2016 Salaries and Bonus Targets. On February 24, 2016, the Compensation Committee of the Board of Directors of RTI Surgical, Inc. (the “Company”) approved 2016 salaries and a bonus plan (the “2016 Bonus Plan”) providing for the payment of cash bonuses based on the Company’s operating results for the 2016 calendar year. The 2016 Bonus Plan sets target bonus amounts and performance criteria for executive officers. The performance criteria include operating margin percentage, free cash flow, base revenues and focused product revenues. As in the past, the Compensation Committee retains discretion to take other factors into account in determining bonuses and to award no bonuses even if performance criteria are met or to increase or lower such bonuses, based upon other factors.

The table below sets forth the 2016 salaries and bonus targets (expressed as a percentage of salary) for the Company’s chief executive officer, principal financial officer and three most highly compensated executive officers other than the chief executive officer and principal financial officer:

Stock Option and Restricted Stock Grants. On February 24, 2016, the Compensation Committee approved awards of stock options, time-based restricted stock and performance-based restricted stock to certain executive officers of the Company pursuant to the 2015 Equity Incentive Plan (the “Plan”). The options are exercisable for $3.31 per share (the closing price on the date of grant) and will vest in five equal annual installments beginning on the first anniversary of the date of grant. The time-based restricted stock will vest in three equal annual installments beginning on the first anniversary of the date of grant. The performance-based restricted stock will vest in three years based on achieving certain performance metrics. The time-based restricted stock awards and stock options are subject to accelerated vesting upon the occurrence of a “Change in Control” or termination without cause subject to certain conditions as provided in the Plan or the Executive Transition Agreement for the President and Chief Executive Officer and the Executive Vice Presidents.

The table below sets forth the number of stock options, time-based restricted stock and performance-based restricted stock awarded to the Company’s chief executive officer, principal financial officer and three most highly compensated executive officers:
