Dune Energy Closes Sale of South Florence Field and Amends Revolving Credit Agreement

HOUSTON, June 30 /PRNewswire-FirstCall/ -- Dune Energy, Inc. (NYSE Amex: DNE) announced today it closed on the $30 million sale of South Florence field and entered into a fifth amendment to its revolving credit agreement with its Wells Fargo Foothill.

Sale of South Florence Field

Dune closed the sale of its South Florence field to a private party on June 29, 2010 for $30 million with an effective date of May 1, 2010.  Dune expects to use proceeds from the sale to either temporarily or permanently repay borrowings under its $40 million revolving credit facility, and/or to invest in new assets or fund maintenance, repair or improvement of its existing properties and assets.

Wells Fargo Foothill Revolver

A fifth amendment to the Wells Fargo Foothill revolver has been signed reflecting modified terms associated with the sale of Dune's South Florence field.  Under the amendment, Dune's availability will be reduced to $20 million and the production and EBITDA covenants will be adjusted to reflect the resultant production and EBITDA of Dune without the South Florence field.  Currently $23 million is borrowed under the revolver and $8.5 million of letters of credit are outstanding.

Operations Update

The Wieting #33 at the Chocolate Bayou field is drilling below 10,500 feet.  Casing is anticipated to be set at approximately 11,600 feet and again at approximately 12,500 feet.  The Chocolate Bayou prospect has potential reserves of approximately 60 Bcfe which will be tested by the #33 well.  Dune will have a 50% working interest in the reserves and production associated with this high potential prospect at casing point.  During the summer we anticipate development wells being drilled at Live Oak field and Bayou Couba and post hurricane season anticipate commencing a 2-3 well program at Garden Island Bay.

James A. Watt, President and Chief Executive Officer stated, "The sale of South Florence and the fifth amendment to the revolver provide liquidity to implement our drilling program to add new reserves and production to replace those sold.  Our direct investments in the drilling program will be controlled to provide sufficient liquidity to satisfy obligations to note holders and remain within the covenants of our amended revolver.  We continue working with industry partners to structure deals to provide capital for new drilling opportunities within our existing asset base."
