Projected Synergies Savings Illustration*

•

Anticipated > $36M in synergies turns $10M/year loss into >$26M operating profit

•

COGS: Test and assembly consolidation, volume pricing at subcons

•

R&D: Approximately $17M Teranetics

•

SG&A: Pubic company costs, duplicated functions

* Synergy savings per IDT estimates. PLX amounts per PLX reported non-GAAP financials.

** Gross margin, operating expenses and operating margin are Non-GAAP. See IDT’s year end fiscal 2012 earnings press release

dated April 30, 2012 for reconciliation of Non-GAAP results to the most directly comparable GAAP financial measures
