Our audit report dated March 28, 2008, contains an explanatory paragraph that states that the Company’s recurring losses, negative cash flows from operations, and accumulated deficit raise substantial doubt about the entity’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty.
