HOUSTON, March 5, 2012 /PRNewswire/ -- Gastar Exploration Ltd. (NYSE Amex: GST) announced today that the Borrowing Base under its Senior Secured Revolving Credit Facility has been confirmed by the lending participants in the amount of $100 million, effective immediately. The Borrowing Base was previously set at $50 million. Presently, Gastar has drawn $27 million under the revolving credit facility, resulting in $73 million of unused borrowing capacity. The next borrowing base redetermination is scheduled to occur in November 2012. In addition, Gastar is also pleased to provide an update on the status of its Gastar Exploration USA, Inc. Series A Preferred Stock offering. To date in 2012, Gastar USA has issued 1,472,142 shares for net proceeds of $28.0 million ( $36.8 million in face value) resulting in issuances from inception to date of 2,836,685 shares of the Series A Preferred Stock ( $70.9 million in face value) for net proceeds of $55.4 million. Gastar's Chief Financial Officer, Michael A. Gerlich, commented, "We believe the additional liquidity afforded by this borrowing base increase, along with the proceeds from the continued issuance of our Series A Preferred Stock and internally generated cash flow will be sufficient to fully fund Gastar's $134.2 million 2012 capital expenditures budget. The increase in the amount of the borrowing base is a reflection of the value created by the initial phase of development of Gastar's liquids-rich Marcellus Shale position."
