Section 7.1 “Salary” is deleted in its entirety and replaced with the following:

“Section 7.1 Salary. Commencing on the Employment Commencement Date, the Corporation shall pay the Employee an annual base salary of Five Hundred Thousand dollars ($500,000), which amount shall thereafter be reviewed by the Board or the Compensation Committee at the end of each fiscal year commencing with the fiscal year ending December 31, 2007. The Employee’s salary may also be increased from time to time in the discretion of the Board. The Corporation will pay the Employee his annual salary in accordance with the Corporation’s normal payroll practices.”

Section 7.2 “Annual Bonus” is deleted in its entirety and replaced with the following:

“Section 7.2 Annual Bonus. The Employee shall be eligible to earn an annual bonus as determined by the Compensation Committee or Board. The bonus will be based upon the achievement by the Corporation of certain objectively determinable financial performance targets directly tied to revenue growth and EBITDA performance of the Corporation or such other objectives established by the Board or the Compensation Committee and approved by the Board. For each year of the Term, the Corporation shall adopt an annual bonus program affording the Employee an opportunity to earn bonuses equal to 100% of his annual base salary. Notwithstanding the foregoing, the Executive’s bonus for 2007 (i.e., $250,000 which is pro-rated for six months of service in 2007) shall be based upon the following criteria:

(a) 50% of the 2007 bonus ($125,000) shall be earned and payable in accordance with the terms and conditions of the Corporation’s 2007 Executive Incentive Plan based upon the Corporation earning $30.5 million of EBITDA for 2007; provided, however, certain expenses not budgeted during the 2007 budgeting process such as incremental salary and benefit expenses (i.e., CFO, CIO and VP of Recruiting); the engagement of The Breakaway Group; Delaware franchise taxes related to the 2006 formation of Holdings; the additional expense/accrual related to the change in auditors; and the amount of 2006 discretionary bonuses paid in excess of the 2006 bonus accrual shall be excluded from the calculation of EBITDA for 2007; and

(b) 50% of the 2007 bonus ($125,000) shall be based upon Executive’s successful completion of the following by December 31, 2007:

(i) hiring of a new Chief Financial Officer ($41,667);

(ii) identifying and securing the commitment of a qualified radiation oncologist to become the Corporation’s Medical Director ($41,667); and

(iii) delivery to the Board of a written strategic plan for the Corporation ($41,667).”

Section 7.4 “Options” is amended by deleting the first sentence thereof and replacing it with the following:

“On or as soon as reasonably practicable following the Employment Commencement Date, and subject to approval by the Compensation Committee or Board, the Employee will receive an option to purchase 773,574 shares of Common Stock, at an exercise price of $3.50 per share, pursuant to the terms of Holdings’ Equity Incentive Plan (the “Stock Options”).”
