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

On February 24, 2016, David Orfao notified the Board of Directors (the “Board”) of Imprivata, Inc. (the “Company”) of his intent to resign from the Board, and from each of the Audit Committee of the Board (the “Audit Committee”) and the Compensation Committee of the Board (the “Compensation Committee”), effective immediately. The decision of Mr. Orfao to resign was not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

On February 24, 2016, the Board appointed Ms. Kate Walsh to serve as a member of the Board to fill the vacancy created by Mr. Orfao’s resignation. Ms. Walsh will serve as a Class I director with her term expiring at the Company’s 2018 annual meeting of stockholders, or until her earlier resignation, removal or death. Ms. Walsh will also serve on the Company’s Audit Committee and Compensation Committee.

In connection with her election to the Board, Ms. Walsh was granted options to acquire 70,000 shares of the Company’s common stock at an option price of $11.05 per share, the closing price of the Company’s common stock on the date of grant. The options will vest quarterly over a four year period, subject to Ms. Wash’s continued service as a director of the Company.

There are no arrangements or understandings between Ms. Walsh and any other person pursuant to which she was selected as a director, nor are there any transactions in which Ms. Walsh has an interest that would be reportable under item 404(a) of Regulation S-K. Ms. Walsh will receive the standard compensation arrangements for the Company’s non-employee directors, including annual fees and equity-based compensation.
