section 9 are required for the reasonable protection of the Company and its investments and for the Company’s reliance on and confidence in the Executive.

10. PROHIBITION OF CERTAIN ACTIVITIES. In consideration of the transactions contemplated hereby and the payment of the Merger Consideration (as defined in the Merger Agreement), the Executive hereby covenants and agrees that he will not, for a period beginning on the date of this Agreement and ending on the later of (a) the fifth anniversary of this Agreement and (b) three (3) years after such Executive’s Termination Date, (i) engage in any business activities for himself or on behalf of any enterprise in any capacity or own any interest in any entity which compete or are competitive with the Company in the business of organizing, establishing, developing, providing or managing radiation therapy services or services ancillary thereto, in any state in which the Company, its subsidiaries, affiliates and/or any of its joint ventures then operate or has plans to operate as of the Executive’s Termination Date, (ii) interfere or disrupt or attempt to interfere or disrupt, the relationships between the Company, its subsidiaries, affiliates and/or joint ventures and any patient, referral source or supplier or other person having business relationships with the Company, its subsidiaries, affiliates and/or joint ventures, (iii) solicit, induce or hire, or attempt to solicit, induce or hire, any employee of the Company, its subsidiaries, affiliates and/or joint ventures or (iv) publish or make any disparaging statements about the Company, any affiliate of the Company, or any of their directors, officers or employees, under circumstances where it is reasonably foreseeable that the statements will be made public (the activities described in clauses (i) through (iv) above, collectively, “Prohibited Activities”). Notwithstanding the foregoing, this Section 10 will be of no force and effect for the period (the “Toll Period”) during which the Company fails to make the payments, if any, required under Section 6(b) and such payments are in fact due and payable pursuant to Section 6(b), provided that the Toll Period shall not take effect unless the Executive provides the Board with written notice that such payments are due and payable and the Company does not make such payments within 30 days after the date of such notice; provided, however that the following shall not be deemed Prohibited Activities under clause (i) above: (x) owning an ownership interest or participation on the board of directors during the term of this Agreement or thereafter in (i) pharmacies, (ii) banks or (iii) health care related insurance companies, PPOs and HMOs; provided that (A) Executive’s participation with any entity listed in clause (x) does not materially interfere with Executive’s performance under this Agreement or the Physician Agreement and (B) no entity listed in clause (x) owns or operates and is not under common control with any entity that owns or operates radiation therapy services or (y) engaging in the practice of medicine, individually or as part of a group practice of five (5) or less radiation oncologists following the termination or expiration of this Agreement; provided, that neither the Executive’s individual nor group practice (i) has affiliated relationships with any other physician practices or (ii) has more than one geographic location. The Executive will be deemed to be engaged in Prohibited Activities if he engages or participates in any entity that engages in Prohibited Activities or becomes affiliated with any person who engages in Prohibited Activities as an employee, officer, director, consultant, agent, partner, proprietor or other participant; provided,

that the ownership of no more than 2 percent of the stock of a publicly traded corporation shall not be deemed participation in or affiliation with an entity or person so long as the Executive has no other connection or relationship with such entity or person.

11. INJUNCTIVE RELIEF. The Executive acknowledges and agrees that it would be difficult to fully compensate the Company for damages resulting from the breach or threatened breach of the covenants set forth in Sections 9 and 10 of this Agreement and accordingly agrees that the Company shall be entitled to temporary and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions, to enforce such provisions in any action or proceeding instituted in the United States District Court for the Western District of Florida or in any court in the State of Florida having subject matter jurisdiction. This provision with respect to injunctive relief shall not, however, diminish the Company’s right to claim and recover damages.

It is expressly understood and agreed that although the parties consider the restrictions contained in this Agreement to be reasonable, if a court determines that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction on the activities of the Executive, no such provision of this Agreement shall be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such extent as such court may judicially determine or indicate to be reasonable.

The Executive acknowledges and confirms that (a) the restrictive covenants contained in Sections 9 and 10 hereof are reasonably necessary to protect the legitimate business interests of the Company, and Holdings’ interests as the purchaser of the Company for substantial consideration, a significant portion of which was paid to Executive and (b) the restrictions contained in Sections 9 and 10 hereof (including without limitation the length of the term of the provisions of Sections 9 and 10 hereof) are not overbroad, overlong, or unfair and are not the result of overreaching, duress or coercion of any kind. The Executive further acknowledges and confirms that his full and faithful observance of each of the covenants contained in Sections 9 and 10 hereof will not cause him any undue hardship, financial or otherwise, and that enforcement of each of the covenants contained herein will not impair his ability to obtain employment commensurate with his abilities and on terms fully acceptable to him or otherwise to obtain income required for the comfortable support of him and his family and the satisfaction of the needs of his creditors. The Executive acknowledges and confirms that his special knowledge of the business of the Company is such as would cause the Company serious injury or loss if he were to use such ability and knowledge to the benefit of a competitor or were to compete with the Company in violation of the terms of Sections 9 and 10 hereof. The Executive further acknowledges that the restrictions contained in Sections 9 and 10 hereof are intended to be, and shall be, for the benefit of and shall be enforceable by, the Company’s successors and assigns.

If the Executive shall be in violation of any provision of Sections 9 and 10, then each time limitation set forth in the applicable section shall be extended for a period of time equal to the period of time during which such violation or violations occur. If the Company seeks injunctive relief from such violation in any court, then the covenants set forth in Sections 9 and 10 shall be extended for a period of time equal to the pendency of such proceeding including all appeals by the Executive.

Sections 8 through 18 of this Agreement shall survive the termination or expiration of this Agreement.

12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given when personally delivered, sent by telecopy or facsimile (with confirmation of receipt), one day after deposit with a reputable overnight delivery service (charges prepaid) and three days after deposit in the U.S. Mail (postage prepaid and return receipt requested) to the address set forth below or such other address as the recipient party has previously delivered notice to the sending party.

2008 Bonus

Executive’s 2008 Bonus shall be determined as follows: (i) 60% of such bonus shall be based on achievement of the Targeted EBITDA for 2008 (as such term is used in the Management Stock Contribution and Unit Subscription Agreement (the “Subscription Agreement”) between such Executive and Radiation Therapy Investments, LLC, a Delaware limited liability company), 30% of such bonus shall be based on achievement of the Targeted Net Debt for 2008 (as such term is used in the Subscription Agreement) and (iii) 10% of such bonus shall be based on achievement of discretionary targets which will be developed in consultation with the Chief Executive Officer. If the Company’s 2008 actual EBITDA is (a) greater than or equal to 85% and less than 90% of Targeted EBITDA, then Executive’s bonus pursuant to clause (i) shall be $48,000, or (b) greater than or equal to 90% and less than 95% of Targeted EBITDA, then Executive’s bonus pursuant to clause (i) shall be $120,000 or (c) greater than or equal to 95% and less than or equal to 100%, then an amount between $120,000 and $240,000, determined based on straight line interpolation between such amounts based on the percentage achieved. If EBITDA for such year exceeds 100% of Targeted EBITDA, then for purposes of clause (i) it shall be deemed to be 100%. The Executive will earn $120,000 if the Company’s actual net debt amount at the end of the 2008 fiscal year is 100% or a lesser percentage of the Targeted Net Debt for such year, however if the Company’s actual net debt is greater than 100% of the Targeted Net Debt for such year, the Executive will instead earn an amount between $0 and $120,000 if the Company’s actual net debt amount at the end of the 2008 fiscal year is greater than 100% of the Targeted Net Debt, but less than 102% of the Targeted Net Debt, based on straight line interpolation between such amounts based on the percentage achieved. The Executive will receive an additional $40,000 if the Executive achieves the discretionary targets developed in consultation with the Chief Executive Officer. In addition, the Executive will earn a bonus in excess of his Target Bonus in an amount between $0 and $120,000 if the Company’s actual EBITDA for 2008 is greater than 100% of the Targeted EBITDA, based on the amount that the Company’s actual EBITDA for 2008 is greater than 100% of the Targeted EBITDA but less than 125% of Targeted EBITDA. This amount will be determined based on a straight line interpolation between such amounts based on the percentage achieved. For the avoidance of doubt, the Executive is eligible to earn a maximum bonus of $520,000 for 2008.
