Synopsys (SNPS)

ArchPro Design Automation, Inc. (ArchPro)

The Company acquired ArchPro on June 14, 2007.

ArchPro’s technologies enable engineers to address power management challenges in multi-voltage designs from chip architecture to Register Transfer Language (RTL) and gate-level design. These technologies allow verification of modern power management techniques such as power gating, substrate biasing, dynamic voltage and frequency scaling. The Company believes that this acquisition will help the Company enhance its power management verification technologies.

The Company paid $12.9 million in cash on June 14, 2007 for the outstanding shares of ArchPro. The total purchase consideration consisted of:

6

Acquisition-related costs of $1.7 million consist primarily of legal, tax and accounting fees, estimated facilities closure costs and employee termination costs. As of July 31, 2007, the Company had paid $0.3 million of the acquisition-related costs and has a remaining balance of $1.4 million.

Under the agreement, the Company agreed to pay up to an additional $4.0 million over three years to the former ArchPro shareholders based upon achievement of certain booking and product milestones. This contingent consideration is considered to be additional purchase price.
