On March 31, 2009, the Company acquired from Nortel Networks Ltd., Nortel Networks Inc. and other Nortel entities ("Nortel") certain assets and liabilities related to Nortel's Layer 4-7 Application Delivery Business ("Alteon").

In performing the purchase price allocation, the Company considered, among other factors, analyses of historical financial performance, highest and best use of the acquired assets and estimates of future performance of Alteon's products.

The following unaudited condensed combined pro forma information for the year ended December 31, 2009, gives effect to the acquisition of Alteon Business as if the acquisition had occurred on January 1, 2009. The pro forma information is not necessarily indicative of the results of operations, which actually would have occurred had the acquisition been consummated on that date, nor does it purport to represent the results of operations for future periods. For the purposes of the pro forma information, the Company has assumed that net loss includes additional amortization of intangible assets related to the acquisition of $ 928 in 2009.
