Forward-looking statements are based on the reasonable assumptions, estimates, analyses and opinions of management made in light of its experience and its perception of trends, current conditions and expected developments, as well as other factors that management believes to be relevant and reasonable in the circumstances at the date that such statements are made, but which may prove to be incorrect. Such factors impacting forward-looking information include, among others: risks relating to the global economic climate; dilution; Abaxx’s limited operating history; future capital needs and uncertainty of additional financing; the competitive nature of the industry; currency exchange risks; the need for Abaxx to manage its planned growth and expansion; the effects of product development and need for continued technology change; protection of proprietary rights; the effect of government regulation and compliance on Abaxx and the industry; acquiring and maintaining regulatory approvals for Abaxx’s products and operations; the ability to list Abaxx’s securities on stock exchanges in a timely fashion or at all; network security risks; the ability of Abaxx to maintain properly working systems; reliance on key personnel; global economic and financial market deterioration impeding access to capital or increasing the cost of capital; and volatile securities markets impacting security pricing unrelated to operating performance.

In addition, although Abaxx has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, or intended.
