The acquisition is expected to close by late November 2009, and is subject to customary closing conditions and purchase price adjustments.

The acquisition is comprised of approximately 3,000 wells producing primarily from the Clinton, Knox, Medina, Bradford and Oriskany formations in Ohio and Northwestern Pennsylvania. In addition, there is significant upside potential for drilling in the Knox group formation, where EnerVest has over six years of experience. With over 335,000 gross acres as part of the acquisition, EVEP has identified over 100 potential Knox drilling opportunities it plans to pursue over the next five years.

The properties, and EVEP's share of reserves and production, include:

--  Estimated proved reserves as of September 1, 2009, net to EVEP, (based
    on recent strip prices) of approximately 11.4 BCFE plus currently estimated
    Knox potential of approximately 4.2 BCFE
    
--  90 percent natural gas and 96 percent proved developed producing
    
--  Current net daily production to EVEP's interest of approximately 2.5
    MMCFE
    
--  Reserves-to-production ratio of 12.7 years for proved reserves and 17
    years for proved plus Knox potential reserves
    
--  Total lease operating costs and production taxes of approximately
    $1.80/MCFE
    
--  Pricing premium to NYMEX due to BTU content and location of $0.50 to
    $0.90 per MCFE
    

John B. Walker, Chairman and CEO, said, "This acquisition provides EVEP with a long-life, predictable base production stream and the opportunity for future production growth in a play where EnerVest has had significant drilling success over the past six years."

In conjunction with the acquisition, and consistent with its strategy of hedging a significant percentage of its production, EVEP intends to enter into arrangements to hedge a substantial portion of the acquired production volumes at or prior to closing.
