Dear Lorie:

On behalf of Radius Health, Inc. (the "Company"), with offices at 950 Winter
Street, Waltham, MA, 02451, I am pleased to offer you full-time employment as
the Chief Medical Officer on the terms set forth below. This letter agreement is
subject to, and will become effective only upon, your commencing employment with
the Company on or about July 27, 2015.

In the course of your employment with the Company, you will be subject to and
required to comply with all Company policies, and applicable laws and
regulations. The term "Agreement" as used below shall mean this letter
agreement.

Duties; Work Location

As Chief Medical Officer, you will report to the Company's Chief Executive
Officer and will have such duties and authority as are normally associated with
such position or as may from time to time be assigned to you by the Board of
Directors of Company or an authorized committee (the "Board"). The Company
requires that, as a full-time employee, you devote your full business time,
attention, skill, and efforts to the tasks and duties of your position with the
Company. As a Pennsylvania office based employee, you may work from our offices
in Pennsylvania, Waltham, MA, or Parsippany, NJ as dictated by the needs of the
business. If you elect to relocate to Waltham, MA or Parsippany, NJ Radius will
make relocation assistance available to you. Your duties may require reasonable
business travel as determined by the Chief Executive Officer.

Cash Compensation

You will earn a salary at the semi-monthly rate of $14,583.33 annualized at a
rate of $350,000, or such greater amount as is subsequently determined by the
Board (the "Annual Base Salary"). All compensation amounts payable pursuant to
this Agreement shall be subject to all applicable tax and other withholdings.

In addition, subject to approval of the Board, you will be eligible for an
annual discretionary bonus (your "Annual Bonus"), which Annual Bonus shall be
targeted at 35% (your "Target") of your annualized base salary, subject to
pro-ration during any year in which you are employed for less than the full
year. The Board also has the discretion to award a bonus in excess of your
Annual Target Bonus for exemplary performance. Any Annual Bonus will be based on
both individual and corporate performance and the amount of any such Annual
Bonus will be determined by the Company. Annual Bonuses shall be paid to you
when generally paid to other senior executives of the Company, subject to your
continued employment through the payment date.

You will also be entitled to reimbursement of all business expenses reasonably
incurred in connection with the performance of your functions and duties under
this Agreement, subject to the
Company's expense reimbursement policy in effect from time to time.

Equity Incentive

Subject to approval by the Board after the commencement of your employment, the
Company will grant to you an initial stock option (the "Initial Option") under
the Radius Health, Inc. 2011 Equity Incentive Plan (the "Plan") for the purchase
of 150,000 shares (subject to appropriate adjustment in the event of any stock
split, stock dividend or other similar event) of common stock of the Company
("Common Stock") at a price per share equal to the Common Stock's closing price
on the NASDAQ Global Market on the date of grant. The Initial Option shall be
subject to all terms and other provisions set forth in the Plan

--------------------------------------------------------------------------------

and in a separate option agreement and will vest as to 25% of the underlying
shares on the first anniversary of the date you commence employment with the
Company and in quarterly installments over the following three years.

Sign-On Bonus

You will be eligible to receive a Sign-On Bonus in the gross amount of $50,000
(the "Sign-On Bonus"). This bonus will be paid in two equal installments of
$25,000 each. The first installment will be paid on the first ordinary payroll
date that occurs more than 90 days after the date you commence employment with
the Company, subject to your continued employment with the Company through the
date of payment. The second and final installment will be paid in the first
ordinary payroll date that occurs more than six (6) months after the date you
commence employment with the Company, subject to your continued employment with
the Company through the payment date.

In the unlikely event your employment is terminated for "cause" or if you
voluntarily resign for any reason other than "good reason" (as those terms will
be defined in the executive severance agreement described below) during your
first year of employment, you will be required to repay the full amount of the
Sign-On Bonus amount that has been paid to you as of your termination date
unless a Change of Control (as defined in the Plan) occurs on or prior to such
date.

Benefits

You will be eligible to participate in all of the employee benefits and benefit
plans that the Company generally makes available to its similarly situated
full-time regular employees, including group health plans, life, disability and
AD&D insurances, a 401 (k) plan with Company match, tuition reimbursement, and
various types of paid time off, subject to the terms and conditions of such
benefits and plans. You will be eligible to accrue up to 20 days of vacation (in
addition to Company holidays), which will accrue over the first year· of your
employment and may be used with the advance approval of the Chief Executive
Officer. The Company reserves the right to terminate, modify or add to its
benefits and benefit plans at any time.

Term and Termination

This Agreement shall commence on your first day of your employment with the
Company and may be terminated at any time by you or by the Company with or
without cause. You and the Company acknowledge and agree that your employment is
and shall continue to be at-will and that nothing in this Agreement shalt confer
upon you any right with respect to continuation of employment by the Company,
nor shall it interfere in any way with your right or the Company's right to
terminate your employment at any time.

The Company is in the process of standardizing its executive termination pay
arrangements. On or prior to your commencing employment, you and the Company
will enter into an executive severance agreement (the "Severance Agreement")
(attached) that governs the payments and benefits you may receive upon a
termination of your employment with the Company. Except as otherwise provided in
the Severance Agreement, the Company's obligations to you under this Agreement
will cease upon your termination of employment for any reason. The Severance
Agreement will include substantially the same terms as are offered to other
similarly situated Company executives.
