(TSX: AAV, NYSE: AAV) CALGARY, May 17, 2012 /PRNewswire/ - Advantage Oil & Gas Ltd. (" Advantage" or the " Corporation") announced today that its lenders have increased our credit facility from $275 million to $300 million. This credit facility increase in conjunction with gross proceeds from our recent $74.7 million secondary offering of Longview Oil Corp. ("Longview") shares will provide additional financial flexibility in support of future capital program requirements and general corporate purposes. Pro-forma bank debt at the end of Q1 2012 is approximately $118 million resulting in an undrawn credit facility of $182 million (after taking into consideration the increased credit facility and the net proceeds from the sale of Longview shares which is scheduled to close May 22, 2012). Advantage will continue to retain ownership of 21,150,010 Longview shares which has a value of $181 million based on the closing price on May 17, 2012. Advantage's credit facilities of $300 million are comprised of a $20 million extendible revolving operating loan facility and a $280 million extendible revolving loan facility from a syndicate of financial institutions (the " Credit Facilities"). The amounts available to Advantage from time to time under the Credit Facilities are based upon a borrowing base determination that is established primarily from the value of the company's hydrocarbon reserves. For additional detail in regard to the credit facilities, please refer to the credit facility documents which will be filed on SEDAR.
