Chaparral Energy Closes on the Acquisition of all of the Marmaton Assets of Cabot Oil

Acquisition Essentially Doubles Chaparral's Footprint Giving Chaparral the Largest
Position in the Industry for the Panhandle Marmaton Play

OKLAHOMA CITY (December 19, 2013) – Chaparral Energy, Inc., based in Oklahoma City, Oklahoma, announced today that it has closed the acquisition from Cabot Oil & Gas Corp. of its Panhandle Marmaton Assets for $160.1 million, subject to post-closing adjustments. The transaction is expected to add approximately 2,000 barrels of oil equivalent per day, based on Cabot’s September, 2013 production, and 66,000 net acres to Chaparral’s existing position in the Panhandle Marmaton Play. The acquisition essentially doubles Chaparral’s holdings to 126,000 net acres in the Panhandle Marmaton Play and reflects its increased focus on high-quality oil plays with excellent well economics.

Located in Beaver and Texas Counties, Oklahoma, and Ochiltree County, Texas, production from the purchased assets is approximately 81 percent oil with total reserves estimated to be approximately 32.0 million barrels of oil equivalent (MMBoe) and proved reserves estimated to be approximately 5.5 MMBoe based upon development of the acreage with two (2) wells per section.

As previously stated, Chaparral’s Chairman, CEO and President Mark Fischer stated “I see long-term, sustainable growth for the Company by focusing on the key plays in the Mid-Continent area. As a result of this acquisition, Chaparral holds the largest acreage position in this active play.”

The Cabot acquisition increases Chaparral’s growth potential through the addition of approximately 450 drilling locations targeting the Marmaton Lime formation which typically generate rates of return in the 40 to 70 percent range. In addition, this area offers significant upside associated with drilling numerous horizons in a stacked-pay environment.

This purchase clearly supplements Chaparral’s existing footprint in Oklahoma and solidifies its entry into a new phase of growth, concentrating on oil and gas exploration and production in the Mid-Continent.

Concurrent with the closing of the Cabot acquisition, the Company’s borrowing base was increased to $600.0 million.
