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

On April 1, 2013, the Board of Directors (the “Board”) of Cognizant Technology Solutions Corporation (the “Company”) adopted, subject to stockholder approval, an amendment and restatement of the 2004 Employee Stock Purchase Plan (as amended and restated, the “ESPP”). On June 4, 2013, the Company held its Annual Meeting of Stockholders (the “Annual Meeting”) at which its stockholders approved the ESPP. The amendment to the ESPP increased the total number of shares of the Company’s Class A Common Stock authorized for issuance under the ESPP by 5,000,000 shares, from 9,000,000 shares to 14,000,000 shares, and did not make any other changes to the ESPP.

The ESPP is administered by the Compensation Committee of the Board of Directors. The ESPP permits eligible employees to purchase shares of the Company’s Class A Common Stock at the end of pre-established offering periods at a purchase price equal to the lesser of (1) 90% of the stock’s fair market value on the first day of the offering period or (2) 90% of the stock’s fair market value on the last day of the offering period. Purchases are funded through employee payroll deductions. The ESPP is intended to comply with Section 423 of the Internal Revenue Code.

The foregoing summary of the ESPP, and the summary of the ESPP set forth in our Definitive Proxy Statement for the Annual Meeting filed with the Securities and Exchange Commission on April 19, 2013, are qualified in their entirety by reference to the full text of the ESPP, which is filed as Exhibit 10.1 to this Current Report and incorporated herein by reference.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On June 4, 2013, the Board adopted Amended and Restated Bylaws of the Company (the “Bylaws”), replacing the former Amended and Restated Bylaws of the Company in their entirety. The Bylaws became effective immediately upon their adoption by the Board.

The Bylaws are substantially the same as the prior bylaws, with the following substantive changes. The Bylaws provide broader indemnification rights to officers, directors and other persons than the prior bylaws and related conditions and procedures with respect thereto, including the advancement of expenses incurred by such persons in connection with certain claims.

The above description of the Bylaws does not purport to be complete and is qualified in its entirety by reference to the full text of the Bylaws, which is filed as Exhibit 3.2 to this Current Report and incorporated herein by reference.
