Forward-looking Statements

This presentation contains various forward-looking statements and information that are based on management’s

current expectations and assumptions about future events. Forward-looking statements are generally accompanied

by words such as “estimate,”

“project,”

“predict,”

“expect,”

“anticipate,”

“plan,”

“intend,”

“seek,”

“will,”

“should,”

“goal,”

and other words that convey the uncertainty of future events and outcomes. Forward-looking information

includes,

among

other

matters,

statements

regarding

the

Company’s

anticipated

growth,

quality

of

assets,

rig

utilization rate, capital spending by oil and gas companies, production rates, the Company's growth strategy, and

the Company's international operations.  Although the Company believes that the expectations and assumptions

reflected

in

such

forward-looking

statements

are

reasonable,

it

can

give

no

assurance

that

such

expectations

and

assumptions

will

prove

to

have

been

correct.

Such

statements

are

subject

to

certain

risks,

uncertainties

and

assumptions, including, among others: general and regional economic conditions and industry trends; the

continued

strength

of

the

contract

land

drilling

industry

in

the

geographic

areas

where

the

Company

operates;

decisions about onshore exploration and development projects to be made by oil and gas companies; the highly

competitive nature of the contract land drilling business; the Company’s future financial performance, including

availability, terms and deployment of capital; the continued availability of qualified personnel; changes in

governmental regulations, including those relating to the environment; the political, economic and other

uncertainties encountered in the Company's international operations and other risks, contingencies and

uncertainties, most of which are difficult to predict and many of which are beyond our control. Should one or more

of these risks, contingencies or uncertainties materialize, or should underlying assumptions prove incorrect, actual

results may vary materially from those expected.  Many of these factors have been discussed in more detail in the

Company's annual report on Form 10-K for the fiscal year ended December 31, 2008 and quarterly report on Form

10Q for the quarter ended March 31, 2009.  Unpredictable or unknown factors that the Company has not discussed in

this presentation or in its filings with the Securities and Exchange Commission could also have material adverse

effects

on

actual

results

of

matters

that

are

the

subject

of

the

forward-looking

statements.

All

forward-looking

statements

speak

only

as

the

date

on

which

they

are

made

and

the

Company

undertakes

no

duty

to

update

or

revise

any forward-looking statements. We advise our shareholders to use caution and common sense when considering

our forward looking statements.

13

Challenging Year Ahead

Oversupply of natural gas in U.S. putting downward pressure

on price expectations for 2009.

Lower natural gas price expectations, plus depressed stock

prices, tight credit markets and global recession, have caused

operators to significantly reduce 2009 capital budgets.

For the week ending 5/8/09, the U.S. land rig count was 868

rigs, a decline of 55% from the August 2008 peak of 1,938

rigs*.  The more recent diminishing rate of decline in the U.S.

land rig count suggests a bottom in the industry cycle is near.

Pioneer recently cold stacked 6 rigs that were operating in

Western Oklahoma.
