HOUSTON, Oct. 2, 2012 /PRNewswire/ -- On October 1, 2012, Chesapeake Energy
Corporation and its wholly-owned subsidiary Chesapeake Exploration L.L.C.
(together, "Chesapeake") filed a lawsuit against Gastar Exploration Ltd. (NYSE
MKT: GST) and certain of its subsidiaries (collectively, "Gastar") in the U.S.
District Court for the Southern District of Texas. The lawsuit is based on
claims previously described in Gastar's Annual Report on Form 10-K for the
year ended December31, 2011. The lawsuit seeks rescission of certain
transactions that closed in 2005 involving Gastar's Hilltop Prospect in Leon
and Robertson Counties in Texas and an investment in Gastar's common stock by
Chesapeake. In addition to its original initial investment of $81.6 million,
Chesapeake is seeking reimbursement of additional lease and well costs
allegedly expended by them.

J. Russell Porter, Gastar's President and CEO, stated, "It is very
disappointing that Chesapeake has chosen to pursue this litigation.
Chesapeake's claims, which are based on an alleged 'mutual mistake of fact,'
are completely without merit. As Chesapeake admits in its complaint, it was
well aware of Navasota Resources L.P.'s adverse claims to the properties
before it closed the transaction with Gastar and the possibility of an adverse
outcome in the Navasota claim was addressed in the transaction documents.
Gastar rejects Chesapeake's claims and intends to vigorously defend itself
against this lawsuit."
