The Unaudited     Pro Forma Condensed Consolidated Balance Sheet assumes that the AstroTerra     acquisition took place on June 30, 2000 and consolidates our June 30, 2000     consolidated balance sheet with the balance sheet of AstroTerra. The     Unaudited Pro Forma Condensed Consolidated Statements of Operations assumes     that the Jolt and AstroTerra acquisitions occurred on January 1, 1999 and     2000 and consolidates our consolidated statements of operations for the year     ended December 31, 1999 and six months ended June 30, 2000 with the     statements of operations for those periods of Jolt and AstroTerra. See     "Unaudited Pro Forma Condensed Consolidated Financial Statements" included     herein.   (2) Includes amounts of deferred stock compensation relating to the acquisitions     of Jolt and AstroTerra of: $6.4 million, $553,000 and $4.0 million presented     in cost of sales; $13.8 million, $594,000 and $8.6     million presented in selling, general and administrative; $22.9 million,     $3.0 million and $14.3 million presented in research and development; for     the pro forma presentation of the year ended December 31, 1999, the six     months ended June 30, 2000 and the pro forma presentation of the six months     ended June 30, 2000, respectively.   (3) See note 2 of notes to consolidated financial statements for an explanation     of how the number of shares used in calculating this per share data was     determined.   (4) The as adjusted amounts give effect to the sale of shares of common stock in     this offering at an assumed initial public offering price of $     per     share, less estimated underwriting discounts and commissions, estimated     offering expenses and the application of the proceeds to working capital. |
