If Executive files any charge or complaint with any Government Agency and if the Government Agency pursues any Claim on Executive’s behalf, or if any other third party pursues any claim on Executive’s behalf, Executive waives any right to monetary or other individualized relief (either individually, or as a part of

any collective or class action), provided that nothing in this Release limits any right Executive may have to receive a whistleblower award or bounty for information provided to the Securities and Exchange Commission.

5.No Assignment. Executive represents and warrants to the Company Releasees that there has been no assignment or other transfer of any interest in any Claim that Executive may have against the Company Releasees. Executive agrees to indemnify and hold harmless the Company Releasees from any liability, claims, demands, damages, costs, expenses and attorney’s fees incurred as a result of any such assignment or transfer from Executive.

6.Severability. In the event any provision of this Release is found to be unenforceable by an arbitrator or court of competent jurisdiction, such provision shall be deemed modified to the extent necessary to allow enforceability of the provision as so limited, it being intended that the Parties shall receive the benefit contemplated herein to the fullest extent permitted by law. If a deemed modification is not satisfactory in the judgment of such arbitrator or court, the unenforceable provision shall be deemed deleted, and the validity and enforceability of the remaining provisions shall not be affected thereby.

7.Interpretation; Construction. The headings set forth in this Release are for convenience only and shall not be used in interpreting this Release. This Release has been drafted by legal counsel representing the Company, but Executive has participated in the negotiation of its terms. Furthermore, Executive acknowledges that Executive has had an opportunity to review and revise the Release and have it reviewed by legal counsel, if desired, and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting Party shall not be employed in the interpretation of this Release. Either Party's failure to enforce any provision of this Release shall not in any way be construed as a waiver of any such provision, or prevent that party thereafter from enforcing each and every other provision of this Release.

8.Governing Law and Venue. This Release will be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts applicable to contracts made and to be performed wholly within such Commonwealth, and without regard to the conflicts of law principles that would result in the applicable of the laws of another jurisdiction. Any suit brought hereon shall be brought in the state or federal courts sitting in Boston, Massachusetts, the parties hereby waiving any claim or defense that such forum is not convenient or proper. Each Party hereby agrees that any such court shall have in personam jurisdiction over it and consents to service of process in any manner authorized by Massachusetts law.

9.Entire Agreement. This Release, the Severance Agreement, the Confidentiality and Non-Compete Agreement, the Radius Health, Inc. 2018 Stock Option and Incentive Plan, any predecessor plan, the applicable stock option or other equity award agreements between the Executive and the Company (subject to the Accelerated Vesting set forth above) constitute the entire agreement of the Parties in respect of the subject matter contained herein and therein and supersede all prior or simultaneous representations, discussions, negotiations and agreements, whether written or oral. This Release may be amended or modified any with the written consent of Executive and an authorized representative of the Company. No oral waiver, amendment or modification will be effective under any circumstances whatsoever.

10. Counterparts. This Release may be executed in multiple counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument.
