Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, our revenue is difficult to predict and may vary substantially from quarter to quarter.

The timing of our revenue is difficult to predict. Our sales efforts involve educating our customers about the use and benefit of our products, including their technical capabilities and potential cost savings to an organization. Customers typically undertake a significant evaluation process that has in the past resulted in a lengthy sales cycle, in some cases over twelve months. Also, as our channel model distribution strategy evolves, utilizing value-added resellers, distributors, systems integrators and service providers, the level of variability in the length of sales cycle across transactions may increase and make it more difficult to predict the timing of many of our sales transactions. We spend substantial time, effort and money in our sales efforts without any assurance that our efforts will produce any sales. In addition, product purchases are frequently and increasingly subject to budget constraints, multiple approvals, and unplanned administrative, processing and other delays. Beginning in early 2008, product purchases have been delayed by the volatile U.S. and global economic environment, which has introduced additional risk into our ability to accurately forecast sales in a particular quarter. If sales expected from a specific customer for a particular quarter are not realized in that quarter or at all, revenue will be harmed and we may miss our stated guidance for that period.
