Employee Benefit Plan

We have a defined contribution

401

(k) plan (“Plan”) covering substantially all of our employees. In the past

three

calendar years, we made matching cash contributions equal to

50%

of each participant’s contribution during the Plan year up to a maximum amount equal to the lesser of

3%

of each participant’s annual compensation or

$8,250,

$8,100

and

$7,950

for the years ended

December 31, 2018,

2017

and

2016,

respectively. Such amounts were recorded as expense in the corresponding years. We

may

also contribute additional discretionary amounts to the Plan as we determine. For the years ended

December 31, 2018,

2017

and

2016,

we contributed

$0.7

million,

$0.6

million and

$0.6

million, respectively, to the Plan.

No

discretionary contributions have been made to the Plan since its inception.
