New Forms of Restricted Stock Award Agreements

On October 4, 2016, the Board of Directors (the “Board”) of Paycom Software, Inc. (the “Company”) approved and adopted new forms of award agreements for grants of restricted stock under the Paycom Software, Inc. 2014 Long-Term Incentive Plan (the “LTIP”) to the Company’s chief executive officer, other named executive officers and non-executive, non-sales employees, copies of which are attached hereto as Exhibits 10.1, 10.2 and 10.3, respectively, and incorporated herein by reference.

Restricted Stock Awards

On October 4, 2016, the Board approved awards of restricted stock under the LTIP to the Company’s executive officers and certain non-executive, non-sales employees. All of the shares underlying awards to executive officers and 50% of the shares underlying awards to non-executive, non-sales employees are subject to market-based vesting conditions (“Market-Based Shares”), and 50% of the shares underlying awards to non-executive, non-sales employees are subject to time-based vesting conditions (“Time-Based Shares”). All Market-Based Shares vest 50% on the first date, if any, that the Company’s total enterprise value (calculated as described below) equals or exceeds $3.9 billion and 50% on the first date, if any, that the Company’s total enterprise value equals or exceeds $4.2 billion, in each case provided that (i) such date occurs on or before the sixth (6^th) anniversary of the grant date and (ii) the recipient is employed by, or providing services to, the Company or a subsidiary on the applicable vesting date. The Time-Based Shares vest 20% on a specified initial vesting date and 20% on each of the first four anniversaries of such initial vesting date, provided that the recipient is employed by, or providing services to, the Company or a subsidiary on the applicable vesting date. Total enterprise value is calculated based on the product of the average price of the Company’s common stock measured over 20 consecutive trading days and the number of shares outstanding (subject to certain adjustments), plus the principal amount of the Company’s outstanding funded indebtedness as of the most recent month-end less the aggregate amount of the Company’s cash and cash equivalents as of the most recent month-end. The Company’s executive officers received awards in the amounts set forth in the table below.
