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

The Board of Directors of Syntel, Inc. (“Syntel”) has approved the recommendation by its Compensation Committee and its Nominating and Corporate Governance Committee to change non-employee director compensation by changing the restriction period for restricted stock units granted to directors. Effective June 1, 2015, the restriction period on restricted stock units granted to non-employee directors upon their being elected to the Board of Directors no longer ceases upon the occurrence of the next annual shareholder meeting. Instead, the restriction period for restricted stock units granted to non-employee directors upon their being elected to the Board of Directors ceases for each director on the day upon which he or she ceases to serve on Syntel’s Board of Directors. The form of the restricted stock unit agreement as revised to effectuate this change is attached as Exhibit 10.1.
