PostRock Acquires Oklahoma Properties

OKLAHOMA CITY, Oct. 15, 2013 (GLOBE NEWSWIRE) -- PostRock Energy Corporation
(Nasdaq:PSTR) today announced that it was acquiring approximately 22,000 net
acres of leasehold in Pottawatomie, Cleveland and McCain Counties in central
Oklahoma. The properties are being purchased for $10 million, including $3.0
million of cash and $7.0 million of PostRock common stock. Approximately 9,000
of the 22,000 net acres are held by production.Currently, production
approximates 50 net barrels of oil equivalent ("BOE") per day from a variety
of formations.Producing depths range from 3,000 to 6,000 feet.Closing is
expected within 30 days, with an effective date of July 1, 2013.

PostRock estimates that the net proved reserves being acquired total 574,000
BOE, of which 95% is oil and 60% is classified developed. On that basis,
acquisition cost equates to $17 per BOE of proved reserves.The Company
believes there is significant potential to develop additional reserves in
multiple reservoirs. The most significant is the Woodford, a formation which
is believed to range from 200 feet to 300 feet in thickness at depths of 4,500
feet to 6,500 feet across the entirety of the acreage.

Commenting, Terry W. Carter, President and Chief Executive Officer of the
Company, said: "This transaction is an important step in our effort to add oil
reserves and development opportunities in central Oklahoma.The acquisition
brings our leasehold position in this area to more than 34,000 net acres.It
adds production, proved reserves and meaningful upside potential from
historically productive reservoirs as well as significant upside potential
from the Woodford.With this acquisition, we believe we could have as many as
200 potential drilling locations with exposure to more than 10 million BOE's
of recoverable reserves.Importantly, the sellers' willingness to become major
stockholders in the Company through the transaction is a significant third
party endorsement of how far the Company has come."
