Arena’s Chief Executive Officer, Mr. Tim Rochford, stated, “We continue to ramp up our 2007 development program. Our first quarter resulted in 28 development wells drilled and 13 re-fracs on existing wells on our Fuhrman-Mascho property, where we continue to have a 100% success rate on newly drilled development wells. We have announced an increase in our 2007 CAPEX budget to $104 million, adding an additional 20 development wells to be drilled on our Fuhrman-Mascho lease. In the second quarter, we will continue to concentrate on the development of our Permian Basin properties, as we have budgeted over 30 new development wells to be drilled on our Fuhrman-Mascho lease along with continued infrastructure improvements, water line installations and well conversions in New Mexico.”

Non-GAAP Financial Measures:
Earnings for the first quarter 2007 include a non-cash charge for stock based compensation of $639,624. Excluding such item, the Company’s earnings would have been $0.39 per diluted share. The Company believes results excluding these items are more comparable to estimates provided by security analysts and, therefore, are useful in evaluating operational trends of the Company and its performance, compared to other similarly situated oil and gas producing companies.
