        <footnote id="F1">Represents the total number of performance-based restricted stock units which vested based upon attainment by the Company of certain performance milestones, as determined by the Company's compensation committee on February 27, 2013 based upon the audited financials for the 2012 fiscal year.  The performance-based restricted stock units were granted on November 28, 2011 under the Cognizant Technology Solutions 2009 Incentive Compensation Plan.  In accordance with the performance-based restricted stock unit award, 1/3 of the vested performance-based restricted stock units shall be issued on the eighteen-month anniversary of the date of grant of such performance-based restricted stock units, provided the reporting person remains in the Company's service through such anniversary date.   (Continued in the next footnote.)</footnote>
        <footnote id="F2">(Continued from the previous footnote.)  The remaining 2/3 of the vested performance-based restricted stock units shall be issued on the thirty-six month anniversary of the date of grant of such performance-based restricted stock units, provided that the grantee remains in the Company's service through such anniversary date. Each performance-based restricted stock unit represents a contingent right to receive one share of the Company's Class A Common Stock.  The reporting person will disclose the receipt of shares of the Company's Class A Common Stock underlying the performance-based restricted stock units on Table I of Form 4, if and when such reporting person satisfies the aformentioned service-based conditions.</footnote>
        <footnote id="F3">Excludes previously granted restricted stock units for an aggregate of 109,330 shares of Class A Common Stock, which have different vesting schedules.</footnote>
