(NYSE: OAS) (&#8220;Oasis&#8221; or the &#8220;Company&#8221;) today announced that the lenders under its revolving credit agreement completed their regular semi-annual redetermination of the borrowing base, resulting in an increase to the borrowing base from $1,750 million to $2,000 million.  However, the Company elected to limit the lenders&#8217; aggregate commitment to $1,500 million.  The lenders' aggregate commitment can be increased to the full $2,000 million borrowing base by increasing the commitment of one or more lenders. &#160;Oasis did not add any banks to the bank group.  The next redetermination of the borrowing base is scheduled for April 1, 2015.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">About Oasis Petroleum Inc.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Oasis is an independent exploration and production company focused on the acquisition and development of unconventional oil and natural gas resources, primarily operating in the Williston Basin.
