Explanation of Responses:
(1) The reporting person beneficially owned an additional 562 shares of MDR common stock as of the date she became a Section 16 reporting person, which shares were inadvertently omitted from the reporting person's original Form 3 filing. Accordingly, this Form 3 Amendment is being filed to correctly state the number of shares of MDR common stock beneficially owned by the reported person as of the date she became a Section 16 reporting person.
(2) The restricted stock units were granted to the reporting person on February 27, 2019 and vest in three equal annual installments beginning February 27, 2020.
(3) Each restricted stock unit represents a contingent right to receive the value of one share of MDR common stock, with such restricted stock units to be paid, in the sole discretion of the Compensation Committee: (i) in shares of MDR common stock, (ii) cash equal to the fair market value of the shares of MDR common stock otherwise deliverable, or (iii) any combination thereof.
(4) The restricted stock units vest in three equal annual installments beginning February 14, 2019.
(5) Each restricted stock unit represents a right to receive the value of one share of MDR common stock.
