Non-GAAP Financial Measures

Odyssey

uses

adjusted

EBITDA

as

a

measure

of

performance

to

demonstrate

earnings

exclusive

of

interest

and

certain

non-cash

events.

Odyssey,

in

its

daily

management

of

its

business

affairs

and

analysis

of

its

monthly,

quarterly

and

annual

performance,

makes

its

decisions

based

on

cash

flows,

not

on

the

depreciation

of

assets

obtained

through

historical

activities.

Odyssey,

in

managing

its

current

and

future

affairs,

cannot

affect

the

depreciation

and

amortization

of

its

assets

to

any

material

degree,

and

therefore

uses

adjusted

EBITDA

as

its

primary

management

guide.

Since

an

outside

investor

may

base its evaluation of Odyssey’s performance based on Odyssey’s net income or loss not its cash flows, there is a limitation to the adjusted EBITDA

measurement.

Adjusted EBITDA is not, and should not be considered, an alternative to net income or loss, loss from operations, or any other measure

for determining operating performance of liquidity, as determined under accounting principles generally accepted in the United States (GAAP).

Adjusted

EBITDA

is

a

supplemental

non-GAAP

financial

measure.

The

most

directly

comparable

GAAP

measure

to

adjusted

EBITDA

in

Odyssey’s case

is net income (loss). Adjusted EBITDA is equal to net income (loss) excluding: (a) total other income (expense); (b) depreciation and amortization; (c)

stock-based compensation; and (d) income taxes.
