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

On July 27, 2016, the stockholders of Juniper Pharmaceuticals, Inc. (the “Company”) approved the Amended and Restated 2015 Long-Term Incentive Plan (the “Amended Plan”) at the 2016 Annual Meeting of Stockholders (the “2016 Annual Meeting”). The Amended Plan had been previously approved by the board of directors (the “Board”) of the Company on May 11, 2016, subject to stockholder approval. The Amended Plan provides for the following changes, among others to the 2015 Long-Term Incentive Plan: (i) an increase in the number of shares of the Company’s common stock reserved for issuance under the Amended Plan by 1,500,000 shares; (ii) removes the limitation on the number of shares of common stock that may be issued pursuant to full value awards, such that each stock option or stock appreciation right granted under the Amended Plan will reduce the share pool by one share, and each stock award, stock unit, performance share or other stock-based award will reduce the share pool by two shares; (iii) each award granted under the Amended Plan (other than a substitute award), will be subject to a minimum restricting and/or vesting period of 12 months from the date of grant; (iv) awards granted on or after the date of the Amended Plan will accelerate only if the participant is terminated without cause within 24 months following a change of control, provided the successor assumes or substitutes the outstanding awards for awards under its own equity plan, and (iv) an increase to the maximum number of shares subject to awards that may be granted to a participant in a calendar year to 400,000.

The material terms of the Amended Plan are described on pages 45 to 54 of the Company’s definitive proxy statement (the “Proxy Statement”) for the 2016 Annual Meeting filed with the Securities and Exchange Commission on June 22, 2016 under the heading “Proposal 3—Approval of Amended and Restated 2015 Long-Term Incentive Plan,” which description is incorporated herein by reference.
