Going Concern Note			We currently do not have sufficient cash or commitments for financing to sustain our operations for the next twelve months. We will require additional financing in order to execute our operating plan and continue as a going concern. Our management's plan is to attempt to secure adequate funding to bridge the commercialization of our patent licensing and barcode ecosystem businesses. We cannot predict whether this additional financing will be in the form of equity, debt, or another form and we may not be able to obtain the necessary additional capital on a timely basis, on acceptable terms, or at all. In the event that these financing sources do not materialize, or that we are unsuccessful in increasing our revenues and profits, we may be unable to implement our current plans for expansion, repay our debt obligations as they become due or respond to competitive pressures, any of which circumstances would have a material adverse effect on our business, prospects, financial condition and results of operations. Should our lender, YA Global Investments, L.P. ("YA Global") choose not to provide us with continued financing, or if we do not find alternative sources of financing to fund our operations or if we are unable to generate significant product revenues, we may not have sufficient funds to sustain our current operations. Our debenture obligations to YA Global currently mature on August 1, 2013.
