- JMG Exploration, Inc. ("JMG" or the "Company") (OTC:JMGE) previously announced that Newco Group Ltd., a company organized under the laws of the British Virgin Islands ("Newco"), has failed to repay a $3 million loan and accrued interest and fees that were due July 10, 2008 and that on July 22, 2008 JMG issued a formal notice of default.

Pursuant to the notice of default, JMG gave Newco 15 days to either cure the default or consummate a mutually satisfactory alternative settlement arrangement. Newco has not cured the default or consummated an alternative settlement arrangement by the deadline imposed by JMG. Accordingly, JMG has commenced the process of transferring into the name of JMG the shares of Iris Computers Ltd. that were held as collateral under the note. Once the shares of Iris are transferred into the name of JMG, JMG will have effective majority control of Iris because of the 39% equity interest in Iris represented by such Iris shares and JMG's irrevocable proxy from ESAPI representing an additional 14.5% equity interest in Iris. However, JMG's rights under the ESAPI proxy expire on December 31, 2008.

About JMG: JMG Exploration, Inc., which was incorporated under the laws of the State of Nevada on July 16, 2004, explores for oil and natural gas in the United States and Canada.
