Item 5.02.  Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

As previously announced on a Current Report on Form 8-K filed on April 28, 2016, the Board of Directors (the “Board”) of United Therapeutics Corporation (the “Company”) appointed Michael Benkowitz as President and Chief Operating Officer and re-appointed Martine Rothblatt, Ph.D. as the Company’s Chairman and sole Chief Executive Officer. These changes become effective on June 26, 2016, to coincide with the effective date of the resignations of the Company’s former President and Co-Chief Executive Officer and Executive Vice President and Chief Operating Officer.

In connection with these management changes and subsequent management restructuring, on June 20, 2016 the Compensation Committee (the “Committee”) of the Board approved an amendment and restatement of Mr. Benkowitz’s employment agreement in the form attached as Exhibit 10.1.

Mr. Benkowitz’s new employment agreement replaces his former employment agreement, dated as of February 16, 2011. Mr. Benkowitz’s Employment Agreement has an initial term of three years, and is automatically extended by additional one-year periods at the end of the then-current term unless at least 60 days prior to the end of the then-current term, either party delivers notice not to extend the agreement. The agreement provides for a minimum annual base salary of $650,000, which will be subject to review and annual increase by the Company at its discretion.

The agreement provides that if Mr. Benkowitz’s employment is terminated by the Company other than for cause (as such term is defined), he is entitled to payment of an amount equal to his base salary for the time remaining in the then-current initial or renewal term, payable in semi-monthly installments and as is otherwise consistent with the Company’s payroll procedures. If Mr. Benkowitz’s employment is terminated after a change of control of the Company, he will also be entitled to an acceleration of all unvested stock options, share tracking awards and any other awards subject to vesting. The agreement prohibits Mr. Benkowitz from accepting employment, consultancy or other business relationships with an entity that directly competes with the Company for a period of one year following his last receipt of compensation from the Company.

The foregoing summary is qualified in its entirety by reference to the full text of Mr. Benkowitz’s Employment Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K.
