Gasco Energy Announces Increased Borrowing Base on Revolving Line of Credit

DENVER – (PR Newswire) – March 8, 2007 – Gasco Energy, Inc. (AMEX: GSX) today announced that it has received a re-determination of its borrowing base under its $250 million revolving line of credit agreement led by JPMorgan.  The borrowing base, reflecting the maximum amount that may be outstanding under the credit facility at any time, is increased to $37 million from $25 million at the previous re-determination in fall 2006.  The borrowing base is determined by reference to Gasco’s proved reserves at December 31, 2006.  Loans made under this revolving credit agreement are secured by a pledge of the capital stock of Gasco's significant subsidiaries, guaranties by Gasco’s significant subsidiaries, and mortgages on substantially all of the Company’s oil & gas properties.

Each loan bears interest at a Eurodollar rate or a base rate, as requested by Gasco, plus an applicable percentage based on Gasco's usage of the facility.  The applicable margin above the Eurodollar rate ranges from 1.25% to 2.00% depending on the Company’s usage under the credit line.  In addition, under the terms of the $250 million credit agreement, Gasco pays a commitment fee quarterly in arrears based on a percentage multiplied by the daily amount that the aggregate commitments exceed borrowings under the agreement.  Gasco did not borrow any funds at the time of execution of the credit agreement.  For further detail please refer to Gasco’s disclosure on Form 8-K filed today with the SEC.

The credit facility is available to provide funds for the exploration, development and/or acquisition of oil and gas properties, to refinance existing indebtedness and for working capital and other general corporate purposes. Interest on funds drawn will be paid monthly with the principal due March 2010. The agreement provides for semi-annual evaluation of the borrowing base, which will be determined as a percentage of the discounted present value of the Company’s oil and natural gas reserves.

“Borrowing capacity under our revolving line of credit adds additional flexibility to our growth capital needs,” said King Grant, Gasco’s Chief Financial Officer.  “With this credit facility, which is tied to our reserve base, we are further capable of funding our drilling & completion plans on lower-risk, development projects in our Riverbend project in Utah.  Cash on hand, cash flow generated from our producing wells and our ability to borrow under this credit facility are expected to allow Gasco to successfully fund its previously announced $40 million 2007 drilling program.”
