Item 502(e).     On July 8, 2011, the Compensation Committee of Radius Health, Inc. (the “Company”) recommended, and on July 14, 2011 the Board of Directors approved, the base compensation for 2011 to be paid by the Company to the Company’s named executive officers as defined by item 402(a) of Regulation S-K: (i) Gary Hattersley, Ph.D, Vice President Biology (“Hattersley”); (ii) Louis O’Dea, MB, Senior Vice President, Chief Medical Officer; (“O’Dea”) (iii) C. Richard Lyttle, Ph.D, Director, President and Chief Executive Offer (“Lyttle”); and (iv) Nick Harvey, Senior Vice President, Chief Financial Officer, Treasurer and Secretary (“Harvey” and together with Hettersley, O’Dea and Lyttle, the “Named Executive Officers”). The approved changes provide that Hattersley will receive a base salary of $230,576 per year beginning January 1, 2011, O’Dea will receive a base salary of $328,944 per year beginning January 1, 2011, Lyttle will receive a base salary of $389,980 per year beginning January 1, 2011, and Harvey will receive a base salary of $288,936 per year beginning January 1, 2011.

Item 502(f).     On July 8, 2011, the Compensation Committee of the Company, based on the established goals for 2010 executive bonuses (the “2010 Bonus Plan”), recommended, and on July 14, 2011 the Board of Directors approved, the award of cash bonuses for the Company’s Named Executive Officers as set forth on the table below.  Under the 2010 Bonus Plan each executive officer is eligible to receive an annual performance-based cash bonus, in an amount up to a fixed percentage of his base salary. At the beginning of each year the board develops with input from our President and Chief Executive Officer a list of corporate goals for the year that would be used as a guideline to assess the annual performance of the executive officers. As soon as practical after the year is completed, the board reviews actual performance against the stated goals and determines subjectively what it believes to be the appropriate level of cash bonus. Whether or not a cash bonus is paid is entirely at the discretion of the board of directors.

The total 2010 compensation for each Named Executive Officer reported in the Summary Compensation Table on page 51 of the Company’s Form S-1 filed with the Securities and Exchange Commission on June 23, 2011, has been recalculated to include the 2010 bonuses as follows:
