Explanation of Responses:

( 1 )Restricted stock vesting annually and ratably over three years from the date of issuance. ( 2 )Each Performance Stock Unit ("PSU") represents a contingent right to receive one share of the Company's common stock ("Target PSUs"). The number of PSU's to which an Executive will be entitled will be determined based on a 1-year measurement period from January 1, 2022 to December 31, 2022 based on achievement of established targets with respect to the Company's revenue growth and net debt leverage, each weighted at 50% of the Target PSUs. Based on actual results, each Executive will be eligible to receive 0% to 200% of the Target PSUs. The PSUs will be earned over a 3-year period beginning January 1, 2022, cliff vesting on December 31, 2024. After the payout is determined, the number of shares to be provided is subject to modification based on the percentage change in the price of the Company's common stock from January 1, 2022 to December 31, 2024 relative to the percentage change in the price of the common stock of certain companies in the environmental and facilities industry.
