10 .	Employee Benefit Plan

We have a defined contribution

401(k)

plan (the “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

of each participant’s annual compensation or

$7,950,

$7,950

and

$7,800

for the years

2016,

2015

and

2014,

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

may

also contribute additional discretionary amounts to the Plan as we

may

determine. For the years ended

December

31,

2016,

2015

and

2014,

we contributed to the Plan

$0.6

million,

$0.3

million and

$0.2

million, respectively. No discretionary contributions have been made to the Plan since its inception.
